Industrial refrigerators for storing vegetables. Refrigerated warehouses for fruits and vegetables Industrial refrigerators for storing vegetables
Having your own vegetable garden is a great way to eat foods high in vitamins more often with a minimum of harmful additives, and even save on it. Another thing is that in our country the season fresh vegetables and fruit lasts far from all year round, and in a canned form, all these gifts of nature easily lose a certain part of their benefits.
If your own vegetable garden brings significant amounts of harvest and you want to keep it mostly fresh, you should purchase a special refrigerator for vegetables and fruits.
The necessary conditions
For most modern consumers, it is no secret that even an ordinary home refrigerator has zones with different temperatures. This is not a minus of the organization of equipment, but the ability to place each product in the conditions that are optimal for it. A typical “vegetable” spot is a special cell or box at the bottom of the main compartment, but conditions are not ideal there, and there is little space.
The optimal refrigerator for vegetarian ingredients can have very different freezing temperatures, but always with adjustable freezing temperatures. If the camera is able to do this in automatic mode, then usually the temperature inside it is from 2 to 7 degrees Celsius. But at the same time it is important to maintain the humidity inside the chamber within 70-95%. Some models allow temperature regulation in the range of 8-20 degrees, but then the maximum allowable humidity will be 90%.
In some cases, for storing vegetables and fruits, you can also use special heating chambers, in which the temperature can vary from 2 to 18 degrees above zero.
On an industrial scale, equipment with a capacity of up to 250 tons is used, but at home, of course, cameras of a more modest size are used.
Multiple compartments are highly desirable as temperatures are too low for food vegetable origin are only relevant for a short time. In order to avoid spoilage of such food, it cannot be sharply defrosted, therefore the selected refrigerator should be able to increase the temperature gradually, literally by one or two degrees.
Principle of operation
The release of special refrigerators for vegetables and fruits is not just a marketing ploy to sell the same unit under a new name, but a completely separate piece of equipment. The described products are susceptible to the influence of various microorganisms, and can also lose water during the freezing process, which spoils both the taste and appearance.
The first thing that such a unit does when loaded is shock freezing. It differs in that there is a sharp drop in temperature, which usually does not reach negative values. This approach allows you to effectively destroy all possible bacteria that could provoke rotting or decomposition processes, but at the same time, for many vegetables and fruits, the temperature soon rises, otherwise the tropical fruits will simply be destroyed from the inside.
A special temperature of permanent storage is set for each type of fruit. For example, for carrots, you need a strict zero, for grapes, you can make a relaxation - up to 2 degrees Celsius, apples will not deteriorate even at +4, but southern bananas should not be stored at temperatures below +7, although above +12 is also not worth it.
Of fundamental importance is not only the temperature inside the chamber, but also the humidity, which must be constantly maintained at a certain level. Considering that in such a unit, vegetables and fruits, being closed, can be stored for months, the manufacturer is obliged to think over the ventilation system, because it is simply impossible to regulate the humidity level otherwise. The system carefully monitors the level of moisture in the air inside the chamber and, as needed, draws in air from the outside so that the gifts of nature do not get stuck.
In most cases, such equipment performs all complex calculations by itself, therefore, no special knowledge is required on the part of the consumer. The device assumes the presence of several built-in programs, each of which is designed for a particular fruit or vegetable - the owner can only press the appropriate button and be sure that the contents of the refrigerator will not deteriorate.
Criterias of choice
If it was decided that such equipment would be very useful at home, then before making a purchase it is worth paying attention to the characteristics that should be followed when choosing.
- Dimensions (edit)... The house is not a storage room, so the camera still needs to be placed somewhere so that it does not interfere with anyone. A separate moment - it must freely pass through the existing doorways, because usually such equipment is not disassembled.
- Multiple temperature zones... Large stores can afford a single-chamber unit for each type of vegetable or fruit, but for a home it is desirable to have several sections so that the entire crop fits into one chamber. Each section must be regulated separately, because all products cannot be stored at the same temperature.
- Volume... Refrigerating chambers for fruits and vegetables are available in volumes from 35 liters. The owner must think in advance how much volume he needs, since small refrigerator will not solve its problem, and a large unit is much more expensive, and even with the predominant downtime, it still does not provide adequate storage conditions.
- Material... It is desirable that expensive equipment is durable and does not lose its attractive appearance as long as possible. These requirements are best met by stainless steel cases, but painted refrigerators quickly wear out on the outside.
- Cooling type... Static refrigeration cabinets work on the principle of natural circulation of air mass, therefore, the temperature difference in individual zones in them often differs in the location of the shelf - top or bottom. Dynamic models forcibly blow cold air using a fan, so here the location of the temperature zones in to a greater extent subject to user preferences.
Refrigerators for storing fruits and vegetables provide:
- storage chambers with automatic temperature control from –2 to + 7 ° С and relative humidity of 70-95%;
- ripening chambers for fruits and vegetables with automatic temperature control from 8 to 20 ° C and relative humidity of 80-90%;
- fruit and vegetable processing room (bulkheads, packing and packaging) with automatic temperature control from 12 to 15 ° С without regulation of the relative air humidity;
- heating chambers with temperatures from –2 to + 20 ° С;
- fumigation chambers (on distribution refrigerators).
Storage chambers capacity - from 50 to 250 tons and more. The storage chambers must be filled within 7-10 days, which will ensure uniform cooling of all fruits. When loading the chambers, the refrigeration equipment must be turned on. Additional loading of fruits and vegetables with a temperature above 8 ° C into chambers with a capacity of up to 200 T is allowed up to 8%, and into chambers over 200 T - 6% of the capacity of the chambers.
The degree of chamber loading influences the relative humidity of the air in it. So, depending on the degree of loading of the chamber in the amount of 100, 50 and 25%, the relative humidity in it will be 86, 78 and 68%, respectively. A decrease in the degree of loading also affects the deterioration of the circulation conditions.
Fruits and vegetables that are most sensitive to insufficient air humidity (with a weak water-holding capacity), it is more expedient to store in smaller chambers located in the middle of the refrigerator circuit and having a smaller surface of the outer fences.
With absence special premises for processing and sorting fruits during the shipment period, it is necessary to select one of the chambers in which the temperature is maintained at 2-6 ° C when preparing batches for shipment to distribution refrigerators and 10-12 ° C when shipped to the retail network.
When shipping fruits to distribution refrigerators, an increase in their temperature during the bulkhead period is allowed only for a short time not higher than 2-4 ° C.
Before shipment to the retail network in the warm season, the temperature of the fruits must be increased gradually over 2-3 days in order to avoid condensation on them. At the same time, the air temperature in the room is maintained at 2-3 ° C above the temperature of the product to be insulated, the relative humidity is 75-80%.
Some fruits and vegetables (pears, tomatoes, etc.) do not ripen during storage, therefore, several days before sale, they are transferred to a room with increased air circulation and kept there for 3-7 days at a temperature of 18-20 ° C and relative humidity 90%.
Refrigerated chambers for vegetables and fruits
The choice of a suitable storage technology ensures that the final product is preserved in its original freshness. Lower storage temperatures provide a longer shelf life. Industrial refrigeration chambers and blast freezers can help you store your products.

Introduction
The most common way to store fruits and vegetables is cold storage. The duration of storage is determined by a number of factors, ranging from the influence of soil and climatic conditions of cultivation of crops, varietal characteristics, rational use of fertilizers, agricultural technology, irrigation, a system of protection against pests, diseases and weeds, terms and methods of harvesting, commercial processing and, of course, methods and storage conditions.
All biochemical processes in fruits and vegetables are temperature dependent. At high temperatures, there is an accelerated metabolism, loss of moisture, vitamins, organic substances. Simply put, vegetables begin to "age" faster and become unusable.
In order to significantly reduce the natural weight loss of fruit and vegetable products and maximize the shelf life, it is necessary to cool the products as soon as possible after harvest and maintain optimal storage parameters.
Refrigerated warehouses are complexes of buildings and structures for acceptance, post-harvest and pre-implementation processing and storage of products. Buildings can be interconnected to provide a single technological process... The main requirements for the preservation of vegetables and fruits are to ensure the required temperature regimes for each type of fruit and certain ventilation regimes.
Humidity and temperature
After harvesting the fruits and placing them in refrigerated warehouses, the most important processes for long-term storage are the processes of respiration and transpiration.
Therefore, for optimal storage of fruits and vegetables, it is necessary to create and maintain an optimal temperature and humidity regime, an optimal concentration of oxygen and carbon dioxide, and the removal of ethylene.
The optimal parameters of temperature and humidity for conventional refrigerators for the main types of crops are shown in the table.
| Name | Temperature, ° С | Humidity, % | Storage period |

Controlled atmosphere mode
A refrigerator with a controlled gas environment allows you to sharply reduce the respiration rate of fruits, which contributes to their longer and better storage. For different crops and varieties, the minimum permissible oxygen concentration can be determined by reducing it until ethanol is formed. If the process of ethanol formation is determined at the earliest stage, then it can be stopped by increasing the oxygen concentration by tenths of a percent, thus determining the minimum permissible oxygen concentration for a given variety.
The main condition for maintaining an optimally low oxygen concentration is a hermetically sealed chamber. Another important component of the atmosphere that affects the storage of fruit and vegetable products is carbon dioxide, which is released by the fruit as a result of respiration and in high concentrations inhibits this process. A very high concentration of CO 2 leads to the death of products as a result of the conversion of sugars into ethanol.
For most fruits and vegetables, the optimum carbon dioxide concentration is between 0.5% and 5%. The excess content of CO 2 in the chambers of refrigerators with a controlled atmosphere is removed using carbon dioxide adsorbers. A quick achievement of the optimal oxygen concentration is achieved by purging the chambers with nitrogen. Currently, effective methods have been developed for creating and maintaining the concentration of a controlled atmosphere using an automatic computer gas-analytical control system.
Gas regulation equipment
- C.A. (Controlled Atmosphere) - controlled environment (PC).
- RCA (Rapid Controlled Atmosphere) - rapid decrease in oxygen concentration.
- U.L.O. (Ultra Low Oxygen) - ultra-low oxygen content in the chamber.
- ILOS (Initial Low Oxygen Stress) - an ultra-fast reduction of the oxygen level in the chamber in a short period of time.
- LECA (Low Ethylene Controlled Atmosphere) - reduction of ethylene level in the chamber using a catalytic converter.

Construction of refrigerated warehouses
During the construction of a cold store for the implementation of storage technology, one should take into account the specific requirements for fruits and vegetables to maintain a high relative humidity in the chambers (88 - 95%). Therefore, it is very important to correctly calculate and select refrigeration equipment with an appropriate cooling scheme, cooling capacity, air exchange rate, technical characteristics of air coolers, air speed, etc.
The unit cost per unit of capacity for the construction of a new refrigerator depends on the project, i.e., the size and number of chambers, the availability of a commodity processing room, expedition, shipping locks, the technical level of the cooling system and the controlled atmosphere. This figure can be from 40 to 75 eurocents per 1 kg of stored products.

Secrets of grape storage
After harvesting the grapes must be properly packed and chilled. These are two main factors for successful storage grapes. Storage conditions for grapes also depend on the factors of the storage environment - these are temperature, air movement in the room, relative humidity.
The lower the air temperature, the longer the grapes can be stored. The optimum temperature for storing grapes is considered to be from 0 to +1.5 degrees. The relative humidity is desirably high, more than 95%.
The increased ventilation rate of the cold air ensures the removal of high temperature during cooling, but during storage, air movement should be reduced to prevent drying out of the grapes.
The grapes are fumigated with sulfur dioxide to kill various fungi that can cause large losses of grapes even when stored at low temperatures. Any infection that is present in the berry continues to develop during storage, and the use of sulfur dioxide is imperative to prevent the spread of the disease to neighboring healthy grapes.
Composition of the gas environment for storing grapes
To date, formulas for the composition of the gas environment for storing the following grape varieties have already been derived.
V last years with the growth in the construction of suburban housing, cottages, the number of orders for refrigeration chambers for storing fruits and vegetables at a stable positive temperature increased. When stored properly in the refrigerator compartment, vegetables and fruits retain their freshness and vitamins for a long time.
Proper storage of vegetables and fruits means adherence to temperature and humidity conditions. It is necessary to maintain the same air temperature throughout the year. Accordingly, in the summer it is necessary to cool, and in the winter - to heat the volume of the refrigerating chamber or storage for vegetables and fruits. Cooling of the refrigerating chamber and storage is carried out using a refrigeration unit, using air coolers installed in the chamber. Heating is carried out either by heaters operating on different types energy (electrical, heat from water, pre-heated air, etc.), or using the same air coolers, turning on their heating elements.
Refrigerators (cabinets) for storing wine
For connoisseurs of good wine, having their own collection has already become a good tradition. But keeping good wine in the refrigerator or room temperature unacceptably.
Especially for wine connoisseurs, our company is ready to offer the design and installation of refrigeration chambers for storing wine.
Cold rooms for storing fur coats
Control over the temperature and humidity conditions of food storage in refrigerated chambers, warehouses, storage facilities for vegetables, fruits, etc. is performed daily with the help of thermometers and psychrometers installed in a conspicuous place, remote from doors and evaporators (Ch. 6 Sanitary regulations № 2.3.6.1066-01).
The air temperature inside refrigerators, cold rooms, refrigerated display cases, and other refrigeration equipment is checked daily as part of the production control program.
All refrigeration units in trade organizations are equipped with thermometers to control the temperature regime of food storage. Usage mercury thermometers to control the operation of refrigeration equipment is not allowed. It is recommended to equip cooled chambers with a thermostat and (or) systems of automatic regulation and registration of temperature and humidity conditions.
Refrigerating chambers
Refrigerating chambers are collapsible structures made of heat-insulated panels and are designed for cooling and storage of fresh and chilled food at temperatures from 0 ° C to + 10 ° C.
Refrigerating chambers, according to their purpose, are divided into medium-temperature, low-temperature and fast freezing chambers. Temperature regimes in commercial refrigerating chambers do not coincide with those in commercial refrigerating cabinets.
Medium-temperature chambers are designed for long-term storage of chilled products at temperatures from -5 to + 5 ° C.
Low-temperature chambers are designed for long-term storage of frozen products at temperatures from -15 to -25 ° C.
Chambers for quick freezing ("shock freezing") have temperatures no higher than -35C and are recommended to preserve the gastronomic, taste and nutritional qualities of products.
The most modern method of creating reliable and highly effective thermal insulation of refrigerating chambers is the use of three-layer sandwich panels with insulation in the form of injection-molded polyurethane foam. Polyurethane is lightweight, durable, heat resistant, shape stable and has excellent thermal insulation properties. In addition, polyurethane foam is highly resistant to water, which distinguishes it favorably, for example, from mineral wool. The main danger of using mineral wool for thermal insulation of refrigerating chambers is its hygroscopicity, and when the thermal insulation is saturated with water, the thermal conductivity increases significantly, up to total loss thermal insulation properties. Since it is practically impossible to provide full protection of mineral wool insulation from moisture, especially in refrigeration chambers (a large difference between external and internal temperatures), its saturation with moisture is inevitable. Therefore, the service life of mineral wool thermal insulation is short and in many cases does not exceed two to three years. On the contrary, polyurethane foam, due to its chemical composition and closed porous structure, has insignificant moisture absorption (up to 0.2% by volume with air humidity up to 100%), which guarantees the preservation of high thermal insulation properties in conditions of high humidity.
In addition, three-layer polyurethane foam sandwich panels have sufficient load-bearing capacity and are widely used in the construction of both small refrigerating chambers and large refrigerated warehouses.
The dimensions of standard refrigerating chambers are variable in steps of 300 mm in length and width, in steps of 100 mm in height. The volumes of the chambers can be from 3 m3 and more. The maximum panel length is 6.4 m. If the dimensions of the refrigerating chamber exceed the maximum panel length, then a supporting frame made of special profiles is mounted inside or outside the chamber. It is also possible to attach panels to walls and building frame elements.
As a standard facing of the outer and inner surfaces of the panel, most Russian and foreign manufacturers use hot-dip galvanized steel sheet 0.5-0.6 mm thick with various paints and varnishes, or polymer coatings safe for food. Floor panels are made, as a rule, with a surface in the form of corrugated sheet stainless steel, sheet aluminum, galvanized steel sheet with a special non-slip plastic coating. If trolleys are supposed to be used in the refrigerating chamber to move goods, then reinforced floor panels or a special floor covering are required. Medium-temperature chambers with temperatures above 0 ° C can be without floor panels, which significantly reduces their cost.
The connection of panels during assembly, depending on the design, is carried out in two main ways: silicone sealants, elastic seals and fixing angles, as well as more modern and technological - by means of built-in eccentric hook locks. The second way provides whole line advantages: excellent mechanical strength, rigidity, uniform and tight junction of the panels, the possibility of installation from the inside of the chamber without using special tool, which allows you to assemble the camera close to the wall of the room. In addition, the "lock" method of connecting the panels makes it possible to repeatedly assemble and disassemble the chamber without damaging the fasteners, which is especially important for those trade enterprises and Catering who rent premises.
Most manufacturers complete prefabricated refrigerating chambers made of sandwich panels with hinged or, if necessary, sliding doors of various sizes with electric heating of the opening and a compensating valve for low-temperature modes. On request, a tape curtain made of PVC film can be installed in the doorway, which significantly reduces heat flow into the chamber when the door is opened. As a rule, manufacturers or suppliers of complete prefabricated refrigerating chambers offer rack and frame-hook equipment complete with chambers.
Refrigerated display cases
Refrigerated display cases are used to sell a wide variety of food products: sausages, cheeses, meat and fish delicacies, confectionery, etc.
Manufacturers offer not only refrigerated display cases, but also heat displays, which are intended for the sale of ready-made meals in a heated state.
According to the temperature of the exposition surface, refrigerated showcases are divided into medium-temperature and low-temperature ones.
In medium-temperature display cases, the temperature on the display surface ranges from -1 to + 6 ° C.
In low-temperature models of refrigerated display cases, the temperature range at the exposition is from -18 to -25 ° C.
However, refrigerated counters with temperatures from -4 to -12 ° C are also used.
According to the location of the refrigeration unit, showcases are available with built-in and with an external refrigeration unit.
Models with a built-in refrigeration unit have a shallow exposure depth, usually no more than 75 cm, due to the static type of cooling. This refrigeration equipment is used in small shops that work on the "over the counter" principle, that is, with the seller. The installation of such refrigerated counters in the sales area does not involve a large volume installation works- it is enough to install them in the required place and connect them to the power grid.
Refrigerated display cases with a portable unit are used in supermarkets and self-service stores. They have an exposure depth of up to 1 meter and a dynamic cooling system, in which air moves in the workspace by forced convection. This type of refrigeration equipment requires special professional installation - connection to a remote refrigeration unit or to a centralized refrigeration system. Unlike refrigerated display cases with a built-in refrigeration unit, such counters have a much more uniform temperature field along the exposure depth (the difference is within 1-1.5 ° C).
Refrigerated counters can be made in several climatic classes.
Showcases with a built-in refrigeration unit are usually produced in two climatic classes: the third (refrigerated showcases operating at an ambient temperature of no more than 28 ° C and relative humidity - up to 60%), and the fourth (temperature - up to 32 ° C and humidity - up to 55% ).
As for refrigeration counters with a remote unit, then, accordingly, either a conventional refrigeration unit or a reinforced refrigeration unit (for a tropical climate) is used for cooling the same counter.
The body of the refrigerated display case consists of two sheets of metal, between which polyurethane foam is poured, which has high thermal insulation properties. There is a refrigeration unit at the bottom of the display case. The evaporator is mounted on the back wall of the case, and sometimes at the bottom of the showcase in counters under the external cold. In most models of refrigerated display cases with a built-in unit, there is a hidden chamber for storing merchandise, located under the display surface, which is very convenient.
The shape of the front glass can be straight or curved. In the upper part of the glazed refrigerated display case there is a fluorescent lamp with one or two rows of lamps. It is also possible to illuminate a part of the counter from the floor to the glazed part. On the seller's side, there is a work surface that can be made of laminated board, stainless steel or stone.
When choosing a refrigerated display case, you should pay attention that the countertops are made of stainless steel. It is important that only food-grade aluminum is used for the interior decoration. It is also necessary that the pallets are made of stainless steel. It is convenient if the design of the pallets excludes the flow of defrosting products into the bath, and when there are additional compartments for storing goods. In addition, make sure that it is possible to install refrigerated display cases in a single line of display cases.
Refrigerated slides
Another common name for this type of refrigeration equipment is regal. Refrigerated slide (wall refrigerated display case) is a refrigerated rack.
There are specialized types of slides for each product.
"Grocery store" (cheeses, sausages, milk). Standard design: 4 - 5 shelves, adjustable in height and tilt, temperature mode - fan, 0 ... + 5 ° С.
"Vegetables fruits". Standard version: inclined mirror, 2-3 shelves, adjustable in height and tilt, temperature regime - fan, 0 ... + 7 ° С.
Meat (fish and meat delicacies, chilled meat). Standard design: inclined mirror, 2-3 shelves, adjustable in height and tilt, temperature mode - fan-cooled -1 ... + 3 ° С.
"Discount" - allows you to load goods on pallets.
Corner slides. Slides in the corner version appeared on the market of commercial equipment.
There are also slides for external cold and slides with built-in units.
For slides with a portable unit, the height of the base is 30-40 cm. The low base provides a better view, demonstration of the goods, the slide seems to recede into the background, bringing the goods to the fore.
Slides with a built-in unit have a plinth height, as a rule, from 50 cm and more, which makes it visually cumbersome. Accordingly, both in terms of display area and product presentation, it is inferior to a slide with a low base. How less height the base, the higher the cost of the slide.
The height of the slides ranges from 200-225 cm. As practice shows, optimal height the location of the upper shelf is not higher than 170 cm. Accordingly, it is quite enough if the overall height of the slide is 200 cm - this is optimal both in terms of price and functionality. But if the store is positioned in the price category above the average or as an elite one, then it is recommended to use slides with a height of 220-225 cm.In addition to the possibility of installing an additional shelf (for tall customers), such a slide looks much more spectacular, besides, the adjacent metal wall racks with frieze will look better in a single line with slides of a similar height.
The depth of the slide ranges from 100 to 110 cm. In this case, it all depends on the chosen store format and the availability of warehouse space. The most convenient depth for the buyer is 100 cm, because there is no need to "go deep" too much by looking inside. In addition, retail space is saved. Naturally, at a given depth, sellers will have to report the goods more often. For discounters, economy stores, shops for wholesalers, as well as with limited storage space, it is recommended to use slides with a depth of 110 cm, which allows you to display goods in packaging.
Refrigerated cabinets
Refrigerated cabinets are designed for storing and displaying products in shops and catering establishments.
According to storage temperatures, refrigeration cabinets are divided into 4 groups: medium-temperature, low-temperature, freezing for ("shock / shock freezing") and combined refrigerating and freezing.
Medium-temperature cabinets are used for short-term storage at temperatures from -3 to + 10C of pre-cooled perishable products.
In most models of medium temperature cabinets, only positive storage temperatures are provided. Therefore, they are not suitable for long-term storage of products under conditions of freshness. Cabinets with positive temperature conditions are used for gastronomic products, drinks, confectionery, fruits and vegetables.
Low-temperature (freezing) cabinets are designed for storage and sale of frozen foods and semi-finished products. Different models can have different operating temperatures (up to -24C), depending on the purpose of the cabinet and the manufacturer's brand. Equipment with operating temperatures above -18C is not suitable for long-term storage of frozen foods.
Fast cooling and freezing cabinets are used in catering establishments when preparing a large number of dishes at banquets.
Combined cabinets with two insulated chambers are designed for storing fresh and frozen food. Storage temperatures for pre-chilled food from -2 to +8 C, frozen from -18 to -22C.
The combination cabinet takes up less space in the room than two separate cabinets with the same volume for storing chilled and frozen food.
Refrigerated cabinets can vary in volume: small cabinets up to 100 liters, medium cabinets up to 700 liters, as well as large cabinets from 700 to 1400 liters.
Refrigerators differ in the material of the body. It can be stainless steel or painted galvanized steel. A stainless case is usually justified in catering establishments, and in trade, cheaper white refrigerated cabinets are mainly used.
Refrigerators can also differ in door design.
They can be hinged or coupe. Sliding doors are relevant for the ergonomics of retail outlets.
Refrigerator cabinet doors can be glass or blind. Models with transparent doors and bright illumination are intended for demonstration and sale of products, and also serve as a decoration of the retail space. Models with blind doors are cheaper in price.
Refrigerating chambers can be one or two doors.
Refrigeration cabinet doors can be positioned vertically or horizontally. When positioned horizontally, the doors can be opened like in a swing cabinet or moved like in a compartment.
On many models, door closers are installed, it is possible to change the direction of door opening and locking with a key.
Refrigeration cabinets accessory kits include adjustable shelves (differ in materials and design), hangers, trays, gastronorm containers different sizes and other accessories. Shelves can be installed horizontally or at an angle. Sloped shelves are preferred for storing bottled drinks.
The number of accessories depends on the comfort class and the size of the cabinets.
In recent years for the Russian consumer refrigeration technology and equipment, the latest developments of foreign firms have become available. In addition, domestic manufacturing plants began to master progressive technological solutions. The result was the saturation of the Russian market of commercial refrigeration equipment, renewal of the range and improvement of the quality of domestically produced equipment. In this situation, it is important to correctly determine the need for equipment that is adequate to the needs of the commercial enterprise, taking into account the storage modes, refrigerated capacity and design.
In Moscow alone, about 100 companies are engaged in the sale of commercial refrigeration equipment, and each of them employs from 10 to 50 managers. Many of them have no special education and, therefore, cannot conduct business in a sufficiently qualified manner. Firms are in dire need of a new type of specialists who are well versed in commercial work, trade and technological processes, marketing and advertising activities, management fundamentals, labor protection and safety and, most importantly, the subject of labor - commercial refrigeration equipment.
The growing demand for refrigeration equipment is driven by the growth in the production of chilled and frozen foods.
There is much more refrigerated food than frozen food. Most developed countries consumption of chilled products (by weight) is 10 times higher than that of frozen ones, despite the fact that the cost of the former is almost 5 times higher than that of the latter. The demand for chilled ready-to-eat foods is especially growing.
The annual consumption of frozen food in Western European countries is from 18 to 23 kg, in the USA - 55 kg, the consumption of frozen food has increased from 17.8 million to 30 million tons.
New style life forces people to make complex purchases only 1-2 times a week. Therefore, in order to meet the needs of buyers for fresh products, it is necessary to increase the efficiency of all links of the cold chain: refrigerators, refrigerated vehicles, commercial refrigerated display cases, etc. appearance, but also provides long-term storage in order to create a sufficient stock of goods, as well as seasonal goods.
To ensure the good quality of food products, they are preserved with the use of cold, that is, they are stored at low temperatures from harvesting and production to consumption. In the trading network, frozen or chilled products are delivered by specialized transport, stocks are stored in the refrigerated chambers of the store. In sales areas, products are in refrigerated display cases, chests, counters, display counters, refrigerated cabinets.
In a market economy, high-quality commercial refrigeration equipment is of great importance. One of the main factors in increasing consumer demand is the expansion of the range of products, the good quality of which is ensured only with proper storage and adherence to the temperature regime. In addition, when purchasing a large batch of products, an enterprise can receive significant discounts on goods, and high-quality storage of a large amount of products can only be ensured through good refrigeration equipment.
One of the main directions in domestic production refrigeration equipment today is the creation of its parametric series with filling thermal insulation, forced air circulation and a single module.
The unification of equipment in terms of temperature parameters, units and sizes provides a decrease in energy consumption, material and metal consumption of machines, increases the operational reliability and the efficiency of the equipment volume. It also makes it possible to significantly reduce the number of standard sizes of products that are identical in functional purpose, and to create, on the basis of one initial model, a number of single-functional types of refrigeration equipment with different operational and technical and economic parameters. Prefabricated refrigerating chambers are used in small trade enterprises where it is impractical to use stationary cameras, as well as in self-service stores for the sale of goods from packaging equipment and for daytime storage of products in order to replenish them as they are sold from counters and showcases in sales areas.
