Cold storage has strong stability. Polyurethane foam technology makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is, under the unfavorable local temperature and humidity conditions, the characteristics of the cold storage still do not separate and fall off from the carrier layer and remain stable under normal conditions.

Establish a perfect computer network make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union, the United States and Japan, all members of the food supply chain have the legal responsibility to implement traceability.

Newark.The cold storage construction in the site selection undertakes the circulation of low-temperature goods. Therefore, when selecting the site, priority should be given to the transportation convenience of the cold storage construction site, such as close to roads and railways. At the same time, the location of the cold storage should avoid large pollution sources and direct sunlight, and the construction of the cold storage should have good drainage and ventilation conditions.

Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.

.Step of cold storage design: define the volume of the cold storage warehouse. The size of the cold storage should be based on the design of a large number of agricultural products to be stored for a long time. This volume is calculated based on the essential volume of stored goods accumulated in the cold storage, plus the row to row corridors, the indoor space between the pile and the wall, the ceiling and the gap of the packaging house. After the volume of the cold storage is determined, the length and height width ratio of the cold storage shall be determined. Necessary auxiliary engineering buildings and equipment shall also be considered in the design of cold storage, such as working intermediate, packaging and combing room, special tool warehouse, loading and unloading platform, etc.

Commissioning cold storage. After all parts of the cold storage are installed and connected, the cold storage can be started for cold storage commissioning. According to the needs of customers, adjust the value of the cold storage, the cold storage can reach the predetermined temperature, the cooling speed and the operation of the cold storage are normal, and the cold storage can be delivered for use. The cold storage installation unit shall also provide the cold storage user with training on cold storage use and management knowledge, as well as some after-sales training.

Where do you need to build the refrigerator, the size of the refrigerator or the storage capacity (size, storage capacity, ton, cubic meter, frame, box); What products are stored in the built cold storage? The actual storage temperature, storage time and setting temperature can be indicated by specific regulations; If your cold storage becomes larger, you need to master your individual storage volume, the temperature of goods in and out of the warehouse, the frequency of opening and closing the door, etc. If this is clear, it is the selection of raw materials, such as refrigeration compressors, refrigeration units, thermal insulation materials, coolers, doors, temperatures and other refrigeration equipment.

2. Maintenance of food cold storage. In a position convenient for operation outside the door of the refrigerator room, a main switch for cutting off the power supply of the refrigeration compressor shall be set. This switch shall be able to stop the operation of the refrigeration compressor, and relevant signs shall be set. If the mechanical panel is set in the main room, a button switch shall be added next to each refrigeration compressor.

The function of refrigeration is & amp; amp; amp; ldquo; Low temperature storage & amp; amp; amp; rdquo; Introduction & amp; amp; amp; ldquo; Loop type & amp; amp; amp; ldquo; Cold chain logistics & amp; amp; amp; rdquo;

Polyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII, because the temperature difference inside and outside the board is large, reliably and accurately. Special connectors shall be used for wiring, and power protection shall be provided for the box and each power branch.

The use of large-scale cold storage is naturally very strict in installation and material selection. Therefore, in the face of the above possible situations, we can strictly screen the insulation board materials of cold storage, which can effectively alleviate or solve the above problems. However, at present, there are many fields using cold storage insulation board, so the details of the use environment should be considered for the wood making of many such products in the market.

Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.

There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.

knowledge.The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following 6 points: a low-temperature hall, a closed platform, an electric sliding refrigerated door, an anti-collision flexible seal, and a platform height conditioning equipment (lifting channel) are built to complete & ldquo; Door to door & rdquo; Type loading and unloading operation has become a symbol of modern cold storage.

Balance windows shall be provided for the fabricated controlled atmosphere storage.

The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example the cold storage that only circulates vegetables can only build a fresh-keeping cold storage, while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage it should be determined according to the type, quantity, frequency, cycle, whether to use shelf stacking and so on. For example, for fruits and vegetables packed in cartons, and the size of cold storage construction can be estimated in combination with the storage capacity rate of about 0.5-0.6.

Newark.During installation, the plates shall be handled with care. Rough operation is strictly prohibited. Burrs shall be removed at the cutting opening to prevent scratching the plate surface and workers.

In fact, there are some unique installation skills when installing the cold storage? The cold storage installed according to these skills is often short in both effect and quality, and the specific installation skills of the cold storage will also make some relatively detailed introduction for you in the following article. When installing the cold storage, you should install it from the corner first. Later according to the height of the cold storage, make a hole in the middle of the insulation board behind the angle iron parts

The temperature is too high, the condenser is blocked in the cold storage, the compressor is overloaded, there is a lack of refrigerant, the low pressure is too low, the air intake is too large, and the compressor is stuck.
