Precautions for the use and maintenance of quick-freezing cold storage: 1. Prevent the freezing and thawing cycle, freezing and freezing of the building structure. 2. Protect the floor from frost and damage. 3. In the use of quick-freezing warehouses, the freezing and refrigerating capacity should be brought into full play in accordance with the design requirements, ensuring safe production and product quality, and maintaining the cold-storage building structure. The warehouse should set up a special team to manage, and the responsibility should be implemented by everyone, every warehouse door, every piece of equipment and tools.
Attentions for the installation of quick-freezing cold storage: 1. The foundation of the quick-freezing cold storage is affected by low temperature, and the moisture in the soil is easily frozen. Due to the volume expansion of the soil after freezing, it will cause ground rupture and deformation of the entire building structure, which will seriously make the cold storage unusable. For this reason, in addition to an effective heat insulation layer, the floor of the quick freezing cold storage must be treated under the heat insulation layer to prevent the soil from freezing. 2. The installation of quick-freezing cold storage uses stainless steel plate, embossed aluminum plate, colored steel plate, and composite plastic steel plate as the panel, rigid polyurethane foam plastic as the insulation material, and the composite wall panel is made by advanced technology. Good performance, corrosion resistance, anti-aging and moth-proofing, non-toxic, non-mildew, it can show its superiority when used at lower temperature. The inner and outer panels of the board are made of colored steel (the base material is galvanized steel). The core of the board is foamed rigid polyurethane or pasted polystyrene foam board. Since all components except the ground are
How to distinguish between various cold storages: According to the different products that are placed, we generally divide the cold storages into the following types: 1. The storage temperature of the fresh storage is generally 0 ℃ ~ 5 ℃, which is mainly used for fresh storage That is, to maintain the original quality and freshness of agricultural products to a maximum extent for a long time, and the living body of agricultural products should not die as much as possible, and the cells are in a dormant state during the refrigeration process, reducing the loss of nutrition and maintaining the fresh quality. This is generally used in fruits and vegetables.
What is a freezer? Quick-freezing cold storage refers to a method of quickly freezing food through its maximum ice crystal generation area and quickly freezing when the average temperature reaches -18 ° C. The temperature of the freezer is generally -15 ° C to -35 ° C. Mainly used for low-temperature fast freezing of food, medicine, medicinal materials, chemical raw materials and other items. With fast cooling, good freshness and so on. The so-called rapid freezing refers to the method of quickly freezing food when it passes through its largest ice crystal generation area and when the average temperature reaches -18 ° C.
