Small combined cold storage

The following is an example of description based on common cold storage types and their applicable temperature ranges:

1. Fresh-keeping storage: The temperature is usually controlled between 0℃ and 5℃. This cold storage is mainly used to maintain the freshness of foods such as fresh meat, dairy products, fresh eggs, fruits and vegetables. Within this temperature range, the nutritional consumption of food is slowed down, and the growth of microorganisms is also inhibited49.

2. Refrigerated storage: The temperature is generally set at -10℃ to -18℃. It is suitable for storing foods such as meat and aquatic products that need to be stored for a long time. At this temperature, the shelf life of food can be greatly extended410.

3. Quick-freezing storage: The storage temperature is usually set below -30℃. This cold storage is mainly used to quickly freeze foods, such as quick-frozen meat, quick-frozen dumplings, quick-frozen vegetables, etc. Quick freezing can better maintain the taste and nutritional value of food410.

4. Low-temperature storage: The temperature is generally controlled at -22℃ to -25℃. It is mainly used to store temperature-sensitive foods such as ice cream and seafood. Within this temperature range, the taste and quality of these foods can be ensured410.

5. Ultra-low temperature storage: The temperature is usually below -40~-60℃. This cold storage is suitable for special purposes, such as industrial, medical, tuna storage and other fields with high requirements.

The insulation board uses polyurethane rigid foam, which is currently recognized as the best building thermal material internationally. It has low thermal conductivity, good load resistance, high bending strength, no water absorption, no rot, no insect bites, good flame retardancy, and a wide temperature range. Our company introduced an Italian continuous production line, using the physical properties and unique formula of polyurethane (PU.PIR) to evenly spray the polyurethane foaming agent on the color-coated steel plate, so that the foaming agent foams between the color-coated steel plates to form a three-layer one-time formed polyurethane (PU.PIR) color steel composite sandwich panel. This new light building material is a perfect combination of color-coated steel plates and polyurethane, and is the development direction of light building materials.
