Understand the Low Temperature Preservation Principle of Refrigerated Truck

  • Author:Chang Jie

The refrigerated trucks are mainly used for the transportation of fresh meat, vegetables and seafood. The refrigerated vehicles are assembled by assembling technology. The
plastic panels are made of all-plastic composite board. The inner and outer panels are made of high-quality glass steel or alloy rust-proof aluminum plate, stainless steel plate. Laminated polyurethane foam insulation materials, the plates with high-strength adhesive between the pieces, together with the aluminum alloy riveting into the overall profile. Enclosure and the door to install anti-low temperature insulation seal, the door lock structure of the international Van stainless steel standard parts, car plate seamless, smooth appearance, easy to clean, impact resistance, corrosion resistance. Cold storage of cold storage is how the principle of it?
 
Aquatic products spoilage of the main reasons is the aquatic products itself or with the process of storage and transportation of contaminated microorganisms, in the appropriate
conditions of growth and reproduction, decomposition of fish protein, amino acids, fats and other ingredients have different odor and toxic substances, Resulting in spoilage of
aquatic products; the other hand, the aquatic products contain enzymes in certain environmental conditions can promote the corruption of fish deterioration. In the refrigerated trucks storage and transportation process, to ensure the quality of aquatic products to achieve the purpose of preservation, we must control these two factors.
 
Environmental temperature and moisture conditions and microbial growth and reproduction are closely related. Moisture is essential for life activities of microbial substances, is the basic component of the body composition of aquatic products in the more water, the more the bacteria more easily. Generally believed that more than 50% moisture, bacteria can grow and multiply; moisture below 30%, bacterial growth began to be inhibited; water below 12%, the bacteria on the difficult breeding.
 
Temperature is an important condition for microbial growth and reproduction of various microorganisms suitable growth temperature is different, more than its optimum growth
temperature range, it will stop the growth or death. The role of enzymes and temperature are also closely related. At 37 ℃, undergraduate decomposition of the strongest, the fastest chemical reaction. As the temperature increases, the decomposition ability of the undergraduate, when the temperature exceeds a certain range, the enzyme began to be
destroyed. So reduce the temperature to stop the breeding of micro-organisms, and even death, so that reduced or loss of enzymatic decomposition, can extend the fresh aquatic
products.The refrigerated trucks are mainly used for the transportation of fresh meat, vegetables and seafood. The refrigerated vehicles are assembled by assembling technology. The plastic panels are made of all-plastic composite board. The inner and outer panels are made of high-quality glass steel or alloy rust-proof aluminum plate, stainless steel plate. Laminated polyurethane foam insulation materials, the plates with high-strength adhesive between the pieces, together with the aluminum alloy riveting into the overall profile. Enclosure and the door to install anti-low temperature insulation seal, the door lock structure of the international Van stainless steel standard parts, car plate seamless, smooth appearance, easy to clean, impact resistance, corrosion resistance.
