Difference Between Low Temperature Explosion-Proof Fridges and Traditional Explosion-Proof Fridges - Shanghai Explosion-Proof Refrigerators

Explosion-proof refrigerators, also known as explosion-proof coolers, feature all copper coil evaporator tubes, processed into wide, irregular stainless steel plates for a smooth surface and even thickness. This not only ensures their longevity but also provides a flat and sturdy appearance for the coolers. Copper tubes offer superior cooling efficiency and corrosion resistance compared to aluminum or composite tubes. The copper coil design boasts high internal cleanliness and fewer tube joints, preventing internal leaks or blockages in the refrigeration system. By converting the circular tubes into rectangles, the contact between the evaporator tubes and the cooling inner lining shifts from point contact to surface contact, thereby increasing the surface area and accelerating the cooling process.

Traditional explosion-proof freezers simply keep items in a low-temperature environment during the freezing process, as lower temperatures are unsuitable for bacterial growth, ensuring that the items do not spoil. However, the nutrient fluid, specifically water, inside the cell walls forms ice needles, which can penetrate the cell walls over extended freezing periods, causing the water to escape. Consequently, traditional explosion-proof freezers may develop a thick layer of frost on the surface of items after a period of freezing, and on the inner lining of the freezers themselves. Regular cleaning is required.

The low-temperature explosion-proof refrigerator freezing process involves the rapid crossing of the ice crystal zone by the nutrient fluid, or water, within each cell. This water then quickly forms tiny ice crystals within the cell walls. These tiny ice crystals are not as sharp and are stored within the cell walls, ensuring the cell's vitality. Therefore, as long as the item is stored within the appropriate low-temperature storage range, prolonged freezing will maintain excellent freshness.

The intuitive method is that traditional explosion-proof refrigerators need to defrost about once a month, and items often develop frost on their surfaces. The inner walls of explosion-proof freezers can also accumulate thick frost, which is moisture from the items' cells that condenses into frost upon contact with cold air. In contrast, the freezing process in low-temperature explosion-proof freezers requires no defrosting for six months, as the nutrients within the cell walls of stored items are "locked" in place. The freezing process does not release moisture. Therefore, low-temperature explosion-proof freezing reduces frost accumulation by 80% compared to traditional explosion-proof refrigerators, and the principle lies here.

Why do the items frozen in explosion-proof low-temperature refrigerators not exude bloodwater upon defrosting? Traditional explosion-proof freezers destroy the cell walls of the ingredients after a period of freezing, resulting in bloodwater leakage and nutrient loss upon defrosting. However, the items stored in explosion-proof low-temperature storage retain their nutrients within the cell walls. After defrosting, there is no bloodwater exuded, and the items maintain their brightness, elasticity, and original freshness.
