What is the difference between air-cooled fresh-keeping cabinet and fresh-keeping cabinet
2024-03-28
1. Air-cooled fresh-keeping cabinet
The air-cooled fresh meat cabinet has the advantages of fast freezing speed, automatic defrosting system, strong food preservation ability and good temperature uniformity. However, the power consumption is large, the noise is high, and the price is also high.
The fresh meat cabinet using air-cooled technology does not need to be defrosted, clean and fresh, and the air-conditioning is forced into the space in the box by the air duct, resulting in circulation and uniform temperature. The automatic defrosting of the freezer compartment has low humidity, uniform cooling to achieve the effect of temperature control, and the food will not freeze together, which greatly reduces the phenomenon of mutual odor. Its shortcomings lie in the high cost of air cooling technology and high power consumption; food is easy to dry and dehydrated, suitable for use in humid areas. The power consumption of the air-cooled fresh-keeping cabinet is higher than that of the direct-cooled fresh-keeping cabinet, and the effective volume is small under the same volume. At present, the air-cooled fresh meat cabinet is mainly in the United States, Japan, South Korea and China's southern market.
2. Straight chilled meat cabinet
The natural convection of the low temperature on the surface of the evaporator reduces the temperature in the box, but the temperature is uneven. More power saving, the same volume, the effective volume is large. The advantages of direct cooling technology are low manufacturing cost, good preservation effect and low power consumption, but non-drawer freezer sometimes requires manual defrosting.
Direct cooling fresh-keeping cabinet has low power consumption, low noise, low price, and preservation of refrigerated food; slow speed and poor temperature uniformity.
