tunnel type quick freezing machineit is a common equipment in food processing. according to different cold sources, it can be divided into tunnel compressor quick freezer and tunnel compressor.liquid nitrogen quick freezing machine

let’s briefly introduce the characteristics and applications of these two quick freezers.


tunnel compressor quick freezing machine is a traditional quick freezing equipment that uses a compressor to generate cold air for food freezing. the theoretical temperature of this quick freezer can reach minus 35 degrees.

the freezing time is usually about half an hour. however, the cost of tunnel compressor quick freezing machine is relatively high, and the later operating cost is mainly the electricity bill of the compressor, and the maintenance is relatively expensive.

more troublesome. in addition, the tunnel compressor quick freezer has no preservation effect.


in recent years, tunnel-typeliquid nitrogen quick freezing machinegradually emerged and been widely used in the country. this quick freezer uses liquid nitrogen as a cold source by immersing food in liquid nitrogen.

quick freeze. tunnel typeliquid nitrogen quick freezing machinethe construction cost is relatively low, and the later operating costs are mainly the consumption of liquid nitrogen. the freezing speed of liquid nitrogen quick freezing machine is very fast.

theoretically, it only takes 10-15 minutes to freeze a ton of food, consuming about 0.7 tons of liquid nitrogen. in addition, liquid nitrogen has a preservation effect, so more and more companies are paying attention to liquid nitrogen quick freezing technology.


however, it should be noted that the liquid nitrogen quick freezer requires a large amount of liquid nitrogen during use. therefore, when considering purchasing a liquid nitrogen quick freezer, it is recommended to first understand the local

the price and supply of liquid nitrogen to avoid excessive operating costs in the future.


in general,tunnel type quick freezing machineit is a common equipment in food processing. tunnel compressor quick freezing machine and tunnel type liquid nitrogen quick freezing machine are two common types. tunnel compression

mechanical quick freezers are suitable for traditional quick freezing needs, while tunnel-type liquid nitrogen quick freezers are suitable for food processing scenarios that require quick freezing and preservation. based on actual needs and economic considerations

it is very important for food production companies to select the appropriate quick freezer model.
