What is the crayfish quick-frozen tunnel?

Crawfish quick-freezing tunnel is a large-scale quick-freezing machine suitable for large-scale production line processing, with strong quick-freezing ability, simple operation and high automation. It is suitable for large-scale, continuous, less-populated and large-area industrial crayfish production mode. It can be combined with other food lines to form an automatic line. In addition to quick-freezing tunnels with large quick-freezing capacity, the company also has a cabinet-type liquid nitrogen quick-freezing machine suitable for small and medium-sized production.

What are the benefits of using crayfish quick-frozen tunnels?

The quick-frozen crayfish tunnel is used to freeze the crayfish. The production efficiency is higher and the quick-frozen crayfish is stronger in unit time. Simple operation and high degree of automation. It is suitable for the use of basic and standardized food materials. It is superior to the traditional freezing method. It does not destroy cell wall, lose tissue fluid, and maintain the original color, taste and quality of food.

Quick freezing speed is very fast and the effect is excellent.

Due to the variety, size and thickness of crayfish, the freezing time is usually within 5 minutes to 30 minutes. Quick freezing time reduces the loss of dehydration and drying, and improves the texture, color and flavor of frozen food.

The quick freezing time is short and the yield is high.

the freezing speed is very fast. The freezing speed is 30 to 40 times faster than that of the general freezing method.

Low temperature sterilization can effectively inhibit the growth of microorganisms:

The gas produced by liquid nitrogen quick freezing is Sui nitrogen. Nitrogen isolates air during the production process and plays a role in protecting food. At the same time, because of the rapid freezing speed, the food temperature rapidly drops to the normal growth temperature of microorganisms, which is beneficial to inhibit the growth of microorganisms and their biochemical reactions.

The quality of frozen crayfish is high.

Because of the fast freezing speed of liquid nitrogen, the quick freezing time is very short. The time to pass through the maximum ice crystal formation zone is less than 5 minutes, and the normal freezing time is more than 190 minutes. Because rapid freezing does not destroy the cell structure of crayfish, it can freeze the water in the cell and cell space into numerous fine and uniform ice crystals at the same time, so that the cell tissues can not be destroyed. Therefore, after thawing, the food can be restored to the original fresh state and the original nutritional ingredients to the maximum extent, maintain the original taste and flavor of the food, so as to achieve the effect of "original taste of the juice".

Long shelf life:

The shelf life of the crayfish frozen in the tunnel is more than three times as long as that of the traditional freezing equipment.

Safety and environmental protection:

It adopts safe and environmental protection quick-freezing medium and quick-freezing mode, which is easy to operate and has no potential safety hazards.

Dry consumption is small:

Generally, the loss rate of freezing is 3-6%, while liquid nitrogen quick-freezing can be reduced to 0.25-0.5%. This is particularly important for food with higher prices.

Easy to clean and low maintenance cost:

Convenient cleaning to every corner; parts failure rate is very low, greatly reducing maintenance costs.

With the production line of crayfish quick-frozen tunnel, you no longer need to worry about the quality of crayfish is poor due to long storage time, bad taste and loss of original delicacy!
