                What is a crayfish quick-freezing tunnel?


                The crayfish quick-freezing tunnel is a large-scale quick-freezing machine suitable for large-scale processing and production of the production line. It has strong quick freezing ability; it is easy to operate and has high automation. Applicable to large-scale, continuous, less humanized and large-scale industrial crayfish production mode, can be combined with other food lines to become an automatic line, in addition to quick-freezing tunnels with large quick-freezing capacity, the company also has small and medium-sized production. Cabinet type liquid nitrogen quick freezing machine.


                What are the benefits of using a crayfish quick-freezing tunnel?

                The crayfish quick-freezing tunnel is used to quickly freeze the crayfish, which has higher production efficiency per unit time and quicker freezing ability. The operation is simple and the degree of automation is high. It is suitable for use in basic foodstuffs and standardized foodstuffs. It is superior to traditional freezing methods, does not damage cell walls, does not lose tissue fluid, and maintains the original color, original flavor and original quality of food.


                The quick freezing speed is extremely fast and the effect is excellent:


                Due to the type, size and thickness of crayfish, the general quick freezing time is within 5 minutes to 30 minutes. The quick freezing time is extremely fast, which reduces the dehydration and dry loss of food, and improves the texture, color and flavor of frozen food;


                Short freezing time and high output:


                The freezing speed is extremely fast, and the temperature is lowered by 7 to 15 ° C per minute, and the freezing speed is 30 to 40 times faster than the general freezing method.


                Low temperature sterilization, effectively inhibiting microbial growth:


                The gas produced during quick freezing of liquid nitrogen is inert nitrogen, which protects the food by isolating the air during the production process. At the same time, due to the extremely fast freezing speed, the temperature of the food rapidly drops below the normal growth activity temperature of the microorganism, which advantageously inhibits the growth of microorganisms and its biochemical reaction.


                The quality of crayfish after quick freezing is high:


                Due to the rapid freezing and freezing of liquid nitrogen, the quick freezing time is extremely short, the time for the maximum ice crystal formation zone is less than 5 minutes, and the normal freezing time is more than 190 minutes. Since the rapid freezing does not destroy the cell structure of the crayfish, the water in the cells and the intercellular space can be simultaneously frozen into numerous fine and uniform ice crystals, so that the cell tissue is not damaged, and the food can be restored to the original state after thawing. The fresh state and the original nutrients maintain the original taste and flavor of the food, thus achieving the "original" effect.


                Long shelf life:


                The crayfish that are frozen in the quick-frozen tunnel of crayfish have a shelf life of more than three times that of conventional freezing equipment.


                Safe and environmentally friendly:


                It adopts safe and environmentally friendly quick-freezing medium and quick-freezing method, which is easy to operate and has no safety hazards.


                Small dry consumption:


                Generally, the dry loss rate of freezing is 3 to 6%, and the liquid nitrogen quick freezing can be reduced to 0.25 to 0.5%, which is particularly important for high-priced foods.


                Easy to clean, low maintenance costs:


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


                With the crayfish quick-freezing tunnel production line, you no longer have to worry about the poor quality of the crayfish due to long storage time, the taste is worse, and the original taste is lost!
