Guangdong Abalone Liquid Nitrogen Freezing Machine Price ZDYT-SDX-2

Description :

　　Quick freezing mechanism of cabinet liquid nitrogen freezer

　　1. Fast speed and high efficiency

　　Using liquid nitrogen with a boiling point of -195.8 ℃ as the refrigerant, the boiling point is much lower than that of ammonia (-33 ℃) and Freon (-30~-40 ℃). Due to the intense heat exchange between liquid nitrogen and food at a temperature difference of over 200 ℃, the freezing speed is extremely fast, with a temperature drop of about 7-15 ℃ per minute. The freezing speed is about 30-40 times faster than general freezing methods. The corresponding hourly freezing rate has significantly increased.

　　2. High quality

　　Due to the extremely fast freezing process, food that has been frozen by our body can maintain its original color, aroma, taste, and nutritional value to the fullest extent possible. Reduce moisture loss, low loss, without reducing weight. The time for generating ice crystal bands is within about 3-9 minutes, while ordinary freezing requires more than 90 minutes

　　Due to the ability of chao quick freezing to freeze the colloidal bound water and free water in cells, as well as the free water in intercellular spaces, into countless fine and uniform ice crystals, the cellular tissue is not damaged. Therefore, after thawing, the food can be restored to its original fresh state and nutritional components to a limited extent.

　　3. Low dry consumption

　　The dry consumption of frozen food is low. The dry consumption rate of food frozen with traditional freezing devices is between about 3% and 6%, while freezing with liquid nitrogen freezing devices can reduce it to about 0.25% to 0.5%, which is particularly important for higher priced food.

　　4. Antioxidant and less bacteria

　　When liquid nitrogen is used for quick freezing, the gas produced is inert nitrogen gas, so the food will not be oxidized, spoiled, or discolored during the freezing process, and it can protect the aroma of pre made food when it is first made. Due to the fact that frozen food reaches -10 ℃ instantly, there are fewer miscellaneous bacteria in the frozen product.

　　5. Easy to operate

　　Human computer interface+PLC automatic program control system+module programmable control, one click operation, easy to learn and extremely convenient.

　　6. Low maintenance costs

　　The equipment requires less one-time investment, has low operating costs, is easy to implement mechanization and automation assembly lines, and improves productivity. Moreover, it occupies a relatively small area, which effectively saves on factory rental costs.

　　7. Low power consumption

　　This device mainly relies on liquid nitrogen phase change refrigeration and internal energy conversion to achieve the purpose of quick freezing and preservation. Unlike ordinary refrigeration systems, which require a large amount of electrical energy to drive the refrigeration machinery during freezing, it does not require direct consumption of electrical energy from the refrigeration principle, only a very small amount of electricity is needed to start the equipment.

　　8. The equipment structure is simple, safe and reliable

　　The device has a simple structure, can work continuously for 24 hours, and has a long service life. Effective design can reduce the consumption of liquid nitrogen. Analysis shows that the only moving parts of the entire device are the conveyor belt's moving mechanism and a simple axial flow fan, unlike ordinary refrigeration systems with complex structures and multiple mechanical moving parts, which reduces the possibility of malfunctions. Moreover, the system has low working pressure and no high-pressure equipment.
