Liquid Nitrogen Tunnel Freezer Iqf Quick Freezing Machine Quick Freezing Tunnel

Liquid nitrogen tunnel freezer use liquefied nitrogen (LN2) for continuous cooling and freezing. The conveyor belt moves the product along the tunnel. Controlled injection of low temperature liquefied gas can evaporate instantly and reduce the temperature in the tunnel. The latent heat of evaporation is the main source of cold energy. The turbulence fan spreads the gas in the tunnel in a controlled manner and effectively transfers the cooling to the product surface. The exhaust pipe removes the residual gas.

Specification

Equipment material: Inner and outer are made of SUS304 stainless steel
Power distribution: Distribute according to customer's local voltage situation

Convection circulation:

Enhanced axial fan with high-power fan motor, cooling speed is fast and uniform, with double air lock function at both ends, effectively reducing cold air leakage
Lifting system: Screw lifter, lifting height: 500mm

Electrical control:

Man-machine interface +PLC, easy to operate, intuitive and reliable control, with temperature monitoring and alarm functions, electrical interlock, to ensure the safety of equipment and process operation.

Equipment maintenance:

The long-life and low-consumable design, simple replacement of vulnerable part, excellent maintainability.

Equipment cleaning:

Starting from the inclined bottom plate and central drain of the quick-freezing tunnel, DJL quick freezer is designed to ensure the sanitation and hygiene of the equipment, and easy to clean: All internal parts are made of stainless steel or polyethylene. The modules are full welded connection and be grinded and polished; With the help of the screw lifter, the roof of the tunnel can be lifted vertically to facilitate the full cleaning of the tunnel. There is a drainage outlet at the bottom of the equipment.

Although there are standard model for DJL IQF Nitrogen Tunnel Freezer, customized tunnels can be designed to meet the specific needs of any individual application.

Liquid nitrogen tunnel freezer have many USES. You can handle any product flow that must be continuously cooled, refrigerated or frozen. It is suitable for the industrial production mode of large batch, continuity, fewer people and larger area, it can be combined with other food lines to form an automatic line. Mainly used in food industry. Suitable for high value-added food production line, such as: processing of fish and shrimp, shrimp meat, seafood, aquatic products, fresh products, meat products, high-grade fruits, out-of-season fruits, medicinal materials, etc.

FAQ

1. How fast is DJL liquid nitrogen freezing technology?

DJL reply: There will be differences according to the different thickness and the packaging and different freezing temperature of product, when extreme temperature is used, DJL liquid nitrogen fast freezing speed can freeze naked frozen food with a thickness of 5CM in 3 minutes at the fastest., However, it is more common to freeze naked-food which up to 10CM thick within 10-30 minutes, usually used temperature between -80℃ to -120℃, extreme use of liquid nitrogen immersion, the temperature can reach -196℃.

2. What are the advantages of liquid nitrogen quick freezing compared with the traditional freezers and iqf freezer?

DJL Reply: Before answering this question, it is necessary for us to clarify the standard definition of quick freezing: quick freezing of food is to place the pre-processed food into a low-temperature device, pass through the largest ice crystal formation zone within 30 minutes, and the central temperature drops from 0℃ to Below -5℃, the diameter of the ice crystals formed is less than 100μm, and the center temperature of the food after quick freezing must reach the food freezing technology below -18℃. Due to its fast speed, the cell integrity of liquid nitrogen quick-frozen food was much higher than that of traditional freezing method, and the cell damage rate was nearly 80% less than that of slow-freezing food, so its taste, nutrition and color are much better than slow freezing food, In terms of seafood, DJL liquid nitrogen quick-freezing technology can be comparable to seafood in fresh state after freezing and thawing. Therefore, liquid nitrogen quick-freezing technology can better maintain the color, aroma, flavor and taste of food, and its sales value will also be greatly improved.

3. What is the dry consumption of liquid nitrogen quick freezing?

DJL reply: For seafood naked freezing with high water content, after froze by DJL liquid nitrogen freezing technology, its dry consumption is about 1‰ to 5‰, while the traditional freezing method is generally within 3~5% . If the product with a relatively high unit price, alarge part of the loss of economic value can be avoided by dry consumption weight.
