Product Description

Liquid nitrogen temperatures can reach minus -190ºC. When it is in contact with food, gasification will be able to take heat away more quickly. The ultra-low temperature and high heat exchange rate achieve a really quick frozen. Such rapid freezing, generating the smallest ice crystals, helps maintain food texture. This also prevents water loss, ensuring almost no loss of original color, flavor, and quality. These vaporized refrigerant nitrogen is directed to the front end of the refrigerating machine uniformly, completing the exchange of hot inverse, thereby improving the utilization of the nitrogen.

Liquid nitrogen quick freezing machine is suitable for food with high value, such as cooked wheaten food, fish, shrimp, roe, abalone, and more.

Frequently Asked Questions

What is the lowest temperature the liquid nitrogen freezer can reach?
The liquid nitrogen freezer can reach ultra-low temperatures as low as -190ºC, allowing for extremely rapid freezing.
How does liquid nitrogen freezing preserve food quality?
Because of the rapid freezing rate, it generates the smallest possible ice crystals, which prevents damage to the food's cell structure and maintains original texture, flavor, and color.
What materials are used for the freezer construction?
The entire structure of our tunnel freezer is built using high-quality SUS304 stainless steel for maximum hygiene and durability.
Is the freezing time adjustable?
Yes, the tunnel cycle time is fully adjustable, typically ranging from 8 to 40 minutes depending on the product requirements.
What types of products are best suited for this equipment?
It is ideal for high-value foods such as seafood (shrimp, fish, abalone, roe) and cooked wheaten products where quality preservation is critical.
Is special technical training required to operate the machine?
No, the liquid nitrogen freezer is designed for easy operation and repair, meaning no specialized technician is required for daily use.
