Features
WHAT IS A LIQUID NITROGEN FREEZER?
Simply put, a nitrogen freezer is just a freezer which can freeze products rapidly with very low temperature (0℃ to -196℃). 

Liquid nitrogen freezer is a kind of blast or shock freezers that uses liquid nitrogen (LN2) as the cryogen to freeze large quantities of goods very quickly. When liquid nitrogen (LN2) vaporizes or gasifies, it absorbs the heat of the processed goods efficiently and instantly. The vaporizing-spraying system pushes the vaporized nitrogen all around the goods directly with a high velocity, to reduce the temperature of products as quickly as possible.
WHY USE A LIQUID NITROGEN FREEZER?
Nitrogen is a kind of toxic-free cryogen, poisonless and harmless. The vaporizing process of liquid nitrogen itself absorbs heat rapidly, no need condenser or compressor as those conventional freezers do. It is totally safe and environment-friendly. Utilizes a minimum amount of floor space and electricity. 

When you freeze foodstuffs, the water inside crystallizes into ice. The longer the freezing process takes, the larger the ice crystals. Larger ice crystals damage materials by causing phenomena like cell bursting (as shown in the picture below), which affects quality and flavor of foods.

The freezing speed of liquid nitrogen freezer is three times faster than conventional quick-frozen equipment. Rapid freezing causes the crystals formed to be very small, which does less damage and preserves food at a higher quality. Even more usefully, once the food is "quick frozen" it can be moved into a normal freezer for longer term storage.
Size of ice crystals formed by quick-freezing freezer and conventional freezers
Ice crystals formed by quick-freezing freezer are small, even and regular, they hardly damage the cell structures. While those ice crystals formed by conventional freezer are large which caused serious damanges to cell structures of food.
This is the key reason why liquid nitrogen quick freezers bring extended food safety and quality!
WHAT ARE THE BENEFITS?
Liquid Nitrogen Quick Freezing is a method widely used in frozen food industry for things like meat, poultry, prepared foods, fruits, vegetables, beverages or aquatic products, etc. Many commercial kitchens also use liquid nitrogen chilling and freezing technology to store foodstuffs.

One of the most important benefits a liquid nitrogen quick freezer brings is locking in freshness of produce. Our solutions allow companies to keep food fresh for months at a time before it is no longer suitable for consumption. This is because it slows down the natural decaying process and inhibits bacterial activities that happens in all meats, fish,
poultry, fruits and vegetables.

Liquid nitrogen blast freezing technique can be used to preserve essential nutrients found in food, making your produce fresher and healthier.
Wide Suitability
0℃ to -196℃ working temperature, freely regulated, 1℃ to 2℃ control precison, fit different kinds of food.
Improved Productivity
Freezing speed is 3 times faster than conventional freezers. Product center temperature reaches -18℃ quickly.
Save Labor Costs
Optimized mechanical structure makes it easier to be operated, easy to clean and maintain, save labor and time costs.
Maintain Original Texture and flavor
0.25% ~ 0.5% low drip loss, instant freezing, preserve original appearance, color, flavor and nutrition of the processed products.
Safe and Environment-Friendly
Nitrogen is toxic-free, poisonless and harmless to food, human and the environment. No pollution gas exhausts.
Low Noise Emission
No condensor or compressor, small energy consumption, high reliability and performance, low operation noises.
Widely Used in Food Industries
As a proven technology, liquid nitrogen freezers are widely applied to aquatic products, bakery products, meat, poultry, fruits, vetegables, etc.
Improved Food Safety
Overall body of the equipment is made of SUS304 stainless steel. Nitrogen is non-toxic, poisonless and harmless.
Utilizes Minimum Amount of Floor Space
The sizes of liquid nitrogen cryogenic freezers are much smaller comparing with conventional freezers, utilizes a minimum amount of floor space, easy to install and set up.
Extended Shelf Life and Profitability
Liquid nitrogen flash freezers perfectly maintain the original texture, color and flavor of food, no damages to cell structures. Processed food have longer shelf-life and better quality.

How to replace the components and parts?
A2
Videos, documents and remote video are available that teach clients how to replace.
Q3
How should know what freezing time or temperature is suitable for my products?
A3
Suitable Freezing time and temperature depends on specific kind of food, here are some tested data:
- Normal Aquatic Products: 2cm to 5cm thick, set temperature -60℃ to -120℃, 15 to 20 minutes
- Trepang and Crap: generally set -60℃, and store temperature below -18℃
- Meat and Poultry: freeze at -100℃ to -120℃, 20 to 30 minutes, store temperature below -18℃
- Durian: freeze temperature at -100℃ to -120℃, 60 to 80 minutes
