Application of liquid nitrogen freezer in food industry

Application of liquid nitrogen freezer in food industry

As the development of our living standard, the demand for high quality frozen food is rising day by day. Cryogenic freezing use liquid nitrogen as the refrigeration, makes lower freezing time ( -150C) and fast freezing speed. It is known as the best way to keep the original looks and texture of food. We have about 10 years experience in Cryogenic freezers, we are ready to provide the best IQF solutions for your products.

1. Seafood quick freezing.

Liquid nitrogen freezers are mostly used in seafood quick freezing, like fish, shrimp, crab, squid, oyster, etc. Quick freezing cause less drip loss, and does no damage to the cells. The frozen fish can even come back to alive.

2. Poultry

Poultry factories usually have a huge production, traditional freezer use long time for freezing the products, the efficience is very low. By using liquid nitrogen freezer, the freezing time is much less, and can do up to 50 tons per days.

3. Fruits and vegetable

Fruits like durian, strawberry, mango and other seasonal fruits and vegetables need to be frozen immidiately after harvest, requires large freezing capacity and also quick freezing rate.

4. Cooked products, and french fries and ready meals.

Liquid nitrogen freezer also widely used in cooked products, like lobsters, boiled fish, etc.

Cryogenic technology makes frozen fish taste like fresh ones.

Cryogenic technology makes frozen fish taste like fresh ones.

Fish like tuna, kingfish mostly served as sashimi, freshness is the key. Tuna processors spend much money on freezing and transport the fish. Our client in Australia used to export the kingfish in chilled, which cost a lot of money on the air freight.  Now by using liquid nitrogen freezing, you can have the frozen fish as fresh as chilled ones.

In march, we installed a 1000kg cabinet freezer in Adelaide, Australia. The cabinet freezer has 4 trolleys, suitable for whole fish and fish fillet processing. 

-90C freezing temperature, the whole fish average 6 kg each, can be frozen to -40 C core temperature in 50 minutes. The frozen fish looks very beautiful and no damage to the texture.

How the liquid nitrogen freezer works?

How the liquid nitrogen freezer works?

Liquid nitrogen freezer is a new freezing method,The liquid nitrogen goes into the freezer and atomized into cold gas by fans, the cold gas can take away the heat and freeze the products very quickly. It use no compressor unit, therefore it is simple in struture and saves much power

Where we get liquid nitrogen? 
1. Gas company like Linde, Air liquid, Air products have plants in many countries, they are able to supply many kinds of gas and liquid.

2. Big steel mill and chemical plant. They needs liquid oxygen during production, they may have the air seperation system, in this way, the liquid nitrogen price is very cheap.

3.Why liquid nitrogen freezer is better than mechanical freezer?

1. Less capital investment, no need of much building works and very easy to install.
2. Real quick freezing, and better food quality. Quick freezing cause less drip loss and does no damage to the texture of the seafood, after defrost, it looks and taste as the fresh ones.

3. Easy to maintenance and totally safe. It is very simple in structure, no easy to break down, and no potential risk of fire and explosion.

Cryogenic freezer for sea cucumber quick freezing

Cryogenic (Beijing) Science & Technology Co.,Ltd, was founded in 2008, the pioneer of ultra low temperature liquid nitrogen system in China. Now we have the largest liquid nitrogen freezer workshop in China. We never stop innovation and improvement. which makes us the market leader in the liquid nitrogen freezing system and frozen food machinery industry.

We installed two liquid nitrogen tunnel freezers in Vietnam earlier this month, the freezers now fully running for shrimp quick freezing, you can see the freezing speed is very quick and shrimp after frozen looks beautiful.

1. Ultra low freezing temperature

Liquid nitrogen freezer has the freezing temperature down to -150C, for seafood products, we set the freezing temperature between -90C to -110 C according to the weight, size and core temperature requirements of seafood. 

2.  Low drip loss and preserve the texture

Fish like tuna, kingfish mostly served as sashimi, freshness is the key. Tuna processors spend much money on freezing and transport the fish. Now by using liquid nitrogen freezing, you can have the frozen fish as fresh as chilled ones, saves a lot of money and preserve the original taste and flavor.
Kingfish use liquid nitrogen freezing

3. Energy saving and cost effective

Espacially for lobster, shrimp, tuna and other seasonal products, we need to process them as soon as possible. instead of using hours, liquid nitrogen freezer can process the fish, shrimp only in few minutes, enable you to make big quantity in short time. No compressored unit, saves lot of power consumption. 

4. Safe and environment friendly

Liquid nitrogen is totally green, comes from air meet the HSE requirement and no pollution at all, the set up is also much easier than mechanical freezer.

Why liquid nitrogen freezer is better than mechanical freezer?

Why liquid nitrogen freezer is better than mechanical freezer?

Liquid nitrogen temperatures is -196 °C, it is the most ideal refrigeration medium in the world. When the ultra low temperature nitrogen gas in contact with food, it will take the heat of the food away in only few minutes, quick freezing maximally preserves the moisture and keep the original taste, looks and cells structure of the food. The ice crystal inside is very tiny and even, and will not break the cells after defrost. The weight loss after processing is only 0.5%. Nitrogen gas is colorless, odorless, nontoxic, nonflammable, much safer than Freon and Ammonia, especially it is environment friendly.

1. Capital investment. Liquid nitorgen freezer is simple in structure, only requires a liquid nitrogen tank. mechanical freezer has a complicated system, including compressor, condesor, etc. Requires lots of land space and building works.

2. Food quality. The typical mechanical freezer can reach -38C, cost hours to freeze the food. liquid nitrogen freezer can reach -190C, freezing time is only few minutes. Quick freezing does no damage to the cells, and preserve the flavor and looks.

3. Operation cost. mechanical freezers use a lot of electrcity and requires more labour force. Liquid nitrogen freezer saves power consumption, the main cost is liquid nitrogen. It depends on the bulk price you get from the gas company. In general, teh operation cost is about the same.
