The Difference Between Liquid Nitrogen Quick freezer and Traditional Flash Freezer

The main differences between liquid nitrogen quick freezing machines and traditional flash freezing machines lie in cooling media, freezing speed, and application scope. Liquid nitrogen fast freezing machines achieve instant freezing by utilizing low-temperature liquid nitrogen, whereas traditional freezing machines rely on circulating air for cooling.

1. The working principle of liquid nitrogen quick freezing machine

The liquid nitrogen rapid freezing machine utilizes the low-temperature properties of liquid nitrogen to rapidly cool ingredients to extremely low temperatures. With a temperature of -196°C, liquid nitrogen can swiftly freeze food, pharmaceuticals, and other materials in a very short time. The fine and uniform ice crystals formed during the flash freezing process do not damage cells, thereby preserving product quality.

2. Working principle of traditional flash freezing machine

Traditional flash freezing machine uses air flow for cooling. In the freezer, cold air circulates through the fan, taking away the heat from the surface of the item. The temperature of traditional quick freezing machine is usually between -18°C and -40°C, which takes a long time to achieve the desired freezing effect. The freezing process is slow and unevenly cooled, which generally leads to a loss of product quality.

3. Different cooling media

The liquid nitrogen quick freezer from Sichuan Aosituo uses -196°C liquid nitrogen as the cooling medium, while traditional rapid freezer uses air. The extremely low temperature during the liquid nitrogen quick freezing process can more effectively lock in the flavor and nutritional content of food, which the traditional blast freezing machine can not match.

4. Different freezing speed

The liquid nitrogen fast freezer can complete freezing in a few minutes, ensuring that the surface and internal temperature of the product quickly drops to -18°C, which is particularly important for maintaining product quality. In contrast, the freezing process of traditional quick freezing machine may take several hours, and products are easily contaminated by bacteria and microorganisms during this process, which can lead to a decrease in product quality.

6. Different scope of application

Liquid nitrogen fast freezer is widely used in high-end food, scientific research, pharmaceuticals and other fields, suitable for products that require high efficiency and high quality freezing, such as fresh seafood, precious medicinal materials and biological samples. Traditional quick freezing machine is suitable for large-scale and highly consistent food processing, such as bulk commodities such as vegetables and meat.
