With the rapid development of the food industry, preserving food freshness is crucial, regardless of whether it is the pre-packaged food industry or the traditional packaging food industry. Lowering the temperature is one of the main ways to preserve food, and TRIPU has developed two types of tunnel quick-freezing machines for food quick-freezing and preservation: fluorine refrigerant tunnel quick-freezing machine and liquid nitrogen tunnel quick-freezing machine. Both products have high efficiency and stability in rapid cooling and preservation of food. However, there are many differences between the two products, and we need to choose the appropriate product according to existing production processes.
The liquid nitrogen tunnel quick-freezing machine is widely used in the industry for high-end food products. It has the characteristics of short freezing time and high frozen product quality due to the ultra-low temperature characteristics of liquid nitrogen. And because of this, the cell membrane will not be destroyed, thus retaining the best taste and texture. In addition, it has the advantages of low noise, simple structure, small footprint, and low equipment cost. However, it requires continuous replenishment of liquid nitrogen, and the high price of liquid nitrogen is its main disadvantage.
Compared with the liquid nitrogen unit, the fluorine refrigerant unit mainly differs in that it does not need to replenish refrigerant for a long time. It only uses the energy consumption cost of the equipment itself in operating costs. From the perspective of long-term use, the subsequent use cost of the fluorine refrigerant unit is much lower than that of the liquid nitrogen unit. However, its equipment cost is high, and it takes up a lot of space. Also, it damages the food cell membrane, causing the taste not to be as good as the liquid nitrogen unit. Additionally, it also has a longer freezing time than the liquid nitrogen unit, and after continuous work, it needs to stop for a certain period of defrosting, which is also a major disadvantage.
