Air freezing, also known as natural freezing, is a simple freezing method. This method relies on the air to transfer heat to the frozen product so that the frozen product can be heated and frozen. How quickly the air freezes depends on air velocity, air temperature, and the temperature difference between the food and the air.

Air freezing can be divided into two types: intermittent and continuous.

The pressurized air defrosting device is an iron container filled with compressed air at a pressure of (2-3) x 10pa. The temperature in the container is 15-20°C.

As the pressure increases, the freezing point of the frozen product decreases. Therefore, at the same temperature of the ablation medium, the ablation is simple, the ablation time is shortened, and the quality of the ablation product is better. Start the cooler and the blower to make the cold air enter the container at a speed of 1-2m/s, which means defrosting with a combination of pressure and flow air, and the defrosting speed is further improved.
