Vacuum pre-cooling:
1. Retain freshness and nutrition;
2. Prolong preservation time and shelf-life;
3. Fast cooling speed and uniform cooling, normal 20 to 30 minutes cooling duration for each cycle;

Working Principle of Vacuum Pre-cooling:
The product is placed in a vacuum so that the atmospheric pressure around the product is reduced. This reduces the water vapor pressure around the product, and when the pressure is lowered below that inside of the product, water evaporates from the product. This in turn lowers the surface temperature of the product.
