Freeze-drying Advantages
 

The freeze-drying process has many advantages. Freeze-drying preserves product quality by removing water from the product, which inhibits bacteria and microbial growth. Freeze-drying also helps retain flavor, texture, and color, as well as the nutritional content of food products. Freeze-drying also helps preserve shelf life of products and helps to reduce shipping costs due to its low weight and volume. Freeze-dried products, due to their stability, can also be easily stored and transported.
 
Freeze-drying Principle
 

Freeze-drying is a physical drying method in which the water in the material is directly converted into ice at extremely low temperature, thus drying. The main process of freeze-drying is to directly convert the high-temperature water molecules into low-temperature ice molecules, that is, directly convert the water molecules into gaseous state, thus avoiding the transformation process of water from liquid to gas in the traditional drying method, thus greatly reducing the content of water in the material.
