Industrial Meat Dryer Freeze Dryer Machine
01 What is a freeze-drying machine?
Freeze-drying is a technology that uses the principle of sublimation to dry. It is a process in which the dried substance is quickly frozen at a low temperature, and then in an appropriate vacuum environment, the frozen water molecules directly sublimate into water vapor escape. The product obtained from freeze-drying is called freeze-drying, which is called freeze-drying. The substance is always in a low temperature (frozen state) before drying, and the ice crystals are evenly distributed in the substance, and the sublimation process will not be concentrated due to dehydration, avoiding the side effects such as foam and oxidation caused by water vapor. The dry material is a dry sponge porous, the volume is basically unchanged, and it is easily dissolved in water and restored to its original state. To prevent to the greatest extent the physical, chemical and biological denaturation of dry substances.
02 Features of vegetables freeze drying machine:
1, the loss of nutrients is very small, the substance after freeze-drying is porous, and the shape is basically the same as before drying.
2, the vacuum freeze-dried substance, its physical, chemical and biological status is basically unchanged.
3, it can achieve the purpose of maintaining the original color, aroma, taste, shape and freshness of the food.
4, after adding water, it can be quickly recovered, and there is a long shelf life in a sealed container.
03 Application of fruits freeze dryer:
It is suitable for the drying of high-grade raw materials, traditional Chinese medicine, biology, wild vegetables, dehydrated vegetables, food, fruits, chemicals, drug intermediates and other materials. Freeze-vacuum drying is a new type of box structure introduced by the vacuum freeze-dryer, which combines the refrigeration system, vacuum system, thermal oil heating system and moisture drainage system. It makes great use of the material storage space in the box for freeze-vacuum drying.
