_{We solemnly promise our users:}

Freeze dryer is a new type of drying equipment, which uses refrigeration technology to freeze materials into solid state and dry them under low temperature and pressure. Its advantages include simple operation, easy maintenance, and better rehydration of the dried products. At present, vacuum freeze dryer is suitable for drying various materials such as food. In the freeze-drying process, there exists a certain ratio of surface area to material thickness after dispensing into a container, and both the bulk density of the material and the component density of the liquid have an effect on the freezing time of the material. The advantages of freeze drying are: 1. Freeze drying is carried out at low temperatures , so it is particularly suitable for many heat-sensitive substances. For example, proteins, microorganisms and the like do not undergo denaturation or lose their biological viability. Therefore, it is widely used in the food field. 2. The weight of freeze-dried food is light , meat and eggs can be reduced by 50-60%, vegetables and fruits by 70-90%. 3. Freeze-dried food can be preserved for a long time without deterioration. Generally, refrigeration and air-conditioning preservation can be preserved for a few months, up to 1 year, while freeze-dried food can be preserved for as long as 5 years.
