Food freeze-drying machine production line equipment

Food freeze dryer production lineVacuum freeze-drying technology is known as the most advanced drying technology since the 21st century. Food freeze-drying machines have gradually become popular due to their advantages, and the types of freeze-dried foods produced are becoming increasingly diverse.

The advantages of a food freeze dryer are: ① Maintaining the basic structure, nutritional components, and flavor substances of the food, especially the highest retention rate of physiological active ingredients. This is the main reason why some functional foods use freeze-dried food as the base material. ② The appearance does not dry or shrink, maintaining the original shape and color of the food; ③ The product has no surface hardening and a porous sponge like structure, so it has good rehydration performance, is easy to consume, and can be restored by soaking, which determines its position in ready to eat convenience foods; ④ Lightweight, resistant to storage, with no special requirements for environmental temperature. When packaged in the dark and vacuum filled with nitrogen, it can be maintained at room temperature for about 2 years. Its storage and sales costs are much lower than those of frozen food.
