Freeze-dried equipment is divided into three categories according to use
1. The freeze-drying machinery used in the production of medicines requires an automatic feeding system, an automatic capping system, full cleaning and sterilization in place. The system is very complicated and the price is very high.
2. Freeze-drying equipment used for food production requires large output, high production efficiency, energy saving and environmental protection. Investment costs are also relatively large.
3. Not for production, but for experimentation, or for household use. This kind of freeze-drying machine is very small, very cheap, suitable for scientific research institutions, schools and families, not suitable for business.
