FD-500F-CE is an home and commercial food freeze dryer is referred to as food freeze dryer, food lyophilizer, commercial lyophilization machine. The items processed by vacuum freeze drying are easy to be stored for a long time. After adding water, they can be restored to the state before freeze drying and maintain the original biochemical characteristics. It is suitable for heat sensitive substances such as antibiotics, vaccines, and blood products. enzymes, hormones and other biological tissues, freeze-drying technology is very suitable and widely used in medicine, pharmaceuticals, biological research, chemical industry, food and other fields.
