Freeze-drying Equipment
Basic Principle of Vacuum Freeze-drying：Vacuum freeze drying process:Frozen original material first,insure the condition of vacuum and adequate heating,then the water will be removed from frozen product by sublimate,finished product will maintain frozen state and biological structure.
Features of Vacuum Freeze-dried products
1.Under the condition of low temperature vacuum drying,keep the natural activity of material
2.Natural fresh color,aroma and nutritional value retained shape and texture of fresh product is maintained,concentrated fresh flavor in finished product
3.No additives or preservatives are used-finished product is all natural
4.Low moisture,lightweight,easy to carry and keep a long shelf life.
5.Spongy structure,add water back,easy recovered in short time.
