Model: RTFD-50FA
General Introduction: RTFD-50FA Freeze Dryer is suitable for pilot scale or small scale production .It is suitable for drying product in bulk, with heating shelf,freezing and drying process are finished on shelf.
Freeze Drying Theory: After freeze drying process, a long term preservation for material is much easier. They can be restored to original state and maintain their chemical and biological characteristics after being watered. The vacuum freeze drying technology, which is also called sublimation drying, is a technical method that freezes the samples in advance, and then sublimates its moisture under vacuum state.
