Vacuum freeze-drying is a kind of technology to obtain the dry products. The raw product is quick frozen under triple-point temperature state firstly﹐and make the moisture turns into the ice of the solid state, and then the ice will sublimes and directly turns vapor under the proper vacuity. The vapor will be condensed into water to drain by condenser and the product becomes dried finally.
Being processed by the vacuum freeze-drying, the physical, chemical and biological states of the material are basically unchanged. The volatile and nutritious contents in the material, which are easy to be denatured in warm condition. When the material is freezing dried, it will be formed into a porous one and its volume is basically the same to that before drying. Therefore, the processed material can be recovered quickly if being watered again. Because of its large contacting area and it can be stored for a long period in a sealed vessel.
- Products extreme dryness is 1-3% moisture content for long-term storage.
- Keep the original products structure, color & taste.
- Products easy to re-hydration.
- Products no oxygenation & deterioration. the freeze drying is the highest-technology of all dehydration methods.
The freeze drying technique difference to other ordinary drying methods is the material to be dried must be solidly frozen before and sublimate by a very high vacuum and a controlled heat input, ,i.e. ice transforms directly to vapor by passing the intermediary liquid phase.
