Fruit freezer drying machine, is one kind of dehydrator that drying the products in vacuum condition.
Fruit freezer drying machine works by freezing the fruit at first,then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.to achive the drying purpuse.
There is no need to keep the freeze-drying products in refrigeration,can keep a lont time in normal temperature,and nearly the same with the fresh material after soaking,it’s very popular for the milddle and high cusumers.
Fruit freezer drying machine advantage:
1. Electric control unit has advanced measure system which can guarantee the quality of products
2. The material of drying box ,condenser,evaporator,vacuum tube us stainless steel according to the require of GMP
3. The refrigeration system is single stage or double stage which can reach the perfect low temperature and can be conveniently operated and repaired
4. The vacuum system is double stage vacuum which can keep products in the best vacuum condition in order to have the drying process in a shorter term
5. Lower machine assembling power and energy cost,lower price
6. Can be designed and produced according to the requirement of the customer
Advantages of Freeze Dried Products:
Freeze-drying process is carried out in a closed low temperature environment, completely separated from air dust bacteria and other pollution materials. There are almost no changes from raw materials to dried materials. The obvious advantages are:
1. Keep all ingredients of raw materials unchanged (including heat sensitive, functional, and biologically active ingredients)
2. Keep the various properties of raw materials unchanged (organization structure, appearance, color, taste, etc.)
3. Porous loose, easy to crush and disperse.
4. Easy to dissolve in water and rewater quickly.
5. Complete dehydration, easy to long-term preservation and transportation.
