Freeze Dryers (Lyophilizers)

Freeze Dryers (Lyophilizers)Product Description
Main applications:vacuum freeze drying equipment is the most advanced dehydration technology used in the food industry to produce superier quality FD food products.The FD food products have been widely used in the poducts such as FD fruits for leisure food, FD vegetables for high end convenient food, ingredients, high grade instant coffee, milk powder, convenient soap, high nutrition healthy food, herbs, military and aerospace food productsand etc.Working principle of vacuum freeze dryer:
Instead of traditional vaporization dehydrationmethod, the vacuum freeze drying technology is dehydrate products bysublimation directly from ice to vapor.During the Freeze drying process, the materials will be frozen to -18°c, then move into the vacuum drying tank for dehydration,automatic control system will set the vacuum andheatingtemperature according to the freeze drying cirve of each products to maintain the proper circumstances for FD processing.Thematerials stay in frozen status during the drying process and water vaporwill be condensed on the surface of cold trap coilsto absort the water out from the materials.Advantages of vacuum freeze dryer:
Comparing with traditionalhot air dehydrated products, the Freeze Dry products have unique characters and advantages.The most clear difference is the appearanceof the final products, the FDproducts will keep the same shape and coloras they were frozen, it won't become shrink or darken after drying.Further inside quality of the products, due to low temperature drying technology, the nutritons within the products have been preserved at the highest level. Anddue to the sublimation process had minimum damage for the material structure and cellular tissues, the rehydration rate isextremely high.After the rehydration, the productswill be withvery close charaters with the fresh materials. And many other advantages due to the low moisture content after freeze drying. The products can be stored for a very longperiod.Comparing with frozen products, it is much easierand cost efficient for transportation and storage.
