KFD-50 Large Capacity Industrial Food Freeze Dryer
KFD-50 Large Capacity New Design Industrial Vacuum Food Freeze Dryer
The freeze-drying method has the following advantages:
Since the water in the material exists in the form of ice crystals after pre-freezing, the dissolved inorganic salt substances originally dissolved in the water are evenly distributed in the material. During sublimation, the dissolved substances dissolved in the water are precipitated, which avoids the phenomenon of surface hardening caused by the precipitation of inorganic salts on the surface due to the migration of water inside the material to the surface in the general drying method.
The dried material is loose, porous, and sponge-like. After adding water, it dissolves quickly and completely, and restores its original properties almost immediately.
Because the drying is carried out under vacuum, there is very little oxygen, so some easily oxidized substances are protected.
Drying can remove 95%-more than 99% of the moisture, so that the dried product can be stored for a long time without deterioration.
Because the material is in a frozen state and the temperature is very low, the temperature of the heat source for heating is not high, and the normal temperature or low temperature heater can meet the requirements. If the freezer compartment and the drying compartment are separated, the drying compartment does not need to be insulated, and there will not be a lot of heat loss, so the use of heat energy is very economical.
