Microwave Freeze Dryer

Microwave Freeze Dryer

Freeze-dry (brief named Freeze-dry) is a stable process of material dried which will put the material contained with water to freeze to solid first, then make among them of the water sublimate from solid to air condition, removing water to preserve materials.Products at solution stage are frozen...

According to the heating method, the dryer is divided into convection type, conduction type, radiation type and dielectric type. Convection dryers, also called direct dryers, use hot drying media to directly contact wet materials, transfer heat by convection, and take away the generated steam; conduction dryers, also called indirect dryers, use conduction The heat is transferred from the heat source to the wet material through the metal partition. The generated moisture vapor can be removed by vacuum suction, a small amount of purge gas, or condensation on the surface of a separate low-temperature condenser. This type of dryer does not use a drying medium, the thermal efficiency is high, and the product is not contaminated, but the drying capacity is limited by the heat transfer area of the metal wall, the structure is more complicated, and it is often operated under vacuum; the radiation dryer uses various radiation The device emits electromagnetic waves in a certain wavelength range, which is selectively absorbed by the surface of the wet material and converted into heat for drying; the dielectric dryer uses the action of a high-frequency electric field to cause the heat effect inside the wet material to dry.



1.Compressor is use Germany Bitzer , more stable performance, reliable, easy to maintain 2.Temperature and pressure of compressor has multiple protection features 3.Compliance with the Montreal Convention, with environmentally friendly refrigerants;

4.According to the characteristics of freeze-dried fruit, use rotary vane vacuum pump , the pumping speed is larger and more efficient

5.Electronic signatures,Three levels of user password management; 6.Automatic operation and manual operation can change in any node; 7.We can operate in the engine room and freeze-dried control room, which interlock with each other to avoid misuse; 8.A variety of components, the main components working condition and temperature, vacuum 9.Process recipe management are free to set the freeze-drying technology curve;
