3Phase Vacuum 380V Freeze Drying Equipment For Vegetable
Product Description of Freeze Dry Machine
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
Vacuum freeze-drying method is a liquid → solid → gaseous process. In freeze-drying process, "liquid bridge" between the solution particles has been frozen into "solid bridge". The relative position of particles has been fixed and does not exist surface tension on gas-liquid interface between the two particles.
With the continuous distillation of solvent, "solid bridge" continuously decrease, but the the relative position between two particles will not longer change until the "solid bridge" completely disappear.
Freeze dryer is a technology that uses the principle of sublimation for drying. The dried raw materials are quickly frozen at low temperature, and then in an appropriate vacuum environment, the frozen water molecules are directly sublimated into water vapor to escape, and freeze-dried products are obtained. dry matter.

Working Principle of Freeze Dry Machine
Freeze dryer is a technology that uses the principle of sublimation for drying. The dried raw materials are quickly frozen at low temperature, and then in an appropriate vacuum environment, the frozen water molecules are directly sublimated into water vapor to escape, and freeze-dried products are obtained. dry matter.
Food freeze dryer can freeze-dry pet food, cat food, dog food, chicken breast, quail, cosmetics, liquid and other products. It is produced under low temperature and vacuum conditions. Under such production conditions, it is easy to oxidize, volatile, Heat-sensitive substances can be preserved, and the harmful effects of bacteria and enzymes can be inhibited.
