Commercial Industrial Food Freeze Dryer Machine Dragon Fruit Vacuum Freeze Drying Equipment
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 through sublimation and desorption, then the solvent reduce to a certain extent, thereby preventing the formation of micro-organisms or chemical reaction between the solute and solvent that products can be preserved for a long time and maintained its nature.
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.
Brief introduction
lyophilizers are consisted of food pre-freezing system, freezing and drying pot, heating system, vacuum system, refrigerating system, material conveying system and control system, etc.
The vacuum system adopts the combination of water-sealed pump and oil-sealed pump. The way of heating is closed water circulation heating. And the condenser is placed inside heating tank besides the heating plates. Of course, it can be customized according to the practical condition, for example, placed above the drying pot.
Technical Features
1 The JAPAN ULVAC vacuum pump has been stable operation ensure
2 Vacuum pump check valve of high performance and vacuum pump can
avoid backing due to the difference of atmospheric when pump stops
3 Multi-stage vacuum setting function, you can achieve a degree of
vacuum freeze-drying cycle to control of multiple variables
4 Vacuum pump connected to the chamber isolated by electric vacuum
solenoid valve he pump features an automatic isolating valve to
hold the chamber pressure in the event of power failure or vacuum
valve not reach as set point.
