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.
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 no longer change until the "solid bridge" completely disappear.

Feature of Freeze Dry Machine
1. Stainless steel is polished with excellent brand to ensure surface roughness to ensure sterility requirements
2. Cabinet, board level,and hose are tested after multiple procedures to ensure without leakage
3. Shelf has high strength and can withstand long-term use;
4. Shelf through a dedicated machining, can guarantee high demand flatness;
5. Stainless steel is polished with excellent brand to ensure surface roughness to ensure sterility requirements
6. Argon welding, forming an internal and external, to ensure pipes cleanly and without leak
7. The inside wall of the condenser is cleaned by special way to ensure no dirt, ensure the system clean
8. Compressor is use Germany Bitzer , more stable performance, reliable, easy to maintain
9. According to the characteristics of freeze-dried fruit, use rotary vane vacuum pump , the pumping speed is larger and more efficient
10. Vacuum degree controlled according to set value automatic which can realize a lyophilization cycle vacuum degree of multiple variable control; Can be adjusted within 10-200pa

Application of Freeze Dry Machine
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.
