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; Shelf
through a dedicated machining, can guarantee high demand flatness;
Plate layers with constant temperature function, can realize the
automatic operation of the freeze drying process.
4. Temperature and pressure of compressor has multiple protection
features
5. Temperature protection set to avoid oil degeneration in extreme
conditions , to reduce the exhaust temperature by cooling motor
6. Liquid cooling for two times: the cooling before high-pressure
liquid enter into condenser to avoid motor heating in extreme
conditions.
7. Multi-stage vacuum setting function, you can achieve a degree of
vacuum freeze-drying cycle to control of multiple variables
8. Electric heating is controlled by PID with the characteristics
of energy efficiency and temperature stability;
9. Electronic signatures, multiple passwords;

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.
