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. Fully automatic operation from the pre-freeze – first drying -
second drying - end discrimination - Auto gland - Automatic
repressed - Automatic defrost - Automatic shutdown.
2. Double protection design the machine is running due to
operational errors, on the basis of protecting the product, but
also protect the safety of the machine.
3. Standard products products temperature ≤-55 ℃ cold trap
temperature ≤-75 ℃ vacuum degree ≤1Pa.
4. Modular product by system configuration, modular manufacturing,
maintenance and more professional.
5. The end discriminant function at the end of secondary drying,
the program automatically enters end discrimination in the
confirmation dried products, prompted to enter the next step.
6. Sterile isolation design reliable machine or sterile isolation
placement, user-friendly multi-site use.
7. The whole process of vacuum control provide the degree of vacuum
drying phase variable control, automated operation.
8. Shelf pitch design available shelf spacing variable function to
facilitate large difference in height lyophilized product.
9. A variety of extensions - eutectic point measurement, computer
remote control, dew point measurement functions

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.
