Dry chamber and Condenser:
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
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.
