Application:
The Dry case is designed according to vacuum vessel of international standard. Case shape is horizontal cylinder. Exterior has multitasked stiffener to strengthen. Test the vacuum air impermeability after welding. Silicone rubber is used to seal between the drying case and the case door. Sight glass with light is set on the door. Hanger rail is set on the drying case to take the products get in and out.
****Structure horizontal cylinder with stiffener Design standard vacuum vessel design
****Material: SUS or Q235A Leakage rate 25Pa×L/S (depend on Clients requirement)
Theory of freeze-drying:
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.

The advantages:
It drys at low temperature in order to make protein degeneration, micro-organisms loss biological activity.
The material in the volatile components and nutrients heated degeneration of and aromatic ingredients loss a little because of the low-temperature drying.
It is almost impossible for microorganisms and the role to grow so that the material can maintain the original character in the low-temperature drying process.
The volume and shape essentially doesn't change and has a strong water uptake after drying.
Because it has little oxygen under the vacuum drying, the vulnerable materials have been protected.
It can remove 95-99.5 percent of water, and the retention period lasts longer.
