GZLS Vacuum Freeze Dryer
The vacuum freeze drying is an advanced method for the material for the material dewatering. It freezes the moisture material in a low temperature and makes the water inside sublimate directly in the vacuum condition. Then it collects the sublimated vapor by means of the condensing way so as to dewater and dry the material.
Being processed by the vacuum freeze-drying, the physical, chemical and biological states of the material are basically unchanged. The volatile and nutritious contents in the material, which are easy to be denatured in a warm condition, will be lost a little. When the material is freezing dried, it will be formed into a porous one and its volume be basically the same to that before drying. Therefore, the processed material can be recovered quickly if being watered again, because of its large contacting area and it can be stored for a long period in a sealed vessel.
The vacuum freezing dryer can be widely used for the research and production of various heat-sensitive biological products such as vaccine, biological product, medication, vegetable vacuum packing, snake power, turtle capsule and so on.
With the development of the biological, pharmaceutical, food and health are products industries, the vacuum freezing dryer is necessary equipment in the research institutes and companies in such industries.
Features of GZLS Vacuum Freeze Dryer
Designed and manufactured based on GMP requirement, GZL vacuum freezing dryer adopts a solid construction with a small occupied area and convenient installation and transportation.
Its operation can be controlled by hand, automatic program or computer. It will be more reliable if being equipped with the antijamming unit.
The metal components as the case, plate, vapor condenser, vacuum pipeline and hydraulic device and all made of stainless steel.
Since the shelf is equipped with an advantageous stopped automatically in a bacteria-free condition so as to decrease the labor intensity and increase the product quality.
Adopting the indirect freezing and heating, the shelf is equipped with a high-efficiency heat exchanger in order reduce the temperature different between plates.
