Freeze drying machine for biological productscorrectA device used for vacuum freeze-drying of biological product materials, capable of removing active substances and molecular structures while maintaining their original state99%The above moisture has good rehydration properties and can be stored for a long time at room temperature.SFDThe freeze-drying machine for biological products has been widely used by biological enterprisesWorking principle and function，Used for freeze-drying processing of various biological products.

The working principle of a biological product freeze-drying machine is to utilize the three state changes of water: liquid, solid, and gas, which can be converted or coexist with each other at different temperatures and vacuum states. By utilizing the principle of sublimation, water containing biological products are pre frozen and crystallized into a solid state at low temperatures. Then, in a vacuum environment, the solid water molecules are directly sublimated into gas for removal, resulting in water containing products1%Biological freeze-dried products within. During the drying process of the bio freeze dryer, it operates in an ultra-low temperature and vacuum environmentNot becausesublimationDehydration leads to concentrationcollapsePhenomenon,At the same time, avoid under vacuum and oxygen free conditionsoxidation. drybiologicsIt is in the form of a dry sponge with multiple pores, and its volume remains basically unchanged,Has instant solubility inRestore the original state with water.The biological freeze-drying machine effectively performs in the vacuum freeze-drying processPrevent dryingbiologicsofChanges in physical structureAnd Biologyactivedenaturation.

The biological product freeze dryer has functions such as refrigeration, vacuum, heating, circulation, and control. The entire operation of the freeze dryer equipment is controlled by a PLC electronic control system, and it has the ability to set and modify the freeze drying process, record, store, and trace operating data. It has functions such as heating rate control, vacuum fine adjustment control, front and rear box partition valve control, including eutectic point online testing, endpoint judgment, slope temperature control, remote operation and monitoring, password permission management, etc. The SFD biological product freeze-drying machine equipment meets the requirements of cGMP standards and is widely used in various biological detection reagent freeze-drying, biological gene cell freeze-drying, microbial freeze-drying, biological protein freeze-drying, and biological fermentation freeze-drying processes.
