Biological material freeze-drying machine

Biological material freeze-drying machineFreeze drying of biological materials utilizes the principle of sublimationBiological material freeze-drying machineThe device freezes biological materials at low temperatures and then sublimates and dries them to remove moisture in a vacuum environment, which has the advantage of solving the stability of biological materials and preserving the original materials.Biological material freeze-drying machineIt has the technical characteristics of meeting the requirements for programmed low-temperature freezing and vacuum sublimation drying of biomaterials.

In order to facilitate the preservation and stability of biological materials, currentlyBiological material freeze-drying machineUltra low temperature freezing crystallization is carried out to form a solid, and then the ice of the solid biological material is sublimated into gas without liquefaction under programmed temperature control in a vacuum state to obtain a sponge like porous biological freeze-dried material with very little water content. The entire freeze-drying process requires treatment in a low temperature and vacuum environment. The thermosensitive and volatile substances of biological materials do not undergo enzyme growth and oxidation reactions. The thermal denaturation of materials is small at low temperatures, and the direct sublimation of water as a solid and the elimination of gases is a physical migration process. Therefore, the physical and chemical structures of biological materials are basically protected.
