Abstract: the removal of moisture from other products by freezing or sublimation. Sublimation refers to the process in which a solvent, such as water, changes directly from a solid state to a gaseous state without going through a liquid state, like dry ice. The product obtained by freeze-drying is called lyophilizer, and the process is called lyophilization. After startup, put the materials into the material box

Freeze drying is the process of removing water or other solvents from frozen biological products by sublimation. Sublimation refers to the process in which a solvent, such as water, changes directly from a solid state to a gaseous state without going through a liquid state, like dry ice. The product obtained by freeze-drying is called lyophilizer, and the process is called lyophilization. On the one hand, a part of water is taken away by vacuum system; on the other hand, when the material is frozen, the water contained in some molecules is discharged to the surface of the material for freezing. After reaching the freezing requirements, the heating system heats and dries the materials, The water contained in the material is carried to the freeze-drying box by vacuumizing to meet the freeze-drying requirements.

 Vacuum freeze dryer

The vacuum freeze-drying machine is specially manufactured by the principle of vacuum freeze-drying, with reasonable structure, convenient maintenance, low cost, automatic control and easy operation. It has the functions of freezing curve self-tuning, displaying and recording various parameters, and its working state is clear at a glance, so it is not necessary to worry about the setting of freeze-drying curve. The operator only needs to press the button to start the machine and discharge materials according to the indicator light. It has comprehensive functions, Quick freezing and freeze-drying can be completed at one time without supporting facilities (such as steam boiler, air pressure pump, etc.) and can work with power supply; it has super environmental adaptability and can operate normally at high temperature of 0 ℃; unique design, short operation cycle and extremely low energy consumption make the freezing of low price materials profitable. Freeze drying machine drying time is short, usually 8-1 hours (depending on the nature of the material). In contrast, the energy-saving effect is obvious and practical.
