Mini Freeze Drayer For Home/lab/factory
What Is a Freeze Dryer?
A freeze dryer removes water from a perishable material in order to preserve it, extending its shelf life and/or making it more convenient for transport. Freeze dryers work by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to change directly to a vapor (sublimate).
Vacuum pumps are required for this process, and should be sized according to the freeze-dryer. If the pump’s flow rate is too high, then vapor will be pulled through the freeze-dryer’s condenser too quickly, reducing its efficiency. It is also important to clean the condenser after each run to prevent sublimation of frozen chemicals into the vacuum pump. Chemical resistance requirements for your freeze dryer vacuum pump depend upon the aggressiveness of your solvent. Freeze-dryer applications require an ultimate vacuum of below 0.1 mbar, which can be achieved with two-stage rotary vane pumpsor.
