What’s a Freeze Dryer/Lyophilizer
Freeze dryers and lyophilizers are designed to perform freeze drying process. And dry products under vacuum environment.
Freeze Dryer Main Components
Drying Chamber
- Freeze drying chamber is the largest part of a freeze dryer. A Pressure Container that enable create vacuum environment.
- Typically, there are several plates installed in drying chamber, to allow products placing.
Ice Condenser
- Vapors that come out from products will flow to ice condenser.
- Inside of ice condenser, a group of coils are arranged and cooled by compressor system. When the vapors hit sub-cooled coils, they will be condensed on coils surface, as ice type.
Vacuum Pump
- Create and maitain drying chamber vacuum pressure, guarantee the sublimate continuously.
Compressors
- Refrigeration system offers cooling energy to ice condenser, for vapors condensing. As well, it cools shelves, for product pre-freezing.
Heating and Fluid Circulating
- Deliver cooling energy for raw product freezing, and later deliver heating energy for sublimation and drying.
Control System
- A modern freeze drying machine use PLC based controller box, couple with a touch screen or PC software, to control and monitor the freeze dry system.
