BFD-20S Stoppering Freeze Dryer for Pilot Production

The BFD-20S pilot freeze dryer is a stoppering tray type lyophilizer, mainly use to freeze dry pharmaceutical and biological items such as vaccines, serum and plasma, which load in vials or glass bottles. After lyophilization process finish, a hydraulic system can drive shelves move up or down for vials close.

In drying chamber, 1 module shelf contains max 5 plates can use for raw product loading, total 2.0 square meters. Rear side of drying chamber, an external type ice condenser is installed to collect vapors. Effective vapor collect capacity 30kgs/24hrs, 50kgs total.

Its control system is PLC and HMI based, same as industrial units. This system guarantees freeze dryer reliable working and precise control of the freeze drying process, as well as other desired functions which listed below.
