ROTARY DRUM FOR USE IN A VACUUM FREEZE-DRYER

摘要

The invention relates to the general field of freeze-drying of, for example, pharmaceuticals and other high-valued goods. More specifically, the invention relates to a rotary drum (302) for use in a vacuum freeze-dryer for the bulkware production of freeze-dried particles. The drum (302) comprises a main section (304) terminated by a front plate (306) and a rear plate (308). The rear plate (308) is adapted for connection with a rotary supporting shaft for rotary support of the drum. The rear plate (308) is permeable for sublimation vapour from freeze-drying the particles.
