Fonctionnement
Pharmaceutical freeze-drying: product is frozen on temperature-controlled shelves (≤-55°C), then water is sublimated under vacuum (ultimate ≤1.0 Pa) to condenser (≤-75°C). Refrigeration uses two BITZER two-stage compressors with R404A refrigerant. Shelf heating/cooling circuit uses 10 cst silicone oil circulated by WILO pump with PID-controlled U-shaped electric heating pipes. Hydraulic system (REXROTH) drives stoppering at 0–1.0 bar and mushroom valve (DN500) between chamber and condenser. CIP system uses USA Flowserve water ring pump and USA SSC rotating + wide-angle nozzles for in-place cleaning of chamber and shelves. PLC controls the entire automated freeze-drying cycle including defrost and CIP sequences.
