RTFD-GZL series vacuum freeze dryers are commercial type, used for mass production, shelf area from 1m2 to 50m2 . It uses B itzer refrigeration unit, condensation temperature -75ºC,with stable and reliable performance . CIP and SIP systems can be options.
RTFD-GZL series vacuum freeze dryers are widely used in blood products, vaccines and biological products, chemical and medicine field. In large pharmaceutical companies, freeze dryer is widely used. Freeze drying process can improve the quality of medicines and storage period.
Scope of application:
Used in pharmaceutical industry, suitable for products in bulk (in liquid, solid ,paste state, etc.) .Freezing and drying process will be finished on shelf inside drying chamber.
*Shelf is made with unique patent technology, high pressure resistance, high evenness and good temperature uniformity
*The freeze-drying curve optimization and control technology, it can control the cooling rate in the pre-freezing stage, and control the heating rate and current segment vacuum degree at the stage of sublimation drying.
*high water capture ability and high drying efficiency
*Unique double sealing technology , mobile and fixed type double sealing device for chamber door,
Sterilizing for fixed silicone rubber during steam sterilization
*In the process of drying, the vacuum degree is adjusted to avoid foaming of special substances, and the efficiency of drying is improved.
*Industrial embedded touch screen ,special modularization controller, the system is stable and reliable,and control precision is high.
*The professional design of LYO-CONTROL control system can save many process formulations.User can
adjust the process in real time, and improve process optimization rate.
*Flexible manual + automatic control mode, manual mode used to explore the process, automatic mode for batch production
*Control system with powerful functions can record and store operation data, curves and alarm records for up
to ten years, and improve the traceability of products. At the same time, it is convenient for observation,
operation and fault diagnosis.
*The user level and password can be set, the operation management can be divided and GMP related requirements can be met.
*Non - standard customization can be made according to user requirements
Options
* Eutectic point test *CIP system *SIP system *Exhaust filter for pump
* PC and control software, to control freeze dryer by PC, save and print freeze drying data
