Purpose:
SJIA series vaccum freeze dryer ( In situ) is suitable for laboratory samples of freeze drying test,
and a small amount of production.The machine is with shelf sheating function,using PLCtechnology
which is accurate temperature control,human-computer interface using LCD screen with curves and data.
Technical characteristics:
1.pre-freeze drying processing is in situ,put the material into the drying cabinet, it is automatic for the process of freezing and dring.
2.The machine is cascade refrigeration technology,imported compressor which is low noise,large
cooling capacity and high capacity of water capture to reduce the time of freeze drying.
3.Silicon oil is intermediate medium in the shelves for heating to Ensure drying material uniformity,
temperature discrepany is ≤1°C
4.The shelf temperature can be adjustable and control which is Easy for exploring of semi-work and production process
5.The square shelf is difficult for distortion, and easy for operation and cleaning.
6.LCD display designed as touch screen, it adopt PLC control system, can display all
important curves and data, human-computer interface can provide the user more information for relevant freeze drying process.
