Purpose:
SJIA series vacuum freeze dryer (square cabinet) is suitable for laboratory samples of freeze drying test, and a small amount of production. The machine is with shelf heating function, using PID technology 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 discrepancy is ≤1℃
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 I designed as touch screen, it adopt PID intelligent control system, can display all important curves and data, human-computer interface can provide the user more information for relevant freeze drying process.
7, Cold trap and operation panel are made by stainless steel, corrosion-resistant and easy to clean
8, The inflation valve is optional, which can be filled with inert gas.
9, The cabinet door is with high transparent colorless organic glass, the material change process can be easily observed during the operation through the transparent door.
10, The recorder and computer communication interface is optional.
