the manifold fesszing and drying machine developed by yiheng co.uses the automatic changing refrigeration flow in the refrigeration system aspect,causing the cold pitfall(water vapor condenser)achieve -65℃ about,effcetively water-catch capacity,thus reducing the probability of being emulsifiled of the vacuum pump oil.the baggage shelf may heat up,speeding up the sublimation and reducing the dry cycle.the control system uses the pid control,it may voluntarily move according to the input craft when inputting the freezing and drying craft.digital demonstration temperature and vacuum degree.system disposition:the movement part se-lects the import refrigeration compressor,the disc heat interchanger,discharges the valve,the filter and so on first uses the import,has promoted the refrigeration system reliability,the stability.the contour natural,is artistic,is the scientific research institurion,the universities,colleges and institutes more ideal test equipment.
