Vacuum System Together with the refrigeration system, the vacuum system forms the heart of the freeze dryer Its main purpose is to evacuate the system down to the processing working pressure Its secondary purpose is to then to control at this pressure and remove the non-condensable gases during the drying process. This system can automatically control the fresh-air/recirculation selection, blower outlet selection, airflow volume selection, compressor control, and temperature control. The proposed system temperature controlled fan using microcontroller is used to control the speed of the fan according to the temperature and specify the temperature in the display. It is a control algorithm in which, in the case of HVAC applications, air or water is moved to a position proportional to the deviation of the value of the controlled variable from the set point. html Wed, 05 Jun 2019 10:54:54 EST.
