Vacuum Dryer

Artech Vacuum Drying System is carried out in a closed pressure vessel with the batch at material dried stacked on trolleys. The drying process is started with an initial vacuum during which the pressure vessel and the material is evacuated completely for air. The pressure vessel is then filled with super heated steam at a temperature of 60-90 ° Celsius, and the drying is carried out by circulating the super heated steam in the pressure vessel. The drying is controlled by controlling the relative vapor pressure of the super heated steam. With a pressure lower than the atmospheric pressure, a certain vacuum will exist in the pressure vessel during the drying process, and the water will as a result of this vacuum boil out of the materials.
