WSG series of rotary vacuum dryerThermal energy (such as hot water,Website:http://www.zhongyuanfenti.com, low pressure steam or heat conduction oil) goes through an airtight layer, heat passes to the drying material through the inner wall. Under power driven, the tank shall slowly rotate, tank material will unceasingly mix, thus achieving the goal of strengthening drying effect. Materials are in the vacuum state, the vapor pressure drop will make material surface moisture (solvent) reach saturation condition and evaporate, and exhaust recycling could be realized by the vacuum pump in a timely manner. Materials inner moisture (solvent) will infiltrate and discharge continuously to the surface, the material shall achieve drying in a short time. Working dataNameGross volume10035050075010001500200030004500Gross volumeL10035050075010001500200030004500working volumeL50175250375500750100015002250heated aream²1.1622.633.54.615.587.59.623.8rotate speedrpm666666644powerkw1.12.245.57.57.5111522rotation heightmm160019302060216022602760316035004150in-tank design pressureMpa-0.09～-0.096interlayer design pressureMpa0.3
