Vacuum Dryer is a means of drying oils by vacuum evaporation pressure minus 0.8 to 1 kg/cm2 (700 mmHg), the water content of the tool is expected to fall from 0.3% to 0.1%. This device consists of vacuum tubes and 3 (three) tinggkat steam ejectors steam generator which utilizes kevacuman 12 kg/cm2 pressure of the boiler, sprinkle the oil in through the nozzle into the tube and result kevaccuman then water vapor will evaporate and exploited by the steam ejectors 1 and condensed, the remaining steam from the steam ejector sucked by an ejector 2 and terkondensasiselanjutnya last remaining steam is sucked by the ejector 3 and discharged into the atmosphere. The water formed from steam ejector 1 and 2 directly accommodated in the hot water tank under the ejector (Hot Well Tank). While the oil is more difficult to evaporate will fall gets under vacuum tube will then be pumped into storage tanks.
