Abstract: The vacuum harrow dryer drying is a commonly used mechanical equipment, as a result of vacuum harrow dryer using heated jacket, vacuum exhaust, almost all of the different nature of the materials are different from state to apply, especially for explosive, easy oxidation, paste of dry materials. Dry indoor kept rotating harrow teeth, so that material from the tube wall was kept the heat, and vacuum drying chamber, so that wet material at a lower temperature can be vaporized. And then water vapor from the interior out to dry can make material in a shorter and lower temperature to dry. The design of the raw data given on the basis of the analysis and calculation of the completion of the vacuum harrow dryer design, the choice of transmission. On this basis, in accordance with the requirements of drying capacity per hour, the volume of the drying chamber, motor, pulley, etc. Calculation of the design. Models of the simple structure, less power consumption, easy maintenance.
