The whole device of Harrow drying machine is mainly composed of cylinder, transmission part, frame and other parts. After the dried material is added from the feeding port, the feeding port is tightly covered, steam is introduced into the jacket, and the vacuum pump is started. The main shaft of the dryer equipped with the harrow group is driven by a motor, which is decelerated by a speed reducer and then rotated forward and backward at a fixed rotation speed. The material moves to two sides along with the forward rotation of the harrow; when the harrow rotates in the opposite direction, the materials are collected from both sides to the middle. As the inside of the material is indirectly heated by steam while being evenly stirred by the harrow teeth, the moisture in the material is promoted to be gasified, and the dryer is emptied from the outlet of the vacuum pump under the action of the vacuum system.   Working principle of vacuum harrow dryer  The vacuum harrow dryer uses a steam…
