Vacuum Rake Dryer Note: Vacuum rake Dryer is a conduction-based heat transfer dryer, the heat comes mainly from the jacket with the inner wall of the heat conduction. Material does not directly contact with the heating medium, suitable for drying a small amount of heat-sensitive and oxygen-sensitive sludge, paste material, moisture content range of 15% to 90%. Dryers horizontal rake stirrer blades made of cast iron or steel, mounted on a square or circular shaft, half of the leaves to the left and the other half to the right. The rotational speed of the shaft is 7~8r/min, which is driven by the motor with decelerator. At the same time the use of automatic steering device, so that the spindle rotation every 5 ~ 8min to change a Mixer direction of rotation.
The advantages of the vacuum rake dryer in drying the material:
1. The feed granules or powder can be delivered to the container by vacuum conveying or manually.
2, with the container is constantly rotating, the material in the container for complex impact movement, to achieve uniform mixing.
3, energy saving, easy operation, low labor intensity, high work efficiency.
4, automatic temperature control, you can adjust to 20.
5, Compared with other dryer, its thermal efficiency will be doubled.
6, indirect heating, so that raw materials from pollution.
7, vacuum rake dryer features: easy washing and maintenance.
