ZKG Series Vacuum Rake Dryer
ZKG Series Vacuum Harrow Dryer (Vacuum Harrow Impeller Dryer)
It is an innovation horizontal batch-type vacuum dryer. The moister of wet material will be evaporated by heat transmission. The stirrer with squeegee will remove material on hot surface and move in the container to form cycle flow. The evaporated moisture will be pumped by vacuum pump. Vacuum harrow dryer is mainly used for drying explosive, easy to be oxidized and paste materials. In the vacuum condition, the boiling point of solvent is decreased, and air is isolated, it avoids the material be oxidized and goes bad. Input heating medium (hot water, hot oil) into the jacket, and feed damp material into the drying chamber. Harrow teeth shaft stirs material to make the heating be uniformly. When achieve the drying requirements, open the discharging valve at the bottom of chamber, under the stirring action of harrow teeth, material moves to the middle and discharged.

Feature
·Being adapted the big area heating way,its heat conducting area is large and its
· heat efficiency is high.
· Being installed stirring in the machine, it makes raw material in cylinder form the state of continuous circle inside the cylinder,so the uniformity to be heated of raw material is raised geatly.
· Being installed stirring in the machine,pulpiness,paste-like mixture or powder raw materials can be dried easy.
· Using the newest Two-stage type reducer to reduce power consumption while increasing the torque
· Special design of discharge valve, ensure when you mixing there is no dead angles in-tank
