In addition to the general rake vacuum dryer has all the purpose of the advantages of the rake dryer, because of the embedded hollow slurry leaves, wrong material screw belt, more than the general rake dryer has a stronger working capacity of the dry agitation, dry agitation compressive strength of the flow of water to enhance the beat, pouring material faster. Heating material can choose steam, high temperature thermal oil, boiling water. Applicable to organic solvents with high water content, must be quickly dry and agitated together with the raw materials for mixing.

　　For the solvent-containing raw materials with significant advantages, vacuum rake dryer equipment with steam cylinder clamp Jane connected to the heating of raw materials, and in a high vacuum pump under the exhaust pipe, and therefore very into the non-heat-resistant, easy to air oxidation of raw materials at high temperatures, or drying is very easy to cause powdery raw materials (such as a variety of natural materials), and its drying of raw materials in the whole process of the steam removed to ensure the acquisition of the drying of the work.

　　The imported moisture content of the raw materials to be agitated in the rake vacuum dryer is more than 95%, and the less can be more than 15%. The raw materials to be agitated are in the form of slurry, paste, granule, powder, or fiber, and the moisture content of such raw materials after agitation is usually more than 0.5%, or even 0.05%.
