Working principle of vacuum rake dryer
The medium is indirectly heated by wet materials such as shell, end plate, stirring shaft, transmission device, rotary joint, support part and control system (steam heats the heat transfer oil, through jacket, hollow shaft, etc.). Vacuum pump for moisture removal. If the solvent needs to be recovered, a condenser can be added. This is an innovative horizontal batch dryer, the wet material is evaporated by heat transfer, the hot surface material and the moving container are formed into a circulating flow with a scraper agitator, and the evaporated water will be pumped by a vacuum pump.
Features of vacuum rake dryer
* It has a large area of heating, which has a large area and high thermal efficiency.
* The raw materials in the cylinder form a continuous circulation cylinder, so that the uniformity of the heating of the materials is greatly improved.
* Paste or powder raw materials can be dried.
Application of vacuum rake dryer
* Pharmaceutical industry, raw material, chemical industry and other industries can be dried.
* Heat-sensitive materials require low temperature drying.
* Raw materials are easily oxidized or exploded, and are strongly irritating or toxic.
* The raw material needs to be recovered from the solvent.
In short, the equipment is better for drying paste-like materials, and customers should choose according to their own needs.
