The vacuum rake dryer has a simple structure, easy operation, long service life, stable and reliable performance, low steam consumption, strong applicability, and good product quality. It is particularly suitable for drying paste like materials that are not resistant to high temperatures, flammable, and easily oxidized at high temperatures. The machine has been proven to be a good drying equipment by users through long-term use.
Principle: The dried material is added from the center of the shell, and under the stirring of the constantly rotating rake teeth, the material moves back and forth in the axial direction. The surface in contact with the inner wall of the shell is constantly updated, and is indirectly heated by steam. The uniform stirring of the rake teeth and the crushing of the crushing rod cause the moisture inside the material to vaporize. Under the action of the vacuum system, the internal and surface moisture of the dried material is more effectively discharged. The vaporized moisture is discharged from the outlet of the vacuum pump through the dry dust collector, wet dust collector, and condenser.
