The vacuum rake dryer has the characteristics of simple structure, easyoperation, and long service life. Stable and reliable performance, low steamconsumption, strong applicability, good product quality, especially suitablefor drying paste like materials that are not resistant to high temperatures,flammable, and easily oxidized at high temperatures. This machine has beenproven to be a good drying equipment by users through long-term use.
Principle
The dried materialis added from the center of the shell and under the stirring of the constanty rotating rake teth, the materialmoves back and forth in thexial direction. The surface incontactwith the inner wall of the shellis constanty updated,and indirectly heated by steam. The uniform stiring ofthe rake teth andthe crushing of the crushing rod vaporize the moisture inside the material Under the action of the vacuum system, the interal and surface moisture of the driedmaterial is more effectively discharged. The vaporized moisture is discharged from the outet of the vacum pump through the dy dust collector, thermal dustcollector, and condenser.
