China Suppliers Vacuum Rake Dryer: Easy Operation, Reliable Performance, Long Service Life from Trusted Factory
It has a simple structure, convenient 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 temperature, flammable, and prone to oxidation under temperature regulation. The machine has been proven by users to be a good drying equipment through long-term use.
The dried material is added from the middle of the shell, and under the stirring of the continuously 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 grinding rod make the surface moisture of the material more effectively discharged. The vaporized moisture is discharged from the vacuum pump outlet through the dry dust collector, wet dust collector, and condenser.
Structure:
The main components of a vacuum rake dryer.
- Mud like high paste materials (mesh size
- Various pigments and dye pigments
- Filtered and centrifuged mud head like materials
- Pure alkali detergents & alkali stone starch
- Clay ash and other clay cement processing
Due to the use of jacket heating and high vacuum exhaust, the rake type vacuum dryer is suitable for almost all materials with different properties and states, especially for drying explosive, oxidizable, and paste like materials.
Continuous forward and backward rotation of the rake teeth mixes the material evenly to avoid overheating and easy escape of moisture. The resulting low-temperature product features fine particle size and can be packaged without crushing.
By utilizing steam through the jacket and latent heat to heat the material, the steam consumption per kilogram of finished product is relatively small, usually between 1.3-1.8 kilograms of steam.
According to the different characteristics and requirements of drying materials, the sealing system of the dryer can be selected from two types: packing seal and mechanical seal. The special design ensures sealing performance and service life.
The vacuum rake dryer is easy to operate, requiring fewer personnel and low labor intensity. Due to the reduction of material leakage loss, environmental hygiene is significantly improved.
It is highly suitable for mud-like high paste materials (mesh size under 100), various pigments, filter-pressed or centrifuged mud head materials, pure alkali detergents, alkali stone starch, clay ash, and other clay cement materials. It is especially ideal for heat-sensitive, flammable, and oxidizable materials.
The dryer uses continuously rotating rake teeth to move the material back and forth axially. This continuously updates the material surface in contact with the inner shell wall, ensuring even heat distribution and preventing localized overheating.
The vacuum rake dryer is highly efficient, utilizing latent heat via the steam jacket. The steam consumption per kilogram of finished dried product is relatively low, typically ranging from 1.3 to 1.8 kilograms of steam.
Depending on the specific properties of the material and processing requirements, you can choose between a packing seal or a mechanical seal. Both options are designed to guarantee excellent sealing performance and long service life.
Generally, no. Due to the fine particle size achieved through the uniform stirring of the rake teeth and the crushing action of the grinding rod, the dried product is typically ready for packaging immediately.
