China Suppliers Factory Easy Operation Vacuum Rake Dryer with Long Service Life and Low Steam Consumption
Description
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.
Principle:
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.
Applicable materials
Mud like high paste materials with a mesh size of less than 100, various pigments, mud head like materials are filtered and centrifuged, and pure alkali detergents, alkali stone starch, dye pigments, clay ash, and other clay cement are filtered and processed.
Product features
(1) Strong adaptability and wide application
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.
(2) Good product quality
Due to the continuous forward and backward rotation of the rake teeth during the drying process, which mixes the dried material evenly to avoid overheating and easy escape of moisture, resulting in a low temperature product for the shell. Due to the fine particle size of the product, it can be packaged without the need for crushing.
(3) Low steam consumption
Due to the fact that vacuum rake dryers often use steam to pass through the jacket and use 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.
(4) Customized sealing system
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.
(5) Easy to operate
The vacuum rake dryer is easy to operate, with fewer personnel and low labor intensity. Due to the reduction of material leakage loss, environmental hygiene has been improved.
Specification
Frequently Asked Questions
What is the working principle of a vacuum rake dryer?
The material is added to the middle of the shell and moved axially by continuously rotating rake teeth. It is heated indirectly by steam through the shell inner wall. The stirring action and grinding rods break up the material, discharging vaporized moisture via a vacuum pump through dust collectors and a condenser.
What types of materials are suitable for this dryer?
It is highly suitable for mud-like high paste materials (mesh size < 100), various pigments, filtered/centrifuged mud head materials, pure alkali detergents, alkali stone starch, dye pigments, clay ash, and other clay cement.
Why does this equipment have low steam consumption?
The vacuum rake dryer utilizes latent heat by passing steam through the heating jacket. The steam consumption per kilogram of finished product is highly efficient, typically ranging between only 1.3 to 1.8 kilograms.
How does the dryer ensure good product quality?
Continuous forward and backward rotation of the rake teeth mixes materials evenly to prevent localized overheating. This allows moisture to escape easily, resulting in a low-temperature, fine-particle product that can be packaged without needing additional crushing.
What options are available for the sealing system?
Depending on the specific requirements of the materials being processed, the dryer can be configured with either a packing seal or a mechanical seal to ensure optimal sealing performance and a long service life.
