Overview:The vacuum harrow dryer features a simple structure, easy operation, long lifespan, stable and reliable performance, minimal steam consumption, strong adaptability, and high product quality. It is particularly suited for drying paste materials sensitive to high temperatures, inflammable, or prone to oxidation.
Principle:
The vacuum rake dryer is an innovative horizontal intermittent vacuum drying apparatus. Wet materials undergo evaporation through conduction, with a scraper agitator ensuring continuous cleaning of the hot surface and facilitating movement within the container to promote circulation. The evaporated water is then extracted by a vacuum pump. Widely used in the chemical industry, it is ideal for drying organic semi-finished products and fuels.
The vacuum rake dryer employs a steam jacket for indirect heating and gas exhaustion under high vacuum conditions. This makes it perfect for drying materials sensitive to high temperatures, easily oxidized, or prone to powder formation (such as various fuels). It also excels in scenarios where vapor or solvents must be recovered during drying. The moisture or solvent content in the dried material can vary from 90% to as low as 15%, suitable for slurry, paste, granular, powdery, or fibrous materials. Post-drying moisture content typically reaches 0.1%, or even as low as 0.05%.
Material is fed from the top-middle part of the shell, and under continuous agitation by rotating harrow teeth, it contacts the shell wall, constantly renewing its surface. The material is indirectly heated by steam, facilitating moisture vaporization, which is then promptly extracted by the vacuum pump. The machine can heat both the interlayer and harrow teeth simultaneously. The high operating vacuum creates a significant vapor pressure difference, enhancing water discharge from the material, thus achieving the desired drying effect efficiently.

Features:
(1) Exceptional adaptability and broad application range: With its innovative rake-type vacuum drying mechanism featuring jacket heating and high vacuum exhaust, this dryer is perfectly suited for materials of varying properties and states. It is especially ideal for drying sensitive, explosive, and easy-to-oxidize paste materials.
(2) Superior product quality: The continuous positive and reverse rotation of the rake teeth ensures even stirring of the drying material, preventing overheating. This process facilitates easy moisture evaporation, resulting in a low-temperature product with fine granularity that requires no additional crushing and is ready for packaging.
(3) Minimal steam consumption: Utilizing steam to pass through the jacket and leveraging latent heat for material heating, this vacuum rake dryer exhibits significantly low steam consumption per kilogram of finished product, typically between 1.3-1.8 kg.
(4) Customizable sealing system: Depending on the specific characteristics and requirements of the drying materials, the dryer can be equipped with either a packing seal or a mechanical seal, ensuring optimal performance and flexibility.
(5) User-friendly operation: The vacuum rake dryer is designed for ease of use, requiring minimal staffing and reducing labor intensity. Enhanced environmental sanitation is achieved thanks to the reduction in material loss.
Scope of Application:
Ideal for drying mud-like and high-paste materials under 100 mesh, including various pigments, mud-like substances, filtered and centrifuged materials, soda detergent, alkali starch, dyes, pigments, clay ash, and cement.
