Overview:The vacuum harrow dryer stands out with its simplistic design, ease of operation, long service life, stable and reliable performance, minimal steam consumption, and excellent adaptability. It delivers outstanding product quality, making it ideally suited for drying paste materials sensitive to high temperatures, flammable substances, and materials prone to oxidation during temperature regulation.
Principle:
The vacuum rake dryer is an innovative horizontal batch vacuum drying system. In this apparatus, wet materials are dried through conduction. A scraper agitator continuously sweeps the material off the heated surface, ensuring uniform movement within the container and promoting efficient circulation. As the moisture evaporates, it is extracted by a vacuum pump, making the Vacuum Harrow Dryer particularly effective for drying organic intermediates and fuels in the chemical industry.
Using a steam jacket for indirect heating, the vacuum rake dryer effectively expels moisture under high vacuum conditions. This makes it perfect for drying heat-sensitive materials, substances prone to oxidation, and materials that form powders during drying (e.g., various fuels). Additionally, it is suitable for operations where the vapor or solvent must be recovered. The moisture content in the dried material can initially be as high as 90% and reduced to as low as 15%. The dried material can range from slurry, paste, granular, powdery, to fibrous forms, achieving post-drying moisture levels as low as 0.1% or even 0.05%.
The dried material is introduced from the top center of the shell. Under the continuous agitation of the rotating harrow teeth, the material's surface is constantly refreshed as it contacts the shell wall, allowing for consistent indirect heating by steam. The vaporized moisture is efficiently extracted by a vacuum pump. The system can simultaneously heat via the interlayer and harrow teeth. With high operating vacuum levels, the vapor pressure on the material's surface is significantly higher than in the evaporating space of the dryer shell, facilitating the efficient removal of moisture from both the material's interior and surface, thus achieving optimal drying results.

Features:
(1) Outstanding versatility and adaptability: Our rake-type vacuum dryer, featuring jacket heating and high-vacuum exhaust, is perfect for a wide range of materials, regardless of their properties or states. It is especially ideal for drying explosive, easily oxidized, and paste materials.
(2) Superior product quality: The continuous rotation and stirring of the rake teeth ensure uniform drying, preventing material overheating and facilitating easy moisture escape. This results in low-temperature products with fine granularity, eliminating the need for crushing before packaging.
(3) Minimal steam consumption: The vacuum rake dryer efficiently uses steam through the jacket, leveraging latent heat to warm the materials. This process ensures low steam consumption-typically between 1.3 to 1.8 kg of steam per kilogram of finished product.
(4) Customizable sealing options: Depending on the characteristics and requirements of the materials being dried, our dryer offers two sealing systems-packing seal and mechanical seal-to ensure optimal performance and safety.
(5) User-friendly operation: Our vacuum rake dryer is designed for ease of use, requiring minimal personnel and reducing labor intensity. Additionally, improved environmental sanitation is achieved due to the minimization of material loss.
Scope of application:
Our rake dryer is perfect for mud-like, high-paste materials under 100 mesh, including a variety of pigments, filter and centrifuge residues, soda detergent, alkali starch, dyes, clay ash, cement, and more.
