Overview:The vacuum harrow dryer boasts a simple structure, user-friendly operation, extended service life, stable and reliable performance, minimal steam consumption, and excellent adaptability. It is particularly ideal for drying paste materials sensitive to high temperatures, flammable, and easily oxidized under regulated temperatures.
Principle:
The vacuum rake dryer is an innovative horizontal intermittent vacuum drying system. It evaporates wet materials through conduction, with a scraper agitator continuously cleaning the hot surface material. The material circulates within the container, and the evaporated moisture is extracted by a vacuum pump. This dryer is extensively used in the chemical industry for drying organic semi-finished products and fuels.
The steam jacket in the vacuum rake dryer indirectly heats the material and expels gas under high vacuum conditions. This makes it ideal for materials that are heat-sensitive, easily oxidized, or prone to forming powder during drying (e.g., various fuels). The dryer effectively recovers vapors or solvents removed during the process. The moisture content of the dried material can vary from 90% to as low as 15%, with the final dried material reaching moisture levels as low as 0.1% or even 0.05%. Suitable for slurry, paste, granular, powdery, or fibrous materials.
Materials are introduced from the upper middle section of the shell. Under the continuous agitation of rotating harrow teeth, the materials come into contact with the shell wall, constantly renewing their surfaces. The materials are indirectly heated by steam, leading to moisture vaporization, which is promptly extracted by a vacuum pump. The system allows simultaneous heating of both the interlayer and harrow teeth. The high operational vacuum ensures the water vapor pressure on the material surface is significantly higher than in the evaporating space of the dryer shell, facilitating efficient moisture discharge and achieving optimal drying.

Features:
(1) Exceptional Adaptability and Broad Applicability: The Zpg Rake Dryer, with its jacket heating and high vacuum exhaust, is designed for a wide range of material properties and states. It is particularly suitable for drying explosive, easily oxidized, or paste materials, ensuring safe and efficient processing.
(2) Superior Product Quality: During the drying process, the harrow tooth rotates both positively and inversely, continuously stirring the material. This even distribution prevents overheating, facilitates moisture escape, and results in low-temperature products with fine granularity, ready for packaging without additional crushing.
(3) Minimal Steam Consumption: The vacuum harrow dryer utilizes steam to heat materials through the jacket, leveraging latent heat. This efficient method results in low steam consumption, typically between 1.3-1.8 kg of steam per kilogram of finished product.
(4) Customizable Sealing Systems: The dryer can be equipped with either packing seals or mechanical seals, tailored to the specific characteristics and requirements of the drying materials, ensuring optimal performance and containment.
(5) User-Friendly Operation: The vacuum harrow dryer is designed for ease of use, requiring minimal personnel and reducing labor intensity. Enhanced environmental sanitation is achieved due to the significant reduction in material loss.
Scope of Application:
Our versatile Zpg Rake Dryer is ideal for drying mud-like, high-paste materials under 100 mesh, a variety of pigments, mud head-like materials, filter and centrifuge filter residues, soda detergent, alkali starch, dyes, pigments, clay ash, cement, and more.
