Horizontal Plough Vacuum Dryer

The horizontal plough vacuum drying system integrates fully automated feeding and batching, mixing and drying, finished product packaging, and online cleaning. Leveraging advanced HMI intelligent control technology, it achieves full automation across the production process and is widely used in battery materials, food, chemicals, building materials, and other industries. The system adopts a closed-loop conveying method. Powdered raw materials are fed and conveyed dust-free through a small-bag feeding station, while liquid raw materials are pressurized from liquid storage tanks and conveyed to the dryer. Equipped with Mettler-Toledo load cells, the system achieves an accuracy of 3‰. The horizontal plough vacuum dryer integrates mixing, drying, reaction, coating, and granulation. The plough agitator, combined with high-speed choppers, materials are quickly dispersed and deagglomerated to avoid wet powder clumping. The system achieves a vacuum level of up to 5 mbar; this high vacuum significantly improves drying efficiency and results while reducing energy consumption. After drying, the material automatically enters the finished product silo and connects to the packaging system, enabling high-precision, low-dust automatic packaging. The entire system features a modular layout design and is equipped with a steel-structured operating platform, organically integrating units such as feeding, mixing and drying, discharge, finished product storage, and automatic packaging. This not only optimizes equipment layout and process integration but also facilitates operation and maintenance while improving space utilization.

Product Advantages

  • High Vacuum, High Drying Efficiency
    The machine reaches 5 mbar vacuum with excellent sealing. High vacuum greatly improves drying efficiency and effect (moisture down to 100 ppm) and reduces energy consumption. It can also serve as mixer or reactor; Positive pressure design complies with low-pressure vessel standards.
  • High-Performance Mechanical Seals
    The equipment adopts a integrated double-end mechanical seal, fully meeting the requirements of high temperature, high pressure, high speed, and high vacuum, and is equipped with a flushing monitoring system for safety and reliability. The mechanical seal position is carefully designed to effectively seal the shaft end gaps where powder accumulates, leaving no dead corners.
  • High Temperature Resistance, High Safety
    High-temperature design, max. temperature 30o°C. Unique mechanical thermal expansion compensation adapts to thermal expansion/contraction for high-temperature conditions. Explosion-proof design is available, meeting Zone 1&21 requirements for high safety.
  • Strong Corrosion Resistance, High Purity Assurance
    Excellent corrosion resistance with multiple material options. Sealing materials include: perfluoroether, PTFE, PEEK, fluorosilicone rubber, etc.; Metal materials include: Ss304/Ss31oL stainless steel, wear-resistant steel, duplex steel, Hastelloy steel, titanium, etc.; Surface coatings include: nano-ceramic coating. Teflon coating, silicon carbide coating, zirconium oxide coating, alumina coating, tungsten carbide coating, etc. This design avoids contamination of the equipment body materials, eliminates metal-to-metal contact, and ensures material purity and electrochemical performance.
  • Self-Developed Discharge Ball Valve
    SIEHE pneumatic ball valve with unique structure ensures no interference with agitator during opening/clos-ing. When closed, it fits perfectly to the inner wall for no dead zones. Equipped pulse cleaning-and-blowing.it ensures complete discharge.

Working Principle

Powder and liquid raw materials are fed into the horizontal plough dryer through raw material auto batching system. The high-speed rotating plough agitators create strong axial and radial movement, generating intense turbulence in the mixing chamber to improve mixing uniformity and efficiency. With side-mounted high-speed choppers, materials are quickly dispersed and deagglomerated to avoid wet powder clumping. The heating jacket can be heated by hot water, hot oil or steam. During drying, dust is trapped by a pulse-jet dust collector, and solvent vapor is extracted by the vacuum pump. High vacuum lowers the solvent boiling point for low-temperature drying, greatly shortening heating/cooling time and boosting drying efficiency. After drying, the material exits through the discharge port into the finished product silo, which is equipped with a de-arching device, and is then conveyed to the packaging machine through a pneumatic butterfly valve. The packaging system automatically adjusts the feed rate based on weight signals to achieve high-precision automatic packaging. At the end of a batch, the system can initiate the CIP cleaning program with a single button press. A 360°rotating spray head thoroughly rinses the mixing chamber, plough blades, and choppers, ensuring no material residue or cross-contamination.
