The Dye Drum Scraper Dryer is an HG series rotary dryer made for dye and pigment production. A uniform film of dye material adheres to the rotating, internally heated drum, heat conducts through the drum wall to evaporate the film moisture, and the dried product is scraped off into a screw conveyor for collection and packing. Because feed concentration, film thickness, temperature and rotation speed are all adjustable, the dryer handles different dye materials and production volumes with uniform results.
Working Principle
A rotary drum scraper dryer is a continuously rotating device with internal heating and conductivity. A layer of material adheres to the rotating drum through its lower trough. Heat is transferred through pipes to the inner wall of the drum, then to the outer wall, and finally to the material film, causing the moisture in the film to evaporate and dehydrate, thus drying the material. The dried material is then scraped off the drum by scrapers mounted on its surface and falls into a screw conveyor below the scrapers, where it is then collected and packaged.
Key Features
- Large Heating Area, High Thermal Efficiency: The generous heating area delivers high thermal efficiency and uniform heating of the material film.
- High Operational Flexibility: Feed concentration, film thickness, heating temperature and rotation speed are all adjustable to suit different materials and outputs.
- Short Drying Time: Drying takes only about 5-20 seconds, which makes the machine ideal for heat-sensitive materials.
- Simple Operation and Easy Maintenance: The dryer is simple to operate and convenient to maintain, keeping downtime low.
- Wide Applicability: The machine handles liquids and viscous materials across the chemical, dye, pharmaceutical, food and metallurgy industries.
