Drum Coating

Drum Coating covers SINOTHERMO's HG/GT vacuum drum scraper dryer, which applies and dries a thin material layer on a rotating drum surface under vacuum. A scraper blade continuously removes the processed product, giving consistent throughput for coating pastes, slurries and laminated materials.

HG/GT-Vacuum Drum Scraper Dryer

Categories: Conduction and Vacuum Dryer

Continuous Drying for Paste-like Materials:

In operation, the rotating drum picks up material as a thin film. Heat transfers from the inner to the outer wall, effectively evaporating moisture, while an internal scraper continuously converts the dried film into flake-like product in a short time.

Input:: Pasty, Viscous and Thick Materials
Output:: Flake-like Solids with 5%–8% moisture content
Temperature:: Inlet air temperature range of 120°C to 260°C
Additional Feature:: Cooling

Continuous Coating and Drying in a Rotating Drum

The HG/GT vacuum drum scraper dryer combines rotating-drum contact drying with continuous scraped discharge — applying and drying a thin material layer on the drum surface under vacuum before a scraper blade continuously removes the processed product.

Drum Coating Process Advantages

Continuous operation suits high-volume processing of pastes, slurries and viscous coating materials. Vacuum operation lowers drying temperature, protecting heat-sensitive coated or laminated materials. The scraper mechanism prevents material buildup on the drum, keeping throughput consistent over long production runs.
