High Difficulty in Viscous Slurry Filtration, Anti-Adhesion Vacuum Drum Filter Adapts to Viscous Materials
April 30, 2026
Tuber starch, modified starch and deep-processing by-products usually feature high viscosity and high colloid content. Such materials have strong adhesion and easily stick to filter cloth and drum surface on ordinary filtering equipment. Viscous layers block filter pores and cause material accumulation.
Material adhesion weakens vacuum water permeability, slows down dewatering speed and leads to uneven cake dryness. Factories have to reduce feeding capacity and shut down frequently for manual cleaning. It increases labor and maintenance costs, interrupts continuous production, and causes output loss and unstable batch quality, making viscous slurry filtration a long-standing industry challenge.
The anti-adhesion Vacuum Drum Filter is structurally optimized for high-colloid and high-viscosity slurry. It adopts anti-stick filter cloth, streamlined non-resistance inner cavity and precise scraper discharging system to fundamentally avoid material sticking and caking.
The polished anti-adhesion surface reduces slurry attachment. The adjustable-angle scraper and online spray cleaning system timely strip sticky materials from filter cloth and drum, preventing thick colloid accumulation. The stable vacuum system maintains even suction to form uniform filter cake and keeps consistent solid-liquid separation effect even with fluctuating slurry viscosity.
The equipment runs continuously for high-viscosity and high-colloid materials without frequent shutdown cleaning. It stabilizes production capacity and moisture content, perfectly suitable for modified starch and tuber deep-processing viscous slurry working conditions.
