Traditional Dewatering Clogging Issue, Self-Cleaning Vacuum Drum Filter Ensures Continuous Operation

Starch slurry contains fine particles, colloidal impurities and short fibers, which easily adhere to common filter cloth. Pore blockage occurs after long-term operation, weakening water permeability and reducing dewatering performance.

Severe clogging requires frequent shutdown for manual cleaning and cloth replacement, causing high labor and consumable costs. Intermittent operation breaks the continuous production rhythm, leads to unstable cake dryness and fluctuating product quality. It becomes a key bottleneck restricting high-efficiency operation in the final dewatering section.

The self-cleaning Vacuum Drum Filter is equipped with integrated spray washing, scraper discharging and negative pressure regeneration functions. It realizes online filter cloth cleaning without shutdown and maintains long-term stable filtration performance.

In the cyclic rotating process, high-pressure spray removes residual starch and colloidal deposits inside cloth pores, ensuring continuous water permeability. Reasonable scraper structure reduces material adhesion and prevents thick fouling. The stable vacuum system guarantees consistent solid-liquid separation and uniform dewatering effect.

This equipment supports 24-hour non-stop operation, greatly cutting manual maintenance and filter cloth replacement frequency. It perfectly meets the continuous production demands of modern starch factories and improves overall line efficiency.

1. Select Vacuum Drum Filter with built-in online self-cleaning structure for long-term stable operation.
2. Check full-coverage high-pressure spray system to eliminate dead corners of dirt accumulation.
3. Adopt anti-adhesion and corrosion-resistant filter cloth tailored for starch processing.
4. Match drum specification according to actual slurry property and production capacity.
5. Choose well-sealed vacuum structure to balance dewatering efficiency and daily maintenance.
