High Material Loss in Dewatering, Low-Residue Vacuum Drum Filter Reduces Waste

In the final dewatering stage of tuber starch processing, traditional dewatering equipment has limited filtration accuracy. Unsuitable filter cloth allows massive fine starch particles to escape with filtrate. Incomplete discharging and dead-corner accumulation also leave plenty of unrecoverable starch inside the machine.

High material loss directly reduces starch yield and raw material utilization. It also increases sewage treatment burden and environmental compliance costs. Fine starch discharged with wastewater causes resource waste and emission risks, keeping production costs high and compressing profit margins, which hinders lean production and energy saving.

The low-residue Vacuum Drum Filter adopts high-precision filter cloth, fully enclosed streamlined chamber and precision scraper discharging structure to minimize starch loss throughout filtration, adsorption and discharge.

The stable vacuum system firmly intercepts fine starch granules and prevents fine powder penetration. The streamlined inner cavity eliminates dead corners and material deposition. The adjustable precision scraper fits the drum surface closely for nearly complete cake discharge and low internal residue.

With high solid-liquid separation accuracy, the machine maintains qualified dewatering dryness while maximizing the recovery of free and fine starch. Lower solid content in filtrate reduces sewage treatment load, helping manufacturers achieve higher yield, lower waste and better environmental performance.

1. Choose low-residue Vacuum Drum Filter designed for fine starch recovery.
2. Adopt graded high-precision filter cloth to balance water permeability and particle interception.
3. Select streamlined dead-corner-free inner cavity to reduce material accumulation.
4. Equip adjustable precision scraper for thorough discharging and less residue.
5. Maintain stable vacuum system to sustain interception effect and control long-term loss.
