Potato Starch Dewatering Insufficient, Vacuum Filter Supports Large-Scale Production

In the wet processing of potato starch, the dewatering section is a critical link between slurry refining and drying. Traditional dewatering equipment commonly has limitations such as low capacity, low dry substance, poor continuity and frequent maintenance, making it difficult to meet large‑scale and automated production needs.

Insufficient dewatering efficiency directly leads to slurry backlog, higher drying load, increased energy consumption and unstable product quality, becoming a core bottleneck restricting potato starch factories from expanding capacity, reducing costs and improving competitiveness. For medium and large‑scale potato starch enterprises, choosing a professional vacuum filter with high capacity, continuous stability and low energy consumption is essential for efficient large‑scale production.

The rotary drum vacuum filter is a continuous high‑efficiency dewatering device specially designed for the starch industry. Adopting proven vacuum filtration technology, it performs mechanical dewatering of potato starch slurry before drying, with outstanding strengths of large capacity, stable operation, sufficient dewatering and easy control.

Equipped with continuously adjustable drum speed, continuous level control and high‑rigidity alloy scraper, the machine can be precisely adjusted according to slurry concentration and output to ensure uniform cake, full dewatering and stable dry substance content.

The whole unit features a full stainless steel food‑grade structure with an internal cleaning system, meeting hygiene standards, corrosion‑resistant and long‑lasting. It runs with no peak current, low energy consumption and extremely low failure rate, enabling 24‑hour non‑stop operation to perfectly fit the heavy‑load and long‑cycle demands of large‑scale potato starch lines. While improving dewatering efficiency, it significantly reduces drying energy consumption and operation costs.

1. Match standard models to actual capacity: VF10 (2t/h), VF15 (4t/h), VF20 (5t/h).
2. Prioritize models with continuous operation, adjustable speed and continuous level control for efficient and stable dewatering.
3. Choose full stainless steel contact parts + internal cleaning to meet food‑grade hygiene and long‑service requirements.
4. Focus on low energy consumption, no peak current and easy maintenance to lower overall costs for large‑scale production.
5. Standard installation: after refining and before drying, to form a high‑efficiency “dewatering–drying” section.
