Hubei Yichang Starch Negative Pressure Dilute Phase Project

Headpowder successfully delivered the Hubei Yichang Starch Negative Pressure Dilute Phase Project, a turnkey solution for a major starch processing facility. This case study highlights how our engineering team addressed critical material handling challenges in the starch industry.

Customer Challenge

The client operated a starch production line that relied on traditional mechanical conveying methods. Starch powder, being fine and hygroscopic, frequently caused equipment clogging and required frequent manual cleaning. The presence of suspended starch dust created a significant explosion hazard. Existing screw conveyors and bucket elevators suffered from high wear rates, leading to costly downtime and product contamination risks. The client needed a conveying system that could handle starch safely, maintain product purity, and reduce maintenance interventions.

Headpowder Solution

Headpowder implemented a negative pressure dilute phase pneumatic conveying system tailored for starch. The system uses a vacuum pump to draw starch powder from multiple feed points through sealed pipelines at low air velocity. This approach minimizes particle breakage and prevents moisture absorption. The entire conveying loop is operated under negative pressure, effectively eliminating dust escape and reducing the risk of dust explosion. An intelligent control unit monitors flow rate, pressure differential, and air-to-material ratio in real time, enabling stable and adaptive operation. The system integrates seamlessly with existing packaging and storage equipment, providing a reliable and energy-efficient upgrade.
