The Sanitary Negative Pressure Delivery Project for Flour in Ningbo, Zhejiang, is implemented by Head Powder. To meet the strict requirements of the flour processing industry for cleanliness, explosion prevention, and material loss control, a complete pneumatic conveying solution has been provided. This system uses fully enclosed negative pressure conveying technology, effectively preventing dust leakage, helping the production environment meet food hygiene standards, while improving material conveying efficiency and reducing operating costs.

Customer pain points

During flour processing, traditional mechanical conveying methods face the following prominent issues: First, material exposure leads to dust pollution, which not only affects workshop hygiene but also poses a risk of dust explosions; Second, there is high loss in the conveying stage, with flour residues and clumping causing waste; Third, equipment cleaning is difficult, making it hard to meet the hygiene and production replacement needs of the food industry; Fourth, low conveying efficiency, insufficient automation, and frequent manual intervention.

Product advantages

To address these pain points, the negative pressure conveying solution provided by Head Powder has the following main features:

• Fully enclosed negative pressure conveying: The system operates under negative pressure, ensuring materials do not come into contact with the external environment throughout, preventing dust leakage, eliminating explosion hazards at the source, and keeping the workshop clean.
• Hygienic design: The pipelines and equipment inner walls are made of food-grade stainless steel, with polished surfaces with no dead corners or residues. It supports online cleaning and meets the frequent product turnover and hygiene certification requirements of the food industry.
• Low-loss conveying: The gentle negative pressure airflow reduces flour breakage and caking, keeping material loss during conveying at an extremely low level and improving raw material utilization.
• Intelligent control: Integrated automated control system can monitor conveying pressure, flow, and equipment status in real time, enabling remote operation and fault warning, reducing manual intervention and improving production continuity.

This project has been successfully put into operation at a flour mill in Ningbo, Zhejiang, operating stably. Customers have reported that workshop dust concentrations have dropped significantly, material losses have dropped by over 40%, washing and production switching times have been shortened by 60%, and overall operating costs have been significantly optimized. Head Powder will continue to support the food industry in achieving green, safe, and efficient production transformation through technological innovation.
