This case study presents a successful implementation of a sugar powder dilute phase pneumatic conveying system designed and installed by Shandong Headpowder Engineering Co., Ltd. (referred to as headpowder) for a well-established food processing company located in Zhenjiang, Jiangsu Province. The client required a reliable, hygienic, and efficient solution for transferring fine sugar powder from the grinding workshop to the packaging line, while maintaining product integrity and minimizing dust emissions. The project involved a complete turnkey supply of the dilute phase pneumatic conveying system, including the feeder, pipeline network, cyclone separator, bag filter, and control system. The system operates at a conveying capacity of 3 tons per hour over a horizontal distance of 50 meters and a vertical lift of 10 meters, successfully meeting the client's production requirements.
The sugar powder dilute phase conveying case highlights the competence of headpowder in handling fine, cohesive, and hygroscopic food powders. In this project, the sugar powder (average particle size 100–150 microns) is conveyed using a positive pressure dilute phase system, where the material is suspended in a high-velocity air stream and transported through a closed pipeline. The system is designed to prevent sugar powder caking, moisture absorption, and contamination. Key components include a rotary airlock feeder, a Roots blower, a stainless steel conveying line with smooth interior surfaces, and a reverse-jet filter receiver. The dilute phase pneumatic conveying system ensures gentle handling of the sugar powder, preserving its physical properties while achieving continuous, dust-free operation.
Food powder conveying is a critical process in the confectionery, bakery, and beverage industries. The Zhenjiang facility produces various sugar-based products, and the existing manual handling method caused significant dust hazards, product loss, and labor inefficiency. By adopting headpowder's dilute phase pneumatic conveying system, the client achieved a completely enclosed and automated material transfer process. The system is equipped with a PLC-based control unit that monitors pressure, airflow, and material flow rate in real time, allowing precise batch feeding and reducing waste. The food powder conveying system also complies with GMP (Good Manufacturing Practice) standards, featuring easy-clean design with quick-release couplings and CIP (Clean-in-Place) capability. This significantly reduces downtime for cleaning and maintenance.
The dilute phase pneumatic conveying system supplied by headpowder offers several distinct advantages for this sugar powder application. First, the high air-to-material ratio ensures low product degradation, which is essential for fragile sugar crystals. Second, the system operates at relatively low positive pressure (0.5–1.0 bar), reducing energy consumption compared to dense phase systems. Third, the pipeline layout is flexible and can be easily adapted to the existing plant structure, minimizing civil works. Fourth, the integrated dust collection system (bag filter with pulse-jet cleaning) captures any fine particles, ensuring a clean working environment and meeting local environmental regulations. The dilute phase conveying system also allows for multiple discharge points, enabling the client to feed several packaging machines simultaneously from a single conveying line.
The project was executed in three phases: design, fabrication, and installation/commissioning. After a detailed site survey, headpowder's engineering team customized the system to accommodate the existing building height constraints and the need for future expansion. The entire system was fabricated from 304 stainless steel, with all contact surfaces polished to a Ra ≤ 0.8 μm finish to prevent bacterial growth and facilitate cleaning. Installation was completed within 15 working days, and the commissioning involved a 72-hour continuous trial run under full load. The final results showed a conveying efficiency of 98.5%, with no detectable sugar powder leakage. The client reported a 40% reduction in labor costs, a 30% decrease in product loss, and a significant improvement in workplace air quality. The system has been in stable operation for over 18 months without any major downtime.
