This case study highlights a successful implementation of a dense phase pneumatic conveying system specifically designed for coffee beans at a renowned food processing company located in Chengdu, Sichuan Province, China. The client, a medium-to-large scale food manufacturer, sought a reliable solution to transport raw coffee beans from the receiving area to the roasting and packaging lines with minimal product degradation. After evaluating multiple technologies, the company selected a dense phase conveying approach engineered and supplied by Shandong Headpowder Engineering Co., Ltd., a leading provider of bulk material handling equipment based in Shandong, China. The project not only met the stringent requirements for low breakage and gentle handling but also demonstrated the versatility of dense phase pneumatic conveying for food-grade granular materials. The entire system was customized to handle the specific flow characteristics of coffee beans, ensuring consistent throughput and maintaining the aromatic quality of the beans. This case serves as a benchmark for similar applications in the food industry, particularly for fragile and value-sensitive ingredients.
The primary products deployed in this project include a complete dense phase pneumatic conveying system optimized for coffee beans, a low breakage material handling solution, and a comprehensive food granule conveying case study that demonstrates the system's effectiveness. The dense phase conveying technology operates at low air velocity, pushing the coffee beans through the pipeline in a plug-like flow, which drastically reduces impact and friction compared to dilute phase systems. This results in a remarkably low breakage rate, typically below 0.5%, preserving the integrity of the beans and preventing generation of fines that could compromise the final product quality. The system is also equipped with a smart control module that adjusts the conveying pressure and cycle timing based on real-time feedback from sensors, ensuring consistent performance even when handling batches with varying moisture content or bean size. For the food industry, especially for delicate items like coffee beans, roasted nuts, and certain grains, the low breakage material handling feature is critical. Headpowder's engineering team performed extensive lab tests to calibrate the system parameters, achieving a transport capacity of up to 5 tons per hour over a horizontal distance of 80 meters and a vertical lift of 15 meters. The success of this case has been documented and shared as a reference for other food granule conveying applications, demonstrating how dense phase technology can replace traditional bucket elevators or screw conveyors with superior gentleness and hygiene.
Shandong Headpowder Engineering Co., Ltd., headquartered in Shandong, China, is a professional engineering company specializing in the design, manufacture, and installation of pneumatic conveying systems for a wide range of industries including food, chemical, pharmaceutical, and building materials. With over a decade of experience, the company has developed a deep understanding of the unique challenges associated with conveying fragile or cohesive materials. For the coffee bean dense phase conveying project, Headpowder provided end-to-end services from initial feasibility study and system layout design to on-site commissioning and operator training. The company's engineering team is well-versed in both dense phase and dilute phase technologies, allowing them to recommend the most cost-effective and gentle solution for each specific material. Their commitment to quality is reflected in the use of food-grade stainless steel components, sanitary seals, and easy-to-clean pipe couplings that meet the highest hygiene standards. The successful completion of the Chengdu coffee bean project has further strengthened Headpowder's reputation as a reliable partner for food processors seeking to modernize their material handling operations.

Headpowder continues to innovate and expand its product portfolio to serve the growing demand for efficient and gentle food granule conveying systems.
The dense phase pneumatic conveying system implemented for the coffee bean application offers several distinct technical advantages over alternative conveying methods. First, the low air-to-material ratio means that the beans are transported at a velocity typically between 2 and 8 meters per second, compared to 15–25 m/s in dilute phase systems. This drastic reduction in speed minimizes the kinetic energy transferred to the beans, thereby preventing cracking, chipping, or surface abrasion. Second, the system uses a pressure vessel (blow tank) to feed the material into the pipeline in a controlled, batch-wise manner, allowing for precise regulation of the conveying cycle. The blow tank design includes a fluidizing cone that ensures uniform aeration of the coffee beans, promoting smooth plug formation and reducing the risk of blockages. Third, the pipeline routing is carefully optimized to avoid sharp bends and long horizontal runs that could cause material accumulation. Headpowder's engineers employed computational fluid dynamics (CFD) simulations to model the flow behavior and identify the ideal pipe diameter, bend radius, and material composition. The resulting system achieves a conveying efficiency of over 90%, with minimal energy consumption. Additionally, the entire system is enclosed and dust-tight, preventing contamination and maintaining a clean working environment—a key requirement for food processing facilities. The low breakage material handling capability also extends the shelf life of the coffee beans by preserving their natural oils and flavors, which is a significant economic benefit for the end user.
The Chengdu food enterprise, which specializes in roasting and packaging premium coffee beans, faced several challenges with its existing material handling infrastructure. Previously, the company used a combination of manual labor and bucket elevators to move beans from storage silos to the roasting line. This method resulted in excessive bean breakage (up to 8%) and frequent downtime due to mechanical failures. The production manager contacted Shandong Headpowder Engineering Co., Ltd. after seeing a presentation on dense phase conveying at a trade show. Headpowder's team visited the site, collected samples of the coffee beans, and conducted a series of tests in their laboratory to determine the optimal conveying parameters. The final design included a 4-inch diameter stainless steel pipeline with a total length of 120 meters, incorporating three 90-degree bends and a vertical lift section. The system was equipped with a 150-liter blow tank, a compressed air supply unit with a dryer and filter, and a PLC-based control panel with a touchscreen interface. During the commissioning phase, Headpowder's engineers trained the client's operators on system operation, maintenance, and troubleshooting. The results were impressive: the breakage rate dropped to below 0.3%, the throughput increased by 25%, and the energy consumption decreased by 15% compared to the previous method. The system has been running reliably for over 18 months with zero unscheduled downtime, and the client has reported significant improvements in product quality and consistency. This food granule conveying case is now featured on Headpowder's promotional materials as a prime example of how dense phase technology can solve real-world industrial problems.
