Shandong Weifang TCM Powder Closed Feeding Project

Headpowder successfully delivered a closed feeding system for a traditional Chinese medicine (TCM) powder production facility located in Weifang, Shandong. This project addressed critical challenges in handling fine herbal powders, ensuring dust-free operation, material integrity, and consistent feeding accuracy. The case demonstrates how headpowder helps manufacturers upgrade from open manual processes to automated, enclosed material handling.

Customer Challenges

The client reported severe dust emissions during powder transfer, leading to workplace safety concerns and material waste. Fine TCM powders tend to float, clog filters, and cause cross-contamination between batches. Manual weighing and feeding resulted in inconsistent dosage, low production efficiency, and high labor costs. Additionally, the powders are sensitive to moisture and temperature, requiring a closed environment to maintain quality. The existing open feeding system could not meet the growing demand for higher throughput and strict GMP (Good Manufacturing Practice) compliance.

Headpowder Solution

Headpowder engineered a fully enclosed pneumatic conveying and feeding system tailored for TCM powder characteristics. The solution integrates a closed hopper, negative pressure suction, planetary discharge valve, and precision weighing module—all designed to eliminate dust leakage and maintain powder flowability. The system achieves continuous, automated feeding with minimal human intervention, significantly improving dosing accuracy and operational safety. All contact parts are made of stainless steel with smooth surfaces for easy cleaning and low residue retention, supporting fast product changeovers.

Project Outcome

The installed system reduced dust emissions by over 95%, lowered material loss to near zero, and increased feeding consistency within ±0.5% tolerance. Production throughput rose by 40% while labor costs dropped, as one operator can now monitor multiple lines. The closed design also protects powders from ambient humidity and contamination, extending shelf life and ensuring batch-to-batch repeatability. Headpowder continues to provide remote monitoring and maintenance support for sustained reliable operation.
