In the workshop of a traditional Chinese medicine company in Hefei, Anhui, the feeding process of micro-powdered Chinese medicine raw materials has long faced issues such as dust overflow, cross-contamination, and low labor efficiency. Head Powder has designed and implemented a dust-free feeding system for this scenario, achieving comprehensive optimization from manual feeding to automated, sealed conveying.

Customer pain points

The micropowder particles of Chinese medicine are very small (usually 80~200 mesh), making it highly susceptible to dust during feeding, which leads to excessive PM2.5 concentrations in the workshop. This not only endangers the respiratory health of operators but also leads to material waste. In addition, traditional open-end feeding methods often avoid cross-contamination between different batches, affecting drug quality stability. Manual unpacking, dumping, and weighing are labor-intensive, and production efficiency is constrained by human factors, making it impossible to match the rhythm of subsequent automated production lines.

Product advantages

Head Powder's dust-free feeding solution adopts a dual-mode design of "negative pressure sealed feeding station + pipe chain conveying system." The feeding station integrates high-precision filters and reverse blow cleaning devices, helping the feed port maintain a slight negative pressure state and dust leakage concentration below 1mg/m³; Materials are directly conveyed through sealed pipelines to the next process without manual contact throughout. The system is equipped with an intelligent weighing module and PLC control, enabling automatic weighing, quantitative feeding, and data interaction with MES systems, with feeding accuracy controlled within ±0.5%. At the same time, the equipment surface is made of food-grade 304 stainless steel, making it easy to clean without dead corners and meeting GMP certification requirements.

Implementation Results

After the project was put into operation, the workshop's dust concentration dropped below 0.3mg/m³, material loss was reduced by about 3%, and the number of operators per shift was reduced from 6 to 2, improving overall production efficiency by 40%. This plan has been operating normally for over 12 months without a single cross-contamination incident, strongly supporting the large-scale and standardized production of the customer's traditional Chinese medicine formulations.
