Hunan Changde Powder Seamless Cleanliness Project

In the pharmaceutical industry, the cleanliness requirements faced during powder production are extremely strict. A pharmaceutical company in Changde, Hunan, has long been troubled by the difficulty of fully removing residual powder in traditional powder processing equipment. This not only reduces the risk of cross-contamination during batch changeovers but also leads to prolonged cleaning times and reduced production efficiency. To address this challenge, Head Powder has tailored a no-dead spot cleanliness project for medicinal powders, achieving a full-process cleaning upgrade through systematic optimization.
Customer pain points

In the processes of powder conveying, mixing, and packaging, the company has multiple cleaning blind spots inside the equipment. Powder tends to accumulate at pipeline elbows, valve cavities, and silo dead corners, making it unreachable by conventional manual cleaning, and chemical cleaning liquid residues may affect drug quality. In addition, frequent downtime and cleaning have led to insufficient production line utilization, and long validation cycles during batch switchovers have severely restricted capacity improvement and quality control stability.
Solutions and product advantages

To address these pain points, Head Powder offers a no-dead corner clean solution based on modular design and special surface treatment technology. The core equipment adopts a large circular arc transition structure to eliminate right angles and weld dead zones; The inner surface is finely polished to Ra≤0.4μm, and combined with the online cleaning (CIP) interface, the cleaning medium can cover all contact surfaces. At the same time, the pneumatic control system works in conjunction with automated programs to achieve a one-touch cleaning process, significantly shortening cleaning time. This solution has been validated on-site at the Changde project in Hunan, successfully shortening the cleaning cycle by 60% and lowering the risk of cross-contamination during batch switching, helping customers pass GMP compliance inspections.
