Vacuum Conveying System for Powder: Sealed, Dust-Free Transfer

Vacuum powder conveying systems, as the core solution for closed, dust-free transmission technology, are deeply empowering the industrial processing of high-value powders. In the pharmaceutical and health supplement manufacturing sectors, the system achieves zero-contamination transportation of API raw materials, excipients, and vitamin powders through its fully enclosed design, meeting GMP/ISO sterile requirements. It precisely controls filling volumes to ensure the continuous operation of equipment such as mixers and tablet presses, particularly for personnel safety protection when handling high-activity raw materials (OEB 3-5 grade).

In the food and beverage industry, this technology has achieved a key breakthrough. The 316L stainless steel construction and dead-angle-free pipeline design comply with FDA/EC1935 food-grade standards, eliminating the risk of cross-contamination in the transportation of dust-prone materials such as flour, milk powder, and seasonings. Its low-friction conveying characteristics preserve crystal structure integrity—such as intact salt crystals and yeast activity retention rates of 99.2%—significantly enhancing final product quality control standards.

For the harsh environments of the chemical industry, explosion-proof certified models (ATEX/IECEx) are equipped with anti-static components and PTFE-lined pipes, enabling safe handling of hazardous materials such as carbon black and metal catalysts. Data shows that the system can reduce conveying losses of highly abrasive silica to ≤0.8%, while preventing chemical reaction failures caused by material degradation, providing equipment reliability for continuous production.

In the plastic and additive manufacturing sectors, vacuum conveying systems are redefining production processes. Using negative pressure pulse technology, masterbatch and recycled materials can be automatically transferred between injection molding machines and 3D printing equipment, with mixing homogeneity deviation controlled within ±1.5%. After deployment at a modified plastic factory, manual feeding costs were reduced by 70%, and the separation and settling issues of glass fiber fillers were completely resolved.

Applications in emerging fields continue to expand: lithium battery material transportation in new energy battery production relies on this system to achieve low-oxygen environment operation, ensuring that the moisture content of lithium iron phosphate cathode powder is ≤50ppm; mica powder, titanium dioxide, and other light-sensitive raw materials in the cosmetics industry adopt light-isolation pipeline design; agricultural premix production lines use segmented transportation solutions to precisely protect the biological activity of vitamins and enzyme preparations. With the upgrade to Industry 4.0, intelligent systems integrated with IoT sensors are becoming the core infrastructure for traceability management in pharmaceutical companies and digital twins in chemical plants.
