Bladeless Dust Collection System to Prevent Scattering in Powder Feeding Process.

Dust generated in the manufacture of pharmaceuticals and cosmetics affects worker health and safety and may contaminate the work environment. However, production efficiency is declining due to longer feeding times, and new dust control measures are necessary to ensure worker safety and improve production efficiency. In this paper, we propose a dust collection system that uses a bladeless fan to generate an air current, which promotes the adsorption of powders and particles onto the liquid surface while effectively collecting scattered dust. The effectiveness of the proposed system is demonstrated through powder feeding experiments.
