The QVC-1 pneumatic vacuum feeder uses compressed air passing through a vacuum generator to create a high vacuum for material conveying, eliminating the need for a mechanical vacuum pump. It offers a simple structure, compact size, maintenance-free operation, low noise, easy control, elimination of static electricity in materials, and compliance with GMP requirements. The high vacuum generated by the vacuum generator effectively prevents segregation of the conveyed material, ensuring the uniformity of the mixed material composition. It can automatically feed tablet presses, capsule filling machines, dry granulators, packaging machines, mills, vibrating screens and other equipment.
When compressed air is supplied to the vacuum generator, it creates negative pressure and a vacuum airflow. The material is drawn into the suction nozzle, forming a material-air flow that travels through the suction pipe into the hopper of the feeder. The filter completely separates the material from the air. When the hopper is full, the controller automatically cuts off the air supply, the vacuum generator stops working, and the hopper door opens automatically so that the material drops into the equipment hopper. Meanwhile, compressed air automatically cleans the filter through the pulse back-blowing valve. When the set time is reached or the level sensor sends a feeding signal, the feeder starts automatically.
