Pneumatic Vacuum Feeder

The pneumatic vacuum feeder utilizes compressed air to generate high vacuum through a vacuum generator for material conveying. It does not require a mechanical vacuum pump and features advantages such as simple structure, small size, maintenance-free operation, low noise, and easy control.The high vacuum generated by the vacuum generator eliminates material stratification during conveying, ensuring the uniformity of mixed material components. It is an ideal automatic feeding equipment for machines like tablet presses, capsule filling machines, dry granulators, packaging machines, crushers, and vibrating screens.

The QVC series vacuum conveying feeder is a type of vacuum feeder that uses a pneumatic vacuum pump as the vacuum source.With this vacuum feeding machine, materials can be directly fed from containers into mixers, reactors, hoppers, tablet presses, packaging machines, vibrating screens, pelletizers, hydraulic granulators, dry granulators, and crushers.The use of this feeder can reduce workers' labor intensity, eliminate powder pollution, and ensure that the production process meets GMP requirements.

For vacuum feeders with level control, automatic feeding is achieved through level control and the hopper of the receiving equipment.When the material level is higher than a certain position in the hopper of the receiving equipment, the pneumatic vacuum feeder stops feeding; however, when the material level is lower than a certain position in the hopper, the feeder starts feeding automatically. This completes the feeding process for the receiving equipment.

Main Features of Powder and Granule Pneumatic Conveyor:

When compressed air is supplied to the vacuum generator, the generator creates negative pressure to form a vacuum airflow. Materials are sucked into the suction nozzle, forming a material-air flow, and then reach the hopper of the feeder through the suction pipe.The filter separates materials from air. When the hopper is full of materials, the controller automatically cuts off the air supply, the vacuum generator stops working, and at the same time, the hopper door opens automatically, allowing materials to fall into the hopper of the connected equipment.At the same time, compressed air automatically cleans the filter through a pulse backblow valve. The pneumatic vacuum feeder starts automatically when the set time is up or the level sensor sends a feeding signal.The conveying capacity of the pneumatic vacuum feeder is closely related to the conveying distance and material characteristics.
