The QVC Pneumatic Vacuum Conveyor uses compressed air to transfer powders and granules in a dust-free and efficient manner. Ideal for feeding mixers, packaging machines, and hoppers. It is widely used in food, feed, coating, pharmaceutical, chemical, ceramic, agricultural production scientific research, and other fields.

Working Principle:

1. First The vacuum transfer uses compressed air and by a vacuum, generator creates airflow (negative pressure), that pulls material through the feeding inlet.

   
   

2.  Inside the pneumatic vacuum hopper, the air and material are separated. The clean air passes through a filter and is released into the air, while the material stays and falls into a storage area (the silo).

   
   

3. When it's time to load the material, the vacuum valve closes, and the unloading valve opens. This allows the material to move into the designated receiving equipment. The system uses a blowback airbag to clean the filter automatically, so it's ready for the next cycle.

   
   

4. After unloading, the system starts again by sucking in more material.
