Dense Phase Vacuum Conveying

Vacuum Conveying has been given a “bad wrap” when handling fragile products due to the fact that many people have tried it, only to erode, or even explode, their product through a high velocity conveying line.

These experiences are, in fact, representative of conventional dilute phase vacuum conveying.

With dilute phase conveying there is a lot of air used for conveying and therefore a lot of product interaction at the high velocities necessary for conveying with traditional vacuum pumps.

Our pneumatically operated vacuum pump makes “Dense Phase” vacuum conveying possible. By being able to pull nearly a full vacuum (27” Hg.), the pump permits us to let in very little air for conveying. The product can be pulled through the line in dense slugs.

These slugs move at low velocity, with little to no product interaction. The result is the ability to vacuum convey fragile products, without damage. Obviously this opens up the door to automation, efficiency, labor savings and solving the ergonomic issues that plague the food and pharmaceutical industries.
