A vacuum conveyor is material handling equipment widely used in production plants worldwide. The principle of transporting material using a vacuum conveyor differs from systems such as pneumatic or drag rod systems, where material is forced through by pressure. In a vacuum conveyor, negative pressure in the pipe attracts material towards a collection vessel.
How a Vacuum Conveyor Works
A vacuum conveyor creates a partial vacuum in an enclosed space. Air is drawn out by a pump, or another vacuum source and material is carried through the conveyor pipe by the airflow. The material is discharged into a receiver or separator where it separates from the air. The vacuum conveyor forms a closed system with little material loss through dust and minimal contamination of the surrounding environment.

Common Industrial Applications
Vacuum conveyors are used across many industries. In a food processing plant, ingredients can be moved using a sanitary vacuum conveyor between processing stages. In a pharmaceutical plant, vacuum conveyors move bulk materials such as fine powder without contamination risk. In chemical or plastics processing plants, vacuum conveying can also transport materials through pipelines.
Benefits of Vacuum Conveying
Vacuum conveyors are used for many different applications within a production line. One major advantage of the vacuum conveyors is that they can transport material within a completely sealed environment. This aids in reducing product loss, keeping the production area clean, and allows for a fully automated system.
