Vacuum - How a Vacuum Conveyor Works

Vacuum is generated either by using compressed air through COAX® technology or a (1) mechanical pump (not shown on this photo). Vacuum is crucial for ensuring efficient and safe transport of powders and granules in  accordance with operational requirements.

When the vacuum process is initiated, the bottom valve (2) is closed to allow an increasement of vacuum in the container (3) and in the conveying line (4). This vacuum creates a suction force, enabling the product to transferred from the feeding point (5) into the transport line and onwards to the desired destination, such as a container or another receptacle.

To ensure reliable operation and protect the equipment from damage and contamination, a filter (6) is utilized. This filter prevents dust and small particles from entering the pump and the surrounding environment, thereby maintaining clean and efficient operation as well as ensuring a good working environment.

During the transport process, an air shock tank is filled with compressed air (7). When it is time to stop the transport, the pump is switched off at a preset or automatic time interval. Hereafter, the bottom valve is opened to release the stored material. Simultaneously, an air pulse is activated to clean the filter from any accumulated dust or small particles.

Once the cycle is completed and the pump is restarted, the process begins again, initiating a new cycle of vacuum transport. The specific duration for suction and emptying time is typically controlled by a pneumatic or electric control system or completely automated using intelligent PLC systems.

Vacuum technology is an effective way to transport and handle powders and granules in industrial environments. Vacuum transport also contributes to improved productivity with minimized product loss.
