Pneumatic Conveying System

The vacuum pneumatic conveying system utilizes compressed air to generate a high vacuum through a vacuum generator to convey materials. It eliminates the need for a mechanical vacuum pump and boasts advantages such as simple structure, small size, maintenance-free operation, low noise, convenient control, and elimination of static electricity in materials. The high vacuum generated by the vacuum generator prevents stratification of the conveyed materials, ensuring the homogeneity of the mixture's composition. It is an automatic feeding device for machines such as tablet presses, capsule filling machines, dry granulation machines, packaging machines, pulverizers, and vibrating screens.

When compressed air is supplied to the vacuum generator, it creates negative pressure, forming a vacuum airflow. Material is drawn into the suction nozzle, forming a material-air flow, which travels through the suction pipe to the feeder's hopper. A filter completely separates the material from the air. When the hopper is full, the controller automatically cuts off the air supply, the vacuum generator stops working, and the hopper door automatically opens, allowing the material to fall into the equipment's hopper. Simultaneously, compressed air automatically cleans the filter through a pulse backflush valve. The feeder automatically starts when the designated time is reached or the material level sensor sends a feeding signal.

The vacuum pneumatic conveying system uses a radio frequency generator to create a vacuum (negative pressure). This vacuum feeder draws material from the storage tank into the hopper through a suction pipe. The material then passes through a filter to separate the gas and solids. The feeding time is determined by a controller. After feeding is complete, a pneumatic door opening mechanism opens the door, allowing the material to be placed into the relevant equipment. A backflushing device blows away the powder adsorbed on the filter, removing it. The discharge door then closes, and the next cycle begins.

- It is a vacuum pneumatic conveying system which can not only automatically convey all kinds of materils to the bunker, packaging machine, injection molding machine, grinder and other equipment in the hopper, but also can directly convey the mixed material to the mixing machine.

- It is composed of many parts,such as clamping band,anti-blow bag,vacuum generator, and door sealing ring.

- It has reduced the labor intensity of workers and solved the problem of dust leakage during feeding,

which is the preferred equipment for pharmaceutical and food factories to pass GMP certification and promote clean and civilized production.

- It is made of stainless steel with polished finish that it feels glossy and smooth.It is resistant to dust, chemicals and corrosion with extended service life,which is able to keep intact as the new one.

- It adopts blocking structure, can update and maintain comfortably.It is convenient to clean and maintain,with the advantages of little niose and clean transportation.

- Compact design,delicate craftsmanship,pretty appearance,it is convenient to install and operate.And it is safe and ergonomic with excellent performace and comnfortable using experience.

- Vacuum pneumatic conveying system is suitable for the conveying of short distance and small volume.
