Vacuum conveying is a method used to transport bulk materials through a system of pipes using suction. This process involves creating a vacuum that pulls the materials from one location to another, making it efficient for moving powders, granules, and other small particles. It is commonly used in industries such as food processing, pharmaceuticals, and plastics. The system typically consists of a vacuum pump, a conveying line, and a receiver. The vacuum pump generates the suction needed to move the materials, while the conveying line directs them to the desired location. This method minimizes dust and spillage, ensuring a cleaner and safer working environment.
