Vacuum feeding is a system equipment that conveys powder and granular materials through the vacuum effect of gas. It is suitable for food, beverage, medicine and many other industries, aiming at the closed conveying of various powder and granular materials, thereby improving the cleanliness of the materials. Uconn can customize a variety of conveyors that can meet different needs according to customer requirements.

The vacuum feeding system uses a water ring vacuum pump to pump air, so that the entire system is in a vacuum state. The powder and granular materials are sucked into the pipe along with the outside air to form a material flow, and pass through the suction pipe to the vacuum tank, where the air and material are separated in vacuum. . The separated materials enter the receiving equipment. Feeding and discharging are completed by continuously opening and closing the pneumatic valve. The vacuum tank is equipped with a powder switch and a pressure sensor. The opening and closing of the pneumatic valve is controlled by the PLC control center. When the powder level in the vacuum tank is higher than a certain position, the vacuum feeder stops feeding; when the material level is lower than a certain position, the vacuum feeds The machine starts automatically to complete the feeding. The vacuum feeding system is equipped with a back-blowing device. Each time the material is discharged, the compressed air pulse back-blowers the filter to knock down the powder adsorbed on the surface of the filter to ensure the normal operation of the suction material.
