Vacuum feeding is a kind of the new feeding method of using negative pressure suction material technology, cavity first form the negative pressure, material together with the air from the suction mouth into the cavity, from complete a charging process. General packaging machine, feeding machine and is used for mixing machine feeder is used. Widely used in the dairy, food, chemical medicine, veterinary drug class.

1. Is the domestic powder, granular material feeding way.
2. The material with air movement, the negative pressure feeding, wear small, high efficiency, low energy consumption.
3. The feeding pipe polyurethane hose, good equipment layout. Wear small, long service life.
4. Negative pressure conveying, good tightness, no dust, no leakage. Simple structure, modular design, easy to use
