Pneumatic vacuum feeding machine is the use of compressed air through the vacuum generator to produce high vacuum to achieve the material delivery, does not require mechanical vacuum pump, with a simple structure, small size, maintenance-free, low noise, easy to control, to eliminate material static and consistent with gmp Requirements and other advantages. Vacuum generator to produce high vacuum, so that the transport of materials to eliminate the stratification, to ensure that the homogeneity of the composition of mixed materials, is a tablet machine, capsule filling machine, dry granulator, packing machine, shaker, shaker And other machinery automatically feeding the preferred equipment.

When the compressed air supply to the vacuum generator, the vacuum generator to produce negative pressure to form a vacuum flow, the material is sucked into the suction nozzle, the formation of gas flow, through the suction tube to reach the feeding machine in the silo. The filter completely separates the material from the air. When the material is full, the controller will cut off the air supply automatically, the vacuum generator will stop working, and the hopper door will open automatically. The material will fall into the hopper of the equipment. At the same time, the compressed air automatically cleans the filter through the pulse backflush valve. Wait until the time or material level sensor to issue the feeding signal, the automatic start feeder.
