Product Introduction

The pneumatic vacuum feeder uses compressed air to generate high vacuum through a vacuum generator to realize the transportation of materials. It does not require a mechanical vacuum pump. It has simple structure, small size, maintenance-free, low noise, convenient control, elimination of static electricity and compliance GMP requirements and other advantages. The high vacuum generated by the vacuum generator prevents the material being transported from stratification and ensures the uniformity of the composition of the mixture. It is a tablet press, a capsule filling machine, a dry granulator, a packaging machine, a crusher, and a vibrating screen. Such as mechanical automatic feeding equipment.

Working principle

When compressed air is supplied to the vacuum generator, the vacuum generator generates negative pressure to form a vacuum airflow, and the material is sucked into the suction nozzle, and the airflow of the formed material passes through the suction pipe to the silo of the feeder. The filter completely separates the material from the air. When the material is filled with the silo, the controller will automatically cut off the air source, the vacuum generator will stop working, and the silo door will open automatically, and the material will fall into the hopper of the equipment. At the same time, the compressed air automatically cleans the filter through the pulse blowback valve. When the time is up or the material level sensor sends out the feeding signal, the feeding machine is automatically started.
