Professional Design Air Grain Conveyor - Dust-free negative pressure suction vacuum feeding machine – Trufiner

Working principle

Vacuum feeder is a kind of vacuum conveyor that uses electric air pump (air pump is divided into vortex fan, Roots fan, screw pump, etc.) as vacuum source. With this vacuum feeder, materials can be directly sent from the container to the mixer, reactor, hopper, tablet press, packaging machine, vibrating screen, pelletizer, wet granulator, dry granulator and pulverizer. The machine reduces the labor intensity of workers, eliminates dust pollution and ensures that the production meets the requirements of “GMP”.

The vacuum feeder is equipped with a compressed air back blowing device. During each feeding process, the compressed air pulse back blows the filter to knock down the powder sticking onto the filter surface, so as to ensure the normal operation of the suction.

For the vacuum feeder controlled for the material level, the materials in the hopper of the receiving equipment are automatically fed through the material level meter. When the hopper of the receiving equipment is higher than a certain position, the vacuum feeder stops acting and enters the standby state; When the material level is lower than a certain position, the vacuum feeder will start automatically to complete the feeding of the receiving equipment.

Product advantages

● Parameters such as suction time, discharge time and back blowing times can be set freely;

● Automatic shutdown with full material and automatic startup with insufficient material;

● Fully automatic control with PLC, original suction machine algorithm, stable, efficient and energy saving;

● The operation process is carried out in a vacuum environment to avoid cross contamination of materials with the outside world and operators;

● High conveying capacity, low energy consumption, good stability, small floor space and wide application range

● The equipment is easy to disassemble and install, with smooth inner wall, no gap and dead corner, exquisite workmanship, safe and reliable material and medical grade stainless steel 304 ; customization available for stainless steel 316, as well as the installation size.
