Vacuum conveyor for food powders Spice vacuum conveying 

Vacuum Conveyor Working Principle   when compressed air enter into the vanuum pump, simultaneously under the push of air cylinder, the empty door of hopper will be closed and the vacuum will be formed in the hopper. The cacuum feeding machine forms air stream under vacuum state. Under the action of this air steam the material which is conveyed will be transported to vacuum hopper through hose. Certain time later (feeding time, adjustable), the compressed air is closed, the pneumatic vacuum pump is unable to produce vacuum, simultaneously under the push of air cylinder the emptying door of hopper will be opened and the cacuum will be disappeared in the vacuum feeder. The material will be fed into receiving equipment from the emptying door (for example tablet press, packing machine and so on), simultaneously, compressed air that stores up in air packet's blowbacks the filter, and the filter cleans by itself. Certain time late (discharging time, adjusta…
