Venting of pocket carryover and leakage air from rotary valves is a perennial problem. Unless this air is controlled its only escape route is up through the drop tube leading into the feeder. This causes a counter flow to the product falling into the rotary valve restricting the throughput of the system. This paper discusses the design and implementation of an in-line cyclone to obviate the disadvantages of the traditional methods employed for rotary valve venting.
