Abstract
The new device which can be switching air flow direction is used for capsule conveying system. This device produces pulsating flows with positive and negative pressure owing to switch the suction and discharge of one blower. Behavior of the capsules moved with those pulsating flows in a pipe is experimentally examined. As a result, the effects of pulsating flows on behavior of the capsules are clear; transfer distances of the capsules depend on the difference between positive and negative pressure acting times, and the larger a mass of capsule is, the later the capsule starts to move.
