Summary:An improvement in an apparatus for pneumatically transporting powder held in an air-tight storage container (3) to a collector (6) through a transportation tube (5), which is provided at its intermediate part with a vertically rising tube member (5b), by usinga gas pressure. The transportation tube (5) consists of a lower tube member (5a) having a tapered tubular accelerating reducer (71) and connected to the container (3), an upper horizontal tube member (5c) connected to the collector (3) and having at its starting end an inversely tapered tubular decelerating reducer (74), and the vertically rising tube member (5b) connecting these lower and upper tube members (5a, 5c) together. The tube member (5b) is provided at an intermediate part thereof with an inversely tapered tubular decelerating reducer (72), and an acceleration regulating reducer (73A) having a tapered tubular accelerating part above the bottom including a constricted part (73b), said reducers (72, 73A) being vertically connected.
