A powder collecting and transporting device can collect powder left on a conveyer after the powder is sprinkled on cakes and bread into a laterally elongated powder container, and transport the powder in the container to a desired location by air suction. The device includes a hopper having an elongated powder discharge opening at its bottom portion and a cylindrical frame fluidly connected to the bottom portion. In the cylindrical frame, a suction pipe is rotatably provided. The suction pipe has an end portion in communication with a suction device. The suction pipe is formed with a slit at its peripheral surface. The slit forms a spiral line making one round along the longitudinal axis of the suction pipe. A part of the spiral slit is in alignment with the discharge opening to provide a suction port having small area for providing fluid communication between the hopper and the suction pipe. By rotation of the suction pipe, the suction port is moved along the longitudinal direction of the powder discharge opening.
