In an apparatus configured to transport powder or granules through a plug through a transport pipe, a shut valve is attached to the transport pipe on the front side of the air knife, and an air belt valve is installed to the blowpot. The control device that opens and closes the air vent valve closes the shut valve when a power outage occurs, opens the air vent valve for a certain period of time when the power is restored, and sends pressurized gas to the air knife to remove the powder remaining in the transport pipe. 1. A high-pressure transportation device for powder and granular materials, characterized in that a power outage control means is provided for opening the above-mentioned shut valve and restarting transportation after transporting the particles. (2) In the transportation device according to claim (1), the control device for opening and closing the shuttle valve attached to the transportation pipe is provided with a control device that once closes the shuttle valve at the end of transportation and pressurizes the blowpot to a predetermined pressure. A high-pressure transport device for powder and granular material, characterized in that it is provided with residual powder processing means for discharging and pumping the powder and granular material remaining in the blowpot and the transport pipe by opening the above-mentioned shut valve again.
