PROBLEM TO BE SOLVED: To provide a power/grain supplying method and device capable of stably supplying a fixed amount of power/grain regardless of the amount of the power/grain in a hopper. SOLUTION: This power/grain supplying device comprises a power/grain hopper 20 provided with a supplying portion 21 of the power/grain material, an air blowing out portion 30 connected to an air source 31 and installed in the hopper, a measuring portion 40 measuring the depositing amount of the power/grain material in the hopper, and a control portion 50 controlling the pressure of air blown out from the air blowing out portion in proportion to the depositing amount of the power/grain material measured by the measuring portion. The pressure of the air is controlled by gradually and continuously changing in proportion to the depositing amount of the power/grain in the hopper.
