PROBLEM TO BE SOLVED: To develop a blowing method for the feeding control of a powdery/granular material into targeted reaction vessel by a method adjusting the flow rate of gas. SOLUTION: The powdery/granular material is continuously fed into a chamber using a mechanical picking device, and a planar airflow is jetted and fluidized from the sidewall part in the circumference of the chamber inner bottom toward the central part of the chamber bottom. The powdery/granular material fluidized and blown into central part is sent to the entrance of a transport pipe from the chamber inside to the outside preliminarily provided in a region into which the powdery/granular material is blown. This device is provided with the picking device 9, a powdery/ granular material receiver vessel 1, a fluidized feeding chamber 14 fluidized by the air flow and sent out to the outside, and a feed pipe guiding the powdery/granular material 10 to the outside by the air flow, the picking device 9 is a mechanical type, the fluidized feeding chamber 14 has a slit nozzle jetting the horizontal planar air flow to the central part in the bottom circumferential wall, and the feed pipe has a flow inlet of the powdery/granular material positioned in the upper space in the central part of the inside bottom of the fluidized feeding chamber 14.
