のである。(Effects of the invention) The present invention is such that most of the weight of the powder and granules stored in the storage tank body is received by the annular upper wall plate of the upper table, and most of the powder and granules that fall from the outer flow path are distributed inside. Since the powder and granules falling from the road are not mixed in the mixing tank and are directly discharged to the outside from the outlet, there is less resistance on the lower impeller and smooth flow is achieved, as well as a shutter for adjusting the flow rate. This has excellent practical effects such as being able to reliably supply a predetermined amount of powder to the next process by adjusting the opening degree of the opening.
