APPARATUS AND METHOD FOR SPRINKLING POWDER

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for sprinkling powder designed so as to uniformly sprinkle a predetermined amount of salt on Onigiri (rice-ball).

SOLUTION: The apparatus has the following structure: a salt container 1 communicates with one end of a salt flowout pipeline 2, a salt ejection nozzle 22 is provided at another end of the pipeline 2, and a vacuum generation device 3 and a vacuum break pressurization air supply pipeline 5 are connected each at the halfway portion of the pipeline 2 via ejector function. The apparatus works as follows: the vacuum generation device 3 is operated to suck salt into the pipeline 2 from the salt container 1 and eject the salt out of the nozzle 22; pressurized air is supplied to the pipeline 2 from the vacuum break pressurization air supply pipeline 5 in timing the vacuum generation device 3 stops so as to instantaneously break the vacuum in the pipeline 2 and simultaneously push the salt remaining in the pipeline 2 back to the inside of the container 1; and further, the predetermined amount of the salt is ejected out of the nozzle 22 according to the operation time every time the vacuum generation device 3 operates.
