PROBLEM TO BE SOLVED: To provide a powder treatment apparatus which can avoid coagulation of powder at the time of conveyance and can achieve fluidization of the powder, even in powder having strong adhesiveness due to oil content or the like.SOLUTION: When conveying powder 2 having a desired weight or volume amount, a powder treatment apparatus introduces compressed air Q to the powder 2 while swinging the powder 2, and thereby conveys or measures the powder 2. A frequency for previously swinging the powder 2 is 0.1 Hz or more and less than 10 Hz. An amplitude when the powder 2 is swung is 5 mm or more.SELECTED DRAWING: Figure 1 |
