PROBLEM TO BE SOLVED: To provide a device for applying food powder which can stick power on a surface of a ball-shaped food such as a dough ball of bread thinly and evenly and can be downsized.SOLUTION: A powder applying device covers a surface of a food molded in a ball shape with powder and sends the food to a next process, and includes an inclined passage which receives a food ball having been scattered with power from an upper side and allowing the food ball to roll downward. The inclined passage includes: a first drum 70 formed into a cylinder shape allowing the food ball to roll in a hollow part and rotated in a circumferential direction and a second drum 71 arranged in series with respect to the first drum 70, rotated in a circumferential direction opposite to the first drum 70, and formed in to a cylinder shape allowing the food ball having passed through the first drum 70 to roll in a hollow part. Further, baffle member 75a, 75b are inserted in the first drum 70 and/or second drum 71, the baffle members arranged at positions blocking a rolling route of the food ball.SELECTED DRAWING: Figure 3
