Abstract: A technique for reducing stagnation of food at a specific location on a drum when food is stirred using the drum is disclosed. The disclosed food stirring device includes: a drum that extends in an axial direction, has a hollow shape, and includes: an inlet part through which a food to be fed to an inside of the drum passes; and an outlet part that is provided at a position different from the inlet part and through which the food to be discharged from the inside of the drum passes; a drum drive device that rotates the drum around a rotation axis; a stirrer that is at least partially located inside the drum; and a support member that is attached to the drum and supports the stirrer, wherein there is a gap between an inner wall surface of the drum and the stirrer, and wherein a ratio of a shortest diameter to a longest diameter of a cross sectional surface, in a direction perpendicular to the axial direction, of a part of the stirrer that is located inside the drum is 1/3 or greater and 1 or less.
