Abstract:
1. A pulverizing casing assembly of a food waste treatment apparatus having a pulverizing casing and a pulverizing screw provided in the pulverizing casing so as to be rotatable, the food waste treatment apparatus pulverizing, agitating and drying food waste input into the pulverizing casing, wherein the pulverizing screw rotates in the pulverizing casing in such a manner as to maintain a predetermined distance between the pulverizing screw and an inner surface of the pulverizing casing to prevent the pulverizing screw from being impeded by the inner surface of the pulverizing casing, and the pulverizing casing comprises a spherical body having a hollow space therein, wherein pulverizing ribs which are provided on a circumferential inner surface of the spherical body are spaced apart from each other, and each of the pulverizing ribs has depressions therein, wherein an imaginary line connecting the depression of the pulverizing ribs to each other forms an arc line of the circumferential inner surface of the spherical body in a direction making an angle with the pulverizing ribs.
