PROBLEM TO BE SOLVED: To attain a short food material, and to improve a quality in the separated and cut food material.SOLUTION: At a vegetable setting position 31, a pressing member 72 is at an elevated position. At a vegetable height inspection position 32, the pressing member abuts against a spherical vegetable or the like under its own weight. At a height calculation position 33 of the spherical vegetable or the like, a position is detected at which the pressing member abuts against the spherical vegetable or the like. An amount of the pressing member being pressed down is calculated based on the detection data so that a substantially upper portion of a central part of the spherical vegetable or the like may be longitudinally separated and cut. At a transversely separating and cutting position determining position 34, the spherical vegetable or the like is pushed down by the pressing member in accordance with the data calculated by an arithmetic processing part based on the abutting position of the pressi
