To flexibly cope with considerable variation in temporarily fitting strength and size at the time of segmenting a unit food from the tip part of the aggregate of food materials which is temporarily fitted and laminated.

Three segmenting unit 11 (a rotary tool 12 and a rotary receiving tool 15 are coaxially fixed to an axis 16) are equally divide-arranged in a form along the outer periphery of the lower tip part of the aggregate of the food materials 1A and supported in the state of being rotatable by setting each axis to be vertical by a substrate 6 and a receiving plate 8 on a lower side, and a pulley 3 is fixed to the upper tip part of each axis 16. Each unit 11 is synchronously rotate-driven through a belt roll-hooked to all the pulleys 3 in common by a motor. The lower face of the aggregate 1A is stably received by the upper face of the tool 15 of the three units 11 at an early stage and next, the unit food material 1 at a lowest order is segmented by a rotary tool 12 and this segmented food material 1 is dropped from a hollow part excepting of the fan-shaped part of the tool 15.
