PROBLEM TO BE SOLVED: To provide a food material decomposition roller device capable of conducting adjustment of degree of decomposition of food materials by arranging a pair of decomposition rollers in proximity and rotating them in an opposite direction.SOLUTION: A pair of decomposition rollers 1a and 1b are constituted so that rotation axes are arranged in parallel and proximity each other and are decomposed and can be rotary derived in a direction that rollers are facing each other, projection rows 34 and 35 by a plurality of projections 34 and 35 arranged in a circumferential direction of a cylinder in a double-decomposition roller are arranged in a plurality of rows with a prescribed interval in an axis direction, the projection rows of the decomposition roller are arranged alternately so that a side face of a projection of one decomposition roller and a side face of a projection of another decomposition roller are facing in a cylindrical facing face of the double-decomposition roller.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】 一対の解しローラを近接配置し対向方向に回転することにより、食材の解れ具合の調整を行うことが可能な食材解しローラ装置を提供すること。【解決手段】 一対の解しローラ1a,1bを互いの回転軸を平行に近接配置し、両解しローラが互いに対向する方向に回転駆動し得るように構成し、両解しローラは円筒の周方向設けられた複数の突起34,35による突起列34’,35’が、軸方向に所定間隔を以って複数列設けられ、両解しローラの上記突起列は、両解しローラの円筒対向面において、一方の解しローラの突起の側面と他方の解しローラの突起の側面が非接触で対向するように互い違いに配置されるように構成した。【選択図】 図8
