PROBLEM TO BE SOLVED: To provide a strainer apparatus suitable for straining various foods heated and softened with superheated steam, while minimizing cell disruption, by passing the foods through a strainer, thereby, for example, continuously manufacturing puree retaining characteristic color, aroma, taste and nutritional value of the original food.SOLUTION: There is provided a strainer apparatus provided with a strainer member supported in a state that a conical concave surface acting as a filter surface is faced upward and a hold member supported in a state that a conical convex surface acting as a pressing surface is faced downward, and the surfaces are arranged so as to face each other interposing a gap in vertical direction. The conical center axis lines of both conical concave and convex surfaces are coaxially aligned with each other, and one of these members is rotated in one or both directions about the conical center axis line by a motive force. Raw food material softened with superheated steam is fed to the gap between the conical concave surface of the strainer member and the conical convex surface of the hold member, and the filtrate and residue are discharged to a filtered-substance collection unit and a residue collection unit, respectively.COPYRIGHT: (C)2014,JPO&INPIT【課題】過熱蒸気により加熱軟化処理された各種食材を細胞の破壊を極力抑制しつつストレーナに通過させて裏漉し処理し、食材本来の色彩、香り、味覚、栄養価がそのまま保持されたピューレを連続的に製造する場合等に好適な裏漉し装置を提供すること。【解決手段】濾過面となる円錐状凹面を上に向けた状態で支持されストレーナ部材と、押圧面となる円錐状凸面を下に向けた状態で支持されるホールド部材とが、前記円錐状凹面と前記円錐状凸面とが、互いの円錐中心軸線を同軸に整合させかつ間隙を隔てて上下に対向するように配置され、それらの部材のいずれか一方は、動力により前記円錐中心軸線の周りに1方向又は双方向へと回転し、過熱蒸気で軟化処理された原料食材は、前記ストレーナ部材の前記円錐状凹面と前記ホールド部材の前記円錐状凸面との前記間隙へと供給され、濾過物及び残渣は濾過物捕集部及び残渣捕集部にそれぞれ排出される。【選択図】図3
