PROBLEM TO BE SOLVED: To provide a method for improving hardness of fried noodle mass, and preventing crack and defect of noodle mass by arranging a noodle string group housed in a retainer at a prescribed solid position and executing an oil heat drying process.SOLUTION: As a preliminary treatment of an oil heat drying process, noodle strings are housed in a retainer so as to make a noodle mass density higher than conventional fried noodles, and pressurized gas is upward jetted from a lower part of the retainer to the noodle strings so as to make the noodle strings float.【課題】リテーナに収納された麺線群を所定の立体位置に配置し油熱乾燥処理を実施することで、フライ麺の麺塊強度を改善し、麺塊の割れや欠けを防止する方法を提供する。【解決手段】油熱乾燥工程の前処理として、従来のフライ麺よりも高麺塊密度となるように麺線をリテーナに収納し、該麺線に対してリテーナ下部より加圧気体を上部に向けて噴射し、該麺線を浮上させる。【選択図】図1
