PROBLEM TO BE SOLVED: To provide a method which allows a raw material meat lump to be rapidly impregnated with a pickling liquid.SOLUTION: Prior to injection of a pickling liquid into a raw material meat lump B, a pretreatment step is performed with a raw material meat lump processing unit. The raw material meat lump processing unit includes a loading part 1 for the raw material meat lump B and a vertically movable gas injection head 3 opposite to the loading part 1. The gas injection head 3 includes a gas injection needle 19 to be stung into the raw material meat lump B loaded on the loading part 1. The pretreatment step includes pulling out the gas injection needle 19 after injection of gas into the meat tissue of the raw material meat lump B through the gas injection needle 19 stung into the raw material meat lump B.COPYRIGHT: (C)2014,JPO&INPIT【課題】原料肉塊にピックル液が速やかに浸透する様にする。【解決手段】原料肉塊Bにピックル液を注入する前に、原料肉塊の処理装置を用いて前処理工程を行う。この原料肉塊の処理装置は、原料肉塊Bの載置部1と、該載置部1に対向する上下動可能なガス注入ヘッド3と、を備えており、前記ガス注入ヘッド3は、前記載置部1に載置された原料肉塊Bに刺し込まれるガス注入針19を備えている。又、この前処理工程は、原料肉塊Bにガス注入針19を刺し込んで前記原料肉塊Bの肉組織の中にガスを注入した後に前記ガス注入針19を抜き出す工程を備えている。【選択図】図1
