PROBLEM TO BE SOLVED: To provide a production method and a production apparatus of a dairy product, which hardly give an impact or vibration to a coagulum when discharging whey.SOLUTION: A production method of a dairy product includes: a temperature control process for controlling the temperature of a thing, obtained by retaining sterilized milk in a liquid-impermeable flexible sheet material 23, to be a given temperature from 30°C or more and less than 60°C a charging process for charging rennet to the milk in the sheet material 23 made to have a given temperature a cutting process for cutting a coagulum generated after the charging process a temperature maintaining process for maintaining the content of the sheet material 23 after the cutting process to be 60°C or higher for a given time and a separation process for separating the whey from the coagulum by emptying the accommodated thing of the sheet material 23 into an inner container 21 after the temperature maintaining process.COPYRIGHT: (C)2013,JPO&INPIT【課題】ホエーを排出する際、凝固物に衝撃や振動を与えにくい。【解決手段】液体を通さない柔軟なシート材23に加熱殺菌後の牛乳を溜めたものを30℃以上、60℃未満の所定の温度とする温度調整工程と、所定の温度にしたシート材23内の牛乳にレンネットを投入する投入工程と、投入工程後に生成された凝固物を切断する切断工程と、切断工程後のシート材23の内容物を所定の時間60℃以上に維持する温度維持工程と、温度維持工程後に、シート材23の収容物を内側容器21内に空けることにより、凝固物からホエーを分離する分離工程とを備えている。【選択図】図2
