PROBLEM TO BE SOLVED: To provide a production method of a solid detergent capable of efficiently produce a high quality solid detergent with which powdery raw materials hardly attach to a mold, when producing the solid detergent by compressing the powdery raw material using a mold.SOLUTION: A mold to be used is configured by including a mortar 3 having a through-hole 2 penetrating vertically, a lower pestle 4 slidably inserted into the through-hole 2 of the mortar 3 from under side, and an upper pestle 5 removably inserted into the through-hole from upper side. A powdery raw material 15 containing at least a soap component is filled in a cavity 6 demarcated by the mortar 3 and a pestle tip 41 of the lower pestle 4 in the through-hole 2 pressure molding the powdery raw material 15 by the pestle tip 41 of the lower pestle 4 and a pestle tip 51 of the upper pestle 5 to obtain the solid detergent 20 and discharging the solid detergent 20 from the through-hole 2. Before filling the powdery raw material 15 in the cavity 6, water is imparted on at least one surface of the pestle tip 41 of the lower pestle 4 and the pestle tip 51 of the upper pestle 5.COPYRIGHT: (C)2014,JPO&INPIT【課題】型を用いて粉体原料を圧縮して固形洗浄剤を製造する際に、型に粉体原料が付着し難く、高品質の固形洗浄剤を効率良く製造し得る固形洗浄剤の製造方法を提供すること。【解決手段】上下方向に貫通する貫通孔2を有する臼体3と、臼体3の貫通孔2に下側から摺動自在に挿入される下杵4と、臼体3の貫通孔2に上側から挿脱自在に挿入される上杵5とを含んで構成される型を用いる。臼体3と貫通孔2内の下杵4の杵先41とで画成されるキャビティ6に少なくとも石鹸成分を含有する粉体原料15を充填し、下杵4の杵先41と上杵5の杵先51とで粉体原料15を加圧成形して固形洗浄剤20を得、固形洗浄剤20を貫通孔2から排出する工程を有する。キャビティ6に粉体原料15を充填する前に、下杵4の杵先41及び上杵5の杵先51の少なくとも一方の表面に水を付与する。【選択図】図2
