The present invention a solution that does not include the firing shell powder contains components eluted from firing shell powder, and a large amount providing a solution preparation apparatus may be prepared to. The A solution preparation apparatus 1 configuration, the main body 10 shaped container having a lid portion 15, is erected from the bottom of the body inside the body, the average particle size in the internal space S1 but the cylindrical portion 20 that houses the firing shell powder of 5 m~10 m, at least the mass per unit area on the upstream side is 500g / m 2 of the filling layer 32 of powder of powder or porous ceramics porous mineral ~800g / m 2 , a filtration layer 30 that closes the opening at the upper end of the cylindrical portion, and through the bottom opening 11 of the body The water was press-fitted into the inner space of the cylindrical portion Te and passing a hydraulically join the club to be stirred and baked shell powder and water in momentum, communicates with the outside of the space S2 of the cylindrical portion of the body, the filter layer with the press-fitting of the water was the filtrate is configured to comprise a filtrate discharge pipe 51 for discharging from the body.BACKGROUND 1【課題】焼成貝殻粉末から溶出した成分を含み焼成貝殻粉末を含まない溶液を、大量に調製することができる溶液調製装置を提供する。【解決手段】溶液調製装置1の構成を、蓋部15を有している容器状の本体10と、本体の内部において本体の底部から立設され、内部空間S1に平均粒子径が5μm~10μmの焼成貝殻粉末を収容している筒部20と、多孔質鉱物の粉末または多孔質セラミックスの粉末の充填層32の少なくとも上流側に目付が500g/m2~800g/m2の不織布フィルタの層31aが積層された層であり、筒部の上端の開口を閉塞している濾過層30と、本体の底部開口11を介して筒部の内部空間に水を圧入し、その勢いで焼成貝殻粉末と水とを撹拌させる水圧入部と、本体における筒部の外部の空間S2と連通し、水の圧入に伴い濾過層を通過した濾過液を本体から流出させる濾過液排出パイプ51とを具備する構成とする。【選択図】図1
