The subject of the present invention is to provide a frozen dessert manufacturing device capable of preventing a mold having a plurality of bags arranged along a width direction of a brine trough from generating uneven cooling temperature and capable of increasing the cooling efficiency by uniformly spraying brine with a relatively high flow speed to the surface of the mold without increasing the flow rate of the brine. To solve the problem, the frozen dessert manufacturing device includes a brine supply pipe (30) provided with a brine nozzle (3) for supplying cooled brine to the brine accumulated in a brine trough (2), so as to freeze raw material for frozen dessert by moving a mold (4) filled with the raw material for frozen dessert along a long edge direction of the brine trough (2) inside the brine trough (2), wherein the brine nozzle formation part of the brine supply pipe (30) has a wall thickness (t) formed to be greater than the wall thickness (t0) of the other part of the brine supply pipe (30), and the flow path length of the brine nozzle (3) is configured to be greater than the wall thickness (t0) of the other part of the brine supply pipe (30), thereby giving directivity to the brine ejected from the brine nozzle (3).本發明的課題是提供一種冷凍甜點製造裝置,其不會增加濃鹽水的流量,藉由使流速較大之濃鹽水均勻地噴到模具表面,能夠防止具備沿濃鹽水槽的寬度方向排列之複數個袋部之模具的冷卻溫度產生溫度不均,並且能夠提高冷卻效率。本發明的冷凍甜點製造裝置之解決手段為:具備形成有對積存於濃鹽水槽(2)內之濃鹽水供給被冷卻後之濃鹽水的濃鹽水噴出口(3)之濃鹽水供給管(30),藉由使填充有冷凍甜點用原料之模具(4)在濃鹽水槽(2)內沿濃鹽水槽(2)的長邊方向移動來凍結冷凍甜點用原料,其中,將濃鹽水供給管(30)的濃鹽水噴出口形成部的壁厚(t)形成為大於濃鹽水供給管(30)的其他部分的壁厚(t0),並且將濃鹽水噴出口(3)的流路長度設為大於濃鹽水供給管(30)的其他部分的壁厚(t0),藉此使從濃鹽水噴出口(3)噴出之濃鹽水具有方向性。1‧‧‧冷凍甜點製造裝置2‧‧‧濃鹽水槽3‧‧‧濃鹽水噴出口3a‧‧‧濃鹽水噴出口3b‧‧‧濃鹽水噴出口3P‧‧‧板狀構件4‧‧‧模具5‧‧‧濃鹽水冷卻手段30‧‧‧濃鹽水供給管A-A‧‧‧剖面線R‧‧‧圓角t‧‧‧濃鹽水噴出口形成部的壁厚t0‧‧‧濃鹽水供給管的其他部分的壁厚t1‧‧‧板狀構件的壁厚
