PROBLEM TO BE SOLVED: To provide a powder dissolving device which can reduce laminar flow part in a dissolving tank by a simple construction in the dissolving tank and promote dissolution of powder into liquid.SOLUTION: A powder dissolving device 1 dissolves powder by stirring the powder and liquid fed into a dissolving tank 10 having a horizontal cylinder shape and comprises a rotating shaft 20 which is attached to a central part of the dissolving tank 10 and stirring blades 30 which are fixed to the rotating shaft 20. Each of the stirring blades 30 comprises support arms 31 protruding from the rotating shaft 20 in the radial direction of the dissolving tank 10 and a blade body 32 which is supported by protruding tip parts of the support arms 31 and is extended along the longitudinal inner wall of the dissolving tank 10, with an opening 33 formed by protrusion base parts of the support arms 31 and the blade body 32 being provided along the rotating shaft 20. The blade body 32 is disposed in the inner wall side of the dissolving tank 10 while maintaining a gap between itself and the inner wall of the dissolving tank 10 in such a manner that the stirring blade 30 is rotatable. Powder and liquid are lifted by rotation of the stirring blades 30 and the powder and liquid which have been lifted are made to drop into the opening 33 while they are moved in an upper side of the dissolving tank 10. |
