POWDER DISSOLVING DEVICE AND DISSOLVING METHOD

摘要

The purpose of the present invention is to provide a powder dissolving device and dissolving method that suppress the arising of undissolved powder at the bottom of a dissolution tank, thereby preventing powdered agents from remaining undissolved. This powder dissolving device 1 is provided with a dissolution tank 2 for storing a dissolving solution L, stirring blades 3 provided in the dissolution tank 2, a connecting pipe 4 linking to the dissolution tank 2 at at least two locations of different heights, and a pump P provided in the connecting pipe 4, and is characterized in that the stirring blades 3 are disposed in a position that is a prescribed spacing distance from the bottom 2b of the dissolution tank 2, and the dissolution tank 2 and the connecting pipe 4 are connected such that the dissolving solution L in the dissolution tank 2 is sent to the bottom 2b side of the dissolution tank 2 through the connecting pipe 4 by driving the pump P and the flow of the dissolving solution L discharged into the dissolution tank 2 from the connecting pipe 4 flows along the bottom 2b of the dissolution tank 2.
