SWIRLING-TYPE DISSOLUTION METHOD AND SWIRLING-TYPE DISSOLUTION DEVICE

摘要

A fluid material introduction unit (3) performs a fluid material introduction step, a swirling generation unit (4) performs a swirling generation step, and a to-be-dissolved material feeding control unit (5) performs a to-be-dissolved material feeding control step to allow a to-be-dissolved material to be fed into a cylindrical container (1). A swirling fluidization step for causing the fluid material and the to-be-dissolved material to move toward a discharge part (13) on a downstream side while swirling in the cylindrical container (1), is performed, whereby, a swirling discharge step for discharging, through the discharge part (13) to the outside of a sealed container (6), a semi-dissolved material which is a resultant material of at least a part of the to-be-dissolved material having been dissolved in the fluid material, is performed.
