## Abstract

A decant device includes a tubular body being hollowed and having an upper end and a lower end being open. The lower end is capable of combining with a mouth of a cup. A dispenser is assembled in the tubular body. The dispenser has a plate body laterally connected to an inner wall of the tubular body. The plate body has a center portion and the plate body has a curved surface downwardly protruding from a bottom of the plate body and a recessed surface concaved from a top of the plate body. The plate body has a plurality of fan-shaped through holes surrounding the center portion, so as to form the plate body as turbine-shaped.
