PROBLEM TO BE SOLVED: To provide an ingredient mixing device of a cup mixing type automatic vending machine which can sufficiently mix ingredients in a short time, prevents contents from overflowing and requires less wash water for agaitating blades. SOLUTION: The agitating blades are either of a shape in which the agitating blades inscribe a sphere (diagram 1 (a)) or of a shape in which the agitating blades inscribes a rotator where the upper part is hemispherical and the lower part is cylindrical or a cylinder that slightly expands downwards (diagram 1 (b)), and the angle θ of inclination of one of agitating surfaces 55 or 55a of the agitating blades 52 or 52a slightly incline downwards with respect to a perpendicular plane. When the diameter of the rotator which the agitating blades inscribe ranges between 25 and 30 mm, the angle θ of inclination is defined as 2.5 to 15 deg.. |
