Abstract

PROBLEM TO BE SOLVED: To prevent liquid from flowing out from a cup type vessel during an agitation process and cause the liquid to quickly flow out from the vessel after the agitation process by drilling a hole through a disc type agitation vane laid near the bottom of the cup type vessel for concealing an opening. SOLUTION: In addition to a beverage flow passage formed out of a gap between an agitation vane 2 and the bottom 1b of a cup type vessel, another beverage flow passage is formed out of a plurality of through-holes 20 on the agitation vane 2. Thus, a beverage quickly flows out from the cup type vessel after an agitation process. During the agitation process, the beverage is prevented from flowing out from the cup type vessel 1, due to a centrifugal force. Also, as the through-holes 2a are formed to be radially inclined internally from the upper surface of the vane 2 to the lower side thereof, a part of the weight of the beverage tending to enter the through-holes 2a is held on the lower surrounding wall thereof. As a result, even when the speed of the vane 2 is relatively low and a centrifugal force is relatively small, or even when a centrifugal force is relatively small, due to the through-holes 2a formed at the radial internal position of the vane 2, the ingress of the beverage into the through-holes 2a is properly prevented.

BEST MODE FOR CARRYING OUT THE INVENTION A beverage stirring and mixing apparatus according to an embodiment of the present invention will be described with reference to FIG. An opening 1a is formed at the bottom of the bowl-shaped container 1. A disk-shaped stirring blade 2 is arranged in a bowl-shaped container 1. The stirring blade 2 is arranged close to the bowl-shaped container bottom wall 1b around the opening 1a and covers the opening 1a. A plurality of through holes 2a are formed in the outer edge portion of the stirring blade 2 at intervals in the circumferential direction. Through hole 2a
Are formed so as to incline radially inward from the upper surface to the lower surface of the stirring blade 2. A shaft member 3 extends vertically through the stirring blade 2. The shaft member 3 is rotatably supported by bearings 4a and 4b attached to the bowl-shaped container 1. The upper end of the shaft member is connected to the motor 6 via the coupling 5. A conduit 7 is connected to the opening 1 a of the bowl-shaped container 1.

The operation of the beverage stirring / mixing apparatus according to this embodiment having the above structure will be described. The motor 6 operates and the stirring blade 2 rotates. A liquid beverage such as coffee liquid and sugar, powdered cream or the like, or hot water and instant coffee powder, sugar, powdered cream and the like are put into the bowl-shaped container 1. The above raw materials are stirred and mixed by the rotating stirring blade 2. During stirring, the beverage attempting to enter the gap between the stirring blade 2 and the bowl-shaped container bottom wall 1b is pushed back radially outward by the centrifugal force, and the beverage attempting to enter the through hole 2a of the stirring blade 2 also The beverage in the bowl-shaped container 1 does not flow out from the bowl-shaped container 1 because the centrifugal force pushes it back outward in the radial direction. When the stirring and mixing is completed and the stirring blade 2 is stopped, the stirred and mixed beverage passes through the gap between the stirring blade 2 and the bowl-shaped container bottom wall 1b and the through hole 2a of the stirring blade 2 and is shaped like a bowl.
