Ingredient mixing bowl and evacuation system

摘要

A mixing device and overflow evacuation system for a vending machine which is capable of mixing a predetermined portion of dry ingredients with a liquid and vending the resultant mixture. The mixing bowl is generally conically shaped and open at its upper end with an annular cap covering the upper end with a central opening which permits the dry ingredient to be dispensed into the mixing bowl therethrough. The liquid is injected so as to cause the liquid to move in a generally spiral path around the mixing bowl and the dry ingredient is injected into the path of the liquid so that the two are mixed. The mixing bowl is provided with baffles in the lower portion thereof which break up the flow and cause the mixture to pass through an outlet spout. The evacuation system includes a vacuum tube connected to the upper portions of each of the mixing bowls to remove steam therefrom when hot liquids are being used. In the case of a clogged mixing bowl, the overflow system will remove the liquid and transport it to a catch basin to prevent an overflow of the liquid in the machine.
