An apparatus for dispensing a flowable material in a predetermined amount includes a metering wheel member ( 22 ) for delivery of the flowable material from a supply reservoir ( 12 ) to a dispensing port ( 28 ). The apparatus includes an agitator assembly ( 52 ) mounted within the supply reservoir ( 12 ) to maintain and promote flow of the material to be dispensed. A motive power source ( 30 ) is provided to effect rotation of the metering wheel member ( 22 ) and agitator assembly ( 52 ) within the supply reservoir ( 12 ). Another embodiment further provides a liquid supply system ( 84 ) for introducing liquid for rinsing or mixing. The apparatus may be further contained within a cabinet ( 68 ) for security and maintenance.
