A milkshake machine or similar apparatus uses the grinding and shredding principles employed by conventional impeller-type waster disposers. The milkshake machine has a housing that defines an upper grinding chamber and a lower receiving chamber separated by a rotatable impeller disk that mixes together and drives ingredients to be mixed against shredding surfaces on the inner wall of the grinding chamber. The receiving chamber has a discharge outlet, and a return inlet is provided in the housing above the grinding chamber. A discharge conduit is connected at one end to the discharge outlet at has a return port and a discharge spout at its opposite end. A return conduit is connected at one end to the return port of the discharge conduit and at its opposite end to the return inlet. A valve mechanism is provided to divert the mixed and ground ingredients expelled into the discharge conduit either into the return conduit and back into the grinding chamber or out of the discharge spout. The valve mechanism may be operated manually or by a solenoid or other suitable actuator, and a timer mechanism may be provided to toll the mixing cycle. A rinse inlet may also be provided in the housing to receive a cleaning solution on demand for cleaning the apparatus. The timer mechanism and the automatic valve mechanism may be used to control a cleaning or rinsing cycle.
