Abstract: A mix-in-the-cup automated beverage dispensing machine includes a powder dispensing system with a rotary support structure bringing each powder container to a common dispensing location in turn. The machine also provides a water heater with a thermal conduction block and a method for heating water based on pre-calculation of the required heating profile. Also provided is a fresh milk dispensing system which maintains a fully cooled flow path from the container to the cup while ensuring that all components contacting the milk are disposable single-use components. Additional features discussed relate to a mixer unit cleaned by spinning within the cup, a structurally simple cup conveyance arrangement, and an cup elevator with geometrical locking.
