ABSTRACT:
A fully automatic, milk inclusive espresso coffee machine which includes coffee bean grinding and brewing apparatus and a milk aeration system which pumps a selection of milk from an internal refrigerator through a choice of aeration processes to a steaming apparatus for heating and further conditioning the milk for joining the brewed coffee liquor. With each beverage production cycle all milk is hygienically either served or returned to its refrigerated reservoir. A process is disclosed which includes pumping milk, all in a refrigerated environment, selectively along a plurality of milk lines one of which may inject air for foaming the milk to a steam delivery line for heating and steaming it and delivering it to a beverage cup. After the desired amount of milk has been delivered, the steam flow continues momentarily to cleanse the line of residual milk.
