DELAYED FILL OF BEVERAGE MACHINE HEATER TANK

摘要

A beverage forming method and system in which a heater tank (152) can be filled with liquid to an expansion level (159) after a beverage is formed. The liquid in the heater tank may be heated, causing expansion of the liquid in the tank. Thereafter, a volume of liquid may be delivered to the tank to fill the tank to a liquid delivery level (160) at which the tank is filled to deliver a controlled volume of liquid to form a beverage. No further heating of liquid in the tank may be performed or required after filling to the delivery level since the volume of liquid delivered to fill the tank to the liquid delivery level may be relatively small. Accurate volumes of liquid may be delivered in a way that compensates for any expansion that may occur due to heating.
