Abstract
A dispenser for dispensing and a method of dispensing an ingredient for a machine. An ingredient feed mechanism dispenses the ingredient to the machine. A controller is capable of controlling an amount of the ingredient delivered to the machine by varying an amount of time the ingredient feed mechanism is active. The controller has a demand mode which varies the amount of time the ingredient feed mechanism is active as a function of a parameter obtained from the machine. The controller compares the amount of time the ingredient feed mechanism is active with a reference value and switches to a timed mode if the amount of time deviates from the reference value. The controller may have an initial training mode which measures the amount of time the ingredient feed mechanism is active establishes the reference value based upon the amount of time the ingredient feed mechanism is active.
