ABSTRACT:
An electronically controlled ingredient dispensing system in hot or cold vending machines uses a voltage ramp generator and a volume controller for correlating a quantity of dispensed ingredients with the voltage ramp output. Circuit elements are provided to latch-in circuits corresponding to each ingredient after a coin triggered relay switch and beverage selection switches are actuated. A voltage comparator circuit functions to compare a timing circuit voltage of increasing magnitude with a manually variable reference voltage (indicative of ingredient quantity) and activates an ingredient dispensing mechanism when the compared voltage reaches a preselected value and deactivates the dispensing mechanism when the voltage reaches a preselected higher value. Further circuit elements are provided to increase the quantity of dispensed ingredients upon activation of an extra ingredient selection switch.
