Abstract
A system for dispensing and controlling the concentrate of a juice product in which the product is made up of a juice concentrate and water. The concentrate is dispensed by pump operation and the water is dispensed by solenoid operation. The system basically provides for the control of the solenoid and the pump and for the initiation of a dispensing cycle so as to initiate operation of the solenoid and pump substantially at the same time. A timer responds for operating the solenoid and pump over a preselected dispensing period. The control of the pump to provide concentration control is provided by a speed control circuit having multiple selectable positions for providing multiple pump speeds so as to in turn provide variable concentration of the final dispensed juice product.
