  • Patent number: 8998035
    Abstract: A system, method, and apparatus are disclosed for controllably dispensing a liquid beverage concentrate for use in dispensing a beverage. The beverage may contain liquid beverage concentrate in combination with a liquid dilution ingredient such as water and may also include one or more additional ingredients. This system, method, and apparatus provides more precise control of the quantity of beverage concentrate dispensed by operating a pump used to dispense the concentrate based on the number of pulses of concentrate dispensed. A calibration is made to determine the measure of concentrate in each pulse. This volume per pulse is recorded and stored in a controller to controllably dispense a precise volume for a specific type of concentrate based on a predetermined recipe retained in the controller for each drink, type, and volume of the finished beverage.

  • Patent number: 8726789
    Abstract: A system as disclosed herein uses a cold or unheated water source such as a reservoir or a pressurized inlet feed line, and a heated water reservoir. The unheated water reservoir is pressurized with a pressurizing apparatus communicating with the unheated water reservoir. Such a pressurizing apparatus may include an air pump, bladder or piston arrangement as well as other pressurizing apparatus. The pressurizing apparatus is controllable to push water from the unheated water reservoir to the heated water reservoir.
