  • Patent number: 9486107
    Abstract: A brewing system which uses an air pump to evacuate a dispensing line and a method of brewing in which a brewer includes an air pump to provide pressurized air at least at the end of a brew cycle to help evacuate moisture from a dispensing line. The brewing system includes a heated water reservoir which retains heated water for dispensing and a dispense line through which the water is dispensed. A vent is coupled to the reservoir. A controllable air pump communicates with the reservoir to controllably add air to the reservoir to drive water out of the reservoir. The vent is closed when the pump is used to add air to the system to allow for a build-up of air pressure in the reservoir and out through the dispense line. The controllable air pump controllably dispenses air into the upper portion. Both the air vent valve and air pump are controllably coupled to a controller.

  • Patent number: 9259115
    Abstract: The present disclosure includes an extraction assembly for use in an automatic espresso brewer. The extraction assembly includes components and methods for controllably extracting espresso beverage from a quantity of brewing substance. The components, assemblies, and methods facilitate improved control and operation of the extraction assembly and improve the reliability of the extraction assembly.

  • Patent number: 9161658
    Abstract: A beverage making apparatus including a housing containing a water system. The water system includes a heated water reservoir and a pour-in basin for receiving water. The pour-in basin is connected to a water pump which pumps water from the basin to the heated water reservoir. Water from the heated water reservoir is moved to a spray head for dispensing to a beverage brewing substance retained in either at least one of a pod format or a cartridge format. A pair of conductance probes are contained in the fill basin to indicate the status of water in the fill basin. The brewer is designed for use with multiple beverage making substance holders so that multiple beverage substance formats can be used with the brewer.

  • Patent number: 9113750
    Abstract: The present disclosure relates to a system for producing beverages or other food products which includes, generally and broadly, controllably dispensing water from the system for use in brewing. Water is introduced to a heated water reservoir (20) heating and subsequent use in a process such as brewing. A thermal expansion system (86) is provided to accommodate water which expands from the reservoir (20) as a result of the heating process. One form of thermal expansion system (86) may include a venturi device (88) which allows the accumulation of water which expands during the heating process and then returns the water to the flow of water during a brew cycle.

  • Patent number: 9091448
    Abstract: A system and method for controllably dispensing a predetermined volume of water at a predetermined temperature. The system and method include at least one heated water source and at least one second water source. Water is controllably dispensed from the heated water source and controllably combined with the controllably dispensed water from the second water source to produce a resultant predetermined volume of water at a resultant predetermined temperature. The system and method also includes controls and/or interfaces which allow a user to control the volume and temperature of water dispensed. The user may directly control the volume and/or temperature or may indirectly control the volume and temperature such as by introducing a control media, control selection, or recipe by which the user selects the choice but does not specify the details of the parameters associated with the choice.

  • Patent number: 8999421
    Abstract: A cartridge retaining device is disclosed for use with a beverage brewing apparatus. The device includes a base with a cover. A beverage making cartridge is placed within the base and the cover is positioned over the cartridge. Engagement of the cover over the cartridge in the base causes at least two probes, one above carried on the cover and one below generally carried on or proximate to the base to penetrate or otherwise open the cartridge. The device is structured to operate so that the cover probe penetrates the cartridge before the base probe opens a corresponding portion of the cartridge. The device is adapted for separate engagement with a brewer whereby heated water is dispensed from the brewer into the device for brewing a beverage retained within the cartridge and dispensing the brewed beverage from a lower section of the body of the device.

  • 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.
