Dispensing sequences for beverage mixture dispensing systems are disclosed. A disclosed method for operating a beverage mixture dispensing system includes flowing a first solvent from a first reservoir to a mixing area of the beverage mixture dispensing system, dispensing concentrated ingredients into the mixing area to combine the first solvent from the first reservoir with the concentrated ingredients to form an intermediate mixture, flowing the intermediate mixture to a mixing chamber of the beverage mixture dispensing system, flowing a sweetening liquid from a second reservoir to the mixing chamber, without flowing the sweetening liquid through the mixing area, to combine the sweetening liquid from the second reservoir with the intermediate mixture to form a beverage, and dispensing the beverage from the mixing chamber. A disclosed device is configured to execute this method. A disclosed computer-readable medium includes instructions for a device to execute this method.

Dispense sequence for a beverage mixture dispensing system

Systems and methods for reducing the overall current draw of a fluid mixture dispensing device are disclosed. A disclosed system includes a mixing area, a set of ingredient reservoirs, and a set of electromechanical valves. The set of electromechanical valves are in a one-to-one correspondence with the set of ingredient reservoirs, and fluidly connect the set of ingredient reservoirs and the mixing area during a respective set of dispense times. The system further includes a controller programmed to actuate at least two valves from the set of electromechanical valves to dispense, to the mixing area, at least two ingredients from the ingredient reservoirs associated with the at least two valves. The controller is programmed to actuate the at least two valves in sequence with partially overlapping dispense times and without overlapping opening times.

Electromechanical valve sequencing for fluid mixture dispensing devices

A cartridge and an associated beverage mixture dispensing system are disclosed. The cartridge is detachable from the associated beverage mixture dispensing system. The cartridge includes a casing and at least twenty ingredient reservoirs located within the casing and storing at least twenty respective ingredients. The cartridge also includes a dispensing interface for dispensing the at least twenty ingredients into the beverage mixture dispensing system. The at least twenty ingredient reservoirs include a first reservoir of a concentrated salt and a second reservoir of a concentrated food grade acid. The remaining ingredient reservoirs include additional concentrated ingredients. The beverage mixture dispensing system includes a solvent reservoir and a receiving interface for receiving the at least twenty ingredients from the cartridge. The beverage mixture dispensing system also includes a mixing area fluidly connected to the solvent reservoir and the at least twenty ingredient reservoirs.

Ingredients cartridge for a beverage mixture dispensing system

Systems and methods for sanitizing a fluid mixture dispensing system are disclosed. One system comprises at least one reservoir for storing a substance, a mixing area, and a controller. The controller is programmed to cause the system to execute a mixing cycle and a cleaning cycle. During the mixing cycle the substance is dispensed from the at least one reservoir to the mixing area to prepare an ingestible fluid mixture. During the cleaning cycle, the substance is dispensed from the at least one reservoir to the mixing area to sanitize the mixing area.

Sanitizing systems and methods for fluid mixture dispensing device

A fluid mixture dispensing system using a membrane to seal multiple reservoirs is disclosed. The multiple reservoirs each contain a respective ingredient. The reservoirs are coupled to respective orifices in a plate. The respective ingredients are dispensable via the respective orifices. The membrane seals the respective orifices. The ingredients are dispensed into one or more channels formed between the membrane and the plate. In specific embodiments, the membrane is an integral part of a cartridge which contains the multiple reservoirs. In specific embodiments, the cartridge includes an inlet and an outlet. A solvent flows from the inlet to the outlet through the one or more channels, and the ingredients are dispensed into the solvent in the one or more channels.

Membrane for reservoir seals in fluid mixture dispensing system

Ingredient dispensing systems and methods in a fluid mixture system using a monitored chamber pressure are disclosed. One system includes a chamber, an inlet to the chamber, a set of ingredient reservoirs, in the chamber, storing a respective set of ingredients and sealed by a respective set of valve, a pressure source, and a controller. The system is programmed to set a pressure of the chamber using the pressure source and the inlet to the chamber. The system is also programmed to dispense, using the pressure, at least two ingredients from the respective set of ingredients by actuating at least two valves from the respective set of valves.

Ingredient dispensing in a fluid mixture system using monitored pressure

Fluid mixture dispensing systems, devices and methods are disclosed. A device includes a set of pressurized ingredient reservoirs, a mixing area configured to receive at least one ingredient from the set of pressurized ingredient reservoirs, a pressure source, an accumulator chamber, a set of valves, and a controller. The controller is programmed to operate the set of valves to pressurize the accumulator chamber using the pressure source. The controller is further programmed to operate the set of valves to set a pressure in at least one of the set of pressurized ingredient reservoirs using the accumulator chamber.

Pneumatic system for fluid mixture dispensing device

In some embodiments of a fluid dispensing system: (1) two or more mixing channels are fluidly connected to (a) a mixing chamber fluidly connected to a dispenser, (b) a particular two or more solvent reservoirs, and (c) a respective one or more ingredient reservoirs, wherein each of the ingredient reservoirs is configured to dispense into a respective one of the mixing channels; and (2) a controller is programmed to receive a request for a fluid mixture, and, in response control the system to: mix, in the mixing channels to form an intermediate fluid mixture, a respective predetermined amount of solvent from each of the particular solvent reservoirs and a respective predetermined amount of the ingredients from some of the ingredient reservoirs; flow, to the mixing chamber and then to the dispenser, the intermediate fluid mixture; and dispense the requested fluid mixture (including the intermediate fluid mixture) via the dispenser.

Systems and methods for dispensing fluid mixtures

Ingredient dispensing systems and methods are disclosed. A disclosed system includes an ingredient reservoir and an electromechanical valve configured so that, when the electromechanical valve is activated, an ingredient is dispensed from the ingredient reservoir. The disclosed system also includes a current sensor configured to measure a current draw of the electromechanical valve. The disclosed system also includes a controller programmed to sample the current draw from the current sensor and to detect a dispense error of the electromechanical valve based on the sampled current draw.
