A method of selecting and dispensing a custom beverage in a contactless manner using a mobile electronic device. The method includes launching a microsite on the mobile electronic device. The method further includes receiving a beverage selection via the microsite on the mobile electronic device, and receiving a selection of a volume of the custom beverage to be dispensed via the microsite. The method further includes generating a QR code via the microsite, wherein the QR code corresponds to the beverage selection and the volume selection and displaying the QR code on a display of the mobile electronic device such that when the QR code is read by a reader of a beverage dispenser, the selected beverage is dispensed in the selected volume based on the QR code.

A carbonated beverage dispenser includes a tank to store carbonated water, a carbon dioxide source, and a release valve configured to release gas from the tank. The release valve may be actuated to mix the contents of the tank to increase the temperature homogeny and carbon dioxide homogeny in the tank. The tank may include sensors to monitor the temperature of the water and the amount of carbon dioxide dissolved therein.

A beverage mixing and dispensing system and a dispensing font device and/or dispensing tap configured to dispense a drink (D) from a mixture of at least a first main liquid (F.sub.1) and of a second liquid (F.sub.2) by use of one or more electrical pumps, one or more propellants, one or more regulators, one or more valves, one or more gas or liquid flow regulators and one or more control units operatively connected to enable operation and flow of liquids and propellants from one or more containers containing the liquids when dispensing the drink (D) via one or more beverage dispensing font devices and/or dispensing taps.

A carbonation device for beverages includes a carbonation tank to receive a beverage to be carbonated and carbon dioxide so as to generate a carbonated beverage, carbonated with the carbon dioxide, and a dispensing device in fluid communication with the carbonation tank to dispense, through a duct, the carbonated beverage to a container for carbonated beverages, the carbonated beverage flowing along the duct in a flow direction. The carbonation device further includes a carbonation sensor associated with the duct and having a radiation source to generate a radiation which strikes the duct along an irradiation direction incident to the flow direction. The carbonation sensor also includes a first photodiode placed on the irradiation direction from a side opposite to the radiation source with respect to the duct, or as an alternative, a second photodiode placed along a diffusion direction substantially orthogonal to the irradiation direction.

The invention discloses a soda machine with automatic gas filling and residual amount detection functions and a use method thereof. Compared with the prior art, the soda machine is safer to operate, cannot carry out automatic gas filling under the condition that the operation of the soda machine is not standard and can only carry out manual gas filling by a user under a special condition, so that the safety is higher; and meanwhile, the amount of residual carbon dioxide gas can be measured in real time according to the weight of the carbon dioxide gas cylinder, so that the user can conveniently prepare the standby carbon dioxide gas cylinder in time, and more convenience is achieved.

On-the-go carbonation applications, devices and methods are provided, which enable carbonating and enhancing liquid content in various containers, such as drinking bottles, in relation to users' preferences and activity patterns. Devices include a sealed container holding a gas canister, an actuator configured to release gas from the gas canister and break a seal of the sealed container, and a gas passage configured to deliver the released gas, optionally with flavoring and/or supplement additivesinto the liquid. Various configurations of the devices are provided to yield predefined carbonation and mixing of additives by simple actuation. Disclosed methods of carbonation enable configuring the device to be portable and attachable to various types of liquid container and monitor the usage of the devices. Applications provide users with suggestions for further use of the on-the-go carbonation device, in relation to the monitored use.
