Embodiments described herein relate to systems and methods of extracting liquid from empty barrels. In one aspect, a method includes heating a barrel with less than about 10 ml of free liquid disposed therein to expand pores in the barrel. The method further includes applying, after the heating, a negative pressure to an interior of a vessel in which the barrel is disposed, such that an amount of liquid is extracted from the barrel. The method includes collecting, after the applying, the amount of liquid within a collection container. In some embodiments, collecting the amount of liquid includes pumping the liquid through a tube that is disposed between an outer surface of the barrel and the collection container. In some embodiments, heating the barrel is via a heated blanket wrapped around the barrel. In some embodiments, heating the barrel is via placing the barrel in an oven.

A dispenser head for in-line mixing and dispensing of beverages, which may be carbonated or nitrogenated. The dispenser head comprising a pump, a dilution mechanism, an additive mechanism, and outlet nozzle and optionally a regulation system. In use, the pump can pump concentrate liquid for the liquid product from a concentrate source to the dilution mechanism; the dilution mechanism can receive diluent liquid suitable for the liquid product from a diluent source, operable to mix the diluent liquid and the concentrate liquid and provide diluted concentrate liquid; and the additive mechanism can receive additive fluid for the liquid product from an additive source, to combine the diluted concentrate liquid and the additive fluid. The regulation system comprises a pump regulator means for regulating the quantity of concentrate liquid pumped into the dilution mechanism within the dispense period; a diluent quantity regulator means for regulating the flow of diluent liquid into the dilution mechanism; and an additive quantity regulator means for regulating the flow of additive fluid into the additive mechanism. Preferably, the dispenser head is a unitary device, which may be supplied attached to a vessel containing the concentrate.

A beverage dispenser for dispensing beverages and process may include a fluid container containing a fluid ingredient, a conduit fluidly connected to the fluid container, and an electrical conductivity sensor. The electrical conductivity sensor may be (i) fluidly connected to the conduit, and (ii) configured to sense an electrical conductivity of the fluid ingredient flowing through the conduit. The electrical conductivity sensor may further be configured to output (i) a first electrical signal in response to sensing an air bubble, and (ii) a second electrical signal in response to not sensing an air bubble.

The apparatus includes a reservoir (2), a liquid source (1), a carbon dioxide source (12), a non-return valve (8), a carbonating vessel (7) to receive liquid from the reservoir (2) via the non-return valve (8), a gas inlet (15) to receive carbon dioxide from the carbon dioxide source (12), and a dip tube (16) to withdraw carbonated liquid from the carbonating vessel. A pressure relief valve (20) vents gas from the carbonating vessel (7), and a dispense valve (18) controls the supply of carbonated liquid from the dip tube (16) to a dispense outlet (17). A charge control valve (14) controls the supply of carbon dioxide to the carbonating vessel (7). The apparatus has the following modes of operation-charge: the dispense valve (18) is held closed while the charge control valve (14) is opened to admit a charge of carbon dioxide into the carbonating vessel (7); dispense/refill: the dispense valve (18) is opened to dispense carbonated liquid while liquid flows into the carbonating vessel from the reservoir (2) via the non-return valve (8). The carbonated beverage can
