-
Fig. 1 shows adispensing device 1 according to the invention. Thedispensing device 1 is adapted for dispensing carbonised beverage, such as for instance beer, ciders, soft drinks etc. - The
dispensing device 1 comprises abeverage container 2 having acontent 25 of agas 3 and abeverage 4, thebeverage 4 having a predetermined gas content, for instance a CO2 content. The gas content is set by the brewery for the specific beverage so that beverage, when being dispensed, has the intended taste, feel, texture and foam generation. The predetermined gas content set by the brewery is the pressure of equilibrium for the specific beverage. - Furthermore, the
beverage container 2 comprises anextractor tube 5 and adispense head 6 adapted to be coupled with theextractor tube 5. Agas source 7 is connected with thedispense head 6 for delivering a gas to thebeverage container 2 via thedispense head 6. Thebeverage container 2 may be made of metal, such as stainless steel. - During operation of the
dispensing device 1, thegas source 7 supplies pressurised gas, such as CO2 or other suitable gasses, via thedispense head 6 to the top of thebeverage container 2 in order to displace the beverage. When the dispensing tap (not shown) is opened, the CO2 will start displacing the beverage from the top of thebeverage container 2, causing the beverage at the bottom of thebeverage container 2 to flow via theextractor tube 5 into a flow channel in thedispense head 6 and further into thedispensing line 15. - The extractor tubes and dispense heads are inter alia referred to as A-Systems, G-Systems, M-Systems, S-Systems, D-Systems, U-Systems and L-Systems, and their design and function are well-known and will not be described in detail here.
- These extractor tubes and dispense heads may be divided into two types, the well types and the flat types. The well types are characterised in that the dispense head is adapted to be inserted into a collar of the extractor tube, and the flat types are characterised in that the dispense head is adapted to be slid onto a flange of the extractor tube.
- All the dispense head systems mentioned above are adapted to open a double valve (i.e. a concentric gas valve and beverage valve) of the extractor tube by a piston of the dispense head being displaced downwards after being connected with the extractor tubes for opening the valves. The piston may displace the valves directly or may displace an intermediate piston arranged between the valves of the extractor tube and the dispense head.
- According to the invention, a
temperature sensor 8 is arranged for directly or indirectly measuring a temperature of thecontent 25 in thebeverage container 2. Furthermore, thedispensing device 1 comprises apressure regulator 9 having acontrol unit 10, thepressure regulator 9 being fluidly connected to thegas source 7 and the dispensehead 6, saidtemperature sensor 8 being connected with thepressure regulator 9, whereby thecontrol unit 10, on the basis of the measured temperatures of thecontent 25, regulates the gas pressure delivered to the dispense head and thereby to thebeverage container 2 via control of thepressure regulator 9. - By measuring the temperature of the content in the beverage container, the pressure of gas in the beverage container may be calculated and established. Hereby it is possible to regulate the gas pressure of the gas to be delivered to the beverage container during dispensing, so that the gas pressure substantially corresponds to the predetermined gas content of the beverage, i.e. the pressure of equilibrium for the specific beverage. The pressure regulator hereby ensures that the beverage will not be over-carbonated due to an excessive gas pressure being delivered to the beverage container. Also, the pressure regulator ensures that the beverage will not lose its gas content due to an insufficient gas pressure being delivered to the beverage container. Accordingly, the dispensing device according to the invention ensures that the beverage being dispensed substantially has the intended taste, feel, texture and foam generation.
