Definitions
- Beverage dispensing systems are typically used in beverage dispensing establishments for efficiently dispensing large quantities of beverage.
- beverage dispensing systems are used to dispense carbonated alcoholic beverages such as draught beer and cider
- non-alcoholic beverages such as soft drinks and non-carbonated beverages such as wine and fruit juice may be dispensed using a beverage dispensing system
- Beverage dispensing systems are mostly for professional users such as in establishments like bars, restaurants and hotels, however, increasingly also for private users such as in private homes
- beverage kegs typically dispense beverage provided in large beverage kegs. Such beverage kegs may hold 20-50 litres of beverage for a professional beverage dispensing system for allowing typically 50-100 beverage dispensing operations before needing to exchange the beverage keg.
- beverage kegs are made of solid materials such as steel and re-filled a number of times Inbetween each filling the beverage kegs are carefully cleaned Insufficient cleaning may lead to unhygienic beverage kegs, which may in turn lead to health problems for the beverage consumer
- beverage kegs are made collapsible for single use only due to the above hygiene concern.
- beverage dispensing system using collapsible beverage kegs is the DraughtMasterTM system provided by the applicant company
- Such beverage dispensing systems using collapsible beverage kegs typically have the beverage keg installed in a pressure chamber.
- a pressure fluid is allowed to enter the beverage keg in case of using a metal keg, or the pressure chamber in case of using a collapsible keg.
- the keg itself may be considered to be the pressure chamber
- the pressure fluid acts on the beverage and forces the beverage out of the pressure chamber
- a collapsible beverage keg is used, the beverage keg collapses while dispensing the beverage and the volume of the beverage keg is reduced corresponding to the amount of dispensed beverage
- the collapsible beverage kegs are preferably made of flexible and disposable material such as plastic.
- the tapping line leads to a tapping device typicaliy having a tapping valve and a tapping handle for allowing an operator to control the tapping valve and thereby the beverage dispensing operation.
- the operator such as a bartender or barmaid, uses the tapping device to control the rate of beverage dispensing.
- residual beverage will inevitably be left in the tapping line and in the tapping device.
- a layer of residual beverage may be formed inside the tapping line and tapping device. Such layers of residual beverage may solidify and eventually clog the tapping line and/or the tapping device, which will impair the beverage dispensing operation.
- the residual beverage will pose a hygienic problem
- the tapping line and the tapping device constitute areas where bacterial growth may be accelerated due to the presence of beverage, the large surface area in comparison to the beverage volume, the lack of sufficient cooling and the close proximity to the outside.
- Bacterial growth due to lack of hygiene in the tapping line and the tapping device may constitute a quality problem for the beverage consumer.
- crust formation of solidified beverage within the tapping line may occur. Therefore there is a need for technologies for cleaning the tapping line and the tapping device after a certain period of time or alternatively after a certain number of beverage dispensing operations.
- rinsing fluid or beverage may enter the tapping line selectively.
- Rinsing fluid is provided from a separate pressurized reservoir.
- the discharge valve includes safety features for avoiding mixing rinsing fluid and beverage.
- a cleaning and flushing cartridge for internal use is described
- the cleaning and flushing cartridge is installed in the pressure chamber similar to a beverage keg and dispensed similar to a beverage. It may however be advantageous to provide an external system for cleaning and flushing, which may be operated while a beverage keg or alternatively beverage is still accommodated inside the pressure chamber
- a method of detecting the operational mode of a beverage dispensing system comprising: a sealable pressure chamber to be shifted between a first open position and a second closed position, a coliapsible keg to be received within the sealable pressure chamber, a tapping line, at least during use connected to the collapsible keg, a fluid pressure source connected to the pressure chamber for pressurising the pressure chamber, a first detector having a pressure input for receiving fluid pressure from the fluid pressure source and a control pressure output, detecting whether the sealable pressure chamber is in the first open position or in the second closed position and, provided the sealable pressure chamber is in the second closed position, supplying a control pressure from the control pressure output, and a second detector having a pressure input for receiving fluid pressure from the fluid pressure source and a contra!
- the method comprising evaluating as a logical AND the control pressures from the control pressure outputs of the first and second detectors and determining the operational mode of the beverage dispensing system, the operational mode only to be accomplished provided both control pressures are supplied from the control pressure outputs of the first and second detectors
- pressure chambers have a detachable lid for accessing the interior of the pressure chamber when installing or removing a beverage keg
- Some pressure chambers may have a vertical orientation when in the closed position, and may be swung into a horizontal orientation when in the open position when the beverage keg is about to be changed Before opening the beverage keg, the pressurized air is normally iet out slowly to avoid injuries when opening the lid
- the pressure chamber is sealed and pressurized with pressure fluid, the volume of the coliapsible keg is reduced as the beverage is dispensed through the tapping line.
- the tapping line typically leads to a beverage tap for controlled dispensing of the beverage
- the fluid pressure source may comprise an air compressor or any other suitable device for generating a pressure fluid having a pressure suitable for beverage dispensing
- the first detector may supply pressure fluid from the control pressure output of the first detector when the pressure chamber is closed Consequently, no pressure fluid is supplied from the contro!
- the first detector may e g detect if the beverage container is swung into a vertical orientation and/or if the lid is applied
- the second detector likewise detects if a beverage keg is correctly installed in the pressure chamber and then supplies pressure fluid from the control pressure outlet of the second detector If no beverage container is installed of if the beverage container is falsely installed, i e not in fluid communication with the tapping line, no pressure fluid is supplied from the control pressure output of the second detector
- the logical AND evaluation should be understood to mean that the operational mode is not determined accomplished if none or only one of the first and second detectors supplies the control pressure from its control pressure output Only if both the first and second detectors supply the control pressure from their respective control pressure outputs, the operational mode is determined accomplished-
- the above control pressures and determination of the operational mode may preferably be used in combination with a safety system for preventing or at least discouraging the use of the beverage dispensing system when the beverage dispensing system is not in the operational mode
- control pressure i e a pneumatic signal
- the control pressure has surprisingly been found to be superior to an electrical circuit for determining the operational mode, since electrical components are not fail-safe in the present environment comprising beverage, cleaning fluids and flushing fluids
- a short- circuit caused by fluid intrusion into the electronic circuits may cause a failure of the electronic system and a complete loss of the logical system and thereby the safety system
- the safety system may be contemplated to include means for allowing the pressure chamber to be pressurized only if the operational mode is accomplished
- the enabling mode may be indicated by an indication signal, such as e.g a green light, a green signal plate or the like
- indication signals may preferably be located at a plurality of suitable locations, such as at the beverage tap and at the pressure chamber
- the first and second detectors may be connected in a series configuration or alternativety be connected to a AND pressure valve for generating an enabling pressure, provided the operational mode is accomplished
- no enabling pressure is generated if one of the detectors is not supplying the control pressure
- the enabling pressure is thus directly generated from the control pressure
- the control pressures are used to control an AND pressure valve
- An AND valve allows supply of pressure fluid if both the first and second control pressures are supplied Such valves are well known in the art.
- the enabling pressure may preferably be used for pressurizing the pressure chamber, thereby creating a fail-safe safety system When any of the detectors does not supply the control pressures, the pressure chamber cannot be pressurized
- a discharge valve may be provided between the beverage keg and the tapping line, the discharge vaive having a beverage dispensing position and a closed position, wherein the operational mode corresponds to the pressure chamber being pressurized, and the enabling pressure is used for causing the discharge valve to assume the beverage dispensing position.
- the discharge valve may prevent beverage from entering the tapping line by preventing fluid communication between the beverage keg and the tapping line if the beverage dispensing system is not in the operational mode
- the discharge valve may allow beverage dispensing by restoring fluid communication between the beverage keg and the tapping line.
- the discharge valve preferably uses the enabling pressure to assume the beverage dispensing position Without the enabling pressure, the closed position may be assumed by a counteracting spring or the like
- a rinsing cartridge may be provided in fluid communication with the tapping line, and a third detector having a pressure input for receiving fluid pressure from the rinsing cartridge and a control pressure output, detecting whether or not the rinsing cartridge is pressurized, and provided the rinsing cartridge is pressurized, supplying a control pressure from the control pressure output, wherein the method comprising evaluating as a logical AND the control pressures from the control pressure outputs of the first, second and third detectors and determining a rinsing mode of the beverage dispensing system is only accomplished provided all three control pressures are supplied from the control pressure outputs of the first, second and third detectors Cleaning and flushing should not be allowed to commence if the pressure chamber is not pressurized, i.e.
- a third detector may be used for detecting when the rinsing cartridge is pressurized, since rinsing cannot commence without a pressurized rinsing cartridge.
- the third detector may supply a pressure fluid from the control pressure output of the third detector when the rinsing cartridge is pressurized. Consequently, no pressure fluid is supplied from the control pressure output of the third detector if the rinsing cartridge is not pressurized
- the logical AND evaluation should be understood to mean that the rinsing mode is not determined accomplished if none or only one or two of the first, second and third detectors supply the control pressure from its control pressure outputs Only if all of the first, second and third detectors supply the control pressure from their respective control pressure outputs, the rinsing mode is determined accomplished.
- the above control pressures and determination of the rinsing mode may preferably be used in combination with a safety system for preventing or at least discouraging the use of the rinsing cartridge when the beverage dispensing system is not in the rinsing mode
- some embodiments may use two subsequent logical AND evaluations: In a first step the control pressure outputs of the first and the second detectors are evaluated as a logical AND for determining the operational mode, and in a subsequent step the result from the first step and the control pressure output of the third detector are evaluated as a logical AND for determining the rinsing mode
- the rinsing mode may be indicated by an indication signal, such as e g a red light, a red signal plate or the like
- an indication signal such as e g a red light, a red signal plate or the like
- Such indication signals may preferably be located at a plurality of suitable locations, such as at the beverage tap and at the pressure chamber, for avoiding attempts of performing any beverage dispensing operations when the rinsing mode has been determined
- the first, second and third detectors may be connected in a series configuration or alternatively be connected to an AND pressure valve for generating a rinse-enable pressure provided the rinsing mode is accomplished
- an AND pressure valve for generating a rinse-enable pressure provided the rinsing mode is accomplished
- no rinse-enabie pressure is generated if one of the detectors does not supply the control pressure.
- the rinse-enable pressure is thus directly generated from the control pressure
- the control pressures are used to control an AND pressure valve.

- a discharge valve may be provided between the rinsing cartridges and the tapping line, the discharge valve having a rinsing position, where the rinsing mode corresponding to the rinsing cartridge being pressurized, and the rinse-enable pressure is used for causing the discharge valve to assume the rinsing position.
- the discharge valve may prevent cleaning and flushing fluid from entering the tapping line by preventing fluid communication between the rinsing cartridge and the tapping line if the beverage dispensing system is not in the rinsing mode.
- the discharge valve may allow beverage dispensing by restoring fluid communication between the rinsing cartridge and the tapping line.
- the discharge valve is preferably using the rinse-enable pressure to assume the rinsing position Without the enabling pressure, the closed position may be assumed by means of a counter-acting spring or the like.
- the discharge valve has three positions: a rinsing position, a beverage dispensing position and a dosed position. The rinse-enable pressure, the enabling pressure and the spring cause the valve to assume the three above-mentioned positions.

- a rinsing fluid outlet 24 is provided at the bottom of the cleaning fluid cartridge 46 Rinsing fluid is in the present context understood to comprise any of the cleaning fluids and flushing fluids
- a rinsing line 25 connects the rinsing fluid outlet 24 to a rinsing connector 27 located at the side of the cleaning and flushing unit 20.
- a float valve 50 is provided inside the cleaning fluid cartridge 46 for avoiding pressure fluid in the cleaning fluid cartridge 46 to escape into the rinsing fluid outlet 24. The float valve 50 will permit liquids, i e. flushing and cleaning fluid, to flow out through the rinsing fluid outlet 24 and prevent gas, i e pressure fluid from flowing out through the rinsing fluid outlet 24.
- a set of flanges constituting a float valve support 52 will ensure that the float valve 50 is positioned in a secure closed state in the cleaning fluid cartridge 46 when no cleaning fluid is present in the cleaning fluid cartridge 46.
- a pressure fluid pipe 29 provides pressure fluid from the side of the cleaning and flushing unit to the upper interior part of the flushing fluid cartridge 36 to avoid any flushing fluid entering the pressure fluid pipe 29 when the flushing fluid cartridge 36 is filled.
- the cleaning and flushing unit 20 may be prepared by filling flushing fluid, i e. water, into the cleaning fluid cartridge 46 and the flushing fluid cartridge 36.
- the flushing fluid cartridge 36 is subsequently sealed from the cleaning fluid cartridge 46 by a flushing fluid cap 56,

- the cleaning constituent may be provided as a powder, liquid or paste, or a combination thereof, preferably in a specific metered amount or unit dose.
- the cleaning fluid cartridge 46 is sealed by a cleaning fluid cap 58
- Fig. 1 B shows the cleaning and flushing unit 20 of Fig. 1A when it has been installed in a beverage dispensing system (not shown).
- pressure fluid e g pressurized air
- the pressure fluid causes the flushing fluid in the flushing fluid cartridge 36 to enter the cleaning fluid cartridge 46 via the cartridge interconnection 40
- the flushing fluid leaves the flushing fluid cartridge 36 through the flushing fluid outlet 38 and enters the cleaning fluid cartridge 46 through the flushing fluid inlet 42, thereby causing the cleaning fluid in the cleaning fluid cartridge 46 to be expelled through the rinsing fluid outlet 24 and further via the rinsing line 25 and the rinsing connector 27
- the fluid flow directions are indicated in the figure by arrows.
- the rinsing connector 27 should be connected to the tapping line and the beverage tap of the beverage dispensing system, which it is desired to clean (not shown),
- the beverage tap (not shown) is located on the opposite end of the tapping line and typically located on a bar counter.
- the cleaning fluid is distinguished from the flushing fluid in the figure by small bubbles
- Fig 1C shows the cleaning and flushing unit 20 of Fig 1A when the flushing fluid cartridge 36 is empty and the cleaning fluid cartridge 46 is filied with flushing fluid.

- Fig 2B shows the cleaning and flushing unit 20' of Fig 2A when it has been installed in a beverage dispensing system (not shown)
- the pressure fluid entering the flushing fluid cartridge 36 via the pressure fluid pipe 29 causes the flushing fluid to subject the cleaning fluid cartridge 46' to a pressure force.
- the cleaning fluid is thereby expelled through the connector 60 towards the rinsing fine 25 while the cleaning fluid cartridge 46' collapses
- the cleaning fluid cartridge 46' will collapse onto the connector 60 and the cleaning fluid cartridge 46" will be pierced or ruptured by the connector 60.
- Fig 2C shows the cleaning and flushing unit 20 of Fig 1A when the flushing fluid cartridge 36 is empty and ruptured or alternatively pierced, allowing the flushing fluid to be expelled through the rinsing fluid outlet 24

- the control valve 124 will be further described in connection with Figs. 10-12-
- the cleaning and flushing fluid is provided from a centralized cleaning and flushing unit (not shown here but to be described below in Figs.
- the centralized cleaning and flushing unit may comprise a cleaning and flushing unit 20 as described above in connection with any of the figures 1-6, however it may be significantly larger, depending on the number of pressure chambers 10 and/or tapping lines/beverage taps it is intended to serve
- Fig. 9 shows a set of beverage dispensing base parts 66 for use with any of the above embodiments of the pressure chamber (not shown here but described in Figs, 7-8 and to be described below in Figs. 10-15 and designated reference numeral 10),
- a tapping line 68 is provided at the rear of the base part 66.
- a beverage container (not shown) may be installed on top of the base part 66 and connected to a beverage outlet 70.
- the tapping line 68 delivers beverage as well as cleaning and flushing fluid to the beverage tap (not shown).
- the base part 66 includes a discharge valve 72 for selectively allowing either beverage from the beverage outlet 70 or cleaning/flushing fluid from the first rinsing fluid supply 128 to be dispensed via the tapping line 68.
- the pressure chamber is pressurized via a pressure fluid pipeline 74 and a pressure fluid inlet 76. It is contemplated that the above embodiment of a base part 66 may also be used with the local cleaning and flushing units as described above in connection with Fig 7.
- Figs. 10 -15 show two specific embodiments of a centralized and local rinsing system 1 10, 1 16, respectively, having a safety system for controlling the rinsing and beverage dispensing.
- the safety system prevents rinsing from commencing if the pressure chamber 10 is not pressurized or if the discharge valve 72 is not in the rinsing position
- Figs 10-12 show a centralized rinsing system for a plurality of pressure chambers
- Figs 13-15 show a local rinsing system for one pressure chamber only
- the centralized and local rinsing system 1 10, 1 16 each comprises two identical pressure chambers 10, 10'
- Fig 10 shows a centralized rinsing system 110 in rinsing mode
- the centralized rinsing system comprises an air compressor 1 12, a first pressure chamber 10, a second pressure chamber 10', and a centralized cleaning and flushing unit 118
- the air compressor 1 12 is by a first pressure tube 136 connected to the first pressure chamber 10 via a primary safety valve 120 and a secondary safety valve 122
- the primary safety valve 120 allows compressed air to flow from the air compressor 112 towards the secondary safety vaive 122
- the secondary safety valve 122 allows compressed air to pressurize the pressure chamber 10 when the pressure chamber assumes the vertical orientation shown in Fig 7, which indicates that the first pressure chamber 10 is ready for beverage dispensing
- the secondary safety valve 122 prevents compressed air from pressurizing the first pressure chamber 10 when the pressure chamber 10 has assumed the horizontal orientation Any of the pressure chambers 10, 10' may be swung into their horizontal orientation when a new beverage keg is to be installed, e g when the original beverage ke
- the air compressor 1 12 Is further by a third pressure tube 140 connected to the centralized cleaning and flushing unit 1 18
- the cleaning and flushing unit 118 is further by a fourth pressure tube 142 connected to the control valve 124 so that a pressure will act on the control valve 124 when the rinsing unit 118 is pressurized
- the control valve 124 When the control valve 124 is subjected to pressure from both the cleaning and flushing unit 1 18 and the first pressure chamber 10, it will allow pressure fluid to act on a discharge vaive 72 and cause it to assume the rinsing and flushing position
- the discharge valve 72 is of the same type as the discharge valve 72 described above in connection with Fig. 9.
- the second pressure chamber 10' is by a second rinsing fluid supply 130 connected to the cleaning and flushing unit 1 18, separately in relation to the first pressure chamber 10.
- both of the discharge valves 72, 72' of the pressure chambers 10, 10' will assume the rinsing position if they are pressurized. This is to avoid beverage dispensing and rinsing from different taps at the same time, which would be a safety hazard since cleaning fluid may accidentally be confused with beverage.
- a switch may be provided on the cleaning and flushing unit 1 18 for selectively providing cleaning and flushing fluids to one of the first or second pressure chambers 10, 10'.
- both tapping lines 68 of the pressure chambers 10, 10' may be provided with cleaning and flushing fluids simultaneously.
- Fig, 1 1 shows the centralized rinsing system 1 10 in the beverage dispensing mode
- the air compressor 1 12 may deliver pressurized air to the cleaning and flushing unit 1 18.
- the pressurized air is prevented from acting on the control valve 124 via the fourth pressure tube 142 as the fourth pressure tube 142 is vented to the atmosphere in the beverage dispensing mode through a venting valve not shown in the drawings.
- the control valve 124 When the control valve 124 is not subjected to pressure from both the first pressure chamber 10 and the cleaning and flushing unit 1 18, the control valve 124 will prevent air pressure from acting on the discharge valve 72.
- Fig, 12 shows the centralized rinsing system 1 10 in a closed mode
- the closed mode implies that either the primary safety valve 120 and/or the secondary safety valve 122 is dosed, i.e that either the pressure chamber 10 is swung into the horizontal position or a beverage keg is not present inside the first pressure chamber 10 Pressurized air is prevented from pressurising the first pressure chamber 10 and consequently, the control valve 124 will not supply any pressure fluid to the discharge valve 72
- Fig 13 shows a local rinsing system 1 16 in the rinsing mode.
- the local rinsing system 1 16 comprises a compressor 112, a first pressure chamber 10 and a second pressure chamber 10'
- the cleaning and flushing unit 1 18 described above in connection with Figs. 10-12 has been replaced by a first rinsing cartridge 132 mounted in connection with the first pressure chamber 10 and a second rinsing cartridge 132' mounted in connection with the second pressure chamber 10',
- the first and second rinsing cartridges 132 and 132', respectively, may be of the type described above in connection with Figs. 1-7.
- the first pressure chamber 10 is connected to the first rinsing cartridge 132 via the second pressure tube 138 so that when the first pressure chamber 10 is pressurized, the first rinsing cartridge 132 is pressurized as well
- the first rinsing cartridge 132 is further connected to the discharge valve 72 so that when the first rinsing cartridge is pressurized, the pressure acts on the discharge valve 72 via the fourth pressure tube 142 so that the discharge valve 72 assumes the rinsing position. In the rinsing position, rinsing fluid is allowed to flow from the first rinsing cartridge 132 through the discharge valve 72 towards the tapping line 68',
- Fig. 14 shows a local rinsing system 1 16 in a beverage dispensing mode.
- the first rinsing cartridge 132 is simply removed from the first pressure chamber 10
- a check valve (not shown) prevents pressurized air from leaving the first pressure chamber 10 via the second pressure tube 138, Consequently, no pressurized air will act on the discharge valve 72, which causes the discharge valve 72 to assume the beverage dispensing position.
- the beverage dispensing position allows the beverage to flow through the discharge valve 72' towards the tapping line 68'.
- Fig. 15 shows a local rinsing system 1 16 in a closed mode.
- the closed mode for the local rinsing system 1 16 corresponds to the closed mode of the centralized rinsing system 1 10 and will therefore not be further discussed.
- Fig.16 is a schematic cut-through, close-up view of a discharge valve 72, as illustrated in the above drawings.
- the discharge valve 72 comprises a rod 174, which is located inside the coupling housing
- the ball-seal 176 is in the present embodiment not a part of the coupling housing 192, but part of the beverage container 168.
- the ball-seal 176 is received in the base part 186.
- the discharge valve 72 is operable between three possible positions, which constitute a first position, and opposite second position and an intermediate position, As will be described in greater detail below, the intermediate position constitutes the beverage dispensing position whereas the first and second positions constitute the rinsing position and the closed position, respectively.
- the ball-seal 176 is located in the base part 186 in a defined space between an inlet constriction 178 and an outlet constriction 180.
- the inlet constriction 178 and the outlet constriction 180 both include an opening or aperture for allowing beverage to fiow from the beverage container 168 via the inlet and outlet constrictions 178, 180 and further through the coupling housing 192 towards a beverage outlet 182
- Both the inlet constriction 178 and the outlet constriction 180 constitute valve seats, which the ball-seal 176 may seal against,
- the bali-seal 176 will either establish a seal against the inlet constriction 178 or the outlet constriction 180, or remain in the intermediate position, shown in Fig 16, which constitutes the beverage dispensing position.
- the coupling housing 192 accommodates the rod 174 and fits to the base part 186,
- the coupling housing 192 is fixated to the floor such that when the pressure chamber 10 and the beverage container 168 are swung or pivoted into the horizontal orientation, the coupling housing 192 including the rod 174 remains with the bottom wail, and the discharge valve 72 including the bali-seal 176 remains with the beverage container 168.
- the rod 174 and the coupling housing 192 may thus be made of rigid and non-disposable materials such as metal.
- beverage may flow from the beverage container 168 past the bali-seal 176 and through the beverage outlet 182.
- the beverage outlet 182 is in fluid communication with the tapping line.
- the base part 186 is sealed off by a laminate sealing at the outlet constriction 180
- the laminate sealing is broken by the rod 174 when installing the beverage container 168. This allows beverage to be dispensed from the beverage container 168
- the coupling housing 192, and thereby also the rod 174 is separated from the beverage container 168, the beverage, indicated by a shading in the figure, will exert a force on the ball-seal 176 pushing the ball-seal 176 against the outlet constriction 180 defining the closed position, i e. the second passive position, thereby sealing off the beverage container 168
- the ball-seal 176 is positioned between the inlet constriction 178 and the outlet constriction 180, allowing beverage to flow from the beverage container 168 past the ball- seal 176 and further through the beverage outlet 182 to the tapping line.
- the beverage container 168 is fitted with the base part 186, wherein the top part of the discharge valve 72 is received.
- the ball-seal 176, the inlet constriction 178 and the outlet constriction 180 are components of the base part 186.
- the rod 174 may be shifted towards the beverage container 168 or towards the beverage outlet 182 and tapping line 68.
- a spring 184 presses the rod 174 in the direction away from the beverage container 168 into the closed position.
- the discharge valve 72 is preferably used together with the safety system described in Figs. 10-15.
- the pressure chamber may be pressurized only when beverage dispensing is allowed, i.e. when a beverage keg 168 has been installed and the pressure chamber has been swung into vertical orientation.. Consequently, the pressure inside the pressure chamber may be used for applying an intermediate force onto the spring 184, holding the rod 174 in the beverage dispensing position shown in Fig. 16.
- the rod 174 moves towards the beverage container 168 into the rinsing position further described in Fig. 17.
- Fig. 17 is a schematic cut-through, close-up view of the same assembly shown in Fig. 16, with the discharge valve 72 slightly rotated around the vertical axis for disclosing a rinsing fluid inlet 190 and a rinsing fluid supply 128, which is not shown in Fig, 16, and the rod 174 in the rinsing position instead of the beverage dispensing position shown in Fig 16. It is shown that the rinsing fluid inlet 190 is located at the coupling housing 192. The rinsing fluid inlet 190 is used for performing rinsing of the discharge valve 72 and the tapping line A rinsing fluid may be introduced via the rinsing fluid inlet 190 and rinses the space within the discharge valve 72.
- the ball-seal 176 and the inlet constriction 178 establish a seal preventing rinsing fluid from entering the beverage container 168, however, allowing the rinsing fluid to flush and rinse the discharge valve 72 and the tapping line.
- rinsing fluid By opening the beverage tap when the rod 174 is in the rinsing position, rinsing fluid will flow out of the beverage tap and flush and rinse the discharge valve 72 as well as the tapping line and beverage tap (not shown)
- the coupling housing 192 interconnects the outlet constriction 180 of the discharge valve 72 and the beverage outlet 182,
- the rinsing fluid inlet 190 is attached to the coupling housing 192 as well, but in a position below a rinsing valve seat 196-
- a corresponding rinsing valve element 194 allows fluid communication between the rinsing fluid inlet 190 and the coupling housing 192.
- the rinsing valve element 194 contacts the rinsing valve seat 196 and prevents fluid communication between the coupling housing 192 and the rinsing fluid inlet 190. This is to prevent beverage and rinsing fluid from mixing when the rod 174 is in the dispensing position
- flushing fluid i.e. tap water
- rinsing fluid inlet 190 is introduced through the rinsing fluid inlet 190 to flush the discharge valve 72 and the tapping line so that residua! cleaning fluid is not dispensed with the beverage in the first beverage dispensing operation after rinsing
- Fig. 18 shows an alternative embodiment of the centralized rinsing system 110'.
- pressure fluid may be selectively provided to one of the control valves 124, 124'.
- pressure fluid is supplied only to the control valve 124' belonging to the second pressure chamber 10'.
- a switch may be used for this purpose Since both pressure chambers 10, 10' are pressurized, the discharge valve 72 belonging to the first pressure chamber 10 will assume the beverage dispensing position, and the discharge valve 72' of the second pressure chamber 10' will assume the rinsing mode.
- cleaning and flushing fluid may be supplied to the discharge valves 72, 72' of both pressure chambers 10, 10'.
- beverage and cleaning fluid may be dispensed simultaneously in the present embodiment and thus the present embodiment does not fulfil the highest level of safety since beverage and rinsing fluid may be accidentally mixed up by a careless operator
- the present embodiment does, however, bring slightly more flexibility to the rinsing operation and at the same time provides some basic safety requirements such as preventing the rinsing operation when the pressure chamber is opened and not pressurized.
