Abstract
A unit for dispensing beverage has one or more pressure vessels 4 each having an outlet 11 for communication to a dispensing tap 15. Each vessel 4 accommodates a flexible bag 18 containing the beverage having gas in solution. The vessels 4 are pressurised through connection 16 by an air compressor in the unit or from an existing fluid line and this pressurisation serves to ensure dissolution of the gases in the beverage and also to expel the beverage from the bags 18. The beverage is normally sealed in the bags prior to loading into the pressure vessels and the pressure of dispensing may burst a membrane in the port 19 to permit the flow of beverage from the bag. Alternatively the coupling of the pipe 20 with the port 19 may break the membrane for dispensing. There is a refrigeration system 9 with cooling coils 7. <IMAGE>

Description
5 8 9 <a this invention relates to a unit for dispensing beverage containing gas in solution and is primarily concerned with the provision of a compact unit which is suitable for use in outlets such as bars or clubs which have relatively sljbw sales 5 of the beverage.
In the brewing industry there are many occasions where a retail outlet for fermented beverages such as beer, ale, lager or stout containing gas in solution has such a low through-put of the beverage on a daily or weekly basis that a bulk 10 dispensing system is not justified to provide Che beverage in draught form. In a bulk dispensing system for fermented beverage it is well known to maintain the beverage under pressure for dispensing by an external source of the gas in solution; this gas is usually carbon dioxide or a mixture of 15 carbon dioxide and nitrogen, the use of the latter mixed gases
is preferable, particularly for stout, where the nitrogen content adds considerably to the characteristics of the beverage and also to the foam head which may be formed during dispensing of the beverage (if the gases are released from 5 solution by subjecting the beverage to cavitation in conventional manner). For outlets having a low through-put the expense and accoosnodation of a cask or keg of beverage cogetber with a conventional draughting system comprising a source of gas such as carbon dioxide and nitrogen is unlikely 10 to be justified. In an attempt to overcome this problem it has hitherto been proposed (for example by the disclosure in our U.K. Patent No. 1,588,624) to provide beverage in a small package or container (such as a bottle or carton) in which the beverage contains a gaseous mixture of carbon dioxide and 15 nitrogen and to excite the beverage (for example ultrasonically) to release some of the nitrogen gas and provide the beverage with characteristics similar to those which are to be expected from the beverage in draught form. While this technique is appropriate for low through-put trade outlets and 20 off-sales and provides a beverage having substantially the same
4
quality and characteristics as a similar beverage draughted from a bulk systsn, there is nevertheless a requirement for a compact unit by which beverage can be dispensed as by a draught system from a container in volumes greater than the 5 aforementioned package system but less than the bulk system. It is an object of the invention to satisfy the above requirsment in which the container progressively empties on denar.d, the characteristics of the beverage and its gaseous content are maintained substantially constant throughout the 10 emptying of the container without the admission of gas to the container, and the unit is suitable for use in low through-put outlets where there may be a requirement for dispensing of, say, ten litres of the beverage daily. With such a low through-put it will be realised that the dispensing unit must 15 be relatively simple in operation, inexpensive to manufacture and of a compact nature for mounting somewhat unobtrusively in a bar or counter.
According to the present invention there is provided
a compact unit Tor dispensing beverage containing gas in solution which comprises a pressure vessel having a chamber and an outlet communicating with a dispensing tap; a flexible bag containing the beverage and gas uhich is to be dispensed, said bag being housed in the chamber; means for pressurising the chamber of the pressure vessel with fluid under pressure to apply pressure to the bag Cor re-establishing a desired equilibrium of the beverage prior to dispensing so that gas uhich has come out of solution subsequent to the filling of the bag can be re-dissolved into the beverage and for dispensing the beverage from the bag, in which the pressure vessel is openable for the chamber to receive the bag and its contents as a uhole and said bag is delivered to the vessel in a sealed condition, and wherein coupling means is provided for connecting an outlet port in the bag in fluid flow communication uith the outlet of the pressure vessel, the coupling means comprising a flexible tube and a tubular socket component which receives a tubular spigot component to provide a sealed fluid connection, said coupling means being arranged to facilitate the coupling of the bag to the pressure vessel prior to the bag being fully loaded into the pressure vessel.
Preferably the compact unit of the present invention has at least two of the pressure vessels each with a chamber having an outlet for connection with the dispensing tap and a selector valve is provided for optionally opening and closing fluid flow communication between each of those outlets and the tap. Each chamber
of the pressure vessels will house one of the flexible bags containing the beverage and gas which is to be dispensed so that the unit can accomodate two or rare of the bags with the outlet ports in the bags in fluid flow cocnnunicatioa (by way of the coupling means) with the outlets of the respective pressure vessels. With two or more such pressure vessels and bags, the means for pressurising is arranged to permit each pressure vessel to be optionally pressurised for establishing the desired equilibrium in, and for the dispensing of, the beverage in the bag of that vessel.
By the present invention the or each pressure vessel (and preferably cwo such vessels are provided) will accooandate a bag containing the beverage and gas or gases which are to be dispensed by pressurisation within the vessel (but externally of the bag) to dispel the beverage through the dispensing tap. In the case of fermented beverage such as stout which contains both carbon dioxide and nitrogen in solution, the dispensing tap will usually incorporate an apertured plate by which the beverage is subjected to cavitation for release of
some of the nitrogen to assise in developing the characteristics for the head on the draught beverage. Consequently sealed flexible bags charged with the beverage and gases (the beverage content preferably being in the range 2.5 to 10 litres) can be transported and stored independently of the dispensing unit and loaded into the unit as required.
Prior to such loading a proportion of the gas or gases in the beverage will come out of solution into a headspace; the beverage, if dispensed in this condition, will have different, less preferable, characteristics as to appearance, taste (quality) and mouthfeel as compared to the beverage when dispensed with the preferred quantity of gas dissolved in it. Bearing this in mind, the pressurisation of the pressure vessel serves two important functions; firstly to ensure that the gas or gases which may be released from the beverage prior to the bag being loaded can be re-dissolved before dispensing and secondly to provide a pressure for dispensing which maintains the gases in solution as the bag collapses whilst being emptied. It is envisaged that a bag may have to be pressurised within a pressure vessel for a few hours to achieve

sufficient: dissolucion of Che gases Co ensure ChaC Che beverage is suiCable for dispensing; ic is for chis reason ic is preferred ChaC Che unic has Cwo or mace pressure vessels so ChaC Che beverage in a bag in one of Che vessels can be available for dispensing while beverage in a bag in Che oCher vessel or vessels is undergoing pressurisaCion Co render ic suiCable for dispensing in sequence as Che bag in Che firsC mentioned vessel empties and ChaC vessel has Co be re-loaded.
The flexible bags may be of a standard form which are well known in Che liquid food or beverage trade so ChaC Chey may be of a metallised plastics maCerial (such as Che "Liqui-Box" multi-ply bags marketed by GorrugaCed Products Limited), or such non Coxic flexible maCerials ChaC are relacively impermeable to gases.
Although Che presenC invention may be applied Co gasified beverages of a non-fermented nature, such as carbonated soft drinks, ic was particularly developed for use wich fermented beverages. The invention may convenienCly therefore be considered in its application Co a stout in which mixed niCrogen and carbon dioxide gases are essenCial constituents
for providing Che desired characteristics of the beverage and ics foan head when dispensed (where Che carbon dioxide effectively provides Che volume of Che head and Che nicrogen is believed Co sCabilise a small bubble size which is preferred). As previously mentioned, some of Che mixed gases will cane out of solucion prior Co Che bag being loaded in Che or a pressure vessel and commercially ic is important that Che time for the gases to redissolve (when the vessel is pressurised) is reduced to a minimum, say less Chan six hours for a low through-put ouCleC where each bag may have a beverage concent in Che range of 2.5 Co 5 litres. Dissolucion of Che gases is promoted by cooling the beverage and this cooling can be achieved by storing the bags in a cool box or refrigerator prior Co loading them into.a pressure vessel. Preferably however the compact unit includes means for cooling the bag or bags in its respective pressure vessel so that the beverage is cooled while it is pressurised within Che vessel. The preferred cooling serves two purposes, firscly to increase the rate aC which Che gases will be re-dissolved in the beverage
io and secondly to ensure that the beverage will be dispensed at an acceptable temperature for consumption - this temperature is usually in the range of 8°C to 129C. The cooling is preferably achieved by use of a thermostatically controlled refrigeration system in the unit. Preferably the cooling of each bag is separately controlled.
Experiments indicate that for dispensing purposes and also to achieve acceptable rates of dissolution of the gases in fermented beverage, the pressure vessels will usually have to withstand pressurisation to the range of 30 to 55 p.s."i. (absolute) (2.0 to 3.7 bats) and the pressure vessels must be capable of withstanding these pressures with an acceptable safety margin. The strength requirement for the or each pressure vessel is comparable to that of a domestic pressure cooker manufactured in accordance with British Standard 1746 -1977. Accordingly, the or each pressure vessel may consist of
a i two drawn container parts of aluminium or stainless steel appropriately anodised (to alleviate corrosion) and with a bayonet fitting between these two parts. A self-sealing ring will usually be provided between the two parts to maintain gas tightness. The outlet from the or each pressure vessel is preferably located substantially at a lowermost position in that vessel, probably in the base of the vessel (this should ensure that as much beverage can be extracted from the bag as is possible and it will also facilitate flushing and cleaning of the outlet). Each pressure vessel will also include a pressurising medium connection and preferably this is located at a low position, say through the base, of the vessel so that the vessel container part which may constitute a lid is free of pipework and easily removed for loading a bag.
Pressurisation of the or each pressure vessel can be achieved from a source within the unit, such as an electrically operated air compressor. Alternatively the pressurisation can be achieved from a source which is external to the unit such as
i 2
a pressurised line of carbon dioxide or air which may be available on the premises where the unit is to be installed. The possibility of using water pressure is also envisaged. The pressure vessel or vessels will usually have safety relief 5 valves and an associated pressure control valve by which the or each vessel can be individually pressurised or de-pressurised. Preferably the safety valve and port through which the vessel is to be exhausted (de-pressurised) are located at positions where beverage is unlikely to enter than 1q and where they are not likely to be obturated by the tag. The pressure vessel or vessels may be orientated in the unit in a Banner which is convenient for installation of the unit in a bar or club environment so that the or each vessel may be upright and openable to provide top loading (loading from 15 above) of the bags or horizontal and openable to provide front or side loading of the bags or inclined, say at 45°, as convenient.
Preferably the pressurisation of the or each vessel is variable from high pressure (to expedite the rate of
13
dissolution of the gas into the beverage prior to dispensing) and low pressure (for dispensing purposes). The conversion from high to low pressure can be automatic under time control if required.
The sealed outlets from the bags preferably comprise membranes which are intended to be broken or cut to permit dispensing of the beverage through those ports. In a preferred arrangement the manbranes are of predetermined strength so that they burst under the pressure differential which is developed across them when the dispensing tap is initially opened and the bags are externally pressurised. In a further arrangement the menbrane may be cut off immediately prior to the bag being connected in fluid flow communication with the outlet of the vessel. In a still further arrangement the membrane may be pierced by the coupling means during sealed connection of the bag to its respectively associated vessel
The insertion of the tubular spigot component into the socket component can cause the membrane to be pierced as aforementioned. In this latter arrangement it is preferred that the membrane is carried by the tubular spigot with the bag and that the socket component carries a tubular needle which is protected by the wall of the socket and which pierces the membrane during engagement of the spigot with the socket.
One embodiment of a unit for dispensing beverage containing gas in solution and constructed in accordance with the present Invention villi now be described, by way of example only, with reference to the accompanying illustrative drawing in which:
lis
Figure 1 diagranmatically illustrates a side elevation of the' unit in pact section, and
Figures 2 and 3 respectively illustrate alternative coupling means for effecting a fluid flow 5 connection between sealed outlet ports in bags and outlet ports of pressure vessels within which those bags are accommodated.
Toe unit for dispensing beverage containing gas in solution as illustrated is intended to be of a compact 10 structure so that it is readily portable, as a whole, to a site such as a bar or club where the beverage is to be retailed; the unit is intended to be capable of installation and operation by unskilled personnel and to be used in conditions where a low throughput of the beverage is required, say of the 15 order of 5 to 10 litres daily.
The unit illustrated is particularly suitable for use with fermented beverages and was developed for dispensing draught stout containing carbon dioxide and nitrogen gases in solution to the extent that at 15°C and atmospheric pressure,
1®
one volume of the stout contains carbon dioxide which is present in the range 0.8 to 1.8 volumes and contains nitrogen which is present in the range 0.015 to 0.035 volumes.
The unit has a casing within which are housed two 5 generally cylindrical pressure vessels 2 and 3. the vessels 2 and 3 are upstanding and constructed similarly to conventional domestic pressure cookers in accordance with British Standard 1746 - 1977 to comprise a body part 4 and a lid 5 which is secured to the body part through a bayonet fitting between 10 co-operating flanges 6 of the two parts. The body parts 4 are encircled by refrigeration cooling coils 7 and insulated within the casing 1 by appropriate foam plastics material 8. The cooling coils form part of a refrigeration system 9 by which the temperatures of the two pressure vessels are individually 15 thermostatically controlled. The refrigeration system 9 is capable of maintaining the two pressure vessels within a temperature range of 8°C to 12°C.
In the flat base 10 of each pressure vessel is located an outlet 11; the outlets 11 conaunicate through passages 12 with 2 0 a selector valve 13. The valve 13 permits either one of the
two passages 12 to communicate with a conduit 14 to a dispensing tap 15 whilst the other passage 12 is closed to such communication. The tap 15 can be mounted on the casing 1 or remote from the casing, say in the manner of a conventional bar fitting. The tap may be of a conventional form comprising an apertured plate through which the stout is to be dispensed and subjected to cavitation (which causes release of the mixed gases to assist in the development of a head on the stout).
Located in the base 10 of each pressure vessel is a pressure medium port/connection 16 by which gas under pressure can be admitted into either or both pressure vessels and also either or both pressure vessels can be exhausted. The pressurised gas supply may conveniently be taken from an existing carbon dioxide or air pressure line in Che premises where the unit is installed; alternatively the trait may incorporate an air compressor (not shown).
Pressure control valves 16<a are provided for individually pressurising or exhausting the respective pressure vessels. If required, a pressure regulator can be provided for
optionally pressurising the respective vessels to, say either 35 p.s.i- absolute (2.3 bars) or 55 p.s.i. absolute (3.7 bars). A safety pressure relief valve 17 is provided in the lid of each pressure vessel.
The stout which is to be dispensed is delivered to the unit in flexible bags 18 each of which accommodates five litres of the beverage together with the appropriate gaseous content:. With the lids 5 removed, the bags 18 are loaded into the bcdy parts 4 of the pressure vessels to be closely 10 accommodated within these vessels as indicated in Figure 1. However, prior to loading the bags and closing the lids of the pressure vessels through the bayonet fittings 6, it is necessary to effect a fluid flow connection between sealed outlet ports 19 in the bottoms of the bags with the outlets 11 15 of the respective pressure Vessels. The bags 18 nay be of a conventional metallised plastics structure in which the outlet port 19 is sealed by a plastics membrane. This membrane in the port 19 has to be broken to permit dispensing of the beverage. Die port 19 is intended to be connected in fluid 2 0 flow coamunication with the outlet 11 by way of a flexible pipe
. The pipe 20 communicates at one end to the vessel outlet 11 while its other end is intended to be connected to the outlet port 19 by means of the coupling shown in Figure 2 or Figure 3- To facilitate its coupling to the port 19, the pipe 5 20 may be extended from the body part 4 of its respective pressure vessel.
In the coupling arrangement shown in Figure 2 the outlet port 19 on the flexible bag comprises a tubular spigot 21 camunication between which and the beverage in the bag is 10 sealed by a membrane 22. The pipe 20 carries a tubular socket 23 uhich receives the spigot 21 in sealed manner (if required an 0-ring or similar seal can be provided between these co-operating components). With the socket and spigot thus connected the bag 18 is loaded into the vessel part 4 ensuring 15 that the pipe 20 is not kinked and that the outlet port 19 is lowennost. For dispensing purposes the pressure vessels will be pressurised by the admission of carbon dioxide through the connection 16 and the characteristics of the membrane 22 are selected so that the membrane will burst under the pressure 20 differential which develops when the tap 15 is initially opened
so foe dispensing (and the bag 18 is subjected to the dispensing pressure) and stout is thereby admitted into the pipe 20.
In the alternative coupling arrangement shown in Figure 3 the bag 18 again carries a tubular spigot 21 which, in this 5 instance, is closed by a wall or membrane part indicated at 24 towards the free end of the spigot. The spigot 21 is again received within a tubular socket 23 carried by the pipe 20 but in this instance the. socket 23 houses a tubular needle 25 which pierces the membrane 24 as the connection is made between the 10 spigot 21 and socket 23. Again this latter connection is intended to provide sealed cooiounication between the beverage in the bag 18 and the pipe 20. By ensuring that the needle 25 is housed within the socket 23 it will be seen from Figure 3 that the needle is protected to an extent that it is unlikely 15 to inadvertently pierce the wall of the bag 18.
Uhen the pressure vessels 2 and 3 have had their respective bags 18 loaded and the lids 5 are fitted and sealed, cooling of the beverage can commence by the refrigeration system 9. In addition, the pressure vessels are pressurised
2»
through the connections 16. Prior to the bags being loaded into the pressure vessels, some of the mixed gases originally in solution in the beverage will have come out of solution and be located in a headspace in the bag. To provide the beverage 5 with the desirable characteristics for consumption it is necessary that the emergent gases are re-dissolved in the beverage. This dissolution is achieved by subjecting the bags to pressure and cooling for a predetermined period, say five hours, before dispensing. When the beverage has re-attained 10 its equilibrium "in the bags 18, the selector valve 13 is adjusted to an appropriate one of the pressure vessels and dispensing effected through the tap 15 in conventional manner. Preferably the dispensing pressure within the pressure vessels is approximately 35 p.s.i. absolute (2.3 bars) 15 while a greater pressure within the pressure vessels is preferred to expedite dissolution of the released gases; accordingly the pressure may be regulated to, say, 55 p.s.i. absolute (3.7 bars) while the beverage in the pressure vessels is attaining its desired equilibrium condition for dispensing 20 and subsequently Che pressure can be reduced for dispensing.
2g
It may be that between thcee and six hours pressurisation at 55 p.s.i. absolute is cecomsended foe achieving a required degcee of dissolution and if required a timer can be incorporated Co control this sCage of the pressurisation following uhich 5 pcessurisation may be reduced automatically to Che prefecred dispensing pcessure.
Curing dispensing Che bag 18 will collapse as the beverage is withdrawn from it. When one of the bags is emptied its pressure vessel is exhausted by appropriate 1o adjusnaent of the pressure control valve 16a and thereafter a new charged bag can be loaded in that vessel. During this period beverage can be withdrawn from the second pcessure vessel while the beverage in the new bag aCtains its equilibrium condition ready to be dispensed in sequence. 15 Although Che flexible material of the bags 18 will have a considerable toughness, there is always the possibility ChaC a bag will leak or Cear while in ics pressure vessel. In this event it is merely necessary Co remove Che damaged bag, close and then pressurise the pcessuce vessel so ChaC Che bevecage 2 0 which lies in the. boCtom of che vessel is expelled through che
tap 15 by way of the outlet 11 - thereby avoiding the inconvenience of having to ladle the beverage from the body pact & of the vessel.
