Definitions

  • the present invention relates to a method of dispensing carbonated beverage, a collapsible beverage container and a beverage dispensing system.
  • 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 carbonated beverages such as soft drinks 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 containers typically 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 container.
  • Conventional beverage containers are made of solid materials such as steel and refilled a number of times.
  • beverage containers have been made collapsible and for single use only due to hygiene concerns when refilling solid beverage containers.
  • An example of a beverage dispensing system using collapsible beverage containers is the DraughtMasterTM system provided by the applicant company.
  • Such beverage dispensing systems using collapsible beverage containers typically have the beverage container installed in a pressure chamber.
  • a module for a modular beverage distribution system comprises a frame, a pressure chamber and connectors for receiving pressure fluid and for supplying the pressure fluid to the pressure chamber and to the neighbouring module.
  • the system has a separate rinsing line.
  • rinsing fluid or beverage may enter the tapping line.
  • Rinsing fluid is provided from a separate pressurized reservoir.
  • the discharge valve includes safety features for avoiding mixing rinsing fluid and beverage.
  • WO 2010/029122 a method of cleaning the tapping line of a beverage dispensing system is disclosed in which 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 container and dispensed similar to a beverage.
  • WO 2010/060946 and WO 2011/117192 both relate to a method of cleaning the tapping line of a beverage dispensing system in which a cleaning and flushing cartridge for external use is described.
  • the cleaning and flushing cartridge is installed outside the pressure chamber and has a pressure fluid source connected.
  • the rinsing and flushing fluid is dispensed similar to a beverage.
  • WO 2010/060949 relates to a beverage dispensing system having a first and a second detector for generating a control pressure.
  • the method comprises evaluating the control pressures from the control pressure outputs of detectors for determining the operational mode of the beverage dispensing system.
  • a method of installing a collapsible beverage container in a beverage distribution unit comprises the steps of positioning the collapsible beverage container in a sloped position, pivoting the collapsible beverage container in a rotational motion around a support surface and sliding the collapsible beverage container on the support surface.
  • a non-return valve may be used in the tapping line.
  • a spring loaded valve may be used in order to prevent dripping.
  • An example of a beverage dispenser including a plurality of valves is DE 296 04 703 U1 , in which an electrical liquor dispensing system is disclosed.
  • the tapping line has a non-return valve and a spring loaded lid. The liquor is propelled from a container through the tapping line by an electrical pump and explicitly not by pressurized gas.
  • a pressure fluid typically a gas
  • the pressure fluid acts on the collapsible beverage container and forces the beverage out of the pressure chamber while simultaneously crumpling the collapsible beverage container.
  • the volume of the crumpled collapsible beverage container is thereby reduced corresponding to the amount of the dispensed beverage.
  • the collapsible beverage container is made of flexible and preferably disposable materials such as thermoplastic materials.
  • the interior of the collapsible beverage container is divided into a beverage space constituting carbonated beverage and initially occupying the majority of the interior of the beverage container and a head space filled with gas, primarily constituting CO 2 gas.
  • the force applied to the beverage container by the pressure in the pressure chamber causes the beverage to flow out of the beverage container and into a tapping line.
  • the tapping line leads to a dispensing device which may be located at a distant location such as one floor above the pressure chamber.
  • the dispensing device typically has 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.
  • a problem often observed when the beverage space of the beverage container is empty or almost empty is that the gas of the head space starts entering the tapping line. Such gas will result in gas bubble formation in the tapping line. The presence of gas bubbles in the tapping line will cause excessive frothing and aeration of the carbonated beverage at the tapping valve of the dispensing device. The carbonated beverage dispensed will thus be very foamy and will have a less than optimal taste and appearance. Typically, this beverage therefore has to be disposed of. This is also an indication for the bar employee to exchange the empty and crumpled collapsible beverage container with a new collapsible beverage container filled with beverage.
  • the total loss of beverage may amount to 2-4 servings for each beverage container, i.e 1-2 at the beginning of each container and 1-2 at the end of each container, resulting in a loss of about 10% of the beverage included in a typical 20 liter collapsible beverage container
  • a modular beverage dispensing system i.e. a system wherein a single tapping line is fed from a multitude of collapsible beverage containers
  • the problem is even larger since the beverage spaces of the different collapsible beverage containers may be empty at different times, resulting in even more beverage lost.
  • the object of the present invention is thus to dispense beverage while preventing that any gas from the head space is entering the tapping line.
  • a method of dispensing carbonated beverage comprising the steps of: providing a beverage dispensing system, the beverage dispensing system comprising a pressure chamber, the pressure chamber accommodating a collapsible beverage container made of a flexible material, the collapsible beverage container including a beverage space consisting of carbonated beverage and a head space consisting of gas, a dispensing device including a tapping valve and defining a beverage dispensing position and a non-beverage dispensing position, a tapping line interconnecting the collapsible beverage container within the pressure chamber and the dispensing device, and an interruption valve defining an open position and a closed position, the open position allowing carbonated beverage to flow from the beverage space to the dispensing device when the pressure chamber is pressurized, the closed position preventing carbonated beverage to flow from the beverage space to the dispensing device, maintaining a first elevated pressure within the
  • the beverage dispensing system may be a non-modular system in which one pressure chamber is connected to one dispensing device via a single tapping line, or a modular system in which a plurality of pressure chambers are selectively connected to one or more dispensing devices via one or more tapping lines.
  • the pressure chamber is typically a pressure proof container connected to a fluid pressure source, typically a high pressure air source.
  • the pressure chamber typically has a pressure lid in order to be able to insert and remove the collapsible beverage container
  • the collapsible beverage container is typically made of a semi rigid metallic or polymeric material having a thickness such that it is capable of retaining its shape during transport and handling but which may collapse and crumple when subjected to an outer pressure.
  • the beverage container may be initially sealed during transport and handling.
  • the beverage space typically occupies about 90% to 95% of the total volume of the beverage container and the head space is occupying the remaining 5%-10%.
  • the tapping line leads from the collapsible beverage container within the pressure chamber to the dispensing device outside the pressure chamber.
  • the dispensing device typically comprise a tapping valve and an tapping handle for the user to be able to selectively dispense or not dispense beverage by switching between the beverage dispensing position in which the tapping valve is open and the non-beverage dispensing position in which the tapping valve is closed.
  • the first elevated pressure to be maintained in the pressure chamber is established after the collapsible beverage container has been installed in the pressure chamber.
  • the first elevated pressure is typically held substantially constant until the collapsible beverage container is to be exchanged at which time the pressure is let out
  • the first elevated pressure acts uniformly on the wall of the collapsible beverage container in order to establish the second elevated pressure inside the collapsible beverage container.
  • the second elevated pressure is thus the pressure within the beverage
  • the first elevated pressure is thus transmitted via the wall of the collapsible beverage container to establish the second elevated pressure.
  • the second elevated pressure will be smaller than the first elevated pressure and that the difference between the first elevated pressure and the second elevated pressure is constituted by the pressure required to crumple the collapsible beverage container, i.e. the crumpling pressure, for overcoming the internal resistance against a change of the shape of the wall.
  • the crumpling pressure is dependent on the level of crumpling of the collapsible beverage container, i.e. a new (full) non-crumpled collapsible beverage container will have a much lower resistance against crumpling than an already crumpled beverage container.
  • crumpling pressure increases during beverage diseasing as the volume of the beverage space and thereby the total volume of the collapsible beverage container is reduced.
  • the increase in crumpling pressure is non-linear for most materials and most collapsible beverage containers will exhibit an exponential increase in the required crumpling pressure when the beverage space of the beverage container is almost empty. This effect may be explained by the fact that the first few beverage dispensing operations of a new collapsible beverage container will result in an elastic deformation of the wall of the collapsible beverage container. Such elastic deformation is linear of nature.
  • the deformation of the wall of the collapsible beverage container will exhibit a plastic deformation, which is non-linear and requires a significantly higher crumpling pressure.
  • the second elevated pressure will reduce.
  • the crumpling characteristic of a typical collapsible beverage container will be at least somewhat stochastic, i.e. two seemingly identical collapsible beverage containers may crumple slightly different depending on the internal wall structure of each collapsible beverage container.
  • the above fact may be utilized by employing an interruption valve.
  • the interruption valve is preferably situated in the tapping line adjacent the beverage container.
  • the interruption valve will be open and allow beverage to pass when the dispensing device assumes the beverage dispensing position. Later, when the collapsible beverage container is almost empty and thus seriously crumpled, the crumpling pressure will have increased and provided the first elevated pressure is held substantially constant, the second elevated pressure will be much smaller.
  • the interruption valve will be closed and beverage will not be allowed to pass even when the dispensing device assumes the beverage dispensing position. This will allow a very well defined end of the beverage dispensing operations when the collapsible beverage container is empty or nearly empty
  • the non-zero pressure reference is chosen such that the beverage dispensing is interrupted well before the beverage space is empty such that there is no risk that gas from the head space will enter the tapping line
  • the specific non-zero pressure reference may thus not be zero, since this would mean that the container crumpling pressure is equal to the first pressure, which first pressure is typically sufficient to completely flatten the collapsible beverage container
  • the beverage dispensing will be very slow due to the lack of driving pressure and such situations should also be avoided.
  • the interruption valve will always be closed and beverage dispensing never allowed.
  • the interruption valve may be closed when the second elevated pressure is still high enough for dispensing and the beverage space still includes a small amount of beverage. In this way, no gas will be introduced into the tapping line.
  • the tapping line will be free from gas and the first servings of carbonated beverage will not suffer from any excessive foaming.
  • the only lost beverage will be the small amount remaining in the crumpled beverage container, however, this amount will be much smaller than the amount of carbonated beverage lost due to excessive foaming.
  • the interruption valve is located in the collapsible beverage container, the tapping line or the dispensing device.
  • the interruption valve is located in the collapsible beverage container In this way there is no need for any modifications of the permanent parts of the beverage dispensing system.
  • the interruption valve may be used for sealing the beverage container during transport and handling, thereby omitting the need for a separate seal.
  • the interruption valve may be provided as a re-usable accessory which is mounted on the collapsible beverage container
  • the interruption valve is preferably fixedly mounted in the tapping line adjacent the collapsible beverage container.
  • the pressure in the tapping line may be considered to be equal to the pressure within the collapsible beverage container, at least at a location adjacent the collapsible beverage container. However, in case the tapping line leads to another floor of a building, it is contemplated that the pressure will fall.
  • the interruption valve is located in the dispensing device. In this way, a visual indication may be given that the beverage container is empty. In this embodiment, a non-return valve may be used adjacent the beverage container to avoid a return flow of beverage. Further, the pressure may be slightly lower at the interruption valve than inside the collapsible beverage container depending on the height difference between the collapsible beverage container and the dispensing device.
  • the interruption valve employs a loaded spring or a sealed pressurized gas volume in order to establish the specific non-zero pressure reference
  • the interruption valve changes from the open position to the closed position.
  • the specific non-zero pressure reference may be established by a loaded spring having a suitable spring constant and pre-load such that the valve remains open when the second elevated pressure is higher than the specific non-zero pressure reference but closes rapidly when the second elevated pressure falls below the specific non-zero pressure reference
  • a sealed pressurized gas volume may substitute the spring.
  • the interruption valve is fluidly connected to the first elevated pressure of the pressure chamber via a pressure regulator for establishing the specific non-zero pressure reference.
  • a pressure regulator acting as a pressure reduction valve.
  • the non-zero pressure reference may be made dependent on the first elevated pressure, i.e. the pressure in the pressure chamber.
  • the first elevated pressure may be increased while still allowing the interruption valve to be closed when the collapsible beverage container has been crumpled to such extent that only a very small amount of beverage remains.
  • the interruption valve includes a pressure probe for determining the second elevated pressure and an electromagnetic valve for assuming the open and closed positions, respectively, dependent on the second elevated pressure.
  • the pressure probe may be mounted in the tapping line in order to constantly monitor the second elevated pressure. As soon as the second elevated pressure falls below the specific non-zero pressure reference, an electrical signal may be sent to the electromagnetic valve in order for the interruption valve to close. It is contemplated that a control unit may be used to compensate the specific non-zero pressure reference in order to take account of any changes in the first elevated pressure.
  • the first elevated pressure is in the range of 2-5 bar above atmospheric pressure, preferably 3-4 bar above atmospheric pressure
  • Such pressures are suitable for achieving a good driving pressure for the beverage which will overcome the crumpling pressure of the collapsible beverage and still allow beverage to be dispensed at a reasonable velocity at a higher location than the location of the beverage container.
  • the second elevated pressure is in the range of 1-4 bar above atmospheric pressure, preferably 2-3 bar above atmospheric pressure.
  • the second elevated pressure must still allow beverage to be dispensed at a reasonable velocity at a higher location than the location of the beverage container.
  • the beverage container is positioned in an upside down orientation within the pressure space such that the beverage space is located adjacent the tapping line and the head space is located spaced apart from the tapping line.
  • upside down position is meant a position in which the outlet of the beverage container is directed downwardly. In this way, the beverage space will be located adjacent the outlet and the head space will be located as far as possible from the outlet and consequently the head space will not reach the outlet until the beverage space is depleted This will also completely avoid the use of a ascension pipe.
  • specific non-zero pressure reference is in the range of 0.1-3 bar, preferably 0.5-1 bar, absolute pressure. For most cases such pressure values will be suitable in order to achieve a well defined end of beverage dispensing when the collapsible beverage container is empty or almost empty
  • the crumpling pressure being dependent on the level of crumpling of the collapsible beverage container, the crumpling pressure being in the range of 0-1 bar absolute pressure when the beverage container is in an initial non-crumpled state whereas the crumpling pressure is in the range of 2-5 bar when the beverage container is in a crumpled state in which the volume of the beverage container is reduced to 5% of the volume of the beverage container in the initial non-crumpled state.
  • the crumpling pressure being dependent on the level of crumpling, i.e. the more crumpled the beverage container is, the higher pressure is required in order to further crumple the beverage container.
  • the crumple pressure will be very low, or even zero, since the deformation will be elastic and thereby have a linear relationship with the applied force.
  • the applied force is very high and additional deformation will require even higher force since the deformation may be permanent, i.e. a plastic deformation
  • the crumpling pressure thus typically is exponentially dependent on the dispensed volume of beverage
  • the collapsible beverage container is typically made using such material, volume and wall thickness such that when only 5% of the volume remains, i.e. the crumpling pressure is in the range of 2-5 bar.
  • the beverage space when the interruption valve assuming the closed position, has a volume of between 1 and 100 ml, preferably between 10 and 50 ml, such as 40 ml.
  • a volume of between 1 and 100 ml preferably between 10 and 50 ml, such as 40 ml.
  • at least a tiny amount of beverage should remain in the beverage container when the interruption valve assumes the closed position.
  • too much beverage remaining in the beverage container would constitute a waste since such beverage will not be dispensed
  • the collapsible beverage container is made of the flexible material constituting a thermoplastic material such as PET.
  • PET is a suitable material since it is sufficiently flexible to be crumpled, it is suitable for food and beverage and it may be disposed of in an environmentally friendly way, e.g. by combustion or recycling.
