A beverage unit with a liquid flow path has a liquid inlet at one end in fluid communication with the base liquid in the base liquid source and a beverage outlet at an opposite end. An ingredient container receiving means has an ingredient container installed so the contents are in fluid communication with the liquid flow path for mixing the contents with a base liquid in the liquid flow path. A gas pressure regulation unit has a pressure chamber in the liquid flow path downstream of the communication between the liquid flow path and the ingredient container contents. A gas ingredient inlet is in fluid communication with the pressure chamber.

Description

  • The present invention relates to a beverage dispensing device for dispensing different types of beverages or beverage components, wherein at least one of the beverage ingredients is provided for mixing the ingredient with a base liquid.
  • More in particular, the present invention relates to such a beverage dispensing device, wherein at least one of said beverages or beverage components is a malt based beverage or a malt based beverage component.
  • At present there is a trend to fancier kinds of beverages, wherein multiple beverage components or beverages are added to one another so to provide a consumer with a sensation adapted to his taste.
  • According to the state of the art all kinds of beverage dispensing devices exist which allow for the dispensing of different types of beverages or beverage components, such as beverage dispensing devices for dispensing different types of coffees and teas possibly mixed with milk, cream or sugar and so on.
  • Usually, the coffee or tea is made by passing hot water through coffee powder or tea leaves respectively.
  • Other beverage dispensing devices are for example intended for dispensing all kinds of juices or sodas.
  • It is clear that such beverage dispensing devices are of a complete other category than the type of beverage dispensing devices of interest in the present invention.
  • Indeed, the dispensing of different types of beverages or beverage components wherein at least one of the one of said beverages or beverage components is a malt based beverage or a malt based beverage component or a cider requires adapted equipment which is capable of coping with the specific needs related to malt based beverages or beverage components.
  • For example when dispensing a malt based beverage or beverage component, it is important to control foaming of the concerned beverage or beverage component.
  • Furthermore, the rate of dispensing, the pressures involved during dispensing and the volumes of liquid dispensed in beverage dispensing devices wherein at least one of the beverages or beverage components is a malt based beverage or a malt based beverage component are usually much higher than in the typical coffee machines or the like and require adapted equipment with increased capacity and strength.
  • Moreover gas pressure in the beverage is considered a key component for the refreshing sensation and taste of malt-based beverages or ciders and needs to be kept within a narrow range (in function of temperature and beverage type) to meet the consumers expectations, without increasing dispensing time or beverage preparation time.
  • It is understood that dispensing of such a beverage requires some skill and is time consuming.
  • It is also clear that depending on the person that is dispensing the beverage the volume ratio of the different beverage components dispensed can vary easily, resulting in a varying composition of the finally dispensed beverage, which is often not desired.
  • It is therefore an objective of this invention to overcome one or more of the above-mentioned drawbacks or possibly other non-mentioned drawbacks of the known beverage dispensing devices.
  • To this aim, the present invention proposes a beverage dispensing assembly for preparing and dispensing a carbonated beverage the assembly comprising:
      • a source of pressurized base liquid having CO2, N2 or N2O dissolved therein and having a gas pressure of at least 0.5 bar overpressure at 2° C.;
      • a beverage unit with a liquid flow path having a liquid inlet at one end, in fluid communication with the base liquid in the source of base liquid by means of a valve and a beverage outlet at an opposite end; an ingredient container receiving means having an ingredient container installed therein such that when correctly installed, the content of the ingredient container is in fluid communication with the liquid flow path for mixing the content of the ingredient container with a base liquid in the liquid flow path;
      • a gas pressure regulation unit having a pressure chamber provided in the liquid flow path downstream of the fluid communication between the liquid flow path and the content of the ingredient container; a gas ingredient inlet in fluid communication with the pressure chamber through a valve.
  • The dispensing device further preferably comprises a device for measuring the amount of dissolved and/or entrained gasses in the beverage, said measuring device configured to measure the amount of dissolved and/or entrained gasses in the beverage at a location along the liquid flow line downstream of the fluid communication between the ingredient container content and the liquid line, and upstream the gas pressure regulation unit.
  • A microprocessor and actuator configured to control operation of the valve provided at the gas ingredient inlet in the gas pressure regulation unit based on input received from the measuring device is preferably provided allowing regulating the gas pressure of the beverage to a desired level.
  • The gas ingredient inlet can be coupled to a pressurized gas source or to a source of food-grade carbonates or acids capable of generating carbon dioxide when reacted in the presence of water.
  • The present invention also concerns a method for preparing dispensing a carbonated beverage comprising the steps of:
      • providing an ingredient container;
      • providing a pressurised base liquid having an CO2, N2 or N2O dissolved therein and having a gas pressure of at least 0.5 bar overpressure at 2° C.;
      • mixing the content of the ingredient container with the base liquid to prepare the beverage to be dispensed;
      • subsequent to the mixing step, increasing the gas pressure of the beverage prior dispensing by mixing the beverage and an amount of a gas ingredient;
      • dispensing the beverage.
  • The ingredient container preferably contains a unit dose of beverage ingredient intended for preparing one single beverage.
  • According to a preferred execution the method comprises the additional step of measuring the gas pressure on the beverage after the step of mixing the content of the ingredient with the base liquid and before the step of increasing the gas pressure of the beverage.
  • The increasing of the gas pressure in the beverage (further also addressed as recarbonation) is obtained by contacting the beverage with a pressurized gas stream comprising CO2, N2 or N2O and optionally a scent.
  • With the intention of better showing the characteristics of the invention, hereafter, as example without any limitative character, some embodiments of a beverage dispensing device according to the invention are described, with reference to the accompanying drawings, wherein:

  • It has been observed that upon mixing with at least some ingredients, gas pressure on the beverage (base liquid+mixed ingredient(s)) reduces due to gas scavenging properties of the ingredient.
  • Such gas pressure drop has an important influence on the perceived taste and freshness sensation of a consumer consuming the beverage, especially in case of beer or cider. Therefore, the assembly comprises a gas pressure regulation unit, wherein the mixed beverage is contacted with CO2, N2 or N2O increasing the gas level in the beverage and compensating for the gas loss occurred during mixing.
  • In order to fine tune control of the gas pressure regulation or increasing the gas pressure it is preferred that the gas level or level of CO2, N2 or N2O dissolved in the beverage is measured post mixing. The outcome of this measurement is used for determining the gas pressure increase to be realised during the gas pressure regulation step that hence can be amended in terms of duration, amount of CO2, N2 or N2O fed and/or pressure of the CO2, N2 or N2O fed.
  • Methods for increasing the gas pressure in a liquid are well-known in the art and it is within the reach of a person skilled in the art to determine the specifics and settings of the gas pressure increase based on the gas increase to be realised.
  • As, according to the invention, the base liquid is carbonated prior mixing, a limited gas pressure regulation step will be needed only increasing the gas pressure level in small amounts, allowing performing this step in a rather quick manner not unduly increasing the dispense time for the beverage.
