Definitions

  • Hot drinks Installations for preparing hot drinks are known per se in numer ⁇ ous variants. It is, of course, known that a hot drink can be prepared from a cold drink by placing the drink in a container suitable for this purpose (such as, for example, a pan or something similar) and heating said container.
  • a container suitable for this purpose such as, for example, a pan or something similar
  • a number of products, such as chocolate milk, coffee and the like are found to undergo a change during a heating process carried out in such a way, as a result of which the taste is adversely affected and clearly impaired as far as the consumer is concerned.
  • attempts have already been made to solve this problem in various ways.
  • a liquid concentrate for example, use is made of a liquid concentrate, a metered quantity of which is fed, together with a metered quantity of hot water, to a mixing unit, in which a mixture of the desired composition and at the desired temperature, suitable for immediate consumption, is prepared, which mixture is then dispensed into a cup, beaker or something similar.
  • the use of concentrate has a number of disadvantages, in particular lying in the fact that the concentrates have to be prepared via a separate process, the desired drink generally being first prepared and a liquid or pulverulent concentrate then being prepared from said desired drink.
  • the aim of the invention is, now, to eliminate these additional steps for the preparation of a concentrate by providing an installation with which a hot drink can be prepared in a simple manner starting from the prepared cold drink, without this resulting in the abovementioned taste disadvantages.
  • the invention provides an installation for preparing a drink, comprising: a reservoir in which the drink is present at a temperature which is lower than the desired temperature, a metering unit, coupled to the reservoir, for measuring a pre- determined quantity of drink, heating means, connected to the metering unit, through which the measured quantity of drink flows and, during this operation, is brought to the desired temperature, and a control unit which controls the metering unit and the heating means in such a way that the measured quantity of drink is dis ⁇ claimedd at the desired temperature at the outlet of the heating unit.
  • the heating unit is provided with - a steam generator, steam metering means and a mixing chamber which is connected both to the drink metering means and to the steam metering means, the quantities of drink and steam fed by said metering means to the mixing chamber being mixed in the mixing chamber.
  • the reservoir is formed by a container of flexible material which contains drink at least virtually exclusively, which container is supported by a casing of non-flexible material.
  • a reservoir of this type which is also known under the English term of bag-in-box, is already known per se for the storage of drinks or drink concentrates, for example from Japanese Patent Publication J 6211 299 and from European Patent Application EP 02 2420.
  • the combination of a reservoir of this type with a metering unit and heating means is, however, not indicated in said publications.
  • the reservoir is provided with coupling means by means of which the reservoir can be detachably con ⁇ nected to the metering unit.
  • the reservoir is formed by a container of flexible material which contains drink exclusively, which container is supported by a casing of non-flexible material.
  • the measuring and feeding of a desired quantity of cold drink is effected in that the reservoir is connected to a first connection opening of a three-way tap, the second connection opening of which is connected to the meter ⁇ ing unit and the third connection opening of which is connected to the spray unit in the mixing chamber, wherein in one position of the tap the first connection opening communicates with the second connection opening and in the other position of the tap the second connection opening communicates with the third connection opening.
  • the installation comprises more then one reservoir.
  • One of said embodiments is characterised in that the installation comprises a second reservoir in which a drink is present at a tempera- ture which is lower than the desired temperature, and that the in ⁇ stallation further comprises selection means for selectively connect ⁇ ing either the outflow opening of the first reservoir or the outflow opening of the second reservoir to the metering unit.
  • the in- stallation furthermore comprises an additional reservoir in which a cleaning solution is present, the outflow opening of said further reservoir being connected to said selection means which are embodied such that either drink from a reservoir or cleaning solution from said additional reservoir is passed to the metering unit.
  • the installation comprises a second reservoir in which a drink is present at a tempe ⁇ rature which is lower than the desired temperature, second metering means coupled to the second reservoir for measuring a predetermined quantity of drink, and selection means for selectively connecting either the outflow opening of the first metering unit or the outflow opening of the second metering unit to the heating means.
  • the installation may comprise a unit for dispensing a predetermined quantity of powdered material, such as sugar, and may comprise furthermore an intermediate flow through chamber at the outflow side of the heating means, said intermediate chamber recieving both the heated drink from the the heating means as well as the powdered material from the dispensing unit to mix the drink with the powdered material while they pass the intermediate chamber.

  • Both embodiments of said bag in box are distiguishable from prior art bag in boxes because in stead of a hose most prior art bag in box configurations comprise an outlet valve.
  • Cooling means for cooling the cold drink can optionally be present in or on the reservoir.
  • the dimensions of the reservoir are so chosen that the reservoir as a whole fits inside the installation which will be described in more detail below.
  • the dimensions are furthermore so chosen that the capacity of the reservoir is sufficient to be able to serve a predetermined number of portions of hot drink over a predetermined period.
