Patent Application
20230137701
The present invention relates to a beverage preparation device, which can be integrated for example in a stand-alone drink dispensing or vending machine. The present invention may be used to prepare a wide spectrum of beverages. Such beverages are usually composed of water and at least one beverage additive like flavor or aroma, etc.
In order to prepare and dispense such beverages, some of the known beverage preparation devices may comprise a beverage preparation section, a water supply, and an additive supply for supplying beverage additive(s) to be mixed with water from the water supply in the beverage preparation section.
However, the present applicant has observed that the known beverage preparation devices present the following problems and drawbacks. The additive supply must usually contain preservatives to prevent the beverage additive(s) from decaying and thus keep the beverage additive(s) safe and tasty all along their storage in the beverage preparation device.
It can nevertheless be desirable to prepare beverages with beverage additive(s) having little or no preservatives. But such beverage additive(s) have too short a shelf-life to be used in the known beverage preparation devices, as such beverage additive(s) would require too frequent replacements, typically every 3 or 4 days, and thus risk producing much waste.
In view of the above-mentioned problems and drawbacks, the present invention aims to improve the current implementations. An objective is to provide a beverage preparation device that may prepare beverages with beverage additive(s) having little or no preservatives. The objective is achieved by the subject-matter defined in the independent claims. Advantageous implementations are further defined in the dependent claims.
An embodiment of the invention provides a beverage preparation device comprising:
Thus, the cooling device makes it possible to extend the shelf-life of the beverage additive to e.g. a few weeks by maintaining a low and constant temperature in the beverage additive. So the beverage preparation device may be loaded with containers carrying beverage additive(s) having little or no preservatives. With the present invention a ready-to-drink beverage may be prepared in a safe and hygienic manner.
Besides, the energy consumption of the cooling device can be small since the cooling device is part of the additive supply, which has the storage section housing the containers.
In some implementations, the water supply may be fluidly connected to a water distribution network (tap water). Alternatively, the water supply may be fluidly connected to a water container located in or near the beverage preparation device containing for example, spring water, mineral water or drinking water.
In the proposed implementations, the water can be supplied as still water or carbonated water (sparkling water), preferably with a choice of different carbonation levels.
The water may also be dispensed at different temperature according to the user selection. The water may be selected cool, at room temperature or heated.
In various implementations, the cooling device may be a refrigerator encasing the storage section.
Thus, the refrigerator may cool down the storage section, hence also the containers stored therein and the beverage additives contained in these containers. As the refrigerator dimensions may be adapted to the storage section, the energy consumption of the refrigerator can be minimized, i.e. set to the minimum necessary to cool down the beverage additives.
In some implementations, the refrigerator may have a parallelepiped shape.
In a possible complementary implementation, the piping and pumps associated with the supply of the beverage additive(s) to the beverage preparation section may also be located within the refrigerator.
In various implementations, the cooling device may comprise a door for accessing the storage section and in particular the containers stored therein.
Thus, the door may enable an operator to quickly unload and load, hence replace, the containers stored in the storing section of the cooling device.
In various implementations, the cooling device may comprise spacers, preferably insulated, like ridges, to support the containers within the storage section distant from a cold portion of the cooling device.
Thus, the spacers may prevent a beverage additive from freezing since the spacers keep the containers distant from the cold portion, for example an inner wall of a refrigerator, which would be at a temperature below 0° C.
Preferably, the spacers may be made of insulating material.
In various implementations, the beverage preparation device may further comprise a heat dissipating element for dissipating heat out of the cooling device, wherein the heat dissipating element comprises a ventilation device and/or a heat conduction structure like a heat sink.
Thus, the heat dissipating element may help the cooling device efficiently cool down the storing section and/or controlling the temperature inside the beverage preparation device.
In various implementations, the additive supply may further comprise an additional storage section for storing additional containers respectively carrying an additional beverage additive at ambient temperature.
Thus, the additional storage section makes it possible for the beverage preparation device to add ingredients in the prepared beverage beside the beverage additives.
In various implementations, the containers and, if any, the additional containers may be bag-in-boxes.
Thus, the bag-in-boxes may enable an operator to conveniently and quickly unload and load the containers, while preserving their content.
Alternatively, the containers may be a packaging of the Tetra Pak© type or equivalent. Alternatively, the containers may be made of any kind of material, structure and shape compatible with the intended use.
In various implementations, at least one beverage additive carried by the containers in the storage section may be selected in the group consisting of flavors, aromas, minerals, mineral solution, mineral liquid concentrate, oligo elements vitamins, vitamins premix, coffee extract for example caffeine, tea extract, plant or vegetable extract or component, fruit juice, fibers, probiotics, prebiotics, prophylactics ingredients, and preferably said at least one beverage additive may have less than 0.03% of preservatives, more preferably no preservative.
Thus, the beverage additive may be a flavor or an aroma, preferably natural and preferably without colorant, for example orange, peach, lemon, etc. or a mix of flavor or aroma, for example, pineapple-ginger, mint-cucumber, etc. The beverage additive may be a tea extract or a coffee extract, a fruit juice or extract, a mineral solution, a mineral liquid concentrate or a premix of minerals, or any so-called “functional concentrate” or “functional enhancer”, which produces an effect on the consumer, in particular an effect different from an organoleptic effect. For example, the beverage additive may be a probiotic, a prophylactic, a vitamin, proteins, fibers, caffeine or another coffee or tea extract.
Preferably, the beverage additive may be in the form of concentrated solutions.
In a complementary implementation, the beverage additive may be a premix of one or more beverage additive, for example a mix of flavor or a mix of minerals.
Preferably, at least one of the beverage additives carried by the containers may have less than 0.03% preservatives. More preferably, at least one of the beverage additives carried by the containers contains no preservative.
In various implementations, the storage section may be designed to receive the containers in a tilted orientation to facilitate dispensing of the beverage additives respectively carried by the containers, and preferably the additional storage section may also be designed to receive the additional containers in a tilted orientation to facilitate dispensing of the additional beverage additives respectively carried by the additional containers.
More particularly, the container tilting orientation shall be directed to have the connection device at the lowest point of the container to facilitate dispensing and allow the container to be emptied with no remaining product inside.
Thus, most or all of the beverage additives or of the additional beverage additives may be dispensed in the prepared beverages, which reduces waste. The tilted orientation of the containers and the tilted orientation of the additional containers is measurable with respect to a horizontal direction when the beverage preparation device is in service on a horizontal surface.
In various implementations, the cooling device, preferably the refrigerator, may be tilted and/or wherein the storage section may have a sloped part for carrying the containers in an inclined manner, the sloped part being preferably an inner bottom wall of the cooling device and/or the spacers.
Thus, most or all of the beverage additives or of the additional beverage additives may be dispensed in the prepared beverages, which reduces waste. The tilted orientation of the cooling device and/or of the sloped part is measurable with respect to a horizontal direction when the beverage preparation device is in service on a horizontal surface.
In various implementations, the water supply and the beverage preparation section may be fluidly connected by at least one water duct, and the additive supply and the beverage preparation section may be fluidly connected by at least one additive duct, the at least one additive duct being preferably thermally insulated and/or cooled down.
Thus, the thermal insulation of the at least one additive duct may minimize the energy consumption required to preserve the beverage additives by keeping those at low temperature.
In various embodiments, the water duct may comprise at least one pipe, tube, hose or channel. In various embodiments, the additive duct may comprise at least one pipe, tube, hose or channel.
In various embodiments, the additive supply may comprise at least one additive pump configured for supplying additive, preferably in a fluidic state, from a container to the beverage preparation section. In various embodiments, the additive pump may be a peristaltic pump configured to compress a respective additive duct.
In various implementations, the water supply may comprise a water cooling section for cooling water to be delivered to the beverage preparation section, the water cooling section may be a separate chiller or is part of the cooling device, the water cooling section preferably comprising a cooling loop being guided through the cooling device.
Thus, when the water cooling section is a separate chiller, the water cooling section may be cooled at a different temperature vis-à-vis the cooling device which cools the beverage additives. Besides, when the water cooling section is part of the cooling device, the required space and cost for the cooling components may be kept low and in particular minimized.
In various implementations, the beverage preparation section may comprise a mixing chamber for preparing a beverage by mixing the water supplied by the water supply and, if any, a beverage additive supplied by the additive supply, and/or, if any, an additional beverage additive supplied by the additive supply, and/or the beverage preparation section may comprise a dispensing outlet for dispensing the beverage product, preferably out of the mixing chamber.
Thus, the mixing chamber may mix the beverage components, for example water and beverage additives, before dispensing the beverage. Besides, the dispensing outlet may dispense the prepared beverage in a user's cup or glass.
In various implementations, the beverage preparation device may further comprise a control unit for controlling a beverage preparation, preferably upon a user's selection, and/or for controlling a temperature of the cooling device and/or of a container to be cooled, and/or and a sensor may be configured to detect a temperature in the cooling device and/or a temperature of a container to be cooled, wherein the control unit may preferably be configured to prevent or stop the beverage preparation with the beverage additives if the detected temperature is equal to or exceeds a threshold value, preferably until the temperature drops below the threshold value and/or said container is replaced.
Thus, the control unit may control the operation of the beverage preparation device and in particular the composition of a beverage to be prepared in accordance with a user's selection. Besides, the sensor may avoid preparing a beverage with beverage additives that have not been suitably preserved.
In various embodiments, the threshold value may be 20 to 25° C. during a period of more than 4 to 6 consecutive hours
In various embodiments, even when the control unit prevents the beverage preparation with the unpreserved additives, the beverage preparation device may continue to dispense water or beverages prepared with the additional additives, which are not cooled by the cooling device.
In various implementations, the Beverage preparation device may further comprise a housing for housing the beverage preparation section, the water supply, and the additive supply.
Thus, the housing may compose a stand-alone drink dispensing machine, for example a stand-alone drink vending machine.
