Description

COOLING PROCESS AND SYSTEM FOR COFFEE DISPENSED FROM FILTERS OF THE "POUR-OVER/BATCH-BREW" TYPE
The present invention relates to a cooling process and system for coffee dispensed from filters of the "pour-over/batch-brew" type, for example of the V60 type and the like.
In the absence of relevant prior art, the objects of the present invention were:
• developing a process and an extraction technology for espresso coffee that offer superior quality in the cup based on reducing the loss of aroma from extraction to cup;
• providing a rational understanding of the sensory improvement observed, relative to the situation without the new technology. The rationale behind the project revealed that significant losses of volatile substances occur between extraction and when coffee reaches the cup. These observed losses are believed to lead to a reduction in sensory quality in the cup. The aim of the proposed technology is to reduce these losses by improving quality. The research also revealed that the content of aromatic compounds is particularly high in the first 5 ml/g of the extract.
The invention therefore aims to cool the first few ml/g of extract, as soon as it comes out of the coffee panel until it reaches the cup, to reduce the loss due to evaporation and therefore increase the amount of aroma retained in the extract. Therefore, the relevant parameters are:
• temperature of the filter holder/spout and duration of cooling;
• reduction of the complete free distance from the spout to the cup;
• prevention of turbulence when hitting the cup and reducing the free flight trajectory.
Document DE-A1-19 56 536 describes a cooling system for generating cold coffee. Document US-A1- 2007/017381 describes a process for generating cold coffee.
Object of the present invention is solving the aforementioned prior art problems, by providing a cooling process and system for coffee dispensed from "pour-over/batch-brew" filters, for example of the V60 type and the like, which allow condensing the aromas and volatile parts that are generated during the first phase of coffee production, for example coffee dispensed from a filter or other method of extracting coffee or infusions.
A further object of the present invention is providing a process and a system as indicated above which allow coffee coming out of a "pour- over/batch-brew" type filter, for example of the V60 type or the like, at a predetermined temperature, so as to significantly reduce the loss of aromas and volatile substances that normally are dispersed into the environment due to temperature. This procedure significantly enriches the quality of coffee in a cup, increasing the sensory characteristics of the extracted coffee.
The aforementioned and other objects and advantages of the invention, which will emerge from the following description, are achieved with a cooling process and system for coffee dispensed from "pour-over/batch-brew" filters, for example of the V60 type and the like, such as that described in the respective independent claims. Preferred embodiments and non-trivial variants of the present invention form the subject matter of the dependent claims. It is understood that all attached claims form an integral part of the present description.
The present invention will be better described by some preferred embodiments thereof, provided by way of non-limiting example, with reference to the attached drawings, in which:

Figures 3 to 6 are schematic views of a third preferred embodiment of the system according to the present invention; and
- Figures 7 to 10 are schematic views of a fourth preferred embodiment of the system according to the present invention.
With reference to the Figures, preferred embodiments of the present invention are shown and described. It will be immediately obvious that innumerable variations and modifications (for example relating to shape, dimensions, various colors and parts with equivalent functionality) can be made to what is described, without departing from the scope of the invention as appears from the attached claims.
The present invention first of all relates to a cooling process designed for use in systems for producing coffee dispensed from "pour-over/batch- brew" filters, for example V60 type and the like, the process comprising the steps of:
- preparing an amount of ground coffee; proceeding with an infusion (extraction) step by pouring hot water into the ground coffee;
- cooling the brewed coffee before dispensing it, cooling taking place at a temperature between -10 and +10 ° C for a time equal to 25-35% of the total pouring time; and
- brewing coffee without further cooling or at a post-infusion or post-extraction temperature.
In the inventive process, cooling is carried out at the outlet of a "pour-over/batch-brew" type filter, for example of the V60 or similar type for coffee, before coffee is poured into a suitable container 4. This filter is contained in a vessel 3 in which coffee powder is present and into which hot water for infusion/extraction is poured.
With reference to the Figures, the invention also relates to a cooling system designed to carry out the above-mentioned process: this system, in the first embodiment shown in Figure 1, substantially comprises:
- a vessel 3 equipped with at least one filter of the "pour-over/batch-brew" type, for example of the V60 type or the like; a container 4 for the delivered coffee located downstream of the vessel 3 along the coffee delivering direction; and

Alternatively, as shown in Figure 2, this system, in its second embodiment, substantially comprises:
- a vessel 3 equipped with at least one filter of the "pour-over/batch-brew" type, for example of the V60 type or the like; a container 4 for the delivered coffee located downstream of the vessel 3 in the coffee delivering direction; and a cooling device 1 fixedly attached, by means of at least one support arm 2, to the vessel 3.
With reference to Figures 3 to 6, which are schematic views of a third preferred embodiment of the system according to the present invention, this system substantially comprises:
- a vessel 3 equipped with at least one filter of the "pour-over/batch-brew" type, for example of the V60 type or the like; a container 4 for the delivered coffee located downstream of the vessel 3 in the coffee delivering direction;
- a cooling device 1 located downstream of the vessel 3 and upstream of the container 4 so as to come into contact with the coffee dispensed from the vessel 3 before it enters the container 4; and
- a support structure 5 equipped with at least one first support element 7 for the vessel 3 and at least one second support element 8 for the cooling device 1.
In particular, the support structure 5 can also comprise a third support element 9 located downstream of the cooling device 1 and designed to collect any drops of coffee that come out of the vessel 3 at the end of the delivery of coffee itself.
Both the first support element 7, and the second support element 8, and the third support element 9 can be equipped with at least one respective first arm 11, second arm 2 and third arm 12 for the rotating connection to an elongated vertical element 6 with which the support structure 5 is equipped.
Still in particular, both the first support element 7, and the second support element 8, and the third support element 9 can be equipped with at least one respective first fin 7A, second fin 8A, and third fin 9A, all designed to facilitate the rotation of the respective support elements around the elongated vertical element 6, as shown in Figures 3 and 6. As shown better in Figures 4 and 5, however, a respective fourth fin 7B, fifth fin 8B and sixth fin 9B may also be present, mutually coupled with the first fin 7A, the second fin 8A and the third fin 9A, to improve the grip for rotation of the respective support elements.
The system described above also comprises a base 10 on which both the container 4 and the support structure 5 rest by means of its elongated support element 6. This base 10 can be equipped with a temperature sensor described below, and the temperature detected can be conveniently displayed on the base 10 itself, as shown in Figures 3 to 6. With reference to Figures 7 to 10, which are schematic views of a fourth preferred embodiment of the system according to the present invention, this system substantially comprises:
- a vessel 3 equipped with at least one filter of the "pour-over/batch-brew" type, for example of the V60 type or the like; a container 4 for the delivered coffee located downstream of the vessel 3 in the coffee delivering direction;
- a cooling device 1 located downstream of the vessel 3 and upstream of the container 4 so as to come into contact with coffee dispensed from the vessel 3 before it enters the container 4, this cooling device 1 being contained inside a first containment element 15 provided with flared upper edges and designed to prevent sprays of coffee from falling out of the container 4 during coffee dispensing; and
- a support structure 5 equipped with at least one first support element 7 for the vessel 3 and at least one second support element 8 for the cooling device 1.
In particular, the support structure 5 can also comprise a third support element 9 located downstream of the cooling device 1, in turn equipped with a second containment element 16 with flared upper edges, designed to collect any drops of coffee when they come out of the vessel 3 at the end of dispensing coffee. As can be seen from the Figures, the second containment element 16 can be identical to the first containment element 15, or different both in shape and in size (not shown).
Both the first support element 7, and the second support element 8, and the third support element 9 can be equipped with at least one respective first arm 11, second arm 2 and third arm 12 for the rotating connection to an elongated vertical element 6 with which the support structure 5 is equipped.
Still in particular, both the first support element 7, and the second support element 8, and the third support element 9 can be equipped with at least one respective first fin 7A, second fin 8A, and third fin 9A, all designed to facilitate the rotation of the respective support elements around the vertical elongated element 6, as shown in Figures 7 to 10.
In all above-mentioned versions, the cooling device 1 can be made of aluminum, and can be shaped in various solutions (the one shown is a sphere) with different shapes and sizes, but such as to allow a uniform passage of the coffee around it, without splashes and sprays of coffee outside the system of the invention.
The cooling device 1 is brought to the desired cooling temperature through, for example, its storage in a refrigerator, or the use of systems equipped with liquid nitrogen, condensers, Peltier cells or other equivalent solutions.
The system described above can also comprise at least one temperature sensor (not shown), designed to signal the reduction in the temperature of coffee dispensed for the time necessary to enhance the organoleptic qualities of coffee itself.
With the process and system described above, it is possible to cool coffee for a quick time after its extraction/filtration is finished and before it reaches the consumption container.
Some preferred embodiments of the present invention have been shown and described above: obviously, numerous variations and modifications, functionally equivalent to the previous ones, which fall within the scope of the invention as highlighted in the attached claims, will be immediately apparent to those skilled in the art. For example, the cooling device 1 could be placed on the bottom of a filter (for example of the "pour-over/batch-brew" type, for example of the V60 type) or in the middle of the glass or plastic vessel 3.
In the latter case, the idea would be to develop a new "pour-over/batch-brew" type filter, with a cooling device on the bottom, or a container with a filter that incorporates this potentially removable element.
Similar cooling solutions could be used for batch infusion units or the like. Since most volatile aromatic compounds occur in the early part of the post-extraction or post brewing process, the goal of cooling part of the coffee pouring procedure is to keep these aromatic compounds inside the cup in order to optimally improve the aroma of the final coffee produced.
