Definitions

  • the present invention relates to a cooling process and a cooling system for coffee machines.
  • 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. So the relevant parameters are:
  • Object of the present invention is therefore providing a cooling process and a cooling system for coffee machines that allow condensing the aromas and volatile parts that are generated during the first production step of a coffee, for example espresso coffee, or other extraction methods of coffee or infusions.
  • a coffee for example espresso coffee, or other extraction methods of coffee or infusions.
  • a further object of the present invention is providing a process and a system as indicated above which allow cooling for a predetermined time the outlet spout of the filter-holder dispensing unit or of the external accessory placed under them (cooling semi-cones or spheres) at a predetermined temperature, so as to significantly reduce the loss of aromas and volatile substances that are normally dispersed into the environment due to the temperature.
  • This procedure significantly enriches the quality of coffee in a cup, increasing the sensory characteristics of the extracted coffee.
  • FIG. 1 is a schematic perspective view of a first preferred embodiment of the system according to the present invention.
  • Figure 2 is a side view of Figure 1;
  • FIG. 3 is a schematic perspective view of a second preferred embodiment of the system according to the present invention.
  • Figure 4 is a side view of Figure 3.
  • Figure 5 is a schematic view of an embodiment of the chilling part of the system of the present invention.
  • the present invention first of all relates to a cooling process designed for use in coffee machines (not shown, for example espresso or filter coffee machines, or machines for other types of coffee), the process comprising the steps of:
  • the cooling takes place at a temperature between -10 and +10 °C for a time equal to 25-35% of the total pouring time. After that, the coffee temperature, without further cooling, can return to the post-infusion or post extraction temperature.
  • cooling is carried out on the pouring spouts 8 of a dispensing unit 4, 2' of coffee with which the coffee machine is equipped.
  • the invention also relates to a cooling system designed to carry out the above described process, and for use on coffee machines, comprising in a known way a dispensing unit 4, 2' equipped with pouring spouts
  • the inventive system also comprises means 1, 2,
  • the cooling means consist of a cooling unit 1 from which at least one displacement lever 2 projects, equipped with cooling semi-cones or spheres 3 through which coffee passes after passing through the pouring spouts 8 and before being poured into consumable containers 5 (for example common coffee cups), placed on a support 6 protruding from the front surface 7 of the coffee machine.
  • consumable containers 5 for example common coffee cups
  • the cooling means consist of a mobile refrigerating unit 1' adapted to assume a rest position and an operative position, in which it operatively engages the pouring spouts 8 to cool coffee passing through them before being poured into consumable containers 3' (for example, always the common coffee cups) placed on a support surface 4' protruding from the front surface 5' of the coffee machine.
  • the system described above also comprises at least one temperature sensor (not illustrated), designed to allow the temperature of dispensed coffee to be reduced for the time necessary to enhance the organoleptic qualities of coffee itself.
  • the process for reducing the temperature of the filter-holder spout 8 of the spheres/half-comes 3 under the delivering spout 8 can occur through three cooling apparatuses (through conduction, convection or irradiation) that are installed inside the espresso coffee machine, with external tools which enable the system to be used with a common current outlet:
  • the first cooling apparatus employs the technology of temperature abating devices which use an electric compressor with a serpentine containing refrigerating gas, which freezes the part in contact with coffee, taking the components down to a temperature of around -10 °C;
  • the second cooling apparatus adopts the principle of the Peltier cells, which, through an electronic control, can keep the temperature of the delivering spouts 8 around -10 °C, using the mobile refrigerating unit which, through the contact of the abutment walls, performs a transmission of cold, as shown in Figure 4;
  • FIG. 3 Another cooling apparatus to obtain the same purpose is creating a filter-holder with removable spouts 8 enclosed inside a refrigerated box 20 ( Figure 5), which, through the process with Peltier cells or another similar application (conduction, convection, irradiation) can be brought to a negative temperature capable of condensate aromas and volatile parts that are generated during the first extraction step of an espresso coffee.
  • This system with independent electric supply allows using the chilling compound technology also with common coffee machines: this allows using dedicated filter-holders as regards sizes and shape, capable of being adapted to all professional coffee machines.
  • cooling of coffee could also be obtained with an oscillating cooling element made of stainless steel placed under the spouts (instead of around them), or the cooling element could be placed on the bottom of a filter (for example of the V60 type) or in the middle of the glass or plastic dispenser of the filter.
