In particular, when the basket (filter) 23 is disposed in the container 12, the walls of the plates 27 cooperate with the wall (flat surface) 52 of the basket 23 of the filter so as to create the walls of a chamber 54 ''. Steam injected through the nozzles of in ection 30 is broken by ^¬ ies walls (plates 27 and flat surface 52) of the chamber 54 '' and then passes through the baffles, which favorably reduces noise. In the previous embodiments, the axis of the steam jet at the outlet of the injection nozzle 30 is away from the windows allowing the penetration of the jet into the water to break on the wall of the chambers 54, 54 ', 54' ^* .

According to another embodiment of the apparatus 1, the latter comprises a ring 36 disposed in the base 2. In particular, this ring. 36 is installed inside the tank 10 (see Figure 2). In FIG. 10, it can be seen that the ring 36 has a cylindrical body 37, substantially cylindrical in this case, which comprises a lower portion 38 and an upper portion 39. The lower portion 38 and the upper portion 39 are separated by a plate 40 in which a passage 41 is provided, the lower portion 38 surrounds the heating body 11 to limit the amount of liquid (here water) in direct contact with the heating body 11 thus forming a column of water around that -this. The passage 41 allows the steam to flow from the reservoir to the container 12. The upper portion 39 surrounds a portion of the bottom of the container 12, This portion 39 forms a ring limiting the rise of water to the injection nozzles 30 when of enlightenment. To complete the solution limiting the upwelling, the -portion upper 39 also has a border 42 which forms a local connection between said border e the bottom 17 of the. container 12.

According to the present embodiments of the apparatus, the container 12 has an exchange surface 43 (FIG. 9) intended to receive the steam coming off the reservoir 10 and condensations thereof, More precisely _f this exchange surface 43 is bordered by a seal 44 which is formed between the bottom 17 of the container 12 and an intermediate portion 45 of the wall 14 of the tank 10 In particular, the bottom 17 of the container 12 also comprises a flange 46 of substantially annular section directed towards the reservoir 10. This rim 46 is partly in abutment on the seal 44 and on the intermediate portion 45 of the reservoir 10. The exchange surface 43 may also be bordered by the edge 42 of the ring 36. This exchange surface 43 is arranged on the outer portion of the bottom 17 of the container 12, the periphery of this exchange surface 43 is defined, for example, at least substantially in a vertical extension of the side walls 14 of the reservoir 12 and / or the ring 36 or in the immediate vicinity of this extension. That is to say, by extending the walls of the reservoir 12 and / or the crown 3δ upwards, in a position of use of the apparatus 1 placed on a flat (horizontal) support for example, the bottom 17 of the container 12 also comprises a tab 49 resting on a surface 50 provided between a portion of the wall 4 of the reservoir and the intermediate portion 45 of the wall 4. of the reservoir 10 so that the container 12 is stably disposed in one base 2. The lug 49 of the container 12 may comprise a notch 51 intended to engage with a pin (not shown) that comprises the inner surface of the wall 4 of the tank 10 to fix the position of the container 12 in the reserve 10,

The concentrate in the interior of the container 12 can be kept warm in the apparatus 1.

The invention also relates to a method for steam heating a mixture comprising a first liquid and ingredients. According to this heating method, the appliance 1 is connected and / or switched on by the switch 63. The container assembly 12 and the lid 60 is removed from the base 2 of the appliance 1, a second liquid in the tank 10 of the base 2 with a volume of between 50 ml and 150 ml to produce steam. The container 12 is put back in place on the base 2 so that the container 12 is in communication with the reservoir 10, the latter being placed below the container 12. When the container 12 is put back in place, the rim 46 of the bottom 17 of the container 12 rests on the sealing anointed ^f 44 and compresses it against the edge of the intermediate portion 45 that forms the wall 14 of the container 10 thus ensuring a seal between the container 12 and the reservoir 10 (see figure 9).

The container 12 is then filled with whole or pieces of plant ingredients among plants (leaves, roots, etc.), fruits and vegetables. Then, the first liquid, for example water, is poured into the container 12 so as to immerse the ingredients in a predetermined volume of liquid which is between 150 and 250 ml. The extracts of ingredients are not reduced to powder such as a cocoa powder, for example. The volume of predetermined liquid is a function of the concentrate that one wants to achieve. Then, steam is produced in the tank 10 by the boiling water and supplied to the container 12 to the ingredients. The mixture of liquid and vegetable ingredients contained in the container 12 is then stirred (rotated), heated by means of steam that is injected therein, the steam is thus brought to the ingredients until the container 12 a liquid concentrate comprising extracts of said ingredients. The concentration of trarts of ingredients is greater than that of the liquid which has been filled the container 12. The extraction or infusion is carried out, for example, for a period of between two and ten minutes depending on the ingredients used. his .

The assembly formed by the container 12 and the lid

60 can then be easily removed again for pouring the liquid concentrate into a suitable container and a new cycle.

The invention further relates to a method of operating an apparatus for the preparation of a concentrate as described above. According to this method after a few moments of heating the apparatus I, water vapor is. produced by means of the heating body 11 which heats the liquid poured into the tank 12. The steam rises in pressure in the tank 10. When the pressure is sufficient (approximately 5.75 mbar), this creates the opening of the lips 34, 34 'of the first end 32 of the nozzle 30. The vapor can thus flow from the tank 10 to the container 12 via the injection nozzles 30. Steam is thus injected with a jet into the liquid poured into the container 12 and with a flow rate of between 2 ml / min and 40 ml / min. This jet of steam is broken in the liquid by means of jet baffles 22 that includes the apparatus 1.

When the reserve of liquid (water) in the reservoir 10 is exhausted or when the timer 62 triggers X 'stop heating, or that the device 1 is disconnected, the pressure in the tank 10 drops and the lips 34, 34' the first end 32 of the nozzles 30 close, thus preventing the liquid concentrate contained in the container 12 from flowing towards the reservoir 10.

,, Of course the invention is not limited to the embodiments described above and can be applied thereto variety antes d ^f execution.

In the embodiments described, the container. 12 is disposed above the tank 10 and surrounded by the walls 4 of the body 3 of the apparatus 1. The container 12 can be arranged above the walls 4 of the body 3 and the tank 10.
