Description

TECHNICAL AREA

The present invention relates to a device for brewing coffee and a method for brewing coffee.

STATE OF THE ART

Devices for brewing coffee are known in a variety of constructions. So there are so-called espresso machines, in which hot water at high pressure by coffee powder and a filter arranged downstream thereof is pressed through.

On the other hand, there are filter machines in which the coffee powder is disposed on one side of the filter, hot water in the form of brewing water is supplied from this side, so that the brewing water initially passes through the coffee arranged on the filter, typically under the influence of the gravitational force, and thereby extracts the corresponding substances, then passes through the filter and is discharged as a so-called filter coffee.

Among other things problematic in connection with such filter machines, but also in the context of espresso machines, on the one hand the fact that the brewing water runs through the coffee powder relatively slowly, and that this process is slower, the more moistened and extracted the coffee powder is. Furthermore, it is problematic on such machines that either new filters must be provided for each brewing process, or that the filters used several times due to the ground coffee, which penetrates into the pores, consuming and regularly cleaned, and at some point must be replaced.

PRESENTATION OF THE INVENTION

It is accordingly an object of the present invention to provide an improved apparatus for brewing an extraction beverage, in particular coffee or tea from a brewing powder.

The object is achieved in that the device is a substantially rotationally symmetrical (even slight deviations from the rotational symmetry are possible) brewing container with a substantially perpendicular to the axis of symmetry arranged bottom (it is also possible, for example, a V-shaped bottom) and a Has laterally circumferentially upstanding side wall, wherein the brewing container is rotatably mounted about its axis of symmetry and can be driven by a motor or by hand. In other words, a brewing container is provided, which can be rotated about its axis so that the brewing liquid is substantially completely driven to the side wall due to the centrifugal force generated thereby substantially to form a cylindrical inwardly facing surface. Furthermore, the device according to the invention is characterized in that the brewing container can be closed on the opposite side to the bottom forming a brewing chamber with a lid, just to make it possible to conduct the brewing liquid as described above in the sense of a sedimentation centrifuge in the sense of a hollow circular cylinder ,

Furthermore, the invention is characterized in that an at least in the region of its radial end extending in the radial direction and open, spaced from the side wall at this point discharge line is arranged, through which upon rotation of the filled with brewing water and brewing broth the brewed extraction beverage decanted off without further support and discharged by itself radially inward. The distance of the discharge line from the side wall at this point is just set so that only extract but not coffee powder or tea powder or tea leaves are discharged through the discharge line. Only supernatant liquid, but not solid particles are thus removed. As a result of the rotation is in the sense of a peeler centrifuge, the extract of itself radially pressed through the discharge line inside and accordingly can be dissipated in a very simple manner and above all very fast coffee or tea. Due to the very efficient centrifugation, there is also a reliable separation of solid particles and extract. The brewed extraction beverage is discharged or pressed through the discharge line essentially due to the hydrostatic pressure generated by the centrifugal forces. In other words, can be dispensed with a pump or the like for the discharge of the extraction beverage.

Such a device can produce coffee at an extremely high speed (for example, 11 in 2 minutes) with high quality without the need for elaborate filter constructions. This is particularly advantageous if a lot of freshly brewed coffee has to be made available within a short time. According to a first preferred embodiment, the side wall is designed to widen conically starting from the bottom (to a certain extent V-shaped). It is also possible that the bottom is not present and the whole container is V-shaped conically tapered downwards tapering).

A further preferred embodiment, in particular in connection with such a conical design, is characterized in that the cover comprises an inner separating cover and an outer sealing cover, wherein the sealing lid seals the brewing container substantially at its end opposite the ground and arranged between the seal cover and the bottom, preferably arranged parallel to the seal cover separating cover on the bottom side facing the brewing space leaving a disposed between the side wall and separating cover outlet gap and limited on the side facing the seal lid a separation space, wherein the discharge line is arranged in the separation space ,

Thus, for the brewing process, two separate rooms are available, brewing room and separation room, separated by said separating lid.

The brewing process (contact time of the water with the coffee) can generally u.a. can be easily controlled by changing the speed. This results in stronger or weaker coffee.

The gap between the separator cover and side wall to some extent forms part of a filter or acts as a filter, so a first separation of solids and liquid can take place at this gap, and a second separation in the context of the so-called sedimentation centrifuge separation space, where the discharge line decanted off the supernatant.

In order to ensure the most efficient transfer from the brewing chamber into the separation chamber, the device preferably has the closed position of the device at the location of the gap or above it (ie in the separation space) via a further widening bevel of the side wall, wherein then the Side wall merges into a cylindrical portion, on the radial inside of which preferably only in the radial direction open end of the discharge line is arranged (the opening can also be open against the direction of rotation and to some extent peel off the protruding).

According to a further preferred embodiment, the device is characterized in that the brewing container is arranged as part of a preferably rotatably mounted for emptying lower unit, and that the seal cover, the separating cover, the discharge line and a feed line for the brewing water in a respect to this lower unit under opening of the combustion chamber slidable or rotatable (about a horizontal axis, for example) upper unit are stored. A central axial feed line arranged on the axis of symmetry of the device can be present, which passes through both the sealing cover and the separating cover (if present) and is open towards the brewing chamber. Thus, for example, in a first step, the brewing chamber can be rotated after coffee has been poured, so that the coffee is arranged along the side wall. Subsequently, the hot water can be supplied via this central feed line, which does not rotate, whereby it first strikes the ground, is carried out there, then flows through the coffee along the conical side wall from bottom to top in an optimal extraction process and then through exits the above-mentioned gap in the separation space.

The discharge line may have at its radial end a radial portion, which then passes, preferably via a transfer channel, in an axial section.

A further preferred embodiment is characterized in that the brewing container is fixed to the brewing chamber opposite side of the bottom of a shaft or formed integrally therewith that this shaft is rotatably mounted and with a motor to a rotational speed in the range of 1000 to 5000 revolutions per minute, preferably in the range of 2500-3000 revolutions per minute for the separation process can be brought.

Alternatively, it is possible to drive without such a wave, the container, for example, directly through a V-belt. The motor can also act directly on such a shaft, possibly via a transmission, but it is also possible to design the drive indirectly via a V-belt or a toothed belt.

A further preferred embodiment is characterized in that the radial position of the radial end of the discharge line is designed to be adjustable. Thus it is possible, to a certain extent, to adjust the height of the decanting and, for example, to react to this, when a lot of solid material is discharged through the gap into the separation space (this depends, for example, on the degree of grinding). The opening may be round or slot-shaped, and it may also have a grid at its end.

Further preferably, the device is characterized in that a supply line for the brewing water is arranged, which passes through the lid, if present sealing cover and separating cover, wherein the feed line is preferably arranged on the symmetry axis of the device.

Preferably, the device is further characterized in that the arranged between the side wall and the separator cover outlet gap is designed to be adjustable in its gap opening. Again, this adjustability can be reacted to different powders for the extract, typically a fine freeness requires a narrow gap, on the other hand leads to a slower process and vice versa. In the preferred conical configuration of the side wall, the gap width is adjustable via the penetration depth of the separating cover.

Furthermore, the present invention relates to a method for brewing an extraction beverage from a brewing powder, more preferably from coffee powder, using a device as described above. The process is preferably characterized in that, with the lid open, the brewing powder is introduced into the open, preferably with its symmetry axis vertically arranged brewing container, then the lid is closed, then hot brewing water is preferably conducted via an axial feed line into the brewing chamber, either before, during or after the feeding of the hot brewing water, at least the brewing container is set in rotation (the order determines the type of extraction, preferably the dry powder is first rotated until it collects on the wall, and then the water is first supplied) that the brewing powder and the brewing water are arranged substantially exclusively along the side wall as a result of the centrifugal forces, and that the supernatant extraction beverage is skimmed off via the discharge line and removed in the radial direction without further support.

A preferred embodiment of the method is characterized in that the lid comprises an inner separating cover and an outer sealing cover, wherein the sealing lid seals the brewing container substantially at its bottom opposite end and rotates with the brewing container with and between Seal lid and bottom arranged, preferably arranged parallel to the seal cover and also normally co-rotating separator lid on the bottom side facing the brewing space, leaving a between side wall and separating cover arranged exit gap bounded and bounded on the side facing the seal lid a separation space, the discharge line arranged in the separation space is, and that the extraction beverage passes from the brewing chamber through the gap in the separation space and there is skimmed off and discharged through the discharge line.

After the brewing process, the lid can be tilted or moved under opening the filling opening of the brewing container, and the spent brewing powder can be removed from the brewing container, preferably by the brewing container is tilted, so that the spent brewing powder under the action of gravity down falls the brewing container, which may optionally be supported by a special tool this process to some extent in the sense of peeling out and the container then again, possibly. At lower speeds, can be rotated about its axis.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

In Fig. 1, only one half of the circular symmetrically configured device according to the invention is shown in an axial section in a schematic manner. The device comprises around a symmetry axis 1 around a brewing container 3, which is bounded below by a bottom 4 and which has a circumferentially extending conically upwardly extending side wall 5. At its upper end, the inner wall of this side wall 5 widens slightly further in a region 10, in order then to pass in the uppermost section 8 into a cylindrical region, where the inner wall 9 is cylindrical.

The brewing container 3 is shown in this illustration in the closed position, which means that a lid is placed on the otherwise open-topped construction and this closes the brewing container 3. This cover comprises, on the one hand, a separating cover 12, which runs essentially in a radial direction and is typically designed as a circular disk. This separating cover 12 protrudes into the interior of the container 2 just far enough that a small outlet gap 14 remains between its radially outer edge and the inner surface of the side wall 5 arranged there, the function of which will be described below.

Further above and connected via a variable or rigid connecting element 21 with the separating cover 12, a sealing cover 15 is arranged, which is typically also formed as a circular disk. At the radial edge of this seal cover has a seal 16, which may be arranged for example in a circumferential groove. The outer diameter of this seal cover 15 corresponds substantially to the inner diameter of the region 9, the seal cover engages in the upper portion 8 and seals the entire below arranged region of the brewing container.

Thus, the interior of the brewing container 3 separates into two different areas, namely in the lower brewing chamber 11 and the separating space 13 arranged between the separating lid and the sealing cover 15.

In this separation chamber 13, a discharge line 17 is arranged for coffee. This discharge line extends in the radial direction, i. it has a radial portion 19. This radial portion 19 does not extend in the radial direction to the inner wall of the side wall 5, the radially outer end 18 of the conduit 17 is arranged at a distance from the wall 9. This distance ensures that only the supernatant liquid is decanted off or peeled off.

The radial section 19 typically transitions into an axial section 20 over which the finished brewed coffee is removed.

At the bottom of the brewing container 3 has an axial drive shaft 6, this is for example connected to a belt edge 7, here, for example, a toothed belt attack, which is driven by a motor (not shown). Arranged centrally and arranged on the axis 1, passing through the two covers 12 and 15, a supply line 2 for hot brewing water.

This construction now works in its essential elements according to the following principle:

In a first step, in the quiet container 3, in which case the lid 12, 15 are removed upwards, or filled through an opening of this cover, coffee powder, so that this collects on the bottom 4. In a next step, the brewing container 3 is brought to a high rotational speed. The rotational speed is so high that the coffee is arranged along the side wall 5 due to the centrifugal force, as shown schematically by the dotted line 22. Typically, the gap 14 is too small for the dry coffee powder to enter the region 13 through this gap 14.

In a next step, hot brewing water is fed centrally from above through the line 2. This falls onto the floor 4 and, after contact with this floor 4, is also carried along the floor 4 to the side wall as a result of the centrifugal force. Subsequently, also as a result of the centrifugal force, the brewing water is driven along the obliquely widening side wall 5 through the coffee powder passing upwards. Thus, the brewing water successively penetrates the coffee powder, which (the rotation is always maintained) is located along the wall 5. After some time, the brewing water, which now represents an extract, arrives at the gap 14. It will pass through this gap 14 therethrough, accelerated along the flank 10 to enter the area to the left of the cylindrical wall 9 and there also in the sense of a hollow cylinder along this wall to align, as shown schematically by the dotted line 23. The extract is now in the separation room 13.

A small portion of small coffee grains may be carried along by the gap 14 together with the liquid and may also reach the separation chamber 13. However, in the sense of a sedimentation centrifuge, these particles will now be arranged specifically only in the near-surface region to the section 9. As soon as this circular ring of extract has reached a height such that the tip 18 of the line 17 is immersed in the liquid, the extract is automatically and without consequence due to the additional hydrostatic pressure generated by the centrifugal force and / or due to the rotation and the angular momentum Necessity of a pump or the like transported through the conduit 17 radially inwardly and then guided axially upwards and to an outlet.

Thus, an extremely fast, and still the entirety of the coffee powder extracting coffee extraction process is provided, which also has the advantage, so to speak, a first filter stage (gap 14) to have, which is easily cleaned automatically with each new process, since this gap is completely opened and closed every time the device is opened and closed. In addition, the device has the advantage that a second stage of the separation takes place in the sense of a peeler centrifuge in the separation space 13. Fine solid particles, which optionally pass through the gap 14, are also separated in this separation centrifuge, since they respectively on the floor resp. accumulate on the outermost wall 9 and will not survive and accordingly can not be discharged through the conduit 19 or can be dragged by liquid.

A specific possible construction of such a device is to be explained in the individual process steps with reference to the following figures. Fig. 2 shows such a device in the open, not yet filled with coffee state. The device has a base 26 in which the brewing container 3 is mounted. The brewing container 3 is shown here open, i. the filling opening 27 is open. The brewing container is rotatably mounted in this substructure 26, this via a motor which engages the pulley 7.

At this base 26 pivotally mounted about an axis 28 is a superstructure 24 is present. This superstructure can be pivoted about the axis 28 against the brewing container in this closing manner and closed with a bayonet closure 25.

The superstructure 24 has on the one hand on the two covers 12 and 15, and on the brewing water inlet 2 and the discharge line 17. At the top of the superstructure 24 while a connection head 32 is arranged, which has on the one hand via an inlet 29 for brewing water, and, on the other hand, via an outlet 30 for brewed coffee. The function of the single element of the superstructure 24 will be described in more detail below.

In Fig. 3 is now in principle the same situation as in Fig. 2dargestellt, but now in the brewing chamber 11 substantially dry coffee powder 31 was filled. It collects on the floor 4 and forms there first a pile. In Fig. 4is now shown how the superstructure 24 has been pivoted down to the brewing container 3, this is done in a rotation about the axis 28, the lever 25 is then reversed about an axis 38, so that a hook of the lever 25 surrounds a transverse pin 37 and so the superstructure 24 is locked to the base 26. It can now be recognized in this representation, as in the upper region of the superstructure 24, the different lines are formed as coaxially extending lines. On the one hand, there is the centrally extending brewing water line 2, the axial section 20 of the discharge line 17 is designed here as a ring line, whose inner wall is formed by the outer wall of the conduit 2.

On the other side, the line 20 is bounded on its outer side by an outer cylinder 35, which also has a connection opening 34 at a certain rotational position.

Fig. 4 shows a situation in which the lid is pivoted only down but not completely closes the brewing chamber. In other words, the seals 16 of the lid 15 are still above the upper portion 8. To close the device, the lid construction within the superstructure 24 is now shifted a little further down, as can be seen with reference to FIG. 5. Here now the entire cover construction is moved so far down that the seal cover 15 engages with its seal 16 in the upper portion 3 and thus seals the entire below arranged area.

Now, the container 3 is rotated so fast, so that the coffee powder on the side wall 5 arranges, as shown schematically by the reference numeral 42. The coffee powder is initially dry in this condition. In this case, the separating lid 12 rotates with the brewing container 3, and likewise the sealing lid 15 rotates with the device.

There are now two bearings 43 and 44, over which the central portion of the lid does not rotate. In other words, rotate with the brewing container 3 only the elements 12 and 15, the element 15 is rotatably mounted on the bearing 44 with respect to a centrally disposed element 39, 40 and the separating cover 12 is about the bearing 43 with respect to this central element 39, 40th rotatably mounted, the central element does not rotate. In fact, it is of course crucial for the function of the discharge line 17 that this does not rotate.

Now, in a situation where the coffee is arranged on the edge of the wall 5, 2 hot brewing water supplied via the central line, this falls, as already described above, on the floor 4 and then works successively along the concave side wall upward until it comes to the gap 14, where it leaves the actual brewing chamber as an extract.

As can be seen from Fig. 6, passes through the gap 14, the extract now up in the separation chamber 13. Since there continues to rotate, the liquid collects in the sense of a circular ring until its level reaches a level that she does not touch the top 18 which starts with rotating wire 17. Now, as a result of the additional hydrostatic pressure and / or rotation generated by the centrifugal force, the extract, with the solids remaining on the wall 8, is driven radially along the arrows 46 and then up a short section and again via a transfer channel 36 guided in an axial section 20.

If the brewed coffee is discharged, then, as will be illustrated with reference to FIG. 7, first the lid construction is slightly shifted upwards, so that the upper portion 8 and the seal 16 are disengaged and then the lid as a whole can be tilted. With reference to Fig. 7 it can be seen how preferably at the upper inner edge of the region 8, a chamfer or chamfer 45 is arranged, which ensures that the insertion of the seal cover 15 together with the seal 16 is possible without problems.

In a next step, as shown in Fig. 8, the superstructure 24 is pivoted about the axis 28 with opening of the brewing chamber 3. The coffee grounds 47 remains as a relatively dimensionally stable filter cake typically in the form of a ring, as shown in Fig. 8, in the brewing container.

As this filter cake 47 as I said has the tendency to be quite dimensionally stable and sticky, according to this specific embodiment, in a next step, as shown in Fig. 9, the brewing container 3 is pivoted about a horizontal axis and position 49 tilted. Since also typically the filter cake resp. The wet coffee grounds typically does not automatically emerge from the brewing chamber due to gravity, is now intervened with the aid of a peeling tool 48 in the interior of the container 3 and this peeling tool 48, as illustrated with reference to FIG. 10, completely inserted into this interior. The outer contour of the peeling tool is preferably adapted to the contour of the inner wall of the brewing container 3, and now in a next step, the brewing container is again rotated about its axis of symmetry to help the motor, wherein now the peeling tool removes the entire filter cake from the container 3 and the Coffee grounds as shown by the arrow 50, falls by gravity down.

Anschiessend the brewing can be given up again in a position as shown in Fig. 2, and the machine is typically ready for use without further purification steps for the next extraction process. The machine has the usual additional elements, as they are usually present in a coffee machine, so it can have a grinding tool, which grinds the coffee directly into the brewing chamber 11 into it, it has a motor, a container for receiving the coffee grounds via an exhaust pipe for the finished brewed coffee, via a brewing water heating unit connected to the inlet 29, via a power supply and via a typically central controller to trigger the individual steps.
