Description
APPARATUS FOR PREPARING AN INFUSION
FROM A LIQUID AND AN INFUSIBLE INGREDIENT
This invention is concerned with an apparatus for preparing an infusion from a liquid and an infusible ingredient. For example, the apparatus may be for preparing coffee or tea in a drinks dispensing machine, in which case the apparatus is known as a "brewer".
In the preparation of infusions from a liquid and an infusible ingredient, a major problem arises concerning the disposal of spent ingredient from an infusion chamber of the apparatus which is arranged to receive the infusible ingredient and the liquid. The infusion chamber defines filtration means through which the liquid but not the ingredient can leave the chamber and after the infusion process spent ingredient is left in the chamber. This spent ingredient must be removed before a further infusion process can take place in the chamber, both on hygiene grounds and to maintain the quality of successive infusions. One solution to this problem has been to be provide the filtration means in the form of a cup and to provide means for inverting the cup to remove spent ingredients.This solution, however, requires a complex and bulky mechanism which occupies a considerable space in a dispensing machine. In another solution, a blade scraps the filter after each infusion but this also requires a complex mechanism. Another solution has been to use a filter which is replaced after each infusion process, the filters, e.g. of paper, being fed successively to the infusion chamber and being successively removed with spent ingredient adhered to them. This solution, however, also requires a complex and bulky mechanism and considerably increases the bulk of waste formed by the machine.
It is an object of the present invention to provide an apparatus for preparing an infusion from a liquid and an infusible ingredient which is simple and compact and which does not make use of a disposable filter.
The invention provides apparatus for preparing an infusion from a liquid and an infusible ingredient, comprising an infusion chamber arranged to receive the infusible ingredient and the liquid, the infusion chamber defining filtration means through which the liquid but not the ingredient can leave the chamber, rotating means operable to rotate the infusion chamber to thereby dry spent ingredients remaining in the infusion chamber after the liquid has left the chamber; and separating means operable to separate parts of the chamber to thereby open at least one opening in the chamber, the opening being disposed so that continued operation of the rotating means causes the dried spent ingredient to be projected out of the chamber through said opening.
Apparatus according to the last preceding paragraph can be made in a compact form and is simple and reliable in operation. An electric motor can be employed for the rotating means which is reliable and simple to operate.
As the spent ingredient is first dried and then ejected with considerable force from the infusion chamber, the apparatus is very hygienic since very little spent ingredient remains in the infusion chamber after each infusion process. The centrifugal force causes a squeezing action which dries the spent ingredients effectively. Furthermore, the rotation of the infusion chamber can be utilised at other times during the infusion process to give further advantages which are referred to below.
Preferably, said rotating means is operable to rotate the infusion chamber about a substantially vertical axis disposed centrally of the chamber. This gives a balanced arrangement.
Preferably said rotating means is arranged to apply a faster rotation to project the spent ingredient out of the chamber than the rotation applied to dry the spent ingredient. In this arrangement, the spent ingredient is dried by the liquid being squeezed out of the ingredient by the action of the centrifugal force and then, when the parts of the chamber have been separated, is subject to high force to project the spent ingredient out of the chamber.
Advantageously, the rotating means is also operable to rotate the infusion chamber during the supply thereto of a metered quantity of the infusible ingredient to thereby distribute the ingredient around the chamber. In this way, a more efficient infusion process can be achieved since when the liquid enters the chamber the ingredient is already evenly distributed rather than being located in one part of the chamber only.
In order to force the liquid into contact with the ingredient in the infusion chamber in order to ensure a more efficient infusion process, the rotating means may also be operable to rotate the infusion chamber during supply thereto of the liquid which flows through the chamber, over the ingredient, and leaves through the filtration means.
Advantageously, the rotating means, in addition to rotating the infusion chamber, may drive a pump which is operable to pump liquid from a container into the infusion chamber. This arrangement enables a separate pump-driving motor to be dispensed with. The container may be positioned immediately beneath the infusion chamber and the pump may be a centrifugal pump mounted on the underside of the bottom wall of the chamber. This arrangement gives the advantage that the liquid can be circulated through the infusion chamber several times in a single infusion process giving a better infusion.
Different strengths of infusion can be given by varying the rotation speed and/or the time during which the liquid is circulated through the chamber. The use of such a centrifugal pump can also be used to maintain a predetermined volume of liquid in the infusion process since the pump will drive liquid into the chamber until the level of the liquid in the container falls below the inlet of the pump and will not resume pumping liquid until liquid falling through the filtration means into the container raises the level of the liquid to the inlet once more.
Advantageously, the separating means may be arranged to be operated by the action of the rotating means. Such an arrangement dispenses with the need for a separate drive mechanism for the separating means. In one possible embodiment, the separating means comprises a pin and slot camming arrangement so arranged that operation of the rotating means in one direction of rotation causes the parts of the infusion chamber to be separated and operation of the rotating means in the opposite direction of rotation causes the parts of the infusion chamber to be moved together into sealing engagement. Instead of a pin and slot camming arrangement, a screw-threaded connection may be used.Thus, after rotating in one direction to dry the ingredient, the direction of rotation of the rotating means would be reversed to open the opening and, after ejection of the spent ingredient, the direction of rotation would be returned to its first direction to close the opening again. The chamber may alternatively be closed at the beginning of the next cycle of operation of the apparatus. In another possible embodiment, a governor device may be arranged so that operation of the rotating means above a predetermined rotational speed causes the parts of the infusion chamber to be separated. Thus, the raising of the rotational speed between drying the ingredient and projecting it from the chamber may be utilised to create the opening.
In another alternative, an inertia arrangement may be used in which slowing of the rotation means creates the opening.
The filtration means may comprise a mesh covering a plurality of holes in the bottom wall of the chamber arranged at the outer edge of the chamber in a circle about said substantially vertical axis. Alternatively the filtration means may comprise holes each defined partly by each of the parts of the chamber which are separated by the separating means. The arrangement of the filtration means in a circle assists an even infusion process particularly where the infusion chamber is rotated during the passage of liquid through the infusion chamber.
The upper wall of the infusion chamber may be arranged to slope downwardly towards the edge of the chamber. This arrangement deflects liquid towards the filtration means and assists in deflecting the spent ingredient towards said opening.
The apparatus may also comprise a catching chamber surrounding said infusion chamber and having an annular opening facing the infusion chamber so that spent ingredient projected through the opening of the infusion chamber enters the catching chamber. The apparatus may also comprise means for causing an air flow in the catching chamber to purge it. Said means for causing an air flow may comprise a plurality of fins mounted on the exterior of the infusion chamber for rotation therewith.
The invention also provides a method of preparing an infusion from a liquid and an infusible ingredient, the method comprising the steps of:a) introducing a metered quantity of ingredient into
an infusion chamber which defines filtration means
through which the liquid but not the ingredient
can leave the chamber; b) introducing the liquid into the chamber so that the
liquid flows over the ingredient and passes out of
the chamber through the filtration means; c) rotating the chamber to dry spent ingredient in the
chamber; d) providing an opening in the chamber; and e) rotating said chamber to project the spent
ingredient through said opening out of the chamber.
In a method according to the last preceding paragraph, the spent ingredient is removed from the chamber in an efficient and hygienic manner.
In order to improve the efficiency of the process, the rotational speed in step e) may be greater than that in step c).
In order to improve the efficiency of the infusion process, the chamber may also be rotated during one or both of steps a) and b) so that during step a) the ingredient is distributed around the chamber and in step b) the liquid flowing through the chamber is forced into contact with the ingredient and out through the filtration means.
In step b), the liquid may be introduced into a container disposed immediately beneath the infusion chamber so that liquid passing out of the container through the filtration means falls into the chamber and the liquid may be pumped from the container into the chamber. This arrangement enables the liquid to be circulated two or more times through the chamber to improve the infusion process. The number of times that the liquid is circulated through the chamber may be varied to alter the strength of the infusion as desired.
The liquid may, conveniently, be pumped by means of a centrifugal pump mounted on the underside of the infusion chamber which is operated by rotation of the chamber.
Advantageously, in step d) a portion of the infusion chamber is moved vertically relatively to the remainder of the chamber to provide said opening. This arrangement provides a simple way of providing said opening.
There now follows a detailed description, to be read with reference to the accompanying drawings, of an apparatus for preparing an infusion from a liquid and an infusible ingredient which is illustrative of the invention and a method of preparing an infusion from a liquid and an infusible ingredient which is illustrative of the invention in its method aspects. It is to be understood that the illustrative apparatus and illustrative method have been selected for description by way of example and not of limitation of the invention.
In the drawings:
Figure 1 is a vertical cross-sectional view taken through the illustrative apparatus; and
Figure 2 is a graphical representation against time of the speed of rotating means of the illustrative apparatus used in the illustrative method.
The illustrative apparatus 10 shown in Figure 1 is for preparing an infusion from a liquid, specifically hot water, and an infusible ingredient, specifically tea or coffee. The apparatus 10 comprises an infusion chamber 12 which is arranged to receive the infusible ingredient and the liquid. The chamber 12 is defined by an upper member 14 and a lower member 16 which are movable vertically relative to one another between a position in which they engage one another in a sealing manner (this position is shown in Figure 1) and a separated position (not shown). The lower member 16 is generally in the shape of a horizontal disc with a central boss 20 projecting downwardly therefrom.A vertical bore passes through the lower member 16 centrally of the boss 20 and a shaft 22 is received in this bore and is secured to the boss 20 by means of a screw 24 received in a horizontal threaded bore in the boss 20. The lower member 16 is, thus, supported on the shaft 22. Around the edge of upper surface thereof, the lower member 16 has an upwardly facing recess 26 in which an annular seal 28 is mounted. The seal 28 is arranged to seal the gap between the upper and lower members 14 and 16 when they are in engagement with one another.
The infusion chamber 12 defines filtration means through which the liquid, but not the ingredient, used in making the infusion can leave the chamber 12. The filtration means is provided by a mesh 34 covering a plurality of holes 30 in the bottom wall of the chamber 12. These holes 30 are in the lower member 16 and are arranged at the outer edge of the chamber adjacent to the recess 26 in a circle about a central axis 32 of the shaft 22. In the illustrative apparatus 10, there are twenty-four of the holes 30. The mesh 34 extends across the upper surface of the lower member 16 to cover all the holes 30 and contains a large number of small holes which allow the liquid to pass therethrough but not the ingredient. In modifications of the apparatus 10, each hole 30 may be provided with its own individual mesh. In another alternative embodiment, the filtration means may be provided by holes which are each defined partly by the upper member 14 and partly by the lower member 16 when the parts are in engagement.
The upper member 14 of the infusion chamber 12 has a central disc-shaped portion 40 extending horizontally above the lower member 16. The portion 40 has a central boss 42 projecting downwardly therefrom. The boss 42 has a central bore therethrough in which a cylindrical sleeve 44 is received. The sleeve is secured to the boss 42 by a screw (not shown) similar to the screw 24 in the boss 20. The sleeve 44 is telescopically received on the shaft 22 and can slide vertically relative thereto. The boss 42 is received in a recess 46 in the top of the lower member 16 which extends downwardly into the boss 20. A pin 50 is mounted on the sleeve 44 and projects into a sloped slot 52 in the exterior surface of the shaft 22.
The pin 50 and the slot 52 together form a camming arrangement which provides separating means of the apparatus 10 operable to separate the parts 14 and 16 of the chamber 12 to thereby open at least one opening in the chamber. The camming arrangement is so arranged that rotation of the infusion chamber 12 about the axis 32 in one direction of rotation causes the parts 14 and 16 to be separated in a vertical direction with the part 16 moving downwardly away from the part 14. Rotation in the opposite direction causes the parts 14 and 16 to move together into sealing engagement.
In an alternative embodiment of the apparatus 10, the pin and slot arrangement 50 and 52 is replaced by a screw-threaded connection so arranged that rotation in one direction causes the parts 14 and 16 to be separated and rotation in the opposite direction causes the parts to be moved into sealing engagement. In another alternative embodiment, a governor device replaces the pin and slot arrangement 50 and 52, and is so arranged that rotation above a pre- determined rotational speed causes the parts 14 and 16 to be separated. If the rotational speed falls below said predetermined rotational speed, the parts 14 and 16 return to sealing engagement. For example, the governor device may act on a cam which is opposed by a spring. A device working on an inertia principle may alternatively be used.
The upper member 14 of the infusion chamber 12 also comprises an upstanding annular portion 56 integral with the portion 40 thereof and upstanding therefrom, and a downwardly-inclined portion 59 integral with the portion 56 and with an annular outer portion 54 of the member 14 arranged to engage the seal 28. The portions 40 and 56 define a plurality of holes 58 at the junction of the portions 40 and 56 which provide entrances into the infusion chamber 12 for the ingredient. In the apparatus 10, there are twelve holes 58.The portion 59 of the member 14 forms a portion of the upper wall of the infusion chamber 12 which slopes downwardly towards the outer edge of the chamber and, when the parts 14 and 16 are in engagement with one another, the chamber 12 has a cylindrical inner portion around the boss 42 and an annular outer portion of triangular vertical cross-section beneath the portion 59.
The illustrative apparatus 10 also comprises rotating means in the form of an electric motor 60 which is operable to rotate the infusion chamber 12 about the axis 32 which is substantially vertical and is disposed substantially centrally of the chamber 12. The motor 60 is mounted in a vertical disposition on a support member 62 and has its output shaft 64 projecting downwardly and coupled to the sleeve 44 which is in turn coupled to the shaft 22 by the camming arrangement 50, 52, although as aforementioned the shaft 22 can move vertically relative to the sleeve 44. A downward projection 66 of the support member 62 is cylindrical and surrounds the sleeve 44 and supports bearings 68 on which the sleeve 44 can rotate.
The motor 60 is arranged to rotate the chamber 12 about the axis 32 after the infusion process to thereby dry spent ingredient remaining in the infusion chamber 12 after the liquid has left the chamber and to cause the dry spent ingredient to be projected out of the chamber through the opening created when the parts 14 and 16 of the chamber are separated. The ingredient is forced by centrifugal force on to the sloping portion 59 of the member 16 and when the members 14 and 16 are separated slides down the portion 59 to the opening.
The motor 60 is controlled so that it causes a faster rotation to project the spent ingredient out of the chamber than the rotation it applies to dry said spent ingredient. The motor 60 is also operable to rotate the chamber 12 during the supply thereto of a metered quantity of the infusible ingredient through the holes 58 to thereby distribute the ingredient around the chamber 12. The ingredient is metered by metering means of the apparatus (not shown) of conventional construction which drops the ingredient into the annular chamber formed around the projection 66 within the annular portion 56 of the upper member 14 of the infusion chamber 12. Furthermore, the motor 60 is also operable to rotate the infusion chamber during the supply thereto of the liquid which flows through the chamber, over the ingredient and leaves through the filtration means.This rotation serves to drive the liquid outwardly from the centre of the infusion chamber 12 and forces it into contact with the ingredient and through the filtration means, thereby improving the infusion process.
The motor 60, in addition to rotating the infusion chamber 12, drives a pump 80 which is formed in the boss 20 and is operable to pump liquid from a container 82 into the infusion chamber 12. The container 82 is positioned immediately beneath the infusion chamber 12 so that the liquid passing through the filtration means falls into the container 82. The pump 80 is of the centrifugal type having an inlet 84 beneath the intended level of the liquid in the container 82, a passage 86 extending upwardly in the boss 20 into the recess 46, and an exit 88 into the chamber 12. The pump 80 is thus a centrifugal pump driven by the motor 60 and is mounted on the underside of the bottom wall of the chamber 12.
As aforementioned, the rotation of the infusion chamber 12 is effective to operate the separating means formed by the pin 50 in the slot 52 so that the separating means is arranged to be operated by the action of the motor 60.
The apparatus 10 also comprises a catching chamber 90 surrounding said infusion chamber 12 and having an annular opening 92 facing the infusion chamber 12 so that spent ingredient projected through the opening of the infusion chamber 12 enters the catching chamber. The apparatus 10 also comprises means in the form of a fan (not shown) for causing an air flow in the catching chamber 90 to purge it. Alternatively, such means may comprise fins or vanes mounted on the underside of the portion 54 of the member 14. The spent ingredient is collected in a container (not shown) for later disposal.
Figure 2 shows a graph of the speed of the motor 60 against time which illustrates the operation of the illustrative apparatus 10 according to the illustrative method. In the illustrative method which is for preparing an infusion from a liquid and an infusible ingredient, the method comprises the steps of: a) introducing a metered quantity of ingredient into
the infusion chamber 12 through the holes 58 while
rotating the chamber 12 to distribute the ingredient
around the chamber, this occurs in portion 101 of
the graph of Figure 2; b) introducing a predetermined volume of liquid into
the chamber 12 so that the liquid flows over the
ingredient and passes out of the chamber 12 through
the filtration means, to achieve this the liquid is
introduced into the container 82 through an inlet
pipe 83 while still rotating the motor 60, this
occurs in portion 102 of the graph.When the level
of the liquid in the container 82 reaches the inlet
84 of the centrifugal pump 80, liquid is pumped into
the infusion chamber 12, flows over the ingredient
and passes back into the container 82 through the
filtration means (portion 103). The speed and/or
duration of rotation can be set to give a
predetermined strength of infusion; c) rotating the chamber about the substantially
vertical axis 32 to dry spent ingredient in the
chamber. This takes place after the liquid has
been drained from the container 82 through an outlet
85 to an extent such that the level of the liquid is
below the pump 80 and occurs in the portion 104 of
the graph; d) providing an opening in the chamber at the furthest
part of the chamber from the axis 32. This is
achieved by operating the separating means by
reversing the direction of rotation of the motor so
that the camming effect of the pin 50 and slot 52
lowers the member 16 relative to the member 14,
portion 105; e) rotating the chamber 12 about said axis 32 to
project the spent ingredient through said opening
into the catching chamber 90, portion 106.
In the illustrative method, the rotational speed of the motor 60 in step e) is greater than that in step c) and the chamber is also rotated during the steps a) and b).
