Description

[Technical field]

[0001] The field of the invention relates to beverage preparation machines by centrifuging capsules containing the ingredients of the beverage to be prepared.

[0002] For the purposes of this specification, "beverage" is intended to include any liquid substance suitable for human consumption, such as tea, coffee, hot or cold chocolate, milk, soup, baby food, etc. "Capsule" is intended to include any container, such as a package for containing pre-portioned beverage ingredients, such as flavor ingredients, where the package forms an enclosure of any material, in particular airtight or permeable materials, porous or non-porous materials (e.g. plastic, aluminum, recyclable and / or biodegradable packaging), as well as any shape and configuration, including soft pods or rigid cartridges containing the ingredients. [Background technology]

[0003] Some beverage preparation machines use capsules that contain the ingredients to be extracted or dissolved and / or ingredients that are stored in the machine and automatically dispensed or added during preparation of the beverage. Some beverage machines have a filling means that includes a pump for a liquid, usually water, which pumps from a water source either cold water or indeed a liquid that is heated by a heating means, for example a thermoblock.

[0004] In particular, in the field of coffee preparation, machines have been widely developed in which a capsule containing the beverage ingredients is inserted into a brewing device that is sealed around the capsule, injects water into a first face of the capsule to produce a beverage in the sealed volume of the capsule, and releases the brewed beverage from a second face of the capsule where it can be collected in a container such as a cup or glass.

[0005] Brewing devices have been developed to facilitate the insertion of "new" capsules and the removal of capsules during use. Examples of such brewing devices are disclosed in EP 1767129, WO 2009 / 043630, WO 2005 / 004683 and WO 2007 / 135136. The preparation of beverages using centrifugation is also known. Examples of centrifugation processes and corresponding devices are disclosed in WO 2008 / 148601, WO 2008 / 148650, US 5566605, WO 2013 / 007776, WO 2013 / 007779 and WO 2013 / 007780.

[0006] It has also been proposed to facilitate the handling of the capsules by a system for extracting the capsules, independent of the extraction process itself, in particular by motorizing the opening and / or closing of the extraction system for inserting and / or removing the capsules. Examples of such systems are disclosed, for example, in EP 1 767 129, WO 2009 / 113035, WO 2012 / 025258, WO 2012 / 025259, WO 2012 / 041605, WO 2013 / 127476, WO 2014 / 096122, WO 2014 / 096123 and EP 2015185946.9.

[0007] The preparation of beverages using a centrifugal process is also known. Such beverage preparation comprises the steps of preparing the beverage (flavor) ingredients in a capsule, for example powder and / or tea leaves, and rotating the capsule at a speed sufficient to ensure the liquid's interaction with the ingredients while passing a liquid through the capsule and creating a pressure gradient of the liquid within the capsule. Such pressure increases gradually from the center of the capsule towards the periphery. As the liquid passes through the ingredients, such as the coffee layer, extraction of the ingredients, such as the coffee mixture, occurs, resulting in a liquid extract that flows out at the periphery of the capsule. Examples of such systems are disclosed in WO 2008 / 148601, WO 2013 / 007776, WO 2013 / 007779, WO 2013 / 007780 and WO 2017 / 202746.

[0008] It has been proposed to prepare beverages by centrifugal processing along a horizontal axis.

[0009] WO 2015 / 173123 and WO 2015 / 173124 disclose a centrifugal brewing chamber formed between two enclosing parts that are relatively translatable between an open position and a closed position. The enclosing parts cooperate with a pair of jaws that are movable between a capsule retaining position that retains the capsule between the enclosing parts in the open position and a capsule releasing position that releases the capsule. The jaws are actuated by a first actuator and a second actuator that are actuated by the enclosing parts while the enclosing parts are translating relative to each other. The jaws guide the capsule to a position between the enclosing parts in the open position and fix the capsule therebetween. The jaws then release the capsule when the enclosing parts translate together to enclose the capsule, thereby forming a brewing chamber around the capsule. The enclosing parts are rotated about a horizontal axis to centrifuge the capsule in order to prepare a beverage using the ingredients in the capsule. At the end of the beverage preparation, the centrifugation process stops and the surrounding parts translate relatively to an open position, thereby allowing the used capsule to fall out of the surrounding parts. The jaws are then returned to the capsule-holding position. Summary of the Invention

[0010] The present invention relates to a capsule processing machine for preparing a beverage from at least one ingredient. Typically, such a beverage is then dispensed to a user, for example in a user's cup or a user's mug.

[0011] For example, the machine is a coffee, tea, chocolate, cocoa, milk or soup preparation machine, for example configured to prepare a beverage in a beverage processing module including a capsule holder by passing hot or cold water or other liquid through a capsule held in the holder containing an ingredient such as a flavour ingredient of the beverage to be prepared, such as ground coffee, tea, chocolate, cocoa or milk powder.

[0012] Such beverage preparation typically involves mixing a number of beverage ingredients, e.g., water and milk powder, and / or infusion of the beverage ingredients, e.g., infusion of ground coffee or tea with water. One or more of such ingredients may be provided in loose and / or agglomerated powder form, and / or in liquid form, particularly concentrated form. A carrier or diluent, e.g., water, may be mixed with such ingredients to produce the beverage. Typically, a predetermined amount of beverage is produced and dispensed corresponding to one serving (e.g., one scoop) upon user request. Such a serving amount may be in the range of 15-1000 mL, e.g., 25-600 mL, e.g., 40-250 mL, depending on the type of beverage, e.g., the amount to fill a cup or mug. The beverage produced and dispensed may be selected from ristretto, espresso, lungo, cappuccino, caffe latte, americano coffee, tea, etc. For example, the coffee machine may be configured to dispense an adjustable amount of espresso, e.g., between 20 and 60 mL per serving, and / or to dispense an amount of lungo, e.g., in the range of 70 to 200 mL per serving, and / or to dispense an amount of americano, e.g., in the range of 150 to 750 mL.

[0013] An aspect of the invention relates to a capsule processing machine for preparing a beverage from a capsule having a body containing ingredients, the beverage being prepared by passing a liquid through such a capsule and centrifugally driving such a capsule.

[0014] Centrifugal processes for preparing beverages are known, for example, from EP 2000 062, EP 2155020, EP 2152128, WO 2008 / 148646, 2009 / 106175, 2009 / 106589, 2010 / 026045, 2010 / 026053, 2010 / 066736, 2008 / 148650, 2008 / 148834, 2010 / 066705, 2010 / 063644, 2011 / 023711, 2014 / 096122 or 2014 / 096123.

[0015] Typically, the machine includes at least one of the following components: a) a fluid system in fluid communication with the capsule during beverage preparation; b) an in-line heater and / or cooler for temperature conditioning the flow of liquid to be circulated through the capsule, or a batch heater and / or cooler for circulating the liquid to the capsule after being temperature conditioned by the batch heater and / or cooler; c) a pump for pumping liquid into the capsule, in particular a low-pressure pump in the range of 1 to 5 bar, for example 1.5 to 3 bar; d) A motor for driving the capsule in rotation during beverage preparation; e) an electronic control unit, in particular comprising a printed circuit board (PCB), for receiving instructions from a user through an input user interface and for controlling the heater and / or cooler, the pump and the motor(s); and f) one or more sensors for sensing at least one characteristic selected from characteristics of the fluid system, the heater and / or cooler, the pump, the liquid tank, the raw material collector, the flow of the liquid (e.g., via a flow meter), the pressure of the liquid, and the temperature of the liquid, and for communicating such characteristic(s) to the control unit.

[0016] Typically, a capsule has a body that contains the ingredients and a peripherally projecting flange (e.g. a body in the shape of a cup and a lid that covers and extends beyond the mouth of the cup to form a peripherally projecting flange).

[0017] The capsule can have a body that is symmetrical or asymmetrical, conical, frusto-conical, cylindrical, spherical, hemispherical, or truncated spherical, containing an ingredient, for example, ground coffee, tea, cocoa, or other beverage ingredient.

[0018] The capsule may be of the type described above under the heading "Technical Field". The capsule may be, for example, a capsule having a container body, such as a generally cup-shaped, hemispherical or semi-ellipsoidal body, having a flange to which a cover lid (or membrane) is attached, in particular a sealed one. Typically, the capsule contains a beverage ingredient. Examples of suitable capsules are disclosed in WO 2008 / 148601, WO 2008 / 148604, WO 2008 / 148646, WO 2008 / 148650, WO 2008 / 148656, WO 2008 / 148834, WO 2011 / 141532, WO 2011 / 141535, WO 2013 / 072239, WO 2013 / 072297, WO 2013 / 072326, WO 2015 / 044400. The capsule may be of the type marketed by Nespresso under the trademark Vertuo.

[0019] The machine has a first capsule handler and a second capsule handler which are movable relative to the other from a capsule transfer configuration for receiving and / or releasing capsules by the first and second capsule handlers, to a capsule handling configuration for centrifugally processing capsules by rotation of the first and second capsule handlers about a processing axis, and vice versa.

[0020] The machine includes a handler support apparatus for supporting a first capsule handler and a second capsule handler.

[0021] The machine has a machine frame and / or housing which is stationary when the first and second capsule handlers are rotated for centrifugation and which supports the first and second capsule handlers and the handler support device.

[0022] The frame and / or housing may include or be fixed to a bottom, the bottom being configured to rest on an external support surface of such machine when the first and second capsule handlers are rotated about a processing axis for centrifugal processing. The external support surface may be formed by a table top. The processing axis may be at an angle (positive or negative) in the range of 0°-80°, such as 0°-45°, such as 0°-30°, such as 0°-15°, typically substantially 0°, relative to such bottom.

[0023] The frame and / or housing may support a motor connected to the handler support device and at least one of the first and second capsule handlers. For example, the motor is connected to at least one of the support device, the first and second capsule handlers directly or via a transmission device. Typically, such a motor is connected to at least one of the support device, the first and second capsule handlers by at least one of a belt, e.g. a toothed belt, a gear, e.g. a spur gear, and a connecting rod. Such a motor may be configured to relatively move the first and second capsule handlers between a transfer configuration and a processing configuration and / or to rotate the first and second capsule handlers for centrifugal processing of capsules.

[0024] The handler support device is configured to be angularly fixed and remain fixed relative to the first and second capsule handlers and to rotate therewith about the processing axis when the first and second capsule handlers are rotated for centrifugal processing.

[0025] The handler support apparatus may be configured to be angularly fixed relative to the first capsule handler and the second capsule handler in the transfer configuration.

[0026] In such an arrangement, the first and second capsule handlers and the capsules with ingredients are held by and fixed in the rotating handler support and can rotate as one unit. Thus, stresses during rotation resulting from imperfect alignment of the first and second capsule handlers and the capsules or their contents between themselves and / or with respect to the processing axis, as well as the effects of said stresses on other parts of the machine, can be minimized. For example, the stresses of the closing forces on the capsules of the first and second capsule handlers are not amplified by imperfect alignment of the first and second capsule handlers and the capsules or their contents with the processing axis, especially at high rotation speeds. This can advantageously result in a reduction of vibrations during beverage preparation and wear of the machine, in particular wear of the bearing elements that allow the first and second capsule handlers to rotate in the machine. By avoiding vibrations due to imperfect alignment parallel to the rotation, the centrifugal processing of the capsules and the processing of ingredients inside the capsules can also be improved.

[0027] The machine may include an actuator configured to actuate the first and / or second capsule handler to relatively move the first and second capsule handler between a capsule transfer configuration and a processing configuration, for example connected to the machine frame and / or housing such that the first and second capsule handler remain stationary relative to the machine frame and / or housing when rotated for centrifugal processing.

[0028] The actuator may include a motor or handle pivotally mounted on a handle shaft. The motor or handle may cooperate with an actuator slide and / or a translation transmission member, such as a member controlled by the motor or handle via a cam and cam follower connection. Such a member may be directly or indirectly connected to the first capsule handler and the second capsule handler for relatively moving the capsule handlers between the capsule transfer configuration and the capsule processing configuration.

[0029] The machine may include a drive connected to the first capsule handler and the second capsule handler for relatively moving the capsule handlers between the capsule transport configuration and the capsule processing configuration.

[0030] The drive may be secured to the capsule handler in the processing configuration by at least one of a lock, a friction stop, and an over-centre lever or cam mechanism.

[0031] The drive mechanism may include one or more of: a lever, such as a lever pivotally assembled about a pivot axis in a knuckle joint arrangement; a gear, such as a spur gear, and / or a rack, such as a flat rack; a cam and cam follower; a belt, such as a toothed belt; and a drive slide.

[0032] The drive device may connect the first capsule handler and the second capsule handler via the handler support device, for example, the first capsule handler or the second capsule handler may be stationary relative to the handler support device, fixed to the handler support device, or integral with the handler support device.

[0033] The drive may include the above-mentioned drive slide(s) and, optionally, one or more transmission members connecting the drive slide(s) to the first and second capsule handlers for relatively moving the capsule handler between the capsule transfer configuration and the capsule processing configuration. The drive slide(s) may be actuated by the above-mentioned actuator, for example by being connected to the above-mentioned translation transmission members cooperating with the drive slide(s) via grooves and pins.

[0034] The drive slide(s) may include a slide body carrying a pair of arms, each of which defines a groove, the arms extending from the body parallel or substantially parallel to the process axis along opposite sides of the handler support apparatus, for example, the groove being defined by a ridge or protrusion projecting from the slide body, for example around the handler support apparatus.

[0035] The first and second capsule handlers in the processing configuration may define a capsule processing chamber configured to enclose a capsule. For example, one of the first and second capsule handlers forms a cavity shaped to receive a capsule, and the other of the first and second capsule handlers forms a lid configured to close the cavity in the processing configuration. The lid may be spaced from the cavity in the transfer configuration to provide sufficient space between the first and second capsule handlers, for example, to allow the capsule to reach and / or eject from a position between the first and second capsule handlers in the transfer configuration.

[0036] At least one of the first capsule handler and the second capsule handler may include or be associated with an inlet for directing a liquid carrier, e.g., water, into the capsule as the capsule is being centrifuged by rotation. For example, the inlet is associated with a capsule inlet opener, e.g., an inlet piercer, configured to open the capsule, such as a capsule inlet opener having a conduit for directing the liquid carrier from the inlet to the capsule and / or a capsule opener having an exterior surface defining a passage for directing the liquid carrier from the inlet to the capsule.

[0037] At least one of the first capsule handler and the second capsule handler may include or be associated with an outlet for guiding the beverage from the capsule as the capsule is being centrifuged by rotation, for example the outlet being associated with a capsule outlet opener, e.g. an outlet piercing device, configured to open the capsule, such as a capsule opener having a conduit for guiding the beverage from the capsule to the outlet and / or a capsule opener having an outer surface defining a passage for guiding the beverage from the capsule to the outlet.

[0038] One of the first capsule handler and the second capsule handler may include or be associated with both such an entrance and an exit.

[0039] For example, examples of suitable outlets and inlets leading to a beverage collector and then to a machine outlet are disclosed in WO 2015 / 173123 and WO 2015 / 173124.

[0040] The machine may have a capsule insertion passage associated with one or more capsule insertion guides configured to guide the capsule, such as to guide a protruding capsule flange of the capsule towards the aforementioned space between the first and second capsule handlers in the transfer configuration or towards a capsule holding position within the space. For example, the space is associated with a holding device, such as one or more stop members, configured to hold the capsule within the space before being held by at least one of the first and second capsule handlers moving relatively towards and / or to the capsule processing configuration. Suitable stop members are known, for example, from WO 2005 / 004683.

[0041] The capsule insertion passage may be covered by a lid or gate when the first and second capsule handlers are rotated for centrifugal processing, e.g., when the first and second capsule handlers are in the capsule processing configuration, e.g., the lid or gate is formed by the above-mentioned handle or handles configured to relatively move the first and second capsule handlers between the capsule transfer configuration and the processing configuration.

[0042] The capsule insertion guide(s) may also include at least a rotatable portion that is stationary relative to the handler support apparatus and that rotates with the handler support apparatus when the first and second capsule handlers are rotated for centrifugation, for example, the rotatable portion is formed by or assembled to at least one of the first and second capsule handlers and the handler support apparatus.

[0043] The capsule insertion guide(s) may include at least a non-rotating portion that is stationary relative to the machine frame and / or housing when the first and second capsule handlers are rotated for centrifugation, e.g., the non-rotating portion is formed by or assembled to the machine frame and / or housing.

[0044] The handler support apparatus may be pivotally supported by the machine frame or housing via a first bearing, such as a ball or roller bearing or a magnetic or plain bearing, and via a second bearing, such as a second ball or roller bearing or a magnetic or plain bearing. The first and second bearings may be spaced apart along the process axis.

[0045] The first bearing can be located on a side of the handler support apparatus closer to the first capsule handler than the second capsule handler, and the second bearing can be located on a side of the handler support apparatus closer to the second capsule handler than the first capsule handler. The first bearing and the second bearing can be located, for example, at opposite ends of the handler support apparatus.

[0046] The handler support apparatus may have a substantially cylindrical shape extending along the processing axis and at least partially surrounding the first and second capsule handlers. For example, the handler support apparatus may define one or two openings configured to pass capsules into and / or out of the handler support apparatus, for example, by passing the capsules transversely to the processing axis, e.g., via corresponding capsule inlet and / or outlet capsule passages.

[0047] For example, the capsules may be collected in a capsule collector downstream of the exit capsule passage, for example as disclosed in WO 2009 / 074559 or WO 2009 / 135869.

[0048] The machine may have a positioning device configured to position at least one of the first and second capsule handlers and the handler support device at a predetermined angular position about the processing axis when the first and second capsule handlers are in a capsule transfer configuration, e.g. when rotation of the first and second capsule handlers about the processing axis is stopped.

[0049] The positioning device may have a mechanical position coupler, e.g., including a mechanical lock, stopper, or brake, such as a coupler that decouples and / or disengages during rotation of the first capsule handler and the second capsule handler about the processing axis.

[0050] The placement device may include a magnetic position coupler, such as a magnetic coupler having a connector that is stationary relative to the machine frame and / or housing. The stationary connector may be magnetically constrained to a connector that is fixed to or included in at least one of the first and second capsule handlers and the handler support device. For example, one of the connectors may be a magnetic field generating element, such as a permanent magnet or an electromagnet, or a permanent magnet with an electromagnet configured to demagnetize the permanent magnet when the first and second capsule handlers are rotated about the processing axis, and the other of the connectors may include at least one of a ferromagnetic member, a permanent magnet, and an electromagnet.

[0051] Another aspect of the invention relates to a system comprising a capsule processing machine as described above and a capsule having a body containing raw material, the capsule being held by a first capsule handler and a second capsule handler in a capsule processing configuration of the machine supported by a handler support device, whereby the capsule, the first capsule handler and the second capsule handler and the handler support device are angularly fixed relative to one another and rotated for centrifugation.

[0052] A further aspect of the invention relates to a method for preparing a beverage from a capsule having a body containing ingredients in a machine as described above, the method comprising the steps of: transferring the capsule to a first capsule handler and a second capsule handler in a transfer configuration to receive the capsule; placing the first and second capsule handlers in a capsule handling configuration such that a handler support device supports the first and second capsule handlers and the capsules and is angularly fixed relative to one another; a capsule handling device for handling the first and second capsule handlers and supported by the handler support device, the capsules being rotated about a processing axis, the capsules being centrifugally processed, and a liquid being caused to flow through the capsules to produce a beverage, the capsules being angularly fixed relative to one another, the first and second capsule handlers being angularly fixed relative to one another, Includes.

[0053] Yet another aspect of the invention relates to the use of a capsule as a capsule for a machine as defined above or for implementing a system as defined above or for carrying out a method as defined above. to be transferred to a first capsule handler and a second capsule handler in a transfer configuration to receive the capsule; a handler support device that further supports the first capsule handler and the second capsule handler in the capsule processing configuration, whereby the capsule, the first capsule handler and the second capsule handler and the capsule are angularly fixed relative to one another; a capsule support device that is handled by the first and second capsule handlers and supported by the handler support device and centrifugally processed while rotated about a processing axis while liquid is circulated through the capsules to produce a beverage, such that the capsules, the first and second capsule handlers and the handler support device are angularly fixed relative to one another; It will be established.

[0068] The driving devices 31, 32, 33, 34, 35, and 36 may connect the first capsule handler 10 and the second capsule handler 20 via the handler support device 30. For example, the first capsule handler or the second capsule handler 20 is stationary relative to the handler support device 30.

[0069] The drives 31, 32, 32, 33, 34, 35, 36 may comprise the above-mentioned drive slide(s) 36 and, optionally, one or more transmission members 31, 32, 33, 34, 35 connecting the drive slide 36 to the first capsule handler 10 and the second capsule handler 20 for relatively moving the capsule handlers 10 and 20 between a capsule transfer configuration and a capsule processing configuration. The drive slide(s) 36 may be actuated by the above-mentioned actuators 50, 51, 52, for example by being connected to the above-mentioned translation transmission member 52 cooperating with the drive slide(s) 36 via a groove 36' and a pin 52'.
