<1. Overview of Beverage Production Device>
The beverage production device 1 includes a housing 100 that forms an exterior of the beverage production device 1 and encloses an internal mechanism. The housing 100 is roughly divided into a main body portion 101 and a cover portion 102 that covers a part of a front surface and a part of a side surface of the beverage production device 1. The cover portion 102 is provided with an information display device 12. The information display device 12 of the present embodiment is a touch panel type display, and is capable of receiving an input from an administrator of the device or a beverage consumer in addition to displaying various types of information. The information display device 12 is attached to the cover portion 102 via a moving mechanism 12a, and can be moved in a predetermined range in an upper-lower direction by the moving mechanism 12a.
The cover portion 102 is provided with a bean inlet 103 and a door 103a that opens and closes the bean inlet 103. Roasted coffee beans different from the roasted coffee beans accommodated in the canisters 40 can be input to the bean inlet 103 by opening the opening and closing door 103. As a result, it is possible to provide a cup of special beverage to a beverage consumer.
The cover portion 102 of the present embodiment is made of a translucent material such as acrylic or glass, and constitutes a transparent cover whose entire body is a transmissive portion. Therefore, an inner mechanism covered by the cover portion 102 can be visually recognized from the outside. In the present embodiment, a part of a production portion for producing a coffee beverage can be visually recognized through the cover portion 102. The main body portion 101 of the present embodiment is entirely a non-transmissive portion, and it is difficult to visually recognize the inside of the main body portion 101 from the outside.
The housing 100 in a front portion of the beverage production device 1 has a double structure of the main body portion 101 and the cover portion 102 on an outer side (front side) of the main body portion 101. A part of mechanisms of the production portion are disposed between the main body portion 101 and the cover portion 102 in a front-rear direction, and can be visually recognized by a user through the cover portion 102.
A part of the mechanisms of the production portion that can be visually recognized by a user through the cover portion 102 in the present embodiment include a collective conveying portion 42, grinders 5A and 5B, a separation device 6, an extraction container 9, and the like. A rectangular concave portion 101a recessed in a rear side is formed in a front portion of the main body portion 101, and the extraction container 9 and the like are positioned in a rear side of the concave portion 101a.
Since these mechanisms can be visually recognized from the outside through the cover portion 102, an administrator may easily inspect or check the operation. In addition, a beverage consumer may enjoy a process of producing a coffee beverage.
A right end portion of the cover portion 102 is supported by the main body portion 101 via a hinge 102a so as to be freely opened and closed horizontally. An engaging portion 102b is provided at a left end portion of the cover portion 102 to maintain the main body portion 101 and the cover portion 102 in a closed state. The engaging portion 102b is, for example, a combination of a magnet and iron. By opening the cover portion 102, an administrator can inspect a part of the production portion described above on an inner side of the cover portion 102.
Note that in the present embodiment, the cover portion 102 is of a horizontal opening type, but may be of a vertical opening type or a slide type. In addition, the cover portion 102 may be configured such that the cover portion 102 cannot be opened or closed.
The bean processing device 2 produces ground beans from roasted coffee beans. The extraction device 3 extracts a coffee liquid from the ground beans supplied from the bean processing device 2. The extraction device 3 includes a fluid supply unit 7, a drive unit 8, which will be described later, the extraction container 9, and a switching unit 10. The ground beans supplied from the bean processing device 2 are put into the extraction container 9. The fluid supply unit 7 introduces hot water into the extraction container 9. A coffee liquid is extracted from the ground beans in the extraction container 9. The hot water containing the extracted coffee liquid is dispensed into a cup C as a coffee beverage through the switching unit 10.
<2. Fluid Supply Unit and Switching Unit>
Configurations of the fluid supply unit 7 and the switching unit 10 will be described with reference to
The fluid supply unit 7 includes pipes L1 to L3. The pipe L1 is a pipe through which air flows, and the pipe L2 is a pipe through which water flows. The pipe L3 is a pipe through which both air and water can flow.
The fluid supply unit 7 includes a compressor 70 as a pressure source. The compressor 70 compresses and sends out the air. The compressor 70 is driven by, for example, a motor (not shown) as a drive source. The compressed air sent out from the compressor 70 is supplied to a reserve tank (accumulator) 71 via a check valve 71a. An atmosphere pressure in the reserve tank 71 is monitored by a pressure sensor 71b, and the compressor 70 is driven such that the atmosphere pressure is maintained at a predetermined atmosphere pressure (7 atm (6 atm in gauge pressure) in the present embodiment). A drain 71c for draining water is provided in the reserve tank 71, and water generated by the compression of air can be drained.
Hot water (water) constituting a coffee beverage is stored in a water tank 72. The water tank 72 is provided with a heater 72a for heating the water in the water tank 72 and a temperature sensor 72b for measuring a temperature of the water. The heater 72a maintains a temperature of the accumulated hot water at a predetermined temperature (120° C. in the present embodiment) based on a detection result of the temperature sensor 72b. For example, the heater 72a is turned on when the temperature of the hot water is 118° C., and is turned off when the temperature of the hot water is 120° C.
The water tank 72 is also provided with a water level sensor 72c. The water level sensor 72c detects a water level of the hot water in the water tank 72. When the water level sensor 72c detects that the water level is lower than a predetermined water level, water is supplied to the water tank 72. In the present embodiment, water is supplied via a water purifier (not shown). An electromagnetic valve 72d is provided in the middle of the pipe L2 from the water purifier, and when a decrease in the water level is detected by the water level sensor 72c, the electromagnetic valve 72d is opened to supply water, and when the water level reaches a predetermined water level, the electromagnetic valve 72d is closed to cut off the supply of water. In this way, the hot water in the water tank 72 is maintained at a constant water level. The water may be supplied to the water tank 72 every time the hot water used for producing one coffee beverage is discharged.
The water tank 72 is also provided with a pressure sensor 72g. The pressure sensor 72g detects an atmospheric pressure in the water tank 72. The atmosphere pressure in the reserve tank 71 is supplied to the water tank 72 via a pressure regulating valve 72e and an electromagnetic valve 72f. The pressure regulating valve 72e reduces the atmosphere pressure supplied from the reserve tank 71 to a predetermined atmosphere pressure. In the present embodiment, the atmosphere pressure is reduced to 3 atm (2 atm in gauge pressure). The electromagnetic valve 72f switches between supplying to the water tank 72 and cutting off the atmosphere pressure regulated by the pressure regulating valve 72e. The electromagnetic valve 72f is controlled to open and close so that the atmosphere pressure in the water tank 72 is maintained at 3 atm except when the water is supplied to the water tank 72. When the water is supplied to the water tank 72, the atmosphere pressure in the water tank 72 is reduced to a pressure lower than a water pressure of the tap water (for example, less than 2.5 atm) by an electromagnetic valve 72h so that the water is smoothly supplied to the water tank 72 by the water pressure of the water. The electromagnetic valve 72h switches whether to open the water tank 72 to the atmosphere, and opens the water tank 72 to the atmosphere during pressure reduction. In addition, the electromagnetic valve 72h opens the water tank 72 to the atmosphere when the atmosphere pressure in the water tank 72 exceeds 3 atm and maintains the inside of the water tank 72 at 3 atm, except when the water is supplied to the water tank 72.
The hot water in the water tank 72 is supplied to the extraction container 9 via a check valve 72j, an electromagnetic valve 72i, and the pipe L3. The hot water is supplied to the extraction container 9 by opening the electromagnetic valve 72i, and the supply of the hot water is cut off by closing the electromagnetic valve 72i. An amount of the hot water to be supplied to the extraction container 9 can be controlled by an open time of the electromagnetic valve 72i. However, the opening and closing of the electromagnetic valve 72i may be controlled by measuring the supply amount. A temperature sensor 73e for measuring a temperature of the hot water is provided in the pipe L3, and the temperature of the hot water supplied to the extraction container 9 is monitored.
The atmospheric pressure of the reserve tank 71 is also supplied to the extraction container 9 via a pressure regulating valve 73a and an electromagnetic valve 73b. The pressure regulating valve 73a reduces the atmospheric pressure supplied from the reserve tank 71 to a predetermined atmospheric pressure. In the present embodiment, the atmosphere pressure can be reduced to 5 atm (4 atm in gauge pressure). The electromagnetic valve 73b switches between supplying to the extraction container 9 and cutting off the atmospheric pressure regulated by the pressure regulating valve 73a. The atmospheric pressure in the extraction container 9 is detected by a pressure sensor 73d. When the extraction container 9 is pressurized, the electromagnetic valve 73b is opened based on a detection result of the pressure sensor 73d, and the inside of the extraction container 9 is pressurized to a predetermined atmospheric pressure (in the present embodiment, a maximum of 5 atm (4 atm in gauge pressure)). The atmospheric pressure in the extraction container 9 can be reduced by an electromagnetic valve 73c. The electromagnetic valve 73c switches whether to open the extraction container 9 to the atmosphere, and opens the extraction container 9 to the atmosphere when the pressure is abnormal (for example, when the inside of the extraction container 9 exceeds 5 atm).
In the present embodiment, when the production of one coffee beverage is completed, the inside of the extraction container 9 is washed with water. An electromagnetic valve 73f is opened at the time of washing, and supplies the water to the extraction container 9.
Next, the switching unit 10 will be described. The switching unit 10 is a unit that switches a feed-out destination of a liquid fed out from the extraction container 9 to either the pouring portion 10c or a waste tank T. The switching unit 10 includes a switching valve 10a and a motor 10b that drives the switching valve 10a. When a coffee beverage in the extraction container 9 is being fed out, the switching valve 10a switches a flow path to the pouring portion 10c. The coffee beverage is poured into the cup C from the pouring portion 10c. When a waste liquid (water) and residue (ground beans) at the time of washing are to be discharged, the flow path is switched to the waste tank T. In the present embodiment, the switching valve 10a is a three-port ball valve. Since the residue passes through the switching valve 10a at the time of washing, the switching valve 10a is preferably a ball valve, and the motor 10b switches the flow path by rotating a rotation shaft thereof.
<3. Bean Processing Device>
The bean processing device 2 will be described with reference to
<3-1. Reservoir Device>
The reservoir device 4 includes the plurality of canisters 40 in which roasted coffee beans are accommodated. In the present embodiment, three canisters 40 are provided. Each of the canisters 40 includes a cylindrical main body 40a for accommodating roasted coffee beans, and a handle 40b provided on the main body 40a, and is configured to be detachably attached to the beverage production device 1.
Each of the canisters 40 may accommodate different types of roasted coffee beans, and may be configured such that a type of roasted coffee beans used for producing a coffee beverage can be selected according to an operation input to the information display device 12. The roasted coffee beans of different types are, for example, roasted coffee beans of different coffee bean varieties. The roasted coffee beans of different types are coffee beans of the same type, but may be roasted coffee beans of different degrees of roasting. The roasted coffee beans of different types may be roasted coffee beans of different varieties and degrees of roasting. In addition, roasted coffee beans in which roasted coffee beans of a plurality of types and varieties are mixed may be accommodated in at least one of the three canisters 40. In this case, roasted coffee beans of each variety may have the same degree of roasting.
Although a plurality of canisters 40 are provided in the present embodiment, only one canister 40 may be provided. When a plurality of canisters 40 are provided, roasted coffee beans of the same type may be accommodated in all or a plurality of canisters 40.
Each of the canisters 40 is detachably attached to a weighing conveying device 41. The weighing conveying device 41 is, for example, an electric screw conveyor, and automatically measures a predetermined amount of roasted coffee beans accommodated in the canister 40 and feeds out the roasted coffee beans to a downstream side.
Each weighing conveying device 41 discharges the roasted coffee beans to the collective conveying portion 42 on the downstream side. The collective conveying portion 42 is formed of a hollow member, and forms a conveying passage for roasted coffee beans from each of the conveyors 41 to the pulverizing device 5 (in particular, the grinder 5A). The roasted coffee beans discharged from each weighing conveying device 41 move inside the collective conveying portion 42 by an own weight thereof, and flow down to the pulverizing device 5.
A guide portion 42a is formed in the collective conveying portion 42 at a position corresponding to the bean inlet 103. The guide portion 42a forms a passage for guiding roasted coffee beans put from the bean inlet 103 to the pulverizing device 5 (in particular, the grinder 5A). As a result, in addition to the roasted coffee beans accommodated in the canister 40, a coffee beverage made from roasted coffee beans put from the bean inlet 103 can be produced.
<3-2. Pulverizing Device>
The pulverizing device 5 will be described with reference to
The grinders 5A and 5B have different particle sizes for grinding beans. The grinder 5A is a grinder for coarse grinding, and the grinder 5B is a grinder for fine grinding. The grinders 5A and 5B are electric grinders, and include a motor as a drive source, a rotary blade driven by the motor, and the like. A size (particle size) of roasted coffee beans to be ground can be changed by changing the number of rotations of the rotary blade.
The separation device 6 is a mechanism for separating wastes from ground beans. The separation device 6 includes a passage portion 63a disposed between the grinder 5A and the grinder 5B. The passage portion 63a is a hollow body that forms a separation chamber through which ground beans falling freely from the grinder 5A pass. A passage portion 63b extending in a direction (in the present embodiment, a left-right direction) intersecting a passing direction (in the present embodiment, the upper-lower direction) of the ground beans is connected to the passage portion 63a, and a suction unit 60 is connected to the passage portion 63b. By the suction unit 60 suctioning the air in the passage portion 63a, lightweight objects such as chaff and fine powder are suctioned. As a result, the wastes can be separated from the ground beans.
The suction unit 60 is a mechanism of a centrifugal separation type. The suction unit 60 includes an air blowing unit 60A and a collection container 60B. The air blowing unit 60A in the present embodiment is a fan motor, and exhausts the air in the collection container 60B upward.
The collection container 60B includes the upper portion 61 and the lower portion 62 that are engaged with each other in a separable manner. The lower portion 62 has a bottomed cylindrical shape with an open upper side, and forms a space for accumulating wastes. The upper portion 61 constitutes a lid portion to be attached to an opening of the lower portion 62. The upper portion 61 includes a cylindrical outer circumferential wall 61a and an exhaust pipe 61b formed coaxially with the outer circumferential wall 61a. The air blowing unit 60A is fixed to the upper portion 61 above the exhaust pipe 61b so as to suction the air in the exhaust pipe 61b. The passage portion 63b is connected to the upper portion 61. The passage portion 63b is open to the side of the exhaust pipe 61b.
As the air blowing unit 60A is driven, air flows indicated by arrows dl to d3 in
The plurality of fins 61d are integrally formed on a circumferential surface of the exhaust pipe 61b. The plurality of fins 61d are disposed in a circumferential direction of the exhaust pipe 61b. Each of the fins 61d is inclined obliquely with respect to an axial direction of the exhaust pipe 61b. The provision of such fins 61 facilitates the swirling of the air containing the waste D around the exhaust pipe 61b.
The lower portion 62 in the present embodiment is made of a translucent material such as acrylic or glass, and constitutes a transparent container whose entire body is a transmissive portion. The lower portion 62 is a portion covered by the cover portion 102 (
As described above, in the first embodiment, roasted coffee beans supplied from the reservoir device 4 are first coarsely ground by the grinder 5A, and wastes are separated by the separation device 6 when the coarsely ground beans pass through the passage portion 63a. The coarsely ground beans from which the waste is separated are finely ground by the grinder 5B. The waste to be separated by the separation device 6 are typically chaff and fine powder. These may impair the taste of a coffee beverage, and the quality of the coffee beverage can be improved by removing chaff and the like from ground beans.
Roasted coffee beans may be pulverized by one grinder (one-stage pulverizing). However, as in the present embodiment, performing two-stage pulverizing by the two grinders 5A and 5B makes it easier for ground beans to have a uniform particle size and makes it possible to have a constant degree of extraction of a coffee liquid. At the time of pulverization of beans, heat may be generated due to friction between a cutter and the beans. By performing two-stage pulverizing, heat generation due to friction during pulverizing can be prevented, and deterioration of ground beans (for example, deterioration of flavor) can be prevented.
Through steps of coarse grinding, separation of wastes, and fine grinding, it is possible to increase a mass difference between the wastes such as chaff and ground beans (necessary part) when the wastes are separated. This makes it possible to improve a separation efficiency of wastes, and to prevent ground beans (necessary part) from being separated as wastes. In addition, since a waste separation process using air aspiration is interposed between the coarse grinding and the fine grinding, heat generation of ground beans can be prevented by air cooling.

Although the operation unit 81C is also configured to be capable of opening and closing the lid unit 91, in the present embodiment, the operation unit 81C is not used to open and close the lid unit 91.
Hereinafter, although the description of the operation unit 81C is substantially the same as the description of the operation unit 81A, the operation unit 81C will be described below. The operation unit 81C includes a support member 810, a holding member 811, a lifting and lowering shaft 812, and a probe 813.
The support member 810 is fixed such that a relative position with respect to the frame F does not change, and accommodates the holding member 811. The support member 810 also includes a communication portion 810a that allows the switching valve 10a of the switching unit 10 to communicate with the inside of the support member 810. Residues of a coffee beverage, water, and ground beans in the container main body 90 are introduced into the switching valve 10a via the communication portion 810a.
The holding member 811 has a cylindrical space into which the convex portion 911d of the lid unit 91 or the convex portion 901c of the bottom member 901 is inserted, and includes a mechanism that detachably holds the convex portion 911d and the convex portion 901c. The mechanism is, for example, a snap ring mechanism, and is engaged by a constant pressing force, and is disengaged by a constant separating force. Residues of a coffee beverage, water, and ground beans in the container main body 90 are introduced into the switching valve 10a via the communication portion 810a and a communication hole 811a of the holding member 811.
The holding member 811 is also a movable member provided slidably in the upper-lower direction in the support member 810. The lifting and lowering shaft 812 is provided such that its axial direction is in the upper-lower direction. The lifting and lowering shaft 812 airtightly penetrates a bottom portion of the support member 800 in the upper-lower direction, and is provided so as to be vertically lifted and lowered with respect to the support member 810.
A bottom portion of the holding member 811 is fixed to a lower end portion of the lifting and lowering shaft 812. By the lifting and lowering of the lifting and lowering shaft 812, the holding member 811 slides in the upper-lower direction, and the holding member 811 can be attached to and separated from the convex portion 901c and the convex portion 911d.
A screw 812a constituting a lead screw mechanism is formed on an outer circumferential surface of the lifting and lowering shaft 812. A nut 814b is screwed to the screw 812a. The lower unit 8C includes a motor 814a, and the nut 814b is rotated on the spot by a driving force of the motor 814a (without moving up and down). The lifting and lowering shaft 812 is lifted and lowered by the rotation of the nut 814b.
The lifting and lowering shaft 812 is a tubular shaft having a through hole in its central axis, and the probe 813 is inserted into the through hole in a vertically slidable manner. The probe 813 airtightly penetrates the bottom portion of the holding member 811 in the upper-lower direction, and is provided so as to be vertically lifted and lowered with respect to the support member 810 and the holding member 811.
The probe 813 is an operator that opens and closes the valves 913 and 903 provided inside the convex portions 911d and 901c, and the valves 913 and 903 can be changed from the closed state to the open state by lifting the probe 813, and can be changed from the open state to the closed state (due to the action of a return spring (not shown)) by lowering the probe 813.
A screw 813a constituting a lead screw mechanism is formed on an outer circumferential surface of the probe 813. A nut 815b is screwed to the screw 813a. The lower unit 8C includes a motor 815a, and the nut 815b is provided so as to rotate on the spot by a driving force of the motor 815a (without moving up and down). The probe 813 is lifted and lowered by the rotation of the nut 815b.
<4-4. Middle Unit>
The middle unit 8B will be described with reference to
The lock mechanism 821 is a mechanism for maintaining the lid unit 91 in a closed state with respect to the container main body 90. The lock mechanism 821 includes a pair of gripping members 821a that vertically sandwich the flange portion 911c of the lid unit 91 and the flange portion 90c of the container main body 90. The pair of gripping members 821a have a C-shaped cross section in which the flange portion 911c and the flange portion 90c are sandwiched therebetween and fitted to each other, and are opened and closed in the left-right direction by a driving force of a motor 822. When the pair of gripping members 821a are in a closed state, the gripping members 821a are fitted into the flange portion 911c and the flange portion 90c so as to vertically sandwich the flange portion 911c and the flange portion 90c, and the lid unit 91 is airtightly locked with respect to the container main body 90, as indicated by a solid line in an enclosing diagram of
When the pair of gripping members 821a are in an open state, the gripping members 821a are separated from the flange portion 911c and the flange portion 90c, and the lid unit 91 and the container main body 90 are unlocked, as indicated by a broken line in the enclosing diagram of
In a case where the holding member 801 holds the lid unit 91 and the holding member 801 is lifted from a lowered position to a lifted position, the lid unit 91 is separated from the container main body 90 when the pair of gripping members 821a are in the open state. Conversely, when the pair of gripping members 821a are in the closed state, the holding member 801 is released from the lid unit 91, and only the holding member 801 is lifted.
The middle unit 8B also includes a mechanism that horizontally moves the arm member 820 in the front-rear direction using a motor 823 as a drive source. As a result, the container main body 90 supported by the arm member 820 can be moved between a rear-side extraction position (state ST1) and a front-side bean input position (state ST2). The bean input position is a position at which ground beans are put into the container main body 90, and ground beans ground by the grinder 5B are put into the opening 90a of the container main body 90 from which the lid unit 91 is separated, from the discharge pipe 5C. In other words, a position of the discharge pipe 5C is above the container main body 90 positioned at the bean input position.
The extraction position is a position at which the container main body 90 can be operated by the operation unit 81A and the operation unit 81C, is a position coaxial with the probes 803 and 813, and is a position at which a coffee liquid is extracted. The extraction position is a position on the rear side of the bean input position.
The middle unit 8B also includes a mechanism that rotates the support unit 81B about a shaft 825 in the front-rear direction using a motor 824 as a drive source. Accordingly, it is possible to change a posture of the container main body 90 (the extraction container 9) from an upright posture (state ST1) in which the neck portion 90b is on an upper side to an inverted posture (state ST3) in which the neck portion 90b is on a lower side. During the rotation of the extraction container 9, the lock mechanism 821 maintains a state in which the lid unit 91 is locked to the container main body 90. The extraction container 9 is turned upside down between the upright posture and the inverted posture. In the inverted posture, the convex portion 911d is positioned at the position of the convex portion 901c in the upright posture. In the inverted posture, the convex portion 901c is positioned at the position of the convex portion 911d in the upright posture. Therefore, in the inverted posture, the opening and closing operation with respect to the valve 903 can be performed by the operation unit 81A, and the opening and closing operation with respect to the valve 913 can be performed by the operation unit 81C.
<5. Control Device>
A control device 11 of the beverage production device 1 will be described with reference to
The control device 11 controls the entire beverage production device 1. The control device 11 includes a processing unit 11a, a storage unit 11b, and an interface (I/F) unit 11c. The processing unit 11a is, for example, a processor such as a CPU. The storage unit 11b is, for example, a RAM or a ROM. The I/F unit 11c includes an input and output interface that inputs and outputs a signal between an external device and the processing unit 11a. The I/F unit 11c also includes a communication interface capable of performing data communication with a server 16 and a mobile terminal 17 via a communication network 15 such as the Internet. The server 16 can communicate with a mobile terminal 17 such as a smartphone via the communication network 15, and can receive, for example, information such as a reservation for beverage production or an impression from the mobile terminal 17 of a beverage consumer. A system for extracting a coffee beverage liquid from an extraction target includes the beverage production device 1, the server 16, and the mobile terminal 17.
The processing unit 11a executes a program stored in the storage unit 11b, and controls an actuator group 14 based on an instruction from the information display device 12, a detection result of a sensor group 13, or an instruction from the server 16. The sensor group 13 includes various sensors (for example, a hot water temperature sensor, an operation position detection sensor of a mechanism, a pressure sensor) provided in the beverage production device 1. The actuator group 14 includes various actuators (for example, a motor, an electromagnetic valve, a heater, and the like) provided in the beverage production device 1.
A beverage consumer (user) can set a profile for beverage production from the portable terminal 17. For example, on a screen of the mobile terminal 17, the user can set the amount of coffee beans, the grind size, the amount of steaming hot water, a steaming time, the amount of hot water to be extracted, an extraction pressure, an extraction time, and the like, using a slide bar, for example. By enabling parameter adjustment for coffee beverage extraction on the mobile terminal 17, the user may be able to easily enjoy the feeling of coffee extraction operation like a barista. After the setting, the user visits a cafe for example, and holds a two-dimensional code representing the setting content displayed on the screen of the mobile terminal 17 over an imaging unit of the information display device 12, so as to send the setting content to the information display device 12. The setting content may be sent to the information display device 12 by other methods than the two-dimensional code, and for example, the setting content may be sent to the information display device 12 by short-range wireless communication. Note that in the present embodiment, the above parameters for extracting a coffee beverage are referred to as an extraction profile or a recipe.
<6. Operation Control Example>
A control process example of the beverage production device 1 executed by the processing unit 11a will be described with reference to (A) and (B) of
The extraction device 3 is in the state of
When there is a coffee beverage production instruction in the standby state, a process of (A) of
The electromagnetic valve 72i is opened for a predetermined time (for example, 1500 milliseconds) and then closed. Thereby, hot water is poured into the extraction container 9 from the water tank 72. Next, the electromagnetic valve 73 is opened for a predetermined time (for example, 500 milliseconds) and then closed. Thereby, the air in the extraction container 9 is pressurized, and the discharge of hot water to the waste tank T is facilitated. Through the above process, the inside of the extraction container 9 and the pipe L2 are preheated, and hot water can be less cooled in the subsequent production of a coffee beverage.
In S2, a grinding process is performed. Here, roasted coffee beans are pulverized, and the ground beans are put into the container main body 90. First, the lock mechanism 821 is opened to lift the holding member 801 to the lifted position. The lid unit 91 is held by the holding member 801 and is lifted together with the holding member 801. As a result, the lid unit 91 is separated from the container main body 90. The holding member 811 is lowered to the lowered position. The container main body 90 is moved to the bean input position. Next, the reservoir device 4 and the pulverizing device 5 are operated. Thus, one cup of roasted coffee beans is supplied from the reservoir device 4 to the grinder 5A. The roasted coffee beans are ground in two stages by the grinder 5A and the grinder 5B, and wastes are separated by the separation device 6. The ground beans are put into the container main body 90.
The container main body 90 is returned to the extraction position. The holding member 801 is lowered to the lowered position, and the lid unit 91 is attached to the container main body 90. The lock mechanism 821 is in a closed state, and the lid unit 91 is airtightly locked to the container main body 90. The holding member 811 is lifted to the lifted position. In the valves 903 and 913, the valve 903 is in the open state, and the valve 913 is in the closed state.
In S3, an extraction process is performed. Here, a coffee liquid is extracted from the ground beans in the container main body 90. (B) of
In S11, in order to steam the ground beans in the extraction container 9, hot water in an amount less than one cup is poured into the extraction container 9. Here, the electromagnetic valve 72i is opened for a predetermined time (for example, 500 milliseconds) and then closed. Thereby, hot water is poured into the extraction container 9 from the water tank 72. Thereafter, the process of S11 ends after waiting for a predetermined time (for example, 5000 milliseconds). By this process, the ground beans can be steamed. By steaming the ground beans, carbon dioxide gas contained in the ground beans can be released, and a subsequent extraction effect can be enhanced.
In S12, hot water is poured into the extraction container 9 in an amount to add up to one cup of hot water so that the extraction container 9 accommodates one cup of hot water. Here, the electromagnetic valve 72i is opened for a predetermined time (for example, 7000 milliseconds) and then closed. Thereby, hot water is poured into the extraction container 9 from the water tank 72.
By the process of S12, the inside of the extraction container 9 can be brought into a state of a temperature exceeding 100° C. at 1 atm (for example, about 110° C.). Next, the inside of the extraction container 9 is pressurized in S13. Here, the electromagnetic valve 73b is opened for a predetermined time (for example, 1000 milliseconds) and then closed, and the inside of the extraction container 9 is pressurized to an atmospheric pressure at which hot water does not boil (for example, about 4 atm (about 3 atm in gauge pressure)). Thereafter, the valve 903 is brought into the closed state.
Next, this state is maintained for a predetermined time (for example, 7000 milliseconds) to perform immersion-type coffee liquid extraction (S14). As a result, immersion-type coffee liquid extraction is performed under a high temperature and high pressure. In the immersion-type extraction under a high temperature and high pressure, the following effects can be expected. First, by setting a high pressure, hot water can be easily permeated into the ground beans, and extraction of a coffee liquid can be facilitated. Second, by setting a high temperature, the extraction of the coffee liquid is facilitated. Third, by setting a high temperature, the viscosity of an oil contained in the ground beans decreases, and the extraction of the oil is facilitated. As a result, a coffee beverage with high aroma can be produced.
A temperature of hot water (high temperature water) may be higher than 100° C., but a higher temperature is more advantageous in terms of the extraction of the coffee liquid. On the other hand, increasing the temperature of the hot water generally results in an increase in cost. Therefore, the temperature of the hot water may be, for example, 105° C. or more, or 110° C. or more, or 115° C. or more, and may be, for example, 130° C. or less, or 120° C. or less. The atmospheric pressure may be any atmospheric pressure at which the hot water does not boil.
In S15, the inside of the extraction container 9 is depressurized. Here, the atmospheric pressure in the extraction container 9 is switched to an atmospheric pressure at which the hot water boils. Specifically, the valve 913 is brought into the open state, and the electromagnetic valve 73c is opened for a predetermined time (for example, 1000 milliseconds) and then closed. The inside of the extraction container 9 is open to the atmosphere. Thereafter, the valve 913 is brought into the closed state again.
The inside of the extraction container 9 is rapidly depressurized to an atmospheric pressure lower than the boiling point pressure, and the hot water in the extraction container 9 boils at once. The hot water and ground beans in the extraction container 9 are explosively scattered in the extraction container 9. As a result, the hot water can evenly boil. The destruction of cell walls of the ground beans can be facilitated, and the subsequent extraction of the coffee liquid can be further facilitated. In addition, since the ground beans and the hot water can be stirred by this boiling, the extraction of the coffee liquid can be facilitated. In this way, in the present embodiment, the extraction efficiency of the coffee liquid can be improved.
In S16, the extraction container 9 is inverted from the upright posture to the inverted posture. Here, the holding member 801 is moved to the lifted position and the holding member 811 is moved to the lowered position. Then, the support unit 81B is rotated. Thereafter, the holding member 801 is returned to the lowered position, and the holding member 811 is returned to the lifted position. In the extraction container 9 in the inverted posture, the neck portion 90b and the lid unit 91 are positioned on the lower side.
In S17, permeation-type coffee liquid extraction is performed, and a coffee beverage is dispensed into the cup C. Here, the switching valve 10a is switched to allow the pouring portion 10c and the passage portion 810a of the operation unit 81C to communicate with each other. Both the valves 903 and 913 are brought into the open state. Further, the electromagnetic valve 73b is opened for a predetermined time (for example, 10000 milliseconds), and the inside of the extraction container 9 is set to a predetermined atmospheric pressure (for example, 1.7 atm (0.7 atm in gauge pressure)). In the extraction container 9, a coffee beverage in which the coffee liquid is dissolved in the hot water passes through a filter provided in the lid unit 91 and is dispensed into the cup C. The filter regulates the leakage of a residue of the ground beans. Thus, the extraction process ends.
In the present embodiment, the extraction efficiency of the coffee liquid can be improved by using the immersion-type extraction in S14 and the permeation-type extraction in S17 in combination. When the extraction container 9 is in the upright posture, the ground beans accumulate from the body portion 90e to the bottom portion 90f. On the other hand, when the extraction container 9 is in the inverted posture, the ground beans accumulate from the shoulder portion 90d to the neck portion 90b. A cross-sectional area of the body portion 90e is larger than a cross-sectional area of the neck portion 90b, and a deposition thickness of the ground beans in the inverted posture is larger than a deposition thickness in the upright posture. That is, the ground beans accumulate relatively thinly and widely when the extraction container 9 is in the upright posture, and accumulate relatively thickly and narrowly when the extraction container 9 is in the inverted posture.
In the present embodiment, since the immersion-type extraction in S14 is performed when the extraction container 9 is in the upright posture, the hot water and the ground beans can be brought into contact over a wide range, and the extraction efficiency of the coffee liquid can be improved. However, in this case, the hot water and the ground beans tend to partially come into contact with each other. On the other hand, since the permeation-type extraction in S17 is performed when the extraction container 9 is in the inverted posture, the hot water passes through the accumulated ground beans while being in contact with more of the ground beans. The hot water comes into contact with the ground beans more evenly, and the extraction efficiency of the coffee liquid can be further improved.
Returning to (A) of
Thus, one coffee beverage production process is completed. Thereafter, the same process is repeated for each production instruction. The time required for producing one coffee beverage is, for example, about 60 seconds to 90 seconds.
<7. Display Control Example>
Display control process during the production of the coffee beverage according to the present embodiment will be described below. In the present embodiment, an image during production selected by the user is displayed on the information display device 12 during production of a coffee beverage corresponding to a recipe. For example, according to a selection by the user, description of each production step of the coffee beverage is displayed as an image during production while the coffee beverage is being produced. For example, according to a selection by the user, a profile of a recipe creator such as a barista is displayed as the image during production while the coffee beverage is being produced. For example, according to a selection by the user, information of a plantation of the coffee beans used in the selected recipe is displayed as the image during production while the coffee beverage is being produced. It should be noted that the “user” may be a staff member or administrator who provides the coffee beverage using the beverage production device 1, or a general customer who orders the coffee beverage.
In S1201, the processing unit 11a receives recipe selection from the user. The recipe selection may be configured as follows. For example, on the screen displayed on the information display device 12, the recipe selection is displayed as a plurality of selectable items such as “Blend A”, “Blend B”, and the like corresponding to types of coffee beans. In each item, parameters such as the amount of coffee beans, the grind size, the amount of steaming hot water, the steaming time, the amount of hot water to be extracted, the extraction pressure, and the extraction time are linked and stored as a recipe. That is, by selecting any item on the screen, the linked and stored parameters are selected as a recipe. Note that the processing unit 11a may receive the recipe selection on the screen of the information display device 12, or may acquire information on the recipe selected on the mobile terminal 17.
In S1202, the processing unit 11a receives from the user a selection of an image to be displayed during the production of the coffee beverage. After receiving the recipe selection in S1201, the processing unit 11a displays a screen 1810 shown in (B) in
In S1203, the processing unit 11a determines whether to reflect the selection information of the items 1811 to 1814 to the another beverage production device 1. For example, when the item 1815 is selected, the processing unit 11a determines to reflect the selection information of the items 1811 to 1814 to another beverage production device 1, and in S1204, the processing unit 11a sends the selection information of the items 1811 to 1814 to the another beverage production device 1. The another beverage production device 1 that receives the selection information defaults an image to be displayed during the production of the coffee beverage based on the received selection information. After S1204, the process proceeds to S1205. On the other hand, if it is determined not to reflect the selection information of the items 1811 to 1814 to the another beverage production device 1, the process proceeds to S1205.
In S1205, the processing unit 11a determines whether the selected item received in S1202 is recipe information of the item 1813. If it is determined that the selected item received in S1202 is the recipe information of the item 1813, the process proceeds to S1207. On the other hand, if it is determined that the selected item received in S1202 is not the recipe information of the item 1813, the process proceeds to S1206.
In S1206, the processing unit 11a displays a screen 1401 in (A) in
In this way, by displaying the screen 1401 before starting the production of the coffee beverage, it is possible to provide the user with the information about the recipe creator, regardless of the selection made in S1202. After S1206, the process proceeds to S1207.
In S1207, the processing unit 11a waits for a display start timing of the selected image received in S1202. For example, when the preheating process of S1 in (A) in
In S1209, the processing unit 11a ends the image display. For example, the processing unit 11a ends the image display when the discharge process of S4 in (A) in
In S1302, the processing unit 11a displays an image corresponding to the production step. For example, when the process of S1302 is executed for the first time, the processing unit 11a displays a screen 1411 of (B) in
An example in which the tab 1417 is selected is shown in (B) of
If the currently executed production step is “grinding”, a screen 1501 in (A) in
If the currently executed production step is “steaming”, a screen 1511 in (B) in
If the currently executed production step is “main hot water supply”, a screen 1601 in (A) in
If the currently executed production step is “stirring (chamber reversal)”, a screen 1611 in (B) in
If the currently executed production step is “delivery to cup (sending out)”, a screen 1701 in (A) in
The images of the regions 1416, 1503, 1513, 1603, 1613, and 1703 may be, for example, identifiable display of members currently in operation. The image may be a still image, or may be a moving image such as an animation or a video image. Whether the images of the regions 1416, 1503, 1513, 1603, 1613, and 1703 are to be moving images may be selectable on the screen 1810 in (B) in
In S1303, the processing unit 11a determines whether a change of the image to be displayed is received. For example, the processing unit 11a determines whether a tab for displaying an image other than the currently displayed image is selected among the tabs 1417 to 1420. For example, when the screen 1411 in (B) of
In S1304, the processing unit 11a determines whether it is time to switch the image to be displayed, based on whether it is time to switch the production step of the coffee beverage. For example, when the processing unit 11a proceeds from the preheating process of S1 to the grinding process of S2 in (A) of
In S1305, the processing unit 11a determines whether the image displayed before switching is an image corresponding to the last production step. For example, if the image displayed before switching is the screen 1701 in (A) in
If it is determined that the change of the image to be displayed is received in S1303, the processing unit 11a displays the changed image in S1306. For example, when the tab 1418 is pressed while the screen 1501 in (A) in
For example, when the tab 1419 is pressed while the screen 1411 in (B) in
The photo images 1404, 1712, and 1803 described above may be still images, or moving images such as animation or a video image.
In the present embodiment, when the process of S1306 is started, the image after switching is displayed from a time corresponding to elapsed time displayed before switching. For example, when the elapsed time of the screen 1501 displayed before switching is 10 seconds, in S1306, the processing unit 11a displays the screen 1710 from the time when 10 seconds elapses. With such a configuration, the user may be able to check the remaining time of the region 1413 regardless of whether the image is switched. After S1306, the process proceeds to S1308.
In S1308, the processing unit 11a determines whether a change of the image to be displayed is received. For example, the processing unit 11a determines whether a tab for displaying an image other than the currently displayed image is selected among the tabs 1417 to 1420. When the screen 1710 of (B) in
In S1309, the processing unit 11a determines whether it is time to end displaying the image. For example, when the discharge process of S4 in (A) in
S1301 is referred to again. If it is determined in S1301 that the selected image received in S1202 does not need to be switched for each production step of the coffee beverage, the process proceeds to S1307. For example, if selection of any one of the items 1812 to 1814 is received in S1202, it is determined that switching is not necessary for each production step of the coffee beverage, and the process proceeds to S1307. In S1307, the processing unit 11a displays an image corresponding to the selected item received in S1202, for example, the screen 1710 or the screen 1801. After S1307, the process advances to S1308, and the above-described process is performed.
In the above description, although it has been explained that the images in the regions 1416, 1503, 1513, 1603, 1613, and 1703 may be moving images, it is possible to select whether to use moving images on the screen 1810 in (B) of
The display control process according to the present embodiment is described above, but when occurrence of an error related to beverage production is determined internally, an error screen can be displayed, and the user may not be able to select the image during production while the error screen is being displayed. Here, the error means, for example, a cover opening error when opening of the cover portion is detected, and various errors (for example, temperature error and pressure error) when various sensors (for example, the temperature sensor and the pressure sensor) indicate an abnormal value.
In the above, an example of displaying the image during production such as a moving image on the information display device 12 is shown, but the present invention is not limited to displaying one image during production in one display region (display unit), and a plurality of images during production may be configured to be displayed in a plurality of display regions. For example, an image during production “barista image” may be displayed in one display region of the information display device 12, and an image during production “plantation image” may be displayed in another display region of the information display device 12 in parallel, and an image during production “production step image” may be displayed on the cover portion 102.
The screen of the image during production selected by the user is not limited to displaying the name of the image during production (tabs 1417 to 1420) as shown in (B) of
A plurality of images during production may be registered in advance.
As described above, in the present embodiment, it is possible to set a moving image or a still image for each of the six production steps (preheating, grinding, steaming, main hot water supply, stirring, and delivery to cup), and it is also possible to set one image (moving image, still image) for a plurality of production steps. For example, in a period during which a “step 1” (preheating step) is performed when the “barista image” is selected by the user, a “moving image B1” is reproduced, and when switching to a “step 2” (grinding step), the image is also switched from the “moving image B1” to a “moving image B2” and reproduced. On the other hand, in a period from the “step 1” (preheating step) to the “step 2” (grinding step) when the “history image” is selected by the user, a “moving image H2” is reproduced without switching. Note that when one moving image is registered in a certain step, the moving image may be repeatedly reproduced unless another image during production is reselected before the step proceeds to the next step, or a final screen of the moving image may be displayed still.

The row of the image during production pattern may be replaced according to various information stored along with the use of the beverage production device. For example, in the case of the “image during production pattern 1” in (A) in
In the above examples, the default image during production is set, but these examples may be replaced with examples of setting the image during production to be displayed in a certain display region on the user selection screen (for example, the display region where the tab 1417 is displayed among the display regions where the tabs 1417 to 1420 in (B) in
The image during production in the image during production pattern may be added externally (for example, from a server) through a signal line (for example, a LAN line such as the Internet). For example, as a new image during production from the server via the Internet by administrator operation, for example, a “new recipe image” (step 1: moving image N1, step 2: moving image N2, step 6: still image N6) and data of each image (moving image N1, moving image N2, . . . , still image N6) may be downloaded and added to the images during production that can be selected by the user. In this case, to make sure, the “state” field of the newly added image during production may be set to “NO”, and the user may select the image during production only after the “state” is changed from “NO” to “YES” by administrator operation, or the “state” field may be set to “YES” from the beginning. Here, the example of downloading data from the server via the Internet is given, but the present invention is not limited to this, and it is possible to copy or move the image during production and image data stored in other devices such as another beverage production device.
Note that as shown in the image during production pattern, an example in which the image during production that can be selected by the user and image data are stored in the beverage production device and used is shown, but the image during production that can be selected by the user and image data may be stored externally (for example, in a server) and downloaded to the beverage production device via a signal line (for example, the Internet) or wireless communication each time a beverage is extracted or at power-on or each time an image is displayed for the user to choose.
In
In order to make the specific data easier to be displayed, for example, it may be configured to increase the number of times of display or to increase the display time of the specific data compared with other data. In order to increase the number of times of display, for example, in the case of a configuration in which data to be displayed is selected by probability, the configuration may be such that a selection probability thereof is set higher than that of other data. For example, the specific data may also be displayed at a specific timing during the coffee beverage production, such as at the start of any one of the coffee beverage production steps. In
Note that, a plurality of pieces of specific data set according to the type of the coffee beverage may be set as the specific data. In this case, the specific data may be displayed according to the coffee beverage to be produced. The specific data may also be displayed regardless of the type of coffee beverage, and in this case, one piece of data may be set as the specific data, or a plurality of pieces of data may be set.
When there is a plurality of pieces of the specific data, the specific data to be displayed during the production of the next coffee beverage may be determined according to the display time of the specific data during the production of the previous coffee beverage. In
When there is a plurality of pieces of the specific data, the specific data to be displayed during the production of the next coffee beverage may be determined according to the display order of the specific data during the production of the previous coffee beverage. In
With reference to (B) to (D) in
A total display time of the data of the image during production (image data or moving image data) displayed during the production of the coffee beverage may be stored. The number of times the data of the image during production is switched to other data during production (during display) may also be stored. The number of times the data of the image during production is switched from other data during production (during display) may also be stored.
Information regarding the data displayed during the coffee beverage production may be configured to be sent to an external device. With this configuration, it is possible to collect useful information in considering the sales strategy of the product.
In the configuration for making it easier to display the specific data out of the data displayed during the production of the coffee beverage, when this specific data is not displayed, a guidance display may be performed to guide the user to a state in which the specific data is displayed.
In the above example, the beverage production device 1 can be said to be a combination of a device for producing ground beans of coffee and a device for producing a coffee beverage from ground beans. The configuration regarding the display during operation described with reference to
<Summary of Embodiment>
The beverage production device in the above embodiment includes: a production unit for producing a beverage; a display unit (
The selection unit receives a selection of the image during production by a user when the image during production is being displayed by the display unit (S1303, S1308), and when the selection of the image during production made by the user with the selection unit is received, the display unit switches the image during production displayed before the selection is received to the received image during production in the selection (S1302, S1306). With such a configuration, even when the image during production is being displayed, it is possible to switch to the selected image during production and display it.
The display unit displays the image during production after the switching from a time point corresponding to a display elapsed time of the image during production before the switching. With such a configuration, it is possible to display the image during production after the switching from a time point corresponding to the display elapsed time of the image during production before the switching.
