<First Embodiment>
FIG. 1 is a diagram showing a schematic configuration of a roasting system 100 according to the first embodiment of the present invention.

  The roasting system 100 of the first embodiment includes a server computer 10, a communication network 20, a terminal 30, and a roasting machine 40, as shown in FIG.

  The server computer 10 includes a database (storage means) 11 for storing roasting operation data 111 corresponding to the temperature of the coffee beans and ideal temperature change data 112 indicating ideal temperature changes of the coffee beans in the roasting process.

  The roasting operation data 111 includes the number of gas burners of the roasting machine 40 to be described later, the gas pressure of the gas burner, and the roasting temperature according to the roasting temperature of coffee beans (hereinafter referred to as “product temperature” as necessary) It is the data which shows the ventilation volume to the roaster. The ideal temperature change data 112 is data indicating the ideal temperature change of the coffee beans over time when the operator performs a roasting operation based on the roasting operation data 111. FIG. 1 schematically shows an example of roasting work data 111 and ideal temperature change data 112 in a table.

  The roasting work data 111 and the ideal temperature change data 112 are stored in the database 11 for each type of coffee bean or for each type of roasting machine. In order to produce roasted coffee beans having different flavors, a plurality of different roasting operation data 111 and ideal temperature change data 112 are stored in a database in the same type of coffee beans and the same roaster. Also good.

  The communication network 20 is a network such as a WAN or a LAN, and connects the server computer 10 and the terminal 30 to enable mutual data transmission / reception.

  As shown in FIG. 2, the terminal 30 includes a CPU (central processing unit) 301 including a microprocessor, a ROM 302, a RAM 303, an HDD 304, a display unit 305, an input unit 306, and an interface that are bus-coupled to the CPU 301. 307 and the like.

  Functionally, the terminal 30 includes a data acquisition unit 31 and a presentation unit 32 as shown in FIG. Each of these means is realized mainly by the CPU 301 executing a program stored in the ROM 302 or the RAM 303 and controlling each hardware.

  The data acquisition means 31 acquires roasting operation data 111 and ideal temperature change data 112 stored in the database 11 from the server computer 10 and roasting temperature data 113 (described later) transmitted by the transmission means 43 of the roaster 40. Is something to get.

  The presenting means 32 presents the roasting operation data 111 to the operator, and further presents the change of the roasting temperature data 113 together with the ideal temperature change data 112 to the operator. For example, the presentation unit 32 displays the roasting work data 111 and the ideal temperature change data 112 on the display (display unit) and presents them to the operator. The presenting means 32 is not limited to displaying data on the display, but may display each data on an operator by printing the data on a printing device connected via the interface 307, for example.

  The roasting machine 40 is a machine for roasting coffee beans as shown in FIG. 3, and is housed in a roasting room storage section 50 as an internal configuration thereof as schematically shown in FIG. The roasting chamber 51 and the roasting chamber storage section 50 are supplied with air to the roasting chamber storage section 50 through a heater 52 having three gas burners for heating the roasting chamber 51, a pipe 53 and a valve 54. A blower 55 for blowing air, a temperature sensor 56 disposed in the roasting chamber 51, a transmission unit 57 connected to the temperature sensor 56, and the like are provided. The temperature sensor 56 is preferably arranged so as to directly touch the coffee beans so that the roasting temperature of the coffee beans can be accurately detected.

  The roasting machine 40 functionally includes a setting unit 41, a temperature detection unit 42, a transmission unit 43, and the like as shown in FIG.

  The setting means 41 sets at least one of the heating amount of the coffee beans and the blowing amount into the roasting chamber by the operation of the operator, and is realized by an electrical processing circuit or mechanically. For example, the setting means 41 sets the heating amount of the coffee beans by adjusting at least one of the number of gas burners to be ignited and the gas pressure of the gas burner, and the amount of air blown into the roasting chamber 51 is roasted. It is set by adjusting the number of rotations of the blower 55 that blows air into the chamber 51. These can be set, for example, based on an operator's operation on the gas pressure adjustment handle 401 and the temperature regulator 402 shown in FIG. Note that the roasting machine 40 can discharge the air blown from the blower 55 to the outside air through an exhaust pipe (not shown) separately provided in the roasting chamber storage unit 50.

  The temperature detection means 42 detects the roasting temperature of coffee beans roasted in the roasting chamber 51 and is realized by using a temperature sensor 56. The roasting temperature data (roasting temperature data) detected by the temperature detecting means 42 is sent to the transmitting means 43. Further, the roasting temperature detected by the temperature detecting means 42 can be displayed on a temperature display attached to the temperature regulator 402, for example.

  The transmission unit 43 transmits the roasting temperature data detected by the temperature detection unit 42 to the terminal 30 over time (in real time), and is realized by using the transmission unit 57. The transmission unit 43 transmits data by connecting to the interface 307 of the terminal 30 via a communication cable (for example, a USB cable). Note that the transmission unit 43 may transmit data to the terminal 30 by wireless communication instead of via a communication cable.

  Hereinafter, the roasting method performed using the roasting system 100 will be described with reference to the flowchart shown in FIG.

  First, as a pre-processing stage of the roasting work stage, the server computer 10 stores a plurality of roasting work data 111 and ideal temperature change data 112 in the database 11 by a user operation on the server side (S100). As the roasting operation data 111 and the ideal temperature change data 112 to be stored, for example, data created in advance by an engineer who has a high roasting technology related to coffee beans can be used. The server computer 10 can also receive data transmitted from other terminals connected via the communication network 20 and store the received data in the database 11.

  In the roasting operation stage, the data acquisition means 31 acquires the roasting operation data 111 and the ideal temperature change data 112 stored in the database 11 from the server computer 10 (S101). For example, the data acquisition means 31 is selected from among a plurality of roasting work data 111 and ideal temperature change data 112 stored in the database 11 in the server computer 10 by an operator's operation from the input unit 306 or by an automatic connection program or the like. The operator requests and obtains roasting operation data 111 and ideal temperature change data 112 according to the type of coffee beans to be roasted and the type of roasting machine to be used. Note that the data acquisition unit 31 may acquire not only each data required by the operator but also a plurality of data stored in the database 11 by the server computer 10 at a time.

  Next, the presenting means 32 presents the roasting work data 111 to the operator (S102). As described above, the roasting operation data 111 is data indicating the number of gas burners of the heater 52 according to the product temperature, the gas pressure of the gas burner, and the amount of air blown into the roasting chamber 51, and presenting means 32 displays the roasting work data 111 on the display.

  In step S101, when the data acquisition unit 31 acquires a plurality of pieces of data stored in the database 11 of the server computer 10 at once, roasting operation data required by the operator from the plurality of data is obtained. It may be selected as appropriate by the operation of the operator and displayed on the display.

  The operator can know the amount of heating and the amount of air to be set according to the product temperature by looking at the roasting work data 111 presented on the display, and based on this, the gas pressure adjustment handle 401 and the temperature adjustment can be performed. The device 402 and the like can be operated.

  For example, the gas pressure adjustment handle 401 can be set to 1 to 10 steps (1 is the minimum, 10 is the maximum) in which the magnitude of the gas pressure is increased or decreased step by step, and the temperature regulator 402 is set to the gas burner. Assuming that the number of ignitions and the number of revolutions of the blower 55 can be set, the operator can set the number of gas burners to be 3 when the product temperature is 50 ° C. or less at the start of roasting. The gas pressure adjustment handle 401 and the temperature regulator 402 are operated so that the pressure is in step 8 and the air flow rate is 6 l / s.

  When an operator performs an operation on the gas pressure adjustment handle 401, the temperature regulator 402, or the like, the setting means 41 responds to the number of gas burners of the heater 52, the gas pressure of the gas burner, and the roasting chamber 51. The amount of air blown in is set (S103).

  Next, when the roasting operation is started by the operator and the roasting machine 40 starts the roasting operation, the temperature detecting means 42 detects the roasting temperature of the coffee beans (S104).

  Next, the transmission means 43 transmits the detected roasting temperature data 113 to the terminal 30 over time (in real time) (S105).

  Next, when the data acquisition unit 31 acquires the roasting temperature data 113 transmitted by the transmission unit 43 (S106), the presentation unit 32 displays the change in the acquired roasting temperature data 113 together with the ideal temperature change data 112. (S107). For example, as shown in FIG. 6, the presenting means 32 causes the roasting machine 40 to display the curve indicating the ideal temperature change (ideal temperature change) over time in the roaster 40 over time. The detected actual roasting temperature is plotted and presented to the operator.

  Therefore, during the roasting operation, the operator can see the difference between the ideal temperature and the actual roasting temperature by looking at the graph showing the ideal temperature change and the actual roasting temperature change shown on the display. Since it can be known, the gas pressure adjustment handle 401 and the temperature regulator 402 can be operated in consideration of the roasting work data 111 presented in S102 and the difference.

  For example, during a roasting operation, an operator may perform roasting to match the ideal and actual roasting temperatures over time based on a graph depicting ideal temperature changes and actual roasting temperature changes. In order to finely correct the heating amount and the blowing amount (the number of gas burners of the heater 52, the gas pressure of the gas burner, and the blowing amount into the roasting chamber 51) indicated by the work data 111, The temperature regulator 402 can be operated.

  Next, when an operation is performed by an operator on the gas pressure adjustment handle 401, the temperature regulator 402, etc., the setting means 41 responds to the number of gas burners of the heater 52, the gas pressure of the gas burner, and roasting. The amount of air blown into the chamber 51 is set (S108). During the roasting operation, the roasting system 100 determines whether or not the roasting operation is completed based on the operation of the operator or the passage of time (S109), and determines that the roasting operation is not completed (S109). (S109: No), the processing of the above steps S104 to S108 is repeated, and if it is determined that the roasting operation has ended (S109: Yes), the processing ends.

As described above, according to the roasting system 100 of the first embodiment, the roasting operation can be performed by adjusting the actual roasting temperature of the coffee beans so as to follow an ideal temperature change. The quality of roasted coffee beans can be kept constant.
Second Embodiment
Next, a second embodiment of the present invention will be described in detail.

  Unlike the roasting system 100 of the first embodiment, the roasting system 200 of the second embodiment does not set the heating amount of the coffee beans and the blowing amount to the roasting chamber by the operation of the operator. This is a system that uses a processing circuit built in the roasting machine 40.

  The roasting system 200 according to the second embodiment includes a server computer 10, a communication network 20, a terminal 30 ′, and a roasting machine 40 ′ as shown in FIG. Since the server computer 10 and the communication network 20 in the second embodiment are the same components as those in the first embodiment, the description thereof is omitted.

  On the other hand, the terminal 30 ′ of the roasting system 200 has a point that the interface 307 includes an interface for accessing the removable recording medium 60, and the acquired roasting work data 111 and ideal temperature change as functional means. It differs from the roasting system 100 in that it comprises a recording means 33 for recording the data 112 on the recording medium 60. In the second embodiment, it is not always necessary that the terminal 30 ′ includes the presentation unit 32 and that the data acquisition unit 31 of the terminal 30 ′ acquires the roasting temperature data 113 from the roasting machine 40. . The recording medium 60 may be a recording medium such as a memory card, FD, or CDROM.

  The roasting machine 40 ′ of the roasting system 200 is different from the roasting system 100 in that it includes a processing circuit 44 and an interface 48 for accessing the recording medium 60.

  Since the setting means 41, the temperature detection means 42, and the transmission means 43 are the same as those in the first embodiment, description thereof will be omitted. In addition, it is not necessarily essential to provide the transmission means 43 in 2nd Embodiment.

  The processing circuit 44 includes, for example, a processor for performing various computations and controls, a RAM that temporarily stores data and functions as a working area during computation processing, a ROM that stores programs and data, and a recording medium 50 The peripheral circuit includes an interface 48 for reading data.

  The processing circuit 44 functions as a data input unit 45, a difference comparison unit 46, and a control unit 47 when the processor executes a program stored in the ROM.

  The data input means 45 is means for inputting the roasting work data 111 and the ideal temperature change data 112 held by the terminal 30 ′. When the recording medium 33 on which the recording means 33 of the terminal 30 ′ records the roasting work data 111 and the ideal temperature change data 112 is set in the corresponding interface, the data input means 45 reads the roasting work data 111 from the recording medium 60. And the ideal temperature change data 112 is read.

  The difference comparison means 46 compares the roasting temperature detected by the temperature detection means 42 with the ideal temperature specified by the ideal temperature change data 112 over time, extracts the difference between the two, and the difference is a predetermined value. When the value exceeds, a control command is sent to the control means 47.

  The control means 47 adjusts the setting means 41 based on the roasting work data 111 and the control command transmitted from the difference comparison means 46, and sets the amount of heating of the roasting object and the amount of air blown into the roasting chamber. Control at least one. For example, the control means 47 controls the heating amount of the coffee beans by adjusting the number of gas burners of the heater 52 to be ignited and the gas pressure of the gas burner, and the rotational speed of the blower 55 that blows air into the roasting chamber 51. Is adjusted to control the amount of air blown into the roasting chamber 51.

  Specifically, for example, if the actual roasting temperature is lower than the ideal temperature, the actual roasting temperature is increased by increasing the number of gas burners ignited in the heater 52 or increasing the pressure of the gas burner. And control to match the ideal temperature. Conversely, if the actual roasting temperature is higher than the ideal temperature, the actual roasting temperature is lowered by reducing the number of gas burners ignited by the heater 52 or reducing the pressure of the gas burner 52. Control to match the ideal temperature.

  Hereinafter, the roasting method performed using the roasting system 200 will be described with reference to the flowchart shown in FIG. It is assumed that the recording medium 60 is set in the interface 307 of the terminal 30 ′.

  Since the process of steps S200 and S201 is the same as the process of steps S100 and S101 of the roasting method performed using the roasting system 100, detailed description thereof is omitted.

  After the processes of steps S200 and S201, the recording unit 33 of the terminal 30 ′ records the roasting work data 111 and the ideal temperature change data 112 acquired by the data acquisition unit 31 on the recording medium 60 (S202).

  Next, when the recording medium 60 is taken out from the terminal 30 ′ by the operator and set in the interface 48 of the roasting machine 40 ′, the data input means 45 causes the roasting operation data 111 and ideal temperature held by the terminal 30 ′. In order to input the change data 112, these data 111 and 112 are read from the recording medium 60 (S203).

  Next, when the roasting operation is started by the operator and the roasting machine 40 starts the roasting operation, the temperature detecting means 42 detects the roasting temperature of the roasting object (S204).

  During the roasting operation, the difference comparison means 46 compares the difference between the detected roasting temperature and the ideal temperature specified by the ideal temperature change data, extracts the difference, and the difference exceeds a predetermined value. When this happens, a control command is sent to the control means 47 (S205).

  When the control command transmitted from the difference comparison unit 46 is received, the control unit 47 adjusts the setting unit 41 based on the roasting work data 111 and the received control command, and the heating amount of the roasting target object And at least one of the amount of air blown into the roasting chamber is controlled (S206).

  During the roasting operation, the roasting system 200 determines whether or not the roasting operation has been completed based on the operation of the operator or the passage of time (S207), and when determining that the roasting operation has not been completed (S207). (S207: No), the processing of the above steps S204 to S206 is repeated, and if it is determined that the roasting operation has ended (S207: Yes), the processing ends.

  As described above, according to the roasting system 200 of the second embodiment, the actual roasting temperature of the coffee beans is adjusted so as to follow an ideal temperature change by the processing circuit 44 provided in the roasting machine 40 ′. Since the roasting operation can be performed with adjustment, the quality of the roasted coffee beans can be kept constant.
