本発明は、抄製した海苔生地を乾燥させて乾燥海苔を製造するために建屋の内部に設置された海苔製造機に関するものである。 The present invention relates to a laver making machine installed inside a building in order to dry the produced laver dough and produce dried laver.

従来より、食用に供される乾燥海苔は、水分を多く含んだ海苔生地を矩形シート状に乾燥させることによって製造されており、そのために、建屋の内部に設置された海苔製造機が広く用いられている。 Conventionally, dried laver used for edible purposes has been manufactured by drying a laver dough containing a lot of moisture into a rectangular sheet, and for this reason, laver making machines installed inside buildings are widely used. ing.

この海苔製造機は、スノコ状の海苔簀に海苔生地を抄製するための抄製装置に海苔生地を乾燥させるための乾燥装置を連設し、抄製装置で抄製した海苔生地を海苔簀ごと乾燥装置に受け渡し、乾燥装置によって海苔簀に抄製した海苔生地を乾燥させるようにしている。 This laver making machine is connected to a paper making machine for making a laver dough on a scallop-like seaweed rice cake, and a drying device for drying the seaweed dough is connected continuously. They are handed over to the drying device, and the nori dough made into the laver is dried by the drying device.

また、請求項２に係る本発明では、前記請求項１に係る本発明において、前記コントローラーは、乾燥室の後側部分の湿度が前記第２後側所定湿度よりも高い所定湿度（第１後側所定湿度）よりも高い場合に、後側部分の空気流入量規制装置を制御して乾燥室の排気部から加熱室の後側の吸気部に流入する空気の量を減少させることにした。 Also, in the present invention according to claim 2, in the present invention according to claim 1, the controller has a predetermined humidity (first rear) in which the humidity in the rear portion of the drying chamber is higher than the second predetermined humidity on the second rear side. In the case where the humidity is higher than the predetermined humidity on the side, the amount of air flowing from the exhaust part of the drying chamber to the intake part on the rear side of the heating chamber is reduced by controlling the air inflow control device in the rear part.

そして、本発明では、以下に記載する効果を奏する。 And in this invention, there exists an effect described below.

建屋２の内部に設置された海苔製造機１では、建屋２の内部に乾燥室12の排気部34と加熱室13の吸気部22,30との間に連通状の連通路35が形成される。この連通路35には、乾燥室12の排気部34から加熱室13の吸気部22,30へと流入する空気の流入量を規制するための４個の空気流入量規制装置36〜39を前後に並べて配置している。このうち、前側の２個の空気流入量規制装置36,37は、前側の加熱装置16と対応する位置（後側の加熱装置17の吸気部30よりも前側の加熱装置16の吸気部22に近い位置）に配置され、後側の２個の空気流入量規制装置38,39は、後側の加熱装置17と対応する位置（前側の加熱装置16の吸気部22よりも後側の加熱装置17の吸気部30に近い位置）に配置されている。 In the laver maker 1 installed in the building 2, a communication path 35 is formed in the building 2 between the exhaust part 34 of the drying chamber 12 and the intake parts 22 and 30 of the heating chamber 13. . The communication passage 35 includes four air inflow amount regulating devices 36 to 39 for restricting the inflow amount of air flowing from the exhaust portion 34 of the drying chamber 12 to the intake portions 22 and 30 of the heating chamber 13. Are arranged side by side. Among these, the two front air inflow regulating devices 36 and 37 are located at positions corresponding to the front heating device 16 (the intake portion 22 of the front heating device 16 relative to the intake portion 30 of the rear heating device 17). The rear two air inflow regulating devices 38 and 39 are arranged at positions close to each other, and the rear side heating device 17 corresponds to the rear side heating device 17 (the rear side heating device 22 of the front side heating device 16). (Position close to 17 intake portions 30).

各空気流入量規制装置36〜39は、矩形枠状の枠体40に上下に並べた３枚の横長矩形板状の開閉フィン41を上下回動自在に取付け、モーター等の駆動機構で開閉フィン41を回動させることで乾燥室12の排気部34から加熱室13の吸気部22,30へと流入する空気の流入量を規制するようにしている。なお、各空気流入量規制装置36〜39は、開閉フィン41の回動角度によって開口面積を変化させて空気の流入量を規制するとともに、空気の流入を阻止するように遮蔽することもできる。 Each of the air inflow control devices 36 to 39 includes three horizontally long rectangular plate-like opening / closing fins 41 arranged vertically on a rectangular frame-like frame body 40, and is attached to the opening / closing fins by a drive mechanism such as a motor. By rotating 41, the inflow amount of air flowing from the exhaust section 34 of the drying chamber 12 to the intake sections 22 and 30 of the heating chamber 13 is regulated. Each of the air inflow amount regulating devices 36 to 39 can change the opening area according to the rotation angle of the opening and closing fins 41 to regulate the air inflow amount, and can also shield the air inflow.

各空気流入量規制装置36〜39は、コントローラー42で制御される。このコントローラー42には、乾燥室12の内部の温度や湿度を計測するセンサー43が接続されており、センサー43で計測された温度や湿度に応じて加熱装置16,17や空気流入量規制装置36〜39を制御するようにしている。なお、センサー43は、乾燥室12の内部に複数個設けられており、乾燥室12の前側部分と後側部分などのように乾燥室12の内部の温度や湿度を部分的に計測できるようにしている。また、図１において、44は空気を供給するダクト、45は排気ファン、46は仕切壁を示しており、ダクト44から供給された空気を加熱室13で加熱して乾燥室12に供給し、乾燥室12から排気された加熱空気を排気ファン45から排出する。その際に、一部の加熱空気は、乾燥室12から加熱室13へと流入する。 Each air inflow regulating device 36 to 39 is controlled by the controller 42. A sensor 43 for measuring the temperature and humidity inside the drying chamber 12 is connected to the controller 42. Depending on the temperature and humidity measured by the sensor 43, the heating devices 16 and 17 and the air inflow control device 36 are connected. I try to control ~ 39. A plurality of sensors 43 are provided inside the drying chamber 12 so that the temperature and humidity inside the drying chamber 12 can be partially measured, such as the front and rear portions of the drying chamber 12. ing. In FIG. 1, 44 is a duct for supplying air, 45 is an exhaust fan, 46 is a partition wall, the air supplied from the duct 44 is heated in the heating chamber 13 and supplied to the drying chamber 12, The heated air exhausted from the drying chamber 12 is exhausted from the exhaust fan 45. At that time, part of the heated air flows from the drying chamber 12 into the heating chamber 13.

そして、コントローラー42は、センサー43によって乾燥室12の前側部分の湿度が所定湿度（第１前側所定湿度）よりも高くなっていることを検出した場合には、前側の加熱装置16に対応する空気流入量規制装置36,37を制御して乾燥室12の排気部34から加熱室13の前側の吸気部22に流入する空気の量を減少させる。これにより、乾燥室12の排気部34から加熱室13の前側の吸気部22に流入する空気、すなわち、乾燥室12で海苔生地の乾燥に使用され水分を多量に含んだ（湿度の高い）空気が再び加熱室13で加熱されて乾燥室12に供給されるのを防止し、乾燥室12の前側部分の湿度を良好に低下させることができる。 When the controller 42 detects that the humidity in the front portion of the drying chamber 12 is higher than the predetermined humidity (first front predetermined humidity) by the sensor 43, the air corresponding to the heating device 16 on the front side is detected. The inflow amount regulating devices 36 and 37 are controlled to reduce the amount of air flowing from the exhaust unit 34 of the drying chamber 12 into the intake unit 22 on the front side of the heating chamber 13. As a result, air that flows from the exhaust section 34 of the drying chamber 12 to the intake section 22 on the front side of the heating chamber 13, that is, air that is used to dry the laver dough in the drying chamber 12 and contains a large amount of moisture (high humidity). Can be prevented from being heated again in the heating chamber 13 and supplied to the drying chamber 12, and the humidity of the front portion of the drying chamber 12 can be satisfactorily reduced.

その際に、コントローラー42は、後側の加熱装置17に対応する空気流入量規制装置38,39を制御して乾燥室12の排気部34から加熱室13の前側の吸気部22に流入する空気の量を減少させてもよい。これにより、乾燥室12の排気部34から加熱室13の前側の吸気部22に流入する空気、すなわち、乾燥室12の後側部分で海苔生地の乾燥に使用され水分を多量に含んだ（湿度の高い）空気の一部が再び加熱室13で加熱されて乾燥室12に供給されるのを防止し、乾燥室12の前側部分の湿度を良好に低下させることができる。なお、コントローラー42は、センサー43によって乾燥室12の後側部分の湿度が所定湿度（第２後側所定湿度：後述する第１後側所定湿度よりも低く設定された湿度）よりも高くなっていることを検出した場合にのみ、後側の加熱装置17に対応する空気流入量規制装置38,39を制御して乾燥室12の排気部34から加熱室13の前側の吸気部22に流入する空気の量を減少させてもよい。 At that time, the controller 42 controls the air inflow amount regulating devices 38 and 39 corresponding to the heating device 17 on the rear side, and the air flowing from the exhaust unit 34 of the drying chamber 12 to the intake unit 22 on the front side of the heating chamber 13 The amount of may be reduced. As a result, the air flowing from the exhaust part 34 of the drying chamber 12 to the air intake part 22 on the front side of the heating chamber 13, that is, a large amount of moisture used for drying the laver dough at the rear side part of the drying chamber 12 (humidity) It is possible to prevent a part of the air from being heated again in the heating chamber 13 and supplied to the drying chamber 12, and to reduce the humidity of the front portion of the drying chamber 12 satisfactorily. The controller 42 causes the sensor 43 to increase the humidity of the rear portion of the drying chamber 12 to be higher than a predetermined humidity (second rear predetermined humidity: a humidity set lower than a first rear predetermined humidity described later). Only when it is detected that the air inflow rate regulating devices 38 and 39 corresponding to the heating device 17 on the rear side are controlled to flow from the exhaust portion 34 of the drying chamber 12 to the intake portion 22 on the front side of the heating chamber 13 The amount of air may be reduced.

同様に、コントローラー42は、センサー43によって乾燥室12の後側部分の湿度が所定湿度（第１後側所定湿度）よりも高くなっていることを検出した場合には、後側の加熱装置17に対応する空気流入量規制装置38,39を制御して乾燥室12の排気部34から加熱室13の後側の吸気部30に流入する空気の量を減少させる。これにより、乾燥室12の排気部34から加熱室13の後側の吸気部30に流入する空気、すなわち、乾燥室12で海苔生地の乾燥に使用され水分を多量に含んだ（湿度の高い）空気が再び加熱室13で加熱されて乾燥室12に供給されるのを防止し、乾燥室12の後側部分の湿度を良好に低下させることができる。 Similarly, if the controller 42 detects that the humidity of the rear portion of the drying chamber 12 is higher than the predetermined humidity (first rear predetermined humidity) by the sensor 43, the heating device 17 on the rear side is detected. The amount of air flowing from the exhaust section 34 of the drying chamber 12 to the intake section 30 on the rear side of the heating chamber 13 is reduced by controlling the air inflow amount regulating devices 38 and 39 corresponding to the above. As a result, air flowing from the exhaust section 34 of the drying chamber 12 to the intake section 30 on the rear side of the heating chamber 13, that is, a large amount of moisture used for drying the laver dough in the drying chamber 12 (high humidity) It is possible to prevent the air from being heated again in the heating chamber 13 and supplied to the drying chamber 12, and to reduce the humidity of the rear portion of the drying chamber 12 satisfactorily.

その際に、コントローラー42は、前側の加熱装置16に対応する空気流入量規制装置36,37を制御して乾燥室12の排気部34から加熱室13の後側の吸気部30に流入する空気の量を減少させてもよい。これにより、乾燥室12の排気部34から加熱室13の後側の吸気部30に流入する空気、すなわち、乾燥室12の前側部分で海苔生地の乾燥に使用され水分を多量に含んだ（湿度の高い）空気の一部が再び加熱室13で加熱されて乾燥室12に供給されるのを防止し、乾燥室12の後側部分の湿度を良好に低下させることができる。なお、コントローラー42は、センサー43によって乾燥室12の前側部分の湿度が所定湿度（第２前側所定湿度：前述した第１前側所定湿度よりも低く設定された湿度）よりも高くなっていることを検出した場合にのみ、前側の加熱装置16に対応する空気流入量規制装置36,37を制御して乾燥室12の排気部34から加熱室13の後側の吸気部30に流入する空気の量を減少させてもよい。 At that time, the controller 42 controls the air inflow amount regulating devices 36 and 37 corresponding to the front heating device 16 to flow air from the exhaust portion 34 of the drying chamber 12 into the intake portion 30 on the rear side of the heating chamber 13. The amount of may be reduced. As a result, air flowing from the exhaust section 34 of the drying chamber 12 to the intake section 30 on the rear side of the heating chamber 13, that is, a large amount of moisture used for drying the laver dough in the front portion of the drying chamber 12 (humidity) It is possible to prevent a part of the air from being heated again in the heating chamber 13 and supplied to the drying chamber 12, and to reduce the humidity of the rear portion of the drying chamber 12 satisfactorily. The controller 42 confirms that the humidity of the front portion of the drying chamber 12 is higher than the predetermined humidity (second front predetermined humidity: humidity set lower than the first predetermined humidity described above) by the sensor 43. Only when it is detected, the amount of air flowing from the exhaust unit 34 of the drying chamber 12 to the intake unit 30 on the rear side of the heating chamber 13 by controlling the air inflow amount regulating devices 36 and 37 corresponding to the front heating device 16 May be reduced.

またコントローラー42は、センサー43によって乾燥室12の前側部分の温度が所定温度（前側所定温度）よりも低くなっていることを検出した場合には、前側の加熱装置16を制御して加熱室13から乾燥室12の前側部分に供給する高温の加熱空気の量を増大させる。その際に、前側の加熱装置16に対応する空気流入量規制装置36,37を制御して乾燥室12の排気部34から加熱室13の前側の吸気部22に流入する空気の量を減少させてもよく、また、同時に又は独立して、後側の加熱装置17に対応する空気流入量規制装置38,39を制御して乾燥室12の排気部34から加熱室13の前側の吸気部22に流入する空気の量を減少させてもよい。 In addition, when the controller 42 detects that the temperature of the front portion of the drying chamber 12 is lower than the predetermined temperature (the predetermined temperature on the front side) by the sensor 43, the controller 42 controls the heating device 16 on the front side to control the heating chamber 13. The amount of hot heated air supplied to the front part of the drying chamber 12 is increased. At that time, the air inflow control devices 36 and 37 corresponding to the front heating device 16 are controlled to reduce the amount of air flowing from the exhaust section 34 of the drying chamber 12 to the front intake section 22 of the heating chamber 13. Alternatively, simultaneously or independently, the air inflow control devices 38 and 39 corresponding to the heating device 17 on the rear side are controlled so that the exhaust portion 34 of the drying chamber 12 and the intake portion 22 on the front side of the heating chamber 13 are controlled. You may reduce the quantity of the air which flows in.

同様に、コントローラー42は、センサー43によって乾燥室12の後側部分の温度が所定温度（後側所定温度）よりも低くなっていることを検出した場合には、後側の加熱装置17を制御して加熱室13から乾燥室12の後側部分に供給する高温の加熱空気の量を増大させる。その際に、後側の加熱装置17に対応する空気流入量規制装置38,39を制御して乾燥室12の排気部34から加熱室13の後側の吸気部30に流入する空気の量を減少させてもよく、また、同時に又は独立して、前側の加熱装置16に対応する空気流入量規制装置36,37を制御して乾燥室12の排気部34から加熱室13の後側の吸気部30に流入する空気の量を減少させてもよい。 Similarly, when the controller 42 detects that the temperature of the rear portion of the drying chamber 12 is lower than the predetermined temperature (rear predetermined temperature) by the sensor 43, the controller 42 controls the rear heating device 17. Thus, the amount of high-temperature heated air supplied from the heating chamber 13 to the rear portion of the drying chamber 12 is increased. At that time, the amount of air flowing from the exhaust part 34 of the drying chamber 12 to the intake part 30 on the rear side of the heating chamber 13 is controlled by controlling the air inflow amount regulating devices 38 and 39 corresponding to the heating device 17 on the rear side. The air intake amount regulating devices 36 and 37 corresponding to the front heating device 16 may be controlled simultaneously or independently to control the intake air on the rear side of the heating chamber 13 from the exhaust part 34 of the drying chamber 12. The amount of air flowing into the unit 30 may be reduced.
