Summary of the Invention

Problems to be Solved by the Invention

[0006] In recent years, in order to promote mass production of dried laver, the laver manufacturing machine, particularly the drying chamber, has been made longer (larger).

[0007] However, in the conventional nori (seaweed) manufacturing machine described above, hot air generated by a front combustion furnace equipped with a combustion burner at its front end and a rear combustion furnace equipped with a combustion burner at its rear end is supplied to the drying chamber, and the nori dough is dried inside the drying chamber. As a result, the temperature distribution inside the drying chamber becomes uneven, and in particular, the temperature drops at the rear end of the front combustion furnace where there is no combustion burner and at the front end of the rear combustion furnace (the center of the drying chamber), which may prevent the nori dough from drying properly. [Means for solving the problem]

[0008] Therefore, in the present invention according to claim 1, a nori manufacturing machine has a drying device that dries nori dough, which has been formed on a nori mat, with hot air while conveying it in the front-to-back direction inside a drying chamber, and combustion furnaces are arranged front to back on the side of the drying chamber, extending in the front-to-back direction along the conveying direction of the nori mat, and combustion burners are provided at the front end of the front combustion furnace and the rear end of the rear combustion furnace, and a heat source different from the combustion burner is provided at the rear end side of the front combustion furnace and at the front end side of the rear combustion furnace.

[0009] Furthermore, in the present invention according to claim 2, a gap is provided between the front combustion furnace and the rear combustion furnace, and the heat source is placed in that gap, in the present invention according to claim 1.

[0010] Furthermore, in the present invention according to claim 3, in the present invention according to claim 1, the rear end of the front combustion furnace and the front end of the rear combustion furnace are arranged side by side, and the heat source is placed on the side of the rear end of the front combustion furnace and the side of the front end of the rear combustion furnace. [Effects of the Invention]

[0011] Furthermore, the present invention provides the following effects.

[0012] In other words, the present invention provides a nori (seaweed) manufacturing machine having a drying device that dries nori dough, which has been formed on a nori mat, with hot air while it is transported in the front-to-back direction inside a drying chamber. Combustion furnaces are arranged front and back on the sides of the drying chamber, extending in the front-to-back direction along the transport direction of the nori mat. Combustion burners are provided at the front end of the front combustion furnace and the rear end of the rear combustion furnace. A heat source different from the combustion burner is provided at the rear end of the front combustion furnace and the front end of the rear combustion furnace. Therefore, even if the temperature drops at the rear end of the front combustion furnace and the front end of the rear combustion furnace (the center of the drying chamber) where combustion burners are not provided, it can be compensated for by a heat source different from the combustion burner. This makes it possible to equalize the temperature distribution inside the drying chamber and dry the nori dough well.

[0013] In particular, if a gap is provided between the front and rear combustion furnaces, and the heat source is placed in that gap, it is possible to accommodate the lengthening (enlargement) of drying chambers that has been required in recent years due to the mass production of dried seaweed.

[0014] Furthermore, if the rear end of the front combustion furnace and the front end of the rear combustion furnace are arranged side by side, and the heat source is placed on the rear end side of the front combustion furnace and the front end side of the rear combustion furnace, the heat source can be retrofitted to an existing seaweed processing machine. [Brief explanation of the drawing]

[Figure 3] A left-side explanatory diagram showing the inside of the drying apparatus. [Figure 4] Plan view diagram. [Figure 5] Rear view diagram. [Figure 6] A left-side explanatory diagram showing the inside of the drying apparatus. [Figure 7] Plan view diagram. [Figure 8] Rear view diagram. [Modes for carrying out the invention]

[0016] The specific configuration of the laver manufacturing machine according to the present invention will be described below while referring to the drawings. In the following description, the right side in the drawings will be described as the front side.

[0017] As shown in FIGS. 1 and 2, the laver manufacturing machine 1 is arranged with a manufacturing machine 2 and a dryer 3 arranged side by side in the front and rear. Inside these manufacturing machine 2 and dryer 3, there are intermittent conveying devices 6, 7, 8 for continuously and intermittently conveying a plurality of laver trays 4 detachably stretched side by side in the left - right width direction (refer to FIGS. 5 and 8).

[0018] In this laver manufacturing machine 1, the laver tray 4 is conveyed from the upper front end to the upper rear end of the manufacturing machine 2 by the intermittent conveying device 6 of the manufacturing machine 2 together with the tray frame 5, and then is transferred from the intermittent conveying device 6 of the manufacturing machine 2 to the intermittent conveying device 7 above the dryer 3. After that, the laver tray 4 is conveyed from the upper front end to the upper rear end of the dryer 3 by the intermittent conveying device 7 above the dryer 3 together with the tray frame 5, and then is folded downward at the upper rear end of the dryer 3 and conveyed from the rear end of the middle part to the front end of the middle part of the dryer 3, and is transferred from the intermittent conveying device 7 above the dryer 3 to the intermittent conveying device 8 below the dryer 3 through the intermittent conveying device 6 of the manufacturing machine 2 at the front end of the middle part of the dryer 3. After that, the laver tray 4 is conveyed from the front end of the middle part to the rear end of the middle part of the dryer 3 by the intermittent conveying device 8 below the dryer 3 together with the tray frame 5, and then is folded downward at the rear end of the middle part of the dryer 3 and conveyed from the lower rear end to the lower front end of the dryer 3, and is transferred from the intermittent conveying device 8 below the dryer 3 to the intermittent conveying device 6 of the manufacturing machine 2 again at the lower front end of the dryer 3. After that, the laver tray 4 is conveyed from the lower rear end to the lower front end of the manufacturing machine 2 by the intermittent conveying device 6 of the manufacturing machine 2 together with the tray frame 5, and then is folded upward at the lower front end of the manufacturing machine 2. As a result, a conveying path for continuously conveying the laver tray 4 together with the tray frame 5 is formed in the laver manufacturing machine 1.

[0019] [[ID=!15]]On this conveying path, a forming device 9 provided in the manufacturing machine 2, a dehydrating device 10, a drying device 11 provided in the dryer 3, and a peeling device 12 provided in the manufacturing machine 2 are arranged in order.

[0020] The laver manufacturing machine 1 operates the intermittent conveying devices 6, 7, 8, the papermaking device 9, the dehydrating device 10, the drying device 11, and the peeling device 12 in联动 with each other by the driving device 13. A control device 14 is connected to the driving device 13, and the driving of the papermaking device 9, the dehydrating device 10, the drying device 11, and the peeling device 12 is controlled by the control device 14 via the driving device 13.

[0021] Then, the laver manufacturing machine 1 conveys a plurality of laver mats 4 together with the mat frames 5 along the conveying path, supplies a laver raw material (raw material) composed of laver thallus and moisture to the upper surface of each laver mat 4 by the papermaking device 9, and makes a laver sheet of a predetermined shape (for example, rectangular). After that, the dehydrating device 10 dehydrates the laver sheet, and then, the drying device 11 forcibly dries the laver sheet with hot air to obtain dried laver. After that, the peeling device 12 peels the dried laver from each laver mat 4, and then, the operation of conveying the laver mat 4 together with the mat frame 5 back to the papermaking device 9 is continuously repeated. Thereby, the laver manufacturing machine 1 continuously manufactures a plurality of dried lavers simultaneously from the laver sheet.

[0022] In this laver manufacturing machine 1, the drying device 11 accommodates the intermittent conveying devices 7, 8 inside a drying chamber 15 having a hollow rectangular box shape extending in the front and rear directions, and a furnace chamber 16 extending in the front and rear directions along the drying chamber 15 is provided on the left side of the drying chamber 15. The outside air is heated in the furnace chamber 16 to generate hot air, and the generated hot air is supplied from the lower part of the furnace chamber 16 into the drying chamber 15.

[0023] Thereby, the laver manufacturing machine 1 dries the laver sheet copied on the laver mat 4 by the manufacturing machine 2 with the hot air generated by the drying device 11 while conveying the laver mat 4 together with the mat frame 5 in the front and rear directions by the intermittent conveying devices 7, 8 inside the drying chamber 15.

[0024] As shown in Figures 3 to 5, this drying apparatus 11 has a hollow rectangular box-shaped furnace chamber 16 that extends front to back, with multiple fans 17 arranged front to back at the top of the chamber for drawing in outside air. Inside the furnace chamber 16, hollow cylindrical combustion furnaces 18 and 19 are arranged front to back with a gap between them, extending in the direction of transport of the seaweed mats 4 (front to back direction). A combustion burner 20 is attached to the front end of the front combustion furnace 18, and a combustion burner 21 is attached to the rear end of the rear combustion furnace 19. Furthermore, the base end (rear end) of a hot air pipe 22 extending forward and backward along the combustion furnace 18 is connected to the upper rear end of the front combustion furnace 18, and the base end (lower end) of an exhaust pipe 23 extending vertically is connected to the tip end (front end) of the hot air pipe 22. Additionally, the base end (front end) of a hot air pipe 24 extending forward and backward along the combustion furnace 19 is connected to the upper front end of the rear combustion furnace 19, and the base end (lower end) of an exhaust pipe 25 extending vertically is connected to the tip end (rear end) of the hot air pipe 24.

[0025] Furthermore, the drying apparatus 11 has heat sources 26 and 27, which have different heat sources from the combustion burners 20 and 21, arranged in the space (gap) formed between the rear of the front combustion furnace 18 and the front of the rear combustion furnace 19, aligned front to back along the conveying direction (front to back direction) of the seaweed mat 4. Here, the heat sources 26 and 27 are arranged in correspondence with each fan 17.

[0026] These heat sources 26 and 27 only need to have a heat source different from the combustion burners 20 and 21, and may be electric heaters or combustion burners, or they may be supply ports for supplying air heated by electric heaters or combustion burners.

[0027] The drying apparatus 11 controls the fan 17, combustion burners 20, 21, and heat sources 26, 27 with the control device 14 to heat the outside air drawn in by the fan 17 with the combustion burners 20, 21 (combustion furnaces 18, 19 and hot air pipes 22, 24) and heat sources 26, 27 to generate hot air, which is then supplied to the inside of the drying chamber 15. Furthermore, the drying apparatus 11 measures the internal temperature distribution using temperature sensors inside the drying chamber 15 to ensure that the temperature distribution inside the drying chamber 15 is uniform.

[0028] In the seaweed manufacturing machine 1 described above, the heat sources 26 and 27 are placed between the front and rear combustion furnaces 18 and 19, but the machine is not limited to this arrangement, and may be placed overlapping with the front and rear combustion furnaces 18 and 19.

[0029] As shown in Figures 6 to 8, the drying apparatus 29 of the nori manufacturing machine 28 has multiple fans 31 arranged front to back at the top of a hollow rectangular box-shaped furnace chamber 30 that extends front to back, and hollow cylindrical combustion furnaces 32 and 33 arranged front to back inside the furnace chamber 30 that extend front to back along the conveying direction (front to back direction) of the nori mat 4. A combustion burner 34 is attached to the front end of the front combustion furnace 32 and a combustion burner 35 is attached to the rear end of the rear combustion furnace 33. Furthermore, the base end (rear end) of a hot air pipe 36 extending forward and backward along the combustion furnace 32 is connected to the upper rear end of the front combustion furnace 32, and the base end (lower end) of an exhaust pipe 37 extending vertically is connected to the tip end (front end) of the hot air pipe 36. Additionally, the base end (front end) of a hot air pipe 38 extending forward and backward along the combustion furnace 33 is connected to the upper front end of the rear combustion furnace 33, and the base end (lower end) of an exhaust pipe 39 extending vertically is connected to the tip end (rear end) of the hot air pipe 38.

[0030] Furthermore, the drying apparatus 29 has heat sources 40 and 41, each having a heat source different from the combustion burners 34 and 35, arranged front to back along the conveying direction (front to back direction) of the seaweed mat 4 in the space (space) between the rear end side of the front combustion furnace 32 and the front end side of the rear combustion furnace 33. Here, the heat sources 40 and 41 are arranged in correspondence with each fan 31. These heat sources 40 and 41 also only need to have a heat source different from the combustion burners 34 and 35, and may be electric heaters or combustion burners, or they may be supply ports for supplying air heated by electric heaters or combustion burners.

[0031] The drying apparatus 29 controls the fan 31, combustion burners 34, 35, and heat sources 40, 41 with the control device 14 to heat the outside air drawn in by the fan 31 with the combustion burners 34, 35 (combustion furnaces 32, 33 and hot air pipes 36, 38) and heat sources 40, 41 to generate hot air, which is then supplied to the inside of the drying chamber 15. Furthermore, the drying apparatus 29 measures the internal temperature distribution using temperature sensors inside the drying chamber 15 to ensure that the temperature distribution inside the drying chamber 15 is uniform.

[0032] As described above, the nori manufacturing machine 1 and 28 have drying devices 11 and 29 that dry the nori dough made on the nori mat 4 with hot air while transporting it in the front-to-back direction inside the drying chamber 15. Combustion furnaces 18, 19, 32, and 33 are arranged front to back on the sides of the drying chamber 15, extending in the front-to-back direction along the transport direction of the nori mat 4. Combustion burners 20, 21, 34, and 35 are provided at the front ends of the front combustion furnaces 18 and 32 and at the rear ends of the rear combustion furnaces 19 and 33, and heat sources 26, 27, 40, and 41 different from the combustion burners 20, 21, 34, and 35 are provided at the rear end of the front combustion furnaces 18 and 32 and at the front end of the rear combustion furnaces 19 and 33.

[0033] Therefore, in the nori manufacturing machine 1,28 with the above configuration, even if the temperature drops at the rear end of the front combustion furnaces 18,32 and the front end of the rear combustion furnaces 19,33 (the central part of the drying chamber 15), where combustion burners 20,21,34,35 are not provided, it can be compensated for by heat sources 26,27,40,41 different from the combustion burners 20,21,34,35, thereby equalizing the temperature distribution inside the drying chamber 15 and enabling good drying of the nori dough.

[0034] Furthermore, the seaweed manufacturing machine 1 described above has a configuration in which a gap is provided between the front combustion furnace 18 and the rear combustion furnace 19, and heat sources 26 and 27 are placed in that gap.

[0035] Therefore, the seaweed manufacturing machine 1 with the above configuration can accommodate the lengthening (enlargement) of the drying chamber 15 that has been required in recent years due to the mass production of dried seaweed.

[0036] Furthermore, the seaweed manufacturing machine 28 is configured such that the rear end of the front combustion furnace 32 and the front end of the rear combustion furnace 33 are placed side by side, and heat sources 40 and 41 are placed on the rear end side of the front combustion furnace 32 and the front end side of the rear combustion furnace 33.

[0037] Therefore, with the above-described configuration of the seaweed manufacturing machine 28, heat sources 40 and 41 can be retrofitted to an existing seaweed manufacturing machine. [Explanation of symbols]
