[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baked laver producing apparatus for drying and baking sheet-shaped nori, and a fire dryer for preliminarily drying the sheet-shaped nori before baking.

[0002]

2. Description of the Related Art Roasted seaweed is prepared by straining seaweed produced in the sea to form a sheet, and drying it until the water content reaches 2-3% by fire drying and then roasting. Manufactured by. Conventionally, sheet-shaped seaweed (hereinafter simply referred to as "seaweed")
(Also referred to as), a fired dryer that performs fired drying and a seaweed baking machine that roasts fired dried seaweed are separately configured. There was a conveyor dryer.

The proofer dryer has a wooden box having a length and width of about 1 m and a height of about 20 cm, and a hole for allowing hot air to pass through is provided at the bottom of the wooden box. To dry the seaweed using this proof drier, 50 to 10
A large number of pieces of seaweed bundled in units of 0 pieces are placed in a wooden box, and the wooden boxes are stacked in several stages inside a drying oven. Then, hot air of about 80 ° C. was applied to the seaweed in the drying oven for 2 to 5 hours to dry it.

Further, the conveyor dryer has a conveyor,
A large number of partition plates are provided on the conveyor surface so that the seaweed can be conveyed while standing. In this conveyor dryer, a bundle of 50 pieces of seaweed is placed between partition plates on the conveyor, and while being conveyed by the conveyor, hot air of about 100 ° C. is applied to the seaweed from above the conveyor for about 20 minutes to dry it. Was there.

On the other hand, in the conventional seaweed baking machine, for example, the seaweed is arranged on a conveying path composed of a belt conveyor and the like, and the seaweed is passed through the roasting furnace of the seaweed baking machine so that the heat from the heater in the roasting furnace There is one that burns seaweed by heat radiation. As described above, conventionally, after the nori seaweed is bundled and dried with a fire dryer, the nori seaweed is divided into individual pieces and baked with the seaweed roaster.

[0006]

[Problems to be Solved by the Invention] However, in this way,
If you try to dry a sheet of seaweed in a bundle,
Since the central portion is less likely to dry than the outer surface portion of the bundle, unevenness in drying tends to occur. Moreover, when strong hot air is applied to the seaweed or the seaweed is heated to a high temperature in an attempt to dry the central portion of the bundle, as shown in FIGS. 3 (a) to 3 (c),
There was a problem that the seaweed was prone to shrinkage, warpage, and irregularities. In order to avoid this, it is necessary to lower the temperature of the hot air applied to the seaweed as much as possible and dry the seaweed for a long time, but if exposed to hot air for a long time, the flavor and aroma of the seaweed will be lost. .

Further, it took a great deal of time to divide the bundle of seaweed into pieces after burning and drying. Also, since the temperature of the seaweed drops while moving the seaweed from the fire dryer to the seaweed baking machine, it was necessary to raise the temperature again inside the seaweed baking machine, which wasted energy. .

The present invention has been made in view of the above problems, and is capable of drying seaweed in a short time without causing unevenness in drying and deformation, and then rapidly roasting the seaweed and the production of baked seaweed. The purpose is to provide a device.

[0009]

In order to achieve the above-mentioned object, in the fire dryer according to claim 1, nori seaweed is fed one by one to the drying furnace of the first conveyor. Burn-drying is performed by heat radiation from the drying heater while passing through the inside.

As described above, since the seaweed is not fired in a bundle but is dried by firing, it shrinks into seaweed,
It can be dried in a short time without causing deformation such as warpage or unevenness, and does not impair the original flavor and aroma of seaweed. Also, since there is already one piece of seaweed,
You can put the dried seaweed into the seaweed baking machine and bake it quickly. In this case, one by one may be manually transferred from the fire dryer of the present invention to the conventional seaweed baking machine, or the seaweed of the conventional seaweed baking machine may be connected to the end of the first conveyor. You may install a baking machine.

Here, in order to dry the seaweed quickly, it is better to raise the temperature of the seaweed as much as possible. However, when too high a temperature of laver, because deformation as described above in seaweed has occurs, in claim 1, wherein the fire incident dryer, the presser conveyor for pressing the seaweed from the upper side of the first carrying conveyor provided, while sandwiching the laver between the first carrying conveyor and the pressing conveyor have to convey the drying oven
It Since the deformation can be prevented by drying the seaweed while pressing the seaweed in this way, the time required for heating and drying the seaweed can be further shortened.

[0012] In addition, if only to thermal radiation on one side of the nori, because the seaweed that has not yet been dried in the warp tends, claim
As described in Item 2 , an upper drying heater is provided on the upper side of the first transport path, and a lower drying heater is provided on the lower side of the first transport path to radiate heat from above and below toward the first transport path. You should add it. In this way, the seaweed can be made less prone to warp and the time required to dry the seaweed can be shortened.

In the fired dryer according to the second aspect, when dust such as debris of seaweed during transportation falls on the radiating portion of the lower drying heater, heat radiation can be hindered or smoldered. There is a nature. Therefore, as described in claim 3, it is preferable that the radiation portion of the lower drying heater is formed as a surface and the surface is inclined so that the dust can slide down. This can prevent dust from accumulating on the lower drying heater.

To dry the seaweed in the shortest possible time,
As described in claim 4 , a blower may be provided so that the air in the drying furnace is applied to the seaweed. Thus, if the air in the drying furnace is applied to the seaweed in addition to the heat radiation, the water content of the seaweed is easily evaporated, so that the seaweed can be fire-dried in a short time.

As described above, according to the fired dryer of any one of claims 1 to 4 , the seaweed can be dried in a short time without causing unevenness in drying and deformation, and then baked quickly. You can In order to achieve the above object, as described in claim 5 , a baked laver production apparatus comprising the fired dryer according to any one of claims 1 to 4 and a laver baking machine is configured. After firing and drying the seaweed, the seaweed baking machine may be baked by heat radiation from the roasting heater while passing through the roasting furnace of the seaweed baking machine by the second conveyor. In this way, after burning and drying, the seaweed can be quickly moved to the seaweed baking machine, and the temperature of the seaweed does not drop so much, so it is possible to eliminate the energy waste of raising the temperature again. Since it is not necessary to raise the temperature again, the length of the roasting furnace and the time required for roasting can be shortened as compared with the conventional seaweed baking machine.

Here, the drying furnace and the roasting furnace may be separate, but if the seaweed is exposed to the outside air while being transferred from the drying furnace to the roasting furnace, the temperature of the seaweed will drop. Further, the first transfer conveyor in the drying furnace and the second transfer conveyor in the roasting furnace may be configured separately, but it is necessary to separately provide driving means. Therefore, as described in claim 6, it is preferable that the drying furnace and the roasting furnace are integrated with each other, and the first transfer conveyor and the second transfer conveyor are integrated with each other. In this way, the seaweed will not come into contact with the outside air and its temperature will not drop, so that energy can be further saved and the length of the roasting furnace and the time required for roasting can be shortened. Since only one conveyor drive means is required, the device configuration can be simplified.

In order to shorten the time for baking the seaweed ,
As described in claim 7 , an upper roasting heater is provided on the upper side of the second transport path, and a lower roasting heater is provided on the lower side of the second transport path so that heat is applied from above and below toward the second transport path. You may make it radiate. In this way, the temperature of the seaweed can be raised quickly, so that the roasting time and the length of the roasting furnace can be shortened , and the seaweed can be baked more uniformly and beautifully.

Here, if dust such as broken pieces of seaweed during transportation falls on the radiating portion of the lower roasting heater, there is a possibility that heat radiation will be hindered or smoked. Therefore, as described in claim 8 , if the radiation portion of the lower roasting heater is formed as a surface and the surface is inclined so that the dust can slide down, the dust can be deposited on the lower roasting heater. Can be prevented.

It is provided in the upper part of the flame drying zone 8. The blower propeller 32 is rotationally driven by a blower motor 33 provided outside the heating furnace 4.

Further, an upper roasting heater 44a and a lower roasting heater 44b (collectively referred to as "roasting heaters 44") are provided on the ceiling and floor of the baking zone 10, respectively. A large number are arranged along the line 12, and heat is radiated toward a conveyance path formed by the conveyance conveyor 12 as a second conveyance path. The roasting heater 44 is the same as the drying heater 30 described above. Further, similar to the lower drying heater 30b, the lower roasting heater 44b is installed with its radiating surface inclined so that dust can slide down. The amount of electric power supplied to the roasting heater 44 can be adjusted to adjust the intensity of infrared rays emitted from the roasting heater 44 to an intensity suitable for baking seaweed.

Looking at the heating furnace 4 as a whole, a plurality of exhaust ducts 46 are provided in the lower part of the heating furnace 4 as exhausting means for discharging the water vaporized from the seaweed to the outside of the heating furnace 4. Air can be discharged to the outside of the baked laver manufacturing device 2. Further, a plurality of intake holes 48 as intake means for taking in the outside air are provided in the upper part of the heating furnace 4, and the exhaust duct 46 discharges the air containing the water evaporated from the seaweed while the fresh outside air is discharged. Is supplied into the heating furnace 4. The intake hole 48 is provided with an air valve 49, and the amount of air supplied through the air valve 46 can be adjusted by rotating the air valve 49.

In addition, the firing zone 10 of the firing drying zone 8

There is provided a roller cover 51 that forms an insertion port 12a that can be inserted one by one on the conveyor.

Each roller of this supply conveyor 50 can freely rotate, and the operator of the main burned seaweed production apparatus 2 can
By placing the seaweed on the supply conveyor 50 and pushing it toward the transfer conveyor 12, the seaweed can be easily inserted into the heating furnace 4. Further, on the side of the transport drive roller 14,
The discharge roller 52 is provided in parallel with the transport driving roller 14. The discharge roller 52 is configured such that the conveyance drive roller 14 rotates by a pulley (not shown) and the rubber belt 5.
By being transmitted via No. 4, the nori is rotated so as to be discharged to the outside of the baked nori manufacturing device 2. The discharge roller 5
A large number of filamentous materials such as synthetic fibers are planted on the side peripheral surface of 2 like a brush, and the seaweed can be reliably discharged without slipping.

A caster 58 for moving the roasted laver producing apparatus 2 and the roasted laver producing apparatus 2 are provided under the furnace bottom 6.
A bolt 60 is provided as a fixing means for fixing the to the floor. The cast seaweed production apparatus 2 can be reliably fixed to the ground by moving the grilled seaweed production apparatus 2 to an appropriate place by the caster 58 and then turning the bolt 60 to bring it into contact with the floor.

In the grilled laver producing apparatus 2 of the present embodiment configured as described above, when the laver is inserted one by one from the insertion port 12a of the conveyor 12, as shown in FIG. The press conveyor 28 sandwiches the inserted seaweed and conveys it in the fire drying zone 8. While the seaweed is transported in the fire-drying zone 8, it receives heat radiation from the drying heater 30 from above and below, and its temperature is raised to about 80 ° C., for example. Here, the temperature of each drying heater 30 is adjusted by the amount of electric power supplied to the drying heater 30 itself, and therefore, the intensity of heat radiation by the drying heater 30 is adjusted to an appropriate intensity for drying seaweed. It Then, from above the transport conveyor 12, wind is applied to the seaweed by the blower propeller 32.

Thus, the seaweed, which had a water content of 5 to 8% before being inserted into the heating furnace 4, was deprived of its water content while passing through the fired drying zone 8 to a water content of 2 to 3%. Can be lowered. Here, the time during which the seaweed passes through the heat-drying zone 8 is adjusted by adjusting the rotation speed of the transfer drive motor 18 and setting the transfer speed of the transfer conveyor 12 so that an appropriate time for drying the seaweed ( (For example, 3 to 4 seconds).

The seaweed that has just been inserted releases a large amount of water into the heating furnace 4. However, since the steam is discharged through the intake holes 48 and the exhaust duct 46, the drying can be performed more effectively. . Subsequently, when the seaweed enters the baking zone 10, the temperature thereof is raised to, for example, 180 ° C. to 190 ° C. by heat radiation by the roasting heater 44. here,
The temperature of each roasting heater 44 is adjusted by the amount of electric power supplied to the roasting heater 44 itself, so that the intensity of heat radiation by the roasting heater 44 is adjusted to an intensity suitable for baking seaweed.

Then, the seaweed is baked while passing through the baking zone 10, and its color changes from purple to green. Here, the time during which the seaweed passes through the baking zone 10 is adjusted by adjusting the rotation speed of the transfer drive motor 18 and setting the transfer speed of the transfer conveyor 12, so that the time suitable for baking the seaweed (for example, 3 to 4 seconds). However, in the present embodiment, since the first conveyor and the second conveyor are integrally formed, the conveyor drive motor 18 is controlled to determine the time for the seaweed to pass through the fire drying zone 8. Naturally, the time for passing through the baking zone 10 is also determined. That is, the temperature of the drying heater 30 and the roasting heater 4
The temperature of 4, the transport speed of the transport conveyor 12, the wind strength of the blower propeller 32, and the like are adjusted comprehensively.

In the baking zone 10 as well, since some water evaporates from the seaweed, an intake hole 48 and an exhaust duct 46 are provided. In this way, according to the grilled laver producing apparatus 2 of the present embodiment, for example, 10,000 to 1 per hour.
At the speed of 15,000 sheets, you can burn and dry the seaweed and continue baking.

As described above, in the grilled seaweed production apparatus 2 of the present invention, the seaweed is conveyed one by one, fire-dried, and then continuously baked. Since it is not necessary to raise the temperature, the time required for baking the seaweed and the length of the heating furnace can be shortened, and energy can be effectively used.

In addition, since the seaweed is dried one by one in the hot-drying zone 8, the hot-drying can be carried out in a short time, and the flavor and aroma originally possessed by the seaweed are not impaired. In addition, the presser conveyor 28 and the transfer conveyor 12
Since it is dried in a state sandwiched between and, even if the seaweed is heated to high temperature or blown with strong hot air, it does not shrink, warp or become uneven.

Further, the drying heater 30 is attached to the firing drying zone 8
Since it is provided on the ceiling and floor of the conveyor, that is, above and below the conveyor 12, and heat is radiated to the front and back of the seaweed, it can be dried more uniformly in a shorter time. And
In particular, since the lower drying heater 30b is installed on the floor with the radiating surface thereof being inclined so that dust and the like may slide down, the debris of seaweed, etc., will be removed from the lower drying heater 30b.
It does not deposit on the emitting surface of b. Therefore, it is possible to prevent the heat radiation from being blocked by the pieces of seaweed, the pieces of seaweed to be smoked on the lower drying heater 30b, and to be ignited.

Further, since the air in the drying furnace 4 is applied to the seaweed by the blower propeller 32, the seaweed can be dried more effectively in a short time. Further, in the baking zone 10, since the roasting heaters 44 are provided on the ceiling and floor of the baking zone 10, that is, above and below the conveyer conveyor 12, and heat is radiated to the front and back of the seaweed, the heat is evenly distributed in a shorter time. You can bake it.

In particular, since the lower roasting heater 44b is installed on the floor with its radiating surface inclined so that dust and the like will slide down, even if debris may fall, It does not deposit on the side roasting heater 44b. Therefore, it is possible to prevent the heat radiation from being blocked by the pieces of seaweed, and the pieces of seaweed to be smoked or ignited on the lower roasting heater 44b.

For example, in the above-mentioned embodiment, the baked laver production apparatus 2 in which the fired-drying machine and the seaweed baking machine are integrated has been described, but the fired-drying machine alone is configured and combined with the conventional seaweed baking machine. You may comprise a seaweed manufacturing apparatus. In this case, the firing dryer only needs to omit the baking zone 10 from the grilled seaweed production apparatus 2 of this embodiment, and the same effect as that obtained in the fire drying zone 8 is obtained.

Further, in the above embodiment, the heat insulating material 13 is provided in the hollow portion such as the wall forming the heating furnace 4, but any heat insulating material may be used. Further, the wall portion may be formed by using a heat-insulating plate-like body instead of making it hollow. In addition, when the inner surface of the wall or the like is formed of a metal plate, infrared rays can be reflected, and fire drying and roasting of seaweed can be efficiently performed. It is preferable to form the metal plate with a metal that does not rust such as stainless steel.

In the above embodiment, the conveyor belt 18,
As the pressing belt 38, a glass fiber reinforced Teflon mesh belt formed in a 5 mm square mesh was used.
Not limited to this, it is formed of metal such as stainless steel,
Any belt may be used as long as it has heat resistance. In addition, it is preferable to form the belt in a mesh shape because infrared rays and air can pass therethrough, and fire drying and roasting can be easily performed.

In the above embodiment, the drying heater 30,
The roasting heater 44 is made of ceramic in the form of a plate, but is not limited to this, and various infrared lamps such as tube-shaped infrared lamps using quartz tubes and far-infrared lamps that serve as infrared radiation sources. Anything will do as long as it is.

Further, in the above embodiment, the lower drying heater 3
Regarding 0b and the lower roasting heater 44b, these are formed into a plate-like body and the radiating portion thereof is formed into a planar shape, but it is not limited to the plate-like body. For example, various infrared lamps may be housed in a housing, and the upper surface of the housing may be formed of glass or the like that transmits infrared rays to serve as a radiation surface.
