Description

[Detailed description of the invention] This invention relates to a fish drying device that can dry fish for a colored finish and a pewter finish. The present invention relates to a fish drying device that enables roasting for color finishing or pewter drying using a method suitable for the fish by appropriately mixing the fish.

The drying finish of fish can be roughly divided into colored roasting finish, which is dried with hot air that contains smoke, and pewter drying finish, which is dried with hot air that does not contain smoke.
Depending on the type of fish, production area, etc., humid hot air may dry the fish more effectively than dry hot air because special phenomena such as ``effect'' occur.

Therefore, the optimal drying conditions for fish must be adjusted depending on the fish to be dried.

On the other hand, the inventor of this application previously proposed a drying device for fish that can perform colored drying finishing, drying in the open air, etc. in one device (Utility Model Publication No. 50-479), but even with these devices, Fine adjustment of the gas sent into the drying chamber is not possible.

This drying device has a heat exchanger and a rectifier connected to one end of the drying chamber, and the heat exchanger has a flue from the burner inside, and a sirocco that can switch between hot air from the wood burning furnace and outside air. A fan is connected, and a hot air guide groove is installed on the bottom of the drying chamber that leads to a rectifier, and a damper is installed between the drying chamber and the rectifier to send the heated air from the burner to the drying chamber to give the fish a pewter finish. Further, a damper is provided between the rectifier and the hot air guide groove to send the heated air from the wood burning furnace to the drying chamber to color and finish the fish.

With this device, the hot air from the wood burning furnace is sucked directly into the suction side of the sirocco fan, so solids such as ash contained in the hot air are not deposited inside the heat exchanger. Not only is this difficult to remove, but these solids also enter the drying chamber and adhere to the surface of the fish to be dried, reducing the product value.

In view of the above, this application provides a mixing chamber between the wood-burning furnace and the intake fan, and by passing the hot air through this, solids such as ash contained in the hot air are removed, and furthermore, this hot air is made into a mixture suitable for drying fish. This was completed as a result of research aimed at developing a fish drying device that could be roasted or dried in the sun for a colored finish by adjusting the conditions.

That is, the present invention consists of a wood-burning furnace, a wind tunnel-type drying chamber equipped with an intake fan at its base end, and a heat exchanger inside which uses a burner as a heat source, and is capable of suppressing the smoke generated from the wood-burning furnace. etc. are sucked in by an intake fan, guided through a duct to a wind tunnel type drying room, passed through there, and then a part or all of the exhaust air from the drying room is returned to the drying room through a circulation passage provided outside the drying room. In the fish drying apparatus, a mixing chamber is provided between the wood-burning furnace and the intake fan, and a baffle plate is provided inside the mixing chamber in the smoke passing direction to divide the room into two. The above-mentioned duct is introduced from above into one of the chambers, and the tip of the above-mentioned circulation passage that continues from above to the end of the drying chamber is connected to the other chamber, and furthermore, on one side of the other chamber facing the above-mentioned baffle plate. is an open surface with a door, and an opening connected to the suction side of the intake fan is provided on the side perpendicular to the baffle plate.

By adopting the above configuration, the smoke generated from the wood-burning furnace is introduced from above through a duct into one of the mixing chambers, which is divided into two by the baffle, and then into the other chamber, which is divided into two by the baffle. During this process, solids such as ash and soot contained in the smoke fall into the mixing chamber and can be removed from the smoke.

Further, the mixing chamber is divided into two by a baffle plate, and exhaust gas is introduced from above through an exhaust passage into the other chamber, and hot air is introduced from one chamber, where it is efficiently mixed.

Therefore, hot air having a temperature and humidity suitable for the drying conditions of the dried material can be supplied into the drying chamber.

In addition, by opening the door, outside air is taken into the other chamber from the open surface, and this outside air is mixed with the hot air and exhaust air, and hot air with a temperature and humidity suitable for the drying conditions of the drying material is introduced into the drying chamber. Can be supplied.

Therefore, according to this invention, it is possible to carry out roast-drying or day-drying for color finishing using hot air that does not contain solids such as gray soot under conditions suitable for dried fish.

This invention will be explained below based on the illustrated embodiments.

Reference numeral 1 denotes a combustion furnace for burning wood or the like, which includes a combustion chamber 2, and is configured so that smoke generated from the combustion furnace 1 is introduced into a mixing chamber 4 through a duct 3.

The mixing chamber 4 has a large internal volume relative to the air flow rate of the fan, and a baffle plate 5 is installed inside the mixing chamber 4 in the direction of passage of smoke to divide the chamber into two, a chamber 4a and a chamber 4b.
The opening of the duct 3 is connected to the ceiling surface of the front chamber 4b, one side of the front chamber 4b is an open surface covered with a wire mesh 6, a door 7 for opening and closing is attached to one end of the open surface, and a door 7 for opening and closing is attached to one end of the open surface. An outlet portion 8 is provided at the other end, and the outlet portion 8 projects into a wind tunnel type drying chamber 9 and is connected to the suction side of a sirocco fan 10 provided at the base end of the drying chamber 9.

Also, a burner 11 is provided outside the drying chamber 9, and a heat exchanger 12 heated by a sirocco fan 10 and a burner is provided inside the drying chamber 9, and smoke or hot air heated through the heat exchanger 12 is adjusted. A damper 13 is provided for this purpose.

On the other hand, a roller track 14.14 is laid on the bottom surface of the drying chamber 9 from the middle end to the terminal end.
A movable frame 15 is placed on top of the movable frame 15, and a steamer basket 16 containing fish to be dried is placed on a shelf. The smoke or hot air rectified by the damper 13 is passed through this gap to dry the fish in the steamer baskets 16.

Furthermore, an exhaust temperature 17 is provided at the end of the drying chamber 9, a damper 18 is pivotally mounted on one side of the inner wall of the exhaust temperature 17, and the exhaust temperature 17 is further branched to form an exhaust air passage 19. do.

The opening end of the ventilation path 19, with the exhaust damper 20 provided in front thereof, is connected to the ceiling surface of the chamber 4b.

That is, the ventilation passage 19 connects the branch part of the exhaust gas temperature 17 and the ceiling surface of the chamber 4b.

Therefore, outside air is taken into the chamber 4b from the open surface with the door, the flow rate of which is adjusted appropriately depending on the degree of opening of the door, and this outside air is combined with the exhaust air that is regulated from above the chamber and guided into the room with a large volume through the ventilation path 19. The hot air flowing down from above the chamber 4a through the duct 3 reduces the flow rate and drops the solids contained in the hot air into the chamber 4a, which has a large volume, and falls to the bottom of the chamber. The smoke thus separated passes through the baffle plate and is sucked into the sirocco fan.
In b, the exhaust gas is efficiently mixed with the exhaust gas guided from above through the ventilation path 19.

The drying device according to this invention is constructed as described above, but when using this to dry and finish fish with color, open the door 21 of the heat combustion furnace 1 and dry the drying device from wood such as oak or oak. The combustion furnace 1 is heated under such conditions as to generate an appropriate amount of smoke, and the generated smoke is introduced into the mixing chamber 4a from above through the duct 3 while adjusting the ventilation amount with the damper 22.

Since the mixing chamber 4 has a large internal capacity, the smoke introduced from above is decelerated in the chamber 4a and moves laterally, but since the baffle plate 5 obstructs its path, the smoke is not contained in the smoke. The solid contents such as ash and soot stall and fall, and are accumulated in the chamber 4a.

Further, smoke is introduced into the chamber 4b with the wind speed and volume adjusted.

On the other hand, the exhaust gas generated from the surface of the fish by passing through the drying chamber 9 and containing sufficient moisture is caused to pass through the ventilation path 19 in whole or in part by the damper 18, and the air volume of the exhaust gas is reduced by the exhaust damper 20. Adjust it and lead it into the chamber 4b from above.

At the same time, if necessary, the door 7 is opened to introduce outside air into the chamber 4b.

Therefore, smoke, exhaust air, and outside air adjusted to appropriate wind speeds and volumes as described above are mixed in a state suitable for drying the fish to be dried.

Next, the gas mixed as above is transferred to the sirocco fan 10.
The fish stored in the drying chamber 9 is heated to a temperature suitable for drying as it passes through the heat exchanger 12 and is further rectified by the damper 13 before passing through the wind tunnel type drying chamber 9. is dried under its optimum conditions.

On the other hand, when finishing by drying in the daylight, the door 21 of the wood combustion furnace 1 is closed to block the outside air, the damper 22 is closed to stop heating, and the door 7 of the mixing chamber 4b is opened.
Outside air is introduced into the chamber 4b, and if necessary, an appropriate amount of exhaust air is introduced into the chamber 4b through the ventilation path 19 to mix it in the most suitable state for the fish to be dried.

The gases mixed in the chamber 4b as described above are sucked by the sirocco fan 10 and sent into the drying chamber 9 in the same manner as described above, heated by the heat exchanger 12, and transferred to the movable frame 15...
In this case, the hot air passing through the drying chamber 9 contains air that is effective for colored dry finishing. Since it does not contain any ingredients, the fish is dried in the sun in perfect conditions.

Furthermore, in this embodiment, a wire mesh 6 is placed over the open surface of the mixing chamber 4 to prevent paper waste, cloth, etc. from flowing into the mixing chamber 4, and to prevent children etc. from entering the room. .

In this embodiment, the movable underframes 15 are fully loaded on the roller tracks 14, 14 in the drying chamber, and the steamer baskets 16 are shelved on the most advanced movable underframe 15.・Since the method uses smoke or hot air to dry the fish in sequence, the movable frame 15...
Drying is performed by replacing the loading order of ・, and the steamer basket 16...
...It is used to uniformly dry the fish inside.

In addition, in this embodiment, the roller orbit in the drying chamber is 14°14
The movable frame 15... is fully loaded on top, and the fish in the steamer basket 16... placed on the shelf on the most advanced movable frame 15 are sequentially exposed to smoke or hot air and dried. Therefore, after a certain period of time, the movable underframe 15...
Drying is performed by replacing the loading order of..., and the steamer basket 16...
... to uniformly dry the fish inside.

Furthermore, in this embodiment, since the mixing chamber 4 is provided separately from the drying chamber 9, the solid content accumulated in the mixing chamber 4 can be easily removed and the interior of the chamber can be cleaned.

In summary, in this invention, by providing a large mixing chamber 4 between a wood-burning furnace 1 and a wind tunnel type drying chamber 9 in which a heat exchanger 12 is arranged, smoke, exhaust gas, and outside air can be appropriately distributed. It is possible to mix and finish colored roast-drying or day-drying in a method most suitable for the fish.

Therefore, when completely drying roasted or sun-dried fish products, it takes time to dry them from a state that is higher than top drying.
Depending on the product, hot air containing moisture works more effectively than dry hot air and can significantly shorten the drying time. Drying in the above-mentioned manner becomes possible by feeding the material into the device.

In addition, in the case of roasting, since a fan is used to absorb smoke from the wood-burning furnace, ash, soot from incomplete combustion, fine solids, etc. enter the drying chamber along with the smoke and are absorbed onto the surface of the fish. However, this drawback can be easily solved by installing the present device.

Furthermore, according to this invention, since the mixing chamber is provided between the wood-burning furnace and the sirocco fan, it has the same effect as providing a large-capacity air pocket.

Therefore, it is possible to adjust the suction speed of smoke into the drying chamber, and it is also easy to adjust the air volume when drawing outside air, making it possible to adjust the smoke concentration.

Furthermore, when the drying chamber reaches a reduced pressure state or a pressurized state, it can serve to immediately relieve the pressure.

Although it is difficult to adjust the smoke concentration at high temperatures,
In this design, since the mixing chamber is not directly connected to the heat exchanger 12, the temperature can be easily controlled, and since the interior is kept at a low temperature, the smoke concentration can be easily adjusted. At the same time, it is possible to make the solid content contained in the smoke easier to settle.

In addition, in this invention, since the sirocco fan 10 is connected to the mixing chamber, air can be easily taken in by the sirocco fan 10, and furthermore, since it is reheated by the heat exchanger 12, the amount of air is larger than the intake air amount by the amount of expansion due to heating. of heated smoke can be supplied to the drying chamber 9.

Furthermore, this invention can utilize the exhaust heat and moisture in the exhaust gas, and because the exhaust heat can be used, fuel can be saved in the winter.
