Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a continuous boiling device for small fish, and in particular to a conveyor device for disposing a heat dissipation pipe in a boiling tank and for taking out boiled small fish. boil tank l1j1
This invention relates to a continuous boiling device for small fish, which is provided with a partial heating section made up of a heat radiation pipe near the first section.

[Prior art]

Conventionally, a continuous boiling device is known in which a screw conveyor is placed in a boiling tank with a rounded bottom section, and small fish are boiled while being transferred (Utility Model Publication No. 61-3347).
However, since the boiling tank is heated from the outside with a burner or the like, it has the disadvantage that temperature unevenness tends to occur. Therefore, we divided the boiling tank into upper and lower halves with a wire mesh.
A boiling device has been proposed in which a screw conveyor is disposed in the upper part, and a steam pipe having a jet nozzle bent into a plane shape and a hot water pipe having a jet nozzle are disposed in the lower part. For example, an automatic boiling device described in Japanese Patent Application Laid-open No. 54-76877 is an example of this.

Furthermore, a continuous boiling device has conventionally been used in which a mesh belt for taking out boiled small fish is arranged at an angle, and one end of the mesh belt is immersed in a boiling tank.

[Problems with conventional technology]

However, in the boiling device disclosed in Japanese Patent Application Laid-open No. 54-76877, the boiling tank is divided into upper and lower halves by a wire mesh, with a screw conveyor in the upper part and a steam pipe bent into a flat shape and a hot water pipe in the lower part. The provision of pipes increases the size of the device, and it is necessary to add an additional steam pipe with an injection nozzle to stir the small fish, resulting in a complicated structure and the possibility of small fish remaining after use. There was a problem.

In addition, in a continuous boiling device in which one layer of the mesh belt conveyor is immersed in a boiling tank and the boiled small fish are taken out, the boiled small fish are not spread evenly on the mesh belt and are unevenly distributed. Therefore, there was a problem in that it was difficult for the subsequent dehydration process and drying process to proceed smoothly.

Furthermore, the small fish in the mesh belt are transported to the other end of the mesh belt and sent to the next process.
There was a problem in that some of the waste was carried along the mesh belt, deposited in the boiling tank below the mesh belt conveyor, and easily rotted.

The present invention has been made against the background of the above circumstances, and an object of the present invention is to provide a continuous boiling device that does not leave any small fish after use and is simple and compact in S construction, and a continuous boiling device for boiled small fish. A continuous boiling device that can uniformly place small fish on a conveyor device, and a continuous boiler that can prevent light small fish from adhering to the conveyor device and returning to its original position and depositing in a boiling tank. The goal is to provide equipment.

[Means for Solving the Problems of the Prior Art] The present invention has been made to achieve the above object, and the gist of the present invention is as follows: A. A screw conveyor is arranged in a boiling tank. In a continuous boiling device capable of boiling small fish while transferring them, a plurality of heat radiation pipes through which heated steam can pass are arranged at least on the lower outer side of the screw conveyor on a substantially concentric cylindrical surface around the axis of the screw conveyor. B. In the continuous boiling device for small fish described in item A above, each of the heat radiation pipes faces in the same direction as the screw conveyor, and adjacent heat radiation pipes are in contact with each other or are not in contact with each other. At the same time, a heat dissipation pipe-free area is provided below the axis of the screw conveyor, where no heat dissipation pipe is disposed, and a gap is provided between the bottom surface of the boiling tank and the heat dissipation pipe. The continuous boiling apparatus for small fish is characterized in that the bottom surface of the boil tank is formed so that the height gradually decreases as it approaches the area where no heat radiation pipe exists; A continuous boiling device that has a transfer device that can transfer fish while boiling it, and has one end of a conveyor device that can take out boiled small fish near the exit of the transfer device inclined in a boiling tank. . A continuous boiling device for small fish, characterized in that a partial heating section composed of a heat dissipating vibrator is provided near the bottom of the boiling tank between the exit side of the transfer device and one end of the conveyor device; D. It has a transfer device that can transfer small fish while boiling them in a boiling tank, and near the exit of the transfer device, one end of a conveyor device that can take out the boiled small fish is arranged inclined in the boiling tank. In the continuous boiling device, a guide plate for guiding small fish extends from one end of the conveyor device toward the bottom of the boil tank, between the one end of the conveyor device and the guide plate. A continuous boiling device for small fish, characterized in that a partial heating section composed of a heat dissipating vibrator is provided near the bottom. Here, "each heat dissipation vibrator is oriented in the same direction as the screw conveyor" is not limited to the case where each heat dissipation vibrator is parallel to the axis of the screw conveyor, but also includes the case where it is slightly inclined.

〔Example〕

Embodiments of the present invention will be described in detail below based on the drawings.

In Figures 2 and 3, 8.10 is a boil tank;
Two screw conveyors 12 and 13 are arranged in parallel and driven to rotate in opposite directions via an electric motor 14 and a transmission mechanism (not shown). A packet conveyor 16 that supplies small fish into the boil tank 8, a first mesh conveyor 18, a second mesh conveyor 20, a third conveyor 22, etc. that take out and convey boiled small fish from the boil tank 10. It is equipped with

The boiling tank 8.10 has a bottom 24.2 as shown in FIG.
6 have a semicircular cross section, are connected to each other via a partition plate 28, and are communicated with each other through a communication port 30 provided in the partition plate 28, as shown in FIG.

In the boiling tank 8.10, as shown in FIGS. 1 and 4, a plurality of heat radiation pipes 32, 34, 36, 38 for passing heated steam are installed on the lower outside of the screw conveyor 12.13. The adjacent heat dissipation pipes are arranged so as to be located on concentric cylindrical surfaces with respect to the axis of the pipes 11 and 13, and are in contact with each other and are oriented in the same direction as the axis of the conveyor 12 and 13. Heat dissipation vibrator 32, 34, 36, 38 and bottom part 24 of boiling tank.
Spacers 40, 41, 42, 43 are arranged between the bottom 24, 26 and the bottom 24, 26 of the boiling tank to create a predetermined gap. This gap is said to be small enough for small fish to get bored. Also, screw conveyor 12.
13, there is no heat radiation pipe area 44 at the lower position of each axis.
．． 46 is formed.

As shown in FIG. 5, the heat dissipation vibrator 32 is connected between a steam inlet pipe 48 and a steam exhaust pipe 50, each of which has one end curved in an arc shape and whose tip is closed, and is fed from a bow A. The steam is discharged through the heat dissipation vibrator 32 from the base (B).

The heat dissipation vibrator 34, 36, and 38 are constructed in the same manner as above, and as shown in FIG.
4 to BO) D, from BO) E to boat F via heat dissipation vibrator 136, from boat G to BO) H via heat dissipation vibrator 38, and from each boat to heat dissipation vibrator 32, 34, 36. By passing steam through 38, water can be boiled in the boiling tank 8.10.

The small fish fed into the boil [8] by the first conveyor 18 are conveyed to the left in FIG. 13 to the right and sent out toward the exit, during which time the small fish are boiled.

In the boil tank 10, on the exit side of the screw conveyor 13 as a transfer device, there is a second
The conveyor 20 is arranged with one end thereof inclined,
Further, a guide plate 52 extending toward the bottom of the boiler W110 is provided at the tip thereof, and the guide plate 52 extends toward the bottom of the boiler W110.
The small fish sent out from the conveyor 20 are guided onto the second conveyor 20.

Further, at the bottom of the boiling tank 10, between the guide plate 52 and the screw conveyor 13, a partial heating section 54 having a predetermined extension is provided, which is made up of a heat radiation pipe, to increase the convection of hot water in the vicinity. The small fish sent from the screw conveyor 12 can be sufficiently spread.

Further, in front of the second conveyor 20 and below the guide plate 52, a partial heating section 56 configured in the same manner as the partial heating section 54 is provided near the bottom of the boiling tank 10 to prevent convection of hot water in the vicinity. They are trying to make it more popular. As a result, small fish on the second conveyor 20 are transferred to the next third conveyor 2.
2.Things that are not sent upward, but stick to themselves and return to the source,
Screw conveyor 121 [1
1.

Note that a water removal device (not shown) for removing water from boiled small fish is provided below the ts2 conveyor 20, and a drying fan (not shown) is provided above the third conveyor 22. . 58 and 60 are stirring plates attached to the screw conveyor 12, and 62 is a Java device for washing small fish before boiling.

In the above embodiment apparatus configured as described above, the small fishes supplied by the packet conveyor 16 are sent into the boil tank ε via the first conveyor 18, and further into the boil tank 10 by the screw conveyor 12. Here, the small fish are sent by a screw conveyor 13 toward a second conveyor 20 provided on the exit side, where the boiled small fish are taken out and dehydrated, and then a drying process is performed on a third conveyor 22. It is finished.

A partial heating section 54 is located near the 8 ports of the screw conveyor 13.
As a result, the convection of the hot water becomes more active, so that the small fish are well dispersed and placed evenly on the second conveyor 20. Therefore,
Dehydration treatment can be suitably performed.

Particularly when the guide plate 52 is widened at the end as in this embodiment, it is normal for small fish to not be placed uniformly on the mesh belt and tend to be uneven, but the partial heating section 54 diffuses the small fish in the water. Therefore, such inconvenience is eliminated.

In addition, some of the small fish transported by the second conveyor 20 are returned as they are, fall near the lower end of the second conveyor 20, and are deposited in that vicinity and rot. As a result of the increased convection caused by the heating section 56, the small fish are carried to one end of the boiling tank 8 along with the moisture leaking through the mesh of the second conveyor 20, and are returned to the boiling tank 8.1.
sent into 0. Therefore, small fish are prevented from settling and rotting. By the way, boil? ! A partial heating section 64 made of a heat dissipation pipe is also arranged in the -j1 section of F8, so that the small fish can be easily transported.

In the above example device, if the operation is stopped during use, small fish will remain in the boiling tank, but the small fish remaining between each heat radiation pipe and the bottom of the boiling tank and on each heat radiation pipe will be removed. It can be easily removed by running water through the area 44, 46 where there is no heat dissipation pipe. Therefore,
This eliminates the inconvenience of leftover small fish rotting.

In the above embodiment, the bottom of the boil tank is round, but instead of this, a boil 'WJ70.72 or the like having a shape as shown in FIGS. 7(a) and 7(b) may be used.

In short, any boil tank may be used as long as it has a shape in which the height of the bottom becomes lower toward the area where there is no heat dissipation pipe. In addition, if the operation of the example device is not to be stopped while small fish remain in the boil tank, it is necessary to stop providing a heat dissipation pipe-free area or to connect the heat dissipation pipe to the bottom of the boil tank. It is also possible to leave no gap between the openings. Furthermore, heat dissipation pipes 32, 34, 36.
Although 38 is arranged in the same direction as the screw conveyor, it is also possible to have a spiral shape or to provide it in the circumferential direction on the outer periphery of the screw conveyor. The number of heat dissipating vibrators is increased or decreased depending on the amount of heat dissipated, but if the number increases, it is also possible to position them above the axis of the screw conveyor.

Further, the heat dissipation pipes do not necessarily have to be brought into close contact with each other, and it is also possible to provide an appropriate PJ opening.

Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment in any way, and may be modified in various ways without departing from the gist of the present invention! ! Of course, it can be implemented in different ways.
