BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous boiling apparatus for small fishes.

[0002]

2. Description of the Related Art An apparatus for continuously boiling small fish is disclosed in Japanese Utility Model Publication No. 56-39471. In this method, the inside of the boiling tank is partitioned by a partition wall, a circulation channel in a certain direction is formed in the boiling tank, and a device for feeding a substance to be boiled is provided above the circulation channel. Via the circulation channel, the boiled matter is taken out to the outside by a mesh belt conveyor, and the circulating liquid medium is recirculated by a pump device.As a heating method, an inter-heating pipe is provided in the partition, and the partition is used as a heat exchanger. I have. In this method, the heat pipe and the partition are connected to each other and further fixed to the bottom of the boiling tank. Therefore, the partition is easily cracked due to expansion and contraction due to a temperature change of the heat pipe, and the life of the boiling tank is extended. It was short.

[0003] Further, since the heat pipe and the heat exchanging section are on the side of the flow path, when the flow rate of the boiled substance in the flow path is high,
In some cases, the temperature of the central portion of the boiled product did not rise sufficiently, resulting in uneven cooking. Further, when steam is directly discharged into the flow path, the boiled substance may be damaged by a sudden change in temperature and impact by the steam.

[0004]

An object of the present invention is to provide an automatic boiling apparatus provided with a heating tube capable of solving the above-mentioned problem of having a short life and uniform heating of a flow path. It is in.

[0005]

In order to solve the above-mentioned problems, in the present invention, a heating pipe is provided at the center of the flow path or below the center, and the heating pipe has a double structure, A plurality of small holes are provided in the tube, and a plurality of small holes are provided in the boiling tank surface of the outer tube. Steam is directly passed through the inner tube and is ejected from the small holes, thereby heating the outer tube as well as the liquid medium inside the outer tube.

[0006]

With the heating tube having a double structure, the liquid medium existing between the inner tube and the outer tube is further heated by the heat transfer from inside the inner tube and the steam ejected from the small holes of the inner tube. Reduce the temperature on the outer surface of the tube. The liquid medium heated in the heating tube is discharged from the small hole of the outer tube with an increase in the internal pressure of the tube, and the liquid medium in the flow path is guided to the heating tube by the pressure reduction by the discharge, and is heated in the heating tube. By this process, part of the liquid medium circulates outside the heating tube and inside the heating tube through the small hole of the outer tube, and the liquid medium released from the heat transfer tube hits the bottom of the boiling tank, along with heat transfer convection due to heat of the heating tube. In addition, a convection is formed on the liquid medium surface of the flow path, the temperature of the entire flow path is made uniform, and the boiled substance existing at the bottom of the flow path is lifted up, thereby causing the action of stirring the boiled substance in the flow path. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of an embodiment of the present invention. As shown in FIG. 1, the boiling pot (1) is provided with a plurality of partition walls (3), forms a plurality of rows of linear flow paths (2), and has a semicircular shape between the flow paths. , A zigzag-shaped flow path is formed, a discharge port (5) from the pump device is provided at one end of the flow path, and the other end is introduced into a conveyer (13) for taking out the boiled substance. And In the flow path where the pump device discharge port (5) exists, a device for charging the boiled substance is provided. Introduction section of take-out conveyor (13)
Is provided with a space for installing a take-out conveyor (6), and further provided with a pump device inlet (14), and the circulating liquid medium is supplied from the pump device inlet (14) by the pump device (5) to the pump device outlet. It is conveyed to (15) and forms a circulation path.

As shown in FIGS. 2 and 3, a heating pipe (4) is provided at the center or below the center of the flow path, and each heating pipe (4) is connected via a steam flow control valve (7). And connected to the steam pipe (8). As shown in FIG. 4, the heating tube is formed of an outer tube portion (9) and an inner tube portion (10).
0) is connected to a steam pipe. A plurality of outer tube holes (11) are provided on the outer tube portion (9) toward the bottom of the boiling tank, and further,
A plurality of outer tube holes (12) are provided in the inner tube portion. FIG. 5 and FIG. 6 are views showing the state of convection of the liquid medium around the heat transfer tube (4) in the flow path. FIG. 5 is an explanatory diagram in the case where the small holes of the inner tube are provided in the same direction as the outer tube, and the convection is formed symmetrically to the left and right. FIG. 6 is an explanatory diagram of the convection state of the liquid medium when the position of the inner tube hole (12) is provided on the partition wall side. By appropriately providing the position of the inner tube hole (12) and the position of the small hole of the outer tube depending on the position of the flow path, the bent portion of the flow path
The driving force in the bending direction can be obtained.

[0009]

[Effects of the Invention] By the implementation of the present invention, the heated liquid medium is discharged from the small hole at the bottom of the heat transfer tube without the steam directly hitting the boiled substance by the double tube at the center of the flow path. By the convection of the liquid medium generated by the heating by the heat transfer tube, the boiled substance in the flow path is appropriately stirred, and the temperature becomes more uniform, and a boiled substance with less boiling is obtained.
