Description

[Detailed description of the invention] This invention relates to a device for taking out materials to be boiled in a continuous boiling device for small fish.

The inventor of the present invention first formed a circulation flow path in a certain direction in the boiling tank, placed a device for charging materials to be boiled at an appropriate position above the circulation flow path, and At an appropriate location in the circulation channel, a device for taking out materials to be boiled is arranged, which consists of a series of mesh belt conveyors whose starting end is submerged in the liquid medium of the circulation channel, and whose terminal end is raised and guided out of the boiling tank. We have developed a continuous boiling device for small fish.

In this continuous boiling device, the raw small fishes are continuously fed in a fixed amount by the feeding device into the proper place of the circulation channel, and are boiled while being made to flow along the circulation channel. However, since the boiled small fish can be continuously taken out by the above-mentioned take-out device, small fish can be boiled very efficiently. If processing continues for more than a certain period of time, the liquid medium in the boiling tank will gradually become contaminated due to the colloid, fat, and scum exuding from the small fish, so the fish must be removed from the boiling tank. These impurities become resistant to adhesion to the surface of small fish.

Therefore, if small fish boiled in such a boiling tank are dried, the surface of the product will be matte and the quality will inevitably be poor.

Of course, if such a situation occurs, all you have to do is replace the water in the boiling tank with fresh water, but this kind of boiling process for small fish should be done as quickly as possible before the freshness of the harvested small fish decreases. It is desirable to complete the boiling process quickly, and if the water in the boiling tank is replaced, the boiling process has to be temporarily interrupted, and during that time, the freshness decreases, which reduces the yield of small fish. In cases where there is a large amount of hot water, the boiling process is continued continuously in the polluted hot water cabinet to avoid deterioration of the product due to a decrease in freshness due to interruption of the boiling process rather than deterioration of quality due to contamination of the hot water. The reality is that I went to

In view of the above-mentioned circumstances, this idea was developed to ensure that high-quality products can be obtained even if continuous boiling is performed for a long time without replacing the water in the boiling tank in batches.
In the continuous boiling device as described above, a shower device is installed above a portion Q where the mesh belt conveyor is exposed in the liquid medium of the boiling tank by positioning it in an upper direction near the starting end of the above-mentioned take-out device. In addition, the present invention attempts to provide a device for taking out materials to be boiled that is devised so that cleaning by the shower device can be carried out more effectively.

To explain the embodiment with reference to the drawings, in the drawing, 1 is a boiling tank for materials to be boiled, and this boiling tank 1 has a circulation flow path 3 formed in a zigzag shape with a partition wall 2. The liquid medium (that is, salt water with an appropriate concentration) in the tank 1 is circulated and flowed in the direction of the arrow by a pump device 4 disposed at an appropriate location. The liquid medium in the tank 1 is heated to an appropriate temperature by a steam pipe 5 submerged in the tank bottom 1a and a hot steam vibro placed along the partition wall 2.

The boiling material, which has been washed and drained, and the raw small fish are fed into the boiling tank 1 by the feeding conveyor 7, which constitutes the feeding device for the boiling material, into the circulation flow path 3, which is fed to the pump device. The raw small fish thrown into the boiling tank 1 are continuously fed into a fixed amount at a position A near the outlet 4a of the boiling tank 1. The material to be boiled consists of a series of mesh belt conveyors 8 in which the starting end 8a is sunk when the material is boiled while flowing along with the liquid flow and reaches a position B near the suction side of the pump device 4. In this embodiment, the mesh belt conveyor 8 is taken out from the boiling tank 1 by the tip of a support frame 9 that extends from the boiling tank 1. Two left and right pairs of front and rear sprocket wheels 12.13 are pivoted on a V-shaped conveyor frame 11 supported by a pivot 10, and a pair of left and right chains 714.14 are suspended from the sprocket wheels 12.13, respectively. , is constructed by stretching a series of mesh belts 15 that are much wider than the width of the circulation flow path 3.

Also, part B of the circulation channel 3 of the boiling tank 1 in which the starting end 8a of the mesh belt conveyor 8 configured in this way is submerged.
The mesh belt conveyor 8 is made wider than other parts of the circulation flow path 3 to match the width of the mesh belt conveyor 8, and its tank bottom 1b is deeper than the other tank bottom 1a. It is formed into an inclined surface along the lower surface, and a portion C in front of the above-mentioned portion B of the circulation flow path 3 is slightly enlarged than the other portions of the circulation flow path 3, so that this portion C and the above-mentioned portion B A section connecting the two is formed to expand in the direction of section B, and an inclined plate 16 facing toward the upper surface of the tip 8a of the mesh belt conveyor 8 is disposed on the tank bottom 1a of this section. ing.

In addition, 17 and 18 are guide rollers of the chino 14, and 19 is an overflow port opened in the tank bottom 1b of the B section of the circulation channel 3, and this overflow port 19 has an adjustment gate that can adjust the overflow height. 20 is arranged so that the liquid level height in the boiling tank 1 can be freely adjusted.

In the B portion of the circulation flow path 3, the mesh belt 15 is positioned between the upper and lower mesh belts 15 and 15 of the starting end 8a of the mesh belt conveyor 8 submerged in the liquid medium, so that the width of the mesh belt 15 is approximately the width of the mesh belt 15 in the width direction. - A suction duct 23 is provided which has a suction port 21 which is opened to the outside and whose discharge port 22 side is connected to the suction side of the pump device 4. The liquid medium passes through the mesh belt 15 above the mesh belt conveyor 8 and is circulated in the direction of the arrow.

That is, the boiled small fish taken out from the boiling tank 1 by the mesh belt conveyor 8 must be prepared in such a way that the mesh belt 15 is much wider than that in the circulation flow path, and that the starting end 8a of the mesh belt conveyor 8 is The front circulation flow path part B is placed on the mesh belt 1 from the other circulation flow path 3 parts.
5, and the suction port 21 of the suction duct 23 is opened approximately along the width of the mesh belt 15 in the width direction of the mesh belt 15. - The boiling water taken out from tank 1 in this way is placed in a state with extremely high cooling efficiency and transported out of tank 1. According to this invention, a shower device 25 for washing the finished small fish is installed at the starting end 8a of the mesh belt conveyor 8.
The mesh belt conveyor 8 is disposed above the portion of the boiling tank 1 exposed from the liquid medium.

That is, in this embodiment, the shower device 2
5 are arranged in an appropriate number in parallel along the width direction of the mesh belt 15 above the portion of the mesh belt 15 exposed from the liquid medium above the boiling tank 1 and above the mesh belt conveyor 8. It is composed of a group of pipes 27 with a large number of through holes 26 drilled in a section corresponding to the width of the mesh belt 15 on the lower surface side, and each pipe 27 is connected to a washing liquid supply device (not shown). Washing hot water containing the same concentration of salt as the liquid medium in the boiling tank 1 is supplied at extremely low pressure, and therefore flows from the through hole 26 of the pipe 27 onto the upper surface of the mesh belt conveyor 8. The washing hot water containing salt is dripped over its width.

Note that the jetting power of the cleaning hot water from the pipe 27 is set to such an extent that the small fish on the mesh belt conveyor 8 are not scattered or flowed down by the jetting. Alternatively, the mesh belt conveyor 8 may be provided at a portion where the upper surface of the mesh belt conveyor 8 is guided in the horizontal direction.

Further, in this embodiment, the following dewatering device and reversing device are disposed along the conveyance path of the mesh belt conveyor 8 together with a cooling device.

That is, as shown in FIG. 2, 29 is a suction box that has a seal plate 30 in sliding contact with the lower surface of the upper mesh belt 15 and is located between the upper and lower mesh belts [5 and 15]. has a suction slit 31 formed on its upper surface, and this suction slit 31 is brought close to the lower surface of the mesh belt 15 and connected to a vacuum suction device (not shown) via a duct.

Futa 32 is a wind box of an air blower installed between the upper and lower mesh belts 15 and 15, and this wind box 32 has an upward outlet 33 formed on its upper surface, which is connected to the duct. via a compressed air source (not shown).

Further, 34 is located above this mesh belt conveyor 8.
In order to avoid at least the upper part of the air blower, in this embodiment, the downward-facing electric fans 35 are placed above the suction box 29 on both sides of the mesh belt conveyor 8 above the air blower. This is a partition wall that is placed upright to prevent small fish on the mesh belt conveyor 8 from spilling to the side of the mesh belt conveyor 8 when the small fish on the mesh belt conveyor 8 are blown up and turned over by the air blow device. .

The button 36 has a downward air outlet 36a disposed near the terminal end 8b of the mesh belt conveyor 8 between the top and bottom of the mesh belt 15 constituting the mesh belt conveyor 8. With low equipment,
This is to ensure that the small fish transported at the terminal end 8bt of the mesh belt conveyor 8 fall without being left attached to the belt conveyor 8.

3T is a drying device in which the starting end of the belt conveyor 38 is housed below the ending end 8b of the mesh belt conveyor 8.

The device for taking out materials to be boiled according to this invention is constructed as described above, and its operation will be explained with reference to the above embodiment.
Therefore, the small fish that are thrown into the circulation channel 3 of the boiling tank 1 and boiled while flowing through the circulation channel 3 are transported to the starting end 8a of the mesh belt conveyor 8, which constitutes a device for taking out materials to be boiled. When the liquid reaches the mesh belt conveyor 8, it is scooped up onto the mesh belt conveyor 8 and carried out of the boiling tank 1. B is much wider than the width of the circulation channel 3, and the portion of the circulation channel 3 reaching the starting end 8a of the mesh belt conveyor 8 is made to match the width of the conveyor 8. The suction port 2 of the suction duct 23 is enlarged and connected to the pump device 4.
1 is opened to approximately the width of the mesh belt conveyor 8, and the liquid medium to be fed into the circulation flow path 3 is spread through the flow path at the portion B, and the mesh belt conveyor When the mesh belt 15 on the upper side of 8 is buttoned in the width direction, the fish can be uniformly passed through and circulated. It is gradually diffused in the section B and flows into the section B, where it is uniformly diffused almost throughout the flow path, and there, it is deposited almost uniformly over its width on the mesh belt 15 above the starting end 8a of the mesh belt conveyor 8. It will be scooped up in a spread out state and carried out of the shaving tank 1.

The boiled small fish thus placed on the mesh belt conveyor 8 and taken out of the liquid medium in the boiling tank 1 are transported to 25 shower devices disposed above the boiling tank 1. Impurities such as dirt adhering to the surface of the fish are completely washed away by the washing warm water dripping from the pipe 27, and the fish meat is sufficiently dehydrated and cooled by the dewatering device and the cooling device to tighten the fish meat, and then transferred to the mesh belt conveyor 8. The next step starts from the terminal end 8b.

In this embodiment, the hot water used to wash small fish passes through the mesh belt conveyor 8 and falls into the boiling tank 1. The increased amount of liquid medium is caused to overflow from the overflow port 19 cut out from the tank bottom 1bKB in the B section of the circulation channel 3, and the liquid level in the tank 1 is always maintained at a constant level. .

In the above embodiment, the shower device 25 is disposed above the portion of the boiling tank 1 where the mesh belt conveyor 8 is exposed from the liquid medium and above the boiling tank 1. 25, hot water of the same quality as the liquid medium in the boiling tank 1 is dripped onto the boiled small fish placed on the mesh belt conveyor 8 to wash the small fish. Although an example has been shown in which the hot water is returned to the boiling tank 1, the shower device in the takeout device of this invention is not limited to the above embodiment, and other embodiments may be used. , the shower device 25 may be arranged above the boiling tank 1 to drip cold water onto the small fish on the mesh belt conveyor 8. With this configuration, the shower device 25 In addition to the cleaning effect of the boiled small fish, a cooling effect can also be obtained.In another embodiment, the small fish can be washed by the mesh belt conveyor 8 outside the liquid medium of the boiling tank 1. A hot water shower device and a cold water shower device may be installed in parallel, located before and after the conveyance path.

In any case, as is clear from the above explanation, the device for taking out materials to be boiled according to the present invention is particularly designed to be located above the starting end of the mesh belt conveyor, and to be installed in the shower 7jK above the mesh belt conveyor. A device is provided, and the shower device is configured so that boiled small fish that have just been taken out from the boiling tank and placed on the mesh belt conveyor can be washed well. Therefore, as mentioned at the beginning, the liquid medium in the boiling tank becomes contaminated due to long-term continuous use, and as a result, impurities such as sludge adhere to the boiled small fish taken out from the boiling tank. This can also be reliably washed and removed by the shower device, and in the device of this invention, the width of the mesh belt conveyor on which the shower device operates, and the circulation flow path for materials to be boiled in the boiling tank are reduced. The material to be boiled, which is configured to be larger than the width of the boiling tank and which is boiled while flowing in the boiling tank, is dispersed by the action of the suction duct, which is arranged between the upper and lower mesh belts. The cleaning effect of the Java ← device is very good because it is scooped onto the mesh belt conveyor.

Therefore, according to the take-out device of this invention, continuous boiling operation can be performed for a long period of time without having to replace the liquid medium in the boiling tank batchwise, and therefore without causing a drop in the freshness of small fish due to interruption of the boiling process. Even if you do this, you can still get a good quality product.
