Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for boiling, steaming, and opening shrimp for sushi in a seafood processing plant.

Conventionally, devices for automatically boiling, steaming and opening shrimp are disclosed in Japanese Patent Application Laid-Open No. 57-79834 and Japanese Patent Application Laid-Open No. 56-12928.
This is known from Publication No. 7.

The former of these devices has a shrimp heating section, a cooling section,
The opening portions were arranged in sequence, and a shrimp transfer means was provided with shrimp receptors attached perpendicular to the direction of movement in each of these portions, and shrimp suppressors were attached to the heating portion and the cooling portion in accordance with the receptors. A shrimp holding conveyor is provided, and a pressing blade that is raised and lowered by a cylinder and pressing members located on both sides of the pressing blade are arranged in the opening.

Therefore, when the conveyor chain advances and the shrimp reaches just below the push-cutting blade, this is detected by a phototube, etc., and the cylinder is operated based on this detection signal, and the holding member suppresses the shrimp and the push-cutting blade removes the shrimp. Therefore, the above-mentioned detection means, a cylinder controller that operates based on this signal, and a device for temporarily stopping or decelerating the feeding means when the push-cutting blade makes the cut are necessary. Requires means.

For this reason, the equipment becomes complicated and expensive, and the raising and lowering of the lifting blade by the cylinder is likely to cause failure or damage to the equipment due to vibration. Because the process was either stopped or fed at a very low speed, work efficiency was low, and the daily throughput was limited to 50,000 fish. Also, with a device that uses a push-cutting blade, when the legs of a shrimp are placed on the belly, the legs are pressed onto the belly and cut together with the belly, so the legs are pushed into the cut in the belly and it is difficult to remove them. Not only was it time-consuming, but the push-cut method also had a messy cut.

Furthermore, when the shrimp is supported on a receiver perpendicular to the transport means and pressed by a shrimp holder fitted to the receiver, the shrimp holder applies rotational force to the shrimp to change the direction of the shrimp. There is a problem in that the shrimp are cut diagonally by the push-cutting blade, resulting in many defective products.

Next, the latter has a circular cutting blade connected to a drive wheel mounted in the center of the machine, and is equipped with a conveyor belt that holds the shrimp between rolls installed on both sides of the cutting blade. It consists of a bead-shaped open roll and a flat roll mounted on a shaft.

Therefore, even if shrimp whose bodies become thinner from the head to the tail are caught on a conveyor belt, the tail side swings from side to side and the body axis does not line up with the cutting blade, so two shrimp are placed on a skewer. The above-mentioned phenomenon must be prevented, and inserting and removing skewers requires a lot of manpower and time.

Shrimp, which are covered with a slippery shell and only come into contact with the conveyor belt at the thicker end of the head, cannot be conveyed with enough pressure to resist the cutting force unless pressure is applied to the shrimp to the extent that it is crushed.

If strong clamping pressure is applied to the shrimp as described above, the cutting blade will be tightened by the shrimp when cutting, so if the driving force of the cutting blade is weak, the cutting blade will stop, and if the driving force is strong, the shrimp will fall onto the conveyor. It gets thrown out of the belt and cannot be cut open.

When shrimp are transferred under pressure using a conveyor belt, the shrimp are stabilized with the flat ventral side down, so the incision is made from the dorsal side, which is the opposite of the original open shrimp that connects on the ventral side. Therefore, the product value is low.

Since there is no restraining member to press the shrimp with the ventral side down against the table, the shrimp is cut open with the warp in the middle and high, and the middle and high part is cut off, resulting in many defective products. There is a problem.

The present invention has been made in order to solve the above-mentioned problems, and by storing shrimp with their backs up in a receiver of a transfer means and pressing and attaching them to the receiver by a suppressing means and a suppressing member, By aligning the body axis with the rotary blade so that the water can flow stably, the shrimp can be boiled, steamed, and then belly-opened continuously and accurately.

The purpose is to provide processing equipment for Ehi. Next, an apparatus related to the present invention will be explained based on the drawings.

Figure 1 shows the entire apparatus, in which a heating section A, a cooling section B, and an opening section C are arranged in sequence, and the heating section A submergedly transfers shrimp into hot water in a hot water tank 1. The structure is such that the shrimp are boiled or steamed by passing them through the steam in the steaming chamber, and the cooling section B has a structure that cools the boiled and steamed shrimp by moving them submerged in cold water in water tank 2, and before that, pre-cooling. shower 3
It is preferable to provide

Reference numeral 4 denotes a chain conveyor-type shrimp transfer means that passes through the heating section A, the cooling section B, and the opening section C and returns under each section A, B, and C as shown in FIG. As shown in FIG. 3, transfer plates 5 are mounted at predetermined intervals and perpendicular to the direction of movement.

6 is a shrimp receptor, which is shaped like a gutter with a wider width on the head side and a narrower width on the tail side to match the shape of the shrimp a with its head, as shown in Figure 2 of the drawing. A large number of bodies 6 are attached to the transfer plate 5 in such a manner that their head sides face forward in the direction of movement of the four feeding means and their tail sides face rearward in the direction of movement.
As shown in the figure, it is parallel to the travel path of the transfer means 4.

Reference numeral 7 denotes a seven-chain conveyor type shrimp suppressing means provided above the transfer means 4 in the heating section A and the cooling section B, as shown in FIG. 1 of the drawings, and as shown in FIG. As shown, a hanging member 8 is provided in line with the transfer plate 5 of the transfer means 4, and a restraining rod 9 is swingably attached to this hanging member 8 as shown in FIGS. 3 and 4. Attach a shrimp suppressor 10 having a partially V-shape as shown in FIG. It is arranged to separate from the receiver 6 at the outlet of the cooling section B.

Reference numeral 11 denotes a rotating shaft provided above the transfer means 4 at right angles thereto as shown in FIGS. 1 and 5 in the above-mentioned opening C, and as shown in FIG. A rotary blade 12 is attached so that it coincides with the body axis of the shrimp a supported by the receiver 6 and its cutting edge is close to the bottom of the receiver 6, and the rotary blade 12 is attached to the feeding means as shown in FIG. 5 of the drawings. It is rotated by power in the direction of movement of step 4.

Reference numeral 13 denotes a cross member which is provided on the rear side of the rotating shaft 11 in the direction of movement of the transfer means 4 as shown in FIG. 6, a mounting bracket 14 for a restraining member, which will be described later, is suspended.

Reference numerals 15 and 15 are shrimp holding members attached to the mounting bracket 14 on both sides of the rotary blade 12 as shown in FIG. It is formed in a letter shape, and in the attached state shown in the figure, the shrimp A, which continuously passes through its lower part, is held down so that it is always pressed against the dorsal part 6 on both sides of the body axis. The continuous shrimp processing apparatus configured as described above operates the transfer means 4 to send the shrimp in an arc shape toward the abdomen in front of the heating section A to a large number of receivers 6 on the transfer plate 5 attached thereto. When the bent shrimp is fed with the belly facing upward, the suppressing means 7 approaches the transporting means 4 at the entrance of the heating section A,
Press the shrimp presser 10 onto the shrimp from directly above as shown in Figure 3 of the drawing. For this reason, the shrimp a are stretched straight in the supplied state, and transferred to the hot water tank 1 in boiling water by the movement of the transfer means 4, during which time they are boiled. The boiled shrimp a advances to the cooling section B, is pre-cooled by the shower 3, is transferred to the cold water of the water tank 2, is cooled, and reaches the outlet of the cooling section B when it does not bend even if the shrimp suppressor 10 is removed. . At this point, the restraining means 7 is raised away from the transfer means 4, and the shrimp restraining means 10 is moved away from the shrimp. Therefore, the shrimp a inside the receiver 6 advances to the opening C with its belly exposed, and when it approaches the rotary blade 12, the holding members 15, 15 hold down both sides of the body axis and receive the back part of the shrimp a. The shrimp is pressed against the body 6, and the rotary blade 12 cuts into the body axis to cut the shrimp a left and right, leaving a part of the dorsal side.
The cut shrimp a is sent to the rear of the opening C,
In order to fall into the product receptacle, there is a method that can continuously and automatically proceed with the operation of boiling the green shrimp while straightening the bend and opening the belly. In the apparatus according to the present invention, a shrimp heating part, a cooling part, and an opening part are sequentially arranged, and a gutter-shaped receiver for storing the shrimp with the belly facing upward is attached to each of these parts parallel to the direction of travel. Through the shrimp transfer means, a shrimp suppressor with a shrimp suppressor attached to the receiver of the transfer means is disposed in the heating part and the cooling part, and the opening part is provided with a shrimp suppressor attached to the shrimp body axis in the receiver. In addition, since the structure is provided with a rotary blade and a shrimp suppressor for pressing the shrimp against the receiver on both sides of the rotary blade, the shrimp supplied to the receiver of the transfer means are transferred to the heating section and the cooling section. , drain continuously at an opening and at a constant speed,
Because the steaming process can be performed, unlike conventional processing equipment in which the shrimp receiver and shrimp holder are installed perpendicular to the direction of movement of the transport means, a shrimp position detection means is installed in the opening, and this detection signal is sent to the shrimp processing device. There is no need for control means for the cylinders that operate based on the base, means for intermittent stopping or deceleration of the conveyor chain, etc. Therefore, the device is easily and inexpensively manufactured and does not generate vibrations. There is no risk of damage.

In particular, this device allows shrimp to flow through a stationary rotary blade and processes them continuously, so compared to conventional intermittent processing, this equipment can easily increase work efficiency by 2 to 3 times and reduce the daily throughput. 100,
000 to 150,000 fish, and even if the legs of the shrimp are located on the belly, these legs are cut off forward in the direction of movement of the shrimp and do not enter the cut of the shrimp, and therefore, This facilitates subsequent processing.

In addition, this device stores the shrimp with their bellies facing up in a gutter-like receiver and presses the shrimp against the receiver with a restraining member, so the body axis of the shrimp is naturally aligned with the rotating blade and does not change. There is no need to put two shrimp on a skewer, as is the case with conveyor belt transfer, and when cutting with a rotating blade, the shrimp do not clamp the rotating blade, making it possible to cut the shrimp reliably with just a small amount of power. In addition, the back of the shrimp pressed against the receptor by the holding member is held parallel to the lower peripheral edge of the rotary blade, and the back sides are connected with a constant uncut portion, so that no defective products are produced due to separation.

It has a unique effect.
