Description

Detailed Description of the Invention A. Purpose of the Invention (Field of Industrial Application) The present invention is a squid evisceration method used in the seafood processing industry. Specifically, the present invention relates to a method for easily and quickly removing the internal organs without damage by cutting the joint where the body and internal organs of a squid are joined with a knife.

(Prior Art) Conventionally, the removal of the internal organs of a squid that is raw or thawed has been carried out by an operator grasping the body side of the squid with one hand and the leg side with the other hand and pulling the squid.

(Problem to be solved by the invention) When removing the internal organs of a squid by manually pulling out the squid as described above, a large number of workers are required, making it difficult to secure them and incurring a large amount of daily labor costs. Therefore, the treatment cost is high, and when the internal organs are removed by pulling out, the internal pollutants and effective substances are torn into pieces and the internal pollutants and effective substances flow out, which increases the burden of wastewater treatment and not only increases the treatment cost. There were problems such as the utilization rate of effective substances was drastically reduced and it was uneconomical.

The present invention was made to solve the above-mentioned conventional problems, and by cutting the joint between the squid's body and internal organs with a knife, the internal organs can be automatically removed from the squid's body without damage. The purpose of the present invention is to provide a method for removing the internal organs of squid that can be carried out efficiently and efficiently.

B. Structure of the Invention (Means for Solving the Problems) The means of the present invention to achieve the above object are as follows: (1) A squid is fixed so that the joint between its body and internal organs corresponds to a cutter. , a squid viscera removal method in which the cutler is advanced through the opening of the body to the back side, the joint is cut to separate the internal organs from the body, and the body is then unfixed to remove the internal organs; (2) cooperating a water injection means with the cutter according to claim 1;
The method consists in removing the internal organs of a squid and cleaning the trunk and internal organs.

The means for fixing the squid used in this method are:
This is for the purpose of supporting the squid so that it does not move when the joint between the body and internal organs is aligned with a knife. After inserting the supporting rod, a holding piece is lowered onto the body, and if a fixing means is adopted in which the holding piece and the supporting rod sandwich the body, the squid is securely fixed by the clamping pressure. Moreover, the support rod straightens the body of the squid, and the support rod acts as a guide for the cutlery described later, and by moving the cutter forward and backward inside the support rod, it is possible to touch the cuttlefish's body and internal organs. This method has the convenience of being able to securely cut only the joint by cutting into the joint without cutting, but fixing is not limited to this method, and the same function can be achieved. Any other suitable means may be selected and used.

The purpose of the knife that cuts the joint between the torso and internal organs is to remove the internal organs from the torso by cutting into the above-mentioned joint and dividing it into upper and lower parts. It uses a thin plate with a blade only on the edge, and if the tip is shaped like a concave arc or a valley, it can prevent the joint from escaping to the outside and ensure a secure cut.
As described above, this knife is engaged with the groove provided inside the support rod, and by moving the groove forward and backward, it is possible to cut only the joint without damaging the trunk or internal organs of the squid.

The water injection means that cooperates with the knife is attached to the lower part of the knife, and when the knife cuts into the joint between the body and internal organs, water is blown into the body while moving along with the water, thereby damaging the body and internal organs. It is desirable to provide a pair of cleaning devices to sandwich the joint.

(Function) In the squid viscera removal method of the present invention described above, when the support rod is inserted into the space created on both sides of the viscera in the body, the body is supported by the support rod, so that the squid viscera is removed above the body. After lowering the holding piece and fixing the body by sandwiching it between the holding piece and the support rod, the head of the squid is also grabbed by the gripping member and the legs are also fixed, and then the cutter is placed on the body of the squid. When inserted deep through the opening, the knife is guided by the support rod and cuts the joint between the torso and internal organs without touching the torso or internal organs, separating the internal organs from the torso. By unfastening the torso and removing it from the support rod, then opening the head gripping member and removing the leg side, it is possible to distinguish between the legs with internal organs and the torso.

Additionally, a water injection means is provided at the bottom of the cutlery,
By blowing out washing water from this means into the body as the knife advances, the body and internal organs can be washed and cleaned in parallel with the removal of internal organs.

(Example) An example of the squid viscera removal method according to the present invention will be described below with reference to the drawings.

When you hold a raw or thawed squid with its dorsal side facing up, the internal organs b can be seen inside the torso a, as shown in Figure 1.
Spaces 1, 1 are created on both sides of the body, so when support rods 3, 3 with anti-slip unevenness 2 formed on the upper surface are inserted into these spaces 1, 1, the body part a is supported by the support rods 3, 3. Therefore, if the presser piece 4 is lowered onto the body part a in this state, the body part a will be as shown in FIGS. 1 and 2.
As shown in the figure, since the holding piece 4 and the support rods 3, 3 are clamped and fixed, the guide grooves 5, 5 correspondingly provided on the inner sides of the support rods 3, 3 described above are engaged. The mating plate-shaped cutter 6 was inserted into the back side through the opening of the body part a, as shown in FIG. Then, the knife 6 is guided and engaged with the guide grooves 5, 5, so it cuts the joint c between the body part a and the internal organs b without touching the body part a or the internal organs b, and cuts the internal organs b. Since it will be separated from the body part a, at this time, the holding piece 4 is raised to release the fixation of the body part a, and the tip side of the body part a is removed and grabbed by the member 7 and pulled, and the body part a is attached to the support rod 3. , 3 and drop it downward. Next, when the gripping member 8 that grips the head d is opened, the leg e falls together with the separated internal organs b to a different position from the torso a, and the torso a Therefore, the work of removing internal organs b from torso part a was carried out automatically and efficiently, and there was no damage to the internal organs.

Furthermore, if a water injection means 9 is provided at the bottom of the cutter 6 as shown in each figure in the drawings, the cutter 6 will enter the inner part through the opening of the body a and the joint c between the body a and the internal organs b. As the body was being cut, water was blown out to the inside of the body part a, so that the body part a and the internal organs b could be washed in parallel with the removal of the internal organs by the knife 6.

C. Effects of the Invention In the method of the present invention, the squid is fixed and a cutter is cut into the joint between the body and internal organs to separate the body and internal organs and remove the internal organs. If you use a device that arranges squid and cutlery in a turret type or conveyor type and circulates them, you can easily increase the efficiency by more than three times compared to the conventional manual extraction of internal organs. Even if the process is carried out, the required labor cost is small, so the processing cost can be reduced to about a fraction of that of the conventional method.

This method of removing viscera takes less time, so there is less loss of freshness during processing, and since there are fewer opportunities for human intervention or exposure to the outside air, bacterial contamination is suppressed, and it is effective for maintaining product quality. .

When removing the internal organs by cutting the joint between the torso and internal organs with a knife, the internal organs are taken out as is without being torn into pieces, so effective substances such as squid ink, which is used as a raw material for liquid crystals, are wasted. Not only can the pollutants that are the target of wastewater treatment be collected without being dispersed, but they can be treated all at once without being dispersed, which can reduce the burden of wastewater treatment and significantly reduce treatment costs.

If a water injection means is installed in parallel with the cutlery, the torso and internal organs can be washed and cleaned at the same time as removing the internal organs.

It has the following unique effects.
