Abstract

PURPOSE:To simply and rapidly remove internal organs without damaging cuttlefish by fixing cuttlefish, introducing a knife into a joint part of trunk and internal organs, separating the trunk from the internal organs and removing the internal organs. CONSTITUTION:For example, two supporting levers are inserted into space occurring between trunk and internal organs of cuttlefish, a suppressing piece is dropped to the top of the trunk and the cuttlefish is immobilized by a fixing means of sandwiching the trunk by the suppressing piece and the supporting lever in such a way that the joint part of the trunk and the internal organs corresponds to a knife. Then the knife, for example, is introduced from the opening of the trunk to the interior by guide of the supporting lever, the joint part of the trunk and the internal organs is cut without bringing the knife into contact with the trunk and the internal organs to separate the trunk from the internal organs. Then the fixing of the trunk is released, the internal organs are removed and optionally removal of the internal organs and washing of the trunk and the internal organs are simultaneously carried out by cooperation of the knife and a water spraying means.

Description

DETAILED DESCRIPTION OF THE INVENTION A1.Object of the invention (industrial application field) 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 internal organs from raw or thawed squid was 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, which is difficult to secure, and a large amount of labor costs are incurred on a daily basis. The cost of licking is high, and removing the internal organs by pulling them out causes the internal pollutants and effective substances to flow out, which increases the burden on wastewater treatment and increases treatment costs. There were problems such as the utilization rate of the effective substance was reduced to a large [↑J], making it 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 removed from the squid's body without damage.
The purpose of the present invention is to provide a method for automatically and efficiently removing the internal organs of a squid.

B1 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 cutlery. A method for removing viscera from a squid, in which the cutler is advanced to the inner side through an opening in the body, 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 is for the purpose of supporting the squid so that it does not move while the joint between the body and internal organs is aligned with the cutter. After inserting two support rods into the space between the body and the internal organs, a holding piece is lowered onto the body, and the body is held between the holding pieces and the support rod. Then, the squid is securely fixed by the pinching pressure, and the body of the squid is straightened by the support rod, and the support rod acts as a guide for the cutlery described later, allowing the cutter to move forward and backward inside the support rod. This method has the convenience of allowing the knife to cut into the joint without touching the torso or internal organs, thereby ensuring that only the joint is cut. The present invention is not limited to this, and any other suitable lower stage can be selected and used as long as the same function is achieved.

The blade 1 for cutting the joint between the torso and internal organs is a blade designed to remove the internal organs from the torso by cutting into the above-mentioned joint and dividing it into upper and lower parts.
In other words, it uses a thin plate with a blade only on the front edge in the direction of travel, 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 mentioned above, this knife is engaged with a lever provided inside the support rod, and by moving this lever forward and backward, it is possible to cut only the joint without damaging the body or internal organs of the squid.

The water injection means that cooperates with the cutter is attached to the bottom of the cutter,
When the knife cuts into the joint between the torso and internal organs, water is blown into the torso while moving along with the cut, thereby washing the torso and internal organs.It is preferable to provide a pair so as to sandwich the joint. be.

(Function) In the squid viscera removal method of the present invention, which is not marked ``Off'', 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. After lowering the presser piece upward and fixing the body by sandwiching it between the presser piece and the support rod, the head of the squid is also gripped by the gripping member and the shoulder side is also fixed, and then the cutler is attached to the body. When the knife enters the interior through the opening of the body, it is guided by the support rod and cuts the joint between the body and internal organs without touching the body or internal organs, separating the internal organs from the body. At this time, by unfastening the torso and removing it from the support rod, then opening the head gripping member and removing the shoulder side, it is possible to distinguish between the legs with internal organs and the torso. .

Furthermore, if a water injection means is provided at the bottom of the cutlery and this means blows out washing water into the body as the knife advances, the body and internal organs are washed in parallel with the removal of the internal organs, and these can be put on the market. It is something that can be made beautiful.

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

If you hold raw squid or thawed squid with the dorsal side facing 42,
As shown in FIG. 1, there are spaces 1, 1 on both sides of the internal tray inside the body part a, and a support rod 3. ．． If you insert 3,
Since the body part a is supported by the support rods 3, 3, if the presser piece 4 is lowered onto the body part a in this state, the body part a will be moved to the first position.
As shown in FIG.
A plate-shaped cutter 6, which engages with guide grooves 5, 5 correspondingly provided on the inside of the body 3, was inserted into the rear side through the opening of the body part a, as shown in FIG. Then, the cutter 6 is guided and engaged with the guide grooves 5, 5, so that the cutter 6 is inserted into the body a and inside! Cut the joint C between the body part a and the viscera without touching the &ib, and separate the viscera from the body part a. At this time, raise the holding piece 4 to fix the body part a. Undo it, let the distal end of the body part a be gripped by the removal member 7 and pull it, remove the body part a from the support rods 3, 3 and drop it down, then open the grip member 8 that grips the head d. , together with the separated internal organs, leg e falls to a different position from torso a and is separated from torso a, so torso a
The work of removing 1ib from the body was carried out automatically and efficiently, and there was no damage to the internal organs.

Furthermore, if water injection means 9 is provided at the lower part of the cutter 6 as shown in each figure in the drawings, the cutter 6 enters the inner part through the opening of the body a and the joint C between the body a and the internal organs. As the body is being cut, water is blown out to the inside of the body part a, and the body part a and the internal organs cannot be washed in parallel with the removal of the internal organs by the knife 6.

C1 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. By using a device that arranges the tools and cutlery in a turret type or conveyor type and circulates them, it is possible to easily increase the efficiency by more than three times compared to the conventional manual extraction of internal organs, and it is possible to fix the squid easily. Even if it is performed manually, the required labor cost is small, so the processing cost can be reduced to about a fraction of the conventional cost.

This method of removing internal organs does not require much time, so there is little loss of freshness during processing, and since there is little chance of human intervention or exposure to the outside air, bacterial contamination is suppressed, and it is effective for preserving product quality. be.

When the joint between the torso and the internal organs is cut with a knife and the internal organs are removed, the internal organs are recovered as is without being torn into pieces, so they can be used, for example, as squid ink, which is used as a raw material for liquid crystals.

Not only can effective substances be recovered without waste, but
Since pollutants to be treated in wastewater can be treated all at once without being dispersed, the burden of wastewater treatment can be reduced and treatment costs can be significantly reduced.

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.
