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 between the body and internal organs of a squid using a high-pressure water nozzle.

(Prior art) Conventionally, removing the internal organs of raw or thawed squid
This was done by the worker grasping the body of the squid with one hand and the leg side with the other and pulling.

(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. In addition, removing internal organs by pulling them out causes the internal pollutants and active substances to flow out, increasing the burden on wastewater treatment and not only increasing treatment costs. However, there were problems such as the utilization rate of the effective substance was drastically reduced, 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 using a high-pressure water nozzle, 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.

B. Structure of the Invention (Means for Solving the Problem) The means of the present invention to achieve the above object are as follows: (1) Fixing the squid so that the joint between its body and internal organs corresponds to a high-pressure water nozzle. A method for removing internal organs from a squid, in which the nozzle is inserted into the back side through an opening in the body, the joint is cut to separate the internal organs from the body, and the internal organs are removed by unfixing the body. (2) A method for removing viscera in which the high-pressure water nozzle according to claim 1 is used in cooperation with a cutter to facilitate initial cutting of the joint between the torso and the viscera.

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 adapted to the high-pressure water nozzle. 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 clamping pressure, and the body of the squid is straightened by the support rod, and since the support rod serves as a guide for the high-pressure water nozzle described later, the inside of the squid is By moving the nozzle forward and backward,
This has the convenience of allowing the nozzle to advance the joint without touching the trunk or internal organs, thereby reliably cutting only the joint.

However, the fixing means is not limited to those described above, and it goes without saying that other suitable means can be selected and used as long as the same function is achieved.

The purpose of the high-pressure water nozzle that cuts the joint between the torso and internal organs is to remove the internal organs from the torso by cutting through the joint and dividing it into upper and lower parts. A thin slit opening whose front end is wider than the joint,
As mentioned above, this high-pressure water nozzle can be used to spray water in the form of a film, and if both sides of the nozzle are engaged with the grooves provided inside the support rod and the grooves are moved forward and backward, the squid's body and internal organs can be sprayed. It is possible to cut only the joints without damaging the parts.

The cutter that cooperates with the high-pressure water nozzle is attached to the top or bottom of the high-pressure water nozzle so as to protrude beyond the tip of the nozzle, and is placed by making a cut in advance at the joint between the body and internal organs. By applying water pressure to the cut, the poor initial cutting performance of the nozzle type can be improved and the cutting speed can be increased.

(Function) In the squid viscera removal method of the present invention described above, when the support rods are inserted into the spaces created on both sides of the viscera in the body, the body is supported by the support rods, so that the squid viscera is removed above the body. The holding piece is lowered, and the holding piece and the support rod sandwich and fix the squid's body. After this, the squid's head is grabbed by the gripping member and the legs are also fixed, and the high-pressure water nozzle is attached to the squid's body. When the nozzle enters the interior through the opening of the body, it is guided by the support rod and cuts the joint between the torso and internal organs without touching them, separating the internal organs from the torso. By unfastening the head and removing it from the support rod, and 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.

Alternatively, a cutter is attached to the upper or lower part of the high-pressure water nozzle, and the cutter is made to cut into the joint between the body and the internal organs in advance of the nozzle, and the cutter directs high-pressure water to the cut place. If this action is applied, the initial cutting, which is difficult when using only high-pressure water, becomes easy, and the joint can be cut at a sufficient speed even when water pressure is used.

(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.
There are spaces 1, 1 on both sides of the body, so insert support rods 3, 3 with anti-slip unevenness 2 on the upper surface into these spaces 1, 1. Therefore, if the holding piece 4 is lowered onto the body part a in this state, the holding piece 4 and the support rods 3, 3 will be pressed together as shown in FIGS. 1 and 2. Therefore, the support rods 3,
As shown in FIG.
It entered the back side through the opening. Then, the high-pressure water nozzle 6 is guided by the guide grooves 5, 5, and without touching the torso a or the internal organs b, the high-pressure water nozzle 6 is guided to the joint c between the torso a and the internal organs b.
To separate the internal organs b from the body part a, at this time, raise the holding piece 4 to release the fixation of the body part a, remove the tip side of the body part a, and let it be grasped by the member 7 and pull it. Then, when the body part a is removed from the support rods 3 and 3 and dropped downward, the gripping member 8 that grips the head d is opened, the leg part e is separated from the body part a along with the separated internal organs b. Since it fell to a different position and was separated from body part a, the work of removing internal organs b from body part a was carried out automatically and efficiently, and there was no damage to the internal organs.

Furthermore, if a cutter 9 is attached to the upper part (or lower part) of the high-pressure water nozzle 6 as shown in the drawings, this cutter 9 precedes the high-pressure water nozzle 6 and cuts the body part a and the internal organs. An incision was made at the junction c with b, and the initial cutting, which is difficult with water pressure, was easily made, and the water pressure made the cutting happen quickly.

C. Effects of the Invention The method of the present invention involves fixing the squid, cutting the joint between the body and internal organs using a high-pressure water nozzle, separating the internal organs from the body, and removing them. By using a device that circulates the ingredients and high-pressure water nozzles by arranging them in a turret type or conveyor type, it is possible to easily increase the efficiency by more than three times compared to the conventional manual extraction of internal organs. Even if the fixing is done manually, only a small amount of labor is required, so the processing cost can be reduced to about a fraction of the conventional cost.

Removal of the internal organs by cutting the joint between the body and internal organs using a high-pressure water nozzle requires a short time, so there is little loss of freshness of the squid during processing. Bacterial contamination is also suppressed, which is effective in maintaining the quality of the product, and the jet water from the nozzle is effective in cleaning the torso and internal organs by effectively washing them.

When removing internal organs using a high-pressure water nozzle, the joint between the torso and internal organs is cut, the internal organs are removed without being torn into pieces, unlike traditional methods of removing internal organs by pulling them out manually. Not only can effective substances such as ink be recovered without waste, but the pollutants that are subject to wastewater treatment can be treated all at once without being dispersed, reducing the burden of wastewater treatment and reducing treatment costs. can save significantly.

When a cutter is placed in parallel with the high-pressure water nozzle, the cutter can easily perform the initial cutting of the joint, which is difficult to do with water pressure, and the nozzle can cut the joint without delay.

It has the following unique effects.
