Description

  The present invention relates to a sea urchin processing apparatus and a sea urchin processing method for making a hole in a sea urchin shell, removing internal organs and the like, and collecting a woundless gonad.

  A common sea urchin treatment method is to first divide a sea urchin shell into two parts, shake off the internal organs, etc., and then peel off the gonad attached to the shell with a special spoon. This method has a disadvantage that one or two of the five gonads that always hit the crack are damaged. In addition, it is difficult to remove the remaining gonads without damaging them, and it is considered a craftsmanship that requires the season. Furthermore, since the shell divided into two is not useful, it is discarded as it is.

  Japanese Laid-Open Patent Publication No. 56-99744 (Patent Document 1) shows a sea urchin shell splitter. According to the patent document 1, with the tip of the suppression member engaged with one side of the sea urchin's mouth, the shell blade is broken into the sea urchin and split open to split the sea urchin shell into two to collect the gonads. Has been shown to do. However, the means of Patent Document 1 is merely a means for performing the above-mentioned conventional sea urchin shell splitting method into two, and the inconvenience that one or two hitting the cracks are damaged cannot be completely eliminated. And the shell divided into two has no utility value.

  In Japanese Patent Laid-Open No. 7-194347 (Patent Document 2), the mouth side is placed on the belt conveyor by a banded saw blade or the like at the cutting position while placing and transferring the sea urchin with the mouth side relatively flat on the upper side. A treatment method is shown in which a part is cut parallel to the belt conveyor to expose the gonad without damaging the gonad.

  However, the side of the sea urchin's mouth is a relatively flat surface, and the sea urchin's gonad extends to the flat back of the mouth side, so it is parallel to the belt conveyor surface. If you try to cut the side of the sea urchin's mouth, the entire flat surface will be excised, which inevitably cuts part of the gonad. In the method of cutting sea urchin shells in a plane parallel to the belt conveyor as in Patent Document 2, there is an inconvenience that it is difficult to cut at the boundary between sea urchin gonads and mouth organs.

  In the sea urchin processing apparatus of the present invention, it is desirable that the circular blade has a stopper in the vicinity of the blade edge for preventing the blade edge from entering at a constant depth in the sea urchin shell. After the cutting tool has opened a hole in the sea urchin shell, the entire circular blade may be pushed into the sea urchin shell and damage the gonad, but the cutting tool has the stopper so that the circular blade Since the blade edge of the wing stops, damage to the gonad can be prevented.

  In the sea urchin processing apparatus of the present invention, the anti-blur needle A for preventing the relative position between the sea urchin fixed to the fixture and the rotating circular blade may be fixed to the tip of the rotating shaft. When the anti-blur needle is fitted into the sea urchin mouth, the rotation of the circular blade relative to the sea urchin is stabilized.

  In the sea urchin processing apparatus of the present invention, it is desirable that the insertion width of the anti-blur needle into the sea urchin is substantially equal to the diameter of the sea urchin mouth, and the tip of the anti-blur needle protrudes beyond the edge of the circular blade. . Since the anti-blur needle is securely fitted and fixed to the sea urchin opening by the anti-blur needle of this structure, the horizontal blur of the entire cutting tool is suppressed, so that the blur of the rotating circular blade is suppressed and the sea urchin shell Cutting is stabilized.

  In the sea urchin processing apparatus of the present invention, a fixing tool for fixing a sea urchin when cutting a sea urchin shell is fixed on a fixing base, and the fixing tool has a plurality of protrusions protruding vertically. Can be used. By using such a sword mountain, the sword mountain protrusion and the sea urchin spine are entangled by pushing the sword mountain protrusion until it contacts the shell by sewing the gap between the sea urchin spines, and the sea urchin is fixed on the fixture. .

  The sea urchin treatment method of the present invention is fixed on a fixture with the sea urchin side facing up, and a circular blade rotating from a substantially vertical direction is brought into contact with the sea urchin side of the sea urchin to The mouth boundary is cut into a circle to form a hole, the internal organs are removed from the formed hole, and the gonad is stripped off.

  Further preferred sea urchin treatment method of the present invention is to fix the sea urchin on the fixture with the mouth side facing up, fit the anti-blur needle into the sea urchin's mouth, and from substantially perpendicular to the sea urchin mouth side. A rotating circular blade is brought into contact with each other, and the boundary between the sea urchin gonad and mouth is cut into a circle to form a hole, the internal organs are removed from the formed hole, and the gonad is stripped off.

  To fix the sea urchin to the fixed base, the sword mountain protrusion and the sea urchin spine are pushed by pushing the protrusion of the sword mountain as a fixture fixed to the fixed base until it touches the shell through the gap between the sea urchin spines. It is a method of entangled and fixing a sea urchin on a fixture.

  In the sea urchin processing apparatus and sea urchin processing method of the present invention, the cutting edge of the circular blade rotating with respect to the side of the sea urchin's mouth is brought into contact with the blade from the vertical direction to cut the boundary between the sea urchin's gonad and mouth. It can be surely cut by a simple operation, and the gonad can be peeled off and collected after removing the internal organs without cutting the gonad. In the sea urchin treatment method of the present invention, the protrusions around the mouth organ are also removed together, so that the gonad can be easily peeled off. Furthermore, the sea urchin shell opened in a circular shape can be used as a tableware for putting sea urchin dishes and the like before serving, or as a food container or a frozen food container containing foods such as delicacies.
