Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a device for removing meat from the thigh of a crab's walking leg.

(B) Conventional Technology Traditionally, crabs such as crabs, crabs, snow crabs, and red king crabs have been cooked or canned for consumption at home or as a specialty crab dish.

The bulk of crab meat is made up of leg thigh meat, and the amount of thigh meat taken out greatly affects yield.

To remove the thigh meat, cut both ends of the thigh of the walking leg with a cutting device such as a chain saw in advance to leave both ends of the thigh wide open, and then remove the thigh meat. It can be taken out by mechanical work or by hand.

That is, in the case of mechanical work, the thigh of the walking leg whose both ends have been cut off is inserted between clamping pressure rollers and compressed, and the thigh meat inside the shell is squeezed out.

In addition, in the case of manual work, the back side of the shell of the walking leg thigh, which has been cut off at both ends, is further cut vertically with a prescribed cutting tool to allow the shell to expand outward. The thigh meat is made easy to remove, and then it is pushed out from one side with a stick-like removal tool or scraped out with an elongated spoon-like removal tool.

In addition, in view of the low demand for crabs in general households due to the troublesome work of removing thigh meat, recent efforts have been made to remove thigh meat that has already been taken out manually or by machine, as described above. The meat is sold as a product.

(c) Problems to be solved by the invention However, in the case of mechanical work, when removing thigh meat, the quality of the meat is often damaged because it is squeezed out with rollers, and the efficiency of removing thigh meat while maintaining its commercial value is poor. This has led to a decline in sales prices, leading to an increase in sales prices.

Moreover, in such mechanical work, there is a problem in that the thigh meat is not sufficiently removed and there is a lot of loss.

Furthermore, although manual work results in less loss than mechanical work, it requires a large amount of manpower and time, and this also results in an increase in the selling price due to labor costs and the like.

Moreover, when it is done manually, there is a big problem that the meat quality is often damaged and the yield is low.

In addition, when eating thigh meat at home, the cost of removing the thigh meat from the shell is high, so they buy the thigh meat with the shell on.
In this case, not only is it troublesome to take out the thigh meat, but the thigh meat is taken out in a state where it has been finely shredded and damaged, making it impossible to fully enjoy the originally delicious walking leg thigh meat. This is a problem.

(d) Means for Solving the Problems In the present invention, the base end of the blade for longitudinally cutting the shell of the leg thigh of a crab is connected to the tip of the extractor main body, and the same It is an object of the present invention to provide a tool for extracting meat from a crab's walking leg thigh, which has a continuous pressure hole at the tip of the blade part for pressing the thigh meat within the shell of the walking leg thigh. .

(E) Effect When removing thigh meat from the thigh of a crab's walking leg using the extractor according to the present invention, both ends of the thigh of the crab's walking leg are cut open in advance, and a pressing body is inserted. Then, with the thigh of the walking leg so that the longitudinal direction is the front-back direction, the pressing body is brought into contact with the front end surface of the thigh meat from the front end opening of the thigh of the walking leg, and the blade part is If you bring the blade into contact with the front end of the shell of the thigh of the walking leg and pull the main body of the retrieval tool in the same state, you can move the blade in the longitudinal direction to the opening at the rear end of the thigh of the walking leg. The part cuts the shell of the thigh of the walking leg longitudinally, and the pressing body presses the thigh meat to release the same thigh meat from the rear end opening of the thigh of the walking leg. It is.

At this time, the thigh meat is taken out in a state where the shell of the thigh of the walking leg is cut vertically by the blade, so it is perfectly shaped without being damaged or deformed. .

Note that, contrary to the above, the direction of movement of the pressing body and the blade portion may be from the rear end opening toward the front end opening.

(f) Effects According to the present invention, the work of removing thigh meat can be performed safely, quickly, and easily, and the removed thigh meat is not damaged or loses its shape, and is completely preserved. Because it is in a shaped state, it is possible to secure product value, and the number of ways to cook it has increased significantly.Moreover, the yield is good, and the selling price can be reduced, increasing demand from ordinary households. It has the effect of

Moreover, since the structure of the extractor is simple,
The manufacturing cost of the extraction tool is low, and if it is provided as a service for selling leg thighs, it will greatly contribute to increasing sales of walking leg thighs.

Furthermore, if the extraction tool is attached to an arm that operates in the same way as manual operation, and the extraction work is performed mechanically, it is possible to significantly reduce labor costs and further reduce the selling price. It has the effect of being able to

(G) Embodiments The embodiments of the present invention will be explained in detail based on the drawings.
FIG. 1 is a side view showing a crab walking leg thigh meat removal tool A according to the present invention, and FIG. 2 is a side view showing the same removal tool A.
FIG.

The extractor A has a sickle-shaped blade part 2 connected to the tip of a rod-shaped main body 1, a pressing body 3 connected to the tip of the blade part 2, and a gripping rod 4 at the base end of the main body 1. They are orthogonally connected in a T-shape in plan view.

Then, as shown in FIGS. 3 to 5, the blade portion 2
The blade is shaped like a sickle, that is, approximately U-shaped, and the cutting edge 2a is formed on the inner curved surface.
is made of a material strong enough to cut the shell B' of the thigh B of the crab's walking leg.

The shape of the blade part 2 is not limited to a curved shape, but various shapes such as a fishing shape and a hook shape can be considered. Any shape may be used as long as it can be cut.

Further, the pressing body 3 is formed into a plate-like ring shape that is substantially similar to the cross-sectional shape of the thigh part B of the walking leg.
The inner surface 3a of is in full contact with the end surface of the thigh meat b,
In addition, it is configured to move while pressing the thigh meat b within the shell B'.

The angle θ between the virtual extension plane formed by the inner surface 3a of the pressing body 3 and the main body 1 is configured to be an obtuse angle of 90° or more.

Note that the shape of the pressing body 3 may be any shape as long as it can push out the thigh meat b as a whole without damaging it.

Furthermore, although the entire extraction tool A is integrally molded from the same material, each part may be constructed from different materials.

The extractor A according to the present invention is configured as described above, and when the thigh meat b is extracted from the thigh B of a walking leg using the extractor A, the following procedure is followed. It's good.

That is, both ends of the thigh B of the walking leg are cut open in advance, and then the worker grasps the thigh B of the walking leg with one hand so that the longitudinal direction is located at the front and back, and then cuts the thigh B with the other hand. While grasping the gripping rod 4 of the extractor A with your hand, hook the blade part 2 onto the upper center of the front end opening B-1 of the thigh B of the walking leg, and press the inner surface 3a of the pressing body 3. All you have to do is bring the entire surface into contact with the front end surface of the thigh meat b, and in the same state, pull the gripping rod 4 toward you while gripping it.

At this time, the cutting edge 2a of the blade part 2 vertically splits the upper surface of the shell B' in the longitudinal direction as the operator pulls it toward the operator. By doing so, the internal thigh meat b is smoothly pressed by the pressing body 3 inside the same shell B' and is released all at once from the rear end opening B-2 without losing its shape. It is something.

6 to 15 show extractors C, D, E, F, G, H, I, and J as other embodiments, respectively, and are constructed as follows.

That is, the extraction tool C is the front half 5a of the main body 5.
and the pressing body 6 are disposed at orthogonal positions, and the angle θ indicated by the extractor A is 90°,
The rear half 5b of the main body 5 is bent toward the side opposite to the pressing body 6.

Therefore, when using the extractor C, the blade 7 is hooked on the front end opening B-1 of the thigh B of the walking leg, and the front half 5a of the main body is parallel to the upper surface of the thigh B. If you pull the gripping rod 8 toward you in the same state, the pressing body 6 will naturally press straight against the thigh meat b in a state perpendicular to the virtual central axis of the thigh meat b. Therefore, the thigh meat b can be taken out smoothly and reliably.

Further, in FIG. 7, a scraping spoon 10 is connected to the left end of the gripping rod 9 of the extraction tool D, and a scraping fork 11 is connected to the right end.

The scraping spoon 10 is particularly convenient when used to scrape out crab shoulder meat.

Further, the scraping fork 11 is convenient for scraping out fillets and the like at the tip of a walking leg.

The extraction tool E shown in FIG.
2, a gripping rod 14 is attached via an adjustment tool 15 so that the sliding position can be adjusted in an orthogonal state.

16 is a blade portion, and 16' is a pressing body. Therefore,
When removing the thigh meat b using the tip end side blade 16 or pressing body 16', use the gripping rod 14.
By fixing the position on the scraping spoon 13 side, the gripping rod 14 can be easily gripped during such work. Also, when using the scraping spoon 13, the gripping rod 14 If the spoon 13 is fixed in position on the blade portion 15 side, the spoon 13 can be used easily.

In addition, the extractor F shown in FIGS. 9 and 10 is
The main body 17 is longitudinally elongated from front to back, and is formed into a narrow plate shape, and the upper and lower surfaces of the main body 17 are formed into convex and convex curved surfaces so as to be easily grasped.

Then, a blade part 18 is connected to the front end of the main body 17, and a pressing body 19 is connected to the front end of the main body 17.
A scraping spoon 20 for scraping out shoulder meat is connected to the rear end.

In addition, the extractor G shown in FIGS. 11 and 12
The main body 21 is formed in the shape of a narrow plate in the front and rear longitudinal directions, and in a substantially S-shape, and the front end of the main body 21 is provided with a blade part 22 in the form of a substantially right triangular plate, and a pressing body is attached to the front end of the main body 21. 23 are connected in series, and a scraping spoon 38 is connected to the base end of the main body 21.

The blade portion 22 is formed into a right triangular plate shape having an inclined portion that is high at the front and low at the rear, and has a cutting edge 22a formed on the oblique side thereof, and the cutting edge 22a is directed toward the main body 21.

Therefore, in the case of such a retrieval tool G, since the blade portion 22 that supports the pressing body 23 in a continuous manner at the front end is tapered forward, the front end opening B-1 of the thigh B of the walking leg Insert the pressing body 23 further and press the main body 21.
When pulled toward this side, the blade part 22 vertically expands the shell B' of the thigh B of the same walking leg while smoothly cutting the upper surface of the shell B' longitudinally with the cutting edge 22a, and at the same time The thigh meat b is pulled out by the pressing body 23 without being damaged in any way.

Moreover, the extractor H shown in FIG.
A right triangular plate-shaped blade part 25 having an inclined part with a low front and high back height is continuously provided at the front end, a pressing body 26 is continuously provided at the front end, and a scraping spoon 27 is continuously provided at the rear end. It is something.

Then, a cutting edge 25a is formed on the inclined part of the blade part 25 so that the cutting edge 25a is located in front of the main body 24, and furthermore, a pressing body 26 is connected and supported on the front end of the blade part 25. There is.

Further, the take-out tool I shown in FIG. 14 has a main body 28 formed in the same manner as the main body 24 of the above-mentioned take-out tool H, and a presser guide body 29 extended in front of the cutting edge 30a in close opposition to each other. .

Since the presser guide body 29 presses the upper surface of the shell B' immediately before being cut by the cutting edge 30a of the blade part 30, the cutting by the cutting edge 30a is smoother than in the case of the take-out part H, and This will definitely be done.

Moreover, since the presser guide plate 29 is closely opposed to the cutting edge 30a, it is possible to prevent the worker's hands and fingers from directly touching the cutting edge 30a.

31 is a scraping spoon.

Therefore, this extraction tool I and the above-mentioned extraction tool H are different from those that pull out the thigh meat b by applying tension toward the front, like the aforementioned extraction tools A, C, D, E, F, and G. Differently, the thigh meat b is pushed out by pressing forward, and the pushing body 26 is inserted from the rear end opening B-2 of the walking leg thigh B, and the pushing body 26 pushes out the thigh meat b. When pressed so as to push out the thigh meat b, the blade part 25 expands the shell B' of the thigh part B of the same walking leg vertically and smoothly cuts the upper surface of the shell B' in the longitudinal direction with the cutting edge 25a. It can be cut vertically, and the thigh meat b can also be removed without losing its shape.

Furthermore, if the intake container or the like is placed in the direction in which the thigh meat b is pushed out, the thigh meat b can be taken out and accommodated smoothly at the same time.

In addition, the extraction tool J shown in FIG. 15 has the extraction tool G designed like a dropper of a tree, and
A plug protrusion 33 is provided on the upper front side of the main body 32.

In the figure, 34 is a blade part, 34a is a cutting edge, 35 is a pressing body, 36 is a scraping spoon, and 37 is a locking hole, through which the extraction tool J is locked to a predetermined hook. We are making it possible to do so.

In addition, when the thigh meat b is to be removed by mechanical work, the main body of each extracting tool is connected to the tip of an arm configured to move back and forth in a reciprocating manner. If it operates in the same way, it will be possible to take out a large amount of thigh meat b of the walking leg thigh B, which is sequentially transported by the transport device, in a short time.
This will lead to a reduction in personnel costs and, by extension, a significant reduction in selling prices.
