Description

The present invention is, for example, relates to how to cut the meat a good Cannonball jellyfish and rhopilema esculentum in diameter for the premium ingredients.

  As for edible jellyfish, so-called “salt jellyfish” in which the circular umbrella portion of jellyfish is processed with salt and alum is traded as a product in this kind of industry. And the price varies greatly depending on its size. For example, a diameter of 33 cm or more is a first grade product, less than 33 cm to 28 cm is a second grade product, less than 28 cm to 23 cm is a third grade product, less than 23 cm to 18 cm is a fourth grade product, and the diameter is less than 18 cm It is ranked as a non-genuine product and used as a guide for transactions. The reason for this is that when a circular umbrella is cut with a kitchen knife (called guillotine cut), when it is placed on a plate after cooking, a long piece can be placed softly (with a sense of quality). On the other hand, a short-cut object is less prominent, so it cannot be placed nicely, so it has been evaluated that a jellyfish with a large diameter that can be cut long is higher.

  Recently, however, high-quality bizen jellyfish are rare because some of them are too large or too early, and there are rarely large ones. However, most of them have a diameter of 20 cm or less. Most of them are 15cm or less in diameter, and all of them are traded as non-standard products, and it is said that the producers are not profitable even if they take time to process them in order to provide high-quality jellyfish. There is an inconvenience.

  In addition, as a method for cutting a small jellyfish, a technique (invention) related to the same applicant is already known. The known technique (invention) is to cut a jellyfish having a substantially circular shape into a non-linear shape so as to be formed into a narrow strip having a length equal to or greater than the diameter of the circular shape. This is a processing method (Patent Document 1).

  The problem to be solved in this cutting method is that the conventional guillotine cut for a small jellyfish has a length longer than the diameter that cannot be achieved, that is, cut in a non-linear shape, so that it is cut into a strip longer than the diameter. By making the fillet, it became possible to use the fillet and solved the problem of the small jellyfish that the chef avoided.

  And even if the diameter of the uncut jellyfish is a small diameter that cannot be treated as a luxury product by the above-mentioned cutting method, it is treated as a luxury product that can be softly and smoothly arranged, which could not be achieved with conventional guillotine cuts. It can be cut into scale fillets.

Japanese Patent No. 3229306

  However, the cutting method described in Patent Document 1 is characterized by a cutting jig (blade) and its use. In short, the producer cuts the jellyfish in a spiral shape while avoiding guillotine cutting. Therefore, the jig for cutting jellyfish is provided with blades arranged in a spiral shape at regular intervals, and the width of the interval between the blades. It was only cut.

  By the way, depending on the restaurant or chef, even if there is a desire to use a slightly narrower jellyfish cut width or a slightly wider one depending on the cooking method, it is already a certain width at the time of purchase. Therefore, there is a problem that the hope cannot be fulfilled. Also, on the producer side, in order to mechanically efficiently mass-produce, the blade width of the cutting jig cannot be narrowed or widened, and the apparatus for mounting the cutting jig itself cannot be changed. Since it is used, and it is necessary to sharpen the blade after use for a certain period of time, it is a fact that a uniform jig is used, and it can respond to the request of the restaurant or chef It also has the problem of not.

  Therefore, in the jellyfish cutting method and cut jellyfish according to the known technology, in accordance with the demands of producers and consumers (buyers) such as restaurants or cooks, and in addition, jellyfish small jellyfish, A simple guillotine cut has a problem to be solved so that it can be cut at least to a grade 1 or grade 2 product in accordance with any desired width.

The method of cutting a jellyfish according to the present invention is a method of cutting a small jellyfish that is not rated, and is formed by folding a circular jellyfish into four along a fold line passing through the center, One of the disconnected side from the outer peripheral edge to the center, and on the eighth fold folded at fold lines passing through the further around the quarto jellyfish disconnected said, the jellyfish was the octavo transversely with respect to the diameter direction rather than the radial direction The guillotine is cut into a plurality of strips with an arbitrary width.

  In the invention of the above cutting method, the arbitrary width is about 2 to 8 mm; and the guillotine cut is a roll-shaped cutting in which a plurality of disk-shaped blade portions are attached to a shaft at an arbitrary required interval. Mechanical cutting with a blade is included as an additional requirement.

  According to the jellyfish cutting method according to the present invention, even a small jellyfish that is not rated can be made into a first-grade product or a second-grade product by folding it into eight pieces and performing a simple guillotine cut. From this situation, it is possible to provide a cut jellyfish that can meet the demands of producers and consumers.

  In addition, the cut jellyfish according to the present invention can be cut to an arbitrary width within a range of about 2 to 8 mm by guillotine cutting, thereby producing an excellent effect that the width of cooking by the cook is widened.

It is the small jellyfish used with the cutting method of this invention, Comprising: It is the top view which showed the folding condition roughly. It is the perspective view which showed the condition which folds the same small jellyfish into four and shows the condition which cuts off one side of two sheets, and shows the condition folded into eight. It is explanatory drawing which showed the condition which chops up the small jellyfish folded in the same way with a guillotine cut. It is the perspective view which showed the principal part of the guillotine cutting apparatus which showed the condition which mechanically cuts the small jellyfish folded into eight by the guillotine cut. It is a perspective view which shows the cutting blade of the other Example in the condition which guillotine cuts the small jellyfish folded into the same eight. It is a top view which shows the principal part of the grindstone jig | tool used for sharpening of the cutting blade used for a guillotine cutting apparatus.

  Next, the present invention will be described in detail based on the specific embodiments shown in the drawings. FIG. 1 is a plan view of a small jellyfish, FIG. 2 is an explanatory view in a process before guillotine cutting of the small jellyfish, FIG. 3 is an explanatory view showing a folded state immediately before cutting, and FIG. FIG. 5 is a perspective view showing a cutting device, and FIG. 5 is an enlarged perspective view showing a cutting blade used in the cutting device.

  First, the foot part is cut off from the umbrella part of the small jellyfish, and only the umbrella part is soaked with salt and alum for the required number of days, then the alum is removed with saturated saline and salted, and the moisture is removed moderately It is considered as a trade target product. This is substantially the same as the conventional jellyfish processing. Hereinafter, a jellyfish that is a non-genuine product having a diameter of less than 18 cm in the circular umbrella portion, as shown in FIG. Called.

  The small jellyfish 1 is an external product such as a circular shape having a diameter of about 12 cm, for example. First, as shown in FIG. 1, the small jellyfish 1 is entirely divided along folding lines a and b passing through the center 0. Fold it. As shown in FIG. 2, one side 2 of the two-layered portion of the small jellyfish 1 folded into four is separated from the outer peripheral end to the center 0 by an appropriate means, for example, a hook 3 or the like, Furthermore, when the whole is folded along the fold line c, the whole is folded into eight as shown in FIG.

  As shown in FIG. 3, the small jellyfish 1 entirely folded in eight is, for example, as a first embodiment, a required width (about 2 to 8 mm) along a virtual line A (cut line) by a knife. Cut guillotine across multiple strips at any width). The length of the guillotine cut, for example, through the center of the width of 8 mm is approximately 33.6 cm, 29.6 cm, 24.8 cm, 19.2 cm, 14.4 cm, 9.6 cm, and the diameter is 12 cm or more. All non-genuine items of less than 18cm become a first-class product by guillotine cut.

  Using this principle, for example, even an external jellyfish with a diameter of about 10 cm is cut by guillotine cutting into a plurality of strips of about 2 to 8 mm width by folding in eight, for example, the center of 8 mm width The lengths through are approximately 28 cm, 23.2 cm, 17.6 cm, 12.8 cm, and 8 cm, and the outer products having a diameter of 10 cm to 11 cm are all guillotine cut and become all second-class products. In short, it can be cut to any width. In fact, in some countries, jellyfish with an umbrella of less than 10 cm are prohibited from harvesting (forbidden fishing) to protect resources.

In the first embodiment, an example in which guillotine cutting is performed by simple means using a knife has been described. However, this simple means is inefficient and is not suitable for mass production.
Therefore, as shown in FIG. 4, the second embodiment is mechanically performed by the guillotine cutting device 4. This guillotine cutting device 4 includes a bowl-shaped supply unit 5 provided with an appropriate inclination, and a belt conveyor 6 that is arranged up and down across the bottom plate 5a of the supply unit 5 to place a jellyfish and convey it to the tip side. A cutting blade 7 provided on the front end side of the belt conveyor 6, a drive unit 8 such as a motor for driving the cutting blade 7, a discharge rod 9 for flowing down the cut jellyfish, and storing the discharged jellyfish It is comprised from the storage part 10 to do.

  The cutting blade 7 is, for example, a roll shape in which a plurality of disk-shaped blade portions 7 a are attached to the shaft 11 at an arbitrary interval within a range of 2 to 8 mm, for example, and the shaft 11 is on both sides of the supply unit 5. A pulley 12 is attached to one end of the shaft 11 so as to be rotatable via a bearing on the wall, and the pulley 12 is connected so as to be rotationally driven via a drive unit 8 such as a motor and a drive belt 13. Has been. The cutting blade 7 is surrounded by an appropriate cover member 14 on the upper surface side for safety.

  With respect to the guillotine cutting device 4 configured in this manner, the small jellyfish 1 folded in eight as shown in FIG. 3 is placed on the belt conveyor 6 of the supply unit 5 as shown in FIG. Instead, it is placed and supplied sequentially so as to cut in the horizontal direction (cut line A direction indicated by the phantom line), and cut into a 4 to 8 mm wide strip by the cutting blade 7. In this case, since the supply unit 5 is inclined, the supplied small jellyfish 1 is stably supplied from the belt conveyor 6 to the cutting blade 7 side, and is formed into a narrow strip shape having a predetermined arbitrary width. Guillotine cut.

  As for the cutting blade 7, an example of cutting with a single roll-shaped one having a plurality of blade portions 7a has been shown, but the present invention is not limited to this example. For example, FIG. As shown, the foldable small jellyfish 1 shown in FIG. 3 can be guillotine cut using two roll-shaped cutting blades 15 and 16. In this case, the cutting blades 15 and 16 are each attached to the shaft 11 at an arbitrary interval of about 4 to 16 mm, for example, with the interval between the disk-shaped blade portions 15a and 16a. Are arranged adjacent to each other, and the blade portions 15a and 16a are inserted into each other at an arbitrary interval of about 2 to 8 mm, and more than 20 mm are inserted into each other.

  The two cutting blades 15 and 16 are arranged so that the blade portions 15a and 16a are rotated inwardly by appropriate driving means, and in the rotationally driven state, the eight-folded small jellyfish 1 is placed between adjacent ones. By dropping, as shown by the cut line A in FIG. 3, both the blade portions 15a and 16a are efficiently guillotine cut to an arbitrary width within a range of 2 to 8 mm. In addition, when cutting with the roll-shaped cutting blade according to the second embodiment and other examples, in the case of mass production, it is electrically driven, but if there is no need for mass production, the whole is downsized, It can be driven manually at each restaurant and cut.

  As for the roll-shaped cutting blades 7, 15, 16 used as the second embodiment and other examples, a plurality of disk-shaped blade portions 7 a, 15 a, 16 a are attached to the shaft 11. When sharpening these blade portions, for example, as shown in FIG. 6, sharpening is performed using a special grindstone jig 17. The special grindstone jig 17 is provided with a cut portion 19 at one end of the grindstone 18 at intervals corresponding to the blade portions 7a, 15a, 16a of the cutting blades 7, 15, 16; The blade portions 7a, 15a and 16a are formed in a shape along the cutting edge shape. That is, one wall portion 19a of the cut portion 19 is formed vertically and the other wall portion 19b is inclined, and the blade edge is sharpened by the inclined wall portion 19b.

  The grindstone jig 17 is provided with a bearing portion and a drive portion so that the cutting blades 7, 15, 16 to be set can be rotationally driven. Further, the grindstone 18 is interposed via a rail-shaped guide member 20. It is configured to be able to slide and move horizontally. Then, as a preparatory step, whether the cutting edge 19 of the grindstone 18 is applied to the cutting blades 7, 15, 16 set on the grindstone jig 17 (lightly contacted), and the position is accurately aligned. After confirming whether or not, the set cutting blades 7, 15, 16 are rotated, and the grindstone 18 is moved to sharpen the blade portions 7a, 15a, 16a. This sharpening is substantially completed within a few seconds, and even if a cutting blade is set and a preparation stage is included, sharpening can be performed in a few minutes.

  Thus, even the cutting blades 7, 15 and 16 for cutting guillotine can be sharpened in a few minutes. Using such cutting blades, small-sized jellyfish, etc. can be classified into first and second grades. It can be efficiently produced by mechanical guillotine cutting.

  In any case, the method of cutting the small jellyfish 1 that is an external product according to the present invention is that the entire small jellyfish 1 is folded in four along the fold lines a and b passing through the center 0. After separating one side 2 of the overlapped portion from the outer peripheral edge portion to the center 0 by an appropriate means, the whole is folded along the fold line c so as to be folded in eight, and is folded in eight. By guillotine cutting the small jellyfish 1 to the required width (any width of 2 to 8 mm) in the lateral direction, all the external products with diameters of 12 cm to less than 18 cm become first class products, and the diameter is Since all the 10 to 11 cm non-standard products are second-class products, it is particularly advantageous for producers who suffer from resource depletion, and can be handled as a luxury product for cooks. Is an edible material (medium Cuisine, it is possible to be widely used as a Japanese cuisine).
