The apparatus for treating the shellfish is equipped with a mechanism for removing the accessory parts, a transporting unit, an opening mechanism and a first and a second separating mechanisms (nozzles) so as to realize the methods for treatment and the nozzles are installed on the outside of the adductor muscle (the unstriated muscle part) of the shellfish.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for treating shells, including shells of scallops and abalone shells, including shells (including shells) and accompanying parts such as strings and orchids, and shells used therefor. The present invention relates to a processing apparatus, for example, suitable for automatically removing a scallop or ancillary parts from a scallop shell by a machine prior to shipping the scallop scallop to a market.

[0002]

2. Description of the Related Art Shellfish such as scallops and abalones are shipped to the market in various commercial forms. For scallop, for example,
There are the following product forms. 1. Raw product with shell. 2. A raw product in which one shell is opened and removed, leaving the midgut gland (commonly known as uro), scallop, orchid, and string in the other shell. 3. Raw products with only accompanying parts such as uro, gonad (common name, orchid), mantle (common name, string), heart, gills, tentacles. 4. Products with only raw scallops (also called closed-shell muscles and crested muscles). 5. Raw orchid-only products (however, orchids are only available when spawning). 6. Only raw string and gill products.

[0003] For products other than products that are shipped to the market with their shells, orchids, strings, scallops, etc. must be removed from the shells. If the taking-out work is manually performed, much labor and time are required. Therefore, in order to carry out the work efficiently in a short time, a method of automatically opening a shell and taking out a scallop has been developed. As one of them, there is a method of taking out a scallop shown in FIGS. 11 (a) to 11 (d). It is the following method.

(1) An operator horizontally sets scallops 90 one by one on a work table attached to a belt conveyor. In this case, two shells 91 of the scallop 90,
Of the 92, the shell (usually called a right shell) 91 (usually called a right shell) is set downward with a shell generally called an upper shell (shallow and brown, usually called a right shell). (2) Scallop 9 conveyed by belt conveyor 9
The tip 93 of the two shells 91 and 92 of FIG.
11 (b), the tip is removed as shown in FIG. 11 (b), and openings 94 are formed in the shells 91, 92 as shown in FIG. 11 (c). Cooling water is applied to the diamond cutter at the time of cutting to prevent the shells 91 and 92 from becoming hot, to make the cutter last longer, and to prevent scattering of cuttings. By the way shells 91, 9
When 2 becomes hot, the heat is transmitted to the internal shell 95, and the freshness and quality of the shell 95 deteriorate. (3) As shown in FIG. 11D, a separating tool 96 such as a spatula is pushed into the inside of the scallop 90 from the opening 94 along the inner surface of one of the shells 91 to separate the shell 91 from the scallop 95. The scallop 90 from which the shell 91 has been separated is sent out from the work table. (4) Uro, heart, string, gill, orchid, etc., attached to the other shell (shell which is deep, curved, and usually called a left shell) 92 of the sent scallop 90 Parts other than 95 (hereinafter collectively referred to as ancillary parts) are manually removed. (5) The separating tool 96 is pushed along the inner surface of the shell 92 to separate the other side of the shell 95 from the shell 92 and take out the shell 95.

[0005]

The above-mentioned method for removing the scallop can be labor-saving and more efficient than performing all the steps manually, but since the scallop is separated from the hull by pushing the separating tool, the scallop may be damaged. In some cases, the scallop may be chipped or torn, which may lead to a decrease in the quality and grade of the scallop, and it is difficult to remove the scallop without waste.

[0021]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (Embodiment 1 of Shellfish Processing Method) One embodiment of a shellfish processing method of the present invention will be described in detail with reference to FIG. This embodiment relates to a case in which a shell 1 is a scallop having two shells 2 and relates to a method for removing a scallop and an accompanying part.

In this embodiment, as shown in FIG. 1A, the shell 1 is placed on the tray 20 of the carrier 11 and transported.
The work of placing the shell 1 on the tray 20 can be performed manually or automatically by a machine. In this case, shellfish 1
And the top and bottom of the shell 1 are aligned. For example, the connecting side 21 (FIG. 1 a) of the shell 1 to which the two shells 2 are connected is aligned in the same width direction of the carrier 11. Usually, a flat shell (brown shell: right shell) with a shallow curvature called the upper shell may be set down, and conversely, a shell with a deep curvature (white shell: left shell) ) May be set down.

The shell 1 placed on the tray 20 is transported by the transport body 11 and, when transported to a predetermined position, utilizes a belt conveyor disposed above the transport body 11 as shown in FIG. It enters under the holder 22 and is sandwiched between the holder 22 and the tray 20 of the carrier 11. The carrier 11 and the holder 22 intermittently run at the same speed, and stop and start in synchronization. When the shell 1 is transported over the blade 23, the transport body 11
And the holder 22 is stopped, and the connecting side 2 of the lower shell 2 is stopped during the stop.
As shown in FIG. 3 (b), the two blades 2
3, the opening 5 is formed. Thereafter, the carrier 11 and the holder 22 start running in synchronization with each other,
The shell 1 on the tray 20 is transported. Shell 1 is the first nozzle 2
5 (FIGS. 1c and 4), and
And the holder 22 stops.

During the stop, the shell 1 is sucked and held on the tray 20 by a suction device built in the tray 20. In this state, as shown in FIG. 4, a liquid 26 ejected from a nozzle (ejection body) 25 of the first separation mechanism 13 at a high pressure is ejected from the opening 5 of the shell 2 along the inner surface of the shell 2 above. The shell 2 is removed from the upper surface of the shell 3 by opening the shell 2 by contacting the body (shell) 3 and the shell 2. In this case, as shown in FIG. 8 and FIG. 9, the body (the scallop: also referred to as closed-shell muscle and the striated muscle) extends along the inner surface of the shell 2 from the outside of the closed-shell muscle (unstriated muscle portion) 60 of the shell 1.
When sprayed toward the portion where the shell 3 and the shell 2 adhere, the shell 2 is easily detached from the upper surface of the scallop 3 (the shell is easily opened).
This is the same regardless of whether the shell 3 is removed from the brown shell (right shell) or the white shell. The structure and size of the nozzle 25, the ejection pressure (liquid pressure) of the liquid 26 ejected from the nozzle 25, the ejection amount (liquid amount) of the liquid 26 ejected from the nozzle 25, and the like can be arbitrarily selected. For example, as shown in FIG. 10, a nozzle 25 having a horizontally long ejection port 61 is suitable as the nozzle 25. The liquid pressure is 200 kg / cm 2 and the liquid volume is 11.2 l / min.
Degree. The injection of the liquid 26 is performed at the opening 5
Not only from the beginning, but also from other places. For example, the nozzle 25 is inserted through a gap between the upper and lower shells slightly inside the hinges (ligaments) of the shell 2 to eject a liquid from the outside of the closed shell muscle (unstriated muscle portion) 60 of the shell 1 or other liquids. It is also possible to insert the nozzle 25 from a location and eject it. The ejection angle of the liquid from the nozzle 25 can be arbitrarily selected.

Although one nozzle 25 is shown in the drawing, a plurality of nozzles 25 are arranged on the outer periphery of the shell 1, and the liquid 26 jetted from the nozzles 25 is passed along the inner surface of the shell 2 to the body 3 and the shell 2. The liquid ejected from the nozzle 25 may be separated from the shell 2 by colliding the shell 3 with the shell 2 by rotating the nozzle 25 or rotating the shell 3 in the outer circumferential direction. The scallop 3 and the shell 2 can be separated from each other by, for example, applying 26 to the attachment portion between the scallop 3 and the shell 2 along the inner surface of the shell 2 from multiple directions. The liquid 26 can be water or another liquid. In this case, if the liquid 26 is formed into a high-pressure thin jet, the shell 3 and the shell 2 are easily separated. When the upper shell 2 is opened, the transport body 11 resumes running and transports the shell 1. When the shell 1 is transported to the vicinity of the accompanying part removing mechanism (suction device) 10, the transport body 11 stops again.

During the stop, the lower shell 2 is pressed against the tray 20 by the first holder 27 as shown in FIGS. In this state, the suction port 28 of the accessory removing mechanism (suction device) 10 is brought close to the lower shell 2 to which the scallop 3 is attached, and the accessory 4 such as uro, string, orchid is sucked and removed. The sucked attached part 4 is put into the tank 30 through the discharge path 29, and water, fine dust, etc. contained in the put attached part 4 pass through the filter 31 in the tank 30, It is discharged out of 30. The auxiliary part 4 accumulated in the tank 30 can be used for uro, string,
Uro is discarded according to the type of orchid, etc., and edible ones such as string and orchid are post-processed and provided for edible use. When the attached part 4 is removed from the shell 2, the form of the product is removed, for example, only the urine is removed and discarded, the remaining attached part 4 is removed and commercialized, and the string and gill are removed together. Can be removed individually, or two or more can be collectively removed, or all of them can be removed collectively.

As described above, the carrier 11 from which the suction and removal of the associated part 4 is completed resumes running, and the shell 1 from which the associated part 4 has been removed is replaced with the second separating mechanism shown in FIGS. When the transport body 11 is transported to the vicinity of the 14 nozzles 32, the transport body 11 stops again. During this stop, the lower shell 2 is pressed against the tray 20 by the second holder 33 and is held by the tray 20. In this state, as shown in FIG. 6, a liquid 34 jetted from the nozzle 32 at a high pressure is jetted along the inner surface of the lower shell 2 to form the shell 3 and the shell 2.
To separate the scallop 3 from the shell 2. At this time, as shown in FIG. 6, when the scallop suction device 35 is brought close to the upper portion of the scallop 3 and the stalk 3 is sucked upward, the scallop 3 separated by the liquid is easily separated from the lower shell 2. Also in this case, as shown in FIGS. 8 and 9, the body (scallop: also referred to as a closed-shell muscle and a striated muscle) 3 extends from the outside of the closed-shell muscle (unstriated muscle portion) 60 of the shell 1 to the inner surface of the shell 2. When the liquid is ejected from the nozzle 32 toward the portion where the shell 2 adheres, the shell 2 is easily detached from the upper surface of the scallop 3 (the shell is easily opened). Also in this case, the ejection angle of the liquid from the nozzle 32 can be arbitrarily selected. The number of nozzles 32 can also be arbitrarily selected.

The scallop 3 separated from the shell 2 is a scallop suction device 3
5 and is sent out of the carrier 11.
The scallop 3 is washed with a washing liquid and then shipped as it is or after being frozen. As the cleaning liquid, ordinary water, ozone water, UV-treated water, or the like can be used.

(Second Embodiment of Shellfish Processing Method) FIGS.
(G) shows another shellfish treatment method. The details of the shellfish are illustrated in FIG. In this embodiment, as shown in FIG. 7 (a), the shell 1 is transported by the transport body 11, and as shown in FIG. 7 (b), the shell 2 is cut by the blade 23 to form the opening 5, and FIG. 7 (c). As shown in FIG. 7D, the upper shell 2 is removed from the scallop 3 by water pressure, and as shown in FIG.
As shown in FIG. 7E, the run 46 is sucked and removed by the accompanying part removing mechanism 10, and as shown in FIG. 7F, the string 47 is sucked and removed. Then, as shown in FIG. It is designed to be removed from the scallop 3. In FIG. 7, for convenience of explanation, the back 45 and the run 46 are displayed at a position shifted by 180 degrees, but the back 45 and the run 46 are actually located at a position shifted by approximately 90 degrees on the outer periphery of the shell 3 as shown in FIG. . Therefore, FIG.
In (f), the accompanying part removing mechanism 10 for sucking and removing the back 45 is removed.
And the auxiliary part removing mechanism 10 for sucking and removing the run 46, the auxiliary part removing mechanism 10 can be rotated back and forth by 90 degrees as shown in FIG. 7 (d, e).
When one of the back 45 and the run 46 is removed by suction, it is automatically rotated by 90 degrees to suck and remove the other.

A color discriminating sensor 48 is attached to the apparatus shown in FIG. The sensor 48 can determine the color of the orchid 46 to determine whether the orchid 46 is a male or female shell. By the way, male orchids are white, and female orchids are red. By performing this color discrimination, the orchid 46 can be separated into male and female shells and post-processed, which is convenient.

(Embodiment 1 of Shellfish Processing Apparatus) As shown in FIG. 3, the carrier 11 shown in FIG. 1 has a tray 20 mounted on a traveling body 36 such as a chain or another belt. The two receiving pieces 37 are configured as a pair, and a semicircular concave curved portion 38 is formed on the upper surface of each receiving piece 37,
Each of the receiving pieces 37 is attached to the traveling body 36 such that the concave curved portions 38 face each other. The transport body 11 automatically stops when it advances to a predetermined position, automatically starts running after a predetermined time has elapsed, and runs intermittently by a predetermined distance.

The holding member 22 shown in FIGS. 1 and 3 is in the form of an endless belt.
b, a pusher 41 for pushing downward in FIG. 3a) is arranged. The pusher 41 is attached to the lower traveling portion 40 of the holder 22.
Is disposed at a position opposite to the pan 20 with the pan 2 therebetween.
The shell 1 on the top 0 can be sandwiched and held between the shell 1 and the saucer 20. A spring 42 is disposed on the outer periphery of the shaft of the holder 22, and the spring 42 pushes the pusher 41 downward. When 1 enters, it is pushed back up.

The cutting tool 23 in FIG. 1 is a disc-shaped diamond cutter, which is disposed on both outer sides in the width direction of the carrier 11 and is rotated by a driving device (not shown). As the blade 23, a cutter of another material suitable for cutting the shell 2 or a cutter of another shape can be used. The blade 23 may be constantly rotating,
You may make it rotate only at the time of cutting.

The holding mechanism for the shell 1 shown in FIG. 5 has two arm-shaped first holding members 27 arranged on both outer sides of the tray 20, and the holding members 27 are moved inward by a driving device (not shown). Is closed, the inward locking piece 43 at the upper end of the holder 27 is locked to the upper edge of the lower shell 2 placed on the saucer 20, and the shell 2 is pressed against the saucer 20 and held. When the holding tool 27 is opened outward by the driving device, the locking piece 43 of the holding tool 27 is disengaged from the upper edge of the lower shell 2 and the pressing on the tray 20 is released. The holding mechanism may be another one.

As shown in FIG. 5, a vacuum suction device is used for the suction mechanism 50 of the accompanying part removing mechanism 10. The suction mechanism 50 evacuates the discharge passage 29 and the associated part removing mechanism (vacuum nozzle) 10 by operating the vacuum pump 51, and brings the suction port 28 of the associated part removing mechanism 10 closer to the associated part 4 attached to the shell 2. Then, the associated part 4 is sucked and removed from the shell 2. The associated part 4 sucked into the associated part removing mechanism 10 is put into the tank 30 through the discharge path 29. Tank 3
Moisture, fine dust, and the like contained in the auxiliary part 4 put into the chamber 0 are discharged to the outside of the tank 30 through the filter 31 in the tank 30. The associated parts 4 accumulated in the tank 30 are classified according to type as needed, and are used for other purposes or discarded. The first holder 27 is opened and closed left and right by a drive mechanism (not shown). Lower shell 2
When the associated part 4 is removed from the, the first holder 27 is opened and the holding of the shell 2 is released.

Although the suction port 28 of the attachment removing mechanism 10 shown in FIG. 5 is formed in a ring shape, the suction port 28 may be a simple cylinder like a scallop suction device 35 shown in FIG. It may be in the shape of a hole, a long hole, or the like, and the size of the hole may be any size that facilitates the suction of the associated portions 4 individually or simultaneously.

(Embodiment 2 of Shellfish Processing Apparatus) In FIG. 1, the opening 5 is formed only in the lower shell 2, but the opening may be formed in both upper and lower shells 2. The opening location may be other than the illustrated location. For example, two or more openings can be provided at an arbitrary location such as one end or both ends in the width direction of the shell 2. When two or more openings 5 are formed, the liquid ejected from one opening 5 escapes from the other opening 5 and the ejected liquid is less likely to collect inside the shell 2, and the shell 3
Is less likely to be damaged or flooded.

Although the disk-shaped rotary blade 23 is shown in FIG. 1, the blade 23 may have another shape or another type of motion (for example, reciprocating motion). For example, the cylindrical blade 23 may be rotated to make a round hole in the shell 2 to form the opening 5. Also, an opening can be formed by dropping a heavy object such as a hammer onto the shell 2 from above without damaging the shell 2 without using a blade. In this case, it is desirable that the generated fragments of the shell 2, the powder, and the like be suction-removed with a suction-removal device while being cut, or washed off with a liquid (for example, water).

In FIG. 1, the transport body 11 is intermittently moved, and the shell 2 is cut by the rotary blade 23 when stopped.
It is also possible to form the opening 5 during the traveling by moving the carrier 11 continuously, or to perform other processing. In that case, the running speed is set to be easy to work.

In FIG. 1, when the upper shell 2 is separated from the scallop 3, the shell 1 on the tray 20 can be sucked downward and held on the tray 20 by a suction-type holding mechanism built in the tray 20. However, the holding mechanism is automatically connected to the suction device installed at the stop position when traveling is stopped so that suction can be performed, and the suction device is automatically separated before starting movement. And convenient. When a suction-type holding mechanism is built in the pan 20, if a suction device is installed at each stop position and the suction device is automatically connected to or separated from the holding mechanism,
At the time of each stop, the shell on the tray 20 can be suction-held on the tray 20 without using the first holder 27 and the second holder 33. Further, instead of incorporating a suction-type holding mechanism in the pan 20, holding tools such as the first holding tool 27 and the second holding tool 33 can be provided in each step.

In the first embodiment, the upper shell 2 is opened, and then the associated portion 4 attached to the lower shell 2 is removed by suction. In the present invention, the opening 5 is formed and then the upper shell 2 is removed. Without opening the shell 2, the suction port (for example, a nozzle) 28 of the accompanying part removing mechanism 10 is applied to the opening 5 of the shell 1 to remove the shell 45 from the shell 45.
Only suction can be removed.

In FIG. 1 (d), the entire auxiliary part 4 such as a back, a string, a run, and the like is collectively sucked and removed by a single auxiliary part removing mechanism 10, but the auxiliary part 4 has a string,
It can also be suctioned and removed by type, such as orchid and uro. In particular, since the back is discarded and the other parts are commercialized, it is desirable that the back be removed by suction separately from the other parts. Therefore, separate suction and removal devices and suction mechanisms, such as a suction and removal device for urine removal and a suction and removal device for strings, and a suction and removal device for run, are used to suction attached parts by type. It can also be removed. Orchids are not throughout the year and only during the spawning season, so they are aspirated only at certain times.

FIGS. 1 (c), (e), FIGS. 4, 6 and 7
(C) The nozzles 25 and 34 in (g) can separate the shell 2 and the body 3 by ejecting a liquid from the outside of the closed shell muscle (unpatterned muscle portion) 60 of the shell 1 to the inside of the shell 2. And shellfish 1
Is installed outside the closed shell muscle (unpatterned muscle part) 60 side. The installation location can be another location.

[0044]

The shellfish treatment method of the present invention has the following effects. 1. Since a liquid is used to separate the shell and the scallop, the scallop is less likely to be damaged. 2. Since the scallop is not heated at all, the scallop can be taken out of the scallop without deterioration in quality, and is traded as a biological product on the market. 3. Even if shell fragments, chips, powder or the like adhered to the shell at the time of opening, the shell is washed with the liquid, so that the shell to which chips have not adhered can be taken out. 4. Since the associated portion is suction-removed, the removal of the associated portion is easy and reliable. Further, since the accompanying portion is not damaged, the commercial value of the accompanying portion does not decrease. 5. Since the shell is cut off with a liquid and the associated portion is suctioned off with a suction device, there is no need to touch the scallop or the associated portion after the shell is placed on the carrier, which is sanitary. 6. Liquid is sprayed from the outside of the closed shell muscle of the shell to the inside of the shell to separate the shell from the body, making it easier to separate,
Separation is possible even at low liquid pressure, and the shell is less likely to collapse or be damaged by liquid pressure, and the original shape of the shell is secured. Also,
Since the shell and the body are easily separated, the separating operation is also facilitated, and the working efficiency is good.

The shellfish processing apparatus of the present invention comprises a carrier for transporting shellfish, an opening mechanism for forming an opening in the shell of the shell, a suction removing device for sucking and removing ancillary parts from the shell, and a liquid jet between the shell and the shell. Since the separation mechanism is provided, the process of forming the opening, removing the associated portion, and taking out the scallop is automated, and significant labor saving and cost reduction can be achieved. In addition, a nozzle is provided outside the closed shell muscle (unpatterned muscle portion) to separate the shell from the body by spraying a liquid from outside the closed shell muscle (unpatched muscle portion) to the inside of the shell. It becomes easy to spray the liquid from the outside of the muscle (unpatterned muscle portion), and it is easy to separate the shell from the body.
