Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bivalve separation method and a bivalve separation method capable of efficiently separating a raw portion of a bivalve shell from a shell in a raw state.

[0002]

2. Description of the Related Art Generally, in order to separate a portion of a raw shell composed of bivalves, for example, a scallop scallop from a shell in a raw state, a thin knife-like tool called a shell is used. The joint between the scallop clam and the clam muscle consisting of the trabeculae and trabeculae closing the two scallop shells was cut by hand.

[0003] However, cutting and separating the scallop muscle from the shell by manual operation is inefficient, requires a great deal of labor and time, and requires a large amount of scallops to be landed at once. However, there is a problem that the freshness of the scallop is reduced unless a large number of personnel are put in and processed quickly.

[0004] Therefore, various proposals have conventionally been made to efficiently separate the portion eaten by the original shell consisting of bivalves from the shell.

For example, Japanese Patent Application Laid-Open No.
As described in JP-A-3-87937, the tip of the scallop is cut with a cutter or the like to form an opening at the tip of the scallop, and a blade inserted from this opening is cut along the inner surface of one of the shells. By proceeding while sliding,
In some cases, the joint between the closed shell muscle that closes the two shells and one of the shells is cut to expand the shell.

As another example, see, for example,
0-3899, JP-A-52-13900,
As described in Japanese Patent Application Laid-Open No. Hei 5-3751, the scallop is heated by heating means to expand the shell, and thereafter the scallop is separated from the other shell.

[0007] However, in the above-mentioned conventional scallop in which the tip of the scallop is cut with a cutter or the like, the scallop, which is the main edible portion, can be taken out of the shell in a raw state, but cutting debris adheres to the scallop. In addition, there is a problem that a great deal of labor and time are required for post-processing such as removing a damaged scallop or removing cutting chips from the scallop. Furthermore, the scallop is separated from the shell by manual work such as cutting the joint between the shell and the musculature, which requires a great deal of effort to separate the scallop from the shell. There is also a problem in that it cannot be efficiently separated from the shell in the raw state.

In a conventional scallop shell which is heated by a heating means to expand the shell, although the mouth of the shell can be easily opened, the surface of the scallop, particularly the surface of the scallop located on the heating side, is not easy to open. In many cases, the color changed to white, so-called boiled, and the appearance quality was deteriorated, and the quality for use in raw food could not be maintained. That is, in the case of using the conventional heating means, there was a problem that there were few things that could be supplied as raw food from a large number of scallops actually taken out of the scallop.

[0009] Conventionally, the separation of the scallop from the shell after the shell has been spread has been performed manually, which requires a great deal of labor to separate the scallop from the shell, and the scallop is efficiently separated from the shell. There was also a problem that it could not be separated.

Further, when the scallop is separated from the expanded shell by using a knife-like tool called the above-mentioned scallop, the shell and the scallop can be manually or mechanically operated by an automatic machine. And the surface of the separated scallop becomes a jagged cut surface, deteriorating the appearance quality, and even if the blade of a knife-like tool is operated along the inner surface of the shell, There is a problem that the inner surface of the shell cannot completely follow the inner surface of the shell, and a portion of the closed-shell muscle remains in the concave portion of the shell, resulting in poor yield.

Further, by cutting the joint between the shell and the scallop, the stalk separated from the shell is easy to absorb moisture from the cut surface since the cut surface is exposed. For this reason, the water used in the washing operation to remove extraneous matter, such as fine internal organs, attached to the closed-shell muscle in order to make the scallop a food is absorbed into the inside of the scallop, and the taste deteriorates. When refrigerated is stored, there is a problem that when thawed, umami components flow out together with the absorbed water.

[0012] Therefore, there is a need for a product that can be efficiently separated from shells while maintaining the quality of using the scallops for raw eating.

The present inventors have developed a patented invention according to Japanese Patent No. 2795634 as a material capable of efficiently separating the scallop from the shell while maintaining the quality for use in raw food. In this patent invention, one surface of the bivalve is heated so that the part to be eaten is in a raw state, and the shell is not spontaneously opened, and then the shell is forcibly opened. .

According to the present invention, it is possible to efficiently separate the edible portion from the shell while keeping the edible portion such as the scallop in a raw state.

[0015]

In recent years, there has been a demand for a bivalve separation method and apparatus capable of separating a part to be eaten from a shell more efficiently than the above-mentioned patented invention.

The present invention has been made in view of the above-mentioned points, and allows the edible portion to be kept in a raw state, and further separates the edible portion from the shell more efficiently than conventional ones.
It is an object of the present invention to provide a clam separation method and a separation apparatus.

[0017]

In order to achieve the above-mentioned object, the features of the bivalve separation method of the present invention according to claim 1 are as follows.
A portion of the outer shell of the first shell of the bivalve shell in a closed state corresponding to the connection with the scallop and the trabecula is instantaneously heated, and both shells in the still closed state are forcibly forced. An opening is formed, and a cutting means is inserted through the opening to peel off the scallop from the first shell, and the trabecula is cut at a connection portion with the first shell, so as to be outside the second shell of the bivalve. Momentarily heat the site corresponding to the connection with the scallop and small pillar on the surface,
The present invention is characterized in that the scallop is peeled off from the second shell by the cutting means, and the small pillar is cut at a connection portion with the second shell. And by adopting such a configuration, the cutting means cuts a small pillar having a larger adhesive strength with the shell than the shell, and reduces the energy for heating the shell. And the shell can be separated more efficiently than the conventional one.

A feature of the bivalve separation method according to the present invention according to claim 2 is that the bivalve clamshell in a closed state corresponds to the connecting portion between the outer surface of the first shell and the scallop and the small pillar. After the portion is instantaneously heated, the outer surface of the first shell is cooled with cold water, and water vapor is sprayed on the outer surface of the first shell at the portion corresponding to the connecting portion of the trabecula. The point is that both shells in the closed state are forcibly opened. And by adopting such a configuration,
By heating the pillars while cooling the outer surface of the first shell, the pillars can be easily peeled from the shells while maintaining freshness of the pillars.

A feature of the bivalve separation method of the present invention according to claim 3 is that both shells in a closed state are forcibly urged in a direction of opening, and the first shell of the bivalve is urged. The portion corresponding to the connecting portion between the outer surface of the shell and the trabecula is heated, and both shells are forcibly opened so that the first shell and the trabecula and the trabecula are completely peeled off. A portion of the outer surface of the second shell corresponding to the connection with the scallop and the trajectory is instantaneously heated, and the scallop is separated from the second shell by cutting means, and the trabecula is removed from the second shell. In that it is cut off at the connection part. And by adopting such a configuration, the outer surface of the first shell of the two shells urged in the opening direction is heated, so that the scallop and the trabecula gradually move from the first shell. As a result, heat is not applied to the portion of the scallop separated earlier from the first shell, so that the freshness of the scallop can be favorably maintained.

A feature of the bivalve separation method of the present invention according to claim 4 is that a portion of the outer surface of the second shell of the bivalve, which corresponds to the connection with the scallop and the trajectory, is instantaneously heated. Later, while cooling the outer surface of the second shell with cold water, water vapor is sprayed on the outer surface of the second shell corresponding to the connection portion with the small column, and then the cutting means removes water from the second shell. The present invention is characterized in that the scallop is peeled off and the stilt is cut at a connection portion with the second shell. And, by adopting such a configuration, by heating the small pillars while cooling the outer surface of each shell, the freshness of the shells can be maintained more favorably, and the small pillars can be easily separated from the shells. .

According to a fifth aspect of the present invention, the bivalve separating apparatus according to the present invention is characterized in that a portion corresponding to a connection portion between the outer surface of each shell of the bivalve shell in a closed state and a scallop and a small pillar is provided. Heating means for instantaneously heating, shell holding means provided with a pair of suction pads which can be adsorbed to the outer surface of each shell of the bivalve, respectively, and which can be relatively close to and separated from each other; And a cutting means for cutting the small pillar at a connection portion with the shell. And, by adopting such a configuration, a small pillar having a larger bonding strength with the shell than the shell is cut by the cutting means, and the energy of the heating means for heating the shell is reduced, so that the main part is eaten. While keeping the scallop in a raw state, the scallop and the shell can be separated more efficiently than conventional ones.

According to a sixth aspect of the present invention, the bivalve separating apparatus according to the present invention is characterized in that the heating means includes a partial heating means for injecting water vapor onto a surface of the first shell corresponding to a connection with the small pillar. And a cooling means for cooling the surface of the first shell. And by adopting such a configuration, by heating the small pillars while cooling the outer surface of the first shell, it is easy to peel the small pillars from the shell while keeping the freshness of the shell even better. it can.

According to a seventh aspect of the present invention, the bivalve separating apparatus according to the present invention is characterized in that the heating means includes a partial heating means for injecting steam to the surface of the second shell corresponding to the connecting portion of the small pillar. And a cooling means for cooling the surface of the second shell. And, by adopting such a configuration, by heating the small pillars while cooling the outer surface of each shell, the freshness of the shells can be maintained more favorably, and the small pillars can be easily separated from the shells. .

A feature of the bivalve separating apparatus of the present invention according to claim 8 resides in that a tip portion of the heating means is arranged in each suction pad of the shell holding means. By adopting such a configuration, the outer surfaces of the first shell can be partially separated from the first shell if the outer surfaces of the first shell are heated while the outer surfaces of the first shell are urged by the suction pads in the opening direction. Since heat is not applied to the portion of the scallop thus made, freshness of the scallop can be maintained more favorably.

[0025]

1 to 5 show a first embodiment of a bivalve separating apparatus according to the present invention. In this embodiment, in order from the upstream side in the scallop transport direction,
A shell washing means, a first heating means, a shell holding means, a first cutting means, a shell separating means, a viscera separating means, a second heating means, a second cutting means, a scallop collecting means means, etc. While the scallop is conveyed along the means, each means performs various actions on the scallop. Of these means, only the main part of the present invention will be described. Note that the configuration of which the description is omitted here conforms to that described in the above-mentioned Patent Publication No. 2795634.

In FIG. 1 to FIG.
1 shows a scallop carrier that can transport a plurality of scallops 1 as an example of a single shell in a state of being placed in an array, and each of the scallops 1 partially fits into the scallop carrier 10. A plurality of openings (not shown) smaller than the planar shape of the scallop 1 to be obtained are formed. The scallop carrier 10 is intermittently carried by a driving means such as a motor (not shown).

FIG. 1 shows a first shell 2A located above each scallop 1 placed on the scallop carrier 10.
The first heating means 11 for heating is shown.

The first heating means 11 has a downward heating head 12 which can be moved up and down by a lifting mechanism (not shown). The heating head 12 is connected to a steam supply source (not shown) so as to be able to jet steam. It has become. Note that hot water may be injected from the heating head 12. The caliber of the heating head 12 is smaller than the plane shape of the scallop 1, and the scallop 3
In addition, the portion of the first shell 2A corresponding to the connecting portion with the small pillar 4 (FIG. 5) can be mainly heated.

FIG. 2 shows a pair of suction pads 16A and 16B that are respectively adsorbed to the shells 2A and 2B of the scallop 1 placed on the scallop carrier 10 and hold the shells 2A and 2B. The first shell holding means 15 provided with is shown.

Each suction pad 16 of the shell holding means 15
A and 16B are independently moved up and down, rotated and horizontally moved by a drive mechanism (not shown). Each of the suction pads 16A and 16B is connected to a vacuum pump (not shown) so that the inside of each of the suction pads 16A and 16B is set to a negative pressure to suck and hold the corresponding shell 2A and 2B. Therefore, in a state where the lower suction pad 16B sucks and holds the second shell 2B positioned below, the upper suction pad 16A rises while sucking and holding the first shell 2A positioned above. Then, the first shell 2A of the scallop 1 is rotated to be separated from the second shell 2B, and the scallop 1 that has been closed can be forcibly opened.

In the vicinity of the shell holding means 15,
As shown in FIGS. 3 to 5, a flat plate-shaped cutter 17 is shown as a cutting means for separating or cutting off the scallop 3 and the small pillar 4 of the scallop 1 from the connection with the first shell 2A. It is arranged to be able to advance and retreat by a drive mechanism that does not. The cutter 17 can slide along the inner surface of the first shell 2A.

Further, the second shell 2B of each scallop 1 placed on the scallop carrier 10 is heated in a state where the scallop 3 and the small pillars 4 are separated from the first shell 2A. A second heating means (not shown) is provided below the scallop carrier 10. The second heating means has an upward heating head (not shown) that can be moved up and down by an elevating mechanism (not shown). The heating head is connected to a supply source of steam or hot water (not shown) to supply steam or hot water. It can be sprayed.
The diameter of the heating head is also smaller than the planar shape of the scallop 1 like the heating head 12, and the second shell 2B corresponding to the connection portion of the scallop 1 with the scallop 3 and the scallop 4 is formed. The part can be heated mainly. Since the heating head of the second heating means has a structure in which the heating head 12 is turned upside down, its illustration is omitted.

Further, in the transport direction of the scallop 1, downstream of the second heating means, the second scallop 1 is adsorbed on the second shell 2 B of each scallop 1 placed on the scallop transport body 10. A second shell holding means (not shown) including a suction pad (not shown) for holding the second shell 2B is shown.

The suction pad of the second shell holding means is raised and lowered by a lifting mechanism (not shown).
Further, the suction pad is connected to a vacuum pump (not shown) so that the inside of the suction pad is set to a negative pressure to suck and hold the second shell 2B. The second shell holding means is provided on the upper first suction pad 16 of the first shell holding means 15.
The other configuration is similar to that of the first shell holding means 15 except that it does not have A, so that its illustration is omitted.

In the vicinity of the second shell holding means,
A flat-plate-shaped cutter (not shown) as a cutting means for separating or cutting the scallop 3 and the small pillar 4 of the scallop 1 from the connection with the second shell 2B can be advanced and retracted by a drive mechanism (not shown). It is arranged in. The tip of the cutter is inclined downward from the cutter 17 so that the second
Although it can slide along the inner surface of the shell 2B, the other configuration is similar to the cutter 17, so that the illustration is omitted.

Next, the operation of the first embodiment of the present invention having the above-described configuration will be described.

First, a plurality of scallops 1 are placed on a scallop carrier 10.
The scallop carrier 10 is transported to a position facing the first heating means 11 and stopped there. In this position, the respective heating heads 12 of the first heating means 11 arranged so as to correspond to the respective scallops 1 are simultaneously lowered, and the lower ends of the respective heating heads 12 are positioned near the first shell 2A of the scallop 1. When positioned, the lowering of each heating head 12 is stopped. Then, as shown in FIG. 1, steam is instantaneously injected from each heating head 12 toward the first shell 2A. Then, the connecting portions of the scallop 3 and the small pillars 4 connected to the inner surface of the first shell 2A are weakened by the heat of the steam, and are easily peeled off from the inner surface of the shell 2A. This phenomenon is remarkable in the shell 3 whose adhesive strength with the shell 2A is weaker than that of the small pillar 4.

Thereafter, as shown in FIG. 2, the scallop carrier 10 is transported to a position facing the first shell holding means 15 and stopped there. During this time, the heating heads 12 are raised.

The suction pads 16A, 16B of the first shell holding means 15 are pressed against the shells 2A, 2B of the corresponding scallop 1, respectively, while the suction pads 16A, 16B are pressed.
From the first shell 2 on the suction pad 16A.
A is adsorbed, and the second shell 2B is adsorbed on the adsorption pad 16B.

In such a state, the second shell 2B
Is stopped, and only the suction pad 16A that is sucking the first shell 2A is raised. Then, the adhesion of the shell 3 and the small pillar 4 to the first shell 2A is reduced by the above-mentioned injection of water vapor from the heating head 12, so that the suction pad 16
As A is raised, the scallop 3 will at least partially detach from the first shell 2A, and the trabecula 4 will extend.

Therefore, as shown in FIG.
The cutter 17 is inserted between the two shells 2A and 2B which are opened by the rotation of the first shell 2A with the rise and rotation of the shell 6A,
The cutter 17 is slid along the inner surface of the first shell 2A. Then, as shown in FIGS. 4 and 5, the shell 3 is peeled off from the inner surface of the shell 2A by the cutter 17 and the small column 4 is cut in the vicinity of the connection with the first shell 2A.

As a result, each of the scallop 3 and the stilt 4 is separated from the first shell 2A. Therefore, the suction pad 16A that is holding the first shell 2A is further rotated. In this state, when the transport of the scallop transport body 10 is resumed, the baffle plate (not shown) of the shell separating means comes into contact with the inclined first shell 2A, and finally the first shell 2A is moved. Is separated from the second shell 2B to which the shell 3 and the small pillar 4 are adhered.

Next, the suction of the second shell 2B by the suction pad 16B is continued, and the scallop carrier 10 is transported to a position facing the internal organ separating means (not shown) and stopped. Then, the vacuum head communicating with the vacuum pump sucks and removes the internal organs 5 of the scallop 1 whose upper part is exposed.

Thereafter, the scallop transport body 10 is transported to a position facing the second heating means (not shown) and stopped. In this position, the respective heating heads of the second heating means arranged so as to correspond to the respective scallops 1 are simultaneously raised, and when the upper ends of the respective heating heads are located near the second shell 2B of the scallop 1, Stop raising each heating head. And
Water vapor is instantaneously injected from each heating head toward the second shell 2B. Then, the respective connecting portions of the scallop 3 and the small pillars 4 connected to the inner surface of the second shell 2B are weakened by the heat of the steam, and are easily separated from the inner surface of the shell 2B.

Thereafter, the scallop transport body 10 is transported to a position facing the second shell holding means (not shown) and stopped.

Then, while the suction pads of the second shell holding means are pressed against the corresponding shells 2B of the scallop 1, air is sucked from the suction pads, and the second shells 2B are sucked to the suction pads.

In such a state, a cutter (not shown) of the second cutting means is inserted along the inner surface of the shell 2B, and the cutter is slid along the inner surface of the second shell 2B. Then, the cutter 3 is peeled off from the inner surface of the shell 2B by the cutter, and the pillar 4 is separated from the second shell 2B.
It is cut in the vicinity of the connection with B.

As a result, both the shell 3 and the small pillars 4 are separated from the second shell 2B, and are placed on the second shell 2B. Therefore, the suction of the second shell 2B by the suction pad 16B is continued, and the scallop transport body 10 is transported to a position facing the scallop collecting means (not shown) and stopped. Then, the vacuum head communicating with the vacuum pump sucks and collects the scallop 3 and the small pillar 4 of the scallop 1 whose upper part is exposed.

The scallop 3 thus maintained in a raw state
Can be efficiently separated and recovered from both shells 2A and 2B. Moreover, when the scallop 1 is opened with the small pillar 4 having a strong adhesive force to the shells 2A and 2B, the shells 2 are heated by heat.
Since the small pillars 4 are intentionally cut without heating until they are separated from A and 2B, it is possible to take out the shell pillars 3 which maintain the raw state very efficiently.

FIGS. 6 to 10 show a second embodiment of the bivalve separating apparatus according to the present invention.

In the present embodiment, the shells 2A and 2B are heated only by the first heating means 11 and the second heating means (not shown) in the first embodiment described above, and thereafter no special heating is performed. On the other hand, in the present embodiment, the outer surfaces of the shells 2A and 2B at the portions corresponding to the connection portions with the small pillars 4 are further heated.

Hereinafter, only the configuration different from the first embodiment will be described. The same or corresponding components as those in the first embodiment are denoted by the same reference numerals in the drawings, and description thereof will be omitted.

In this embodiment, an auxiliary heating means 20 shown in FIG. 7 is disposed downstream of the first heating means 11 in the direction of transport of the scallop 1. This auxiliary heating means 2
Numeral 0 has a heating head 21 for heating only a portion of the first shell 2A of the scallop 1 corresponding to the connection portion with the small column 4 with water vapor. The heating head 21 is connected to a steam supply source (not shown) so as to be able to jet steam. Note that hot water may be injected from the heating head 21. In addition, this heating head 21
A cooling head 22 for cooling the first shell 2A of the scallop 1 at the time of heating by the heating head 21 is disposed in the vicinity of. The cooling head 22 is connected to a cooling water supply source (not shown) so as to be able to spray cooling water.

Next, the operation of the second embodiment of the present invention having the above-described configuration will be described.

First, a plurality of scallops 1 are placed on a scallop carrier 10.
The scallop carrier 10 is transported to a position facing the first heating means 11 and stopped there. In this position, the respective heating heads 12 of the first heating means 11 arranged so as to correspond to the respective scallops 1 are simultaneously lowered, and the lower ends of the respective heating heads 12 are positioned near the first shell 2A of the scallop 1. When positioned, the lowering of each heating head 12 is stopped. Then, as shown in FIG. 6, water vapor is instantaneously injected from each heating head 12 toward the first shell 2A. Then, the connecting portions of the scallop 3 and the small pillars 4 connected to the inner surface of the first shell 2A are weakened by the heat of the steam, and are easily peeled off from the inner surface of the shell 2A.

Thereafter, the scallop carrier 10 is transported to a position facing the auxiliary heating means 20 and stopped there. During this time, the heating heads 12 are raised.

Then, as shown in FIG.
In a state in which the cooling water is being sprayed from 2 to the shell 2A of each scallop 1, water vapor is sprayed from the heating head 21 to a portion of the first shell 2A corresponding to the connection with the small column 4. Then, as shown in FIG. 8, the high-pressure steam pushes the cooling water W flowing down the portion of the first shell 2A corresponding to the connection portion with the small column 4 so as to push the first shell 2A with the steam S. It will be heated. The heating time is not instantaneous, but on the order of several seconds.

As a result, the connection between the small pillar 4 and the first shell 2A is further heated, so that the small pillar 4 is further weakened and easily peeled from the shell 2A. On the other hand, while the pillar 4 is further heated, the shell 2
Since the other outer surface of A is cooled by the cooling water, the freshness of the scallop 3 is further improved.

Thereafter, the scallop carrier 10 is transported to a position facing the first shell holding means 15 and stopped there. Then, both the suction pads 16A of the first shell holding means 15,
The air is sucked from the suction pads 16A and 16B while the 16B is pressed against the shells 2A and 2B of the corresponding scallop 1, respectively, and the first shell 2A is sucked on the suction pad 16A as shown in FIG. Second on the suction pad 16B
Is absorbed.

In such a state, the second shell 2B
Is stopped, and only the suction pad 16A that is sucking the first shell 2A is raised. Then, the adhesive strength of the scallop 3 to the first shell 2A is reduced due to the above-described injection of water vapor from the heating head 12, and the small stilt 4 has the two heating heads 12,
Since the adhesive force between the first shell 2A and the first shell 2A is further reduced by the heating by the steam from the steam generator 21, both the scallop 3 and the small pillar 4 are at least separated from the first shell 2A by raising the suction pad 16A. Partial peeling will occur.

Therefore, the first shell 2A is rotated and opened as the suction pad 16A is raised and rotated.
Insert a cutter (not shown) of the cutting means between A and 2B,
The cutter is slid along the inner surface of the first shell 2A. Then, the cutter 3 and the small pillar 4 are separated from the inner surface of the shell 2A by the cutter (FIG. 10).

As a result, both of the scallop 3 and the stilt 4 are separated from the first shell 2A. Therefore, the suction pad 16A that is holding the first shell 2A is further rotated. In this state, when the transport of the scallop transport body 10 is resumed, the baffle plate (not shown) of the shell separating means comes into contact with the inclined first shell 2A, and finally the first shell 2A is moved. Is separated from the second shell 2B to which the shell 3 and the small pillar 4 are adhered.

Next, the suction of the second shell 2B by the suction pad 16B is continued, and the scallop transport body 10 is transported to a position facing the internal organ separating means (not shown) and stopped. Then, the vacuum head communicating with the vacuum pump sucks and removes the internal organs 5 of the scallop 1 whose upper part is exposed.

Thereafter, the scallop carrier 10 is transported to a position facing the second heating means (not shown) and stopped. In this position, the respective heating heads of the second heating means arranged so as to correspond to the respective scallops 1 are simultaneously raised, and when the upper ends of the respective heating heads are located near the second shell 2B of the scallop 1, Stop raising each heating head. And
Water vapor is instantaneously injected from each heating head toward the second shell 2B. Then, the respective connecting portions of the scallop 3 and the small pillars 4 connected to the inner surface of the second shell 2B are weakened by the heat of the steam, and are easily separated from the inner surface of the shell 2B.

Next, the scallop carrier 10 is moved to the second shell 2.
The sheet is transported to a position opposite to the auxiliary heating means for B (not shown) and stopped.

Then, while cooling water is being sprayed from the cooling head (not shown) to the shell 2A of each scallop 1, the connection from the heating head (not shown) to the small pillar 4 in the second shell 2B is made. Inject steam into the part corresponding to the part. Then, the first shell 2B is heated by the high-pressure steam so that the cooling water flowing down the portion corresponding to the connection portion with the small column 4 in the second shell 2B is pushed away. This heating time is also not instantaneous but about several seconds.

As a result, the connecting portion of the small pillar 4 with the second shell 2B is further heated, so that the small pillar 4 is further weakened and is more easily peeled from the shell 2B. . On the other hand, while heating the pillar 4 further,
Since the other outer surface of the shell 2B is cooled by the cooling water, the freshness of the scallop 3 is further improved.

Further, the scallop carrier 10 is transported to a position facing the second shell holding means (not shown) and stopped.

Then, air is sucked from each suction pad while each suction pad of the second shell holding means is pressed against the corresponding shell 2B of the corresponding scallop 1, and the second shell 2B is sucked to the suction pad.

In such a state, a cutter (not shown) of the second cutting means is inserted along the inner surface of the shell 2B, and the cutter is slid along the inner surface of the second shell 2B. Then, the cutter 3 and the small pillar 4 are
Is peeled off from the inner surface of the shell 2B.

As a result, both the shell 3 and the small pillars 4 are separated from the second shell 2B, and are placed on the second shell 2B. Therefore, the suction of the second shell 2B by the suction pad 16B is continued, and the scallop transport body 10 is transported to a position facing the scallop collecting means (not shown) and stopped. Then, the vacuum head communicating with the vacuum pump sucks and collects the scallop 3 and the small pillar 4 of the scallop 1 whose upper part is exposed.

In this way, the scallop 3 that has been maintained in a more raw state than in the first embodiment can be efficiently attached to both shells 2A, 2A.
B and can be recovered separately.

FIGS. 11 to 14 show a third embodiment of the bivalve separating apparatus according to the present invention.

That is, as shown in detail in FIG. 12, a heating head 12 that is connected to a steam supply source (not shown) and can spray steam is arranged inside the suction pad 26A that is connected to a vacuum pump (not shown). Has been established.

In the present embodiment, the separation of the scallop 3 and the trabecule 4 from the first shell 2A of the scallop 1 is performed by heating the heating head 12 and using the suction pads 26A and 16B to separate the scallop 2A and 2B. Since the expansion is performed, the cutter 17 for peeling off the scallop 3 and the trajectory 4 from the first shell 2A of the scallop 1 is not required.

Since the separation of the scallop 3 and the small pillar 4 from the second shell 2B of the scallop 1 is performed in the same manner as in the first embodiment or the second embodiment, the same configuration as in both embodiments is used. Have requirements.

Next, the operation of the third embodiment of the present invention having the above-described configuration will be described.

First, a plurality of scallops 1 are placed on the scallop carrier 10.
And the scallop carrier 10 is placed in the first shell holding means 1.
The sheet is transported to a position facing 5 and stopped. In this position, the two suction pads 26A of the first shell holding means 15,
The air is sucked from the suction pads 26A, 16B while the 16B is pressed against the shells 2A, 2B of the corresponding scallop 1, respectively, and as shown in FIG.
And the second shell 2B is adsorbed to the adsorption pad 16B. At this time, the suction pad 26A that is adsorbing the first shell 2A is attached to the scallop 3 and the stilt 4
Surrounding the first shell 2A at a portion corresponding to the connection portion.

And sprays steam toward the first shell 2A. Then, the shell 2 of the scallop 3 and the trajectory 4 is heated by the heat of the steam.
A weakened at the connection portion with the suction pads 26A, 16B
The two shells 2A, 2B urged by the opening gradually expand. Then, as shown in FIG. 13, the scallop 3 gradually peels off from the first shell 2A. At this time, since the heat of the steam is hardly applied to the scallop 3 at the portion peeled off from the first shell 2A, the shell 3 is kept in a raw state.

Finally, as shown in FIG. 14, the entirety of the scallop 3 and the stilt 4 is separated from the first shell 2A and separated. Therefore, the suction pad 26A that is sucking the first shell 2A is further rotated. In this state, when the transport of the scallop transport body 10 is resumed, the baffle plate (not shown) of the shell separating means abuts the first shell 2A in the inclined state,
Eventually, the first shell 2A is separated from the second shell 2B to which the scallop 3 and the stilt 4 are adhered.

Next, the suction of the second shell 2B by the suction pad 16B is continued, and the scallop carrier 10 is transported to a position facing the internal organ separating means (not shown) and stopped. Then, the vacuum head communicating with the vacuum pump sucks and removes the internal organs 5 of the scallop 1 whose upper part is exposed.

Thereafter, the scallop transport body 10 is transported to a position facing the second heating means (not shown) and stopped. In this position, the respective heating heads of the second heating means arranged so as to correspond to the respective scallops 1 are simultaneously raised, and when the upper ends of the respective heating heads are located near the second shell 2B of the scallop 1, Stop raising each heating head. And
Water vapor is instantaneously injected from each heating head toward the second shell 2B. Then, the respective connecting portions of the scallop 3 and the small pillars 4 connected to the inner surface of the second shell 2B are weakened by the heat of the steam, and are easily separated from the inner surface of the shell 2B.

Thereafter, the scallop carrier 10 is transported to a position facing the second shell holding means (not shown) and stopped there.

Then, air is sucked from each suction pad while each suction pad of the second shell holding means is pressed against the corresponding shell 2B of the scallop 1, and the second shell 2B is sucked to the suction pad.

In such a state, a cutter (not shown) of the second cutting means is inserted along the inner surface of the shell 2B, and the cutter is slid along the inner surface of the second shell 2B. Then, the cutter 3 is peeled off from the inner surface of the shell 2B by the cutter, and the pillar 4 is separated from the second shell 2B.
It is cut in the vicinity of the connection with B.

As a result, both the scallop 3 and the small pillar 4 are separated from the second shell 2B, and are placed on the second shell 2B. Therefore, the suction of the second shell 2B by the suction pad 16B is continued, and the scallop transport body 10 is transported to a position facing the scallop collecting means (not shown) and stopped. Then, the vacuum head communicating with the vacuum pump sucks and collects the scallop 3 and the small pillar 4 of the scallop 1 whose upper part is exposed.

The scallop 3 thus maintained in a raw state
Can be efficiently separated and recovered from both shells 2A and 2B.

The present invention is not limited to the embodiment described above, and various modifications can be made as needed.

As described above, according to the bivalve separating method and the separating apparatus of the present invention, the edible portion and the shell are further maintained than the conventional one while keeping the edible portion in a raw state. It can be separated efficiently.

That is, according to the bivalve separation method of the present invention, the portion corresponding to the connecting portion between the outer shell of the first shell of the bivalve shell in a closed state and the scallop and the trajectory is instantaneously formed. The heated and still closed shells are forcibly opened, cutting means are inserted through the openings to peel off the scallop from the first shell and connect the trabeculae to the first shell. Cut at the part, and instantaneously heat the portion corresponding to the connection with the scallop and trabecula on the outer surface of the second shell of the bivalve,
The cutting means peels off the scallop from the second shell and cuts the trajectory at the connection with the second shell. By cutting, the energy for heating the shell is reduced, and the shell, which is the main eating site, is kept in a raw state, and the shell and the shell can be separated more efficiently than the conventional one.

[0093] The first of the bivalves with the shell closed is
After instantaneously heating a portion of the outer surface of the shell corresponding to the connection with the scallop and the trajectory, cooling the outer surface of the first shell with cold water, and a portion corresponding to the connection of the trajectory. By injecting steam into the outer surface of the first shell of the above, and then forcibly opening both shells that are still closed, by heating the small pillars while cooling the outer surface of the first shell, While maintaining the freshness of the scallop, the stilt can be easily separated from the shell.

Further, both shells in the closed state are forcibly urged in the opening direction, and the outer shell of the first shell of the bivalve corresponds to the portion of the outer shell corresponding to the connecting part with the scallop and the small pillar. Is heated to forcibly open both shells so that the first shell and the scallop and trabecula are completely peeled off.
A portion of the outer surface of the shell corresponding to the connection with the scallop and the trajectory on the outer surface of the shell is instantaneously heated, the scallop is separated from the second shell by cutting means, and the trabecula is separated from the second shell. When the connection is cut, the outer surface of the first shell of the two shells urged in the opening direction is heated, so that the scallop and the trabecula are gradually separated from the first shell. Therefore, since heat is not applied to the portion of the scallop separated early from the first shell, freshness of the scallop can be favorably maintained.

Further, after instantaneously heating a portion of the outer surface of the second shell of the bivalve shell corresponding to the connection with the scallop and the small pillar, the outer surface of the second shell is cooled with cold water. At the same time, water vapor is sprayed on the outer surface of the second shell corresponding to the connecting portion with the small column, and then the cutting column separates the small column from the second shell and cuts the small column into the second shell. By cutting at the connection portion with the shell, by heating the column while cooling the outer surface of each shell, the column can be more easily peeled off from the shell while maintaining the freshness of the column more favorably.

On the other hand, the bivalve separation apparatus of the present invention instantaneously heats a portion of the outer surface of each of the shells of the bivalve shell in a closed state, which corresponds to the connection between the shell and the column. Heating means for; and a shell holding means having a pair of suction pads capable of being adsorbed to and separated from the outer surface of each shell of the bivalve shell, respectively, and separating the scallop from the shell, Cutting means for cutting the trabeculae at the joint with the shell, so that the cutting means cuts the trabecula having a greater adhesive strength with the shell than the scallop, thereby reducing the energy of the heating means for heating the shell. It is possible to separate the scallop and the shell more efficiently than before by keeping the raw state of the scallop, which is the main eating site, by reducing the number of stalks.

[0097] Further, the heating means includes a partial heating means for injecting steam into the surface of the first shell corresponding to the connecting portion with the small pillar, and cooling the surface of the first shell. If the cooling means is further provided, by heating the small columns while cooling the outer surface of the first shell, the freshness of the shells can be maintained more favorably, and the small columns can be easily separated from the shells. .

Further, the heating means includes a partial heating means for injecting steam to the surface of the second shell corresponding to the connecting portion of the small pillar, and cools the surface of the second shell. If a cooling means is further provided, by heating the small pillars while cooling the outer surface of each shell, the freshness of the shells can be maintained more favorably, and the small pillars can be easily separated from the shells.

Further, if the tip of the heating means is disposed in each suction pad of the shell holding means, the first shell is urged by both suction pads in the opening direction. By heating the outer surface of the shell, heat is not applied to the portion of the shell partially separated from the first shell, so that the freshness of the shell can be maintained more favorably.
