DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for efficiently removing a midgut gland in order to effectively use a scallop mantle, which has become an enormous amount of waste and is difficult to dispose of, as a food. And equipment.

[0002]

2. Description of the Related Art As shown in FIG. 1, a scallop has a mantle membrane 2 and a midgut gland 3 around a scallop 1 as shown in FIG. Scallop 1
Is removed, the mantle 2 and the midgut gland 3 remain. Generally, the mantle 2 is called a "string" and the midgut gland 3 is called a "uro".
The mantle 2 removed from the scallop 1 can be processed into food as a knob or the like when the midgut gland 3 is removed. Mantles that do not remove the midgut gland cannot be eaten as food. 12 midgut glands
This is because they cannot be eaten except for months to February.

[0003] At present, the mantle separated from the scallop of the scallop is almost completely discarded, and the amount thereof is enormous. The reason that the mantle cannot be effectively used as food is that the midgut gland cannot be separated efficiently. Since a huge amount of mantle is discarded by incineration or the like, considerable cost is required for disposal. A very limited amount of mantle has been manually processed to remove the midgut gland and processed into food items such as knobs. Despite the fact that the mantle becomes a tasty knob when the midgut gland is removed, the actual situation is that enormous costs are discarded because no efficient removal technique has been developed.

[0004] In order to effectively utilize a huge amount of mantle as food, a method for efficiently separating the midgut gland is desired in the scallop industry. To achieve this,
An apparatus for removing a midgut gland by image processing has been developed (Japanese Patent Laid-Open No. 5-176727). The device described in this publication calculates a signal input from a camera by an image processing device, recognizes a boundary between a scallop, a mantle, and a midgut gland, and jets a water jet along the recognized boundary. , Cut at the boundary.

[0005]

The apparatus described in this publication has a drawback that it is difficult to process a large amount of bark in a short time. It separates and transports the bark, and transfers the bark to each camera and inputs it to a computer, etc.
This is because a water jet is jetted and cut along the recognized boundary. In addition, this apparatus has a disadvantage in that a mechanism for arranging and transporting the bark, a part for processing the bark, and a part for moving and cutting the water jet to an accurate position are expensive and cannot be manufactured at low cost.

Furthermore, the device of this structure can recognize and separate the boundary when the mantle and midgut gland are connected to the scallop, but can separate the mantle and midgut gland when separated from the scallop. The disadvantage is that the midgut gland cannot be separated from the mantle in recognition of the border. In the processing of scallop, the mantle and the midgut gland are separated from the scallop in order to commercialize the scallop. Therefore, at present, the mantle and the midgut gland separated from the scallop are enormous and are discarded. Therefore, in order to use the mantle as a processed food, it is necessary to separate the midgut gland from the mantle separated from the scallop. Unless this can be achieved, it will not be a practical device.

SUMMARY OF THE INVENTION The present invention has been developed to solve the long-awaited problems in the industry, and an important object of the present invention is to provide a waste disposal method capable of efficiently separating a complex-shaped midgut gland. It is an object of the present invention to provide a method and an apparatus for removing a mid-gut gland, which effectively utilize the scallop mantle used for food. Another important object of the present invention is to make effective use of a discarded scallop shell for foodstuffs, which can be manufactured easily and at low cost and which can significantly increase the processing capacity per hour. An object of the present invention is to provide an intestinal gland removing method and apparatus.

[0008]

According to the first aspect of the present invention, there is provided a method for removing a midgut gland, which effectively utilizes a discarded scallop mantle for food. To this end, the midgut gland is separated from the mantle as follows. The scallop bark 9 with the midgut gland 3 attached to the mantle 2 is accelerated together with water to collide with the perforated plate 4.
It is very important to make the perforated plate 4 collide with water. The raw body 9 colliding with water on the perforated plate 4
The midgut gland 3 is separated by the shock of the collision. In the present invention, the shell of the scallop that collides with the perforated plate generally comprises the midgut gland from which the scallop has been removed and the mantle. However, it goes without saying that the raw material from which the scallop is not removed can be made to collide with the perforated plate.

The method for removing a midgut gland according to claim 2 of the present invention, which effectively utilizes the discarded scallop mantle for food, is intended to accelerate the peeling of the scallop against the perforated plate. Instead, the perforated plate 4 is moved so that the peeled body 9 collides with the perforated plate 4. The midgut gland 3 is separated by the shock of the collision.

Further, according to claim 3 of the present invention,
The mid-gut gland removing device that effectively uses the discarded scallop mantle for food is provided with a cylindrical porous plate 4, an accelerating fin 5 on the outer periphery, and a cylindrical perforated plate 4. And a driving means 7 for rotating the rotating shaft 6
And The bare body 9 supplied between the perforated plate 4 and the rotating shaft 6 and having the midgut gland 3 connected to the mantle 2 is accelerated by the rotating acceleration fins 5 and collides with the perforated plate 4, causing a shock of the collision. The gut 3 is separated.

Further, the apparatus for removing a mid-gut gland effectively utilizing a discarded scallop mantle for food as described in claim 4 of the present invention comprises a tubular casing 8 and a casing. The rotary shaft 6 is disposed inside the rotary shaft 8 and has a perforated plate 4 fixed to the outer periphery. The drive unit 7 rotates the rotary shaft 6. The device having this structure does not fix the perforated plate 4 but rotates the perforated plate 4 and causes the peeled body 9 to collide with the perforated plate 4. That is, the bare body 9 supplied between the casing 8 and the rotating shaft 6 and having the midgut gland 3 connected to the mantle 2 collides with the rotating perforated plate 4, and the midgut gland 3 is shocked by the collision. Separated.

[0012]

FIGS. 2 to 4 show a method and an apparatus for removing a midgut gland from a mantle according to the present invention, which effectively utilize a scallop mantle for food. These figures show a state in which the midgut gland 3 is removed from the mantle 2 from which the scallop 1 shown in FIG. 1 has been removed. However, according to the present invention, the midgut gland 3 can be separated from the raw body 9 from which the scallop is not separated. Mantle 2 relatively moved toward perforated plate 4 with water
Approaches the perforated plate 4 as shown in FIG. As shown in FIG. 3, in the mantle membrane 2 which vigorously collides with the porous plate 4 together with water, the midgut gland 3 is crushed by the shock of the collision. The water transferred together with the mantle 2 serves as a transport medium for transferring the mantle 2 toward the perforated plate 4, and crushes the midgut gland 3 more efficiently. Since the crushed midgut gland 3 becomes smaller,
As shown in FIG. 4, it is separated from the mantle membrane 2 through the perforated plate 4. The water flowing vigorously through the perforated plate 4 efficiently separates the crushed midgut glands 3 from the mantle 2. Further, water impinging on the perforated plate 4 together with the mantle 2 flows on the surface of the mantle 2 from which the midgut 3 has been removed, and cleans the mantle 2 neatly. The bare body 9 that cannot sufficiently separate the midgut gland 3 by one collision repeatedly collides the perforated plate 4 with water many times to separate the midgut gland 3.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. However, the following examples are given to illustrate the method and apparatus for removing the midgut gland that effectively uses the discarded scallop mantle for food to embody the technical concept of the present invention. In addition, the method and apparatus of the present invention do not specify the types, materials, structures, arrangements, processes, types of used raw materials, and the like of the components as follows. The method and apparatus for removing the midgut gland of the present invention, which effectively utilizes the discarded scallop mantle for food, can be modified without departing from the scope of the claims.

Further, in this specification, in order to make it easy to understand the claims, the numbers corresponding to the members shown in the embodiments will be referred to as "claims", "actions", and "actions". In the column of "Means for solving the problem". However, the members shown in the claims are
It is by no means specific to the members of the embodiment.

The apparatus shown in FIGS. 5 and 6 for effectively using the discarded scallop shell for food is a casing 8, a perforated plate 4 disposed in the casing, and a perforated plate. A rotating shaft 6 arranged to be rotatable inside 4
And a motor as driving means 7 for rotating the rotating shaft 6, and a solid substance pump 10 for supplying the mantle 2 to which the midgut 3 is attached to the casing 8.

The casing 8 is made of metal or plastic, has a cylindrical shape as a whole, and has a watertight structure in which both ends are closed. The casing does not necessarily need to be cylindrical, and may be, for example, a polygonal cylinder. The casing 8 shown in the figure has an inlet 11 at the left end, an outlet 12 at the right end, and a drain 13 at the outer periphery.

From the inlet 11, the mantle 2 to which the midgut gland 3 is attached is supplied together with water. The mantle membrane 2 supplied from the inflow port 11 is obtained by removing the scallop 1. However,
It is also possible to remove the mid-gut gland by supplying a bark that does not remove the scallop, that is, a bark in which the scallop, mantle, and midgut are attached.

From the outlet 12 of the casing 8, the mantle 2 from which the midgut 3 has been removed is discharged together with water. The water mixed with the gut 3 is drained from the drain 13.

The porous plate 4 is a metal mesh, a metal plate or a plastic plate provided with a large number of through holes. The perforated plate 4 has a cylindrical shape and is disposed inside the casing 8. The casing is partitioned into an acceleration chamber 14 in which the rotating shaft 6 is disposed and a separation chamber 15 into which water including the midgut gland 3 flows. doing. The drain port 13 of the casing 8 is connected to the separation chamber 15, and the outlet port 12 is connected to the acceleration chamber 14.

As shown in FIGS. 5 and 6, the cylindrical perforated plate 4 is designed to have an inner diameter approaching the tip of the acceleration fin 5 of the rotating shaft 6. Perforated plate 4 approaching the tip of acceleration fin 5
In addition, the water accelerated by the acceleration fins 5 and the bare body 9 vigorously collide with each other, so that the midgut gland 3 can be efficiently separated from the mantle membrane 2.

The holes of the perforated plate 4 cannot pass through the mantle membrane 2,
It is designed to have a size that can efficiently transmit water. Perforated plate 4
Is too large, the mantle 2 from which the midgut gland 3 has been removed passes. In addition, when the holes of the perforated plate 4 are enlarged, the damage to the mantle membrane 2 when the mantle membrane 2 collides vigorously is increased. This is because when colliding with the hole, the mantle membrane 2 is greatly deformed into a shape protruding into the hole. Mantle 2
If the pores of the perforated plate 4 are made too small in order to reduce the damage to the water, the water containing the crushed midgut gland 3 cannot be efficiently transmitted. That is, the pressure loss through which water permeates increases. The pores of the perforated plate 4 are preferably formed so that the mantle membrane 2 cannot pass therethrough, water containing the crushed midgut gland 3 can smoothly pass therethrough, and further, in order to reduce damage to the mantle membrane 2, for example, 0.5 to 10 mmφ, preferably 1 to 5 mmφ,
More preferably, it is designed to be 2 to 5 mmφ. Perforated plate 4
If the pores are small, the crushed midgut gland 3 may be clogged. Clogging can be effectively prevented by making the holes into slits. The width of the slit is, for example, 1 to
Designed to be 5 mm.

The water discharged from the discharge port 12 of the casing 8 contains the mantle 2 and the crushed midgut gland 3. In particular, if the amount of water used is reduced, the outlet 12
Many of the crushed midgut glands 3 are mixed in the water discharged from the water. The crushed midgut gland 3 mixed with the water discharged from the outlet 12 can be removed by separating the water from the mantle 2. Alternatively, the crushed midgut gland 3 attached to the mantle 2
Can be removed by washing the mantle 2.

The rotating shaft 6 is located at the center of the cylindrical perforated plate 4 and is arranged so as to be coaxial therewith via a bearing or the like. The rotating shaft 6 has a plurality of acceleration fins 5 fixed radially on the outer periphery. The acceleration fin 5 is fixed to the outer periphery of the rotating shaft 6 so as to extend in the radial direction. Although a metal plate can be used as the acceleration fin 5, it is preferable that the acceleration fin 5 be a flexible plastic plate or a rubber plate. This is to prevent the bare body 9 from being damaged by colliding with the acceleration fin 5. Furthermore, the corner of the peripheral edge of the acceleration fin is chamfered into a smooth curved surface. If there is a sharp corner, when the peeled body 9 collides here, it is damaged and the commercial value is reduced.

The acceleration fin 5 shown in the cross-sectional view of FIG. 6 has its tip curved backward with respect to the rotation direction. The acceleration fins 5 of this shape have features that the smooth body 9 can be accelerated more smoothly and damage can be reduced, and that the smooth body 9 can be efficiently accelerated in the radial direction and collide with the perforated plate 4 at a high speed. Further, the acceleration fin can be fixed at an angle to the central axis like a screw. The acceleration fin that is inclined with respect to the central axis has a feature that, when the rotation axis is rotated, water can be peeled off and accelerated in the transport direction of the body. For this reason, a device capable of accelerating water containing peeled meat by a rotating shaft has a feature that the midgut gland can be separated by transferring the peeled meat and water without necessarily using a solid matter pump.

The rotating shaft 6 penetrates the casing 8 in a watertight structure, is connected to a motor as driving means 7, and is rotated by the motor. The solid matter pump 10 has a suction side connected to the peeling tank 16 and a discharge side connected to the casing 8. The solid substance pump 10 sucks the peel 9 from the peel tank 16 using water as a transport medium, and supplies the water and the peel 9 to the casing 8. As the solid matter pump 10, any pump that can transfer solid matter without damage, for example, a solid matter pump having a bladeless impeller that rotates in a case can be used. The solid material pump having this structure has a structure similar to a sand pump, and is commercially available as a pump for transferring solid materials easily damaged, such as fish.

The method and apparatus for removing the midgut gland, which effectively utilizes the discarded scallop mantle for food as shown in these figures, separates the midgut gland 3 from the mantle 2 as follows. I do. A solid matter pump 10 supplies water and the peeled body 9 together from the peeled tank 16 to the acceleration chamber 14 of the casing 8 from the inflow port 11. The water and the bare body 9 supplied to the acceleration chamber 14 of the casing 8 are accelerated by the acceleration fins 5 of the rotating rotating shaft 6. The bare body 9 and water accelerated by the acceleration fins 5 are accelerated in the radial direction by centrifugal force and collide with the perforated plate 4 provided on the outer periphery of the rotating shaft 6. In the bare body 9 that has collided with the perforated plate 4, the midgut gland 3 is crushed by the impact shock, and is removed from the mantle membrane 2. The water accelerated in the radial direction together with the peeled body 9 presses the peeled body 9 against the perforated plate 4 to collide efficiently. The midgut gland 3 crushed by colliding with the perforated plate 4 passes through the perforated plate 4, is transferred from the acceleration chamber 14 to the separation chamber 15, and is discharged from the drain 13 to the outside of the casing 8. Some midgut glands 3 are mixed with water in the acceleration chamber 14 and discharged together with the mantle 2 from the outlet 12. The mantle 2 discharged from the outlet 12 is the one from which the midgut gland 3 has been removed, and is discharged together with water. After the mantle 2 has been washed and the midgut gland 3 has been completely removed, the mantle 2 is dried.

The apparatus shown in FIG. 5, which effectively uses the discarded scallop shell for food, transfers the peeled body 9 from left to right in the figure. Instead of the device for transferring the scallop shells in the horizontal direction, the device for effectively using the discarded scallop mantle of the present invention for food should be a device for transferring the scallop shells in the vertical direction. Can also. FIG. 7 shows an apparatus for separating the midgut gland from the mantle by transferring the bare body having the midgut gland attached to the mantle upward from the bottom. This device is also shown in FIGS.
In the same manner as in the apparatus described above, the peeled body 9 is accelerated together with water to collide with the perforated plate 4 to separate the midgut gland 3 from the mantle 2. The apparatus shown in FIG.
Is substantially the same as the method described for the apparatus shown in FIGS.

The apparatus shown in FIG. 7 has a structure in which the acceleration fin 5 is fixed to the rotation shaft 6 while being inclined with respect to the center axis like a screw, and the acceleration fin 5 of the rotating rotation shaft 6 is rotated.
Thus, the raw body 9 supplied from the tank 16 can be transferred from the lower part to the upper part of the casing 9 together with the water. The acceleration fins 5 inclined with respect to the central axis cause the bark 9 and water to collide with the perforated plate 4 by centrifugal force when the rotating shaft 6 rotates. Transfer upward. As described above, the device incorporating the rotating shaft that fixes the acceleration fin at an angle, such as a screw, can transfer the peeled body and the water upward without using the solid matter pump.

It has a vertical casing 8 shown in FIG.
The apparatus for removing the midgut gland of the scallop transfers water containing the peeled body 9 from the inflow port 11 opened at the lower end of the casing 8 toward the upper end. The inlet 11 is
Water is supplied to the inside of the perforated plate 4 provided inside the casing 8 and is supplied to the inside of the perforated plate 4 having a cylindrical shape. The perforated plate 4 has a large number of through holes. The bare body 9 supplied together with water into the acceleration chamber 14 provided inside the perforated plate 4 is accelerated by the acceleration fins 5 and collides with the perforated plate 4 to break the midgut gland 3. The water containing the crushed midgut gland 3 leaks out of the through-hole provided in the perforated plate 4 and is sent to the separation chamber 15. To drain water from the separation chamber 15, a drain 13 is opened at the lower end of the casing 8. Drain 13
By increasing the size of the perforated plate 4 and reducing the amount of passing water by reducing the size of the perforated plate 4, it is possible to prevent the water from collecting in the separation chamber 15.

The upper part of the vertical casing 8 has the midgut gland 3
Outlet 1 for discharging the separated envelope 2 to the outside
2 are provided. The discharge port 12 is opened at the upper end of the casing 8 and is connected to the acceleration chamber 14. The amount of water mixed into the mantle 2 discharged from here can be reduced. Water is supplied to the separation chamber 1 through through holes provided in the perforated plate 4.
5 to be drained from the drain 13. Therefore,
It is also possible to discharge only the mantle membrane 2 not containing water from the discharge port 12 and to convey it by a belt conveyor or the like. Also,
The mantle 2 can also be drained with a small amount of water. Further, the mantle membrane 2 can be discharged together with a large amount of water.
In the water discharged together with the mantle 2 from the outlet 12, crushed midgut glands 3 are mixed. The crushed midgut gland 3 mixed with water can be removed by separating the water from the mantle 2. Alternatively, the crushed midgut gland 3 attached to the mantle 2
Can be removed by washing the mantle 2.

The mid-gut gland removing apparatus shown in FIGS. 5, 6 and 7 separates the mid-gut gland by accelerating the peeled body and colliding with the perforated plate. Intestinal glands can also be isolated. The apparatus shown in FIGS. 8 and 9 shows a specific example in which a perforated plate is caused to collide with a perforated plate by rotating the perforated plate.

The devices shown in these figures are arranged inside a cylindrical casing 8 so that the rotary shaft 6 can rotate coaxially with the casing 8. The perforated plate 4 is fixed to the surface of the rotating shaft 6 instead of the acceleration fins 5. The casing 8 has a cylindrical shape, and is designed to have an inner diameter that allows the inner surface to approach the outer periphery of the perforated plate 4. At the left end of the casing 8 is an inflow port 11
, And a solid matter pump 10 is connected thereto, and a discharge port 12 is opened at the right end of the casing 8. In the apparatus having this structure, when the perforated plate 4 is inclined with respect to the center axis of the rotating shaft 6 and fixed like a screw, the rotating perforated plate 4 can accelerate and transfer the water and the peeled body 9. For this reason, even if the solid matter pump 10 is not used, the peeled meat is removed from the casing 8.
Can be transferred to

The device of this construction separates the midgut gland 3 from the mantle 2 as follows. A solid substance pump 10 supplies water and the solid body 9 together from the solid body tank 16 to the casing 8 from the inflow port 11. The water and the peeled body 9 supplied to the casing 8 collide with the perforated plate 4 of the rotating rotating shaft 6. In the bare body 9 that has collided with the perforated plate 4, the midgut gland 3 is crushed by the impact shock, and is removed from the mantle membrane 2. The midgut gland 3 crushed by colliding with the perforated plate 4 is mixed with water together with the mantle 2 and is discharged from the outlet 12 through the casing 8.
Is discharged to the outside. When the mantle membrane 2 discharged from the casing 8 is separated from water, the midgut glands 3 mixed in the water are separated. If necessary, the mantle 2 is washed to remove the midgut gland 3 neatly.

Further, the apparatus shown in FIGS. 10 and 11 is also an apparatus for rotating a perforated plate to collide a peeled body against the perforated plate. The devices shown in these figures are disposed inside a cylindrical casing 8 so that the rotating shaft 6 can rotate coaxially with the casing 8. On the surface of the rotating shaft 6, a perforated plate 4 having a closed structure which is closed but not closed is fixed. The perforated plate 4 having the closed structure is connected to the hollow portion 17 of the rotating shaft 6. The hollow portion 17 of the rotating shaft 6 is watertightly connected to the drain 13 via a rotary joint 18. The rotating shaft 6 is hollow and has a watertight structure.

The perforated plate 4 having a closed structure is radially fixed to the inner surface of the casing 8. These perforated plates 4 are connected to a separation chamber 15 provided on the outer periphery of the casing 8. The separation chamber 15 on the outer periphery of the casing is connected to the drain 13. Further, the rotating shaft 6 is connected to a motor as a driving means 7 via a gear.

The device of this construction separates the midgut gland 3 from the mantle 2 as follows. A solid substance pump 10 supplies water and the solid body 9 together from the solid body tank 16 to the casing 8 from the inflow port 11. The water and the peeled body 9 supplied to the casing 8 collide with the perforated plate 4 having a closed structure fixed to the rotating shaft 6 that is rotating. Further, the perforated plate 4 of the rotating shaft 6 accelerates the water and the peeled body 9 to collide with the perforated plate 4 fixed to the inner surface of the casing 8. In the bare body 9 that has collided with the perforated plate 4, the midgut gland 3 is crushed by the impact shock, and is removed from the mantle membrane 2. The midgut gland 3 crushed by colliding with the perforated plate 4 penetrates the perforated plate 4 and is transferred to the inside of the perforated plate 4 having a closed structure. The midgut gland 3 that has passed through the perforated plate 4 and flowed into the hollow portion 17 of the rotating shaft 6 passes through the rotary joint 18 together with water and is discharged to the outside. The midgut gland 3 that has passed through the perforated plate 4 fixed inside the casing 8 is discharged from the separation chamber 15 provided outside the casing 8 through the drain port 13 to the outside. The jacket 2 discharged together with the water from the outlet 12 of the casing 8 is separated from the water. Further, if necessary, the mantle membrane 2 is washed and the midgut gland 3 is completely removed, and then the mantle membrane 2 is dried. As described above, the mantle from which the midgut glands have been removed also removes the attached shells and soil.

[0037]

The method and apparatus for removing the mid-gut gland according to the present invention have an excellent feature that the mid-gut gland can be efficiently separated from the mantle having a complicated shape. This is because the present invention causes the scallop bark consisting of the mantle and the midgut gland to collide with the perforated plate together with water. In the case of bark that is hit against the perforated plate with water, the midgut gland is crushed by the shock of the collision. The present invention does not impinge the permeate and water on a perforated plate. The present invention is characterized in that water and a peeled body collide with a perforated plate through which water can permeate when collided. It is thought that the midgut gland can be separated even if the bark hits a board through which water cannot pass. However, if the bark and water collide with the board that cannot penetrate water, a water layer is formed between the bark and the board, and this water layer acts as a buffer, and the bark collides with the board surface efficiently. Can not. In the present invention, the bark strikes the perforated plate. The perforated plate allows water between the perforated plate and the perforated plate to permeate when the perforated plate collides. Therefore, according to the present invention, the peeled body can efficiently and directly hit the surface of the perforated plate violently, and the midgut gland can be effectively crushed by the impact of the collision and removed from the mantle. Further, the raw body that collides with the perforated plate does not collide with the perforated plate in an interview state.
Since the perforated plate has an infinite number of holes, the perforated body locally collides with the perforated plate without the hole portion contacting the perforated plate. That is, the collision area is reduced, and the impact at the collision portion is increased. This synergizes with the direct hit of the perforated plate with the perforated plate, so that a greater impact force is definitely applied to the perforated plate. For this reason, the present invention has the feature that the midgut gland can be crushed very efficiently and removed from the mantle.

[0038] Even more advantageously, the present invention allows the small intestine glands that collide with the perforated plate to be separated from the mantle by permeating the perforated plate. In addition, water that accelerates and permeates the perforated plate removes the mesenteric glands more efficiently in a state where the crushed mesenteric glands are washed away. Therefore, the present invention has an excellent feature that the midgut gland can be separated very efficiently.

Further, the present invention has a feature that the midgut gland can be efficiently separated with a very simple structure in which water and peeled body collide with the perforated plate. This realizes the feature that the equipment cost can be reduced and the processing capacity per time can be considerably increased. This is also very important for this type of device. This is because a huge amount of scallop mantle that has been discarded without being effectively used can be effectively used as food with an inexpensive device.
