Description

[Detailed Description of the Invention] The present invention relates to a crustacean dehulling device for dehulling the shells of krill, small shrimp, etc.

In recent years, krill has attracted attention as a promising protein resource.

This krill must be disposed of within a short time after being caught.
Because the oxidative and proteolytic enzymes are extremely strong, the action of these enzymes causes the flesh to turn black and mushy, rapidly decreasing its freshness.

Therefore, when producing shelled krill, a device that can shell a large amount of krill in a short period of time is required.

As conventional threshing devices of this type, the following ones have been proposed.

1 As shown in Japanese Patent Application Laid-Open No. 53-54596, a rotating disk and a roller rotatably disposed on the rotating disk with a minute gap allow the krill supplied to the central part to move between the rollers and the rotating disk. It is wedged between the disc and the shell is peeled off.

2 As shown in Utility Model Application No. 53-60100.

A screw shaft is arranged on a line adjacent to a pair of rollers that are arranged with a small gap and continuously rotate half a rotation in opposite directions, and while the krill is transported by the screw shaft and water, the krill is bitten between the pair of rollers. It is like peeling off the shell.

However, with the device 1) above, it is structurally impossible to make the dehulling part multi-shelled, and it is not suitable for mass processing, while the device 2) above is capable of multi-stage configuration and is suitable for mass processing. However, water nozzles are required for each stage, a drain plate and a device to move the drain plate up and down are required, and the rollers, screw shafts, and drain plate are installed at an angle, so it is difficult to install inside the ship. If the ceiling height is limited, such as in Japan, it is possible to have only 4 or 5 levels at most.

Furthermore, the structure becomes very complicated because a large amount of water is required for watering, and it is necessary to drive the rollers, screw shafts, and draining plates, and it is also necessary to install watering nozzles at each stage. There were many problems.

The present invention was proposed in view of the above-mentioned points, and consists of a conveyor placed horizontally and a rotor placed diagonally from the upstream side to the downstream side in the conveyor transport direction with a small gap above the conveyor. a partition plate disposed substantially parallel to the roller with a small gap between the rollers on the downstream side of the roller in the direction of conveyance; A crustacean feeding device is provided on the conveyor on the upstream side as a feeding site; a shell storage device provided on the same side as the shell storage device, and a shell storage device provided on the upstream side of the partition plate in the conveyor transport direction and close to the end of the conveyor. Features and Features The purpose is to provide a crustacean shelling device that is efficient, capable of mass processing, and simple in construction.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

Reference numeral 7 denotes a conveyor drive motor, which transmits power to the drive shaft 6 of the lowermost conveyor via a sprocket 8, chain 9, and sprocket 10, and sequentially connects the drive shaft hess brocket 11 of the upper conveyor to the drive shaft 6 of the lowermost conveyor. chain 1
2. Power is transmitted through the sprocket 13 to drive each conveyor in the same direction and at the same speed.

The rollers 14 are rollers disposed diagonally from the upstream side to the downstream side in the conveyor transport direction, and are arranged in multiple rows in parallel on the conveyor 2 of each stage with a suitable gap between them.

A shaft 15 of the roller 14 is rotatably supported by the frame 1.

Reference numeral 16 denotes a roller drive motor, which transmits power to the shaft 15 of the leftmost roller in each stage via a sprocket 17, a chain 18, a sprocket 19, etc., and sequentially transmits power to the shaft of the rightmost roller. Power is transmitted through gears 20, 21 and 22 to rotate each roller in the same direction and at the same speed.

Reference numeral 23 denotes a partition plate disposed downstream of each roller 14 in the direction of conveyor transport with a small gap between the conveyor 2 and substantially parallel to each roller, and 24 stands on the upstream end side of each roller 14 in the direction of conveyor transport. A crustacean supply section 24 is provided on the upstream side in the conveyor transport direction, and one end of a supply hose of a crustacean supply device described below is opened in the supply section 24 .

Figures 4 to 6 show an example of a crustacean feeding device, in which 25 is a conveyor that supplies crustaceans from a storage (not shown), and 26 is a partition plate that sorts the crustaceans that are fed on the conveyor 25. , 27 is a supply box provided at the bottom of the board, which has a rectangular hole 28 at the bottom and wheels 29 at the side, and is equipped with a motor 30, a sprocket 31, and a chain 3.
2. Crankshaft 3 driven via sprocket 33
4 via a crank pin 35 and a connecting rod 36, and is configured to reciprocate along a guide rail 37 in the direction of the arrow in the figure.

Reference numeral 39 is a separation box provided at the lower part of the supply box 27 for separating and supplying the crustaceans to each actor row, and has a large number of holes 39 at the bottom.

Reference numeral 40 denotes a number of crustacean supply hoses connected to the holes 39 of the separation box 38, and the other ends thereof are opened to the crustacean supply section 24 for each row of actors as described above.

Numeral 41 is a shucked meat storage chute disposed on the anti-crustacean supply section 24 side of each roller 14, and is connected to the gutter 42 to store shucked meat.

43 is on the same side as the shelled meat storage chute 41, and the partition plate 23
It is connected to the gutter 44 by a shell storage chute arranged on the side of the shell, and the shells are stored therein.

Next, the dehulling effect of the above device will be explained using krill as an example.

The krill is placed on the krill supply conveyor 25 from the krill top layer, sorted by a board 26, and dropped into the supply box 27.

Since the supply box 27 is reciprocated along the guide rail 37 by the above-described crank mechanism, the separation box 3 is removed from the hole 28.
The krill in row A in the separation box 38 is supplied to the krill supply section 24 in row A' in each stage via the krill supply hose 40.

Similarly, B +B', C+C', D +D', E→
E', F-F', GG', H+H',
I + I' and J → J' are respectively supplied.

Here, the roller 14 is installed obliquely to the belt conveyor 2, the belt conveyor 2 is driven in the direction of the arrow, and the roller 14 is rotated in the direction of the arrow, as shown in FIG. Thus, the supplied krill 50 is subjected to a pulling force M of the belt conveyor 2 and a pulling force N to the roller 14. Eventually, a force in the direction of φ acts on the krill itself, and a force is applied between the belt conveyor 2 and the roller 14. It is bitten, and the pressure at this time crushes it and removes the shell.

Since there is a small gap between the belt conveyor 2 and the roller 14, the peeled shell 52 passes through the gap, while the peeled meat 5
is mainly caused by the roller axial component Mx of the pulling force M of the belt conveyor 2.
4, falls into the shell chute 41, and is stored in the shell gutter 42.

Further, the shells 52 fall along the partition plate 23 into the shell chute 43 together with the water used to supply the krill, and are stored in the shell gutter 44.

Therefore, the water used during shelling is only the water used when feeding krill, and the amount is small, and it is simply the belt conveyor 2 and roller 1.
Since it is a combination of 4, the structure is simple and the gap per stage can be narrowed, so even when used in a narrow place such as inside a ship, it can be multi-staged and the throughput can be increased.

Furthermore, if the whiskers or legs of krill get stuck in the gap between the partition plate 23 and the belt conveyor 2, the belt conveyor 2 is temporarily stopped and reversed, and the krill supply hose 40
The krill supply section 24 can be easily cleaned by sprinkling water on it.

Depending on usage conditions, the roller 14 may be tapered to have a larger diameter on the krill supply side to increase the circumferential speed of the roller during rotation to improve the krill biting force.
On the discharge side, the diameter can be made small and the circumferential speed can be slowed down so that the shell does not get caught in the shelled meat.

Even in this case, the gap between the rollers and the belt conveyor must be equal at any position on the belt conveyor.

As is clear from the embodiments described above, according to the present invention, it is possible to obtain a threshing device that can efficiently dehull grains, can process a large amount of grains, and has an extremely simple structure.
