BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for keeping fish and shellfish such as live octopus fresh.

[0002]

2. Description of the Related Art When a large amount of fresh fish and shellfish such as octopus, squid, and shellfish are sold, as a facility for treating freshness and longevity, water, salt water, or an aqueous solution containing a chemical solution is conventionally used as a wooden facility. It was placed in a barrel, placed on a suitable rotating seat and rotated, and thawed, salted, or treated with a chemical solution to prevent oxidation.

[0003]

[Problems to be Solved by the Invention] In such a conventional method for treating fresh food by a barrel, fresh fish and shellfish and a treatment liquid are put into a wooden barrel for each treatment work such as thawing, salted rice, or chemical treatment to seal the barrel. , This was rotated to stir the contents.

For this reason, it is necessary to open and close the barrel each time the treatment liquid is different, and there is a problem that such work is extremely troublesome and the work efficiency is poor. Further, when the barrel is rotated, the barrel is manually supported on the turntable to rotate the barrel, so that the barrel is not rotated sufficiently, and thus the flow of the treatment liquid is not sufficient.

This invention was made in consideration of the problems of the above-mentioned conventional method of treating freshness and preservation by a wooden barrel, and a drum and a treatment liquid barrel are combined to put fish and shellfish in the drum. An object of the present invention is to provide a processing device that can efficiently perform various processing operations without taking it out.

[0006]

In order to solve the above-mentioned problems, the present invention comprises a combination of a hollow cylindrical drum whose both ends are closed, and a processing liquid tank which receives this drum, the cylindrical drum communicating internally with its outer surface. The processing liquid tank is provided with a large number of small holes, a lid plate for putting in and out of fish and shellfish, and a hanging metal fitting, and the processing liquid tank has a supporting roller that rotatably supports the drum in the tank body and a driving unit that rotationally drives the drum. And the rotation shaft of the drive unit is connected to the drum by a detachable connection unit to form a fish and shellfish processing device.

[0007]

The processing apparatus according to the present invention constructed as described above is used for the processing of fresh and preserved fish and shellfish. For example, when thawing a frozen octopus, first, the cover plate of the removed cylindrical drum is opened and the frozen octopus block is put into the drum. The lid plate is closed and the drum is lifted and placed in the processing liquid tank.

Water for thawing is preliminarily poured into the treatment liquid tank, and the drum put therein is rotatably supported by the supporting rollers in the tank, and the rotary shaft of the driving unit is rotated relative to the drum. Are connected via a detachable connecting part. When the drum is rotated by the drive unit, the frozen octopus is agitated by the water that has entered the drum and gradually thawed.

When the thawing is completed, the drum is pulled up from the processing liquid tank, but at this time, the water that has entered the drum is discharged from the small holes of the drum and drained. When the first treatment is completed in this way, only the cylindrical drum is moved to the next treatment liquid tank.

The processing operation is performed by performing the same operation for each different processing.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing the overall construction of an embodiment of a processing apparatus for freshening and preserving fish and shellfish according to the present invention. This processing apparatus comprises a hollow cylindrical drum 1 and a processing liquid tank 2 for receiving the same.

In the cylindrical drum 1, both ends of the drum main body 3 are closed by side plates 4, and flanged rings 5 are provided at both ends thereof, and a large number of small holes 6 communicating with the inside are formed on the outer peripheral surface of the drum main body 3. It is provided at intervals. Further, the cylindrical drum 1 is provided with a lid plate 7 for taking in and out fish and shellfish at an appropriate position on the outer peripheral surface of the drum body 3. The lid plate 7 is fixed to the drum body 3 with a locking tool 8. Further, lifting hardware 9 for lifting the cylindrical drum 1 is provided at both ends of the drum body 3.

Although the drum body 3 is made of plastic in this embodiment, metal or wood may be used.
Although the small holes 6 are provided only on the outer peripheral surface of the drum,
It may also be provided.

Further, as shown in the cross section of FIG. 2, on the inner peripheral surface of the drum body 3, ridges 10 for stirring fish and shellfish inside are provided at appropriate intervals along the length direction. ing.

The processing liquid tank 2 has a tank body having a sufficient space for receiving the cylindrical drum 1 supported by a supporting portion 11, and a supporting roller 12 for rotatably supporting the cylindrical drum 1 therein. The support rollers 12 are provided on the bottom of the tank main body so as to support both ends of the drum main body 3.

A motor 13 for rotatably driving the cylindrical drum 1 is provided on the outer side of the processing liquid tank 2, and its rotating shaft 1
4 extends through the side wall inside the processing liquid tank 2. This rotary shaft has an L-shaped portion 15 at its shaft end as shown in FIG.
Is fixed, and the cylindrical drum 1 corresponds to this L-shaped portion.
The side end of is provided with a C-shaped receiving metal fitting 16, and these form a detachable connecting portion. Reference numeral 17 is a supply pipe for supplying the processing liquid into the bath.

The processing apparatus of the embodiment constructed as above is used as follows.

When treating fish and shellfish, such as octopus, thawing, salted rice, and chemical treatment are generally performed. This is to improve the freshness and preservation of frozen octopus before it is put on the market. Therefore, one cylindrical drum 1 and three processing liquid tanks 2 are prepared.

Outside the processing liquid tank, the cylindrical drum 1 is loaded with an appropriate amount of the block X in which the lid plate 7 is opened and the octopus is solidified with ice.
The lid plate 7 is closed and the drum 1 is lifted by a hook F of a hoisting device (not shown in FIG. 1).
Put it in. An appropriate amount of water as the processing liquid W is previously injected into the tank.

When the cylindrical drum 1 is placed in the tank, the L-shaped portion 15 at the tip of the rotary shaft 14 is adjusted upward so that it can be easily connected to the receiving bracket 16 on the drum side. The lower part of both ends of the drum is a support roller 12 that supports the drum at four points
Set correctly for.

When the motor 13 is driven to rotate in this state,
The cylindrical drum 1 rotates, the frozen octopus block X collides with the protrusion 10 in the drum, and the position is lifted and dropped, so that the drum is agitated. When the drum is put into the tank, water enters through the small holes 6 provided on the outer peripheral surface of the drum, so that the block X is thawed by the water together with the stirring action.

When the thawing is completed, the cylindrical drum 1 is again lifted from the tank by the lifting device and moved to the next processing liquid tank. At this time, the cover plate 7 of the drum may remain closed.
Water is discharged through a large number of small holes 6 in the drum.

In the next processing tank, salt water is supplied as the processing liquid W into the tank. When the cylindrical drum 1 is put into this tank in the same manner as the above procedure, salt water penetrates into the drum and the salt is burned as the drum rotates.

When salt chaff is completed, it is further sent to the next chemical treatment tank. In this tank, an aqueous solution containing an antioxidant is supplied in order to prevent oxidation of the octopus in the middle of the distribution route until it is shipped to the market and improve the preservation state. The treatment in this tank is performed in the same procedure as before,
When this process is completed, the cylindrical drum 1 is lifted from the tank, the lid 7 of the drum is opened, and the processed octopus is taken out and shipped to the market.
