Description

[Detailed Description of the Invention] Traditionally, fish of various sizes have been used as feed for fish farming, and as the scale of fish farming has increased, not only live fish but also frozen fish have recently been used for a stable supply. It is increasingly being used. In order to make the frozen fish convenient for transportation and storage, the feed fish is frozen together with water, and the frozen fish is frozen into a slab-like block of ice. To use this for feeding, the ice must be thawed and shredded or minced depending on the purpose of use and the size of the feed fish. Put the fish into a tank and fill it with water, line up the frozen fish on a concrete floor, sprinkle water on them, or use the sea surface to attach a net to the raft frame.
Methods such as putting frozen fish into the tank and thawing it with seawater have been adopted. however,
In this method, the ice-melting work is usually carried out in the atmosphere, which takes a long time, and the outer part of the slab is exposed to atmospheric temperature for a long time after the ice has melted. The subsequent processing takes a long time, and the thawed feed fish tends to change or rot, which often causes the death of farmed fish or contamination of the farm. In order to prevent this, there has been a need for a technical means that can instantly thaw the required amount of feed frozen fish slabs as needed and maintain a low temperature to prevent deterioration.

The present invention solves this problem by directly mechanically crushing the solidified ice of frozen fish slabs without performing any preliminary treatment such as deicing, and maintains the temperature at a low temperature even with the crushed water. The purpose is to prevent the obstacles and damage that inevitably occur to the fish farming industry using conventional methods by feeding it to farmed fish, and to contribute to the development and improvement of the industry.

Accordingly, the present invention provides two guide passages in which a plurality of pyramidal or conical tooth pieces are arranged and dotted on the outer circumferential surface of the machine body, which is formed by opening a guide passage provided with an inlet and an outlet. Or, by arranging more electric rotating rolls facing each other at required intervals so as to rotate inwardly at different speeds, between the different speed rotating rolls,
A method for crushing frozen frozen fish slabs, which is characterized by passing through a plate-shaped frozen frozen fish slab and crushing the solidified ice by cutting and penetrating bending stress with pyramidal or conical teeth rotating at different speeds. as a specified invention,
In addition, two or more electric motors having a large number of pyramidal or conical tooth pieces arranged and dotted on the outer circumferential surface of the machine body are formed by opening a guide passageway with an inlet and an outlet. The rotating rolls are rotated at different speeds at a required interval suitable for passing the plate-shaped frozen frozen fish slabs and crushing the solid ice by the cutting and penetrating bending stress caused by the teeth. A related invention is a crushing device for frozen frozen fish slabs, which is characterized in that they are arranged facing each other so as to rotate inward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The crushing method and apparatus according to the present invention will be described below with reference to the embodiments of the accompanying drawings of the crushing apparatus in which the crushing method is carried out.

The passage 3 of the fuselage body 4 is formed by opening a guide passage 3 with an input port 1 at the upper part and an outlet 2 at the lower part.
A large number of pyramidal or conical protrusion tooth pieces 5 are arranged and dotted on the outer circumferential surface of each intermediate portion of the 2.
In this or more illustrations, a plate-shaped frozen frozen fish slab S passes through three electric rotary rolls 6, 7, and 8 of different diameters, and the mutual teeth 5 are rotated inwardly to form the slab. The intervals can be freely adjusted by intervening an appropriate interval adjustment mechanism to the required interval suitable for the size of the slab S, which is suitable for cutting the slab S or breaking the solidified ice by twisting due to rotation at different speeds related to the piercing. and the rotating shafts 6', 7', of each of the rolls 6, 7, 8.
Pulleys 9, 10, 11 of different diameters are attached to 8',
A motor M is installed at the bottom of the machine body 4, and a belt is stretched from the motor shaft to each pulley 9, 10, 11, and the rolls 6, 7, 8 are arranged so as to rotate inwardly at different speeds. It is equipped and configured.

The means for rotating the electric rotating rolls 6, 7, and 8 at different speeds is not only due to the difference in the roll diameter and the difference in the pulley diameter as described above, but also due to the difference in the pulley diameter even if the roll diameter is the same. It is possible to adopt any suitable construction means, such as making the diameters different or intervening a suitable transmission mechanism, and such means are completely arbitrary.

Further, the spacing adjustment mechanism for the rolls 6, 7, and 8 can also be formed using any suitable configuration means. For example, in the illustration, one roll 7 is set at a fixed position,
The other rolls 6 and 8 are provided with guide long grooves 12 and 13 in their shaft bearing parts, respectively, and the rotating shafts 6' and 8' are slidably inserted thereinto, and appropriate shaft bearings are fitted to the rotating shafts 6' and 8'. A configuration is adopted in which washers 14 and 15 are attached, and operating handle screw rods 16 and 17 are screwed into screw grooves provided thereon. Then, the threaded rod 16,1
7, the bearing washers 14 and 15 move, and accordingly, the rotating shafts 6' and 8' slide in the long grooves 12 and 13, and the rolls 6 and 8 move from the roll 7 in the fixed position. The spacing is adjusted by moving far and near relative to the handle, but any other suitable spacing adjustment mechanism can be designed based on handle operation, and is completely arbitrary.
The number of rolls 6, 7, and 8 to be arranged is based on two facing each other, but depending on the size of the slab S and the progress of crushing due to the freezing temperature, an appropriate number of three or more rolls may be arranged. Become.

It should be noted that if a small cart is attached to the body 4, it will be convenient to transport the body, and the machine can be connected to the mincing mechanism.

Since the apparatus of the present invention is constructed as described above, the interval between the electric rotating rolls 6, 7, and 8 can be adjusted to correspond to the size of the frozen frozen fish slab S by operating the interval adjustment mechanism, so that the slab S can be adjusted between the rolls. When the slab S is continuously thrown into the guide passage 3 from the input port 1 at the upper part of the machine body 4 at the required intervals,
The slab S passes through the discharge port 2 between the rolls. Therefore, when each of the rolls 6, 7, and 8 is rotated by a motor, they rotate inwardly relative to each other.
Then, since each of the rolls 6, 7, and 8 has pyramidal or conical teeth 5 arranged in a protruding manner on its outer peripheral surface, the teeth 5 mutually rotate inward as the rolls rotate. As a result, the slab S is crushed or pierced by the inwardly rotating teeth 5 and passed between the rolls.

Thereby, the slab S has pyramidal or conical teeth 5 due to mutual inward rotation on the opposing rolls.
Definitely crushed or pierced by
Not only will the solidified ice be crushed smoothly, but the frozen fish inside will also be cut into pieces.

If necessary, the tooth piece 5 may be formed into a tooth type that is inclined forward in the direction of rotation, to further improve the crushing action.

By rotating the inward rotations of the rolls 6, 7, and 8 at different speeds, the chewing performance is good, and the piercing by the opposing teeth rotating at different speeds causes torsional bending stress on the slab. As a result, the crushing force becomes stronger and more reliable due to the twisting force, so that the crushing of the solidified ice and the cutting of the contents of the slab S can be carried out reliably and instantaneously. Thereby, the slab S is discharged from the passage 3 to the discharge port 2 in a state where it is separated into crushed ice chunks and crushed frozen fish chunks.

Depending on the thickness, size, and freezing temperature of the slab S, if crushing with two rolls as shown in Figure 3 is insufficient, use three or more rolls as shown in Figure 4. This arrangement ensures satisfactory crushing.

As described above, if the method and apparatus of the present invention are used, the long-time thawing work of the frozen frozen fish slab S as in the past can be completely eliminated, and the slab S can be moved into the aircraft using the mechanical power of a simple mechanism. 4 input port 1
The slab S can be automatically and reliably instantaneously separated into crushed ice chunks and crushed frozen fish by just a simple operation of inputting the ice cubes, and the ice melting efficiency can be significantly shortened.
The crushed frozen fish mass can be immediately used for feed or minced meat processing, and as a result, it can greatly contribute to the development of the fish aquaculture industry, which is very convenient and useful.The device of the present invention has a simple mechanism. It has many advantages, such as being inexpensive and mass-producible, being very economical and in high demand, and being convenient because it can be connected to a mincing device.
