Description

[Detailed Description of the Invention] In recent years, with the expansion of the scale of aquaculture and fishing, frozen frozen fish in the so-called slab shape has been increasingly used as feed. In order to use it, it is necessary to thaw it and shred or mince it depending on the purpose of use and the size of the feed fish, but the thawing method is usually done in the atmosphere. This work takes a long time, and there is a risk that feed fish that have been thawed due to atmospheric temperature may deteriorate or rot. This would lead to the death of the fish and contaminate the water quality of the entire farm, so in order to prevent this, the prior invention has been developed to provide (3) frozen frozen fish slabs in the required amount at the required time There is a crushing method and device for instantaneously crushing and crushing using mechanical force, and the present invention relates to an improvement thereof.
It is an object of the present invention to provide a highly advanced method and apparatus for making the cutting force and insertion bending stress on frozen frozen fish slabs even stronger, thereby reliably increasing the slab crushing force.

The present invention consists of three electric rotating rolls each having a large number of pyramidal or conical tooth pieces arranged and dotted on the outer circumferential surface, and two lower rolls having opposing parts movable relative to each other at a required interval. 1, the upper one is rotated inwardly relative to the lower two roll blocks, arranged in a triangular shape, and one or more roll blocks are arranged so that the upper one rotates in the same direction. between the lower two rolls.

Freezing frozen fish characterized by passing through a plate-shaped frozen frozen fish slab and crushing the solidified ice by cutting and penetrating bending stress with the rotating teeth (4) Special G8 1971-67173 (2) Fish Slab crushing method: A large number of pyramidal or conical tooth pieces are arranged and dotted on one outer peripheral surface, and three electric rotating rolls are arranged at the required intervals, and the lower two rolls are arranged with opposing parts. One roll block or a plurality of roll blocks are arranged in a triangular shape, with one upper roll block rotating in the same direction and two lower roll blocks mutually rotating inwardly. This is an apparatus for crushing frozen frozen fish slabs, which is characterized by the following.

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.

Three electric rotary rolls (2) (3)' (41) of the same diameter or different diameters each having a large number of pyramidal or conical tooth pieces (1) interspersed on the outer peripheral surface (41), one on the upper side. , the lower side has two pieces, and the plate-shaped frozen frozen fish slab S passes through and rotates with the tooth piece (1), and the slab S is cut or pierced and twisted by roll rotation, so that the slab 8 is crushed (5) At a required interval suitable for crushing, rotate the lower two rolls (2) and (3) in the same direction so that their opposing parts are free from each other. , the upper one roll (
4) are mutually inwardly rotated with respect to the lower two rolls (2) and (3), and arranged to face each other in a triangular shape, and the roll blocks are simply arranged in parallel or The entire structure is diagonal, and it is composed of one or more tortoises.◎
In addition, depending on the size of the slab S, the interval between each roll can be adjusted freely, and the interval between each roll (2) (3) (4
1, it is possible to arrange the rolls of different diameters as shown in FIGS. 4 to 6, and the design can also be changed to an upside-down triangular arrangement.

In the figure, % (7) and (8) are the slab feeding table mechanism at the entrance of the roll group.

The apparatus of the present invention is constructed as described above, and therefore, when the frozen frozen fish slab 8't-slab feeding table mechanism (7), (8) to (6) is continuously fed between the rolls of the group of rotating rolls, the slab is S becomes K when it passes from between each roll through the discharge guide plate (9) to the discharge port, but as the slab S passes between the rolls, three electric rotating rolls (2) (31 (41 times) Due to the movement, each of the rolls (2) (3) (41) is dotted with pyramidal or conical tooth pieces (1), and as a result, due to the rotation of the tooth pieces (1), The slab S is crushed or punctured to gradually break it into smaller pieces and then sent through rolls.

First, the roll arrangement is triangular, and the two lower core rolls (2) and (3) rotate in the same direction, with their opposing parts free-moving relative to each other. In contrast, the upper one roll is replaced by the lower two rolls (2
) (3), by mutually rotating inwardly, the sandwiching between the rolls while the slab is being crushed is first performed by the upper roll (4) and the lower near-side roll (3). ), the ice enters between the two rolls, and is firmly crushed or pierced by the opposing teeth (1) due to the inward rotation of the rolls (7), and the solidified ice is solidified. The crushed slabs are reliably and smoothly crushed by the upper roll (
4) and the inward rotating roll of the lower front roll (2), but on the way, when passing through the lower opposite roll + 2)j3) , the opposing rolls (2) 13) on the lower side rotate in the same direction, and as a result, the opposing portions are driven. That is, as shown by the arrow in the figure, the toothed piece (1) of one of the rolls (3) rotates downward, and the toothed piece (1) of the other roll (2) rotates upward, so that the roll ( 2) (3) When the slab fragments that have reached the interspace are pierced by the feeding teeth (1) of the rolls (2) and (3), it is more difficult than when the slab fragments are pierced by the inwardly rotating teeth. However, since the screw bending stress caused by the penetration is much stronger, the tearing force is extremely strong, and as a result, the crushing force caused by the free-floating teeth is much greater than the crushing force caused by the inwardly rotating teeth. The slab crushing becomes more powerful, and the solidified ice is crushed even more finely and instantly, and the frozen fish inside is also cut into fine pieces, demonstrating outstanding crushing performance. become.

The group of crushed slabs is then further crushed by the upper and lower rolls (2) and (4), which rotate inwardly, before being fed and discharged.

If necessary, the tooth piece (1) may be made to have a forward-inclined tooth type in the direction of rotation, so that the crushing action will be even better. In addition, by rotating each roll at different speeds, the chewing performance is improved, and the piercing with the floating teeth at one true speed is
As a result of the large penetrating torsional bending stress acting on the slab, the slab crushing force becomes extremely strong, and the crushing of the solidified ice and cutting of the contents of the slab S are carried out reliably and instantaneously.

As a result, the slab S is crushed into crushed ice chunks and crushed frozen fish, which are separated and discharged through the discharge (9) guide plate (9) section.

Note that depending on the thickness and size of the slab 8 and the freezing temperature,
Based on three triangular basic roll blocks,
As shown in FIG. 2, if the roll block is designed to have a plurality of continuous roll blocks, the number of moving crushing points increases, and as a result, smooth crushing of ice can be ensured for any slab. In addition, a design in which the roll arrangement and the entire chamber mechanism are arranged at an angle is suitable for passing through the slab. In addition, as the crushed slab passes above the interlocking rolls, some of the fine crushed ice blocks produced by the crushing action fall downward between the moving rolls, but the ice blocks are removed from the guide plate QQ. Ru.

As described above, the method and apparatus of the present invention are theoretically more advantageous in that the opposing teeth are driven by rotating in the same direction, compared to the prior invention which involves simple mutually rotating inwardly rotating rolls. Experiments have also shown that the crushing force for frozen frozen fish slabs is much stronger, and therefore, the slab S can be crushed automatically and reliably instantaneously using the mechanical force of a simple roll machine (10) mechanism. The method and apparatus of the present invention can be carried out efficiently, the crushing performance is significantly improved, and the adoption of the method and apparatus of the present invention can greatly contribute to the development of the fish aquaculture industry, making it very convenient and useful. .
