Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a fish meat refiner for removing bones, scales, and other foreign substances other than fish meat from fish meat slurry.

After the alkaline bleaching, the fish meat slurry is sent to a process to remove foreign substances such as small bones and scales.This process is the last step in removing foreign substances, and is an important operation to obtain high-quality minced fish meat.

Conventionally, a horizontally arranged cylindrical porous tube was used as a device to remove solid foreign matter such as small bones, skin, and shells mixed in fish meat slurry made by adding water to shredded fish meat. It is known that a rotary shaft provided with a blade is provided at the center and the rotary shaft can be rotated by a drive device. In this conventional sushi refiner, when the blades are rotated by a drive device and the fish meat slurry is fed into the perforated cylinder, only the slurry in the fish meat slurry passes through the small holes in the perforated cylinder due to the action of the blades. Although it is designed to separate impenetrable foreign substances such as small bones, it has the disadvantage that it cannot be operated continuously for more than 1 to 2 hours because the solids separated from the slurry gradually accumulate in the porous cylinder. .

In the present invention, the shape of the perforated tube is formed into a truncated conical shape whose diameter decreases as it approaches the foreign matter discharge port from the fish meat slurry supply point, and the blade is placed from the supply port of the porous tube to the foreign matter discharge port. By tilting it so that it recedes in the direction opposite to the direction of rotation of the rotating shaft as it approaches, the above-mentioned drawbacks of the conventional method have been removed. The aim is to provide 7 ainers.

The present invention will be explained in detail below with reference to the drawings.

The accompanying drawings show one embodiment of the present invention, and numeral 1 in the drawings represents a base. A pair of left and right bearing members 2.3 are provided on the base 1, and support the rotating shaft 4 horizontally and rotatably in the circumferential direction via ball bearings 5.6.

The rotating shaft 4 has a fixed shaft 7 rotatably supported in the circumferential direction by a ball bearing 6 on the member 3, and one end (the right end in FIGS. 1 and 2) 8a is inserted into the insertion hole of the fixed shaft 7. 7a via a sliding key 9 so as to be movable in the axial direction, and the other end 8b
The bearing consists of a movable shaft 8 which is pivotally supported by the member 2 via a ball bearing 5 and a bearing case 10, and the bearing is connected to a fish meat supply cylinder 11 provided inside the member 3 and to this supply cylinder 11. A truncated cone-shaped porous tube 12 that communicates with a large diameter supply port 12a and a foreign matter discharge tube 13 that communicates with a small diameter foreign matter discharge port 12b of this porous tube 12.
The movable shaft 8 is passed through the center of the shaft. In the above bearing case 10, the bearing has a screw hole 2aK provided in the member 2.
The bearing is fastened to the member 2 by a lock nut 14.

Inside the supply cylinder 11, there is a two-threaded screw 1.
5 is fixedly attached to the movable shaft 8, and the fish meat slurry put into the supply cylinder 11 is fed into the porous cylinder 12 from the nozzle 16. Inside the broken porous tube 12, there are 6
A number of blades 17 are firmly attached to the movable shaft 8 at intervals of 120 degrees.

This blade 17Fi is rotated clockwise in FIG. 4 by the rotating shaft 4 to splash the fish meat slurry onto the inner circumferential surface of the porous tube 12, forming a diameter of 1.5 mm in the porous tube 12.
It is pushed out through countless small holes 18a of the multi-hole tube 12, and is inclined at an angle θ so that as it approaches the outlet 12b from the supply port 12a of the multi-hole cylinder 12, it recedes in the direction opposite to the rotational direction of the rotary shaft 4. Then add the fish meat slurry to 1 piece.
7, in the downstream direction (direction of the discharge port 12b) inclined by θ degrees with respect to the orthogonal line of the pick rotation axis 4, and
Only foreign matter sent to the discharge port 12b without exiting from the small hole 18a is removed from the discharge port 121) through the discharge tube 1.
The structure is such that the water is discharged to the If the inclination angle θ of the blade 17 is too large or the taper angle α of the perforated cylinder 12 is
If the inclination angle θ is made too small, not only the foreign matter but also the surimi will be discharged from the outlet 12b, and conversely, if the inclination angle θ is made too small and the Shita bar angle α is made too small,
Foreign matter gradually accumulates inside the porous cylinder 12. Further, when the inclination angle θ is increased and the taper angle α is also increased, the fish meat slurry is subjected to a strong force, so that even foreign substances such as small bones come out together with the surimi from the small holes 18a formed in the porous cylinder 12. Therefore, the size of the perforated tube 12 and the blades 17 are determined by the rotational circumferential speed of the blade 17 and the taper angle α of the perforated tube 12.
Determined by taking into account the following.

The above θ is set to 1° to 1[P preferably 4° to 6°, and α is set to 1° to 20°, preferably 1° to 2°.
°, can.

Here, to explain the structure of the perforated cylinder 12, this perforated cylinder 1
2 is a metal semi-cylindrical plate 18 with countless small holes 18a, which is reinforced with a frame 19. Two half-cylindrical bodies 20 are inserted into assembly holes 19a formed in the frame 19.
A is inserted into a truncated conical shape, and one end is attached to the mounting seat 11a provided on the supply tube 11, and the other end is attached to the attachment seat 13a provided on the foreign matter discharge tube 13. mounted, further mounting seat 11a,
It is placed and held on a support metal fitting 24 fixed to the lower part of 13a. Note that the support fitting 24 supports the lower half cylinder 20 so as to be rotatable in the circumferential direction.

A water nozzle 25 is disposed inside and above the hopper 23, and a continuously variable speed drive device 27 is connected to the end of the rotating shaft 4, that is, the fixed shaft 7 via a coupling 26. . A hopper 23 is supported by legs 22 at the center of the base 1, and a removably provided cover 28 is provided on the top of the hopper 23.

Next, the operation of the surimi refiner of the present invention configured as described above will be explained.

First, the drive device 27 is activated to rotate the screw 15 and the blades 17 together with the rotary shaft 4 (movable shaft 8). In this case, the rotation of the drive device 27 is transmitted to the movable shaft 8 via the coupling 26 , the fixed shaft 7 and the sliding key 9 .

In the above operating state, fish meat slurry is continuously fed into the supply tube 11 from the nozzle 16. The fish meat slurry introduced into the supply cylinder 11 is immediately fed into the perforated cylinder 1-2 by the screw 15, and is transferred to the perforated cylinder 1 by the action of the blades 17.
The fish meat slurry becomes homogeneous (
become microscopic).

The fish meat becomes soft due to the above action, and the small hole 1 of the plate 18
The material passing through 8a is taken out to the hopper 23. In addition, solid foreign matter such as small bones and scales that cannot pass through the small holes 18a gradually moves downstream due to the inclination of the blades 17, and
b is discharged into the discharge tube 13. The fish meat pressed against the inner circumferential surface of the porous cylinder 12 by the action of the blades 17 is removed from the discharge port 12b.
Since the inner circumferential surface of the porous tube 12, which is tapered toward the feed hole 12a, receives an appropriate force in the direction of the feed hole 12a, the water does not pass through the inside of the porous tube without passing through, so that the feed rate and dewatering effect are enhanced.

In the above, if the gap between the tip of the blade 17 and the inner circumferential surface of the porous tube 12 is large, the small hole 18a will be easily held and the fish meat will not be discharged from the discharge port 12b. Loosen the bearing case 10.
, and move the bearing case 10, movable shaft 8, and blade 17 together to the left in FIG. 1 to reduce the above gap.

In addition, if frictional heat is generated by the rotation of the blades 17 and affects the product, water is spouted from the water nozzle 25 to prevent the temperature from rising. The water vigorously jetted from the water spray nozzle 25 prevents the small holes 18a from being clogged.

When cleaning or replacing the porous cylinder 12, open the cover 28 of the hopper 23, loosen the bolts 21a and 21b and remove the upper half cylinder 20, and then support the lower half cylinder 20. Remove it by rotating it half a turn upward along the metal fitting 24.

In the above embodiment, the movable shaft 8 is inserted into the insertion hole 7 of the fixed shaft 7.
Although the fixed shaft 7 and the movable shaft 8 are attached to the shaft 7a via a sliding key 9, the fixed shaft 7 and the movable shaft 8 may be attached by using a spline mechanism so as to be movable in the axial direction. The perforated cylinder 12 may be made movable in the axial direction with respect to the blade 17.

As explained above, in the refiner for ground blue according to the present invention, the blades that directly work to separate foreign substances retreat in the direction opposite to the rotational direction of the rotary shaft as they approach the discharge port from the supply port of the porous tube. Since the cylinder is tilted at an angle so that the foreign matter is gradually moved to the discharge port, foreign matter does not accumulate in the porous cylinder, and therefore work can be continued for a long time. In addition, the porous tube is formed in a truncated cone shape so as to become thinner toward the discharge port, and a force is applied to suitably move the fish meat and foreign matter pressed against the inner peripheral surface by the blades toward the supply port. Therefore, it has the effect of increasing the dehydration effect and product release.
