Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a fish meat blood collecting device used in the fisheries industry. More specifically, it relates to a device that scrapes only the blood joints from a fish body that has been cut into two or four parts.

In the fisheries industry, many devices, including Utility Model Publication No. 1973-8000, have been researched and developed to automatically remove blood from fish meat. However, all of these tools used steel knives to scrape the chiai, so even if various measures were taken to match the shape of the chiai, the shape and depth of the chiai would vary. Because each item is different, some have blood marks left on them,
It takes time to remove this unscraped material, and in some cases, the fleshy part is scraped off, significantly reducing yields. The current situation is that it has not yet been put into practical use.

The present invention was developed in consideration of this current situation, and uses a chip that performs the scraping action without bending when the resistance is low, but bends and ceases to perform the scraping action when the resistance becomes large. The purpose of this invention is to provide a device that completely scrapes off the blood joints but does not scrape off the fleshy parts.

Next, an example of implementation of the apparatus related to the present invention will be explained based on the drawings.

In Figure 1 of the drawings, reference numeral 1 denotes a belt made of a flexible material such as rubber or plastic, on the outside of which a number of pieces 2 of the same material are protruded at predetermined intervals. As shown in Figure 2, when it hits the meat part a of the fish body 3, it bends backwards and does not perform the scraping action, but as shown in Figures 3 and 4, when it hits the blood joint part b, it does not bend. The thickness is such that it has a cutting effect. However,
As shown in FIGS. 1 and 6, this belt 1 is stretched between stationary left and right rollers 4 and 5 and upper and lower rollers 7 and 8 that are moved up and down by a swing frame 6. The belt 1 is caused to run in a fixed direction by rotating the rollers 4 or 5 at an arbitrary speed using a variable speed motor 9. Reference numeral 10 denotes a cam fitted into the above-mentioned swing frame 6, which is fixed to a shaft 11 and rotated at an arbitrary speed by a variable speed motor 12 linked to the shaft 11, so that the shape of the cam 10 can be used to adjust the joint part b.
The cutting piece 2 is made to make a shallow cut into the fish body 3 at a shallow place, and when the blood meeting part b becomes deeper, the cut is made deeper accordingly, and when it becomes shallower, the swinging frame 6 is operated so that the cut becomes shallower. It is.

It should be noted that the width of each belt 1 described above can be made as narrow as possible, and the more belts are arranged in parallel, the more accurately the belt 1 can be adapted to the frontal shape of the chiai shown in FIG. 5 of the drawings. As shown in Fig. 7, a large number of belts 1 are installed together, and each belt 1 is rotated in conjunction with each other, and the support frame 6 is operated in conjunction with the cam 10, so that various parts of the joint part a are sectioned by a large number of chips 2. For convenience, the number of belts 1 in FIG. 7 is halved from that shown in FIG. 5. Reference numeral 13 denotes a conveyor for transporting fish bodies 3, which stores the fish bodies 3 in a holding body 14 as shown in FIG.

In the apparatus configured as described above, the belt 1
The belt 1 is made of urethane rubber with a hardness of 80, and on the outside thereof there are provided a number of pieces 2 made of the same material to a thickness that does not bend when the resistance is small but bends when the resistance becomes large. As shown in the figure, support means 4, 5, 6, 7, and 8 are arranged in parallel according to the width of the fish body 3 as shown in Figure 7, and held under the belt 1. When the fish body 3 supported by the body 14 is sent by the transfer conveyor 13, when the fish body 3 reaches the bottom of the belt 1, the pieces 2 provided on the belt 1 hit the fish body 3, and the fibrous and strong meat is removed. In the case of part a, since the resistance is large, the cutting piece 2 bends backward as shown in FIG. 2 and does not perform the cutting action. However, in the case of the flesh part b, which is brittle and easily powdered, the cutting blade 2 performs the cutting action without bending, as shown in FIGS. 3 and 4, so the meat part a
The blood removal is performed reliably by escaping the flesh part a and shaving off only the blood part b.
Even according to the frontal shape as shown in the figure, the chip 2 bends in the shallow part of the blood meeting part b, but does not bend in the deep part, so that it takes a shape that matches the front shape of the blood meeting part b.
The blood and flesh b of the fish body 3 is scraped cleanly, but the flesh part a is hardly scraped off, and the scraped blood and flesh part b gradually moves to the outside as the fragments 2 move. It is discharged and does not remain in the fish body 3.

The device for removing blood from fish meat according to the present invention has a flexible belt attached with a large number of pieces to remove the meat part of the fish body due to its flexibility and to scrape off the blood part.
By pressing the shavings against the part of the fish body where there is blood and rotating it, it is possible to scrape off only the part where there is blood without scraping the flesh, so there is no need for manual finishing and the yield of meat is good. Since the blood collection is performed automatically and efficiently, and there is no swarf buildup, a unique effect is achieved in economical promotion of complete blood collection.
