Description

{Crab Shells Removal Apparatus Having Improved Sorting Quality}

More specifically, the protrusion of the lower roller for removing the back skin is constituted by a first protrusion having a width smaller than the body width of the crab and a second protrusion having a width similar to the body width, The quickness of the skin removal is improved, the removal rate of the incisal projection of the crab is increased, and the sorting quality which can smoothly remove the back skin can be improved even when the sorting is not smooth at the entry of the crab.

It is known that there are 4,500 species in the world and 183 species in Korea. The crabs are divided into ten limbs among arthropods. The ten legs are functionally divided into a pair of claws and four pairs of walking legs. Crabs vary in their habitat and extrinsic characteristics as well as their species. Crabs have vegetation that crawl on the floor and process the carcasses of marine creatures that fall to the floor, which is also called the sea scavenger.

These crabs are one of the most important fishery resources of our country which is sea of three sides. They are steamed as they are, or boiled in boiling water, and then they are eaten by boiling the body or legs or by using soy sauce. And various types of frozen foods such as crab meat and various frozen foods have been processed and sold.

However, in order to process a crab into various kinds of processed foods, it is necessary to sort the crab different parts of the crab in a hard shell of the crab.

Fig. 1 and Fig. 2 are diagrams showing general crabs.

Referring to the drawings, a portion of a crab is composed of a trunk formed by a back shell 1 and a fold shell (not shown), a pair of legs 2, first to fourth legs 3, 4), and a tactile sense (5).

In order to separate such a crab, conventionally, a worker lifts a cutting knife and manually operates the legs 3 and the legs 2 to walk on the workbench by hand and the legs 2 Not only does it require a lot of labor by cutting and sorting, but also when a worker is injured by a shell of a crab (1), a shell of a crab or a knife in the process of manually cutting a shell of a crab using a knife There were frequent problems.

Accordingly, in order to improve inconvenience caused by manual work, a processing device capable of automatically processing crabs has been proposed in Korean Patent Laid-Open Publication No. 2015-0051461.

Fig. 3 and Fig. 4 are views showing the above machining apparatus.

Referring to the drawings, a conventional processing apparatus includes a transfer section A for continuously transferring a crab, a leg alignment section B for aligning the legs of the crab conveyed through the alignment means, (C) which cuts off the middle part of the body after removing the gills in the inside of the body by removing the gills at the same time, and a second cutter (C) (D) for cutting the divided both side edges of the ridges transported by the transporting means (A).

The first cut-off portion C is rotated by a motor and radially formed on the outer circumferential surface thereof to form a concavo-convex portion 15a. The convex portion 16a is rotated by a motor, And the back skin and the back skin of the crab body which are put between the back skin removing means 15 and the back skin removing means 16 are separated and discharged from the body at the same time .

At this time, on both sides of the guide 2 provided behind the back skin removing means 6, gill removing means 17 rotating in the direction opposite to the crazing direction by the motor are provided so that the gill removing means 7 is provided on both sides And a trunk cutting knife 18 driven by a motor is installed at the center in the rear of the gill removing means 7 to remove the gills from the first and second conveying belts 102 and 106 To cut the middle portion of the trunk of the red debris being transported by the transporting means.

6 to 10 protruding pieces 16a are radially formed on the outer circumferential surface of the center roll so that the back skin of the crab that enters the protruding piece 16a as it rotates is protruded from the protruding pieces 16a As shown in FIG.

In this process, the separation force is very high due to strong striking force between the back skin and the protruding pieces (16a), but there is a disadvantage that the back skin is not recyclable due to high breakage rate of the separated back skin, Problems arise.

In addition, when the position of the entering crab is not accurately aligned, the skin is not easily removed. As shown in FIG. 2, in the case of the inward projecting portion 7 such as a stutter or an undersurface, 15 or the back skin removing means 16 and remain on both side portions of the trunk so that it is inconvenient for a worker to manually remove it in the future.

Therefore, when removing the back skin (1), it is possible to minimize the distortion of the back skin and to minimize breakage of the back skin when the back skin is separated, and even when the entering crabs are not aligned smoothly, It is, of course, required to propose a machining apparatus in which the removal of the inward projecting portion 7 can be performed simultaneously with separation of the back shell 1 and the back shell 2.
