Abstract

The invention relates to the fishing industry and can be used in skinning fish fillets. The purpose of the invention is the expansion of technological capabilities, improving the quality of skinning, improving the reliability of the device and reducing the loss of meat during skinning. According to the invention, after the fish fillet is fed longitudinally, the skin is captured by squeezing the fillet with a flexible element while pressing the skin to the support, then the skin is bent along the grip line and the fillet is separated from the skin between the skin and fillet. In the device for carrying out the method, a disk 2 rotated by a shaft 3 drives the conveyor 1 and the flexible element 4. The fillet is pulled into the wedge between the conveyor 1 and the flexible element 4, which presses the fillet and presses against the end of the disk 2. The fillet is pulled between the disk knives 6, then removable tools are inserted into the gap between the skin and the catfish and the fillets are finally separated from the skin. 2 hp ff, 3 ill.

Description

The invention relates to the processing industry of the fishing industry and can be used for skinning fish fillets.

The purpose of the invention is the expansion of technological capabilities, improving the quality of skinning, improving the reliability of the device and reducing the loss of meat during skinning.

An example of the method.

The essence of the method of skinning fish fillets lies in the fact that fish fillets are served longitudinally down and head cut forward and pushed with a flexible element along the axis of symmetry to the skin with simultaneous cutting at the place of pressing. The skin is bent and fixed on a support, the removable tools are inserted between the skin and meat on either side of the pressing point and the fillets are separated from the skin,

Thus, the process of skinning is carried out in two stages: 1st — separation of the fillet into two parts along the axis of symmetry and pressing of the skin to the support; 2nd - separation of msa from the skin. In the process of separating the meat from the skin, the latter is pressed against the support along the entire line of symmetry. Therefore, even if the skin is damaged in several places, it will be firmly held by the flexible member. This is also true in the case when there are bone growths in separate places on the skin of the fish. And since the removable elements do not have cutting edges, these elements only separate the meat from the skin, but do not damage it. The proposed method allows skinning of fish with mechanical damage: gusts of skin, abrasions, scuffing, etc. and also with fish fillet, on the skin of which there are bone growths.

For carrying out the method, a skinning device for fish fillets is used.

Fig. 1 schematically shows a device for skinning fish fillets, side view; figure 2 is the same, top view; on fig.Z - phased separation of the skins from the fillets.

The device comprises a two-belt feeding conveyor 1, a disk 2 kinematically associated with it, rigidly mounted on the shaft 3 and having a groove along its periphery. The working part of the disk 2 through a system of pulleys freely rotating on SBO axes is covered by an endless flexible element 4. On the side surfaces of the pulley 5 disk knives 6 are rigidly fixed. To the side surfaces of the disk 2 are tight

Removable tools 7, located directly behind the disk blades 6, fit. The flexible element 4 is tensioned by the pulley 8 using the tensioner 9. The endless flexible element 4 should be made in the form of a string.

The device works as follows.

The disk 2 driven by the shaft 3 drives the conveyor 1 and the flexible element 4. The fish fillet is fed with the skin 1 down and head cut forward. Since flexible element 4

located at an acute angle to the conveyor 1, the fish is drawn into the wedge formed by the plane of the conveyor 1 and the flexible element 4. The fish is pressed from the flexible element 4 to the skin and pressed against the end face of the disk 2. The fish fillet is pulled between the circular knives 6, while the bending of the skin takes place along the grip line to the side surfaces of the disc 2 with simultaneous delamination of the fillet from the skin

at the interface of knives 6 with disc 2.

Then, the removable elements 7 are inserted.

in the gap between the skin and the catfish and happens

final separation of the fillet from the skin.

The cartridge is placed in the receiving tray or some container (not shown), and the skin is retracted.

The proposed fish skinning device is highly efficient and reliable in handling.

different types of fish.
