Description

one

Devices for removing meat from segments of crab limbs are known, consisting of a transporting device, a disc knife for notching an armor and a puller, made in the form of a pipe, which passes at one end into a needle. In addition, a transport device is known, consisting of a horizontal conveyor and two lateral conveyors located above it, which form a wedge-shaped gap between them.

In the proposed device, for the purpose of mechanized feeding of crab limbs and minimizing waste of meat, a transport device consisting of one horizontal and two lateral conveyors located above it, a disc knife with a stop for incision of the segment of the segment and a puller for separating the notched shell are used. from m sa The two side conveyors are connected to each other and form a wedge-shaped gap.

The puller for separating the incised armor can be made in the form of a wedge-shaped plate, which passes at the end into the needle. To transport segments of any size, the side conveyors can be interconnected by toothed sectors. Moving separated from the shells of ma

It can be produced by jets of fluid supplied from the nozzles mounted above the puller. FIG. 1 shows a diagram of the proposed device; in fig. 2 shows a second arrangement of the knife.

The device consists of a horizontal conveyor 1, two lateral conveyors 2 located above the horizontal;

a disk knife 3, a stripper, made in the form of a wedge-shaped plate 4, which passes into the needle 5, for separating the notched shell and nozzles 6 for supplying water. Conveyors 2 are interconnected by gear.

sectors 7. To limit the notch, limiter 8 is used.

The proposed device works as follows.

Separate segments of crab legs are served

on the conveyor 1 and with the help of the lateral conveyors 2 are advanced under the disk knife 3, which cuts the shell in the longitudinal direction to a depth set by the stop 8.

Then the transporting device advances the segment further and stringing it onto the needle 5, which enters the section from the segment and slides on the underside of the shell. Gradually the needle 5 puller goes into

an expanding wedge, the lateral edges of which are first separated from the underside of the shell, and then the shell is deployed as the wedge expands. The armor goes down under the puller, and the m from the segment remains on its surface. The removal of a piece of meat from the surface of the puller is performed by subjecting it to jets of water supplied from the nozzles 6.

The disk knife 3 may be located horizontally (see Fig. 2). In this case, the upper side of the carapace is cut along the entire segment.

Subject invention

Claims (4)

1. A device for extracting meat from joints of crab limbs, characterized in that, for the purpose of mechanized feeding of joints and minimizing waste of meat, it jointly used a transport device consisting of a horizontal conveyor and two lateral conveyors above it connected between them with the formation of a wedge-shaped gap, and a circular knife with a stop for incision of the armor of the segment and a puller for separating the notched armor from the mass, located above the horizontal conveyor. 2. The device according to claim 1, characterized in that the puller is made in the form of a wedge-shaped plate, which passes into the needle at the end. 3. The device according to claim 1, characterized in that, for the purpose of reliable transportation of segments of any size, the lateral conveyors are interconnected by the toothed sectors. 4. A device according to claim 2, characterized in that, in order to move the car separated from the shell, nozzles for supplying jets of liquid are installed above the stripper.
