Description
DK 2022 70025 A1 1
The invention concern a devein processing machine for deveining animals or part of animals belonging to the group of decapods such as shrimps, prawns and crayfish tails. The invention further concerns a feeding unit configured for feeding such animals or part of animals to a devein processing machine for deveining the animal or part of the animal.
With some conventional shrimp deveining systems, the shrimp is first transported to a cutting unit where the shrimp is split to expose the vein, and then afterwards the shrimp is transported to a deveining unit for removing the vein. The vein may be removed by use of a device e.g. a brush that serves to dislodge the shrimp vein from the shrimp.
Further, with some conventional shrimp peeling systems or shrimp deveining systems, there is a need for an operator to manually load and orient the shrimps in a specific direction on a feeding tray. If a shrimp is turning the ‘wrong way’, it will not be positioned in the correct position when it passes the cutting unit, which means that the shrimp may be cut improperly with the result that the shrimp may need to be discarded.
The invention has the purpose of providing an alternative method for removing the vein from animals or part of animals belonging to the group of decapods such as shrimps, prawns and crayfish tails in a simple and more controlled manner to eliminate disadvantages, which sometimes occur in conventional deveining machines.
This is achieved by the a devein processing machine for deveining animals or part of animals belonging to the group of decapods such as shrimps, prawns and crayfish tails according to the present invention, the machine comprising:

The engagement elements are configured for grapping and pulling the vein out from the animal or part of the animal.
Figure 9 shows one embodiment of details of the disc 109 to be positioned on opposite sides of the circular knife (not shown here) and in figure 10 is shown the number of engagement elements 119, here shown as notches, which are positioned at the side of the discs facing the circular knife and are configured for removing the vein. Also seen in figure 10 is a small part of the common driven shaft 111. As seen in this figure the circular knife may be configured for oscillating. That is, when the circular knife is rotated by the common driven shaft 111, it may be oscillating or vibrating according to the plan running perpendicular to the common driven shaft. In figure 10 is shown that the movement/variation may be 2 degrees, but it could be between 0.5 to 5 degrees according to the plan running perpendicular to the common driven shaft.
Figure 11 shows one embodiment of the feeding unit comprising a positioning sensor system 123 (here shown as sensor 1 and sensor 2) configured for assuring that the animal or part of the animal 125 is positioned correctly before being feed to the conveying means of a devein processing machine or a peeling machine. In the situation where the animal or part of the animal should be transported to a devein processing machine, the animal or part of the animal should be positioned with the head-end first to be positioned correctly, which can be seen in this figure, meaning that it will be the head-end that first comes into contact with the deveining unit after being transported by the conveying means. In this situation, the positioning sensor system, shown here as two sensors; ‘sensor 1’ and ‘sensor 2’ will sense the shrimp at the conveyer belt at more or less the same time — that is the two sensors will detect the movement of an object (shrimp) at the same point in time, which indicate that the shrimp is positioned correctly. The positioning sensor system can then convert these movements into signals suitable for processing, transmission, or control. The positioning sensors in the positioning sensor system can be any suitable sensor known by a skilled person. In one or more embodiments, the
DK 2022 70025 A1 13 positioning sensors are laser sensors or fiber optic sensors. The positioning sensor system may indicate that an adjustment of the position of the animal or part of the animal e.g. a shrimp on the conveying means is required in order to assure that the shrimp will be properly positioned.

In the situation where the animal or part of the animal should be transported to a devein processing machine the animal or part of the animal should be positioned with the head-end first to be positioned correctly, which is nor the case here in figure 12. In this figure, the shrimp is positioned wrongly with the back-end first. In this situation, ‘sensor 1’ will sense the shrimp at the conveyer belt before ‘sensor 2' — that is the two sensors will detect the movement of an object (shrimp) at two different time points, which indicate that the shrimp is positioned in a wrong direction. The positioning sensor system can then convert these movements into signals suitable for processing, transmission, or control. When the positioning sensor system has indicated that the animal or part of the animal is not positioned correctly, a control system can be configures to assure that the animal or part of the animal is sorted away at the end of the feeding unit before the animal or part of the animal will be feed to conveying means of a devein processing machine or a peeling machine.
