Embodiment Construction

[0035] The fish used for processing were in the form of decapitated, slaughtered and hollowed out, peritoneal fish bodies 1, as seen in Figures 1A and 1B. This is the body of a fish of the tilapia species, which is mainly characterized by a relatively sturdy main bone 110, also commonly referred to as a dorsal bone, of which, especially in Figure 1C, can be seen from the illustration of the skeleton or skeleton 11, The dorsal spines 113 project upwards from the main bone over the entire length of the fish, the ventral spines 114 project downwards in the area in front of the caudal fin 15 and arch around the abdominal cavity in the area of ​​the abdominal cavity 120, also projecting from the dorsal bone 110 Side or rib spines 111 extend. At the end of the abdominal cavity, extending from the dorsal bone 110 to the anus, fish of the tilapia species have a relatively dense and rigid anal spine 112 that extends to the origin of the pelvic fins 14. The pelvic fin is also, like the...

Abstract

When fillet killed and headless fish broodstock, the abdominal cavity of which is opened up, especially the species tilapia, dorsal and ventral cuts are made up to the backbone and cleanly cut separating cuts are made in the remaining area attached to the backbone, while the fillets are peeled from the ribs. The aim of the invention is to enable machines to be used for such fish, rendering extensive manual treatment superfluous. Before the fillets are peeled from the ribs, the ventral folds are trimmed by a machine to remove parts which reduce the quality of the fillet, while the peeling cuts are made with two degrees of freedom in order to adapt to the particularly stiff rib profile.

Description

technical field [0001] The present invention relates to a slicing method for decapitated, slaughtered and eviscerated fish, in particular in the bulk processing of reared fish, in particular tilapia, in which the fish fillets in the dorsal region by means of a The dorsal incision that exposes the dorsal spine and on the ventral side on the one hand in the caudal region by means of a ventral incision that leads to the spine and exposes the abdominal spine and a severing cut that connects the dorsal incision and the ventral incision, on the other hand The segmentation is separated from the skeleton by means of scraping or peeling, and the segmentation is carried out from the spine along the ribs surrounding the abdominal cavity with a concessional counter-pressure. In addition, the present invention relates to a corresponding (fish) filleting device, comprising a back knife for exposing the dorsal spine until the spine is exposed; an abdominal knife for exposing the ventral spin...
