AI Technical Summary

Technical Problem

Existing apparatuses for automatically recovering meat from headed and gutted fish are limited in their ability to adjust the distance between circular knives, leading to high yield losses and damage to the bone structure due to fixed orientations, particularly when processing fish with varying sizes and anatomies, resulting in inefficient and inaccurate meat recovery.

Method used

A control device adjusts the gap width between circular knives based on the detected fish anatomy, allowing for dynamic adjustment during the meat detachment process, ensuring precise cuts and maximizing yield by adapting to the specific anatomy of each fish.

Benefits of technology

The solution enables efficient and high-yield meat recovery with minimal damage to the bone structure, reducing waste and increasing the quality of the end product by optimizing the gap width according to the fish's dimensions and anatomy.

Abstract

The present invention relates to an apparatus (10) for automatically recovering meat (20) from headed and gutted fish (11), comprising a transport device (12) for transporting the fish (11) along a transport path (13) in transport direction T; a measuring device (14) for detecting the anatomy of the fish (11); and a detaching device (13) for detaching the meat (20) from the bone structure (18), the detaching device (13) comprising at least two rotatingly driven and controllably moveable circular knives (16, 17) which are spaced apart from each other to form a gap S, said apparatus being characterised in that the detaching device (13) comprises a control device (19), which is set up to adjust the width of the gap S depending on the fish anatomy detected by the measuring device (14), the control device (19) being configured to preset the width of the gap S before the meat (20) is detached from the bone structure (18) and to vary the width of the gap S while the meat (20) is being detached from the bone structure (18). The invention also relates to a corresponding method. In conjunction with Fig. 1
