Device and method for skinning fish fillets

Abstract

An apparatus for skinning fish fillets includes a skinning knife to separate skin from the fish fillets, a delivery element to deliver the fish fillets into the region of the skinning knife, a driver roller for the skin separated from the fish fillets, a contact pressure element including a device to indicate a position of the contact pressure element, a discharge element to carry away the skinned fish fillets; and an element arranged in a region of the driver roller to monitor an input of fish fillets onto the driver roller and an output of fish fillets from the driver roller.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a National Stage Application of PCT / EP2008 / 006504, filed Jul. 30, 2008, which designates the United States and claims the priority of German patent application DE 10 2007 038 365.9, filed on Aug. 11, 2007, the subject matter of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] The invention concerns an apparatus for skinning fish fillets, comprising a delivery element for delivering the fish fillets into the region of a skinning knife, the skinning knife for separating the skin from the fish fillet, a driver roller for the skin separated from the fish fillet, a contact pressure element having a means for controlling the position of the contact pressure element, and a discharge element for carrying away the skinned fish fillets. Furthermore, the invention concerns a method for skinning fish fillets, comprising the steps of: delivering a product stream composed of fish fillets on a delivery e...

AI Technical Summary

Benefits of technology

This solution ensures a uniform and continuous product stream, prevents accumulation of contaminants, and allows for automatic error correction, maintaining a reliable processing flow and preventing blockages.

Problems solved by technology

However, with these apparatuses and methods there is the drawback that the fish fillets which are provided with bone or fin remains or other contaminants can catch on the skinning knife in practice.

The result is then an accumulation of products at the skinning knife, which hinders processing, namely the skinning of subsequent fish fillets.

This leads to faulty processing of the fish fillets, so that the skinned fish fillets are of only poor quality.

There may also be a complete blockage in the region of the gap between driver roller and skinning knife, which leads to stopping of the product stream.

The signal triggered by the contact pressure element is, however, not sufficient on its own to distinguish between a fault and a long fish fillet.

To put it another way, the fact that the contact pressure element is deflected for longer than planned on the one hand could mean that there is a fault, and on the other hand could indicate that a particularly long product is being skinned.
