Abstract: A machine and method for mechanically cutting fish pieces includes a band knife for making cuts substantially parallel to a circumferential direction of a freezing drum. The first cutting device is adapted to be the first to come in contact with an uncut fillet and makes at least one cut directed in a thickness direction of the fillet laterally of the two main faces of the fillet and substantially parallel to a jacket face of a freezing drum. The first cutting device has at least one knife preferably providing self motion.

Abstract: The invention relates to longitudinal cutting of fish fillet pieces substantially parallel with the skin side (S) of the original fillet. This cutting in layers or slices takes place in that the fish fillet (F, F1) is brought into contact with a rotating cooled freezing drum (7, 7') which freezes the fillet (F2) at the skin side (S) and conveys it in retained position against the operative cutting edge of a driven, endless band knife (18). During the rotation of the drum (7, 7'), the operative cutting edge of the band knife (18) is displaced stepwise in relation to the drum circumference between two successive revolutions of the drum (7, 7'), in order to cut a fish meat slice (FS) successively for each drum revolution.

Abstract: The invention relates to a method and device for peeling food such as fish, complete or not, for example sardines, herrings, anchovies, etc.; fruits such as peaches or vegetables such as tomatoes whose skin has been previously subjected to a surface treatment. The method according to the invention is characterized in that the food products are displaced inside a conduit (54) wherein circulates an air flow generated by compression or depression. Application to the food industry.
