A method for ecological utilization of silver carp, including the pretreatment of silver carp and the process of making canned fish surimi. The fish meat of silver carp is processed canned surimi. The fish heads and bones are heated and undergo enzymatic hydrolysis by enzymes, and the residues of the filtration are prepared for fish bone powder. A filtration membrane is used to reduce the volume of the filtrate to 50% of fish surimi and then the filtrate is frozen to ice. The frozen part can be added to fish surimi. The transparent part from membrane filtration was used to produce protein powder or ingredients for beverages. Fish offal can be used to produce protein liquid fertilizer. Fish scales and skins can be used to produce collagen. The method adopts ecological utilization, which makes the silver carp meat used effectively, including its processed wastes. The method is a closed cycle process such that that no pollutants or wastes are discharged during the process.

Filleting apparatus for cutting fish fillets from flank bones. The fish fillets been processed by a ventral knife assembly and a dorsal knife assembly. A conveying apparatus, transporting fish tail-first in transport direction, having an endlessly circulating transport conveyor with at least one transport saddle receiving/securing a fish, a flank knife assembly with two flank knife units, opposing each other on both sides of the transport conveyor in the region of a transport saddle guide. Each flank knife unit has a rotatably drivable circular knife and counter-surface arrangement Circular knife is arranged at a distance from the counter-surface arrangement to form a cutting gap and a control device moves flank knife units relative to the transport conveyor from standby position into working position and back. The counter-surface arrangements vary the size of the cutting gap controllably during the processing operation.

The disclosure provides fish products and methods of making fish products, including mixing pieces of frozen fish and salt, and extruding the mixture of fish and salt into a fish product, wherein the fish product includes only the salt as an additive.

A cutting machine comprising one or more form tubes that are divided in two in the longitudinal direction into a front form tube section and a rear form tube sectionat least across a portion of its circumference, so that the two form sections can be moved from a pressing position in which they are aligned with each other into a loading position in which they are not aligned with each other, and in the loading position the rear form tube section can be loaded with a new meat strand while the rest of the previous meat strand is still being cut into slices and moved in the front form tube section. The blade may be disposed to simultaneously cut slices from a plurality of form tubes and may be disposed for motion in the longitudinal direction as well as a direction transverse to the longitudinal direction.

A cutting machine for cutting up pre-compressed meat strands into slices and a method for slicing pre-compressed meat strands, wherein the blade is moved forward in the feed direction to a limited extent after the blade has completely cut off a slice, and is either subsequently or simultaneously moved backward in the transversal direction. In this way, the forward movement of the meat strand to cut off the next slice can be started earlier.

A method and apparatus for filleting fish to produce high yielding fillets from relatively short bodied fish in the size range of about 600 grams to about 3.5 kilograms dependent on species. The method and apparatus are designed to be capable of handling salmon, tilapia, trout, arctic char, barramundi, snappers, walleye pike, striped bass and similar species where the rib follows the contour of the belly cavity. Further, the method and apparatus incorporate belly opening and eviscerating components prior to subjecting the fish to a backbone removal system so that the fish need only be headed, but not gutted, before introduction into the machine.
