DEVICE FOR FILLETING FISH Russian patent published in 2017 - IPC A22C25/16 

FIELD: food industry.

SUBSTANCE: device includes a feeding conveyor, side conveyor belts, cutting elements mounted on both sides of the spinal bone of the fish carcass, a feeding gear support for the spinal bone of the fish carcass. The cutting elements are represented by closed belt knives, each belt knife being mounted on two pulleys and equipped with a drive. The width of the belt knife blade is oriented parallel to the direction of feeding the fish carcass, and the knife sharpening plane is oriented at an angle to the feeding direction and is located on the side of the knife blade, facing the spinal bone of the fish carcass. Each belt knife is provided with a spring-loaded tensioning roller interacting with the knife blade, providing a predetermined amount of elastic deformation to adjust the cutting line in the plane perpendicular to the feeding direction. The drive rollers for the side conveyor belts are made in the form of cones oriented with the base upwards. Additional driven cone rollers, made spring-loaded, are used. The device is provided with a support device for the fish carcass, the upper part of the housing of which is made with a longitudinal groove for the feeding gear support for the spinal bone of the fish. The gear support is made in the form of a closed flexible gear element mounted on two pulleys located in the housing of the support device for the fish carcass. Oppositely arranged vertical grooves for the belt knives are made on both sides of the longitudinal groove on the housing.

EFFECT: invention allows to reduce the meat loss of fillets, to improve the cut surface quality.
