The present invention comprises a rectangular block, having a front face, a rear face, and two side faces. The front and rear faces have multiple pairs of aligned vertical slots, into which a knife can be inserted and moved up and down in a vertical cutting motion. The block is open at the top and openable at the bottom by means of a sliding or hinged trap door. In use, uncut chum is loaded into the block through the top opening, and the sliced chum accumulates within the block until the bottom door is opened, thereby depositing the sliced chum in a container beneath the block. The container serves to collect the chum and store it until it is used.

Methods and systems for processing fish, such as salmon, are provided which enable filleting of the fish in a particular efficient manner. An example method includes exposing a backbone of a fish from a belly side of the fish, positioning the backbone of the fish on a conveyor device, and conveying the fish with the backbone in contact with the conveyor device. The conveyor may be a spiked chain, and positioning the backbone of the fish on the conveyor device may include engaging the backbone of the fish with the spiked chain such that the fish straddles the spiked chain as the fish is transported. The method may further include cutting the fish from the dorsal side on each of opposing sides of a central plane of the fish to a location adjacent a connection of the pinbones of the fish with the vertebrae of the fish while the fish is conveyed with the backbone in contact with the conveyor device, and subsequently peeling the ribs and ventral spines from fillets of the fish.

A device for macerating bait, making chum, or both is provided. The device has a main housing having a top openable end and a closed bottom openable end; a removable lid attachable to the top openable end, wherein the removable lid comprises at least a fluid flow hole configured to, when placed in a fluid and towed behind the vessel, port the fluid to flow through the housing through bottom openable end and through the top openable end; a push rod disposed through the removable lid; a concentric cutting member attached to the push rod at a lower end of the push rod, wherein the concentric cutting member comprises a series of blades that are intersecting and have cutting edges on a top and bottom of the blades. A method of macerating bait is also provided.

A cutting apparatus for cutting a food object includes at least one cutting blade, an actuator arranged for moving the cutting blade before and during cutting, and an element comprising a receiving section arranged for receiving and abutting the cutting blade, and a supporting section arranged for supporting a food object before and during cutting. During cutting, the supporting section is arranged for being displaced, such as displaced by elastic deformation, by the cutting blade with respect to a position of the supporting section prior to cutting. During moving of the cutting blade, the cutting blade is arranged for displacing the supporting section subsequent to the cutting blade abutting the receiving section. The cutting blade and the element are arranged for being continuously in contact with each other.

This disclosure relates to apparatuses and methods for processing and grading food articles. For example, provided herein is a system for grading a portioned food article, in which the system includes: a first conveyor; a first receiving conveyor and a second receiving conveyor, defining a space therebetween; at least one spray-removal robot; and a third receiving conveyor. The spray-removal robot may include at least one valve with a nozzle, in which the valve ejects fluid through the nozzle to impact a food article being moved on the first conveyor toward the third receiving conveyor, such that at least one portion of the food article is moved by the impact through the space between the first receiving conveyor and the second receiving conveyor, and such that at least one portion of the food article is moved by the first receiving conveyor and the second receiving conveyor to the third receiving conveyor.

An arrangement for automatically removing a strip of dark meat from a fish fillet has a conveying unit for transporting the fish fillet from an inlet to an outlet area in a transport direction along a transport path. Starting from the inlet area, successively along the transport path, are provided: a first means for detecting dark meat; a first cutting apparatus for removing a middle partial strip of dark meat; a means for opening up the fillet such that cut surfaces of a ventral-side partial and of a dorsal-side partial strip of dark meat point upwards; a cutting unit for removing the partial strips, the cutting unit comprising second and third cutting apparatuses for removing the ventral and dorsal-side partial strips. A control device is connected to the detecting means and the cutting apparatuses, and all cuts are based on information from the detecting means. A corresponding method is provided.
