A separation and singulation system for presenting shrimps or other product individually to a processor. The separation and singulation system includes a divider pan that separates a layer of shrimp into several lanes, a shaker pan that receives the lanes of shrimp and agitates them to separate clumps of shrimp and a flume for providing further singulation and acceleration of the shrimp. The singulated, separated shrimps are then sent to a processor.

A crab eviscerating disc is used in a crab processing machine and a method for processing a crab to a market condition. The disc is used to mill a groove along the underside of a crab body without completely cutting the crab body. Each tooth on that disc has a cut clearance angle of zero degree, and a hook angle of zero degree. Because of these teeth, the depth of the groove is limited by a bony plate and a bony ridge in the crab body. The visceral cavities of the crab body are cleaned by high pressure water sprays oriented in the groove while the crab body is still attached.

A novel method for automated extraction of crawfish tail meat comprises placing cooked crawfish on a tray having a bottom slot, applying a downward pressure to the cooked crawfish, extending a rotating brush through the bottom slot to urge the cooked crawfish into a horizontally exposed position, extending a rotating blade through the bottom slot to an incision, then applying a vacuum force to the bottom slot simultaneous to an increase in the downward pressure, causing the cooked crawfish to bulge and the tail meat to be extracted through the slot, after which the carcass is ejected. A plurality of trays can either be rotated in a circular path or conveyed along a linear path above the various tools as cooked crawfish are loaded and carcasses are ejected.

A machine for pre-treatment of selected shrimp types that are to be forwarded to machine peeling, which machine, across a conveyor belt with shrimps and at a height above this, comprises one or more mounted rotating brush that is driven by a motor and which in interaction with the distance to the conveyor belt separates the heads of the shrimps from the body.

An apparatus for fixing and transporting crabs during slaughter has a rotationally driven conveying element guided about deflection and/or drive elements to form an upper and lower run, and at least one holding apparatus for fixing the crabs. Each holding apparatus is attached to the conveying element for transporting the fixed crabs in a transport plane along a transport path in a transport direction from a loading station to at least one processing station. Each holding apparatus has a supporting plate for receiving a crab and at least two holding means arranged transversely to the transport direction at a distance from each other. The holding means are pivotable relative to the supporting plate about an axis A.sub.H, lying substantially in or parallel to the transport plane and directed transversely to the transport direction, from a receiving position into a clamping position and back. A corresponding method is also provided.

Shrimp processing apparatus to peel shrimp along with methods for peeling shrimp are described herein. The shrimp processing apparatus may be provided in systems including one or more processing stations configured to peel individual shrimp, where peeling may involve removal of shell segments on the dorsal surfaces of the shrimp abdomen and/or removal of pleopods/swimmerets on the ventral surfaces of the shrimp abdomen and, optionally, separation of shell segments. The processing systems and methods may, in one or more embodiments, include apparatus for and methods of measuring the shrimp.

Shrimp processing apparatus to head and optionally sever the mud veins of shrimp, along with methods for heading and mud vein severing are described herein. The shrimp processing apparatus may be provided in systems may include one or more processing stations configured to perform one or more of the following functions on each shrimp: measurement of individual shrimp, severing the mud vein of individual shrimp, and heading of individual shrimp.

A distribution device automates and meters distribution of feed in a commercial shrimp production facility utilizing a stacked shallow tank configuration. The device includes an elongated support surface positioned over and extending along an elongated tank having an open top. A shuttle moves along the support surface to move along a length of the tank. A hopper to hold feed is coupled to the shuttle. A spreader is in environmental communication with the hopper to distribute feed from the hopper and a meter is operationally coupled between the hopper and the spreader for controlling an amount of the feed delivered to and distributed by the spreader.
