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.

A shrimp processing machine includes a frame assembly, a drive assembly coupled therewith, a bracket member, and an adjustable cutting assembly. The adjustable cutting assembly is movable between a raised position and a lowered position and includes a cutting device and an adjustable cam plate operably coupled with the cutting device. The adjustable cam plate has a cam body, an adjustment mechanism, and an engagement region having first, second, and third engagement surfaces. The adjustable cutting assembly is adjustable between a first configuration whereby the cutting device has a slow drop-in rate and a second configuration whereby the cutting device has a fast drop-in rate.

Method and apparatus for a handheld tool having a handle on one end along with a blunt ended probe-like arcuate shaped portion on the opposite end which probe is inserted into the shrimp for simultaneously peeling and deveining the shrimp. The handle is designed for being grasped in the hand of a user. The probe has a base-like ricasso portion which acts as a stop for the body of the shrimp so that when the body of the shrimp is pushed against the ricasso the meat is removed from the shrimp by separating the meat from the shell of the shrimp. In operation, the device or tool is inserted along the back of the shrimp at the dorsal portion of the shell and the shrimp is pushed forward and pinched at the same time so that the shrimp is peeled and deveined simultaneously.

A method for inspecting peeled shrimp by human operators in a culling station illuminated by ambient visible light and in a dark shell-detection booth illuminated by ultraviolet (UV) lamps. The UV radiation emitted by the lamps is filtered to remove visible light from the filtered UV irradiating the shrimp in the dark booth. Irradiated shrimp shell fluoresces and is detectable by the naked eye. A human operator in the dark booth detects the fluorescing shell and removes those shrimps.

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.

A shrimp processing method and system, the system comprising a plurality of clamps, wherein each clamp is configured to hold a shrimp proximate a tail of the shrimp, a plurality of processing stations comprising at least one data collection station capable of collecting data regarding a shrimp held in a clamp and at least one functional station capable of changing the shrimp held in a clamp, a conveying system connecting the plurality of processing stations, the conveying system configured to move the plurality of clamps between the processing stations, and a controller operably connected to the conveying system and the processing stations, the controller configured to operate the conveying system and to selectively activate each processing station.

Shrimp processing apparatus to 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 remove of pleopods of individual shrimp.

Shrimp peeling machine (1) including a closed chain (3) including cylindrical rolls (4,5,6), (7) and includes first rolls (4), second rolls (5) and third rolls (6) and where at least the first (4) and second (5) rolls in a limited areathe peeling area (8)are designed to turn by an activation element (9). The shrimp peeling machine (1) includes a first motor device (10), which drives the activation element (9) and another motor device (11), which drives the chain (3) forwards in the shrimp peeling process direction (7). The activation element (9) includes at least one toothed belt (12) with a first action surface (13) and another action surface (14). The first action surface (13) is with first items (15) in mesh with the first roll (4) and the second action surface (14) is with second items (16) in mesh with the second roll (5).

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.

The invention relates to a fishing system (102), a fish processing line (18, 22) and/or vessel (2) provided therewith, and a method (26) therefor. The fishing system (102) according to the invention comprises a fishing net (6) for catching shrimps or fish; transfer means (14, 15, 16) connected operatively to the fishing net (6) for bringing on board the caught shrimps or fish; an automatic detection device (18) configured to detect, classify and if desired sort the shrimps or fish brought on board; a registration system (104) connected operatively to the detection device (18) and configured to receive, store and read and/or transmit data (108) obtained with the detection device (18) about the shrimps or fish brought on board, wherein the data (108) comprise information about the quantity, classification and location of the caught shrimps or fish.
