A system for processing shellfish includes an input hopper that receives a batch of shellfish to be processed. A conveyer is positioned to receive shellfish from the input hopper and transports the shellfish through the system. The conveyor defines a plurality of holes that allow cleaning substances to pass through the conveyor. A washing system comprising a least one nozzle that dispenses cleaning substances to the shellfish being transported by the conveyor. An operator station includes at least one container for depositing market-ready shellfish passing along the conveyor. At least one optical sensor is positioned to detect the market-ready shellfish being placed into the at least one container. A counter is electrically connected to the optical sensor and records a number of shellfish being placed in the at least one container. An output hopper is positioned proximate to an end of the conveyor to catch rejected shellfish.

The present invention relates to a continuous on-board drying method for Antarctic krill and a continuous on-board processing method of shelled Antarctic krill. The drying method includes the following steps: 1) subjecting fishing materials to cleaning, sorting, and dewatering with a vibrating screen; 2) rapidly heating the krill to the temperature of up to 70 C. using infra-red rays; 3) hot-air drying; 4) impurity removal by vacuum; 5) cooling to obtain dried krill. The processing method includes the following steps: a) subjecting fishing materials to cleaning, sorting, and dewatering with a vibrating screen; b) rapidly heating the krill to the temperature of up to 70 C. using infra-red rays; c) hot-air drying; d) subjecting the dried krill to shelling treatment to separate shell from meat, to obtain shelled krill; e) impurity removal by vacuum to obtain shelled krill product. The methods in the present invention are highly efficient, energy saving, green and environmental protection, and the krill products have high quality and safety.

Methods and systems using a vision system to process shrimp. The vision system captures images of samples of shrimps. The processor produces a digital image of the shrimps in the samples. Shrimps exiting a peeler are imaged to determine the number of tail segments in each. The shrimps are classified by the number of intact segments, and quality, yield, and throughput computed from the classification results. The processor can control operational settings of the peeler based on the classification results. In a larger system including other shrimp-processing equipment besides the peeler, other points along the processing path can be imaged by camera or sensed by other sensors to determine processing quality and to make automatic operational adjustments to the equipment.

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.

Methods and systems using a vision system to process shrimp. The in-line or off-line vision system captures images of samples of shrimps. The processor produces a digital image of the shrimps in the samples. Shrimps exiting a peeler are imaged to determine the number of tail segments in or the percentage of full weight of each. The shrimps are classified by the number of intact segments, and quality, yield, and throughput computed from the classification results. The processor can control operational settings of the peeler based on the classification results. In a larger system including other shrimp-processing equipment besides the peeler, other points along the processing path can be imaged by camera or sensed by other sensors to determine processing quality and to make automatic operational adjustments to the equipment.

A shrimp processing system conveys raw peeled shrimps to an imaging chamber in which shrimp bits and shrimps with residual shell are detected and diverted from the stream of acceptable shrimps allowed to pass on to downstream processing. An ultraviolet (UV) light source in the imaging chamber is constantly on. A visual inspection system takes images of the passing stream of shrimp when a white-light source is turned on to illuminate an exposure region to detect bits, clumps of shrimps, and acceptable individual shrimps. The visual inspection system takes images of the passing stream when the white-light source is turned off and the exposure region is subjected only to ultraviolet radiation. The visual inspection system detects shrimps with residual shell in the UV images. Shrimp bits and shrimps with residual shell are diverted from the stream of shrimps by air jet nozzles to corresponding reject destinations.

A crab processor is adapted to be supported by a bucket defining a rim and an inner diameter, the crab processor comprising a main portion, a first support portion, and a second support portion. The first and second portions are attached to the main portion such that the first and second support portions define first and second portions of the main portion and a distance defined by the second portion of the main portion is less than the inner diameter of the bucket. The first and second support portions engage the rim of the bucket to support the crab processor in a desired orientation relative to the bucket.

The sorting systems and methods described herein provide for the sorting of shrimp. The sorting systems may be combined with a delivery system. The sorting systems employ a pair of rotating slides and optional guide chutes to deliver shrimp to selected delivery locations.
