A crab cracking tool. The crab cracking tool includes a first member having a first handle connected to a first head portion and a second member having a second handle connected to a second head portion. The first head portion includes a first recess, a second recess, and a first gripping portion and the second head portion includes a third recess, a fourth recess, and a second gripping portion. A cutting tool disposed on the second member extends outwardly from a first end of the second head portion. The cutting tool includes an inner edge having a blade thereon. The inner edge is oriented inwardly toward an outer side of the second member defining an opening therebetween. The first member is pivotally secured to the second member, such that the first second members are configured to pivot between a closed position and an open position.

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.

A crustacean butchering apparatus is disclosed. The crustacean butchering apparatus may include at least one carapace grip sized to secure a carapace of a crustacean to a conveyor. When activated, the conveyor carries the crustacean secured by the carapace grip in a machine direction along a processing path. A plurality of tools may be placed along the processing path for butchering the crustacean. Optionally, a claw removing tool may be positioned along the processing path. When activated, the claw removing tool separates at least one claw of the crustacean from the carapace of the crustacean. Optionally, a tail removing tool may be positioned along the processing path. When activated, the tail removing tool may separate a tail of the crustacean from the carapace of the crustacean.

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.

An apparatus for removing meat from crustacean legs includes a conveyor, and a plurality of leg meat extraction rollers. The conveyor has a crustacean body region flanked by laterally opposed crustacean leg regions. Each crustacean leg region includes a plurality of leg slots extending laterally outwardly of the crustacean body region. The leg meat extraction rollers are positioned laterally outwardly of the leg slots and oriented to receive crustacean legs moved laterally outwardly from the leg slots.

Moisture is retained in cooked or thawed food by adding to the food an aqueous suspension of animal muscle protein obtained from animal muscle tissue. The aqueous suspension is obtained by mixing comminuted animal muscle tissue with a food grade base to form an aqueous basic solution of animal muscle protein. The basic solution is mixed with a food grade acid to precipitate the protein in an aqueous composition. The precipitated protein then is comminuted to form an aqueous suspension of comminuted animal muscle protein.

A utensil to open a shell of a shellfish, including a first end including a shell breaking tool, a second end including a fork, and a handle to connect the first end to the second end, such that at least a portion of a bottom surface of the handle includes a sharpened edge.

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.
