摘要:
In the mechanized peeling of shrimp, first (211) and second (212) contacting means are brought in contact with the underside and topside of the shrimp (2), respectively. Squeezing means (214) exert, via said contacting means, a pressing force onto the shrimp. The pressing force moves in a squeezing direction extending from the head and the tail towards the back of the shrimp, so that the armature of the shrimp opens on the backside and the meat of the shrimp is squeezed out of the armature. During exertion of said pressing force, one or each of said contacting means, when seen in cross-section transverse to said squeezing direction, has a recessed shape (215) on its side facing towards the shrimp. At least a part of that recessed shape embeds the shrimp during the exertion of said pressing force.

A method of preparing shrimps comprises the following steps: Steam boiling the shrimps at a high pressure exceeding the atmospheric pressure, and at an elevated temperature exceeding the boiling temperature of water at the atmospheric pressure for a specific period of time for keeping the meat of the shrimps in a compressed state due to the pressurisation while rapidly heating the shrimps to the elevated temperature for causing the meat of the shrimps to solidify and cause the meat of the shrimps to loosen from the shells of the shrimps. The shrimps are then rapidly cooled to a temperature to or below the atmospheric temperature for causing substantially all meat of the shrimps to be separated from the shells of the shrimps between an area behind the head of the individual shrimp and a part above the tail of the individual shrimp. Subsequently, the shrimps are peeled by mechanically opening the shells of the shrimps for allowing the meat loosely contained within the shells of the shrimps to fall out from the shells of the shrimps, and the meat of the shrimps is separated from the remainings of the shrimps, including the shell parts and any eggs by flotational separation of the meat from the remainings by introducing the meat and the remainings into a separation liquid such as a brine solution, including a specific amount of NaCl by weight for causing the meat to float on the separation liquid while allowing the remainings of the shrimps, including the shell parts and any eggs to sink. Finally, the meat is removed from the separation liquid.
摘要:
Apparatus for evaluating a part of a seafood animal such as a lobster claw, to determine the ratio of meat to water and other characteristics, including first and second transducers (12, 14) that are coupled to spaced locations on the part P of the animal so when the first transducer transmits sonic energy it passes through the animal part to the second transducer. A circuit (34) coupled to the second transducer analyzes detected sonic energy. In one system, the circuit calculates the velocity of sound through the part of the seafood animal. A higher velocity indicates a higher meat content. Another circuit includes an indicator that indicates the amplitude of sound detected by the second transducer, especially the amplitude of sound of the predominant frequency generated by the first transducer, that has passed directly through the animal part. A lower amplitude indicates a higher meat content. A pressure sensor (124) automatically activates the first transducer to generate sonic energy, when the transducers are pressed with a predetermined force against the part of the seafood animal. The transducers can be mounted on a glove (92) between the thumb (T) and an opposed finger (F), so the part can be tested when it is picked up by a person wearing the glove.

A method and an apparatus for mechanically removing the meat from a crustacean is provided, which include the steps of loading the tail of the crustacean onto guide means (18), extending the tail so that it assumes a substantially horizontal position, piercing the tail with the tip (44) of a nozzle (40) connected to a source of pressurized fluid, separating the head and abdominal portions of the crustacean from the tail, and expelling the meat from the tail by means of the pressurized fluid from the nozzle tip impinging on the meat.
