Abstract: The essence of the method of extracting or recovering meat of small crustaceans, e.g. antarctic krill, resides in that crustaceans are introduced into an air flow relative to the surface of the crustaceans at a given velocity required for creating a pressure drop across the internal space or cavity of the crustaceans and the air flow. Consequently, the inter-cavity pressure breaks up the shell and destroys the links between the muscular tissue and other components. When the crustaceans proceed along a helical path, the muscular tissue can be completely separated at the final stage of the treatment. The treatment of crustaceans is performed in stages, the air flow velocity relative to the surface of the crustaceans at the first treatment stage being about 500 m/s, at the second stage--from 200 to 300 m/s, and at the third stage--from 100 to 200 m/s.
