Abstract

1,047,084. Preserving and shelling crustaceans. MASCHINENFABRIK BUCKAU R. WOLF A.G. Jan. 30, 1964 [Feb. 1, 1963; Aug. 23, 1963], No. 4028/64. Headings A2D and A2U. In preserving and shelling crustaceans, such as shrimps and prawns, freshly caught crustaceans are boiled in water or a desired aqueous liquid and cooled, in air and then in a refrigerator, to a temperature between 1 aid 4‹C. They are then freeze-dried and their shells are mechanically broken up and detached from the meats, as by feeding the freeze-dried crustaceans through the nip between two elastic, resilient and gripping surfaces, one of which moves relatively to the other, which is preferably stationary. Suitable shelling apparatus comprises a roller 1, rotating in the direction indicated by the arrow A, curved with an elastic, resilient covering 3, e.g. of profiled rubber having an underlying base of foamed material, a concentric curved fixed plate 2 covered with elastic and resilient coverings 4 and 5, of which covering 4 is harder than covering 5, a perforated delivery screen 7 and a centrifuging roller 10 rotating rapidly in the opposite direction to the roller 1. The freeze-dried crustaceans are fed, by an endless conveyer belt 8, along a shoot 9 into a narrowing, wedge-like passage 6 between the coverings 3 and 4. As the crustaceans are carried through the nip between coverings 3 and 4 and 3 and 5, their heads and tails are torn off, and their shells are torn open, detached from the meat and broken up. The resulting mixture of meats and broken shells then passes over the screen 7, through which most of the broken shells pass into a receptacle 14. The meats and remaining pieces of shell fall on to the roller 10, which flings meats into a receptacle 12 and pieces of shell into a receptacle 13. A suction device 15 may be provided, over the screen 7, to remove lighter pieces of shell. Alternatively a blower may be provided near the screen 7, to blow or winnow away the lighter pieces of shell. The whole apparatus may operate in a protective gas, such as nitrogen or carbon dioxide in a surrounding chamber.
