Abstract

911,977. Prawns &C. shelling. ASSOCIATED FISHERIES & FOODS (FLEETWOOD) Ltd. April 21, 1960 [April 24, 1959; May 9, 1959], Nos. 14014/59 and 15991/59. Class 28 (2). The flesh is ejected from the shell tail of a headed shrimp &c. by fluid pressure (air), injected at the anus G, Fig. 1, by a nozzle 33 (Fig. 3) moved by an air cylinder 30 to penetrate the shell. The tails, placed by hand on a conveyer, are blown into one of the troughs 23 of an endless conveyer 24 moved intermittently through a Geneva mechanism. The tail upside down is gripped therein by a descending pad 46 and then a water-pressure jet 52 (Fig. 6) drives out the sand vein, the jet 52 being in register with the adjacent sand vein end. The conveyer carries the tail to the next station where the air nozzle 33 is moved to penetrate the shell at the anus and supply a blast of air to blow the flesh out of the shell. The blown-out flesh is arrested and conveyed away, while the tail shell is blown out by another blast of air, by a third endless belt conveyer moving with the second endless conveyer 24. The various nozzles are supplied with fluid and actuated by a camshaft 13. Specification 911,979 is referred to.
