967,501. Coating sausage portions, chops, fish &c. P. H. HILGELAND. July 19, 1962 [July 21, 1961], No. 26622/61. Headings A2B and A2D. [Also in Division B8] Pre-shaped sausage portions, chops, small joints of meat, fish fillets and fish fingers, and other meat products are covered with an edible artificial skin in an apparatus having means for coating the products with a solution of an edible coagulable substance, for treating the coated products with a coagulating agent and for drying the products with coagulated coatings, and a conveyer system positioned to receive the products initially and to convey them during the coating, treating and drying steps. Sausages, cut-off by a device 41, preferably that described and claimed in Specification 967,502, from sausage meat extruded from a portioner filler 40, whilst on a conveyer 42 are sprayed for one second with a ¢ to 5% solution of sodium alginate circulating through a spray nozzle 43 and then drained for five seconds, whilst moving along conveyer 48 for 25 seconds are sprayed with a 10% solution of calcium chloride circulating through nozzles 51, and finally are dried for about a minute by a stream of hot air followed by a stream of cold air supplied to a tunnel 52 through which the products pass on a conveyer 49. The edges of the belts 42, 48, beneath the spray nozzles are preferably bent upwards by rollers (not shown) so that the belt is U-shaped to improve the coating or treating. The driven rollers 47a, b and 50a, b, between the conveyers further assist in the draining of liquid. In alternative embodiments the conveyers may be disposed at right angles to one another and the sprays replaced by the conveyance of the products through tanks of liquid. Specifications 902,100 and 923,680 also are referred to. |
