#CMT# #/CMT# The inner casing (10) is pulled through a pipe (40), while an outer casing (50) is pulled over a caliber disc (60) at the exit of the pipe and over the inner casing to form a combination of casings. The combination is pulled into a shirring horn (100) via feeding cylinders (110) of the shirring machine (70), and is then shirred to produce a compact tube. The tube is cut into sticks or caterpillars of given lengths. #CMT# : #/CMT# An independent claim is also included for a composite casing shirred to a stick. #CMT#USE : #/CMT# For producing shirred tubular composite casings for food products e.g. scalded sausages, cheese or cheese-like products, fish products, vegetable products, as well as meat and poultry products. #CMT#ADVANTAGE : #/CMT# Shirred casings may be formed without using adhesives or binding components, making such casings ready to use for food products. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# Figure is a perspective view of a shirred composite tubular casing production process. 10 : Inner casing 40 : Pipe 50 : Outer casing 60 : Caliber disc 70 : Shirring machine 100 : Shirring horn 110 : Feeding cylinders #CMT#POLYMERS : #/CMT# The inner casing is formed of collagen based on regenerated or modified cellulose or on thermoplastic starch and/or its derivatives, polyurethanes, paper, textile fibers, or paper impregnated with alginate, non-woven materials, or plastic based on e.g. polyamide, polyolefin, polyester, polyvinylidene chloride, polyvinyl chloride, polystyrene, ethylene vinyl alcohol (EVOH), ethylene vinyl acetate (EVA), ethyl methyl acrylate (EMA), ethylene ethyl acrylate (EEA), block copolymers of polyethers and polyamides or combination thereof. The adhesion improver for the casings consist of cationic polyamide epichlorohydrin resin with 0.004 to 0.04 percent by weight. The outer casing is formed of plastic based on e.g. polyamide, polyolefin, polyester, polyvinylidene chloride, polyvinyl chloride, polystyrene, ethylene vinyl alcohol (EVOH), ethylene vinyl acetate (EVA), ethyl methyl acrylate (EMA), ethylene ethyl acrylate (EEA), block copolymers of polyethers and polyamides, or combination thereof, or of collagen based on regenerated or modified cellulose or on thermoplastic starch and/or its derivatives, polyurethanes, paper, textile fibers, or paper impregnated with alginate, non-woven materials, or combinations thereof. The optional seamless net between casings may consist of fibers selected from cotton, linen, viscose, polyamide, polyester, polyolefin, cellulose, and elastane. The outer casing may be multi-layered consisting of polyamide outer layer, polyethylene intermediate layer, and polyamide inner layers. |
