method for continuous manufacture of cheese or cheese specialties, installation for the implementation of the procedure and the procedure of manufactured product

摘要

For continuous prodn. of cheese product or specialised cheese foodstuff, primary ingredients are fed to screw extruder, contg. at least crushed curds and/or retentate of milk ultrafiltration. Extruder has two identical screws (12) engaging together to rotate in same direction within elongated housing (11). Ingredients are moved downstream through housing where screw (12) shape and inner housing (11) temp. during downstream movement give successive stages of compression, blending and heating to temp. of 120 deg.C. Further stage of chopping and blending is followed by decompression at 55-120 deg.C. Then compression and blending stage with heating at 55-120 deg.C is followed by chopping and blending with delivery of product into extrusion channel at 50-120 deg.C. Extrusion channel at downstream end (11b) of housing (11) gives texture, shape and chills product to be cut to required length.
