Process for the manufacture of a composite consumable product by double extrusion

摘要

A process and apparatus for the manufacture of a composite consumable product by double extrusion is described. The process involves a liquid or pastry consumable being prepared in a first section of a twin-screw extruder and a plasticizable consumable substance is cooked-extruded in a second section of the twin-screw extruder that is separated dynamically from the first. A strand of the cooked-extruded mass is obtained, cut into pieces and the liquid or pastry is then added to the cut pieces, by either coating, co-extrusion or impregnating, providing the final consumable product.
