METHOD AND APPARATUS FOR EXTRUDING FOOD PRODUCTS

摘要

A food product is extruded as an elongate billet (14) from the head (10) of a mandrel (1). The mandrel (1) has inner and outer passages to dispense a solid core (A) (e.g. meat) and a more mobile annular coating (B) (e.g. fat). The product comprises an outer casing (13) of plastics dispensed from the mandrel onto the product as it emerges from the extrusion head.
