A process for manufacturing an expanded cereal with the overall shape of an array of touching balls and an extrusion die and an extruder for use with the process. The die includes a feed ring for receiving material from an extruder, a cylindrical distribution chamber having a front wall and rear wall which includes the feed ring, and an array of parallel extrusion tubes provided in the front wall of the distribution chamber. The feed ring is in communication with the array of parallel extrusion tubes through the distribution chamber. The distribution chamber also includes a cylindrical distribution insert that extends axially from the center of the feed ring towards the front wall but spaced from the array of extrusion tubes. The process involves cooking and extruding a mixture of starchy material, sugar, oil, and water in a cooker-extruder and forcing the cooked material through the extrusion die.

Extrusion die

An extrusion die for making shaped extrudate products has structure which defines a central duct which is convergent from a duct inlet opening to a duct outlet opening and has structure which defines a tubular extrusion duct co-axial with the central duct and which also is convergent from a duct inlet opening to a duct outlet opening. A feed diaphragm member has a portion which converges to an opening which opens to a distribution chamber which diverges so that substance being extruded is distributed to the central and tubular ducts. Diaphragms are provided in the ducts to delimit passage of extrudate substance into the ducts. Additionally, members are provided for altering the position of the central duct and its duct outlet relative to the second duct member and its outlet.

Method of manufacturing an expanded cereal

A finger-food snack containing from about 8 to 16% of whole milk solids and being in the form of a body, obtainable by cooking-extrusion-expansion of a cereal based mixture, that is coated with a sugar based slurry.

Coated snack food product

Edible cups containing an edible filling are prepared by extrusion-cooking ingredients which include a cereal ingredient and extruding an extrusion-cooked product strip, passing the product strip to a heated pressing device for hot-pressing the product strip while it is still thermoplastic to form cavities in the strip which define cup structures in a row and then, incisions are made between the cup structures, a food product filling is introduced into the cup structure cavity and the strip is cut so that filled cups are obtained.
