Abstract
A method for manufacturing coextruded products by coextruding continuous strands of one extrudable material and enveloping sheaths and twisting these sheathed strands about each other for at least part of a full revolution. An apparatus for manufacturing such products comprises a multiplicity of nozzles each having a central bore with feeding means and an annular opening surrounding this bore having separte feeding means, which nozzles are arranged for mutual movement comprising at least part of a rotation.
Claims5
A method for manufacturing co-extruded food products, comprising:
- extruding a first continuous strand of one extrudable food material, simultaneously extruding an enveloping sheath of a second continuous strand of a different extrudable food material while rotating said first and second strands, thereby twisting said first and second strands about each other for at least part of a full revolution.
An apparatus for manufacturing co-extruded food products comprising a multiplicity of nozzles, each of said nozzles comprising a central bore and an annular opening surrounding said central bore, said central bore and said annular opening being connected to separate feeding means;
- and means for rotating said nozzles thereby effecting a mutual movement which comprises at least part of a rotation about each other.
