US 6,632,466 B2 · Coextrusion method with coextrusion hollow needles

Abstract

A method for producing a food product including a solid casing coating at least one stuffing in a coextrusion device including a coextrusion die fed with a proteic base and a stuffing material. The method including forming in a first section of the die the casing which solidifies via a thermic effect. The first section being longitudinally traversed by at least one hollow needle for transferring the stuffing, one hollow needle per stuffing material, and penetrating into a second section of the die. Stuffing the second section of the die including the solid casing formed in the first section of the die with the stuffing material coming out of the hollow needle traversing the first section. Recovering the product, including the external casing filled with the stuffing material, at the outlet of the die.

Dependent claims

A method for producing a food product having a solid external casing, the food product including at least one casing material from a food base, for forming the casing of the food product, and at least one stuffing food material, the food product formed in a coextrusion device comprising a coextrusion die fed with the food base and the stuffing food material, the method comprises the following successive steps:

forming in a first section of the die the casing which solidifies by cooling, said first section being traversed longitudinally by at least one hollow needle for transferring the stuffing food material, one hollow needle per stuffing food material, and penetrating a second section of the die, the beginning of the second section being defined by the outgoing extremity of a shortest hollow needle;
stuffing in a second section of the die the solid casing formed in the first portion of the die with the stuffing food material coming out of the at least one hollow needle traversing the first section;
and
recovering the product comprising the external casing filled with the stuffing food material at an outlet of the die.

A method for producing a food product, the food product comprising a casing, for coating at least one stuffing food material, the casing including at least one casing material from a food base, the food product being formed in a coextrusion device having a die and a hollow needle, the method comprising:

(a) forming in a first section of the die the casing which solidifies by cooling, the first section being traversed longitudinally by the hollow needle for transferring the stuffing food material;
(b) stuffing in a second section of the die the casing formed in the first section of the die with the stuffing food material coming out of the hollow needle traversing the first section, the beginning of the second section of the die being substantially defined by the extremity of a shortest hollow needle;
and
(c) recovering the food product comprising the casing filled with the stuffing food material at an outlet of the die.
