ABSTRACT:
The present invention relates to a nozzle head for a cooking extruder for the production of a porous edible shell which is filled with an edible filling. The shell is of a breadlike character and the filling may be a sweet filling or an acid fat-containing filling.
The axis of the extruder nozzle is perpendicular to the axis of the extruder worm, and a filling tube through which a filling mass can be fed to the shell extends through the extruder nozzle.
In accordance with the invention, the filling tube 9 is surrounded by a mandrel 2 which forms with the tube an annular space 7 which separates said tube from the space conducting the molten material and extends to the outlet opening 6 of the extruder nozzle 3.
In this way the filling tube and the melt are thermally separated from each other so that the filling tube is not heated while, on the other hand, the melt is not cooled at the outlet end.
The invention also covers the method of producing a light, puffed, center-filled food product with the use of the above-mentioned nozzle head as well as the light, puffed, center-filled food product produced with the use of this nozzle head.
