ABSTRACT:
A method and apparatus for manufacturing puffed snack having a hard surface layer and soft inside, and having a good texture and a difference in color tone between the surface layer and the inside. After spraying a coating liquid or water onto the surface of a dough extruded from an extruder in the form of a rope, the extrudate is dried so that the moisture content of the sprayed extrudate becomes 5 to 12% by weight and then cut. The apparatus used for this manufacturing method comprises a spray device for uniformly spraying the surface of the dough extruded from a nozzle hole of an extruder, a drying device arranged on the downstream side of the driving device, a drawing mechanism comprising belts spanned in a tensioned state so as to clamp the extrudate, a holding cylinder for holding the extrudate and arranged adjacently on the downstream side of the drawing mechanism, and a cutting blade arranged in close proximity to the outlet side opening of the holding cylinder to cut the extrudate.
