Abstract
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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
92 words
A method for manufacturing a puffed snack, said method comprising: preparing, in an extruder, ingredients of dough to be formed into a puffed snack; extruding the dough in the form of a rope from the extruder; spraying a coating solution or water to a surface of the dough extruded from the extruder; drying the sprayed extrudate until a moisture content of the sprayed extrudate becomes 5 to 12% by weight; cutting the extrudate to form the puffed snack after said spraying and drying; and further drying the puffed snack after said cutting.
Claim 2
Independent Claim
92 words
A method for manufacturing a puffed snack, said method comprising: preparing, in an extruder, ingredients of dough to be formed into a puffed snack; extruding the dough in the form of a rope from the extruder; spraying a coating solution or water to a surface of the dough extruded from the extruder; drying the sprayed extrudate until a moisture content of the sprayed extrudate becomes 5 to 12% by weight; cutting the extrudate to form the puffed snack after said spraying and drying; and further drying the puffed snack after said cutting.
Claim 3
Dependent Claim
82 words
A method for manufacturing a puffed snack according to claim 1 , wherein said spraying, drying and cutting are carried out while the dough extruded from the extruder, in the form of a rope, is being clamped between belts which are spanned respectively in a tensioned state over two pairs of drawing rolls arranged on opposite sides of an extruding route of the extrudate so that the belts face each other, and while the extrudate is being drawn out from the belts.
Claim 4
Dependent Claim
41 words
A method for manufacturing a puffed snack according to claim 1 , wherein main ingredients of the puffed snack are either one kind or a mixture of two or more kinds of milled grains, flours, root vegetable flours and pulse flours.
Claim 5
Dependent Claim
43 words

Claim 6
Dependent Claim
29 words
A method for manufacturing a puffed snack according to claim 1 , wherein said cutting is performed at right angles with respect to a central axis of the extrudate.
Claim 7
Dependent Claim
40 words
A method for manufacturing a puffed snack according to claim 1 , wherein said cutting is performed at an angle of inclination in a range of 15 to 60 degrees inclusive with respect to a central axis of the extrudate.

Claim 13
Dependent Claim
40 words
A method for manufacturing a puffed snack according to claim 4 , wherein said cutting is performed at an angle of inclination in a range of 15 to 60 degrees inclusive with respect to a central axis of the extrudate.
Claim 14
Dependent Claim
201 words
A method for manufacturing a puffed snack according to claim 2 , wherein said method is performed using an apparatus for manufacturing the puffed snack, said apparatus comprising: said extruder attached with a die having a nozzle hole provided therein, at a tip portion of said die, for extruding a rope-shaped dough therefrom; a spray device for carrying out said spraying and having at least one spray nozzle for uniformly spraying the surface of the rope-shaped dough extruded from said nozzle hole; a drying device for carrying out said drying and being arranged adjacent to said spray device on the downstream side of said spray device; a drawing mechanism comprising said belts spanned in a tensioned state so as to clamp the extrudate, over said two pairs of drawing rolls arranged on the opposite sides of the extruding route of the extrudate so that said belts face each other; a holding cylinder for holding the extrudate and being arranged at an end on a downstream side of the extruding route of the extrudate; and a cutting blade for carrying out said cutting and being arranged in close proximity to an outlet side opening of said holding cylinder to cut the extrudate.
