Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
82 words
A process for conditioning strands of food material which comprises forming a dough of said food material, forming said dough into a plurality of strands, passing each said strand individually through a separate elongated, vertical zone of positive air pressure, all of said elongated, vertical zones being located in a larger zone of positive air pressure, the air in said larger zone being under greater pressure than the air outside of said larger zone, and thereafter cutting the said strands into pieces.
Claim 2
Dependent Claim
82 words
A process for conditioning strands of food material which comprises forming a dough of said food material, forming said dough into a plurality of strands, passing each said strand individually through a separate elongated, vertical zone of positive air pressure, all of said elongated, vertical zones being located in a larger zone of positive air pressure, the air in said larger zone being under greater pressure than the air outside of said larger zone, and thereafter cutting the said strands into pieces.
Claim 3
Dependent Claim
14 words
A process as defined in claim 1 wherein said dough contains a starchy material.
Claim 4
Dependent Claim
20 words
A process as defined in claim 2 wherein said dough is continuously formed into at least one strand by extrusion.
Claim 5
Dependent Claim
20 words
A process as defined in claim 3 wherein said dough becomes heated during said extrusion sufficiently to gelatinize the starch.
Claim 6
Dependent Claim
12 words
A process as defined in claim 1 wherein said strands are hollow.
Claim 7
Dependent Claim
48 words
A process as defined in claim 1 wherein each of said plurality of extruded food strands is gravity fed into a separate elongated zone of directed air flow wherein it is subjected to a downward flow of air and wherein it is completely surrounded by said air flow.
Claim 8
Dependent Claim
33 words
A process as defined in claim 6 wherein a substantial portion of air in said zone is conditioned air which has been treated to adjust the humidity and temperature to a predetermined level.
