Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
95 words
A method for preparing an expanded wheat product comprising the steps of grinding whole wheat, adding moisture to the ground wheat, uniformly distributing the moisture in the ground wheat to make a dough, conducting the dough to a die, heating the dough by passing it through the die at a rate sufficient to generate heat and steam in the dough without any external heat source to the die and cook the dough in the die to condition the wheat and extruding the dough into a lower pressure zone to flash steam and expand the dough.
Claim 2
Independent Claim
95 words
A method for preparing an expanded wheat product comprising the steps of grinding whole wheat, adding moisture to the ground wheat, uniformly distributing the moisture in the ground wheat to make a dough, conducting the dough to a die, heating the dough by passing it through the die at a rate sufficient to generate heat and steam in the dough without any external heat source to the die and cook the dough in the die to condition the wheat and extruding the dough into a lower pressure zone to flash steam and expand the dough.
Claim 3
Dependent Claim
16 words
A method as recited in claim 1, wherein said wheat has at least 11 percent protein.
Claim 4
Dependent Claim
22 words
A method as recited in claim 1, wherein said dough has from about 14 percent to about 18 percent by weight moisture.
Claim 5
Dependent Claim
21 words
A method as recited in claim 1, wherein said dough is extruded at a rate of about 1,000 pounds per hour.
Claim 6
Dependent Claim
17 words
A method as recited in claim 1, wherein said lower pressure zone is at about atmospheric pressure.
Claim 7
Dependent Claim
23 words
A method as recited in claim 1, wherein said wheat has a particle size no greater than the minimum dimension of said die.
Claim 8
Dependent Claim
29 words
A method as recited in claim 1, wherein said dough is extruded into said lower pressure zone forming an expanded product which has the shape of a pork curl.
Claim 9
Dependent Claim
240 words
A method as recited in claim 1 wherein the die comprises three interfacing plates which include an upstream plate, an intermediate plate and a downstream plate each with an upstream and downstream face, said dough being extruded in the downstream direction; the upstream plate including a plurality of upstream plate apertures each of the upstream apertures being surrounded by a feed cavity in the downstream face of the upstream plate, the plurality of upstream plate apertures terminating in a recess in the downstream face of the upstream plate; the intermediate plate having a plurality of intermediate apertures in a plurality of intermediate arrays each of the arrays having a center which is substantially opposed to the center of the upstream plate apertures, the upstream face of the intermediate plate having an intermediate boss extending therefrom interfacing with the downstream face of the upstream plate, the intermediate apertures extending through the intermediate boss, the downstream face of the intermediate plate having a bead and a plurality of pegs extending therefrom, the pegs extending substantially from the center of each of the intermediate arrays and each of the pegs being surrounded by an intermediate feed cavity; the downstream plate having a plurality of downstream apertures tapering down into openings in the downstream face of the downstream plate, the pegs extending from the intermediate plate into the downstream apertures forming an exit port in the die between the pegs and the downstream apertures.
Claim 10
Dependent Claim
34 words
A method as recited in claim 8 wherein said dough has from about 14 percent to about 18 percent by weight moisture and is extruded at a rate of about 1000 pounds per hour.
Claim 11
Dependent Claim
99 words
A method as recited in claim 1 wherein said die comprises two interfacing plates which include an upstream plate and a downstream plate each with an upstream and a downstream face, said dough being extruded in the downstream direction; the upstream plate including a plurality of upstream apertures, the upstream apertures being surrounded by a feed cavity in the downstream face of the upstream plate; the downstream plate having a plurality of downstream apertures offset from the upstream apertures, the downstream apertures tapering down to the downstream face of the downstream plate forming an exit port in the die.
Claim 12
Dependent Claim
21 words
A method as recited in claim 10 wherein the downstream apertures are slots offset on a circumference surrounding the upstream apertures.
Claim 13
Dependent Claim
34 words
A method as recited in claim 8 wherein said dough has from about 14 percent to about 18 percent by weight moisture and is extruded at a rate of about 1000 pounds per hour.
Claim 14
Independent Claim
44 words
A method as recited in claims 1, 2, 3, 4, 5 6, 8 or 10 wherein said heat and steam are generated in said dough and said dough is cooked in said die without any external heat source to said dough and said die.
