Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
A process for producing instantized parboiled rice which consists essentially of incorporating about 68 to about 78 weight percent water into long grain milled parboiled rice in which the starch has been substantially gelatinized, drying said water-containing rice at temperatures from about 260° F. to about 325° F. to reduce the water content of said rice to about 6 to about 14% over a period of time to obtain rice having a texture with a shear press value in the range from about 85 to about 110 lbs/force and having about a 41/2 to about 71/2 minute stand recipe when an equal volume of rice is combined with an equal volume of boiling water to produce an instantized eating quality parboiled finished rice product.
Claim 2
Dependent Claim
124 words
A process for producing instantized parboiled rice which consists essentially of incorporating about 68 to about 78 weight percent water into long grain milled parboiled rice in which the starch has been substantially gelatinized, drying said water-containing rice at temperatures from about 260° F. to about 325° F. to reduce the water content of said rice to about 6 to about 14% over a period of time to obtain rice having a texture with a shear press value in the range from about 85 to about 110 lbs/force and having about a 41/2 to about 71/2 minute stand recipe when an equal volume of rice is combined with an equal volume of boiling water to produce an instantized eating quality parboiled finished rice product.
Claim 3
Dependent Claim
25 words
The process of claim 1 wherein the water incorporated into the long grain milled parboiled cell ranges from about 72 to about 74 weight percent.
Claim 4
Dependent Claim
26 words
The process of claim 1 wherein the water content of the long grain milled parboiled rice is reduced to about 7 to about 11 weight percent.
Claim 5
Dependent Claim
26 words
The process of claim 1 wherein said drying temperatures of said water-containing long grain milled parboiled rice are from about 290° F. to about 310° F.
Claim 6
Dependent Claim
17 words
The process of claim 1 wherein the drying time ranges from about 30 to about 45 minutes.
Claim 7
Dependent Claim
20 words
The process of claim 1 wherein the shear press value ranges from about 100 to about 105 pounds per force.
Claim 8
Dependent Claim
16 words
The process of claim 1 wherein the instantized parboiled rice product has a 5 minute stand.
