Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
A method of preparing corn powder consisting of the steps of (a) picking corn at a sufficient time period of the normal growing cycle before being ripened and field dried so that it contains between 35 and 45 percent fluid by weight; (b) removing the kernels from their associated cobs; (c) heating said separated kernels at a temperature between 125° F. and 150° F. for between 2 and 21/2 hours; (d) subjecting said heated kernels to an airstream to separate flake-like coverings surrounding the kernels which form a residue, and blowing the residue therefrom; and (e) grinding the kernels into a powder having a texture between that of coarse and fine corn powder.
Claim 2
Independent Claim
113 words

Claim 3
Dependent Claim
13 words
The method of claim 1, wherein the kernels are heated in an enclosure.
Claim 4
Dependent Claim
29 words
The method of claim 2, wherein the heated kernels are fed into a residue separator having openings in the walls thereof through which said airstream is caused to flow.
Claim 5
Dependent Claim
23 words
The method of claim 3, wherein the air blown kernels pass downwardly through said residue separator and are then ground into a powder.
