Abstract

A process for simplified production of a reference milling for determining the milling quality of wheat, includes: a first crushing of a wheat sample; a first sieving of the crushed product into three distinct levels of particle size; a second crushing of oversize particles resulting from the first crushing; a second sieving of the oversize particles thus crushed; a mixing of coarse semolina resulting from the sievings; a third crushing of the mixture of the coarse semolina; a third sieving of the mixture of the coarse semolina thus crushed into two distinct levels of particle size; a mixing of fine semolina resulting from each of the three sievings; a fourth crushing of the mixture of fine semolina; a fourth sieving of the mixture of the fine semolina thus crushed into a single level of particle size; a mixing of the flours resulting from sievings, the mixture constituting the desired milling.

Dependent claims

A process for simplified production of a reference milling for determining a milling quality of wheat, comprising the steps of:

a first crushing (B1) of a wheat sample into a crushed product;
a first sieving (T1) of the crushed product into three distinct levels of particle size to produce four first products:
oversize particles (Re), first-crushing coarse semolina, first-crushing fine semolina, and first-crushing flour (FB1);
a second crushing (B2) of the oversize particles (Re) to produce crushed oversize particles;
a second sieving (T2) of the crushed oversize particles into three distinct levels of particle size to produce four sorted second products:
coarse bran (GS), second-crushing coarse semolina (Gs), second-crushing fine semolina and second-crushing flour (FB2);
a mixing of the first-crushing coarse semolina and the second-crushing coarse semolina to produce a mixture of coarse semolina;
a third crushing (C1) of the mixture of coarse semolina to produce a crushed mixture of coarse semolina;
a third sieving (T3) of the crushed mixture of coarse semolina into two distinct levels of particle size to produce three sorted third products:
fine bran (FS), third-crushing fine semolina and third-crushing flour (FC1);
a mixing of the first-crushing fine semolina, the second-crushing fine semolina, and the third-crushing fine semolina to produce a mixture of fine semolina;
a fourth crushing (C1) of the mixture of fine semolina to produce a crushed mixture of fine semolina;
a fourth sieving (T4) of the mixture of fine semolina (Fs) into a single level of particle size to produce two sorted fourth products:
sharps (Rem) and fourth-crushing flour (FC1);
and
a mixing of the first-crushing flour (FB1), the second-crushing flour (FB2), the third-crushing flour (FB3), and the fourth-crushing flour (FB4) to produce a milling (M).

13 more elements

A device for grinding wheat, comprising:

four successive crushers, each of said crushers in communication with a sieving system,
wherein first and second crushers (B1, B2) produce only three levels of particle size, a third crusher (Cl) following the second crusher (B2) produces only two levels of particle size, and a fourth crusher following the third crusher (Cl) produces a single level of particle size, and
wherein the device is configured to operate such that
the first crusher performs a first crushing (B1) of a wheat sample into a crushed product,
the sieving system performs a first sieving (T1) of the crushed product into three distinct levels of particle size to produce four first products:
oversize particles (Re), first-crushing coarse semolina, first-crushing fine semolina, and first-crushing flour (FB1),
the second crusher performs a second crushing (B2) of the oversize particles (Re) to produce crushed oversize particles,
the sieving system performs a second sieving (T2) of the crushed oversize particles into three distinct levels of particle size to produce four sorted second products:
coarse bran (GS), second-crushing coarse semolina (Gs), second-crushing fine semolina and second-crushing flour (FB2),
the third crusher performs a third crushing (Cl) of a mixture of the first-crushing coarse semolina and the second-crushing coarse semolina to produce a crushed mixture of coarse semolina,
the sieving system performs a third sieving (T3) of the crushed mixture of coarse semolina into two distinct levels of particle size to produce three sorted third products:
fine bran (FS), third-crushing fine semolina and third-crushing flour (FCl),
a fourth crusher performs a fourth crushing (C1) of a mixture of the first-crushing fine semolina, the second-crushing fine semolina, and the third-crushing fine semolina to produce a crushed mixture of fine semolina, and
the sieving system performs a fourth sieving (T4) of the mixture of fine semolina (Fs) into a single level of particle size to produce two sorted fourth products:
sharps (Rem) and fourth-crushing flour (FC1),
a mixture of the first-crushing flour (FB1), the second-crushing flour (FB2), the third-crushing flour (FB3), and the fourth-crushing flour (FB4) producing a final milling product (M).
