(A simplified diagram)

>


ELEVATOR - storage and care of wheat.

PRODUCT CONTROL - chemists inspect and classify wheat, blending is often done at this point

MAGNETIC SEPARATOR - iron or steel articles stay here.

SEPARATOR - reciprocating screens remove stones, sticks and other coarse and fine materials.

ASPIRATOR - air currents remove lighter impurities

DE-STONER

DISC SEPARATOR - barley, oats, cockle and other foreign materials are removed.

SCOURER - beaters in screen cylinder scour off inpurities and roughage.

TEMPERING MIXER - moistens wheat evenly.

TEMPERING - water toughens outer bran coats for easier separation- softens or mellows endosperm.

BLENDING - types of wheat are blended to make specific flours.

IMPACT SCOURER - impact machine breaks and removes unsound wheat.

FIRST BREAK - corrugated rolls break wheat into coarse particles.
