This process is called "winnowing" - separating the wheat from the chaff (rubbish). Air streams are used to separate the rubbish from the heavier wheat grains.Back to Top
When the rubbish has been removed the grain is then taken by elevator up a floor to the Stoner.
This is a sloping table which vibrates and the heavier stones are shook out and collected to be thrown away. Magnets are used to remove bits of iron and steel.Back to Top
The wheat is then taken to a machine called a Scourer. This loosens the skin of the wheat and removes the "beard" - the hairy bit at the top of the grain.Back to Top
