Winnowing is the process of removing chaff from grain.
One method involves blowing air through a falling stream of grain.
The heavier grain keeps falling to a collection vessel and the chaff is blown to the side.
Cereal seeds are heavy compared to the chaff. So throwing both into a blast of air will separate the grain (which will fall first) from the chaff (which will be blown further away).
Winnow means to separate grain from chaff using the wind, as in "The farmer winnowed his wheat."
"Ancient people used to winnow their grain by tossing the threshed grain and chaff into the wind to allow the wind to carry away the chaff."

Chaff is the husk or material covering the seed. Hull, etc. Bits and pieces that are lighter than the seed and carried away by a sifting process. It means the same in the Bible. Most of the time, though, Bible writers were using it as an analogy. That is, they were making a comparison between someone's or some other nation's actions to chaff blowing away in the wind. In Bible times, chaff was separated from the grain by tossing the threshed heads into the air when there was a breeze, and allowing the wind to separate the chaff and grain. It's a practice still followed in the undeveloped and sometimes developing world.
Chaff.
Another name for a grain husk is 'hull'.
For grain, they are called "harvesters" or combine harvesters, which is a huge machine that gathers the crop (be it corn, wheat, barley, oats, etc.) and goes through the process in the machine of separating the kernels or seeds from the rest of the plant. What's left over is ejected as chaff, which can be baled for straw. In the old days, threshing machines were used to separate seeds of grain from the chaff.
There are several options: * My uncle always called them the casts. * Chaff. As in "Separate the wheat from the chaff."

The winnowing process is used in agriculture, particularly in grain production. It involves separating the chaff (outer covering of grains) from the grains themselves by tossing them in the air. The wind blows away the lighter chaff, leaving behind the heavier grains. Winnowing helps to separate the edible parts of grains from the unwanted parts.
