To understand these terms, we define

Chaff = The seed heads and straw from the plant.

Threshing =
Separating the heads from the stalks.

Winnowing = Separating the grain from the chaff.

Threshing is the process of loosening the edible part of grain (or other crop) from the husks and straw to which it is attached. It is the step in grain preparation after reaping and before winnowing, which separates the grain from the chaff.

Winnowing is the agricultural process for separating grain from chaff. It involves throwing the mixture into the air so that the wind blows away the lighter chaff, while the heavier grains fall back down for recovery.

In Threshing, grains are loosened and removed from the stalk, by striking it against a stone (traditional method). Modern threshing machines carry out this process faster and in a contained environment. 

Winnowing is the process which comes after threshing. It is the process of separating grain from chaff. Traditionally the mixture is scattered to the ground from a certain height, allowing air to blow the chaff away. Winnowing machines use fans to blow away the lighter chaff from the grains.
