Question

What is the difference between threshing and winnowing

Answer 1

WINNOWING:-
1) the process of separating dust particles with the help of wind is called winnowing.
2) mixture of grain and husk are allowed to fall from a height.
3) heavier grain falls on the ground, whereas lighter grains are carried away by the wind.

THRESHING:-
1) process of removing chaff from the grains is called threshing.
2) it is done using a stick.

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.It is a process of making natural wind to blow through the grains which allows the lighter substances to fly away leaving the heavier grains which fall on to the ground. Winnowing can be done manually. It can also be done by winnowing machine which has a fan to blow away the chaff.
