RESPECTED TEACHER,

HOPE SO U WILL ANSWER MY QUESTION.

The correct term is threshing.
The process of separating grains from stalks is called threshing. It can be done manually by beating the bundles of stalk with sticks to separate the grains. Machines known as threshers are also used to thresh large quantities of grain.
