Question

what is threshingmachine

Answer 1

Threshing machine is a farm machine which helps in separating seeds-grains from the corn or other crops.
 

Answer 2

thersing machine is  the process of loosening the edible part of cereal grain (or other crop) from the scaly, inedible chaff that surrounds it. It is the step in grain preparation after harvesting and before winnowing, which separates the loosened chaff from the grain. Threshing does not remove the bran from the grain.
