A farmer in India threshes grain by hand. An animal-powered thresher.

Other threshing machines would discharge grain from a conveyor, for bagging by hand. Combines are equipped with a grain tank, which accumulates grain for deposit in a truck or wagon. A large amount of chaff and straw would accumulate around a threshing machine, and several innovations, such as the air chaffer, were developed to deal with this.

Hundreds of millions of tones of wheat, barley, maize, soybean, rice and other grains as sorghum, sunflower seeds, rapeseed/canola, oats, etc., are dried in grain dryers annually. [2] In the main agricultural countries, drying comprises the reduction of moisture from about 17-30% w/w(water personne weight) to values between 8 and 15%w/w ...
