Cleaning

Cleaning grains after harvest is important as it removes unwanted materials from the grain.

A clean grain has a higher value than a grain that is contaminated with straw, chaff, weed seeds, soil, rubbish, and other non-grain materials.

Grain cleaning will improve the drying, the storability of grain, reduce dockage at time of milling, and improve milling output and quality; while, seed cleaning will reduce damage by disease, and improve yields.
