Drying can be done using either traditional or mechanical drying systems that have varying technological complexity and capacities for either farm or commercial level.
Traditional drying systems are still practiced in many areas because of its low cost and ease of management. These include methods, such as:
Although field drying and stacking is still practiced in some areas, it is not recommended because it can lead to high losses when grains become overdried and shattered.
In this system, mechanical dryers are used to remove water from wet grains by forcing either ambient air or heated air through the grain bulk. This is done through:
