At harvest time rice grain contains a lot of moisture, typically between 20-25%. At such high grain moisture contents (MC) there is increased natural respiration in the grain that causes deterioration of the rice.

The purpose of drying is to reduce the moisture content of rough rice to a safe level for storage. As even short term storage of high moisture paddy rice can cause quality deterioration, it is important to dry rice grain as soon as possible after harvesting - ideally within 24 hours.
