Grain losses in rice processing - Food and Agriculture ...

Grain losses in rice processing. Losses from Drying the Paddy. Sun drying is the traditional method of drying the harvested rice crop. The crop is either left in wind rows in the field to dry (after reaping but before threshing), or spread out on mats or on pavements after threshing. During the wet season, if there is no artificial drying capacity, it is not uncommon for the grain

Post-harvest losses (grains) - Wikipedia

The main cause of loss during drying is the cracking of grain kernels that are eaten whole, such as rice. Some grains may also be lost during the drying process. However, failure to dry crops adequately can lead to much higher levels of loss than poor-quality drying, and may result in the entire harvest becoming inedible. Adequate drying by farmers is essential if grains are to be

Paddy Drying Process in Rice Mills

19/01/2017  At the time of harvest, the moisture content of the rice grains ranges between 18 -25%. Post the harvest, the most critical operation is paddy drying. Drying reduces the moisture content in the grain which is a requisite if it is to be stored. Delaying the drying process or drying it unevenly would result in a qualitative loss.
