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-production grain losses

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

EVALUATION OF POST-HARVEST LOSSES IN RICE PROCESSING

An enormous quantity (25%) of rice is lost during processing of rice along the unit operations and the losses are variety specific. The effect of heat treatment (steaming) on the physical properties of different rice varieties were carried out to investigate the relationship between biophysical properties and mechanical properties of different rice varieties.

Postharvest technology: Rice storage and cooling ...

01/01/2019 By using a grain cooling device, losses can be significantly limited as the respiration activity is reduced at lower storage temperatures and the mass losses are negligible. In addition to respiration, additional mass loss in the rough rice can occur due to insects, fungi, and bacteria. According to estimates by the Food and Agriculture ...

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.
