Threshing
- Threshing is the process of beating paddy plants in order to
separate the seeds or grains from the straw.
- Threshing is one of the many tasks a combine harvester performs,
along with harvesting the plant and cleaning the grains.
- To maintain the high quality of the harvested grains, it should
be threshed immediately after harvesting.
- Avoid field drying and stacking for several days as it affects
grain quality due to over drying. Stacked grains of high moisture
content results in discoloration or yellowing.
- Threshing can be done manually or mechanically. The manual
methods of threshing are treading by feet, flail method, and beating
stalks against tubs, boards or racks. Mechanical threshing removes
rice grains from the rice plant, speeds up threshing (thus reducing
losses), and reduces labor requirements. Although once done by hand
using a flail on a threshing floor, this tiring task is now mostly
done by machine.
