What is threshing rice?

Threshing rice is the process of separating the edible grains from the straw and chaff. Traditionally, it was done by beating the harvested rice plants with sticks or flails to remove the grains. Today, modern rice threshers are used to automate the process.

There are two primary types of rice threshers: axial flow threshers and drum threshers. Axial flow threshers use a series of rotating spikes to gently pull the rice grains off the stalks and separate them from the straw and chaff. Drum threshers, on the other hand, use a rotating drum with teeth to separate the grains from the straw.

The threshed grain is then cleaned to remove any remaining impurities, such as dust and small pieces of straw, before being stored or processed further. The straw and chaff can be used as animal feed, fuel, or fertilizers.

Threshing rice is an important step in the rice harvesting process, as it is crucial to separate the grains from the inedible parts. Efficient and effective threshing can improve the yield and quality of rice crops, helping to increase food production and improve livelihoods in rice-growing regions.
