| During high moisture paddy threshing, the separation losses are generally large. However,while attempting to increase cropping intensity, it is often necessary to handle the moist paddy for threshing. Furthermore, in absence of adequate sunshine hours in wet season, crop can’t be dried to a desired moisture level before threshing. Keeping these requirements in mind, a co-axial split-rotor thresher was designed for threshing high moisture paddy. This paper describes design and testing of a stationary thresher with an unequal speed co-axial split-rotor for rice in Thailand. First rotor serves mainly the threshing operation, whereas, rotating at relatively higher speed, the second rotor does mainly the separation of rice grains from husk. Faster rotation of... |
