Indices of flow fruit detacher with angular vibrations at inertial threshing of sesame

Abstract

An experimental stand of flow rotational fruit detacher with asymmetric angular vibrations has been developed at the Agricultural University - Plovdiv (Bulgaria).   It is designed to detach fruits and seeds from the plants via inertial way. The aim of the presented paper was to evaluate the main indices of the flow fruit detacher at inertial threshing of non-dehiscent sesame varieties.  The results indicated that the detacher threshes over 95% of seeds without reducing their germination.   The seed moisture content is from 12.2% to 13.3%, which is two times higher than recommended for harvesting sesame with grain harvester.   The portion of the impurities in the threshed mixture is from 20.99% to 38.41% depending on varieties.   The detacher has reached 225 times higher threshing productivity than single person, but it is 1.4 times lower than the thresher of the grain harvester.
