Abstract

The objective of this paper is to study the feasibility of using locally made threshing machine for dry bean( Giaz 6 seed) and selecting the optimum conditions for operation. Threshing drum speeds tested were 11.72 , 13.18 and 15.38 m/sec., feed rates 10, 15 and 20 kg /min and seed was used at moisture contents of 13.56, 11.53 and  9.20 % . The obtained results show that, the local threshing machine can be successfully used for threshing bean under the following conditions :  seed moisture content 9.20 % drum speed 15.38  m / sec and feed rate 20 kg /min, resulting in seed damage of 2.17 % and un-threshed  seed of 1.48 %  ,threshing efficiency of 98.52 % , consumed power 14.70 kW and  criterion cost of 143.20 L.E /ton including  operation and losses.
