| Abstract | ||||
| The aim of this work is to test the feasibility of using El-Shams rice thresher as a dual purpose machine to obtain seeds and stalks from flax crop. The thrshing was performed by using a range of drum speeds, feed crop rates and the lengths of conveyor chain tension at four different levels of capsule moisture contents. Results of the experiments indicated that, for optimum perormance, the threshing drum speed, feed rate and the length of conveyer tension should be about threhing drum speed, feed rate and the length of conveyer tension should be about 31.43m/s., 20kg/min and 48 mm. respectively at 18.45% moisture content of capsules. The highest stripping efficiency, threshing efficiency and cleaning efficiency were 99.6 99.2 and 95 to 98 % respectively. At the same time, the seed damage has noeconomical importance, at the -obtained value of 1.78 %. The optimum fuel consumption values were 3.70 L/h and 3.08 Uton at 31.43 m/s drum speed and 20 Kg/min. feedrate. the average cost of flax threshing was 16.23 L.E/ton compared with SO L.E/ton for manual threshing. | ||||
