Abstract

A roller flax deseeder was designed, constructed and tested to evaluate its ability to deseed flax without causing  appreciable stalk damage. The deseeder was tested and evaluated at El-Gemmiza Agricultural Research Station, El-Gharbia  Governorate under four revolving speeds for upper rollers (2.93 , 4.69 ,6.45 and 8.21 m/s),three revolving speeds for lower rollers(0.67, 0.97, and 1.2 m/s)and three clearance between upper and lower rollers(1.5,2.5 and 3.5 cm). Machine productivity, stalk losses, power requirements and deseeding efficiency had been determined. Optimum values for the operation conditions were obtained at lower rollers speed of 0.97 m/s and upper roller speeds of 8.21m/s (kinematics parameter of 8.46) and clearance between lower and upper rollers of 2.5 cm. Where as given the best results of deseeding efficiency (99.65 %). Regarding the effect of threshing system on criterion costs, results show that the rubbing deseeder system recorded the minimum values of criterion costs (82.72 L.E/ton) comparing with the other threshing systems (205.67 and 254.08 L.E/ton) for traditional method and impact thresher respectively.
