Abstract
Screen vibrating is q equipments of winnow of laboring coffee seed mechanically and have some screening level. Hole size measure in every screening adapted for requirement. Principal of screen vibrating to exploit passed to vibration effect screen converged by some spiral spring. Target of this research is design machine of screen vibrating with source of eccentric axis excitation as machine of sorted coffee seed Pursuant to result of examination can be concluded as follows: (1) At same capacities, increase of rotation result degradation of efficiency of screen vibrating (2) Increase of inclination of angle result degradation of efficiency of screen vibrating. (3) At rotation and inclination remain to, increase of capacities result degradation of efficiency of screen vibrating. (4) Optimal performance reached at inclination of angle 10°, eccentric axis rotation 900 rpm, capacities of screen vibrating 300 kg/h with efficiency of screen vibrating 92%.
