move quickly or slowly, according to their weight and shape., towards the 

 channels n at the periphery of the plates. Perfectly round seeds roll quickly 

 off the plate and reach the annular channel on the first carrier platform p

 which are gnawed by worms roll slowly to the edge of the plate and only

 the rotary brushes m.
