abstract:
One of the stages of processing of crumbled or shredded plant materials is earlier separation of components with varied usability. The paper presents a method of separation of crumbled plant materials (rape seeds) through the utilisation of the behaviour of their particles in the electrostatic field. Preliminary investigations were conducted in laboratory conditions, taking into account the degree of crumbling of the seeds and the intensity of the electrostatic field. The method applied allowed to separate particles of the seed coat from crumbled rape seeds, as material with little value for further processing (expression of oil, utilisation of rapeseed meal as fodder for animals). Conducted investigations confirm that the electrostatic field has a diversified effect on loose material of plant origin. The intensity of the influence depends closely on the electric parameters of the given material and on the intensity of the field. The investigations proved that with the growth of the electrostatic field, the effectiveness of separation increases.
