Application of Mechanical Oscillations in Medicinal Plants Sorting Process

摘要

Separators with plane sieves have an oscillating movement and are used for inhomogeneous mixture processing of medicinal plants obtained after chopping. From the analysis of the kinematics and dynamics of the separators and of the oscillating sieves type, results that the medicinal plant material movement, subjected to separation, in relation to sieve surface is influenced by the amplitude and frequency of the oscillations produced by the oscillating mechanisms and the angle of inclination to the horizontal of the separation surface. The paper presents the experimental results regarding the parameters of the sieve oscillations (amplitude and frequency) of a dimensional sorting machine, equipped with oscillating plane sieves. Also, are presented experimental results regarding the effectiveness of unbundling along sieve length of chopped medicinal plants for three oscillation frequency and three sieve inclination angles, for establishing the optimum working parameters, so that a qualitative separation is performed.
