Abstract
The study of the sunflower seed separation process during its movement on the
vibrating surface has been carried out in two stages. The first
(theoretical) stage has been implemented in the software package STAR-CCM +
using the corresponding physical models. The second stage is the conduct of
experimental research on a pilot sample with a base of vibrating pneumatic
PVS table. As a result of numerical simulation and experimental studies of
the sunflower seed separation process during its movement on the vibrating
surface, we have determined the dependences of the change in the
distribution coefficient, productivity and power consumed by the vibrating
pneumatic separator from the seed supply, the inclination angles of the
vibrating surface, the frequency and amplitude of its oscillation and the
velocity of the airflow V. The statistical analysis has shown that the
correlation coefficient between the theoretical and experimental
dependencies in the variation of the values of the factors in the given
range is 0.88-0.92. The technological and constructive scheme of the
adaptive vibrating pneumatic separator with rationally defined regime
parameters (seed supply, airflow velocity, deck oscillation frequency, deck
inclination angle) has been developed basing of the obtained theoretical and
experimental dependencies, using the software which is based on the created
algorithm, allowing to perform the technological process of sunflower seed
mixtures separating by volume density with higher productivity and quality.
