Розроблені математичні моделі і отримано аналітичні залежності для розрахунку режимних
параметрів процесу охолодження зерна у вібропневмовідцентровому апараті. The purpose of research – create a mathematical description of the thermal and mechanical processes during cooling of the grain material pneumovibrocentrifugal layer.
Dimensional mathematical model describing the thermal processes in the cross-flow grain and the air
has been developed. The analysis which made it possible to obtain a differential equation of grain cooling
dynamics and the formula for calculating the change in the temperature of grain in time.
By analyzing the movement of a point on the inner surface of a rotating cylindrical sieve, which
performs vertical harmonic oscillations were obtained image velocity depending on the flow of grain from the
airflow and rotation frequency of the sieve.
As a result of theoretical investigations established simplified mathematical model of grain cooling
processes in rolling vibrocentrifugal layer when exposed to air cross flow. These formulas and graphics that
allow you to define the parameters of thermal and kinematic modes of operation of the cooling unit.
