JUSTIFICATION OF PARAMETERS OF ELECTRICAL SUBSTITUTION DIAGRAM FOR CASTORE SEED COMPONENTS

The purpose of the research is to increase the efficiency of hulling castor bean seeds and separating its crushed seeds in the gen-eral technological process of material processing. In the technology of castor bean processing, an important place is occupied by the operation of hulling and separating its crushed beans, which should prevent toxic substances such as ricin, ricinin and allergen from entering the final product of processing. When applying electrophysical methods of influencing castor bean seeds, it is neces-sary to have an understanding of the electrical properties of the components of castor bean seeds, such as the kernel and husk. Knowledge of such properties is necessary for the development of devices that will use electric fields in the technological operations of hulling castor bean seeds and separating its crushed grain. However, since the seeds of agricultural crops are dielectrics, and polarization processes occur in any dielectric, it is not possible to substantiate their electrical properties without understanding these processes in relation to castor bean seeds. Therefore, the purpose of the article is to establish processes in the components of cas-tor bean seeds that occur under the influence of voltage applied to them by substantiating the parameters of the electrical equiva-lent circuit. As a result of the justification, equations were obtained to determine the parameters of the electrical equivalent circuit for the kernel and seeds of castor beans, namely: capacitance due to electronic and ionic polarization, capacitance due to dipole and structural polarization, resistance due to dipole and structural polarization, resistance to through conduction current. Such equa-tions will make it possible in the process of research to establish the electrical properties (dielectric loss tangent, relative dielectric constant and electrical conductivity) of the kernel and husk of castor bean seeds, taking into account the moisture content of the seeds, temperature and frequency of the power supply network.
