Application of ultrasound to enhance the separation of cereals
Vedmedenko N.S., Palchikov A.N., Antufiev V.T.
The work proposed and studied the technology of separation of cereals in the tribe electrostatic separator with the physical effects of ultrasound. Theoretical and experimental studies have confirmed the effectiveness of this method. The research work aims to explore changes in the process of separation of grain products by adjusting the parameters of the ultrasonic transducer, which greatly affect not only the uniformity of expiration of their feeder with an increase in productivity, but also on the value of the electrostatic charging of cereals, which can significantly improve the triboelectrostatic separator. Ultrasonic hopper-feeder provides a stable supply of bulk materials and their electrostatic separation of fractions with minimal specific energy consumption. The results of the experiment, indicating the possibility of application of ultrasound to enhance the separation of grains.
