Abstract
Abstract The theoretical study made it possible to define the main correlation dependences affecting the efficiency of grain preparation for milling. Experimental studies allowed improving the technology of grain softening and washing. Design and operating parameters of ultrasonic facility and technology ensuring high degree of grain cleaning and moistening were studied and structured, namely: ultrasound frequency – 18 kHz; process temperature – 30-40 °C; processing time – 30-40 s; intensity of ultrasonic waves – 1 W/cm2.
