Abstract: In order to solve the problems of large area, low degree of automation and strong manual labor of the cleaning device in the deep processing industry of Hermetia illucens, a design of the control system for the automatic cleaning device of Hermetia illucens is proposed in this paper. The system consists of single chip microcomputer, liquid level sensor, man-machine interface, ultrasonic vibration module and Bluetooth transmission module.The single-chip microcomputer is used as the control core, and the control mode of serial port screen and Bluetooth APP is adopted to automatically complete a cleaning action including water circulation, loading and unloading, and cleaning, and cycle the cleaning operation before pressing the stop button. The experimental results showed that the cleaning effect of the system prototype was the best when the cleaning time was 12 minutes when 50 g of Hermetia illucens was cleaned. It realizes the automation and visualization of the cleaning process, reduces the labor intensity of the staff, and greatly improves the cleaning efficiency of Hermetia illucens.
