A kind of Chinese herbal medicine automatic ultrasonic cleaning and sorting device and Chinese herbal medicine cleaning process

Abstract

The invention provides an automatic ultrasonic Chinese herbal medicine cleaning and sorting device which comprises a cleaning chamber (1), a shear flow generating mechanism (10) and an ultrasonic vibration mechanism (30). The shear flow generating mechanism (10) comprises an inner rotating roller (11) and an outer rotating cylinder (12) which are opposite in rotating direction. A ring-shaped spacebetween the inner rotating roller (11) and the outer rotating cylinder (12) is a shear flow space (17). The lower end of a guide-in channel (2) is connected to the top of the shear flow space (17). The ultrasonic vibration mechanism (30) is fixedly arranged above the shear flow generating mechanism (10). The ultrasonic vibration mechanism (30) comprises a vibrating head (35) which is inserted into the top of the shear flow space (17). Ultrasonic waves sent by the vibrating head (35) penetrate into from the top of the shear flow space, and penetrate out from the bottom of the shear flow space(17). Chinese herbal medicine roots (5) are impacted by the ultrasonic waves from top to bottom along a rotating in the rotating direction while being shorn by water flow of the shear flow space in the cutting direction of the rotating direction. According to the automatic ultrasonic Chinese herbal medicine cleaning and sorting device, the plant roots are not damaged, and the cleaning rate of theChinese herbal medicine roots can reach over 99%.
