Acoustic cleaning
Acoustic cleaning is a maintenance method used in material-handling and storage systems that handle bulk granular or particulate materials, such as grain elevators, to remove the buildup of material on surfaces. An acoustic cleaning apparatus, usually built into the material-handling equipment, works by generating powerful, audible sound waves which shake particulates loose from surfaces, reducing the need for manual cleaning. Higher frequency sound waves are used in Ultrasonic and Megasonic cleaning
