Abstract
Cleaning air knife elements are assembled in a parallel orientation inside a housing enclosing the air knife assembly and in fluid communication with a compressed air source. In certain embodiments, the air knife elements are spaced apart a distance that orients the cleaning air knife discharge slots directly parallel and in line with the slots of the air nozzle or bar to be cleaned. Air discharging from the air knife discharge slots passes through the discharge slots of the air nozzle to be cleaned, dislodging dust and friable solid buildup from the air nozzle slots. Additionally, the cleaning air jet enters the air nozzle body, further dislodging dust and friable solids from the internal passages of the air nozzle inside the air nozzle body.
