The invention discloses a yak meat multilayer air-drying device. According to the scheme, the yak meat multilayer air-drying device comprises an air duct, one end of which is communicated with an air-inducing device and the other end of which is communicated with an air-exhausting device; two ends of the air duct are respectively provided with an air-inlet separator plate and an air-exhausting separator plate; baffle plates are vertically and uniformly arranged between the air-inlet separator plate and the air-exhausting separator plate; the lower surface of each baffle plate is provided with a hook; the top surface inside the air duct is equipped with hooks; the air-inlet separator plate and the air-exhausting separator plate are vertically and uniformly provided with through-holes; and each through-hole is positioned between two baffle plates. The invention aims to provide a yak meat multilayer air-drying device. By arranging a layered device inside the air duct, airflow in the air duct can all flow to beef. Thus, utilization efficiency of airflow is raised.
