The invention belongs to the field of tea treatment before extraction, and specifically discloses a centrifugal tea dispersing machine. The centrifugal tea dispersing machine comprises a shell, a globular screen mesh, an air pump, and a rotary driving mechanism; the globular screen mesh is located in the shell, and a base of the globular screen mesh is connected to an output end of the rotary driving mechanism; the shell comprises a base, a side wall, and a top cap, wherein the base is rotationally connected onto the side wall, the top cap is mounted on the side wall in a retractable way, and multiple vent holes are arranged on the side wall with the centerlines in parallel; the vent holes comprise first vent holes and second vent holes, wherein the first vent holes and the second vent holes are symmetrically arranged around the centerline of the shell; the distances between the first vent holes are larger than the diameters of the second vent holes; the centerlines of the second vent holes are respectively located between the centerlines of the first vent holes; and the output end of the air pump is connected with the vent holes. The centrifugal tea dispersing machine solves the problems of the prior art, namely large damages on the tea leaves, as well as incapability of ensuring tea quality.
