A broadcasting processing apparatus and a control method thereof are provided. A first fin structure and a second fin structure are spaced at a distance D1. An ultraviolet light permeable conveyor is configured to move the product through the interior space from the inlet to the outlet. A first lip extends from the distal end of the wall portion by a first extent in a direction non-orthogonal to the base, the first lip defining a first perimetrical sealing surface.
