An apparatus for treating product, such as foodstuffs, has the product delivered to the surface of a rotating conveyor element. Without limitation, one form of the invention has a base that presents a generally planar top or upper surface, with a circular perimeter. This may take the form of a circular shaped table. Most preferably, the rotary table is made of glass or other transparent material. The rotary table conveys the foodstuffs within the field of one or more pulsed UV lights optionally arranged about the table to allow for exposure of the product to the light source. In one form, the light exposure is not only on the top surface, but also from the bottom or below the table.
