Device for sanitizing banknotes comprising: - a container where are defined an inlet for inserting at least one banknote into the container and an outlet for extracting at least one banknote from the container; - a first conveyor system arranged in the container and configured to convey at least one banknote according to a forward direction from the inlet to a predetermined area between the inlet and the outlet picking said at least one banknote at a first zone of said at least one banknote; wherein the first conveyor system comprises at least one first conveyor belt located adjacent to the inlet and at least one second conveyor belt, or a plurality of revolving elements, arranged above said at least one first conveyor belt of the first conveyor system such that, in use, said at least one banknote introduced into the inlet is conveyed between said at least one first conveyor belt and said at least one second conveyor belt, or said plurality of revolving elements, of the first conveyor system; - a second conveyor system arranged in the container and configured to convey said at least one banknote from said predetermined area to the outlet picking said at least one banknote at a second zone of said at least one banknote, wherein said second zone is other than said first zone; wherein the second conveyor system comprises at least one first conveyor belt arranged between said at least one first conveyor belt of the first conveyor system and the outlet in a horizontally staggered way, according to a direction transversal to the forward direction, with respect to said at least one first conveyor belt of the first conveyor system; wherein the second conveyor system comprises at least one second conveyor belt, or a plurality of revolving elements, arranged above said at least one first conveyor belt of the second conveyor system such that, in use, said at least one banknote is conveyed between said at least one first conveyor belt and said at least one second conveyor belt, or said plurality of revolving elements, of the second conveyor system; - at least one first UVC ray emitter, or at least one first ozone lamp, arranged in the container in such a way as to directly irradiate and sanitize, in use, the entire lower face of at least one banknote conveyed from the inlet to the outlet by the first conveyor system and the second conveyor system; and - at least one second UVC ray emitter, or at least one second ozone lamp, arranged in the container in such a way as to directly irradiate and sanitize, in use, the entire upper face of at least one banknote conveyed from the inlet to the outlet by the first conveyor system and the second conveyor system. - a container where are defined an inlet for inserting at least one banknote into the container and an outlet for extracting at least one banknote from the container;
