Apparatus and method for all-around dry disinfection

摘要

A dry disinfection unit 10 comprises a housing 11 enclosing a chamber 12, a source of ultraviolet (UV) light 14 emitting ultraviolet light positioned within the chamber 12, a coating 15 applied to at least one surface within the chamber 12 wherein the coating 15 includes a nanoparticulate photocatalyst that is activated by the ultraviolet light, and a UV-transparent support 17 positioned within the chamber 12 to support an object 19 which is to be sterilised. The object is exposed all round to the ultraviolet light and to the activated nanoparticulate photocatalyst. The photocatalyst coating may be applied to the internal walls of the chamber, the UV transparent support or the ultraviolet light source. The photocatalyst may be titanium dioxide. The transparent support may be stationary or may comprises a conveyer belt for moving the object through the unit (fig 3).
