Packaging machine with multiple UV lamps transverse to package path

摘要

An ultraviolet sterilization system for a form, fill and seal packaging machine, includes at least three ultraviolet lamps, each having an elongated dimension and a transverse dimension. Each lamp is mounted within a housing having a reflector. The lamps are mounted adjacent one another in a side-by-side manner such that the elongated dimensions are parallel to one another and transverse to the package conveyance path. The ultraviolet sterilization system, in conjunction with a hydrogen peroxide application at a concentration of about 3.0 percent, provides a log reduction of at least about 4.5 to 5.0 of microbial colony forming units.
