ABSTRACT:
An ultraviolet (UV) light disinfection method and apparatus is provided that disinfects produce products such as fruits and vegetables by direct exposure to ultraviolet light. The disinfecting UV light eliminates pathogens, such as molds and bacteria from the surfaces that it illuminates. The produce product is disinfected over its entire surface. The produce product can be rotated on a conveyor, to illuminate all of the exterior surface of the produce product with a disinfecting UV light source. To better respond to produce products of varying height and size, the UV light disinfection apparatus can include an automatic actuator. The automatic actuator maintains the UV light source at a preselected level of separation between the produce product and the UV light source. The automatic actuator is responsive to a height sensor that detects the top height of the produce product.
