By means of a series of roller brushers the citrus is conveyed under a foam applicator where with the help of a solution of biodegradable detergent and water, ensure the disinfection of decaying spots or eventual harvesting surface wounds. Between the applicator and the rinsing hood is the washing and scrubbing area where rotating brushers displaces excess of solution as well any residual dirt. Then, the clean fruit moves forward reaching the waxing section where a nozzle uniformly sprinkles a water soluble wax. To fix the protective wax film, the citrus is automatically conveyed to the section where a gradual drying process take place.
