The present invention has been derived from the ubiquitous automatic hand dryer, but including also a spraying system to sanitize the dried hands. The hollow spraying & drying chamber with hundreds ventilator outlets and multiple spray nozzles functions as a closed-loop, air-recycling system: The drying air is pressed towards the surface of the inserted hands in a down-stream angle； this downstream being enforced by the ventilator aspirating the air from the bottom outlet of the spraying & drying chamber. In contrast to the ubiquitous automatic hand dryer, the casing is closed, completely on the side walls and leaving only small openings at the higher-end side, large enough to insert the hands and suck-in air from above. With this closed chamber and the air-stream from outside above downward along the hand's surface, any emission of air-water droplets as aerosols, upward and to the environment, against the incoming air-stream, is impossible.
