Abstract
A tank washer such as for use in washing bulk milk tanks, including a liquid-driven spray head rotatably carried on a supply tube extending downwardly into the tank. The spray head is caused to rotate at a relatively low speed, permitting generally square jet streams of the washing liquid to develop a spray pattern effectively completely wetting the interior of the tank to provide effectively optimum washing action. The spray head includes a drain port for draining the apparatus upon termination of the washing liquid delivery. The spray head may be formed of a plurality of similar annular elements and securing structure for securing the elements in a tubular assembly adapted to be rotated coaxially about the delivery tube by reaction force generated by the jet streams. The annular elements cooperatively define the jet ports and include deflector shoulders for directing a portion of the jet streams angularly upwardly.
