Abstract
Abstract An automatic washing and sanitizing apparatus for a pipeline milking system. The apparatus includes a 24 hour timer to automatically start and program the sanitizing operation prior to milking so that the completion of the sanitizing cycle the lines have been drained and the system is ready for milking. After the milking, the washing cycle is initiated and the apparatus automatically programs a first rinse cycle, a wash cycle, and a second rinse cycle with detergent and acid being automatically dispensed into the water during the wash and the second rinse cycle, respectively. A fail safe mechanism is incorporated in the system which will automatcially deenergize the system in the event of a malfunction.
