Abstract
A system for backflushing milking machinery comprises a backflush valve for alternatively connecting one or a plurality of milking units to a wash line or to a vacuum milk line. When the milking units are connected to the wash line, a manifold valve operated by high pressure air under automatic control, sends water, sanitizing fluid and air sequentially through the milking units. Provision is made for sending bursts of air through the water and sanitizing liquid as they are furnished to the milk units. Provision is also made for flushing the back-flush valve with water after a washing cycle to prevent entry of washing fluids into the milk line.
