Cleansing arrangement for a milking machine

摘要

A cleansing arrangement for a milking machine has a reservoir for cleansing fluid. A vacuum line for conveying the cleansing fluid through the milking machine has an inlet end at the bottom of the reservoir and an outlet end at the top of the reservoir. A metering device for measuring predetermined amounts of concentrated cleansing fluid is located inside the reservoir. A pipe connects the metering with the vacuum line. The pipe has a branch which leads to a supply of water to serve as a diluent for the concentrated cleansing fluid. The metering device is further connected with two sources of different concentrated cleansing fluids via two separate pipes. Each pipe has its own valve member which normally closes the respective pipe. A handle is provided for selectively opening the cleansing fluid supply pipes. In operation, the handle is moved to open one of the cleansing fluid supply pipes. A measured amount of cleansing fluid is drawn into the reservoir via the metering device by means of suction created by the vacuum line. Subsequently, water is admitted into the reservoir to dilute the cleansing fluid and additional water is admitted directly into the vacuum line. The diluted cleansing fluid from the reservoir is drawn into the vacuum line and, after mixing with the water admitted directly into the vacuum line, is conveyed through the milking machine to cleanse the same. The diluted cleansing fluid is then returned to the reservoir where it may be temporarily stored for further use.
