Backflushing the cluster between cows is a critical step in controlling the spread of such contagious pathogens as Staph. Aureus, Strep. Agalactiae, and Mycoplasma species. Backflush, when used in conjunction with an effective disinfecting agent, can sanitize the milking unit after removal from one cow and before going on the next cow. This can dramatically effect the spread of contagious pathogens being transmitted through the milking machine.
Although backflush has been around for years, it has not been widely adapted everywhere. This is mainly because systems that were sold did not hold up well and the dairyman paid a high price for maintaining and cleaning the system. Once those costs out weighed the benefit, dairymen quit using their systems and many people have not come back to the technology since.
Today, most companies have given up offering backflush systems because of these problems. However, here at BECO our backflush systems are going stronger than ever. That is mainly because we are the one company that has mastered the simplicity and reliability issues making backflushing a useful and economically sound tool like it was originally perceived to be.
After only a few short years following the development of the first systems, BECO admitted that the slide valve concept just wasn't cutting it and further work on that design was not going to change it much. It is a shame that other companies did not follow suit, but rather continued to sell those types of valves and consequently gave backflush a bad reputation. Dairymen that are familiar with BECO have realized that our system is very different and they have successfully implemented the BECO backflush as one of their tools in fighting contagious mastitis.
BECO backflush can be, and is, very simple and reliable. BECO has proven this with hundreds of installations in all size of parlors. Lets face it, if the BECO system can hold up on dairies like Quad D-75 parlors that milk each cow four times a day and still be reliable, you can rest assured it is well tested and proven. By the way.. on just this one dairy in mention that's 80,000 backflushes each and every day!
The illustrations on the right show the inside of the backflush valve. The one on the left shows the valve in the milk position. Looking closely you can see the rubber plunger inside is lifted off of the bottom port of the valve that is connected to the milk line. Upon lifting of this plunger, the valve turns on vacuum to the port on the right side of the valve that is connected to the milking claw. Vacuum is now available to milk the cow.
The valve on the right side shows the valve in the backflush position. Looking closely you can see the rubber plunger is moved to the down position closing off vacuum and the backflush distribution line is now open for the backflush cycle to start.
When this valve is used in conjunction with any of the BECO automatic take-offs, it can also be used as the vacuum shut-off valve and milk sensor as well. Using the BECO Acu-Clean valve like this dramatically cleans up the system making the system ultra simple. No need for multiple valves because milk will pass through just one component before making its way from the claw to the pipeline. One valve with only one moving part...It just doesn't get anymore simple and reliable than that!
