The sanitary trap is where the vacuum and liquid systems meet. The main vacuum line from the vacuum pump supplies the sanitary trap and from it leaves pipes that go to the pulsation chambers in the clusters and receiver vessel of the milk system. A ball is present so that if the sanitary trap inadvertently fills up with milk, the ball floats to the top and closes off the vacuum supply. This is to try and prevent any milk reaching the vacuum pump. The sanitary trap is usually clear and located in the parlour so the operator can see if it is filling up with milk which puts the whole plant at risk of failure if the milk reaches the pulsation or main vacuum system.
