As in the creamery and the cheese factory, the milk is carefully examined and, if it is not sweet and pure, it is rejected and sent back to the farm. Any impure flavor remains in the cover for some time and is easily detected by smelling of the cover as soon as it is removed from the can.

A sample is taken and put aside for the Babcock test and perhaps another for the Fermentation test. Each farmer's milk is weighed in the Weigh Can and run through a cheese-cloth strainer. The further treatment varies in different plants. The milk may simply be cooled by running it over a cold water or brine cooler and placing it in shipping cans in the refrigerator or in ice water until the milk-train comes along to pick up the cans. Or it may be clarified by running it through a centrifugal machine, the same as a separator, in which, however, cream and milk are not separated, but impurities are thrown out by the centrifugal force and deposited on the wall of the bowl, and the purified
