A centrifuge is a machine that swirls the wine around at a high speed, allowing gravity to separate the heavier particles of the wine, such as the dirt, dead yeast cells, and pulp. Using a centrifuge is one of several ways of filtrating sediment out of a wine. Basically, it's like a washing machine on spin mode, with sediment instead of clothes. Some winemakers swear by the process of centrifugation, claiming that a cleaner wine is a better wine, while many others—particularly in Europe—believe that centrifuging strips the wine of its character and flavor. Because centrifugation is such a fast and efficient means of filtration, lower-quality bulk or "jug" wines are almost always filtered this way.
