Process (also sewage centrifuging, separation) in which certain particles are removed from a liquid by means of mechanical centrifuges (separators) using centrifugal force (centrifugal force). Depending on the type of centrifuge, 4,000 to 6,000 times the force of gravity is generated. In viticulture, stainless steel devices are used, especially in larger operations. The wine or must is pumped into the separator, accelerated to rotational speed and flows upwards through holes in the disc pack. The centrifugal force on the underside of the disc causes the heavy lees to migrate outwards, while the clarified (lighter) wine or must flows inwards.

Systems

Depending on the separation principle or technology, there are chamber separators (closed systems) and self-cleaning disc separators. With chamber separators, the process must be interrupted once the sludge chamber is full and the separator must be opened and emptied. With disc separators, on the other hand, the accumulated sludge is spun off by regularly opening the chamber for a short time and stopping the liquid feed.
