Centrifuge
- A rotating vessel in which solids are separate from liquids, or liquids are separated from density.
HISTORY
In 1864, Antonin Prandtl proposed the idea of a dairy centrifuge to separate cream from milk. The idea was subsequently put into practice by his brother, Alexander Prandtl, who made improvements to his brother's design, and exhibited a working butterfat extraction machine in 1875.
