Definition of centrifuge in English:



  • A machine with a rapidly rotating container that applies centrifugal force to its contents, typically to separate fluids of different densities (e.g. cream from milk) or liquids from solids.

    • ‘Use of filters and centrifuges to eliminate all solid matter are effective, but some people claim these methods also remove body and character from the wine.’
    • ‘Next, the crystals are harvested from the refining liquid through two centrifuges arranged in parallel.’
    • ‘After donation, all the blood is divided into its constituent parts by a 3,000-revolution per minute centrifuge according to differential density.’
    • ‘If a passenger candidate develops electrocardiographic abnormalities during centrifugation, the centrifuge can be stopped and, most likely, the irregular heart rhythm will revert to normal beating.’
    • ‘In addition, he informed the Agency that the commercial scale enrichment facility, which is planned to contain over 50,000 centrifuges, was not scheduled to receive nuclear material in the near future.’
    • ‘Blood was collected from the basilic wing vein, and plasma was separated with a centrifuge.’

    • ‘Sugar from sugar cane - cane is crushed to release its juice which is cleared of impurities, reduced down then spun in a centrifuge to separate the sucrose which is allowed to crystallize.’
    • ‘Employees then apply a series of enzymes to break down the connective tissue between the cells and spin them in a centrifuge to separate the cells from the intercellular waste.’
    • ‘Nowadays cream is separated mechanically in a centrifuge, a revolving circular vessel in which the cream migrates to the centre, from which it is drawn off.’
    • ‘A decanter centrifuge is defined for separating a heavy phase material from a liquid within a feed mixture.’
    • ‘When blood is taken, it is spun in a centrifuge and the platelets separated out, with the remaining blood going back to the donor.’
    • ‘The murky liquid produced is part oil, part fruit water, and it has to be separated in a centrifuge.’
    • ‘The suspension is then passed to a series of centrifuges where the cells are separated from the liquid residue, and these centrifuged cells are collectively known as mycoprotein.’
