(Page 1) Many chemical processes in the U.S. that use centrifuges were established between the 1950s and the 1980s. As a result, most of these machines employ technology that was outdated literally generations ago. In addition, many processes have changed since installation, and doing more with less is now a key method of survival in today’s global economy.
In centrifuges with a solid wall bowl (Figure 9.9), the liquid phases are discharged continuously but, as in the tubular centrifuge, there is no outlet for the sludge.The accumulated solids are removed manually when the machine is stopped and the bowl is taken apart for cleaning. Such machines are therefore suitable mainly as separators (e.g., for separating cream from skim milk), but cannot ...

A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a force perpendicular to the axis of spin (outward) that can be very strong. The centrifuge works using the sedimentation principle, where the centrifugal acceleration causes denser substances and particles to move outward in the radial direction.
The importance of centrifugation in the pharmaceutical industry has rarely been studied.

A three stage centrifuge especially adapted to the separation of oil, water, and solid particles in an emulsion. As an example, the centrifuge may be used to separate sediment and water from a petroleum product such as crude oil. The three stage centrifuge includes a rotatable bowl that spins the emulsion to separate the fluid oil and water into separate pools within the bowl.
Disc stack centrifuges are common in bioprocessing. There are many types of disc centrifuge; the principal difference between them is the method used to discharge the accumulated solids. In simple disc centrifuges, solids must be removed periodically by hand.
