Definition
rate process profile at which imposed motion is applied to agitate a material
Explanatory Notes
Agitation rate is the rate of imposed mechanical motion used to stir, mix, shake, rock, or otherwise agitate a material. It should be distinguished from the resulting degree of mixing, gas transfer, bubble size distribution, mass transfer performance, or product yield, which may be affected by agitation rate but are not themselves agitation rates. Depending on the agitation mechanism, agitation rate may be expressed in revolutions per minute, cycles per minute, hertz, strokes per minute, or another unit appropriate to the motion.
Examples
- an agitation rate of 500 revolutions per minute applied by an impeller in a stirred gas-fermentation vessel; an agitation rate of 120 revolutions per minute applied by a stir bar during buffer preparation; an agitation rate of 30 rocking cycles per minute applied by a rocking bioreactor platform; an agitation rate of 180 shaking cycles per minute applied by an orbital shaker during flask cultivation;
