Question

Which of the following disrupts vortex and provides better mixing?

1.Baffles

2.Impeller

3.Sparger

4.Foam breaker​

Answer 1

Answer:

The airlift bioreactors provide better mixing than bubble column reactors.

Answer 2

1) Baffles

In a reactor, during fermentation, oxygen is used and the rate at which it is transferred depends on the stirring method. Some stirring methods create vortices that cause air bubbles within the liquid. The creation of vortices is even higher when the liquid has a low viscosity mainly because low viscous fluids also have a low velocity. Therefore, baffles disrupt the vortices in order to allow a smooth mixing of the fluid.
