What distinguishes agitated drum reactors from static drum reactors based on the text?
What distinguishes agitated drum reactors from static drum reactors based on the text?
- Agitated drum reactors use continuous agitation, while static drum reactors use sporadic agitation
- Agitated drum reactors are used for biofuels production, while static drum reactors are used for aroma compounds production
- Agitated drum reactors are built in drum-shaped, while static drum reactors use a horizontal cylindrical vessel with a worm inside
- Agitated drum reactors do not contain baffles inside, while static drum reactors contain baffles (correct)
What is the advantage of laboratory-scale bioreactors mentioned in the text?
What is the advantage of laboratory-scale bioreactors mentioned in the text?
- They are based on manual monitoring of important process variables (correct)
- They are relatively gentle and provide uniform mixing by improving baffle design
- They offer forced aeration and agitation for better mixing
- They are used for the production of aroma compounds in a 3kg drum bioreactor
