design of a fermentor - Coggle Diagram
design of a fermentor
aeration and agitation
agitator (= impeller)
disc turbine (radial flow)
vaned disc turbine (radial flow)
variable pitch open turbine (axial flow)
propeller (axial flow)
stirrer bearings and seals
baffle
prevent vortex formation
and improve aeration efficiency
aeration system
porous
orifice
nozzle
body construction
(that can withstand repeated steam sterilization)
small scale
glass
extra heat added
pilot-scale and industrial scale
stainless steel
cooling (because of heat of mechanical agitation)
joint seals (aseptic)
aseptic operation and containment
risk assessment
GILSP = good industrial large-scale practices
low individual and community risk
protect against contamination
axenic (asceptisch maar je laat één organisme toe)
aseptic sampling
sterilization of air supply
heat (expensive)
filtration
valves
control flow
suited for aseptic conditions?
steam traps
remove steam condensate
fermentation vessels
brewing
--> tower fermentor
--> cylindro-conical vessel
