Vacuum systems for getting rid of spent biomass

moving biomass by making it into a water slurry was helpful when I first started doing cryo-ethanol in beer kegs (unmodified) . I didn’t bother unpacking the first one till I ran out of kegs. Once I proved they could be emptied with a garden hose I handed the task off to a minion.

Not as relevant to emptying the centrifuge as a 500gal reactor.
there might be more appropriate centrifuges…
