Vacuum systems for getting rid of spent biomass

[cyclopath]

The biggest difference between your hammer milled biomass and the woodworking waste that you’re comparing it to would seem to be the residual solvent and it’s flamability. Sure, wood dust is problematic, but Ethanol vapour above its flash point seems like a much bigger problem. The solvent also adds weight and a degree of cohesion to the material that is absent in wood working waste.

I’m using material post CUP as my metric here, and the NSEP spins quite a bit harder.

any chance you could share your milling solution over here?

Biomass Grinding at various scales?

Looking for recommendations on a pre-process biomass grinding options. Passing through a 1/4" screen after freezing at -80C is my gold standard for particle size, and nothing else I’ve tried comes close. I know some folks use ninjas, but imo a rapidly spinning blade is not the right response. The fines those create just make filtration of solvent from biomass harder to manage. I tried a futurolla shredder they were using next door for pre-rolls, and it wasn’t as bad as I thought it might be.…

Edit: they’re a little out of the way, but mbar might be able to address the feasibility & build out cost associated with a vacuum based spent biomass handling system. I’ve known the owner for almost 50 years, and will pose the problem to them via email…even though none of us are likely to import a system from New Zealand.
