Coffee Pellets?

If something new you always pay more
if others follow the price will come down

Hard telling the future. Once there becomes a market for spent grounds, the price might go up. Kinda like with collecting used fryer oil to make biodiesel. It’s great until everyone starts doing it.

I looked up coffee pellets. I see lots of them for sale already, but for pellet grills. Makes sense, being food grade. And like grill pellets, they’re super expensive. Never saw any coffee pellets for downgraded for stove use, with price lowered accordingly.

Yes, I was imprecise.
My main concern would be whether that would make it hard for a "do it at home" log-maker as compared to a pellet press.

I wonder if you could fit the parts to a log splitter. Would 22 tons be enough force? I'm not good at this kind of math.

I don't know anything about making pellets, so I don't know the pressure needed. Commercial machines are not simple cylinders, so calculating the pressure is a tad harder if one doesn't know the inside of the drums.

After that it would be a simple scaling by surface area as pressure is force per (surface) are.

I wonder if you sniff the smoke you get a caffeine hit?

The fumes are toxic and can cause respiratory issues.

So that’s 3000 psi “ideally” for a 3” logon one face. Then spread that out of all the sides. I’m guessing that’s not enough. But I will say my 14 bar espresso machine can make a kinda dense puck a lot of variables.

Would fuel briquette venture be worth it?

Spirilis, I've done a fair amount of research and some prototyping. Here is what I can tell you. To make a briq. with hardwood sawdust, you will need roughly 24,000 psi. With that said, if the end or your briq that you are pressing against is 3x3, then you have 9 sqin. So, you will need...

100 tons???

Hopefully they smell the same as when the coffee guy here in town fires up the bean roaster!

I wish lol… the pellets themselves have a coffee smell but the smoke smells like one would expect… burnt coffee lol… the smell of burnt wood is pleasant , this is more burnt toast-ish lol

How did these pellets work out for you guys?

They worked well during the cold spells for me in my harman 52i… they burn hot for sure. The downside is they do seem to be a bit dirtier than wood but leave very little ash … they are a bit sootier than wood but no odd buildup to speak of .

 

[EatenByLimestone]

Are they noticeably hotter than wood only pellets?

Yes they are very hot burning, it’s a lot less feed cycles to regulate to satisfy the esp sensor on the harman, I go through less overnight so that shows btu content is higher as well

 

[EatenByLimestone]

That’s cool! I was wondering if the hype was real!

 

[vgrund]

I wonder if the exhaust is acidic and requiring special venting (like corn).

unfortunately i am also in CT, where did you get them?

Dean’s stove had them and I believe they still do this year but being as mild as it has been I’m not sure we need the extra btu lol.

awesome, they're right down the road
