Want to talk espresso but not sure which forum? If so, this is the right one.

Hi

We have been thinking of ideas of how to build an effective chaff collector, does any one here know how the commercial chaff collectors are built or have any idea as to how a chaff collector should be built?

Thanks

Look up cyclones for sawdust. Same principal.

The metal Dust Deputy will work just fine.

I have a cyclone collector on my roaster. Works pretty good.

Hi

So after a bit of research i am still confused as to how a cyclone works :(

I found this on ebay
http://www.ebay.com/itm/Cyclone-Dust-Se ... 1792844537

But not sure what goes into each inlet, in order to simplify things i have named each inlet as A B and C.

The image above has them labelled

So i was really hoping if someone could correct me if i am wrong.

Coffee chaff goes into the cyclone through inlet A.

Inlet B is connected to a motor or is a motor that blows air downwards.

Inlet C is where the coffee chaff passes through into a bucket and gets collected.

Now one very important question, what happens to the hot air that gets blown from the coffee roaster, where exactly does that go?

Would really appreciate some insight.

Thank you

Any hot air will be sucked out inlet B with hopefully some cooling from the vent pipe and the cyclone to prevent any damage to your blower.

Hi Yakster,

Thank you for the reply, so does pipe B have to be connected to a fan or a blower blowing air downwards?

No, you want to draw the air out so you could pull air from the roaster through the cyclone with a fan or blower drawing air out or you could have a fan before the cyclone (I think) pushing the air through it but it would probably work best with a fan drawing air through the cyclone and out port B.

As a maker who has more time and research into dust collection systems than I care to admit, the best performing cyclone you can buy on the market today is the oneida systems dust deputy. Of course it's pretty big but if you're thinking about building a chaff collection system, you might want to base it on that design.

If you want to go really DIY, you can try a modified woodcraft dust collection lid (for a 5gal bucket, $20). Add an extra elbow joint on the underside and point it away from the outlet and it will performed almost as good as the dust deputy, and has a far lower profile.
You're not always right, but when you're right, you're right, right?
