Title: Homemade drum roaster question
Post by: doveguy1 on October 02, 2008, 08:52:03 PM
Has any one used a drum that did not have holes in it? If so how did it work?

Some pro models do it don't they?

I think if you move the drum closer to the flame and bump the RPM's it would sure be worth a try at least.

Inquiring minds want to know...

I've been gathering bits and pieces to build one and was thinking of using some 8" stove pipe and caps for the drum.

I have not yet tested my theories but I believe a closed drum would work well especially if you could pre-heat the drum before adding the coffee (maybe only to 300 F) I bet Hananon can answer this for sure but I suspect the roast time is longer since the drum has to heat up before the beans.  My small mesh behmor drum is as close to the heat as it can get and the drill I use is a little fast but the roasts are pretty good so I gave up on my wild dreams of a ceramic drum (for now)   ::)

My shot in the dark answer is to consider the drum thickness/material and the potential heat sink it will be.  A solid drum can work fine, but if it holds a ton of heat it will be unresponsive. 

Good time to reintroduce my own acronym; AIIKWITA  As If I Know What I'm Talking About   ;D
