My first drum roaster: where should the beans fall out, bottom or front?
zamunda
Hello,

I am in the process of building my first electric drum roaster, done some testing with several prototypes and I an enthusiastic about the results so far.

Now I have an issue with the drum: I designed a mixer for the drum to move the beans around during roasting but now I would like the beans to fall out by an outlet in the front panel. However, how can all these be pushed outside once the front door is open?
I could make a door at the bottom of the drum since the drum is fixed and the mixer turns around. That way all the beans fall in a drawer or cooling tray.

However, I would prefer the front door solution but do not see how to push 100% of the beans outside once the door is open.

Any ideas/suggestions!

Added a picture of the drum I would like to use as a starting point, it is from a washing machine.
Thanks in advance!

And, to reply to your question, is the vanes design responsible of this dump.
Usually there are two sets of vanes, shaped such way to create two beans flows, front and back along the drum.
When you open the front door, the back to front flow will dump them all, sooner or later, because back is still closed.
