Inconsistency problems
BeefTips
I recently finished my BM build and have done a few roast. So far I'm loving it! I love the process and the coffee has been way better than what I expected. I'm just curious as to how to get a more even roast. I have some beans that look more full city plus and some a good city. I've been roast 1lb at a time. Don't know if I need to back down the size of my roast. I have good agitation I think. I have the HG 3-4 inches above the beans with it in the lid of the BM. Any suggestions. Would adding a exhaust help?

Here is my profile, the batch, and a close up of the problem.

Agitation is very important
If your BM paddle shape is not mixing thoroughly it will create hot spots at the heating point

Or you may have a hot spot from the Heat Gun
Try a diffuser

Then again some ungraded beans of different size in the same batch will roast at different rates

How can I test see if it's my paddle?

The only diffusers that come with the hg are smaller than the original. Would that help?

How can I prevent that beam problem? Is it a source issue or an origin or something else?

Thanks for the help.

1) Place 3 to 5 coloured beans in the BM with your regular amount you roast and observe the mixing (use nail polish )


2) Anything to break / diffuse the straight line to the bean mass

3) Can?t do anything about bean processing and grading ? move on and try other beans
Although you can spritz the green beans with water ( 1 or 2 trigger sprays ) as it may help to even out the moisture levels
