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? |

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 KK I home roast and I like it.

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. |

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 KK I home roast and I like it.
