The problem Im having is when I do a roast over 300 grams in the BM nowadays Im getting a small percentage of beans, normally around 20 grams worth, which are not roasting past a beige colour (not to FC).
I roasted 300 grams of the Red Sea Blend a few weeks back and it looked good, except when dumped into the cooler a small pile of unroasted (not green) beans landed on top with chaff.
I just did a 560 gram (6 bean blend) roast and exactly the same thing happened. I picked out 20 grams worth of unroasted beans. During this roast however I could see a yellow coloured bean or two do a lap of the BM bowl every now and then. So it was in the direct firing line of the HG yet didnt roast property.
I have done a few smaller roasts, ie 200 grams worth, with no problems.
Cant figure out if its the HG or the BM, however both seem to be working well :-/
Could it be the beans themselves?
