Hi all, Ok , manufactured a new mixer which seems better. 3/8 isnstead of 1/2 inch . allows the whisk arms lower and straighter in the bowl. I just cant hear the cracks ? I stand over the turbo oven staring into it, head almost pressed to the glass but nothing really alerts me to the cracking. I hear the occasional bean being scraped and flung around the chamber? Last roast, yesterday, was 580g. thermocouple in base of chamber under bean mass, temp peaked about 140' c ? 22 min 50 roast time and then thought Id best tip it out to cooler. most beans are brown, some dark brown and some very light. I added four bean varietys at once. Next time I think I will roast each family seperately. But its the cracking thats got me stressed. Do I need to know when it happens or just look for the colour of the bean as the indicator when to stop? I set up my laptop to record the temp/profile, it restarted for some stupid windows update right at the end :-( not going so well. Help.. Oh I also cut out some holes in the heat sheild of the TO as seen on the site.
