In Rob's case, I don't think so. He is concerned with inlet temperature not being excessive and manages that with high airflow to distribute heat through the roasting chamber. In my fluid bed roaster, I don't do a maximum load so that the air will freely circulate through the bean mass. With my 1 Kg drum roaster, I have

I know his work and even got that pdf some time ago. I can see someone using 100% air when he roasts a smaller batch size and for my unit too that seems to work better, but if I fill it to max or almost max the lower air setting works better. The reason behind Rob and Rao and

You might also set the air flow at maximum so that roasting temperature is spread through the roasting chamber. That's what I've done with a North TJ-067 1 Kg propane roaster. I start with the highest power setting when the beans are most able to absorb heat and bring it back throughout the roast. I think that Rob Hoos in

I did a quick browse on espressoparts.com to see if I could visually match it, but had no luck. I have mostly worked on older machines from the early 90s

Coffee with brand name DeLonghi could be Kimbo (at least it's sold that way in my country together with espresso machines), quite dark roast, and probably something like half a year post roast, it's not expected to produce something tasty

Thanks for the heads up, it seems I cant cancel my initial order for the vacuum breaker anyways so I guess I'll just get both and kill two birds with one stone. Any good how to videos on this?

The original spec sheet here: "Decent Espresso news" All that still applies, though we've added a few things since then (such as a temp sensor for steam auto-stop) Schedule-wise, we will be able to ship 30 beta units at the end of July. We'll have all but 3 of the parts we need two months earlier, but those
