<p>Thanks for the reply.</p>
<p>A couple of questions:</p>
<p>How old is your IR12 and do you have a cyclone on it?</p>
<p>If not, how does the IR12 remove the exhaust smoke? Is there a dedicated fan connected to the exhaust pipe?</p>
<p><span>How are you able to roast manually? Diedrich says that you cannot override the automation.</span></p>
<p></p>
<p></p>

<p>I worked for about 6 months on a Diedrich IR-24 (no longer made.) The chaff collection is handled with a baffle setup below the cooling tray - definitely not as effective as the cyclone behind a Probat in my previous roasting job. It allowed more chaff to pass through to the exhaust pipes and it filled/clogged more quickly (the people we bought it from said they emptied it after every 2-3 batches!) Can't say if the baffle system is better or worse on the IR-12.</p>

<p>As for the second part of your Diedrich question, could you clarify? Not sure what you mean about exhaust permeating the beans. The airflow through our Diedrich was conceptually the same as other drum roasters I know, so I'm not sure what exhaust issue you're talking about.</p>

<p>I've never roasted on a Primo, but the only one I've seen with my own eyes had a bizarre temperature control system that I didn't like the looks of. Rather than manually controlling heat input (amount of gas burning) it had you set a temperature on a digital display and it would cycle the heat on and off to hit that temperature. Judging from the internal plumbing and valves, it appeared to be all or nothing on gas flow, sort of like the way your furnace at home is all-on or all-off, cycling periodically to keep your house as close as possible to the target temperature. If I'm right about how it worked, it would be an absolutely miserable way to control a roaster. Ever since I saw the guts of this thing, I've wanted to know more. I may have been misinterpreting what I saw, so if anyone reading this comment can clarify, please do!</p>
