I have a $2700 Pawlin modified Computer Controlled HotTop, a $13,000 USRC 3k
with PLC profile control and I'm jealous.
:)

Congratulations! Great first look report.

Ultimately the quest for Koffee Nirvana is a solitary path. To know I must
first not know. And in knowing know I know not. Each Personal enlightenment
found exploring the many divergent foot steps of Those who have gone before.

> The QM3 arrived today. THANK YOU Sweet Maria's and Coffee Shrub!
> 
> The Q is a dream machine, like driving an Italian sports car. 
> Built like a
> tank out of pure highly polished stainless steel, it has a 
> charming look,
> certainly a conversation piece. If it had a couple of brass 
> bobbles and an
> emblem, this thing would look classy. Still, anybody who 
> walked into you
> kitchen would immediately be intrigued by it.
> I roasted three 125g batches back to back and she performed 
> like a champ.
> Cracks are easy to hear. Tomorrow I'll try 250g batches. 
> Finally, I, yo,
> moi, was in control and not a Procrustean bed profile I 
> didn't create that
> blindly executes itself (no, I'm not a control freak no 
> matter what my ex
> says). The back-to-back roasting is easy because the drum 
> stays hot during
> cooling. I'll probably do at least 2 or 3 roasts each session 
> because the
> preheat does take about 15 min.
> The Q is as powerful as she is pretty. I had no problem 
> getting the 125g
> charge up to 2C with a nice 3-4 min. pause between 1C and 2C.
> 
> Here's the big advantages:
> 1. Plenty of heat at your full control. And this isn't on/off 
> cycles of a
> heating element, but steady heat delivered by two heating 
> elements. Set it
> at 7amps and the elements draw 7amps, not on,off,on,off. You 
> can control
> things on the fly. But this requires constant hand-holding. I 
> don't think
> I'll stray out of the room with the Q running. It requires 
> front burner
> attention mode.
> 2. A powerful fan to ventilate the drum chamber and draw out 
> chaff. This
> allows you to control temp. I think Tom said he sets the temp 
> at a good
> steady setting and leaves it there, and then uses the fan to control
> temperature. I'm still learning.
> 3. A trier.Yes, a TRIER,  on a home roaster! Twist it and 
> pull out 4-6 beans
> at any point in the roast. Bite'm, sniff'm. Target your 
> roasts where you
> want them. Careful, that thing is hot! Aside from Whirley pop 
> and HG/DB
> roasting, grabbing a bean out of the roasting bean mass is rare.
> 4. A chamber window. A small window also allows you to see 
> inside the drum
> and look at the beans as they churn. This is like seeing the 
> beans in the
> IR2 chamber dance around. The Q's window is tiny, but it works.
> 5. A Bean Mass temp. probe. The thermometer screws in the 
> front and goes
> right into the rotating mass of beans. I do not like the Celsius
> calibration, but I will learn to live with it.
> 6. A machined and threaded hole is provided for at ET 
> (environment probe) to
> track drum air temp. That temp responds quickly to fan 
> settings. I used my
> thermocouple and digital unit in that hole, but it needs a 
> bushing to hold
> it. [Anybody know where I can get one?]
> 7. Bean cooling is very fast, outside the drum like HT. Dump 
> the beans in a
> tray, place the tray on the back fan box, and the beans are 
> cooled in 2 min.
> flat. It will take longer for 250g charges.
> 8. Chaff control is nice compared to the B1600. After three 
> roasts, the
> chaff collector was still working fine, easy to dump.
> 9. Quiet. Very quiet. I didn't know it started when I turned 
> the timer knob.
> Drum is quiet, fans too. The loudest noise you will hear is the beans
> themselves gently tossing around in the drum, and their 
> cracks. SuuWeeeet!
> 
> Here's the disadvantages:
> 1. It doesn't roast a full pound like the B1600. Perhaps the 
> Q should be
> compared to the Gene Cafe or the HT here. Oh well, as long as 
> she does back
> to back 250g charges, who cares. Some have roasted 300g. 
> Maybe I'll try that
> soon. I believe it has the power. I roasted my 125g batches 
> with 7amps or
> less, and it will use up to 10amps.
> 2. Cost. At 4X the cost of the B1600, it's steep. But I'm 
> pretty convinced
> on first blush, that the QM3 is worth every penny, IF it 
> proves durable.
> 3. No smoke suppression. B1600 is nice on this. But with 
> smaller batches,
> I'm not sure the Q will need it. It is easily small enough to 
> put under an
> oven hood.
> 4. Some don't like the flat exhaust vent on the back. It 
> isn't that big a
> deal, but I roast under a hood. Still, a flat vent like that 
> is easy to
> modify.
> 5. It does get hot! External surfaces will burn you FAST. 
> But, so will my
> cast iron griddle, and my water kettle, etc. It can't be 
> avoided in cooking.
> Just be careful and keep kids away.
> 6. Some think it needs a funnel to dump the beans in the bean 
> chute. Yea, it
> would look cute and be practical, but I poured in three 
> batches and didn't
> spill nary a bean. If even an issue, it is a minor one.
> 7. No UL approval. Significant? Yes, and no.  I'll let others 
> tackle this.
> 
> Bottom line: I highly recommend.
