Behmor

[Divey]

I'm pretty much new to the Behmor as well and as I store my roasted beans in little Decor plastic tubs that have snap fitting lids which hold about a 117 of green beans that have been roasted. I decided to get a 234 gram roast spot on so I can fill two little Decor tubs.

I went with 234 grams, ½lb, P2 and then deducted 1 minute by pressing the '-' button six times and then start, once the roast started, I added back the minute by pressing the '+' button four times. I did not have to cool before the end of the cycle and I did not have to adjust any further time increments. I did four roasts with four different beans and I was really pleased with three of the roasts, however, I found that one roast with Vanuatu Tanna Island beans where a tad light on and I put half of then back in on a ¼lb roast and watched till the beans took on a further amount of colour and then cooled.

Pretty impressed.

D'oh. I have been calling in my wife to switch it on at the PowerPoint a couple of metres away as I hold down the C button every single roast, week after week since I got it a years ago.

All for no reason it seems.

Hi Divey, glad you're enjoying your roaster.
Just thought I'd mention that the profiles don't work quite the way the paper manual might have you believe, altering the time only affects the final leg. This has been discussed here in the past and there's a huge thread on CoffeeGeek if you're interested in which this was eventually confirmed by Joe Behmor. The manual has been updated to reflect this (at least, the downloadable pdf version has).
The only way to change the first segments is with the A, B, C, D buttons. Google "RoasterThing" for a handy-dandy tool for visualising the roast profiles.

Thanks for that WA.

I had a look at the downloadable pdf version and that whole section ( V 8 )) has vanished.

I have had a look at CoffeeGeek and cant find the relevant section. Can you supply a link please.

Sure. CG Behmor Profile Thread. Or the most pertinent bit here.

Oh, and Roaster Thing. A really, really handy tool IMO. Especially when you've done a roast that didn't work quite as well as you would have liked - hit "duplicate roast" and you'll see a visual representation of the roast profile along with 1C, 2C etc. You can change the program times and get an idea how that might change things...

[Divey]

Wow, there's a fair bit to read there.

That's a bit of a bugger that you can't change those settings as Joe earlier suggested than you can.

I just checked what power I have in my house...... 254.6 volts. Not happy Jan!!

[fg1972]

I've just started using RoasterThing and think it is a great tool. Is really helping me understand the profiles and is a good place to centralize all your information & records.
Is any one using their logging interface?

Followed Andys advice from page 14 for my first roast ever. I got a behmor as a Chrissy present, have never tried roasting before but i was sold on how easy everyone said it was.

India Elephant Hills - 200gm - 1/2 P2 I added 20 seconds at the end prior to cool as i didnt "think" id heard any 2nd crack!! still dont know that i did but Im happy with it! Now to wait and taste it. I don't have a CS card so unsure on what level the roast is....,. Any guesses?

[phrostyboi]

i'd hazard a guess based on the pic at maybe a CS9 - CS10, I don't always get to second crack with my roasts as I like a slightly lighter roast

i'd get yourself a copy of the roasterthing software to keep your notes on as well, I use it myself and find it quite good for comparing roasts and getting some repeatable results

roast looks good for a first one btw too

I have 246-249 in ours, don't worry too much about it, I find that my roasts tend to be shorter than other peoples using the 1P2C setting but still in the range of 13-15 minutes depending on the bean.

[david555]

Having trouble getting a lighter roast on the second crack .I have recently bought be

Behmor 1500 from Andy but am getting the beans close to burnt. Can anyone suggest how to get a lighter roast and the second crack as well?

You'll find the answer to your questions by reading this thread david555.

Hi Guys, got my Behmor a few weeks ago.
Quick question to all (Andy?).

What is the reasoning behind the P2 temperature duty cycle profile - ie dropping the heater duty cycle after about 60% time and then bringing it back to 100% heating for the final stretch?

I roasted 400g of my Elephant Hills AA at a setting of 1lb, P2. Hit the +++ a few times to make sure it didnt end early. When the cycle got to that point where the heater dropps away, the internal temperature (as measured with the multimeter and PC SW) dropped a little, and kept dropping slowly. 1C was heard even when the temp was dropping. I stopped just as I heard 2C..Final product was a very light roast which I did not like and threw away after a few days.

Next day i did a 200g roast on P2. and noticed that the element duty cycle dropped away (as before), temp levelled or dropped a little (as before), but then the elements kicked back in again and the final burst to 1C and 2C was completed with full heater and an increasing temperature...so would indicate my 400g roast never got that final burst at 100% heater duty cycle (I nerver saw it). Tasted much better - like it should...

Does this sound like a mismatch of bean mass to profile selection?? ie 400g a bit too light for the 1lb setting and P2.

Any comments...dont have the jpg(s) right now
Thanks
Julian

Sounds like a bit too much for the P2 profile - maybe try 350g (I usually use 330-350g on the 1lb profile).

[CafeLotta]

.......ie 400g a bit too light for the 1lb setting and P2.

Hi Julian,

When I roast a weighed 1lb, (454gms), on P2 I normally use 1lb-P2-B which indicates a roast cycle of 20:00 mins on the display before pressing START.

Depending on the bean variety and how dark a roast I'm after, I've hit cool anything from a couple minutes before end of the roast cycle to almost letting the cycle finish. Usually gets to the full power section at the end which moves things along quickly. Will be 10-20 secs either side of 3 mins duration between 1C and 2C as a guide. Never been outside the recommended 15-20% weight loss after roasting- usually 15-18% from memory.
Behmor quote 3:10 min between 1C and 2C for 1lb in their "Rosetta Stone Key tip" so its in the ball park. For 1/2lb they quote 2:10min between 1C and 2C as a guide.

Not all Behmor units will behave exactly the same. Firstly assumes you have set the voltage correctly as per manual before first use? The voltage you are receiving through the power point will vary slighlty from 240V too. Its also important to clean regularly as per the manual instructions, especially in the area inside the roaster where the sensors reside - http://www.behmor.com/docs/Manual_Up...and_DC_Fan.pdf - this can effect how the roaster behaves.

Ambient air temperature, humidity, bean moisture content etc will also play a part in how long the roast takes.
