Behmor

[bennett]

1) check to make sure the bean cage isnt hitting the chaff catcher

2) oil up the axle with some cooking oil

try those to see if it helps?

I thought about that too, but it starts and stops at different times of the roasting cycle. Surely if it was catching on something it would happen the whole time?

I will do another roast tomorrow and try and record the whole thing from start to end so you can here when it comes on and off. It is quite strange as Bennett said it does not make a noise from start to end while its turning.
Lemoo number one is definately not the case. I will look into number 2 tomorrow and report back.

Thanks

sooo who's taking up the 500 gram challenge?

I've already done one and it turned out great

Hey, ShapeShifter - can you share your settings, please? I've tried 2 x 500g roasts now and both ran out of time too early just on first crack...

[lemoo]

hmm the other possibility given when it starts and stops is a piece of metal expanding due to heat starting the noise and then contracting back to normal during cooling stopping the noise

just looking at the moving parts in the behmor and you should be able to isolate the sound by trial and error

try running a cycle without beans or the bean cage in for that matter, if the sound doesnt come on then we'll be able to isolate the sound to the addition of a bean cage if you get what i mean

and then work on that?

Hi Di and specialpants

I used 1 P2 C

500 grams of Kenya Kagongo Peaberry, I was thinking a hard bean might be the best way to go for the first go as much as I didn't want to waste it.

I only preheated for a minute, up to 115 degrees. The roast took 19:40 minutes, 1C at 14:15 229 degrees, 2C 19:30 218 degrees.

I think it turned out ok, not completely thrilled with it, I personally think it was too long (my 350 gram roasts only tend to go to 14 minutes on the same setting) and hence it took a lot of the sweetness out of the bean, it's very mellow, still completely drinkable though.

I don't know why I can do this, I might have hit upon a over specked machine, we do have over the normal voltage going through our house though, often we get readings of 249 and that is from the end of the extension lead.

[Coffee2Di4]

Thanks for that - I'll give it another go with a different bean (just got a dozen or so to choose from!)

Well i just did my first Behmor roast and it was very different to my I-Roaster. Did 315gm of Peru on the 1lb p2 b setting which was 20 min. The first crack was loud and distinctive at around 11 mins and rolled for a couple of mins around 14.30 mins second crack started and i pressed the cooling button. The second crack rolled for around 1 min while cooling and it turned out cs-9 to 10 which is what i wanted. So easy to Roast. Very Happy with the results and can't wait to taste it.

I am at that just about to do a second Roast for a friend. lol

Behmoor Roaster

Can someone help with a foolproof profile for roasting PNG Whagi beans. I currently use 1/2 P2 B and don't always get to the second crack, despite ambient temperature differences. Also am I better to roast to a bean temperature and if so how can I do that with my Behmor. Any assistance would be appreciated.
Thanks

[Kevo]

First question from me would be; How many grams are you putting in at the 1/2lb setting?
And, believe me, nothing is "foolproof" when roasting is involved. Too many variables.
227gms is equivalent to 1/2lb, so if you are by chance using 250gms, you will struggle.
Either way, try reducing the bean mass to around 180gms for that setting.
You will no doubt have to hit "cool" early and/or open the door to avoid over roasting (eg: 3rd crack!)
Cheers.

[Coopers]

Thanks Kevo. I roast 225g at a time but looking at ways of roasting larger quantities with ease. Any thoughts on using temperature measurements to roast to?
Here's to great coffee.

Hi N, I tried the Kenya Kagongo as a 1lb roast as a comparison to the sample you gave me.

As you stated, I found yours to be very mellow, more so in milk and as a long black. A short black was a pleasant, smooth taste, without a lot of aftertaste.

I roasted them on the 17th, using 1 P4 D, plus ed out to 24:30min. Let it run the full program, including "cooling". Came out as 411gms, slightly darker than yours and found it very tasty after day 3. Now at day 10 and improving I feel. Still a bit on the mellow side in milk, but importantly, very drinkable.

Of course, the next step now is to get a sample to you for some feedback.

Here's to great coffee.

I suggest using the 1lb setting - my first 2 roasts finished too early with 250g on the 1/2lb setting. I've done over 40 roasts now with 312g beans on 1lb P2 C. Always press cool myself rather than letting the roast finish.

Coopers the thing with the Behmor is that all aren't equal, so what works for one doesn't work for another, I don't know that that is specifically the Behmor itself but the current you have running through your house.

One of my friends can't do 500 grams in his, he would be lucky to even get second crack and that is pressing the + as many times as he can.

I normally roast 350 to 400 grams and for the same quantity he will have to use the whole time whereas on the same setting I'm lucky to get to 16 minutes and that is with a variety of beans. I can't remember what volts are through his house but as I've said I get 249 through the end of an extension cord and his isn't that high plugged into a power point.

Most people I've found with them use 300 - 350 grams on the 1 P2 C setting and then + or - as they see fit at the end.

Kev I'll have to come visit and try some on your machine I think
