Subject: Behmor P2 - Where should I place reduced power?
 

OK, I've got a few OK roasts under my belt, but so far I'm pretty underwhelmed.  I've got the Behmor timed so that the power reduction is happening right at the beginning of 1st crack.  This takes 13 minutes.  I roast 8oz., set the Behmor at 1#, P2 and Program 3 which gives me a total time of 21:30.  First pop occurs right at 8:30, rolling gets into it after power reduction at 8:20.  First crack seems to last between 3 and 3.5 minutes.  I've been hitting the cool button with 4 - 5 minutes left, which gives the roast time between 16 and 17 minutes.  This seems a bit long for me considering the roast is coming out somewhere around city+.

My questions for those Behmor experts:

  1.  Where should I place the power reduction regarding 1st crack?

  2.  Is 13 minutes too long to get to the beginning of 1st crack?

Thanks for any help or suggestions.

Roast times look a little long in the tooth to me. what's your voltage reading? I try to time my power drop so it happens right before 1c starts . Usually just a few pops of 1c with most varitals and then will go silent until 2c aprox 2:45to 3:00 later or right after power ramps. 1C starts 8:30 to 9 min. in to roast depending on varital.  At C+ I go no longer than 12 to 13 min.

The power drop should be between 1C and 2C. So check your voltage as suggested earlier.

If you are stopping the roast with 4 or 5 minutes on the clock, then you are roasting at 100% power for 13 minutes, then roasting at 70% power for 3 to 3.5 minutes before subjecting the beans to slowly declining temperatures after you hit the Cool button.

You may achieve better results by using P1 and opening the door to cool the roaster after 1C and before hitting the Cool button. If you can stand the mess, you can quicken the cooling period by removing the chaff tray and keeping the door open after you hit Cool. Or you can go all out and remove the beans from the drum immediately and cool them outside the roaster using one of the "alternative" cooling techniques discussed on this and other forums.

If you don't have one yet you can pick up a kill-a-watt meter at lowes for $25 or so.

Yes, I thought getting to 1C was taking too long.

Yes, roasting at 100% power for 13 minutes, which happens to coincide with the very beginning of 1C.  I was thinking this was just too long to get to 1C, especially at full power.  I'm thinking I should find how to get to 1C sooner (suspecting a voltage issue at this point) before I experiment with where to place the power reduction.

No slowly declining temperatures.  I should have stated my cooling technique.  I hit cool and wait one minute, sometimes a little less.  I watch for the heaters to look completely dark, then open the door and immediately stick my shop vac nozzle in the opening.  About a minute of this and I stop the Behmor, reach in with leather gloves on a take the drum out, then dump the beans onto a lasagna pan.  The beans at this point are just very warm.  I put the pan on a cool surface and wave the shop vac nozzle over the beans (haven't lost any yet!).  I would say from 3 to 3.5 minutes after hitting the cool button the beans are down to room temperature.  They then go right into a 1 pint mason jar.  I usually wait 3 days before brewing.

I will get one today.

This has been really helpful.  Thanks, everyone!

Your welcome. What I ended up doing was to run a dedicated line for my roasters. They ran fine from any outlet but power fluctuations at different times of the day were subpar went from 119/123v in the mornings and late at night to 117/119v in the afternoon early evening. With the dedicated line my voltage says between 120/123v no matter when I roast.

Well, I got the kill-a-watt meter and the mystery of the baked beans is now solved.  I ran a cleaning burn (the .25 lb. setting) with the meter where I usually roast and at full power the voltage went down to 107v.  No wonder it took 13 minutes to get to 1C.  I'm starting a new thread since my questions now have very little to do with my original post here.

I wish I could run a dedicated line, but we are planning on moving within the year and everything is drywalled, including the basement where the circuit box is.
