    Behmor 1600 Plus Temperature Profiles

    When I got my Behmor, I couldn't find anywhere which showed what the machine was doing with each of the Profile settings. I thought I would upload the results of my measurements in case anyone else is wondering. These were made using a HeatSnob with the probe in the recommended position. Drum and chaff collector were in situ, but I didn't have any beans in the roaster.

    I have only done it for the A settings for 100g. From what I can see there seems to be very little difference between P3A and P4A

    Here are the graphs for the P3 profile on settings A - D.
    The difference between the settings isn't just time, but also maximum temperature. OK, that might have been obvious to everyone else, but I wasn't sure if it left the element on, or held the temperature constant for a longer period.

    The manual shows the profile for each of the five preset programs.

    Thanks. I couldn't find them for looking...

    It seems strange that the temperature in the P1 Profile has a knee and then slows, if the power is full on after 20% of the cycle.
    I have noticed that it makes a click and seems to turn the heat down at about 40%, and then seems to turn it back up again.

    Effect of Preheating

    Another issue I was wondering about when I started was pre-heating. Opinions seemed to be divided as to whether or not it worked.

    Here are the measured chamber temperatures during P3A with and without preheating for 90 seconds on P1A.

    Things might be different if I had beans in the drum.

    What is your concern? Are you having problems roasting beans? And yeh, things will be different if you have beans in the drum. Pre-heating is generally not necessary, though I can't see why it would hurt.

    No problems with the roaster. The only concern is that I can't drink enough coffee to roast more often

    I would have found it easier to get started, if I knew what the machine was doing. I thought I would put the graphs up for others who might be in the same boat.

    In my opinion, pre-heating was suggested when you couldn't successfully complete a near 1lb (454gm) roast with the provided profiles. My Behmor is around 4-5 years old and initially had no issues but slowly seemed to lose the ability to complete larger roasts and then smaller roasts until at around 60 roasts it would only bake and not roast. Eventually, after first changing other parts out, installing the upgraded front panel has it to a point where some time needs to be subtracted at the end of the programmed roasts to avoid over roasting. Most roasts I do now are around 430gms.

    The point I'm making is that there appeared to be issues in the earlier front panels which are now corrected in the "plus" versions and that pre-heating shouldn't be required. I'd imagine this also applies to the later Behmor Plus versions which were supplied with the upgraded front panels from new.

    Regular maintenance in the form of Behmor's cleaning regime and cooling between roasts should help prolong the performance life of these roasters.

    Behmor Coffee Roaster
    With all the great features of the Behmor Plus front panel, one that I keep wishing was there is the ability to display the current element power. This would greatly compliment the feature giving manual control of element power (100%, 75%, 50%, etc). This is especially so after first crack on soft beans to help fine tune the roast depth and avoid scorching.

    http://www.behmor.com/docs/New-Progr...-Plus-V4.2.pdf

    Maybe even a graph showing element power v time throughout each of the programmed roast profiles?
