    Behmor Temp Drop

    Every roast I get a nice ramp up, then a rapid temp drop, is this normal? I'm not sure if it's the fans turning on or something, bit it prevents me from being able to have a consistent ramp up?


    Would love some feedback from other Behmor roasters!

    Cheers

    Its likely the after burner kicking in which happens around the 7minute mark from memory for 400g setting roast. As to whether it should drop that much or how to avoid it, that's another question.

    Where are your thermocouples positioned? What profile are you using on the Behmor? If you are using P2, for instance, the power will drop for 100% to about 60%, after 60% of the planned roast time has elapsed.

    G'day Barry, using any profile, this particular one is manual mode p5. Thermocouple top left as per instructions.

    Cheers mate!

    Temp drop is expected when the afterburner kicks in. Try not to fuzz too much about it. Behmor users with bean temp probe have reported that the bean temp drop is negligible at this stage of roasting.

    I had the same thing.
    Adjusted temp probe to inside the drum... it continues to rise really nicely, so don't fear- bean temp increasing nicely the whole time.

    Grab a bead probe and measure bean temp. Pretty easy to do.

    I'm not sure you would get much valuable info measuring air temp?

    Cheers

    Cheers guys, reassuring to know that the bean temp isn't rapidly dropping. Appreciate the feedback!
