  • Behmor Bean Probe

    So I cut up my Behmor 1600 Plus drum the other day.

    I'm about 20 roasts into the journey and really needed to know what temp the beans were at during the roast so I can understand what's going on better.

    Inspired by artman's "wiper" BT probe, I tinkered with some old stainless fittings I had from back in home brew (beer) days to replace the shaft on the Behmor drum door, and bent up some stainless tube to position a 25mm probe for a HeatSnob down into the bean mass.

    As always, this all took some tinkering, but I just completed my first roast with BT and no dramas. Yahoo!

    If anything, the probe is almost too close to the edge of the drum and occasionally bumps one of the horizontal ridges as the drum rotates, but I'll see how I go over a few roasts and can always modify this a bit further to sit up higher in the bean mass. I think that as long I have it in a consistent position for all of my roasts, and learn what the temps that I'm getting mean (and how to manipulate the roast from there), that's the important thing.

    I took some videos of it in action and might throw something on YouTube if i get around to it. The probe is attached to the stainless tube with RTV silicon (technically rated at 260C on the box, so it's a little hotter than that for this application...) and the beans bump against the probe all roast so we'll see how that holds up as well. Overall though, pretty happy with the result!

      Good work, looks shmick!

      I finally replaced my bead probe the other day, did over a hundred roasts with it, including some super hot events that melted the red sleeve a bit into the stainless support!

      Cheers

        Thanks mate. Yeah the BT is great - can't wait to get a few more roasts down to keep the learning curve steep!

          Oh wow! Good effort Yeah hopefully mine is a little more insulated... I'll let you know how it's looking in a hundred roasts' time!

            yours is the "proper" probe inside the stainless tube with braided sheath, should outlast several roasters!!

            I was referring to the "naked" bead temp probe that essentially has no protection at all. Its not meant to do what I am using it for but works quite well regardless.

            Cheers
