    For situations like this, thought experiments can take you part of the way, but trial and error is the only way to know for sure!

    Would be interested see some photos/results when you do.

    p.s. You don't need a civil engineer, you need a chemical engineer (although a mechanical engineer would probably suffice) Although it sounds like you've got a pretty good grip of the concepts for a musician.

      Thermodynamics and heat transfer is mechanical, isn't it? I always thought it was anyway! I also try to pick her brain about control systems (the PID) and she defers that one too, despite working with control systems almost daily... *shrug*

      I'll do my best to come back to this thread with helpful results. I am on Uni break in 1.5 weeks. Maybe I'll buy some cheap beans from Andy and see what I can achieve.

        Depends somewhat on the application in question, but mostly just on whether you ask a chemical or mechanical engineer...

          Pretty much any engineer should have the basic concepts and math knowledge to 'solve' this as they've taken College Physics 101. They'd just have to do some digging to determine the properties of the materials they're considering.

            Hence why I continue to hassle my wife regardless! However I also did College physics... hmm. Laziness is grand.

              Don't forget -
              All owners of KKTO designs have the ability to stabilise any green bean load, be it single origin or blends by running the beans for approx 10 minutes @ Thaw to 125 C setting

              Then start the roast at Zero time as normal

              This pre roast process not only stabilises the beans and evens out the moisture content, but it also warms the beans to a level where roasting becomes easier because they have gained a head start

                I second this.
                A very simple and effective process, especially with pre-roast blends.
