I'm working on developing a transient thermal model of my mash tun/heat input system to help refine my mash temperature control. I have a single heat input (resistive heating element) and a single thermistor in my closed-loop control circuit. There is a definate temperature gradient across the grain bed I am trying to model to help reduce overheating the mash. Does anyone have info or an idea on where to find bulk thermal properties of a mash, or any grain/water mixture? Specifically I'm looking for thermal conductivity and how it relates to grain concentration.
Thanks!
Thanks!
