I'm going to build a HERMS (or eventually RIMS) heater to have a better temperature control. I'll use it for both, traditional mash and BIAB.
Reading a lot of threads I still have this question not answered.
The temp probe that control the PID where has to be placed?
I found three options:
1. At the exit of the Herms
2. at the inlet of the Herms
3. inside the mash
The option 3 should give the best control, followed by option 2. Both have the problem of not controlling the temperature at the exit of the heater. This could lead to the problem of having the worth temperature higher than 70 so deactivating the enzimes (or is it only my concern and really this don't happen?).
1 controls the max temp of the worth but it's limited to the target temp so the mash will never reach the target temp.
What is the solution that works for you and what problem did you experience as stability, get on target, ...
An additional solution could be put the probe in the mash and additionally contro the max temp inside the Herms, lets say 75. In this way I shoud get both the advantages.
This could work with Herms but not with Rims.
I need your help, my most critical question is if the enzimes are deactivated or modified it the worth is rised around 80 degrees in the path from the Herms and the mash (where it will mix with rest of the mash).
Thanks
