Could i use a ss wort chiller as a herms coil. Just an idea i had when looking on beer hawk as there ã35
It is tricky (impossible?) to get reliable temperature changes from directly monitoring the porridge that is a mash. Better to get the temperature of the mash right then continuously recirculate through a HERMS coil in a PID controlled water bath (HLT?).... It has occurred to me that a cooling coil could be used as part of a HERMS setup if the HLT was controlled by a PID monitoring the wort temperature. ...
Hi Bigcol. When I was building the brewery I was convinced the PID temperature probe had to be after the RIMS heater so temperature wouldn't overshoot. Only now do I realise temperature is unlikely to overshoot by much (unless you've got a very powerful RIMS heater; mine's just 2.4kW) and putting the probe on the outlet leads to torturously slow convergence with the selected temperature. So what I do is dial in an overshoot of 1-2C - sort of destroying the argument for putting the probe on the RIMS outlet in the first place.... The temperature sensor is situated just after the ball valve and measures the temperature of the wort as it leaves the ACE. ...
