I seem to have problems with maintaining an even temperature throughout the mash process. My current system is dump in the grains then stir well to incorporate. Once this is done, I check the temperature and this is where it all gets highly variable. Some readings , normally down the bottom of the mash are quite high 70 ish, whereas readings at the top edge tend to be cooler 65 or sometimes less. So I stir it well with the horrible plastic mash paddle, or my long spoon. One would think this should even out the temperature and yet within a few minutes its all over the place again.
My setup is a 33L boiler (old tea urn) with a removable strainer at the bottom. The drain tap is below the strainer to filter the grains/hops.
It occurred to me that I could use a pump to take the liquid from the tap and pump it with some force to the top and, using a tangential nozzle to stir and rotate the mash. I could also measure the recirculated wort temperature to control a low power heater in the base.
I think it would make a very poor mans version of a grainfather/ brewzilla etc.
Outlay cost is a pump , some pipe and a temp controller ~£25, and affordable.
Any thoughts or advice most welcome.
