is my current setup. I have temp readings coming out from the tun and also of the mash itself. I've noticed that when I want to do a protein rest or increase the temp of the mash before sparging I don't get good uniform mash temperatures.
A made up example: The exit temp will be 155, the temp re-entering the mash will be 153-154, but the bulk of the mash can be as cold as 135-140. Unless I stir the mash bed I notice I never good even temperature. Do other people who direct fire their mash, use a RIMS, or HERMS system see the same type of issue? Naturally I don't want to stir much/often/ever after getting my bed settled.
I don't have a picture of my return. I usually just have silicone hose which hits a piece of foil and keep the water level a few inches above the bed. As I write this I feel it might be necessary to have a whirlpool by re-directing the inlet to the side of the kettle? If this is the answer, any suggestions on how to best do this with minimum splashing and not disturbing the bed? I recall someone once posting a 1/2" SS flexible hose with a female end. Anyone know where to find such a thing?
Thanks for any suggestions!
