For some non-conformist reason I’m doing my best to get an eMLT to work without a recirculation pump. I’ve been playing with constant slow stirring. Worked pretty well when I was using a heat plate for the heat source. I never got any scorching on the bottom of the pot, but was worried that, even with the stirring, the grain would mostly be at the bottom at a higher temperature than the rest of the mash. My latest “upgrade” has a heating element mounted horizontally in the pot about three inches from the bottom. The trouble is that I get some scorching on the element. There’s a probe mounted about a half inch away from the element to regulate it, but it’s either an on or off control, so the element has the potential to get really hot when the probe calls for heat. Works fine for maintaining temperature, but can scorch when it stays on for prolonged temperature steps.
Somewhere on this board I read about using a router speed control to regulate temperature. The idea sounded good because this way I could adjust the temperature of the element manually to prevent scorching and let the probe control the temperature of the mash. It would slow the time for a step, but prevent excessive temperature at the element.
So, I’m running some tests on it to see how hot the element gets at different settings on the controls dial. The question is how high can that get before there’s scorching? Has anyone tried this idea to prevent excessive temperatures in their RIMS tube? Even with a PID turning your element on and off, when it’s on it can get the wort and enzymes in it to temperatures higher than you’d like.
