I've been an avid homebrewer for over 8 years now and made the jump to all grain last year. I've upgraded most of my equipment and purchased a 40qt rectangular cooler with custom manifold, crankandstein 3E, pH meter, and 2 temperature probes.
I've consistently only received around 58-62% efficiency for any recipe. An example of a recipe is listed below.
5 gallon batch size
Single infusion
14.5 lbs grain bill
18.13 qts of water for mash-in (1.25:1 ratio)
11.8 qts of water for fly sparge
The rectangular manifold was designed with input from the How To Brew book regarding spacing between the sides and number of runs to the drain. It's all copper and connects via silicon hose to the output.
My temperature has always been within 1° to 2° of target and the pH has always been 5.2 or 5.3 without the use of any buffers. I've measured the gap in the grain mill and it is about .045".
Any ideas would be greatly appreciated.
