tarheels; I was planning on one 4" probe in the side of the HLT around the middle of the keggle between the HERMS coils plus using one of the 8" or 9" bronze outboard racing props of 40's/50's era I have a from the family racing, I must add this item to this project. The prop will be connected to a variable speed stir gearmotor. Zero to 82 rpm motor speed controled from a tennis ball machine I salvaged. It has a 90 VDC gearmotor with controller off 120 VAC. On the discharge of the HERMS coil between the HLT and MLT another 4" probe to get the exact temps entering the MLT when the HERMS circulation pump and stir motor are running. The plan I have is to heat the HLT with 11KW, two 5.5KW elements not in direct contact inside the HLT's water. This quick temp rise controlled by the probe on the side of the HLT until close to the set temp. After i've come close to set temp in the HLT then switch to the MLT and repeat the same heating operation. When the HLT and MLT are near the set temps then have one 5.5KW element under each, the MLT and HLT energized to heat until the set temp is reached. The HERMS pump and stir prop will run thru out the mash process. This way my maximum wattage will be 11KW for both elements, stir motor, the BCS-460 unit a few odd LED lights I might add. Like I posted above going to a 6" long probe instead of 4" but placing it somewhere like 6" off the bottom of the MLT, the temp in the MLT should be rather stable thru out the total mash time, well that's the plan.
With 186 sq/in surface area not counting added area from the dished bottom of the keggles call it 190 sq/in surface area plus electrically heated this allows for low even heating temps from the bottom without hot spots or extreme high temp differences on the bottom that a propane or NG burner might add to the mash. This should result in a low stable temp thru out the MLT. Just a probe order change instead of just four 4" probes from Adam I would add two 6" probes to my order. This way i'll have a probe length choice plus a 6" probe in hand for the future conical fermenter. I will add sight tubes to all the keggles on this project.
Shipping for one $16 item later will cost me almost as much as the item itself. Heck order everything at once and be done.
Unless they make me into a voodoo doll this coming monday plus keeping me on heavy meds i'll end up buying a round of drinks while in this mellow mood. You wouldn't believe how long it took to type this this reply seeing double then walking the house many times as I can not sit or stand very long even the way I feel even on meds. No bier now this really sucks while on heavy meds, I can only sample sniff what i'm missing. Done rambling. And they call this it "better living thru drugs", I hate the dang things just give me my suds. Did I answer your questions or confuse you more? Hell i'm confused myself lately. The wife felt sorry for me and came home with some non alcoholic bier while i'm on these heavy meds plus morphine sulfate when needed. Now that's an insult for the taste buds. About as bad as a UV destroyed Corona, yuck is a mild reply.
