Stirring pot

[wallyc14]

This is for those who use a presto pot and a stirring machine. 
1 : do y’all use a insulation blanket around the pot? What’s the real world benefit?

2: How long does it take to bring the plastic up to temp? I’ve done some some research and found the barstools way to heat is a microwave then dump in the pot, however my mics take for ever to heat 4 cups let alone 3/4 of a gallon. 
Thanks for the help folks :-)

I use a blanket on mine.  I also made a lid for the pot that fits around the stirrer.  I wired mine up with a PID for temp control and have noticed the plastic temp (within 2 degrees + or -) is much more stable with the blanket and lid.  Can't really say how long it takes to heat 4 cups I've never paid that much attention to it.  I put the plastic in and set it for 350, putter around and when I see it in the 340 area I watch it until it hits 350, then dial it down to 310 or so.
