Personally, I don't think there is enough time for the wort to overheat/underheat while going through the coil, but I have never tested it to know.

Interestingly, I was watching a vid a few months ago where an Ozzy used a windshield wiper motor with a 120v to 12v device to run his.. I wouldn't have thought of that.. Might make a great DIY.
The ice cream motor is way too slow and way too underpowered to crush grain. I'm still racking my brain for something cheap and easy to use for that though.
