Out of Control
Ah, so I've misinterpreted your post. Is this better:My idea wasn't so much as cooling wort per say. Going opposite in that you're recirculating a fixed amount of liquid, let's just call it what I'm suggesting, a glycol chiller. You're turning your flash chiller into a glycol chiller. ...
The chiller doesn't receive the wort at all, instead water in another tank (the "buffer" tank in glycol cooler designs - you've forced me to do a bit of reading) is recirculated through the cooling (product) coils of the chiller ahead of brewing, and through the CFC to cool the wort when the time comes. The "buffer" tank obviously has much more volume than the chiller and smooths the erratic and limited chilling of the cooler (by maintaining the icewall if not actually converting the chiller to glycol).
And as you've said, no need to sanitise the chiller because wort doesn't touch it. If I've got that right I think I'll be looking into that solution too!
