Plate Chiller as Step Mash Heater ?

Postby Pjam » Wed Aug 12, 2015 20:25

I've been lusting after a plate chiller for a while. Do you think it might also work the other way around? I'm trying to justify getting one.

To explain:

I return the first runnings to the tun. Via a pump it circulates though the plate chiller and mash tun ...... while the HLT water, also through the chiller, has it's temp raised.

Am I missing anything?

it would have to be finely filtered otherwise any particulates will be getting stuck in there

I think it would be riskiy putting the runnings from the mash through it to many particles.

Not really Mark. It would work briefly and then block. The pump might be able to force stiff through but eventually it will block. . . . Not enough area as a filter.

Do these plate chillers readily block when used for wort? When I first open the boiler tap I sometimes get a little cloud of particles ..... stuff that has settled in the manifold

You need a filter in front of them that stops anything larger than 0.5mm getting thorough . . . and obviously if you are filtering that fine, you need a large surface area. This is why I use a 8" diameter circle of #30 mesh in my copper

Also, surely the HLT water will already be at a higher temperature than the first runnings so you'd just end up cooling the HLT water and heating up the runnings?
