Don't quote me this was from memory, but the "excess" or residual heat is used in the process somewhere.asd wrote:orlando wrote:Adnams do but they're no micro.

Does anyone use Steam as their source.
Are you saying they have a heat exchanger configured to the mash tun, so the hot mash, after run off, is used as a heat source? Excellent!

Re: Element sizes for 4bbl brew
The only logical way I can follow this is after they have completed the sparged of the grains they have some sort of heat exchanged connected to the mash tun to extract the heat from the left over mash grains.

Re: Element sizes for 4bbl brew
perhaps the dry the mash and use it for bio fuel or something? (shot in the dark)
Re: Element sizes for 4bbl brew
I would guess he means that the hot water out of the heat exchanger (when chilling after the boil) can fill the HLT for the next brew? About the element sizes, I assumed that the 3kW was to hold at a certain temperature, and the 12kW (and the rest) were to heat up from cold, but was wondering what the 6kW was chosen for? Maybe for a rolling boil? Just a guess though.

Re: Element sizes for 4bbl brew
Well by having 3, 6, 12 kw elements you can have:
3kw
6kw
9kw
12kw
15kw
18kw
21kw
so you have a full range of power at your disposal. Max obviously for heating to the boil and getting it boiling then you can wind back in whatever fashion you like to keep it boiling without causing it to coat the walls.

Sounds good!

Spot on!darkonnis wrote:It takes more energy to heat water than to maintain a boil. So I'd say it's so he can reduce the time required to heat the wort to temperature then, by having 3 6 and 12 he has a good range of power to choose from to maintain the boil.
In the summer, 9kw can hold the boil. In the winter I need to use both the 9 and the 6. This is normally too much and it's a ferocious boil. Having the 3 means I can meet it in the middle.
I'm in the middle of commissioning a new brewery setup so I'll find out exactly how good my thoughts are.

Upgrading eh? Good stuff mate I'm glad it's going well. What you going up to?

Re: Element sizes for 4bbl brew
Where would you buy these hug elements (not to mention the kettles themselves) from?
