Copper Chiller Advice and or Construction

[Ciderhead]

I have 10mm 30M home made chiller ( formed by wrapping around a keg)and although it gets me where I want to be in 15-20mins, I know I am not getting the most from water passing through after 10mins.
I have been reading a lot recently about chilling as rapidly as possible to minimise chill haze, which I have had on and off.
I was thinking of adding a second coil inside the first? anybody got something like this or thoughts?

[Ciderhead]

What's your kettle setup? Are you leaving cold break material behind?

The copper has been repaced with bazooka screen, but cold break falls right out, and especially now that I add in at 10 rather than 15mins my whirlfloc.
I also read somewhere recently about a pinch of irish moss at flameout?

The Lee Vally club have exactly what you're talking about.

2 cold water feeds (via a splitter) into 2 coils, one inside the other. I believe it cut chilling time considerably.

Somewhere down my todo list as well, but that is some list

[Ciderhead]

Would it not make more sense to get a counter flow chiller?

Transfer to your fermenter *and* chill at the same time?

was thinking that but counter flow chillers although effective are a bitch to clean I understand 
Even considered plate chillers, gonna follow Spuds advice as also seen some fancy ones on Jims.
I will post pics before and after.

There's been a lot of debate about counter flow ( either tube in tube or plate chillers ) and an immersion coil.

The coil drops the whole wort down in temperature slowly.

The counter flow drops the temp. of a small amout of wort very quickly but the bulk of the wort stays very hot for a long time.

"You pays ye'r money, ye' buys the cooler of choice and ye' takes ye'r chances"

Their is NO simple answer to this debate short of a MsC/PhD thesis

You could go to the extreme and build a Glycol chiller...

Basic Brewing Radio did a collaborative experiment with some Australians with regards to chilling or not chilling.
3 way : Immersion chiller, Plate chiller and no chiller. The Immersion chiller used less water and gave better hop flavour than the plate or no chill.

Todays project increase the efficiency of my 10mm chiller from this



to this



I wrapped the copper around a Demi-john, I decided that I was going to solder the joints this time and as you can see plenty of flux and lead everywhere!
I will post how efficient it is after I have given it a go.
Hope the friends of the forest don't realise I have that much copper in my shed

That looks like some weapon alright.

Interested to see how it goes for you as I'm thinking along the same lines

[Ciderhead]

I was thinking if it doesn't work I am going to use it as a Hadron Collider

Grab a small pump and recirculate while chilling. That will drop your times

Wow thats some amount of copper.

I left the pump on after running it to sanitise it at the end of the boil one day. I noticed it resulted in cooling much faster.

[Ciderhead]

I think you will see a fairly modest improvement in efficiency.

Bah Humbug the results are in, Tube you can eat my shorts

Ambient Temp 7 Degrees
Water Temp from Well 6.2 degrees
25 Litre Batch
Water flow 9 Litres per minute


Starting at 2 element full rolling boil

5 Mins 37 Degrees
6 Min 30 Degrees
8 Min 23 Degrees
9 Min 21 Degrees        My Ale pitching Temp v's 16/17 Mins  Previously
10 Mins 19 Degrees
11 Mins 18
12 Mins 16
13 Mins 15
14 Mins 14
15 Mins 13                   My Lager/Pils pitching temp 20/22 Minutes Previously

Obviously harder below 20 but well worth the extra effort especially for my Pils/Lagers lighter beers.
Well happy

Very good. Will your beer taste better now?

Absolutely ya cheeky feck and it will clearer than water that flows from a mountain spring, and smoother than a babies arse and .... Jealousy will get you no where [smiley=tongue.gif]

[Spud395]

Impressive stats, will get around to it sometime (sooner now)
