Filtering cold break?

[Fil]

Is it possible?

i followed a hunch and built a cfc i could clean the inside of the beer transport tubes with a brush easily..

the initial plan was to use it to recirculate back into the boiler and try to encourage a whirlpool to deposit the cold break centrally before draining clear of as much break material as possible into the FV.

however after initial testing it appears its efficient enough to use in a singe pass thu straight to the FV.
:)
SO if possible i would like to filter out the break material that should be in suspension and not trapped in any nooks in my chiller

I currently fill my fvs post IC chilling thru a nylon sieve to oxygenate but that doesent filter anything so still get inches of cold break trub settling?

Interesting idea. Looks like a convoluted counterflow wort chiller :)

Just curious, why are you worried about cold break in the fermenter ? Normally the hot and cold break will settle out in the fermenter (if you've cooled quickly enough to cause the cold break to coagulate) and you simply rack off above the sludge on the bottom.

Its not worry about the break so much as wondering if filtering it out is feasible, and if so if anyone has been successful in the attempt.

its a pipe chiller, tho i discovered thats what its called after i started the knock up.. and far from an original ideal. but it works very well and there is none of the doubt or paranoia i know i would have if i used a plate chiller, or more traditional cfc..

That chiller looks immense! I was reading on another post about a similar design, have you got two rows of pipes there? Can't quite make it out from the pic. I have a "traditional" style CFC however with the 10mm pipe I can't seem to get a fast flow going through it with the pump. I think its the transfer from 15mm outlet from copper to the CFC which slows the flow too much...is your's using 15mm pipe? What size is the outer cooling side of the chiller?

I was thinking about filtering the cold break aswell the other day, it would make racking an easier job as there should be a lot less trub in FV? I was thinking about just running the wort through a sieve and muslin cloth on the way to FV?

Don't fear the cold break

Seriously don't worry about. . . .commercial breweries chill using Paraflow chillers and the cold break goes straight into the FV . . .to be skimmed of the yeast head early in fermentation. . . .Of course those of us with conical fermentors can chill . . .allow the cold break to settle, then dump it, before pitching the yeast.

Cheers Aleman, fear it i wont

this pic of the test run with 12 tubes will show the construction better..

using a 12v solar pump with an 8v 2a dc psu (me 18v tatto gun vatiable output psu was acting up - tpically its all sorted now) -- gave me an unrestricted flow thru circa 4L per min with a temp drop to 32C. when restricted to 2-3L pm i was getting 25C readings from the output

its 10mm OD SS tube .2-.25mm wall thickness, (thin)
the water jackets are 1" ID pvc hose, and the H's are 22mm copper end feed and tube, 25mm solvent weld waste tube and fittings would be cheaper in hindsight.

I used short lengths of redundant pre hdmi coax wrapped round the beer transport tubes to support the jacket off the inner tube as much as guide a turbulant flow, when first filling its evident it works well both ways

One thing i noticed when cold testing for leaks the 12v pump pushed cold water up and thru no prob, when just off the boil the pump struggled to move it up to the top of the chiller and i had to suck the out tube a bit to encourage the flow to start not ideal, but i ws using only an 8v psu? so hopefully with more Voltage the pump will push a bit better, and on brewday the 'head' needed wont be quite so high.

my own personal baggage is such i dont trust what i cant see and ive stored enough pvc syphon tubes 'dry' post sanitising only to find em a bit mouldy when next use comes , just left nominally damp.. and afaik copper exposed to acid and when left damp can go green, and thats a bit toxic afaik..

+1 for 's advice ...great to see you've used it in anger Fil :party:

Fill, when you've got this sorted any chance of having a go at one of these for us http://en.wikipedia.org/wiki/DeLorean_time_machine obviously with pictures

If not just a hoverboard will suffice :thumb:

Funny u should say that .. its been called my flux capacitor by a couple of people and the name has stuck ...

I am expected to leave nowt but a crater behind when i pop off :)
