Whirlpool wort chilling

[mexican]

Hi all,

I've got a query regarding Jamil's whirlpool wort chilling technique.

I'm wondering whether you should be generating a vortex in the kettle while chilling like you can do with a stir plate or are you simply looking at getting the wort moving in the kettle.

Are we after a vortex or simply a slow spinning of the wort ?

Any comments, especially from those who have tried this, would be greatly appreciated.

Also, any idea what march pumps have high enough flow rates to generate a vortex, if a vortex is what we're trying to achieve ?

Thanks,

mexican.

i use my MArch pump and it does a OK job, it does not create a vortex, but the trub does form nicly in the middle

What is happening is the Hot wort is moving around the cold chiller so more wort is in contact with it


In shot it works friggen fanbloody tastic

Thanks OZ.

I've got an aquarium pump that has a slightly higher flow rate that I bought to use to transfer water throughout my system as well as for Jamilz 'friggen fanbloody tastic you beaut chiller'. I just wasn't sure if my pump was pumping enough for the task.

Thanks for the info.

Is that aquarium pump rated to move boiling liquid?

You don't really need a vortex. You don't want to pull air into the wort until it is chilled.

The march pumps will move the wort for 5 and 10 gallon batches with no trouble. I haven't tried it on a batch larger than that, but I would bet that it would work just fine on somewhat larger batches too.

Well, its not really rated for boiling liquids but if you keep the thing immersed in cold water it can do the job. Its the next model up from the one Graham Sanders uses on his system. Its a bit of a bugger to prime properly though.

I've found that it does work but when I did some testing with water and blocked the output completely there was a leak in the body somewhere. This means no fly sparging with the pump. No be deal to me though.

A March pump may be the go, very expensive here in Australia though.

Thanks for the info.

I have used a march pump on Jonny Fitty Gs fitty G system, and it worked ok


However, I realy thing the march pumps could be better, the flow rate is not that great AFAIC

try saying that three times fast.

Based upon the flow rate of a March 809 compared with the aquarium pump I've got there is basically bugger all difference in flow rates. If the head is below 1.5 metres then my aquarium pump overtakes the March. I was a little surprised myself at the flow rate of the March given its cost.

The only other difference is the temperature rating of each. And the price obviously. My aquarium pump cost $52AU. A March pump would be $200+. The prices are going up at the end of this month here in Australia so I want to get in on the cheaper price, only if its really worth it.

At the moment I'm still a little undecided as to whether its worth enduring SWMBO's wraith if I now go and buy a March pump.

Oops, I think the thread is changing topic somewhat.
