Stainless Steel Spray wort aerators for sale

[Northern Brewer]

Hi Mark
I do like the brass ones but I had a **** week at work and the shiney SS caught me at a weak moment. I may use the brass one as a wort aerator rather than a sparge arm substitute. Still got to make a restricter for the aerator so it sprays properly at 2.5 litres per minute flow rate but I've been building a FV cupboard for my 120L conical and installing new variable PSU for my solar pumps and numerous other tweaks I needed after my first brew.

Cheers
Andy

M you need to start numbering them....mine is the proto type, numero uno...gotta be worth a bit more than copies :whistle: :lol:

:lol: :lol:
Perhaps I should sign each one in case they become valuable when I die :lol:

Hope the ones I've posted recently have all arrived safely - I've had a few confirmations - look forward to seeing some pics of them in action :

I've still got some left if anyone else wants one - see here :thumb:

I was contacted today by Andy from the Isle of Man to ask about postage but unfortunately I have not got his email address. Andy, can you send me a PM - I am not ignoring you, the price is the same because the postage cost is the same :thumb:

I think the surface area of the round plate needs to be alot bigger to cope with the lack of return flow im sure the wort will spread further if the change is made

If the flow rate/pressure isn't large enough the size of the disc won't make a jot of difference. What flow rate are you using :hmm: and what diameter tube? I get a rapid old spread at 2.75ltr/min with 10mm tube. I can't imagine a slower rate will raise the mash temp adequately enough in a reasonable period of time :hmm:

I have the 15mm version and find if I put the pipe right down I get the best spread :

 

[Vossy1]

I would imagine it wouldn't be far off to guess that the speed of the liquid exiting 15mm tube with a 13mm inner bore is nearly half that of it exiting a 10mm tube with 7mm bore (noted wall thickness difference). Hopefully someone will be along to say what the difference may be but I think Cyclops has the best solution as increasing the flow rate by nearly double would be asking for stuck recircs for smaller hb systems.

I have a cunning plan when I get around to it. A piece of 15mm brass rod about 30mm long turned down on the lathe for 15mm along its lenght to make a shoulder that will fit up the pipe. Then drill this out to something like 7mm and fit the spray wort aerator over that. I too get an improvement when moving the pipe exit closer to the cone but still dribbles rather than sprays at under 3 litres a minute. The combination of the two should sort it.

If it doesn't I think I may invent a rotating arm with holes in it, anybody used one before

I don't remember anyone mentioning flow being a problem last time I made some - but then, the 10mm ones were much much more popular - I think I only made a couple of the 15mm ones last time. I use mine for wort aeration attached to the outlet of my counterflow chiller coil - I've not got HERMS (yet ) so have no first hand experience of varying the flow rates.

You can buy brass versions of this currently. I have made a few stainless prototypes which work very well but I've not let them loose on anyone yet

I'll have to take a short vid of what sort of radiating spray to expect, it shouldn't be too powerful as you risk disturbing the grain bed.

What have you been up to in that man lab M :hmm: :lol:

It is only on the HERMS that there is an issue, its not your aerators that are at fault, they are very nice. The brass ones I made (with the help of a mate) do exactly the same. I've only used the 15mm ones so it may be just them. I'm pretty sure its the flow speed hitting the cone not being fast enough so restricting the diameter of the hole may sort it. Will have to find time to experiment :ugeek:

When you make them Andy ill buy the bit off you anything to improve the spread of the wort. It does improve when I move the pipe down to the bottom

I'll knock one up and post it to you Mark if you fancy trying it :hmm:

 

[Mark1964]

Thanks Martin that would be great. I will pm address do you want any thing for it

See PM Mark :thumb:

 

[Northern Brewer]

Let me know how it goes. :thumb: I wonder if the back pressure of the smaller orifice will make the wort leak out of the joint between the pipe and the restrictor? :hmm: Must be a way to seal it, the stainless makes it more difficult otherwise it could be soldered.

 

[Vossy1]

I can't see it being a problem, not that much pressure. I'll have to do that vid of mine, with the aerator out of the wort it is but a dribble but in the wort it nicely fans out....actually....there may already be a pic on the forum.....I'll try and find it :hmm:

 

[EskiBrew]

I'll try and find it :hmm:

This one from the start of this thread??
Not very close up though...

 

[EskiBrew]

Sorry, I didn't realise Mark was using a brass one Northern Brewer had made for him

The trial fitting I have made in SS would most likely not fit because I've made it a tight press fit into one of the SS bodies I've made - I say not fit because the hole is more than 15mm since it's designed to fit over a 15mm pipe.

Anyway, waffling now - I'll have to try it out myself :thumb:

Here's a vid of 2.75ltr/ish/min using 10mm ss tube 1.5mm wall so 7mm ID
I hope you appreciate my gear hasn't been 'wetted' since last March.....no....the grain isn't calling :whistle: :P

EDIT, I think you have to click the link...not posted a vid before :hmm:
