last ag brew had the immersion heater doing its thing in the hlt.steam wafting out the top.had a look at the temp gauge and it was showing only 30 deg.mmmmm
quick stir and up the dial rose to about 65 deg.
stratification me things(hot/cold layers)
so im now thinking of adding some sort of small motor with stirrer attached to motor to reduce this annoyance.dont want to go too far past my strike temp.
has anyone a decent setup/ pics maybe.
im currently looking at various sorts of motors.
was even thinking about one of those tiny d size motors that run off batteries.

cheers

Nice. Hey Big d, I've got a windscreen motor for a HLT stirrer also. They have a nice speed and plenty strong enough. My main issue is getting a power source to drive it. Obviously it's 12V but draws a fair bit of current (aparently?). I've played about hooking it to a motorbike battery but I will look around for another powersource. A designated powersource to buy is a bit dear, one idea that some one mentioned was to buy one of those neon light kits from Dick Smiths/Jaycar etc as they are a 12V system usually and then flog the power supply from that.

Still investigating and trying to do it as cheap as possible.

Cheers big ears.

How much current do wiper motors draw? 1 amp 12V DC "wall wart" transoformers are pretty easy to come across. If you need a bit more, you could grab an old AT computer power supply and use the Yellow wires. 150-200W PSUs. I'd guess they could put about 80-100W of that into the 12V rail.

I have used old computer power supplies for powering many 12V things around the house, they are bloody brilliant. I got some from work but I've also seen some at the rubbish dump and during curb-side street collections, salvos's stores etc. quite cheap 2nd hand if you need to buy one.

Well I made up a stirrer from a windscreen wiper motor

I mounted it so it is easy lifted on and off the keg , for the paddle I used a piece of stainless , around 65mm wide , goes to the bottom of the keg.
This I will need to adjust to clear my element.

Seems to work well , motor has two speeds , avi is on low speed and this really stirs the pot ! , high speed takes off

All up cost me nothing at all , motor from a wreck , and a few bits of scrap

I think this will work well in the boiler during chilling as well , save having to move the chiller about.

I can just lift it out and drop it into the boiler

im with pomo on avoiding hsa
batz my wort usually chills to 30-33 c within 30 minutes and is more than adequate for piching the yeast.no stirring or anything just the ice chiller.
is working very well so far.
my stirrer is only going in the hlt to reduce stratification.

cheers

If you keep the water moving over your chiller by stirring then the cooling rate is "greatly" increased. For me reducing the time it takes to brew is a good bonus (hence my move towards a thermostatically controlled HLT allowing me to heat the water to the exact temp before I even get out of bed). Don't get me wrong, I love to brew but if my brew day takes 5hrs instead of 6hrs then I really don't feel like I missed out on a whole lot my brewing day :) and by that last hour I'm usually ready to finish it up, start to get tired, maybe make mistakes and I am looking for the end. I think it's not a bad idea, I'm thinking I might do something similar, just drop the paddle into the kettle for 10-15mins before the end when the chiller goes in to sterilise then at shut off just hook it up and turn it on.

Cheers and ideas

Justin
