I might be tempted to go straight to stainless.

The one WA linked to (thanks WA) is galvanised steel.

Guy,

This one,

According to T'internet galvanised is OK at pHs between 5 and 12. Perfect for mash pH.

I'll give it a go to see if the technique works and gives me even temperatures throughout the mash without loads of labour intensive stirring. If it does work I might well go for the 304 stainless one.

I was always taught that galvanised (anything) was a no no for brewing. That said, the contact time is very small.

I wouldn't. But it's each to their own.

Can anyone on here advise, please?

Thanks.

The SS one from Cole Parmer is fairly small diameter and not very aggressive. The paint/plaster one I had before was much more aggressive.

I made one of these years ago, probably before Bac. Much easier, but I have only used it on a

My fabricator has made a few now.

Good for mashing in and whirlpool.

My mixing paddle is manually powered and an earlier version of a Kilner Spatula with a wooden handle. With it I can scrape around the side and false bottom of the mash tun and used edge on will easily cut through dough balls.

I've had difficulty achieving a constant temperature in the mash since fitting 3 thermowells and probes for RIMS project. That has been abandoned since finding that failing, which has been lagely been eliminated in commercial breweries since the creation of the Steel's masher.

My present project has a heater involves a heating element under the false bottom which is powered while the grain is added to the mash liquor. 3 probes measure temperature with a strike temperature of 68C at present, but expect to refine this in time. The results to date have been encouraging, with the temperature gradient gently equalising in about 15 minutes from a combination of gentle stirring and convection.

The element wipes clean as easily as the tun itself with a soft sponge after emptying and a quick hose down.
Without patience, life becomes difficult and the sooner it's finished, the better.

There are always things in brewing which need improving. My current bugbear is the difficulty of getting an even temperature throughout the mash.

After loads of stirring parts may be at 62°C, other parts at 68°C. Which means more stirring until it's right. Very heavy on my wrist and arm, and time consuming.

So I'm now wondering about getting one of these to fit to my drill. Seems like it might do the job.

Is anyone already using one of these, or does anyone have any thoughts?

Thanks.

I am restoring a honey spinner at present. They have a bar across the top with a motor on it. Thought of this thread... Exactly the same tech as a stirrer.

Did you ever build a stirrer?

Hi MB

Yes, I bought the stirrer and it does a wonderful job. Even temperature throughout the mash after a minute or so of slow steady mixing.

My drill is a variable speed one. Wouldn't want to use the mixer on the end of a full speed drill! Plus I have to remember to switch the drill off before lifting the mixer out. Very messy otherwise!
