Malting Machine Ideas

Postby hjubm2 » Wed Oct 20, 2021 7:42 pm

I think the title says it all, I'm looking for peoples ideas on how to easily malt and kiln grain. I have done it similar to Ruddy's idea in the past but this isn't practical for larger quantities. It's looking like I'll have access to a tonne (or more) of malt grade barley at work so I need to come up with an idea of how to easily malt larger quantities.

I've been looking into all in one machines that can soak, germinate & kiln the grain all in one unit. Currently I'm thinking of a 300 or so litre barrel shaped container with an auger (for lack of a better name) to turn the grain. A mesh bottom to allow water/air to fill (and drain) the machine from the bottom for the soaking and warm air to dry/kiln the grain to different levels (including chocolate/roasted etc).

I'm thinking similar to machines like the Sprowt Labs Acro https://www.sprowtlabs.com/ or the Canadian Malting Barley Technical Centre Malting Plant http://cmbtc.com/facility/malting-technology/.

So what are everyones thoughts? Any info is appreciated/helpful.

That's the way I've done it in the past but not practical for large quantities. Can maybe stretch that out to about 10kg lots but that would mean I'd need to do 100+ batches. Want to be able to do around 100kg at a time, preferably in one unit.

Im all for the DIY approach, but theres a stage where too much is too much and the real thing is easier/better, I think your going to spend a lot of $$ on a machine capable of processing 100+kg of gain once you wet it, how often will it get used?

Theres a few bits of mining equipment that come to mind lols

Neds setup viewtopic.php?f=24&t=12152&p=211217 is about what you want by the sounds, commercial dryers range from 16kg upto 90kg - neds is a 5kg and he rates it upto about 11kg of grain, you may be able to snag a big one cheap if its broken (or just make 10 of them lols),

Event the pros just spread it out and rake it, got a big shed available for a week or two? Maybe an empty swimming pool?

Got storage for that grain while you process it?

A pallet of malt should only be about $2k at trade, jus sayin

44gal drum is capable of 20kg per batch. Steel drums better then plastic. You could do 5 drums at a time?

Maybe you would be better off floor malting 100kg lots.

I agree with RC AL
You really have to weight up the cost and time against buying it in bulk.
I was able to get the malt for zero $
My set up now is similar, but changed the washing machine to a 7kg Beko which I got for nothing also.
I put a variable speed motor on it, but it still works on the same principal as before
I steep 8kg of grain which once germination starts it is equlivant to about 11.5kg of grain, which when dried and kilned comes back to about 8kg
This is a great site of FB if you like FB and it might give hjubm2 the writer some ideas https://www.facebook.com/groups/407322023367882

Thanks for the link ned. Looks like an interesting group. Waiting for my membership to be approved..

I remember watching a video on a whiskey distillery malting room. They had a machine bout size of lawnmover that turned the grain over. Blowed if I can find it again. I wanted to know what the machine was..

Maybe something based on a makita 18v battery...modified cordless wipper snipper perhaps .drum with fins i doubt it would that difficult to make..wonder how much room halt ton barley takes up..

I forsee rodents being an issue..

For a 100kg batch you need a 8x4 area 60mm deep. So not that much room and for that amount you would not need a machine to turn it. Be labourous though turning twice day..

Thanks to everyone for all the input/comments. As mentioned barley malt itself is cheap but if you want anything fancy/different (say a chocolate sorghum malt) it's still expensive.

Unfortunately floor malting isn't an option due to a lack of space & I would prefer an all in one unit that can dry/kiln in the same unit since I'll have to built/purchase a kiln anyway.

Bluc, I have thought of using a steel drum (have access to heaps of food grade ones) to make a vertical malting machine that can be used as a kiln as well. Might have to just do 20kg or so lots for now instead of a couple of large lots. Not overly practical but maybe the best option...

I am toying with idea of table setup. Malt corn is ridiculous $

Gets even worse if your looking for anything but the standard yellow corn... hence why I'm also wanting to malt some of the Hopi Blue corn I'm growing atm... keep us updated if you do follow that line of thinking...
