Here is a few pictures of the auger http://picasaweb.google.com/kevin.ladue/ScrewConveyor/photo#5188941875307268178

the inner part is 1 1/4" copper with 1/4" od copper tube wound around it and soldered full length, outer is 2" od stainless steel tube. Motor is 1/8 hp tefc with 1" drive and 2 1/4" driven pulleys which delivers malt to mill slightly slower than mill can crush it. What is not shown in pictures is the capacitive sensor at bottom of hopper for the hopper empty signal to the plc hardware. I should have used the opto snap series plc hardware instead of the G1 series and saved a bunch of time writing operating software in C++ as at last test run the code was about 30Mb and the GUI portion is not complete yet. After the brewing system is completed its on to building the carboy cooling and control system that can handle 8 carboys at a a time with individual temperature control and scheduling for ales and lagers. Have enough opto hardware just need a few more solenoid valves and some 12" square copper plates to form to the carboys with 1/4" copper tube for glycol cooling soldered to plates.

Here is the final system configuration pictures showing vent hood and system http://picasaweb.google.com/kevin.ladue/VentHood, still working on software as original application in C++ had issues with GUI widgets written in C#. Resident programmer has re-written entire application in Java and is still working a few last bugs out of the GUI portion, hope to begin final system tuning and automatic operation next weekend. Next step is to finish inside of brew shed and then design and build carboy cooling system with remaining hardware so I can control 8 carboys with individual temperature control schedules.

Too sweet! What a system!

That is too cool kladue
Any chance of seeing a video brew session of it in operation?

Cheers

Wow. I'm speechless.

Can you post a BOM w/ part numbers or part names. I'm particularly interested in what you're using for the flow meter.

wow that's nuts.. I didn't see any water hookups, how are you getting water in and out?

**kladue** · 08-25-2008, 09:45 PM

Water, O2, and propane supply connections are on lower right hand side of panel under mashtun, CFC is glycol cooled and lines have not been run to other side of brewing area where chillers are. Wort exits CFC through O2 injector under mash tun and drops into carboy on floor, gravity flow as no pump was used in that wort flow path.

Seriously....just when I think I am getting the hang of all this crazy jargon....you come out with a thread like this...filled with words I have never even fathomed.....

Back to the damn drawing board....

Oh, and a pretty stellar rig at that!
