I love it when engineers post their brew designs (I'm an EE student)! Nothing like a little CAD to brighten your day!

I'm a little confused about how you'll use the system for sparging. Will V1, V3, and V4 be open with the rest closed so that P1 moves water from the HLT to the MLT and P2 from the MLT through the CFC to the BK? My personal preference (although I have zero practical experience, only lots of forum lurking) would be to plumb an additional line from P2 to the BK so you can bypass the CFC. Why did you choose this particular design?

I'm on travel for a month so I can't share any pictures on how I sealed me element for the brews a couple weeks ago. I wasn't completely happy with my setup but it work... I used a o-ring on each side of the junction box and then applied a thin layer of 100% silicone sealant around the hex head of the element inside the junction box just to be safe. I also applied a bit of silicone to the threads before I inserted them into the locknut. Going to be looking for some larger rubber/silicone flat washers/gaskets to replace to o-rings.

I'm a EE by education, employed as a systems eng. The plumbing on page 1 was one of my initial designs and was made with the goal of reducing the number of valves I needed as they were one of the more expensive components in my brewery. Since then I have updated my design and I ordered an extra valve to accommodate. Below is a newer drawing of what I plan to implement:



This will leave the plate chiller out of the equation until it comes time to actually chill.

Looks sweet man. I was lucky enough to snag a slc500 from work and start going at it.





Heres just a rough mock up of the HMI

I have by no means abandoned this effort... My time spent on work travel has exceeded the originally expected duration. In the mean time I have been able to slowly develop some of the micro controller and the LabVIEW code. The HMI motherboard, CPU, memory, and accessories have been ordered and should arrive before I return home.

As soon as I return home the stainless table and sink will be ordered. The final touches to my new brewing room should only take a couple weeks to complete, then the real fun begins.

Finally an update.

UPS brought me a bunch of big and shiny things today:

Large stainless sink with drainboard with a lever operated drain and a jointed swivel faucet. Going to be adding a 5-6' hose and nozzle to the top of the faucet.


The two work tables that will serve as my stand and control/power panel mounts.


I hope to finish the plumbing this weekend and get that sink up and running. The drywall and other finishing is nearly ready to go as well.

While waiting for the sink and tables I have been working on parts of the mcu code and HMI. Below is a shot of the PC and touchscreen running.

Where did you get that sink at? Just wondering as I shop for mine. I would love a drain shelf to the left...

Sink is from eBay. There are a number of sellers that carry the same sinks in a ton of different possible combinations. I ordered a sink with the drain shelf on the left but they shipped me the wrong model. It actually works out a little better for me so I am not too angry.

They come in 15x15, 18x18, and 24x24 bowl sizes. Mine is the 18x18, it can fit a whole sanke.

Nice! I'm also an EE by training (tho I've spent my entire career in software), and this is very similar to the setup I wish to build. Tho I hadn't considered LabView - mostly because I don't have access to it!

This is what I am envisioning for a setup in the basement ... how do drain the sink ? Is that a sump pump ?
