MyHERMS (automated) build
 
Ok, I think it's time to start a thread showing the state of the art of my HERMS build and give updates until this will start to run properly.

For me it's the first AG system, but I've chosen to follow an automated route, with the brewtroller core to manage my system.

Basically it's a single tier, three kettles with two of them gas powered (HLT and BOIL).

Kettles are around 26Gallons each, I wanna go big! :mug:

My water and wort flows have already been discussed here

The system is going to have 10 motorized valves, 7 of them with two ways and 3 of them with three ways.

Two March 809 pumps will power all the different flows.

Gas is managed by the usual Homeywell items, the same you can see here (thanks to sawdustguy!), with two banjo burners, these.

I've insulated the mash tun, I really like the way wood gives to kettles!

This is my false bottom

To cool down the wort I will use this one.

Three sensors for the temperature and three analog thermometers as backup are available.

Volumes will be monitored with the "bubbling system", here explained.

Now some photos of the actual parts, partially assembled.

This is my motorized mill

The three kettles, the stand is not already planned. I will go with a temporary choice.

That's all folks! More updates as soon as I could spend some (nice) time on this!

I love to see DIY builds. Nice mash tun with the wood addition

wubears71 04-06-2012 01:56 AM

Can't wait to see the finished setup and the beer from it.

thelorax121 04-06-2012 05:58 AM

Nice work! How is the wood secured to the mash tun?

goingmad 04-06-2012 05:06 PM

For the mash tun insulation I've used insulation foam, some insulation material, thermoresistent glue and the wood.

Here you see almost all before the work

http://dl.dropbox.com/u/7969190/Phot...%2050%20PM.jpg

It's not difficult to do, if I did it you can do it for sure!

This is the insulated mash tun

http://dl.dropbox.com/u/7969190/Phot...%2045%20PM.jpg

To complete the mash tun I think to add two ss belts in order to compress together the wood and the other insulation materials in case of future leaks.

Some proceedings in my build.

I've found someone very cheap to weld the xlr connectors to the 16 cables I had laying around. Now the cables are ready!

In the meanwhile I decided to brew a 90% pilsner 10% wheat beer in the BIAB style, using just one kettle.

some wort left, whirlfloc did its job!

I'm quite happy with my first AG experience, breewsmith says I've reached 72% and the beer fermenting seems quite good for a rookie.

Coming back to my build, I had to reduce the size of my ss herms coil

from this

http://dl.dropbox.com/u/7969190/Phot...%2031%20PM.jpg

to this

http://dl.dropbox.com/u/7969190/Phot...%2058%20PM.jpg

and here it is inside the HLT kettle

http://dl.dropbox.com/u/7969190/Phot...%2006%20PM.jpg

this is the current mess I'm working on with the brewtroller setup

http://dl.dropbox.com/u/7969190/Phot...%2032%20PM.jpg

today is the right day to weld the 12 switches (10 valves and 2 pumps). Still 2 to do for the burners.

http://dl.dropbox.com/u/7969190/Phot...%2006%20PM.jpg

some silicon then to better insulate and fix the joints among the small wires

http://dl.dropbox.com/u/7969190/Phot...%2012%20PM.jpg

Next in list are the volume sub-system and the digital temp probes to finish. Time is never enough!

What is your source for the automatic valves and how much did those set you back?

Here it is: http://www.tfjt.com/en/index.asp

around 320 $ for 7 two ways ss valves and 4 three ways brass valves, all 12 V and 1/2" size.

Plus shipping from China to your door.

Awesome build! I am also in the middle of a design for total pre-boil automation, with BCS.
The stainless tubes, is that for a bubbler volume sensor? Ever tested this method, how does it work for you, is it reliable and consistent? I'm most likely going with float switches.


Haha! What is wrong with this picture?

Uh, I haven't seen that finger before! :D

As for the volume sensors, yes, the small ss tubes are for the bubbler system. Not built yet, but looking around to what other bt users are doing it seems quite good. I will report my impressions when ready.

Good choice with BCS, let me know how your build is going as well!
