Open Source Brewing Automation

Came across this site:

If your looking for automation, and are looking to be on the experimental side of things, this is a very interesting project.

Yep, I understand everything they are doing, and have used these controllers before.

This takes the place of the current temperature controllers we have been using, you build your own temperature probes (same ones I built and am using with my internet controlled fridges), uses the same gas control valves, or will work with electric heating elements. Is designed to measure vessel volume using pressure sensors.

Basic pieces parts to replace your existing temp controller and temp probes and control your gas valves and pumps will cost about $180 from these people.

Thats roughly double what the current temp controllers cost, but it gives you the ability to control 8 different outputs instead of the 2 that the current controller supports, and it can be used to measure and control liquid levels.

Its actively being developed, and I think its going to really continue to grow. Since its software, it can be upgraded in the future. The most interesting thing, is that its being made specifically for brewing.

Check out the youtube video of the control system and what it can do.

Hmmm. Now you really can start your brew while you're at work and come home just in time to pitch the yeast. Honestly, it won't take much to move to the point where all you need to do is hit start on the internet and have your all brewed automatically. You could even have a recipe menu to choose from, or even hook it up to beersmith. The only times you would actually have to be involved in the process would be to load grain into your hoppers so the proper amounts could automatically be dispensed into your mill and then to drink the beer when it is ready.

Why bother pitching the yeast? Its got enough outputs and programmability that I could make it pitch the yeast as well.

They also make a fermtroller that can be networked with the brewtroller. And they have these in the store....

I can foresee a day when you just fill your hoppers, hit go, and come back in 4 weeks to pour it out of the tap. Technically, its possible right now if you got the cash to purchase all the valves and piping you need. Those motorized valves will work with both liquids and gas, they claim to have a pressure rating of 1MPa which if I am doing it right equates to something like 145 psi. Thats more than enough to handle force carb pressures.

These things are expandable currently to 32 outputs, 8 temperature inputs, and 4 pressure inputs.

Only thing I can't figure out is how to adequately do clean in place automatically. You would still need to show up in person to get the gains out of the tun and clean it.

Just buy a horse and let him clean out the mash tun! :wink:
