Mash Tun on the way

 Finally got notification from SSBrewtech that my Mashtun is back in stock.  Quickly ordered and it should be on its way here soon to complete the system

Design change

So the inability to whirlpool through my chiller has been bugging me for a couple reasons.

• I won't be able to drop temp quickly to get to whirlpool temp (170 degrees or so) 
• I won't be able to chill back into my boil kettle to drop cold break in my kettle 
• I wont be able to sanitize my chiller by circulating boiling wort through the chiller

The last one was probably my larger concern.  Having come this far in this build I decided I didn't want to make these compromises.  I have made some changes to be able to solve these problems.  Essentially this involves a few more three way valves 

Now I can run 

• From the boil kettle through the chiller back to the boil.
• From the boil kettle bypass the chiller back to the boil.
• From the boil kettle through the chiller to the fermenter

Here are the new drawings as well as a picture of the new valves in place.

 An update on my build.

Parts have started to arrive and I have been busy assembling.  The one big piece I'm missing (because it is out of stock) is my mash tun from SSBrewTech.  Im hoping it comes in this week.  I was able to put most of the rest of this together.

I was able to run some leak tests which showed a few things that needed correcting.  I also ran a few tests on the boil kettle.  Looks like I should be able to expect a 3 degree rise per minute on a 12 gallon boil which seems pretty good.  I did have to change the design a bit as I found out that my chiller restricts the flow too much to get an effective whirlpool.  So I modified the design to have the whirlpool branch off before the chiller (instead of after).  Im a little worried that that will mean any cold break material will end up in the fermenter but I think that will be a try it out and see if that is a problem I need to fix down the road

New System (Theory)

 Getting back into brewing the main thing I wanted to do is make good quality and more importantly repeatable beer.  My process before was ok and I made good beer (even won a few metals) but it was never repeatable.  I could brew the same recipe multiple times and it was never exactly the same and sometimes wildly different.  

My issue with my old process was control.  I was able to control some things and not others just too many variables on brew day to reliably make the same beer twice.  So having a bit of extra cash laying around I wanted to solve that problem this time around.  I decided on an all electric system based around SS BrewTech equipment.   I went back and forth on numerous systems and manufactures but eventually settled on SS BrewTech mainly because I really liked their mash tun (insulated with a bottom drain).

So once I settled on the what manufacture I was going to get the system from I started on the design.  Here I made a slight departure from the traditional three vessel approach.  I decide on a two vessel no sparge design for a couple reasons mainly space and simplicity.  I fully realize I will take a hit on my efficiency but efficiency is not my real goal here.  As long as I get reasonable efficiency (around 70%) and more importantly it is repeatable I'm happy

So here is the general flow of the design

    1. Cold water into the boil kettle, heat to strike temp

    2. Transfer to mash tun and dough in

    3. Recirculate during mash through RIMS to maintain and control temp

    4. Transfer (full volume mash) back to boil kettle 

    5. After boil Whirlpool through chiller

    6 Transfer chilled wort to fermenter

here are the illustrations of the steps

  

Long Time

It has been quite a long time and honestly I was a little surprised this was still up.  I took a break from brewing for a couple years but since I'm mainly stuck in my house these days decided to pick it back up.  Im building a completely new electric system which I will detail here soon.  I may have gotten a bit overexcited about this new build and got slightly overboard but I will try and get some pictures up here soon.... stay tuned
