Brewtroller Build Part Four - Volume Sensing

Posted on December 7, 2011 at 4:00pm 1 Comment

I've been so busy with work/study lately I haven't had a chance to finish off my blog series, so thought I better get back into it.

The goal here is to allow the Brewtroller to calculate how much water is needed to brew a particular batch, then fill the HLT with the correct amount, transfer the mash water to the mash tun, and finally sparge until I have the desired amount of water in the kettle. There is actually a particularly useful feature where by you can set the flow into your BK…


Brewtroller Build Part Three - Electric Heating Elements

Posted on April 14, 2011 at 8:30am 7 Comments

I decided to go for 3kW elements, it seems that would be about the biggest I could go for without requiring new switches and fuses in my house. My circuit breaker is rated to 20A, and as a good rule of thumb I'm going to try and keep this below 15A. Basically, the bigger the element, the quicker I can heat the water to start the mash and get the boil rolling.


The Maths:

20A x 230V = 4600W (max)

15A x 230V = 3450W (my target)


Therefore: 3000W/230V…


Brewtroller Build Part Two - Plumbing Fittings

Brewtroller Build:- Plumbing Connections



First off I must say I'm surprised by the total cost of plumbing this system, it's much more than I would have guessed - but it has to be done.

Side note: I work as a sound engineer now, but actually I did my trade as a plumber so the plumbing side of things is going to be a piece of cake for me - the electronics side is going to be a little more difficult - but…


Brewtroller Build: - Mash Tun False Bottom

Posted on March 22, 2011 at 4:00pm 3 Comments

I just got my false bottom back from the sheetmetal workshop so I thought I'd post a few pictures. I bought a sheet of perforated stainless steel sheet from: LockerNZ - http://www.lockernz.co.nz/pdf/catalogues/Perfmetals.pdf

I opted for the P106 which is 2.4mm holes at 3.6mm centres. It comes on a roll which I think was about a metre wide but they sold me just a half metre of that (for about $90), so…


Brewtroller System Build

Well I'm well into my Brewtroller Build so I'd thought I'd document the whole process.


Building an Automated Brewing System



I have been brewing all grain in 20L batches for a couple of years now. I have been using a 32L pot which doubles as a HLT and a Boiling Kettle, recently I started using the Brew in a Bag (BIAB) method which has proven to…

Hi Reuben,

I had mine made at Mahurangi Sheet Metals Warkworth. They were expensive as I had high pressure lids fitted for fermenting under pressere.

Mine hold 75L easy, they work very well and are very easy to clean. I have a number of SS lids (500 diameter) with seals and hinge /lock down fittings if you want one or more they're yours.

I had them fitted on mine at first but could only reach 8 PSI


Cheers Barry

Hi Reuben, hope you brewing has been going well.  I recall you purchased a Bilchmann conical fermenter.  Are you happy with it? And do you mind telling me where and how much you payed for it?  I was looking at getting the 14.5Gal one through i-n-i brewing for $1100.
