Home of the BrewNosers

I'm in the process of building a dead-simple, portable electric brewery. The main requirements are cheap, transportable, and safe. here's a sketch of what i'm planning:
The first part will have two cords, so it can connect to either oven or dryer outlets - so that i can use it anywhere. 30A gfci (spa panel or in-line) so i can use ten gauge after that. then my stilldragon controller. then heat-resistant wire to connect the element via a hot rod heat stick.

Parts I have yet to get:
1. outlets/wire/high temp wire
3. gfci or spa panel

Only one question so far:
1. is there any issue having ~30 feet of wire from outlet to element? I want to keep this setup as flexible as I can, but need to use 10 gauge at the end because of the limitations of the hot rod. Quick googling for a chart shows 30' at 24A (5500W@240V) should use 6 gauge. could i get away with 6 gauge up til the last 6 feet?

If anyone else notices anything or has questions, please post up! or send an email or pm if you prefer to keep your expertise quiet.

I'll keep this post up to date with links to future posts as I go through my build.

This looks super wicked awesome. I will follow this with great interest. Is that a mashtun/kettle/fermenter?

15gal pot from Dave at everwood. The 5500W ULWD element will be a tight fit - has about 1cm to spare from the edge of the element to the side of the pot. If it moves around much once it's assembled, I will have to upgrade to 19gallon. The advantage of this setup is that it would work for any system - can just move the element to the vessel as needed.

I intend to use it as a BIAB system, but I ferment in carboys. Fermenting in the kettle wouldn't work so well for me (would have to change my brewing style - normally I brew a bunch of batches at once, then let them hang in their carboys for a month or three).

How large a batch would this do Liam?

Depending on the size of pot, as large of a batch as 5500w will boil

I boil 52l down to 40l with a 5500 in a 15 gal. You will be limited by your mash size only with that pot and element

This is similar to the build I'm doing but I went with the 19 gallon kettle and don't plan on making it portable so much as reducing my footprint

Think that setup would do a 30 gal batches.

If you could get a jacketed pot that would be nice. Would also allow you to ferment in there, if there was ever an occasion that would work for you.

yeah, if you have a big enough pot. i dont know if BIAB would work for 30 gallons. the big limitation is going to be the amount of time it takes to heat - it could be worthwhile to add a second heat source once you get to a certain point (even just an additional 1500W heat stick). this calculator is useful to calculate boil time:

remember that the element wattage is rated at a certain voltage. so a 5500W element at 240V is only 4100W at 208V. this calculator can help with that (or the equations are pretty simple):

i intend to insulate my pot, reflectix for now (won't melt without a burner below it, hopefully.

Your last 6' using #10AWG will be fine. The voltage drop for those last 6' would be negligible.

This looks really interesting. Have you thought about how you're going to ventilate if it's mobile?

I've been tinkering with a couple ideas of a mobile vent hood that could hook up into a window.

Part if the reason for the 30' of length is to let me get it outside, or at least next to a window. If I set up somewhere more permanently I'll rig up something for the moisture exhaust

Thanks for the vote of confidence Derek

Anyone have suggestions on where to find an L6-30 plug and receptacle? want to use them to connect the high temp wire from the heat stick to the regular wire from the controller.

this sort of thing but without the $15 shipping:

home depot has them, but they're $30 each... would prefer to find somewhere a bit cheaper if possible. anyone have any info on other places to try?

Nedco maybe?

I can't remember if they'll sell to the general public, but I would expect Harris & Roome would have it.

I wasn't happy with the local prices so I ended up getting my plugs from ebay via the US.

Nedco sells to the public, I've bought there before.

Thanks for the info. Nedco looks to have all the parts i intend to get. I'll have to draw up a list and see what kind of price i'd be looking at from them, then decide.

That's where I picked up my GFCI breaker.

The only thing to watch out for in Ebay is counterfeit safety approvals... If you're buying out of china in particular. I've been burnt a few times on small shit where the risk was minimal (just small electronic circuits). A fake 30A plug could be a bigger issue.

Anyway - not to say DON'T use Ebay, just be cautious. If it sounds too good a price to be true, it probably is.

indeed. i could get one shipped straight from hong kong for like $5, but it isn't work the risk.

the only part i am going to be using that came from china is a ammeter/volt meter thing. if it breaks its no big deal. some folks on some still website got one and tested it and it worked well so i figure it was worth the risk

How's your build going? I ordered my high temp wire from ebay a few weeks ago...looking at the tracking...it should be here next week.

waiting on the high temp wire, and a voltmeter/ammeter, plus gotta get a few connectors and some bulk wire for either end. I am not assembling until i have all the parts. Once I start assembling I'll take a bunch of pictures and note what all the costs were for posterity. may not be until july though, june is looking pretty busy as i'm away for a few weeks

Cool! Look forward to seeing pics. I'm in the same boat...waiting on a few items. Just bought a new mountain bike, so the remaining items are on the back burner for now. Will be up and running by September though hopefully.
