Steam infusion question

[Cookiebaggs]

That's great. I'm glad you worked out the kinks and can use the same manifold for steam injection and wort collection.

Steam makes brewing a lot easier. I really dig my system too.

Nice setup!

Thanks. The final test will be trying that hefeweizen recipe again since it got stuck during sparging last time when the smaller holes were in the manifold.

Did you ever try that hefeweizen recipe again?

 

[dstar26t]

Sure did. Went all out and brewed a 12 gallon batch without any issues. Used 2 lbs of rice hauls in the mash and did rests at 105, 122, 150 and 170. 90% efficiency. Scored a 35 by 2 judges at a competition, they commented that it was on the lighter side for the style but that's the way I like it.
Also brewed 7 other times without any issues, mostly IPA's with one rest and a mash out.

Dear steam-mashers,

Do you find you have to adjust volume calculations to account for the gaseous water you add turing temperature ramping? Or is the amount of water added minimal?

 

[dstar26t]

I've never measured the amount of water added from the steam but would say it's minimal. When setting up my brewery the first few runs, I never seemed to have ENOUGH water at the end of sparging, that is until I fudged the losses from pump tubing and MLT dead space in the spreadsheet.

I haven't seen anyone do this with a false bottom... any issues with that? (Using a separate manifold of course)

 

[dstar26t]

I'm designing a new mash tun made from a half keg. It'll utilize a false bottom with a steam injection ring around the bottom a couple inches off the perforated plate. It'll also have a height adjustable sparge ring that will do double duty as an additional steam ring for big grainbills. It'll also have an electric mash stirrer and an automated pump drained grant for vorlaufing.

Hey everyone, i just purchased an american 21.5 qt pressure cooker and im having problems with finding a threaded "t" to screw in to the lid. I went to home depot and we determined the size i needed was 1/8th in threaded "t" however when we screwed it in, it would only go part way in and stop. the guy at home depot said it was because the treads on the lid are metric, does this make since? how do i solve this problem?

thanks

I made a sort of bulkhead fitting. Nylon washer on the underside seals just fine.

im wanting to put the valve over where the blowoff is located on the right of the cooker.

would you mind getting more detailed on how you configured yours?

thanks.

There is just a hole in the lid on mine. There's a brass nipple in the brass tee. The nipple then goes through the hole in the top of the lid and the adapter threads onto the nipple on the underside with the nylon washer.
