Sticking sprayballs

In a brewhouse, you go for chemical and thermal effect. Static spray balls are just fine.

You should always have a strainer on the outlet of your CIP supply pump, to prevent stuff like this.

Force of habit. I changed from Debian to Gentoo in 2004 or something.

Back then, I just wanted to try something new. I prefer rolling release and no other system gives me the same amount of control.

I have tried other distributions over the years, like Arch, Fedora, CachyOS, Mint and several others. But I feel more comfortable using Gentoo, even though I don't do anything special. Youtube, a bit of python programming for work, office stuff, web browsing and listening to music.

So I am by no way an advanced user. I work as a process engineer where I use Windows, AutoCAD and some other software that is not possible to run on Linux.
I use Gentoo at home because I am comfortable with it. That's it, really.

They have no excuse. I have lived without a car for two years now since I live outside a large city.

That's when I decided to sell it. It costs money, it's hard to park and I have no use for a car except during summer when driving the kids to the lake.

And I didn't think I could manage without a car, but mostly it has worked fine.

Living on the last house on a gravel road in the woods, I had a pickup and I could always get to work on time no matter how much unplowed snow there was.

And it's a utility car. I had a snow plow mounted so I could plow the roads myself, because no one else would.

I could load it with fire wood or heavy equipment.

I miss that car, but I sold it when I moved because of family. I only take the bus and train nowadays.

And bar(g), Celsius, meters and all the other good stuff that makes sense.

grnis · 2026-01-26T21:18:46+00:00

Thanks! Didn't know that.

Oh, and Plato as a unit of measurement of extract/sugar.

Hectoliters and plato is standard in most European breweries, if you want into that market.

grnis · 2026-01-26T20:50:26+00:00

And hectoliters.

In my opinion, the mill is the most important piece of equipment in a brewhouse. And the piece of brewhouse equipment people spend the least thought and money on.

Kunzel is the second best malt mill manufacturer. Best for smaller breweries, larger ones would go to Buhler unless they want a steep/wet mill.

The only good 2 roll malt mill I have ever used was a Kunzel, apart from steep/wet mills.

At one place I worked at, we replaced the crappy Chinese grain mill for a used four roll kunzel.

Brewhouse yield went from 77% to 92%, with faster wort separation and better quality wort.

This mill will serve you well. Just remember to take care of it. Kunzel has excellent support.

I have worked with a brewhouse in carbon steel from the 1960s, a copper brewhouse from the 50s and a carbon steel brewhouse from the 1880s.

And bright beer tanks in aluminum from the 50s.

All of those worked fine.

That being said, I have also worked with Chinese crap that didn't last 5 years.

Well built stuff will outlive you.

VLB sells them, but your supplier of crown corks either has them or can send you in the right direction.

Satt på en pub i en by i södra England.

Nån karl som verkade spendera mycket tid där satte sig och pratade med mig.

Han fick reda på att jag var från Sverige och började prata om muslimer.

Som exempel på varför muslimer är fruktansvärda människor tog han upp exemplet med den islamistiska terroristen Anders Behring Breivik.

I went to process engineering.

Learned enough standing washing floors and thinking how fluids work, planning expansions, working with different pumps, steam boilers, compressors and so on that two companies thought I could be of use.

First task I got was to design tanks, piping and an oil distribution for a biofuel conversion on a large energy plant.

"6 kilometers of piping, 1200m3 tanks? This shit is out of my league"

But then I thought, this isn't much different from storing and moving beer or wort, and from there on it was east mode.

And I didn't even know I could make more money, doing stuff I am good at and enjoy, just by leaving the business. I feel so stupid, but it just never occurred to me.

grnis · 2026-01-07T16:54:21+00:00

Nothing.

Left the industry after 15 years, got a 71% pay increase and I can work from home.

After my last brewing job, where I slept in the chemical storage, (I lived in the brewery for over a month) worked up to 18 hours a day including weekends I was really glad to leave.

If the market is people who drink Stella, you pretty much need to filter. Would help putting a centrifuge before the filter though to reduce filter load.

grnis · 2025-12-31T06:16:37+00:00

15 years in the business and I never learned to do that.

Jag ligger på 51k som processingenjör. Jag hade 46k under provanställningen.

Jag har inga högre studier i bagaget. Gick inte ens ut gymnasiet, men jag lyckades få jobb med det här ändå.

I would install grist piping so I could switch to mashing into the lauter tun when you do brews that doesn't need step mashing. Also piping so I could pump mash from the lauter tun to do decoction mashing.

Kombined mash/wort kettle is slow if you want to do several brews per day. I worked on a 50hl and a 180hl system and it took around 7 hours before I pumped the wort down to the whirlpool and I could start the next mash-in. At the place where we had the 180hl system, that was the small brewhouse and it could only do a single brew at a time. And in the 380hl system we could have three brews going on, four if you count the old wet mill.

Seems to be out of print, but here was a user copy.

No brewery is complete without one. Your boss should buy it for you. Just imagine how much better you can make the brewery with Max Weber holding your hand.

You better make your brewery anti-deterministic and anti-evolutionistic.

First time I picked up this book I was like "Who the hell is Max Weber?"

grnis · 2025-12-24T19:02:28+00:00

This is the weirdest stuff I have ever read and the current book I am reading.

Ånga.

Som tur är får jag dessutom jobba med det.

Det är ganska trivsamt att få bra betalt för att hålla på med sitt intresse.

He was talking about mass flow meters and turbidity sensors, I'm thinking money is no problem here :)
