    Pressurised fermentation/spunding in a Type A keg

    Hi Saxman, hope your aware this a 10 year old post, but as it happens I have one of these WW units, and a very nice bit of kit they are too! You need to back off your PRV to the desired pressure. I found about 15~20psi is about right at approx 20 degrees C for Ale fermenting. Wobbly said 1.5bar...

    Mill Motors

    Well, my little old 2 roller has an 8mm shaft, it was fairly long and had a flat on it for a supplied crank handle, I cut that and shortened it to suit direct coupling to the 90w geared motor with a 10mm shaft, so my set up is 10mm coupled to 8mm. The coupling is a 2 jaw alloy cheapy, but it...

    Ice Bank Chiller - What hose size should I be using

    Right, well there should be a return inlet for the chilled water somewhere, and it depends what the set up is in the font is what you have to work with, probably have to reduce the diameter down, or maybe a bi-pass arrangement that circulates a percentage straight back to the tank. It won't...

    Ice Bank Chiller - What hose size should I be using

    OK, it looks like you have a 4 coil or 4 independent product lines of beer chiller coils there, plus a chilled water pump outlet that can go to the flooded font, and then returns back to the reservoir via (from what I can see) is the larger pipe in the foreground. If you don't use a flooded...

    Fair enough, but are you going to do it.....?

    KegLand Questions and Answers

    What do you think approximate price might be if you offer the dish based Digiboil, and could the 100L version be possible as well? For instance, I use a Rasberry Pi Craft Brewer controller set up, so I actually don't want the controller side of things, maybe leave the pump in place, but a bare...

    GUTEN

    You may be able to stave off a melt down of these cheap ssrs by having a good heat sink with fan. If I had to use one, I would mount a cpu type fan on the side blowing across the 2 vanes of that type of heat sink, or use an old cpu heat sink and fan already mounted, or of course just buy a...

    Motion Dynamics Mill Motor Wiring

    Thats all fair enough, but I think what the calculations also need to take into account is the roller diameter and width. I actually have a 90w motor kk kit driving a standard 2 roller mill with only 1 roller driving and other is passive and it handles the load fine, but I see from the...

    Yes, and what about a 100L centre drain digiboil too!

    Motion Dynamics Mill Motor Wiring

    I can vouch for the KK kit, it does the job just fine, plenty of grunt, only thing I had to do was scratch up the surface of the shafts a bit with a file for the spider coupling clamps to grip better, been powering along for a few years with no problems, good value I reckon!

    Oxebar & PET Sanitation Procedures

    Sounds way to complicated and yes I think your over thinking it! Firstly lets clear up something sanitising and sterilizing are 2 different things. Sterilizing nukes everything, sanitising kills a fair percentage of bugs, generally enough for beer making hardware. Those phosphoric acid based...

    First Brew Fail... I think, help needed!

    Yep, you can control how active the yeast is by good temp control of your fermenter, you don't want a 24hr frenzy and then the party is over, try to aim for about 2~3 days of regular "popping' , then slowing down by the 4th day (for Ale). As it gets slow, raise the temp a few degrees for a few...

    First Brew Fail... I think, help needed!

    You don't want to purge Oxygen before fermenting, only after fermenting! Yeast likes o2 for the first part of its life cycle, and I wouldn't pre pressure the tank, let it build up on its own time. I pressure ferment all the time, or more so do a hybrid, very light pressure (1~3psi) for a day or...
