Fan assisted beer

Does not take long to get down to 85c unless it's a hot day but I am going to use the MashBag fan system from now on

 

[MashBag]

It will be good to see your results. It has properly taken me by surprise.

I did this last weekend, 100°C down to 45°C in a couple of hours for a kettle sour, then after leaving with lacto for a couple of days did a boil in the morning and from 100°C down to 20°C by 4pm for pitching.

 

[MashBag]

Nice one. I am a convert.

I used similar for years, for but it couldn't keep up, when the going got tuff in June, July & August (2022) so I gave in and bought a coil.

Other contraceptives are available!!

Hmmm. That is interesting. I couldn't be bothered with taking the jacket off the BZ every time though, maybe it wouldn't make any difference though (as in it would still work). I could try it by boiling some water and cooling it with a fan.

I rigged up a wood fired HLT at the weekend

well, not really it was a hot tub heater, definitely not an old washing machine drum, copper coil and back boiler water pump. But it got me wondering it could certainly heat a HLT too

 

[MashBag]

It certainly would

Heat stones in the fire, drop carefully into mash, that’s how it used to be done.

I do like fan assisted cooling. I put the beer in the fermenter last night and was too lazy to think about the temperature.

Metabolic heat was pushing it too warm this morning so a t-shirt over the top clipped in place to keep it taut, sprayed with water 3 times a day and a small fan pointing at it has done wonders.

I only need to do this for 2 days before the activity drops and it calms down of its own accord.

You can see the spots where the t-shirt dried out

That's a swamp cooler, works well doesn't it,.

I have an idea to try this with microfibre clothes, dippef in a reservoir and an inkbird controller

Yeah. My t-shirt method takes a few minutes to set up and is a bit of a faff. I'm considering making a "blanket" (nice idea with microfiber - lots of surface area to evaporate) with velcro that can easily be attached. With a little tail dangling down to dip into a water reservoir

I already use the temperature sensor in the ispindel reporting to a homeassistant server to control a heat belt in winter. I can just reuse that with the fan control too cool it.

 

[MashBag]

The microfibre clothes are cheap enough now, and come in very handy squares. It would be easy enough to sew a few together with some velcro on the ends. Shallow 15l trug* underneath. Bingo.

Quick note.

A have a pc box fan, today plugged into the inkbird, which appears to be thwarting a run away day 2 fermentation.

Just a "let's try this" and it only bleddy worked. Happy days.

Fridge pump chiller will be required fitted the next brew.

 

[MashBag]

Report back as I have always just done it the standard way of leaving it in the garage overnight.
It should work just how much time it saves is the question

Quick update.

Cool air fan assisted in fantastic.

I use a 4" extractor fan on a wooden base and some silver hose just to move the stream out off the brew shed.

I have been using the fan without the hose to reduce the kettle temp after boil, works well. But heated the shed up (obvs)

Today the outside air temp was quite cool. So reversed the extraction setup and left the hose on & blew cool air. Temp really dropped off. Will be doing that again.
