Cheap fermenting chamber
« on: May 03, 2009, 02:13:33 PM »
Temperatures here in Orygun are pretty moderate in general, but in the Winter I did have to use a brew belt to warm the wort during fermentation. And with Summer coming I can see the need to cool the wort or provide a cooler space. I envy folks who have a basement. So I'm looking at building a plywood or chip-board box with 2" foam insulation on the inside and be big enough so I could hang a couple of 2 liter bottles of frozen water from the lid (as needed) to cool the interior.

Temperature control in primary fermentation is critical -- so I've invested in Northern Brewers digital temp control system. So coupled with the brew belt to heat and an insulated box with some ice (in the bottles) I should be able to control temps very closely for the 4 - 6 days of primary fermentation. Secondary fermentation I can probably handle by putting the glass carboy in a large plastic tub full of water -- perhaps putting in a frozen 1 liter bottle of water.

I know folks use an old fridge to do this (with a controller) but space is a premium in our garage. And things are tight, with a pay freeze in place (no raise or COLA this year) and a possible job cut.

Feedback is appreciated or any links to systems like this appreciated !!

If you Google the words "son of fermentation chiller" you will find links to a foam box design that works well.  I built two of them and recall they cost about $45 in materials - I got the foam sheet for $10 used.  Even if you do something else, it is a workable design from which you might get ideas.  One key benefit is the light weight.  I just hung mine in the garage to get it out of the way.
