Building a Homemade Proofing Box with controlled temperature
« on: November 09, 2013, 06:22:00 PM »
Hi,

First photos of my future proofing box, size 60x40 (in reality he is same a little bigger, I can put oven racks inside).

I wanted a solid thing, it's solid stuff, the polystyrene is great compressed, the finishes are perfect, the lid closes hardly.

Tomorrow I install the system of heating and control of temperature :

- A heating cable of 15w for aquarium reptiles
- A thermostat and the sensor of temperature

My box is going to be in my garage where it makes generally 14/15 , I am thus going to be able to maintain the inside of the box in 18 for the pizza dough. I could also have a higher temperature for other realizations which also ask maturation (breads, baguette or brioches).

See you soon for other photos of the ended box !

Installation of my proofing box, finalization, test this night.

1- Both entrances with the cable warming to the right and the entrance of the lower left probe + the thermostat which is going to regulate T .

2- The probe placed on one of the sides inside.
3- The cable runs(roams) everything around walls halfway up fixed by some adhesive resisting 80
4- Stabilization for 1 hour in 17,8 , it is cool, I am going to go up a little by taking into account the residual heat of the cable, not to exceed 18 /18.5 , in any case it's fine, that warms quite smoothly....

Looks great. Not sure if you want to take the next step in temperature control ( I am a home brewer, so I have a keen interest in this), but....

Think about a PID based controller with a PT100 type probe. It will "learn" the temperature gradients of your heater and enclosure and give you the most accurate control you are likely to get. I appreciate it's a bit of a technical way to do things, but it will essentially eliminate temperature as a variable - and so make any experiments much simpler and more repeatable. If you are into any kind of "modding" then you'll probably also have fun building a super accurate temperature controller anyway!

For brewing, I use PIDs and probes from Auber (www.auberins.com). They have great prices, fast shipping and all their kit works well. Control to 1/10 of a degree C!

One of these might be interesting.. My brother has an old one that has a digital thermostat that goes from warm to very cold.

True...

I used my wine refrigerator (set at 58F) for a small batch of dough a couple weeks ago.  The problem is that we have more wine than space in the 50 bottle fridge.
