Alright I just finished my wofati inspired pig shelter. It was -20C here this am and above zero and toasty in the pig shelter!!!
So speaking of -20. This coming summer I would like to attack a wofati inspired freezer, cooler and possibly a butcher room on the end.
Here’s my thoughts
Build on grade because my farm is totally flat. If I had a hill I would do it differently but stay with me here....
On grade I’m thinking of building a pole barn out of 8x8. Be 8 feet wide, 24 feet long, and 8 feet tall.
This would be shored with full demensional 2x6 walls and ceiling on the outside.
Earth would be Bermed up all the way around except one entrance. The earth will have earth tubs in it to freeze the surrounding earth around the structure hopefully creating a perma frost.
The structure will have three 8x8 rooms inside. The deepest hopefully will remain frozen year round. The middle room acts like a cooler/buffer and the outer room be a 8x8 room for processing. Meat saw, grinder and work table. The unit will have hanging beams and tracks installed to move the animals through.
If I can get the deepest room to remain frozen year round I could use it as a freezer the middle room will be a fridge/“ freezer in the spring” And outer room work area and buffering.
I’ll run the in ground runs tubes in the back. The earth berm will extend out to 20 ft alll the way around and insulated from the heat of the summer. In winter the tubes will be opened allowing the 8 months of cold that we get to cool and freeze the mass. Hopefully I can mimic perma frost here.
Should I use foam insulation for the mass?
Or so thing different and ideas?
I have a sawmill so my logs go a lot farther and building is easier then using rounds. That’s why I like beams and 2x6.
Our winters or quite cold. Last here had a good week around -50C. We often hit -30-40C. When it does get warm it’s -20-15C
Our summers can be warm 21-35C day time temps But cool nights. May June July aug or the warm months
Sept Oc starts freezing at night
Nov Dec Jan Feb Mar Definitely winter!
April freezing at nights. Warmer to cool days
Basically I got 5 months below freezing guaranteed. 2-3 months of buffering temps. Hi
I feel we cold store enough cold in the earth to pull this off if it’s properly designed.
Planning stage at the moment please give me your 2 cents!
I will draw up a sketch when I get a chance
