You can really use nay cooler for dry ice. The trick is being able to buy small amounts of dry ice. Here in Ottawa I can't seem to find any dry ice under 50 pound slabs.
Find a co2 fire extinguisher.. (They don't have pressure gauges) grab a pillow case.. Or clean sock... Cover end of nozzle blast off extinguisher.. Voila.. Dry ice.just make sure it is co2 and not a powder... Co2s are the only ones that have no pressure gauge..Quote:

We use to make a cooler using 2" blue insulation foam, plywood and 2x6 sides. We would go to the local welding supply shop in thunder bay and he would cut the dry ice in 1/2" thick slabs. Wrapped the pcs in newspaper and laid our frozen bear packs from the local butcher out in the homemade box / cooler and then topped it off with another layer of dry ice. Laid blankets over the box and put our gear on top and nerver had a problem driving home. Still had ice when we got home and this was always the first week of June. Oh and the box was for the back of our truck and if I remember it was 4' wide and 6' long and 6" deep
We use an old chest freezer for our moose hunt. Works great but the dry ice freezes everything solid you have to thaw it forever to be able to cook anything.
Dry ice(solid CO2) is -40 or colder.. You don't need much to cool/freeze a large insulated box.
On the SAFETY side remember the box will FILLED with CO2. Don't be breathing it well leaning into the box, because you will not even know when the lights went out. If you are lucky you will fall outside the box, if not and you fall with your head hanging in the box you will NEVER wake up.
And do not build a container that cannot release the pressure created as the CO2 (dry ice)evaporates. As it turns to gas it is just like liquid propane, creating a certain vapour pressure the same as a CO2 cartridge at room temperature.
Good point, a latched lid could be hard for the pressure to lift.Quote:

I've gotten bags of pellets from here http://www.praxair.ca/en on Startop Road.Quote:

This is with slabs approx 6x6x3 inches thick. Dry ice evaporates so anything you can do to slow down air exchange extends the shelf life, it needs to be able to vent the gas it generates but the seal around a normal cooler will allow for that, don't air tight the container, do not buy pellets, have them cut it for you with band saw. I usually lay a thin layer of styrofoam or something similar in the bottom of the cooler before putting in the dry ice, dry ice runs at about -80, if it lays in direct contact with the bottom of your cooler and you bang that cooler hard enough it will shatter. I buy mine from Praxair but would imagine any welding supply center would have this. Make sure cooler is in a well ventilated area, Snowwalker is right about the CO2, you do not want to breath the gas coming off this product. Hope this helps.
And don't transport it within the confines of your vehicle. Not in the passenger cab or even the trunk.
Freeze 5 gallon water jugs solid, in a large insulated space they keep cold for some time.
I use a two liter pop bottle in a collapsible cooler to keep my lunch fresh and safe in my day pack. It keeps for a day or two depending on the weather. Nice thing is that I also have a cool drink of water(SAFE) to refill my water bottle for sipping as I hike/hunt/fish. You can always get cool/cold water to refill water bottles from a creek/river/lake( Filtered of course), but where can you find water to drink on a hill top.Quote:

The dry ice is -112 F. so anything it touches will be frozzen

In the future I will add some dry ice to , hoping will last longer
Get my dry ice at Praxair, they will cut you whatever dimension you want off larger slabs. Since dry ice is so cold (-78C) don't lay it right on the bottom of a cooler or other plastic surface, one bang and it can shatter your cooler. Its not so much heat that makes dry ice decline, its evaporation, more air flow, shorter life. So, as mentioned above, wrap dry ice in newspaper, lay on layer of high density foam in bottom of whatever you decide to use as a cooler, layer of cardboard on top (do not let your meat come in contact with something thats -78C, it will burn it), pack your cooler with whatever you intend to freeze, if possible, another layer of high density foam on top, close and seal cooler. Open as seldom as possible. I've done this going into the bush so we could have steaks etc all week long, have pulled rock hard pork chops out of the cooler on day 6. That was using cheap big blue Walmart cooler with above packing method. Snowwalker is bang on, dry ice is dangerous of you don't respect it, keep it in a well ventilated area, don't put it inside your vehicle etc, as it evaporates it bleeds CO2, this can kill you, do not handle with bare hands. Do throw a chunk in the edge of the lake in about 6 inches of water and wave your lighter over your head, very cool.
