Using dry ice?

[jltimm]

I'am planning a trip to Canada and was wondering if anyone had some advice for using dry ice to keep some ice for the trip frozen?What is some of ya'alls opinions on using dry ice?

Do not use an air tight sealed container, I repeat no air tight seals! otherwise your gonna have Kaboooooooomm. otherwise you should be fine. also you only need so much. that stuff is cold, negative 71 Celsius (I think) .

Doesn't dry ice melt when it comes into contact with air, hence the fog effect? I thought you wanted to keep it as air tight as possible, I may be wrong though.

You don't want dry ice exposed to air. Buy it from a manufacturer like Jason's dry ice. On our trips we usually buy 110 lbs and keep one block in a 55 lb chunk and then have them saw the other 55 lbs into 4 slabs. Wrap the dry ice in newspaper and handle it with gloves on. We keep it in sealed coolers and have no issues.

Good luck,

Those are some strange numbers W G. 10 lbs?

Dry ice is frozen carbon dioxide. -78.5 C or -109.3 F. It doesn't melt, but sublimates, that is goes directly from solid to gas. That is why you don't want it in a sealed container. wrapping it in newspaper is good. Helps insulate it. Don't touch it with your hands, you will get frostbite.

I believe the fog trick when you put it in some water is caused by the cold carbon dioxide gas cooling the air around it to below the dew point, therefore causing cloud formation.

One other thought. There have been rare cases of asphyxiation from the gas in tightly closed areas, such as cars. So, keep ventilation in mind with dry ice. It really stinks to wake up dead.

Yikes a half ton of dry ice must cost a little bit of coin eh? !!!!

OOps. That was supposed to be 110lbs. The one thing I can say is that dry ice is WAY cheaper if you buy it from the guys who make it.

[jltimm]

Where would you suggest buying it also?

You "want" dry ice air sealed in a cooler or any container. Duct tape your cooler seams etc. You donot want it exposed to air, nor do you want the gas from the "sublimation" process escaping to like inside your car. Always transport it & use it in a "air tight" environment, and use precaution with ventalation measures in cars, tent, small rooms.

A medium size cooler "45 quart" full of frozen product with a 10 lb slab on top of product and sealed air tight will keep that coolers content frozen rock hard for three days. About .045 a pound from a manufactuer in the cities.. Retail you'll get gouged good, and the farther north you really get it.

It does not "explode" unless you are inentionally making "ice bombs" by depositing it into water bottles, pop bottles etc. and putting the cap back on with liquids inside. Its compressed Carbon Dioxide to -109 in to solid form.

The key is, stuff to be frozen on bottom and dry ice on top.

Dixie Carbonic on cty rd 42 in Savage is an outlet to hget dry ice.... ask for Steve!
