Re: Dry Ice (dEmO)

Michael wondered about dry ice: "My concern is the CO2 that sublimates as the dry ice evaporates. Is this a real concern?" I've never used dry ice, but my dad tried it once on some race one time (Bermuda?), with the emphasis on "one". It turns out that dry ice can apparently affect fresh foods, and Dad discovered that a carbonated tomato was not a particularly pleasant foodstuff. I expect that if you have well-sealed packets as dEmO described, you won't have any problems, but I'd use dry ice as a bulk refrigerant for sealed items, and not use it as the general coolant for the "regular" supplies.

I used dry ice. Once. It froze the milk, and other things that I wish didn't freeze. A friend on the other boat in the group used dry ice also. His son put his fishing worms in the cooler. The CO2 did a job on them. I don't use dry ice in my cooler any more. Carl Michael wondered about dry ice: > > > > "My concern is the CO2 that sublimates as the dry ice evaporates.

I used to use dry ice on Mexican races in my Yankee 38. It would freeze everything so you had to plan accordingly. Even with refrigeration in the 1981 Transpac, we just froze everything in the ice chest/fridge and then used another ice chest for things that we did not want frozen. In the long races, we would take the evening meal's frozen component out in the morning and put it in the other ice chest with the drinks to cool them. By evening our "ice cube" was thawed and ready to cook and the drinks were kept cool. The dry ice was never a problem. The CO2 probably went out the drain of the ice box.
