I wouldn't trust it. Part of it is not knowing how food grade it is.The other has to do with it being a lousy coolant. The dry ice gets a coating of ice in a hurry and then is thermally jacketed.
I use dry ice quite a bit for fog machines and based in what I've seen I'd never assume it's food grade or clean.
I'm about to start my second batch of beer and was wondering if sing dry ice to cool down the wort would work? I know that some home wine-makers use it. Last i took advantage of cold weather. I really don't want to pay for a wort chiller or run all the water required to use one. I appreciate any and all suggestions

I appreciate any and all suggestions How much beer are we talking about cooling? You can place the pot in the sink if small enough and do a water bath. Or a plastic tub or bathtub if larger. Then dump ice in the water when it's cooled down a bit. When I cool a couple gallons I just do it in the sink and swap out ice-packs or frozen soda bottles until it reaches the desired temp.
thanks for all the suggestions. I think i will cool with the sink bath or just go ahead and by a wort chiller
I also just thought of another question. If i sat the wort chiller in a cold water bath and ran the wort through the chiller would that work, vs running cold water through the wort chiller tubing?
I use dry ice quite a bit for fog machines and based in what I've seen I'd never assume it's food grade or clean. Plus, it's expensive. After using dry ice a few times you could have bought a chiller with the money you spent.
