Yeehah! Did ya see those "heat devils" spinning off the Temple Burn?!
I bought 200 pounds of dry ice Saturday August 23. To my surprise, it turned out to be in bulk -- pellets around half inch in diameter. I was in a hurry, so I didn't ask if it was food grade, but perhaps it was since he normally sells it to wineries. So he just shoveled it into my dead refrigerator's main compartment.
We kept the big door mostly shut, and we put frozen water jugs and food in the former freezer compartment. And ice cream, yes -- some in each compartment. Worked great. But only until around Wednesday, when we had to start putting the food directly in with the DI. And Thursday or Friday we had to start making daily trips to Arctica.
I figure that if I build a plywood and styrofoam box around the fridge, and put a shade awning over it, the 200 pounds might make it all week.
Oh... it cost 88 cents per pound (this price for quantity of 100 to 300 pounds.)
So.... Anybody else have experience with DI pellets?
