Ice can be as cold as you (or nature's hand) chills it. But ice, in a cooler, at ambient temps in S. California, is going to reach 32 F after a time. A capsule only 1" thick is not going to last a long time, regardless of starting temperature, which is why I mentioned originally that you'd want to start with a much thicker capsule. If the capsule is frozen in a typical home refrigerator that is working well and properly adjusted, the temperature will be very close to 0 F. As soon as it is removed from the freezer, the surface will warm to 32 F, and stay there until the whole mass is warmed to that temperature. By that time, much of the ice will be melted, and the ice cream will be very soft. I'd say if the original capsule is on the order of a gallon in volume, the interior should stay cold for a day or two, and give the consumer something like sloppy soft-serve ice cream, assuming it started at 0 F. But, I'm speculating, based on experience with using gallon sized blocks of ice (in jugs for dryness sake) for cooling. They last 3-4 days if I use 3 and have precooled food and beverage.
