If it were a one-day deal or the like, I'd agree with you, but I'd
choose refrigeration in a heartbeat for any regular use. I'm intimately
aware of the hassles of salt-ice refrigeration, and I'm quite certain
that if I were making ice cream and sorbet as a busness rather than for
myself, it would be an easy decision to spend the money for a
refrigerated mixer - for home use it's a lot of money, so I use salt and
ice.


Another approach would be to use a solid state cooler and a bit of
compressed air.

Peltier Junction Thermo Electric Heat Pump


One could refrigerate a jug of water for a few days
then use it as a heat sink for the copper tube.
That'd be inefficient but it might be cheaper
because it would eliminate the trip to the store
for bags of ice.

Who needs a store? I make my own ice in a little stand-up freezer. In
the summer, when I'm fishing, I make about 10 to 20 pounds of it every
couple of days.

Like this?

Nifty! And probably a *lot* more energy efficient than the Peltier.

So, locate a square 10 gallon bucket, submerge coil, fill with water
and place it in the freezer. Figure out a pump to keep the drip leg
dry and Bob's your Uncle.
