Either one, sodium chloride (common salt), or calcium

 the brine pipes cleaner than does a salt brine. The tables 

 give properties of brine made from these two substances.

The expansion-coils pass through the brine-tank and cool 

 the brine. Special pumps force the cold brine through pipes 

 to the cream vat, cooling coils, ice-cream freezer, etc.
