Cooking potatoes to make potato salad requires a lot of heat, followed by quick cooling before the oil, mayo and seasonings are added. Among the more sophisticated cooking systems that are perfect for potato salad is the vacuum-sealed retort, a vessel used to cook diced potatoes within half an hour, and then chill the product to 35°F within just 17 minutes, through an evaporative cooling system that uses no conventional refrigeration. While a retort works well in this application, it does have to be teamed up with a cooling tower to dissipate some of the heat. This places special demands on the cooling tower.
