What is a steam kettle and what is it used for? I looked for it on the Internet but all I could find is pictures and prices and no descriptions of what it is.
Steam kettles are used as heat sources in the restaurant, food service, and processing industries to cook foods and to process them in bottles. Think of them as huge pressure cookers or a different type of water bath. Here’s how one operation uses them to cook lobsters: http://www.rimag.com/020/Ops.htm
