Industrial cooking kettles — design types and thermal processing applications

Industrial cooking kettles are jacketed cooking vessels in which food product is heated by steam or hot water circulating through the double-wall jacket surrounding the vessel. This indirect heating method (unlike direct-fire heating) gives uniform, controllable heating without hot spots or direct flame contact with the product. Key design features include: jacket design (single jacket for low-pressure steam; half-pipe jacket for high-pressure steam; dimple-plate jacket — each affects heating performance and CIP cleanability); agitator type (open-vessel paddle or anchor agitator; scraped-surface agitator for viscous products; no agitator for gentle products where stirring would cause damage); vessel orientation (fixed upright; tilting for easy discharge; tilt-and-stir); vessel volume; material (food-grade stainless steel 304 or 316L, with 316L preferred for salty or acidic products); and CIP capability. Cooking kettles are used in thermal processing for sauces, soups, jams, confectionery, dairy, and food ingredient cooking.
