Principle:
Steam Jacketed Kettle Uses steam to provide uniform heating to the contents within the kettle, typically for cooking, mixing, or concentrating solutions.
Construction:
Kettle: Typically made of stainless steel, with a hemispherical bottom to ensure even heat distribution.
Jacket: A double-walled structure around the kettle where steam is circulated.
Inlet and Outlet: For steam entry and condensate removal.
Lid: Often included to minimize heat loss and contain vapor.
Mixer (optional): For stirring the contents to ensure uniform heating.
Working:
Steam is introduced into the jacket, heating the inner kettle surface.
The heat is transferred to the contents inside the kettle, causing them to cook, mix, or concentrate.
Condensate is removed through the outlet, ensuring continuous steam supply and consistent heating.
Uses:
Cooking and preparing food products like soups, sauces, and jams.
Concentrating solutions in the food and chemical industries.
Heating and mixing various ingredients in the pharmaceutical industry.
Merits:
Provides uniform and controlled heating.
Versatile, can handle a variety of products.
Easy to operate and clean.
High thermal efficiency due to steam heating.
Demerits:
Limited to batch processes.
High initial cost for equipment.
Requires a continuous supply of steam.
