The jacket may have a dimpled or coil configuration to increase the surface area for efficient heat transfer.
To heat the product, a heating medium, such as steam or hot water, is circulated through the jacket. The heat is transferred through the jacket to the product, raising its temperature. The temperature can be controlled through various means, such as adjusting the flow rate and temperature of the heating medium or using a separate heat exchanger to regulate the heat transfer.
Cooling is achieved by circulating a cooling medium, such as chilled water or a refrigerant, through the jacket. The cooling medium absorbs heat from the product, lowering its temperature. Similar to heating, the cooling process can be controlled by adjusting the flow rate and temperature of the cooling medium or using a separate heat exchanger for precise temperature control.
Double jacketed mixing tanks are equipped with mixing mechanisms, such as agitators, impellers, or paddles, to ensure uniform blending and mixing of the product. Double jacketed mixing tanks are designed with safety features to prevent overheating or overcooling of the product.
