Research on the structure of sugar dissolving tank

The sugar industry is actively improving sugar refining tanks and boilers to enhance productivity. Various designs, such as low-pressure head tanks, agitator tanks, and tanks with ring plates or louvered circulation, aim to optimize massecuite circulation and increase tank efficiency. However, even with identical designs, performance can vary due to operational conditions. For instance, a 2°C difference in steam temperature in Hamiltonian tanks can lead to a 16% variation in heat transfer coefficient. Similarly, older drum-type tanks with additional steam coils can outperform newer tanks in evaporation efficiency and heat transfer, despite lower circulation ratios.

Manual operation of sugar retorts often results in inefficiencies. For example, cooking one tank of massecuite in a three-tank mill took 3 hours and 10 minutes manually, compared to 2 hours with automatic control. Automatic systems consistently achieve higher heat transfer coefficients, making them essential for efficient sugar retort operations, especially in tanks with high recycle ratios.
