Filter Press Application in High Concentration Sugar Solution

In the sugar refining process, handling the melted sugar solution containing 65% solid dissolved matter is a key and challenging link. This high-concentration sugar solution has the characteristics of high viscosity, poor fluidity, and easy crystallization, which traditional filtration equipment is often unable to cope with. For a sugar solution with a solid content of 65%, the viscosity can decrease by about 40% for every 10°C increase in temperature. This characteristic makes high-temperature filtration a necessary choice. The application of high-temperature chamber filter pressprovides the best solution to solve this process problem.The application of filter press in high-temperature sugar solution filtration is mainly reflected in the sugar production process, and specific applications include sugar solution filtration, activated carbon decolorization filtration, and resin regeneration filtration.

‌Sugar solution filtration‌: Before the sugar solution enters the subsequent processes such as sugar boiling, the sugar solution is filtered by a filter press to remove impurities and suspended particles to ensure the purity of the sugar solution. Pure sugar solution can improve the quality of sugar and make the final product more in line with the taste and needs of consumers.

‌Activated carbon decolorization filtration‌: In the sugar production process, activated carbon may be used for decolorization to remove pigments and impurities in the syrup. At this time, the filter press can be used to separate the activated carbon from the syrup to ensure the purity and color of the syrup. This step is of great significance to improving the appearance quality and market competitiveness of sugar products.  

Resin regeneration filtration‌: In the ion exchange resin process, the resin needs to be regenerated regularly. The filter press can be used to filter the resin regeneration liquid to remove impurities and suspended particles to ensure the regeneration effect of the resin. This helps to extend the service life of the resin and improve the overall efficiency of sugar production.

Actual production data shows that the use of high-temperature chamber filter press can greatly improve the filtration efficiency of sugar solution, greatly reduce the loss of residual sugar, and significantly improve the yield and quality of refined sugar. At the same time, the high-precision filter cloth used in the chamber filter press can effectively intercept colloids, pigments and fine impurities in the sugar solution, while allowing sugar molecules to pass smoothly, achieving efficient solid-liquid separation.

As the sugar industry continues to improve its requirements for product quality, new and upgraded intelligent equipment has begun to integrate temperature and pressure online monitoring systems and automatic cleaning devices, and realize full process automation through PLC control. This technological evolution not only makes the treatment of 65% high-solid content sugar liquid more accurate and efficient, but also lays the foundation for sugar factories to achieve intelligent manufacturing and create greater value for sugar refining processes.
