Innovative technology leads to efficient separation
In the sugar industry, separation and purification are key links to ensure product quality and efficiency. With the continuous advancement of technology, decanter centrifuge, as an advanced separation equipment, is gradually playing an important role in the sugar production process. This article will explore the use of decanter centrifuges in sugar production, how they work and the significant advantages they bring.
Working Principle of Decanter Centrifuge
Decanter centrifuge is a separation device based on the principle of centrifugal sedimentation. Its core components include drum, screw propeller and differential system. During operation, the material enters the drum through the feed pipe and forms concentric liquid layers under the high-speed rotation of the drum. Due to the centrifugal force, the solid particles in the material will settle on the drum wall to form a solid phase layer. The lighter liquid will form an inner liquid ring and be discharged from one end of the drum. The screw propeller is responsible for pushing the deposited solid phase particles to the conical end of the drum and discharge them through the slag discharge port. This process achieves effective separation of solid and liquid.
Application of decanter centrifuge in sugar production
In the sugar production process, decanter centrifuges are mainly used in key links such as starch sugar solid phase separation and sugar liquid filtration. Compared with traditional plate and frame filters or vacuum drum filters, decanter centrifuges have significant advantages.
1. Efficient separation: The decanter centrifuge can achieve rapid and continuous solid-liquid separation, greatly improving production efficiency. At the same time, its separation effect is also better than traditional equipment, which can ensure the low water content of solids in the sugar solution, thereby increasing the liquid phase yield.
2. No filter aids are required: During the separation process, the decanter centrifuge does not need to add any filter aids, avoiding the contamination of the sugar solution quality by foreign impurities. This helps to improve the purity and taste of the sugar solution.
3. High degree of automation: The decanter centrifuge is equipped with an advanced control system that can achieve intelligent and automated operation. This not only reduces labor intensity, but also improves the stability and reliability of the production process.
4. High value of by-product recovery: Through the separation of the decanter centrifuge, the solid phase components in the sugar solution, such as protein, fat, etc., can be recycled. These by-products have high economic value and help increase corporate benefits.
Actual cases of decanter centrifuge in sugar production
Decanter centrifuges have been successfully applied in the production of citric acid supernatant fermentation and wheat B starch hydrolyzed sugar production. Practice has shown that decanter centrifuges perform well in separating liquefied liquid and saccharified liquid. Especially when processing saccharified liquid, decanter centrifuges can achieve effective solid-liquid separation despite the high water content of the base solid phase and the difficulty of drying. In addition, the separation effect of decanter centrifuge can be further optimized by adjusting parameters such as feed amount and differential speed.
Future Prospects of Decanter Centrifuges in the Sugar Industry
With the continuous development of the sugar industry, the requirements for separation equipment are getting higher and higher. As an efficient and intelligent separation equipment, the decanter centrifuge will play a more important role in the future. On the one hand, with the continuous advancement of technology, the performance of the decanter centrifuge will be further improved to achieve more efficient separation and purification. On the other hand, the decanter centrifuge will be combined with other advanced technologies, such as automated control systems, intelligent sensors, etc., to form a more complete sugar production line. This will help improve production efficiency, reduce energy consumption and costs, and promote the sustainable development of the sugar industry.
