Application Background
Soybean lecithin is a nutritious natural product, rich in unsaturated fatty acids, phosphatidylcholine, phosphatidylethanolamine and other beneficial ingredients. However, lecithin extracted from soybeans often contains more impurities and needs to be purified through a series of processes. In this series of processes, the tubular centrifuge has become a key equipment in the soybean lecithin purification process with its unique separation effect and high efficiency.
Working principle of tubular centrifuge
The tubular centrifuge uses a motor to drive a tubular drum to rotate at high speed, and uses centrifugal force to separate solid particles from liquid in the county suspension. In the process of purifying soybean lecithin, the county suspension is mainly composed of a mixture of lecithin, oil, water, etc. When these mixtures enter the drum of the tubular centrifuge, under the action of centrifugal force, the denser lecithin particles quickly settle on the inside of the drum to form a solid layer, while the clarified oil and water remain in the central axis of the drum, thereby achieving the separation of lecithin from other components.
Application advantages
1. Efficient separation: The tubular centrifuge has an extremely high separation factor and can separate materials with small particle size and small solid-liquid density difference, such as tiny particles in soybean lecithin.
This ensures the purification effect of lecithin and improves the purity of the product.
2. Large processing capacity: The drum of the tubular centrifuge has a large aspect ratio, and the material stays in the drum for a long time, which greatly increases the processing capacity. This is of great significance for the large-scale production of soybean lecithin.
3. Energy saving and environmental protection: The tubular centrifuge has low energy consumption during operation, and due to the good separation effect, it reduces the burden of subsequent processing, thereby reducing overall energy consumption and production costs.
4. Easy maintenance: The tubular centrifuge has a compact structure and good sealing performance, making the equipment more stable and reliable during operation. At the same time, the maintenance of the equipment is relatively simple and convenient, reducing maintenance costs.
Application Examples
In the process of purifying soybean lecithin, tubular centrifuges are usually used in the following links:
1. Oil foot separation: In the initial extraction process of soybean lecithin, large amounts of oil feet will be produced. By separating the oil feet with a tubular centrifuge, lecithin can be effectively separated from other impurities, laying the foundation for subsequent purification.
2. Decolorization and dehydration: In the process of lecithin purification, decolorization and dehydration are required. The tubular centrifuge can efficiently remove the pigment and moisture in the lecithin and improve the color and transparency of the product.
3. Finished product purification: In the finished product purification stage of lecithin, the tubular centrifuge plays a key role again. Through further separation and purification, a high-purity soybean lecithin product can be obtained.
The tubular centrifuge plays an irreplaceable role in the production process of soybean concentrated lecithin. Its high efficiency, stability and energy-saving characteristics make the purification process of soybean lecithin more efficient, environmentally friendly and economical. With the continuous advancement of technology and the deepening of application, the application prospects of tubular centrifuges in soybean lecithin and other fields will be broader.
