Filtration and Screening Technologies in the Starch Industry

The starch industry refers to the production and processing industry that primarily focuses on starch as its main product. Starch is an important carbohydrate that is widely found in plants, primarily sourced from crops such as corn, potatoes, wheat, and rice. The starch industry involves not only the extraction and refining of starch but also the development of its derivatives, such as sugars, alcohols, starch esters, and starch sugars. With the increasing demand for starch and its derivatives in fields such as food, pharmaceuticals, and chemicals, the starch industry plays an important role in the global economy. The sustainable development of this industry is also receiving increasing attention, with many companies exploring more environmentally friendly production methods and sources of raw materials.

Challenges

Common issues encountered in the production and processing of starch include unstable raw material quality, low starch extraction efficiency, and insufficient product purity. Unstable raw material quality can lead to fluctuations in starch content during the extraction process, thereby affecting production efficiency, while low starch extraction efficiency may increase production costs. In addition, insufficient product purity directly impacts the performance of starch in food, pharmaceutical, and industrial applications, consequently affecting the quality of the final product. At the same time, improper treatment of by-products and wastewater generated during the starch processing can also have negative effects on the environment, increasing the environmental pressure on enterprises.

• Unstable raw material quality
• Starch extraction efficiency
• Inadequate impurity removal
• Equipment wear and maintenance

Application Exploration

• Raw Material Screening. In the initial stage of starch production, screening technology is used to remove impurities and unqualified particles from the raw materials, ensuring the purity of the raw materials for starch extraction and improving the quality of the final product.
• Slurry Filtration. During the starch extraction process, filtration equipment is used to treat the starch slurry, removing undissolved solids and impurities to obtain high-purity starch slurry, providing a good foundation for subsequent processing.
• Washing and Separation. In the washing process of starch, screening and filtration technologies are employed to separate starch particles from the wash water, ensuring the purity and quality of the starch while reducing water resource waste.
• Wastewater treatment. In the starch production process, screening and filtration technologies are used for wastewater treatment to remove suspended solids and harmful substances, reducing environmental impact and promoting the recycling of water resources.
• Particle size control. During the drying and grinding process of starch, screening technology is utilized to control the size and distribution of starch particles, ensuring product consistency and performance stability.
• Finished product inspection. At the end of the production line, screening and filtration technologies are used to conduct quality checks on the final starch products, ensuring that each batch meets industry standards and guarantees consumer safety and satisfaction.
• By-product recovery. During the starch production process, screening and filtration technologies help effectively separate reusable by-products, such as proteins and cellulose, promoting resource recycling and reducing production costs.
