1. Corn screening: The first step in the process involves carefully selecting and sorting corn to remove any impurities or foreign materials. This ensures that only high-quality grains are used for further processing. 2. Corn cleaning: After screening, the corn is thoroughly cleaned to eliminate dust, dirt, and other contaminants. This step is essential for maintaining product quality and safety. 3. Soaking: The corn is soaked in a sulfite solution with a temperature range of 49-53°C and a concentration of 0.16-0.18%. The soaking time lasts between 42-48 hours, resulting in a moisture content of 40-50% in the corn. 4. Soaking with old acid: Following the initial soaking, the corn is left to soak in old acid for 9-10 hours. This helps in softening the kernels and preparing them for the next stages of processing. 5. Corn husk removal and germ separation: The corn is broken down to separate the husks and germ from the endosperm. These components are then washed to ensure they are clean and ready for further processing. 6. Slurry needle grinding: The processed corn is ground into a fine slurry using a needle grinder. This step is crucial for breaking down the structure of the corn and facilitating the extraction of starch. 7. Fiber separation: The slurry is then treated to separate the fibrous components from the rest of the mixture. This helps in refining the final product and improving its texture. 8. Starch separation and washing: The starch is extracted from the slurry and washed thoroughly to remove any remaining impurities. This results in a purified starch that can be used in various applications. 9. Drying of protein powder: Once the protein has been extracted, it is dried to form a powder. This process ensures the product is stable, easy to store, and suitable for use in animal feed formulations. powder 10. Grinding: Finally, the dried protein powder is ground into a fine consistency to improve its usability and integration into feed products.
