Processing technology of corn protein powder
1. Corn screening: The first step in the process involves removing impurities and foreign materials from the corn to ensure quality feed production.
2. Corn cleaning: This stage focuses on further purifying the corn by eliminating any remaining debris, stones, or other contaminants.
3. Soaking: The corn is soaked in a sulfite solution at a temperature of 49-53°C with a concentration of 0.16-0.18% for 42-48 hours. After soaking, the moisture content should be between 40-50%.
4. Soaking with old acid: Following the initial soaking, the corn is left to soak in an acidic solution for 9-10 hours, which helps in softening the kernels and improving processing efficiency.
5. Corn husk breaking and germ separation: The corn is processed to break the husks and separate the germ, which is then washed to remove any residual particles.
6. Slurry needle grinding: The softened corn is ground into a fine slurry using a needle grinder, preparing it for further processing stages.
7. Fiber separation: The fibrous material is separated from the slurry, allowing for the extraction of starch and other components.
8. Starch separation and washing: The starch is extracted from the mixture and thoroughly washed to remove any impurities, ensuring a high-quality final product.
9. Drying of protein powder: After washing, the protein is dried to form a powder, which can be used as a nutritional supplement or feed ingredient.
10. Grinding: The final step involves grinding the dried product into a fine powder, making it suitable for various applications in the feed industry.
This detailed process ensures that the corn is efficiently processed into valuable feed ingredients, supporting the growth and sustainability of the animal husbandry sector. By following these steps, feed producers can maintain high standards of quality and consistency in their products.
