| 中文摘要: |
| 旨在提升脱酚棉籽蛋白的质量，对现有脱酚棉籽蛋白生产工艺中存在的问题进行了分析，并提出了改进方案。现有的脱酚棉籽蛋白生产工艺存在棉坯粉末度高、棉坯水分含量高以及脱酚棉籽蛋白KOH蛋白质溶解度低的问题。通过将棉仁与棉仁粉末分开处理，并增添造粒机将棉仁粉末造粒，以及将烘干机的出料刮板改成提升机来降低粉末度；采用引风与蒸汽同时烘干的方法来降低棉坯水分含量；采用离心分离技术及时分离物料中的脱酚液，减少脱酚液中的水分含量，进而提升脱酚棉籽蛋白KOH蛋白质溶解度。改进工艺生产的脱酚棉籽蛋白的品质得到了提升，产品质量稳定，而且改进后的工艺能耗降低，节约了成本。 |
| 英文摘要: |
| In order to improve the quality of degossypolized cottonseed protein, the existing problems in the production process of degossypolized cottonseed protein were analyzed, and the improvement scheme was put forward. The existing production technology of degossypolized cottonseed protein has the problems of high powder degree and high moisture content of cottonseed flake, and low KOH protein solubility of cottonseed protein. By separating the cottonseed kernel from the cottonseed kernel powder, adding a granulator to granulate the cottonseed kernel powder, and changing the discharge scraper of the dryer into a elevator, the powder degree was reduced. The moisture content in cottonseed flake was reduced by drying with air and steam simultaneously. Centrifugal separation technology was used to separate the degossypolized solution in the material so as to reduce the moisture content in the degossypolized solution, and then improve the KOH protein solubility of cottonseed protein. The quality of degossypolized cottonseed protein produced by the improved process is improved, the product quality is stable, the energy consumption in production is reduced, and the cost is saved. |
