棉籽仁壳分离系统改造实践Modification practice of cottonseed kernel husk separation system

Abstract

传统的棉籽仁壳分离系统存在仁壳分离效果不佳，进而影响棉籽蛋白产品中蛋白质含量的问题，为此对传统棉籽仁壳分离系统进行了改造。通过对剥壳前光棉籽进行调质处理，优化仁壳分离工艺，可将棉仁含壳率由10%～15%降至2%～4%，棉壳含仁率由0.5%～0.8%降至0.1%～0.3%，通过浸出（脱脂脱酚）后可得到蛋白质含量为60%～65%的棉籽蛋白产品。The traditional cottonseed kernel husk separation system has the problem of poor separation effect, which affects the protein content in cottonseed protein. Therefore, the traditional cottonseed kernel husk separation system was modified. Through the conditioning treatment of cottonseed before hulling and the optimization of the separation process of kernel husk separation, the content of husk in kernel can be reduced from 10%-15% to 2%-4%, the kernel content in husk can be reduced from 0.5%-08% to 0.1% - 0.3%, and the cottonseed protein products with protein content of 60%-65% can be obtained after defatting and degossypol.
