摘　　要：由于血粉蛋白属于硬质蛋白,只有膨化加工方法才能使其血细胞膜全部破坏及血粉中硬质蛋白未充分变性,从而被动物消化吸收。为了提高血粉膨化机挤出血粉的质量(在对挤压过程进行了分析和研究的基础上),采用Smith预估PID控制,实现了对血粉膨化机各区温度控制。实验结果表明:该控制系统具有较优的动态控制性能,使用效果良好。In order to improve the quality of pushing out of blood meal through the blood meal extruder (on the basis of the thing that have carried on the analysis and research to the course of extrusion), adopt Smith to estimate PID to control in advance, has realized to every district temperature control of blood meal extruder. The experimental result indicates: this control system has more excellent controlling performance dynamically; the result of use is good.
