摘　　要：为了提高糖化生产的的效率及品质,取代传统的手动或半自动糖化生产方式,针对糖化生产的特征,提出一种分步式糖化生产工艺流程,并设计出一种新型糖化控制系统。通过PID温控智能调节、变频器流量控制、调节物质在最适宜的糖化条件,使得不溶性物质在酶的催化下进行最优溶解。基于PLC和触摸屏建立糖化生产全过程的在线管理系统。该分步糖化提高了糖化产品的转化率,并提高了整体的生产效率,降低能耗。In order to improve the efficiency and quality of saccharification production, replace the traditional manual or semi-automatic saccharification production mode, this paper proposed a step-by-step saccharification production process, then designed a new saccharification control system, according to the characteristics of saccharification production. It made the insoluble substance dissolve optimally under the catalysis of enzyme, through PID temperature control intelligent regulation, frequency converter flow control, adjust the material in the most appropriate saccharification conditions. The online management system of the whole process of saccharification production was established based on PLC and touch screen. The step-by-step saccharification improved the conversion rate of saccharification products, improved production efficiency and reduced energy consumption.
