Recent Progress of Commercially Available Biosensors in China and Their Applications in Fermentation Processes

Biosensors, which are the products of the biotechnology industry, are among the key projects of the 7th, 8th, and 9th Fiveyear Plans of China Science ＆ Technology Developing Programs, respectively, and they play an important role in developing and reforming traditional biotechnology. SBA series biosensor analyzer, as the only one commercial biosensor in China, has attracted lots of attention in the process of information gathering and measurement for biological industry with the development of technology and society. In this paper, we presented an overview of the most important contributions dealing with the monitoring of the biochemical analytes in fermentation processes using SBA series biosensor analyzers in China. Future trends of the biosensor analyzer in China were also mentioned in the last section.

水泥粉磨智能优化控制系统的应用

中材邦业(杭州)智能技术有限公司开发的水泥粉磨智能优化控制系统,采用一键启停技术、基于预测模型控制的先进控制技术和在线粒度分析仪,三者的有机结合,真正实现了水泥粉磨全过程、全工况、无人值守的自动化控制。水泥粉磨智能优化控制系统的实施,使系统能在最经济和最优化的参数下运行,系统启动时间由原来的10～15min缩短到5min,明显改善水泥磨系统工况,稳流仓波动的标准偏差降低70%以上,45μm筛筛余的标准偏差由0.97降低为0.75,比表面积合格率100%,三大主机设备平均电耗降低1.1k Wh/t水泥。
