摘　　要：在搭建了啤酒发酵实验装置的基础上,采用有限差分法分析了发酵罐罐内温度场分布,建立了壁面温度T0和发酵罐内0.2 m处温度T0.2间关系的知识库,将此知识库用于发酵温度无菌化测量,并将遗传算法用于发酵温度PID控制参数的优化.经实验证明,这种方法为满足纯生啤酒无菌化生产提供了一种可行的途径.In this paper, we established a beer fermentation experimental device,analyzed the temperature field distribution in the fermentation tank with the finite difference method. The knowledge database of the relationship between the measurement parameter T0（wall temperature） and the target parameter To.2 （the temperature within the fermentation tank in 0.2 m from the wall） was established, which was effectively applied to the germfree measure of fermentation temperature and achived a satisfactory result. GA is used in the parameter optimization of fermentation temperature PID. The experiment results illustrate that this method can meet the demand of germfree production in draft beer.
