实罐灭菌过程为什么要控制泡沫的产生?

这是因为过多的泡沫会引起罐内料液向轴封和排汽口外溢，可能引起污染；同时由于泡沫中汽泡传热较漫，会使发酵罐上部温度达不到灭菌规定温度，导致灭菌不彻底。

基于发酵罐优化的灭菌方式研究

讨论了在同样年生产能力条件下,发酵罐优化时灭菌方式的对比和选择。与40 m^3发酵罐相比,70 m^3发酵罐采用连续灭菌方式,可显著节约蒸汽和循环冷却水公用工程的消耗,同时也为缩短发酵周期提供了保证。

Heat Transfer Analysis of Sterilization of Canned Milk Using Computational Fluid Dynamics Simulations

A uniform and effective heat distribution inside the canned milk is very crucial for achieving effective sterilization. It is extremely difficult to establish the temperature profile inside the canned milk during continuous industrial scale operation. Computational fluid dynamics （CFD） simulation can be a useful tool to determine the temperature distribution of the fluid inside the can during the sterilization process. A CFD model was developed for the sterilization of canned milk at 121 ~C. The simulation results were validated with the experimental measurements of temperatures. The formation and movement of slowest heating zone （SHZ） during the sterilization process was tracked. Moreover, effect of can position （vertical and horizontal） during processing on milk temperature distribution inside the can was also investigated. Higher Grashof and Rayleigh numbers were obtained for vertical positioning of can compared to horizontal can processing. Further, effectiveness of the process was calculated based on F-value and these results reinforced the positive effect of horizontal position of can during the sterilization process.

P3级生物安全生产车间活毒废水处理系统的运行研究

由于P3级别生物安全生产车间内的工艺设备如生物反应器、隔离器、超滤浓缩、高压灭菌器等排出的废水具有一定的生物安全风险,导致其配套安装的活毒废水处理系统(灭菌罐)也应当有相应的生物安全防护措施。对活毒废水处理系统在实际工作中存在的风险点进行了详细的阐述,并根据风险点给出了具体的改进方案和建议。通过对活毒废水处理系统设计、安装及功能等方面的优化,配合辅助设施的使用,从而达到保障系统稳定运行、有效降低生物安全风险、保证疫苗生产人员及环境的安全性的目的。
