Fermentation tank online sampling and diluting system and technology thereof

The invention relates to a fermentation tank online sampling and diluting system and a technology thereof. The fermentation tank online sampling and diluting system comprises a sampling system, a diluting system and a control system; the sampling system is connected with a reactor, through PLC automatic control, sampling is finished in the reactor, and filtering pretreatment is performed on a sample through a filter; after detection is finished, steam and sterile air can be introduced to perform cleaning and sterilization on the whole sampling system, so that the safe and stable running of thereactor is ensured; and the diluting system can dilute the sample in a detection range of a detection sensor and can run with high accuracy through switching of a valve. The system and the technologyprovided by the invention have the advantages of high safety, high automation degree, high accuracy and the like. 本发明涉及种发酵罐在线取样稀释系统及其工艺，它包括取样系统、稀释系统及控制系统；取样系统与反应器连接，通过PLC自动控制，从反应器中完成取样，并通过过滤器对样品进行过滤预处理。检测完后，可以通入蒸汽和无菌空气对整个取样系统
