Fermentation tank online sampling and diluting system and technology thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of automatic on-line biochemical detection. Specifically, it is an online sampling and dilution system for a fermenter and its process for obtaining samples in the production process online in real time, and performing appropriate dilution, and finally performing detection and real-time feedback results. It is suitable for biochemical production. On-line detection of biochemical indicators. Background technique [0002] Process parameters in biochemical production are very important production indicators, which are related to the output and quality of the final product. Online detection technology can obtain a large number of required parameters in the production process, provide a basis for real-time control of the process, ensure the stability and controllability of technical parameters in the production process, and save a lot of labor in the production process. At the same time, with the enrichment of o...

Problems solved by technology

However, many biochemical parameters in the reaction process cannot be directly detected at present, mainly because the detection equipment cannot adapt to the environment of the reactor, or the concentration of substances in the reactor is not within the detection range of the equipment. Therefore, in the prior art, there are still many The biochemical parameters (such as reducing sugars, total sugars, organic acids, synthetic intermediates, etc.) cannot be detected in real time
