Sampling device for microbial fermentation liquor

Abstract

The invention discloses a sampling device for microbial fermentation liquor. The sampling device comprises a bottom plate, a lifting unit and a sampling unit. A supporting plate is arranged on the left side of the upper surface of the bottom plate and is in an L shape, and the middle of the lower surface of the bottom plate is fixedly connected with the upper surface of a limiting barrel. The lifting unit comprises a fixing plate, a lifting rod, an electric push rod and a sampling tank, the lower end of the electric push rod is fixedly connected with the right side of the upper surface of thebottom plate, the upper end of the electric push rod is fixedly connected with the right side of the lower surface of the fixing plate, and the left side of the lower surface of the fixing plate is fixedly connected with the upper end of the lifting rod. The lower end of the lifting rod penetrates through the middle of the upper surface of the bottom plate and is fixedly connected with the middleof the upper surface of the sampling tank, and the side face of the sampling tank is connected with the inner side face of the limiting barrel in a sliding mode. According to the sampling device for the microbial fermentation liquor,sampling height can be adjusted, sampling can be carried out at all height positions in the fermentation tank, and the judement accuracy of the fermentation conditionof raw materials by people is improved.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation equipment, in particular to a sampling device for microbial fermentation liquid. Background technique [0002] Microbial fermentation refers to the process of using microorganisms to transform raw materials into products needed by humans through specific metabolic pathways under suitable conditions. The production level of microbial fermentation mainly depends on the genetic characteristics and culture conditions of the strain itself. Fermentation engineering Scope of application Pharmaceutical industry, food industry, energy industry, chemical industry, agriculture: genetic modification of plants; biological nitrogen fixation; engineering insecticide biopesticides; microbial nutrients, environmental protection, etc. During the microbial fermentation process, continuous sampling is required. Both monitor the fermentation process, but most of the existing sampling devices use samplin...

[0002] Microbial fermentation refers to the process of using microorganisms to transform raw materials into products needed by humans through specific metabolic pathways under suitable conditions. The production level of microbial fermentation mainly depends on the genetic characteristics and culture conditions of the strain itself. Fermentation engineering Scope of application Pharmaceutical industry, food industry, energy industry, chemical industry, agriculture: genetic modification of plants; biological nitrogen fixation; engineering insecticide biopesticides; microbial nutrients, environmental protection, etc. In the process of microbial fermentation, continuous sampling is required. Both monitor the fermentation process, but most of the existing sampling devices use sampling valves for sampling. The sampling valve can only sample at a fixed position in the fermenter. The position of the sample taken out is fixed and cannot be accurately taken to the fermenter. Samples at various heights in the interior allow people to make accurate judgments on the fermentation of raw materials
