Dynamic pipeline fermentation device and fermentation method

Abstract

The invention relates to a dynamic pipeline fermentation device and a fermentation method. According to the fermentation device, a buffer tank of a fermentation module unit is provided with a buffer tank feeding port, a buffer tank discharging port and a buffer tank exhaust port; a venturi spray device includes a spray device feeding port, a spray device discharging port and a spray device air inlet; the buffer tank feeding port is communicated and connected with a feeding pipeline, the buffer tank discharging port is communicated and connected with the spray device feeding port through a pipeline, the buffer tank exhaust port is communicated and connected with a sterile filter through a pipeline, the spray device discharging port is communicated and connected with a material pipeline, thematerial pipeline is communicated and connected with the buffer tank feeding port and a discharging pipeline, and the spray device air inlet is communicated and connected with a sterile gas pipelineor a saturated steam pipeline through a pipeline. The dynamic pipeline fermentation device not only can carry out sufficient gas-liquid mixing, but also can promote good flow of materials in the pipeline by utilizing turbulence effect of jet flow at the spray device discharging port, and the fermentation module unit can be used singly or in multi-stage series connection.

Description

technical field [0001] The invention relates to the technical field of biological fermentation equipment, in particular to a dynamic pipeline fermentation device and a fermentation method. Background technique [0002] Generally, the fermentation devices used in production are mainly mechanical stirring type fermentation devices and air lift type fermentation devices, which require a large amount of equipment investment and high requirements for installation space. [0003] The mechanical stirring fermentation device is characterized by a complex structure, which requires a stirring container and a mixer to be used together. The gas enters from the bottom of the stirring container, and drives the stirring shaft and the stirrer through the transmission device to break the rising bubbles into smaller bubbles; the selection of the stirrer affects the circulation effect and stirring power, which in turn affects the gas-liquid mixing efficiency and the dissolved gas volume .

AI Technical Summary

Problems solved by technology

The air-lift fermentation device is generally slender, with a large height-to-diameter ratio, high requirements for installation three-dimensional space, and a single production mode; it requires a very large air throughput; the mixing contact between phases is poor; when the circulating organic matter and operating conditions change The substrate, nutrients and dissolved oxygen cannot be kept consistent; it is not suitable for fermentation of high-viscosity culture liquid, fermentation of culture liquid containing a large amount of solids, high-density culture fermentation, etc.
