Abstract

The invention relates to a fermentation device for the continuous bio-fermentation of D-lactic acid. The device comprises a fermenting tank, a feeding system and a discharging system, the feeding system and the discharging system are respectively connected with the fermenting tank, the feeding system can supplement a fresh sterile medium into the fermenting tank; and the discharging system comprises a solid-liquid separator, a bacterial liquid collecting bottle, a thallus collecting bottle, a first peristaltic pump, a second peristaltic pump, a third peristaltic pump, a fourth peristaltic pumpand a connecting pipeline. The device can realize the continuous fermentation of D-lactic acid, is simple to operate, effectively ensures the fermentation quality, greatly improves the production efficiency of the D-lactic acid, and is not prone to cause pollution; and a strain can be recycled and reused, so the production cost is saved, and convenience is brought for use.

Description

technical field [0001] The invention belongs to the technical field of fermentation equipment, in particular to a fermentation device for continuous biological fermentation of D-lactic acid. Background technique [0002] At present, in the fermentation production process of D-lactic acid, it is mainly fermented in a single batch of tanks. After the fermentation is completed, the fermentation liquid needs to be put into the tank once for subsequent extraction. After the fermentation liquid is released, the fermentation tank needs to be cleaned again. The fresh fermentation medium should be sterilized by high temperature and the initial pH value of the fermentation medium in the fermenter should be adjusted. The D-lactic acid bacteria culture in the previously cultivated secondary seed tank should be in place and have the fermentation inoculation. In the process of inoculating the mature seed liquid into the fermenter, the operation process is complicated, and the strains are ...
