AI Technical Summary

Technical Problem

In the current citric acid production process, the raw materials do not react sufficiently in the fermentation tank and cannot be quantitatively added, resulting in poor fermentation effect.

Method used

An oxygen dissolving device was designed, comprising a fermenter, a stirring assembly, a storage assembly, and a sealing structure. The stirring assembly is driven by a motor to achieve quantitative feeding of raw materials, and the sealing ring and clamping block structure prevent oxygen leakage, ensuring a sufficient dissolved oxygen environment.

Benefits of technology

This method enables the quantitative addition and thorough mixing of raw materials, improving fermentation efficiency and quality. It also prevents oxygen leakage, ensuring stable dissolved oxygen levels in the fermenter and increasing citric acid production.
