一种花生水溶肥发酵装置及其发酵方法
By introducing a stirring and aeration mechanism into the peanut water-soluble fertilizer fermentation device, the residence time of air bubbles is extended, promoting oxygen dissolution and uniform distribution of peanut bran. This solves the problems of low oxygen dissolution efficiency and peanut bran deposition in existing technologies, improves fermentation efficiency, and reduces energy consumption.

AI Technical Summary
In existing peanut water-soluble fertilizer fermentation devices, the air stays in the fermentation liquid for a short time, resulting in low oxygen dissolution efficiency. Furthermore, peanut bran is prone to sedimentation and agglomeration, leading to uneven fermentation, increased energy consumption, and fermentation heat loss.
The system employs a stirring mechanism and a gas distribution mechanism, including spiral blades and a gas dispersion device. The rotation of the spiral blades and the design of the injection nozzle extend the residence time of bubbles in the fermentation broth. The design of the airflow guide and the circular tube promotes bubble breakage and uniform distribution, preventing peanut bran from settling.
It improves the dissolution efficiency and utilization rate of oxygen, achieves uniform distribution of peanut bran, increases the contact area between fermentation liquid and air, improves fermentation efficiency, and reduces energy consumption and fermentation heat loss.
