Description

Technical Field

[0001] The present invention relates to an organic fertilizer microbial fermentation system and method, belonging to the technical field of organic fertilizer production. Background Art

[0002] Microbial fermentation is the core technology for converting organic waste into high - efficiency fertilizers. Its essence is that microorganisms decompose organic matter through metabolic activities to achieve harmless treatment and nutrient conversion.

It includes side walls A and B arranged opposite to each other. A fermentation composting area is arranged between side walls A and B. A stirring - type bacterial liquid adding machine that travels along the length directions of side walls A and B is arranged on side walls A and B. The stirring - type bacterial liquid adding machine has a stirring roller for stirring materials and adding bacterial liquid. A bacterial liquid supply box body that moves along with the stirring - type bacterial liquid adding machine is arranged on the stirring - type bacterial liquid adding machine. The present invention has the following beneficial effects: The bacterial liquid is sprayed out through a nozzle. The traveling trolley is started, and the traveling trolley moves along the length direction of the fermentation composting area. While turning the materials with rotary tillage teeth, the bacterial liquid is added to the materials, realizing uniform addition of the bacterial liquid, further accelerating the mixing rate of the bacterial strain and the organic matter, and thus improving the quality of the biological organic fertilizer after production.
