The invention belongs to the technical field of microbial
fertilizer production, and relates to a production
fermentation method of a microbial
fertilizer. The method comprises the following steps of:S1, feeding: carrying out
moisture content and
carbon nitrogen ratio adjustment on microbial raw materials and fertilizers, and conveying the microbial raw materials and the fertilizers into a feeding funnel; S2,
grinding:
grinding and crushing the plurality of microbial raw materials and fertilizers with different particle sizes until the particle size range is 12mm-60mm; S3, mixed
fermentation:feeding the ground and crushed microbial
biomass raw materials and fertilizers into a
fermentation tank for fermentation, maintaining the temperature within 35-40 DEG C, and continuously turning thematerials and fertilizers and performing ventilation; and S4, discharging: discharging the fermented microbial
fertilizer through a discharging
pipe, granulating, packaging, and transporting the fertilizer to a finished product area. According to the method of the invention, the vibration of a
grinding head can form a vibration effect on the fertilizer, promote the crushing of the fertilizer and improve the grinding efficiency; in the rotation process of a spiral
impeller, the mixing and exchange of the fertilizer at different positions are promoted, so that the fertilizer is in uniform contact with air, the turning effect is good, and the quality and fermentation efficiency of the microbial fertilizer are effectively improved.
