Embodiment 1
[0033] Such as Figure 1-4 Shown, a kind of production fermentation method of microbial fertilizer comprises the following steps:
[0034] S1 feeding, after adjusting the moisture content and carbon-nitrogen ratio of the microbial biomass raw materials and fertilizers, transport them into the feeding funnel 11;
[0035] S2 grinding, grinding and crushing a variety of microbial raw materials and fertilizers with different particle sizes, to a particle size range of 12mm-60mm;
[0036] S3 Mixed fermentation, send the ground and crushed microbial raw materials and fertilizers into the fermenter for fermentation, maintain the temperature within the range of 35-40°C, and continue to turn and ventilate;
[0037] S4 discharging, the fermented microbial fertilizer is discharged from the discharge pipe 22, and transported to the finished product area after being granulated and packaged;
[0038] The fermentation device used in the microbial fertilizer fermentation process includes a ...
Embodiment 2
[0046] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that: the grinding shell 1 is wound with a helical coil 6, the winding direction of the helical coil 6 is perpendicular to the direction of the magnetic induction line of the bar magnet 16, and the grinding shell 1 An electric heating wire 7 is embedded inside, and the electric heating wire 7 is coupled to the helical coil 6 .
[0047] In this embodiment, during the rotation of the bar magnet 16, the helical coil 6 continuously cuts the magnetic lines of the bar magnet 16 to generate an induced current, which supplies power to the heating wire 7, and preheats the microbial fertilizer in the grinding shell 1. , which shortens the heating cycle of the microbial fertilizer in the early stage of fermentation and improves the fermentation efficiency.
