1. , a kind of first granulation, secondary fermentation utilize organic waste to make the novel process of granular biological fertilizer, it is characterized in that, and first granulation, stoving process is exempted from secondary fermentation, and it mainly is to finish by following steps:

  • (1) proportioning raw materials;

    make it reach best granulation, fermentation condition;

    In A, the waste, organic content is between 40-80%B, moisture content are controlled between the 50-30%C, C/N ratio is controlled between the 25-35%The phosphorus ore containing matter of D, adding about 5%E, pH value are controlled between the 6.5-8The microorganism quick rotting agent of F, adding 1-2 ‰

    (2) with joining raw material send into and carry out broken granulation in the granulating disc that has shredder assembly, make the particle of desired size.(3) the bright fertile aerobic fermentation of piling up of the particle that will make.(4) control its leavening temperature, the temperature of utilizing its fermentation to produce is with the water evaporates in the compost.(5) drop to normal temperature when compost temperature, section has a large amount of white hyphas, and moisture content has just been finished the manufacturing processed of bio-fertilizer 20% when following.
