Method for preparing biological fertilizers from corn soaking liquid

利用玉米浸泡液制作生物肥的方法

Abstract

The invention relates to the field of agricultural and sideline product deep processing and particularly discloses a method for preparing biological fertilizers from corn soaking liquid. The method uses the corn soaking liquid as raw materials and is characterized in that the corn soaking liquid is concentrated, then, filter mud and alkali liquor are added for neutralization, the pH is regulated to 5 to 6, the corn soaking liquid is thrown into a mixed pre-fermentation device, crushed protein cake, filter mud and fiber slag are added into the fermentation device, and the pre-fermentation is carried out after the full mixing; then, an anaerobic fermentation device is adopted, biological species are added, and the fermentation is carried out again at 28 to 30 DEG C; and fermented products are added with ingredients, then, the drying, the granulation, the cooling and the screening are carried out, and then, products are obtained. The method has the advantages the environment pollution and the environment protection pressure are lightened, the corn soaking liquid and the filter mud of sugar refineries are effectively treated, new products are also developed, the nutrition and irrigation requirements of local farmers are met, and the effect of getting two results from one effort is reached.
本发明涉及农副产品深加工领域,特别公开了一种利用玉米浸泡液制作生物肥的方法。该方法以玉米浸泡液为原料,其特征在于:将玉米浸泡液浓缩后加入滤泥和碱液中和,调整pH值为5~6,将其投放到混合预发酵装置中,向发酵装置中添加粉碎好的蛋白饼、滤泥和纤维渣,充分混合后预发酵;然后采用厌氧发酵装置,加入生物菌种,在28~30℃下再次发酵;发酵后的产物经添加配料后经过烘干、造粒、冷却、筛分后得到产品。本发明既减轻了环境污染和环保压力,有效的处理了玉米浸泡液和糖厂滤泥,又开发新产品满足当地农户的营养和灌溉,一举两得。
