Bio-organic fertilizer is actually made by inoculating microbial compound bacteria on the basis of the finished product of organic fertilizer. The difference is that a dissolving tank is added at the back end of organic fertilizer cooling and screening, and a puff bacteria coating machine can complete the whole process of bio-organic fertilizer production. Its production process and equipment: raw material fermentation preparation, raw material pretreatment, granulation, drying, cooling and screening, bacteria coating, packaging, tail gas purification treatment and other processes, and organic fertilizer production process and equipment are almost no different.
