Generally speaking, the complete equipment of chicken manure organic fertilizer production line is mainly composed of fermentation system, drying system, deodorization and dust removal system, crushing system, batching system, mixing system, granulation system, screening system and finished product packaging system. The fermented and decomposed chicken manure is sent to the crusher for crushing, and the fineness of 80 mesh materials accounts for more than 65%. It is sent to the organic raw material warehouse through the conveyor belt. After electronic measurement, it enters the raw material grinder together with other raw materials (nitrogen, phosphorus and potassium) for secondary crushing and mixing. The crushed and mixed materials are sent to the drum granulator through the belt conveyor. In the drum granulator, the materials are added with water and steam In this case, the raw material temperature is raised, and the viscosity of the material is excited. Under the continuous rolling of the drum granulation, the material gradually rolls into a ball, and is sent to the dryer through the belt conveyor. The hot air in the hot blast stove is introduced into the dryer through the induced draft fan, which fully contacts with the organic fertilizer particles entering the dryer. The moisture in the particles is quickly exchanged, and a large amount of water vapor is driven by the induced draft fan It is introduced into the dust drop chamber and emptied after dust removal and water washing.

After drying, the temperature of the dried particles is about 70 degrees, which flows out through the tail of the dryer, and then enters the cooler for cooling. The normal temperature air introduced by the induced draft fan fully contacts with the high-temperature particles in the cooler. The temperature of the high-temperature particles is gradually cooled to the normal temperature. The hot and humid air in the cooler is introduced into the dust drop chamber by the induced draft fan, and then discharged after dust removal and water washing. The organic fertilizer particles cooled to normal temperature flow out from the tail of the cooler and enter the screening machine. Under the continuous rolling action of the screening machine, the unclassified organic fertilizer successively passes through the fine screen section and the finished product screen section of the screening machine. The organic fertilizer is divided into three specifications: fine return material, finished product particle and large particle. The fine return material and the crushed large particle are returned to the granulator through the return belt conveyor After re granulation, the finished product particles are sent into the coating machine through the belt conveyor, and fully contact and mix with the coating oil or functional bacteria that are metered into the coating machine. The coated oil or functional bacteria are evenly wrapped and absorbed on the surface of organic fertilizer particles, and then enter the finished product warehouse. After being measured by the electronic metering packaging machine, they are sent to the packaging machine for packaging and sealing, and then enter the finished product storage.
