Pig manure organic fertilizer products can be produced in pellet or powder form, depending on market demand. To ensure balanced nutrients, facilitate transportation, and improve storage, it is recommended to process organic-inorganic compound fertilizers into pellet products. The pellet shapes include cylindrical and spherical. The finished products moisture content requirements are: organic fertilizer ≤20%; organic-inorganic compound fertilizer ≤10%.

  The pig manure organic fertilizer production line is a series of production equipment that uses pig manure as raw material, fermented and processed through high-tech devices to produce organic fertilizers.

  The processing of pig manure into commercial organic fertilizer involves two steps: the preliminary fermentation and treatment phase, and the deep processing granulation phase. The required equipment includes a fermentation turner, organic fertilizer crusher, drum screening machine, horizontal mixer, disc granulator, rotary dryer, cooling machine, screening machine, coating machine, packaging machine, and conveyor.

  The production process of pig manure organic fertilizer is as follows:

① Raw material fermentation --- ② Raw material automatic weighing and batching by computer belt scale --- ③ Crushing and mixing --- ④ Flat die granulation, stirring tooth granulation, extrusion granulation --- ⑤ Drying machine: Drying organic fertilizer pellets --- ⑥ Cooling machine: Cooling organic fertilizer pellets --- ⑦ Sieve machine screening out qualified organic fertilizer pellets --- ⑧ Coating machine coating the pellets for smoother surface --- ⑨ Packing scale automatically filling organic fertilizer pellets --- ⑩ Sealing

The utility model pertains to the technical field of organic fertilizer production equipment, specifically an organic fertilizer production line, which sequentially includes a crusher, fermentation tank, granulator, dryer, cooling machine, coating machine, screening machine, and packaging and metering machine. The fermentation tank consists of two sidewalls and a base plate, with a temperature control system installed on the exterior. Holes are arranged on the two sidewalls, each housing an extensible rod that extends from inside to outside the fermentation tank. The end of the extensible rod inside the tank is equipped with a conical head, and a temperature sensor is mounted on the conical head, connected to the temperature control system outside the tank. The granulator features a circulating conveyor belt driven by transmission wheels, with a pressure plate mounted above the belt. One end of the pressure plate has a feed pipe inclined at an angle, and the surface of the conveyor belt is fitted with a perforated plate arranged in a honeycomb pattern. This utility model boasts high automation and can swiftly meet the requirements of organic fertilizer production.
