Harmless treatment of cow manure. Harmless treatment of manure. The process of cow manure organic fertilizer production line
in the farm is to use scientific methods to kill or remove pathogenic microorganisms and parasitic eggs in the manure. The feces can meet the requirements of harmless sanitation standards. At present, the harmless treatment methods of manure commonly used in farms include high-temperature composting and the establishment of biogas digesters as raw materials for biogas production. But more is still collected and used as farm manure to return to the field.
The technology of the cow manure organic fertilizer production line is advanced. Livestock and poultry manure is treated with harmless live bacteria preparations, and biological fermentation is carried out under the action of a variety of beneficial microorganisms. After fully decomposing the organic matter in it, the nutrients are released, and the resulting biological heat and high temperature The fermentation process can kill germs, insect eggs, detoxify and deodorize, purify the environment, achieve harmless, resource and industrialization, low energy consumption and stable product quality.
Process flow of cow manure organic fertilizer production line
Cow manure processing commercial organic fertilizer requires two steps: pre-fermentation and processing part and deep processing granulation part. The supporting equipment for organic fertilizer requires fermentation turning machine, crusher, screening machine, mixer, fertilizer granulator machine
, dryer, cooler, screening machine, coating machine, packaging machine, conveyors and other equipment.
- 1. The recovered livestock and poultry manure directly enters the fermentation area. After one fermentation and two aging stacks, the odor of livestock and poultry manure is eliminated. At this stage, fermenting bacteria can be added to decompose the crude fiber, so that the particle size requirements after crushing meet the particle size requirements of the fertilizer granulator machine.
- 2. Crushing the fermented material after completing the second aging and stacking process, and enter the mixing mixer. Before mixing and mixing, according to the recipe, add N, P, K and some other trace elements to the mixing mixer to start mixing.
- 3. Transfer the mixed materials to the fertilizer granulator machine, granules pass through the dryer and enter the cooling machine, the materials will be sieved after reaching normal temperature, and the particles that meet the requirements will enter the coating machine to wrap the coating film and begin to pack, which does not meet the requirements After the granules are crushed by the crusher, they are returned to the granulation system and continue to granulate.
- 4. Finished products are automatically packaged.
