The cow manure organic fertilizer turning machine is a key equipment that converts organic waste such as cow manure into high-quality organic fertilizer. Through biological fermentation technology, it decomposes organic matter and concentrates nutrients. The following are the specific working principles and processing steps:
working principle
The cow manure organic fertilizer turning machine is based on the principle of aerobic fermentation, using microorganisms to decompose organic matter under suitable temperature, humidity, and oxygen conditions, producing heat and carbon dioxide. This process is called “composting”. The machine regularly flips the compost pile to provide sufficient oxygen, accelerate microbial activity, and promote rapid degradation of organic matter.
Processing steps
Raw material collection and pretreatment: Collecting fresh or stored cow manure for a period of time generally requires crushing, screening, and removing large impurities. Sometimes, a certain amount of auxiliary materials such as straw, sawdust, and husks need to be added to adjust the carbon nitrogen ratio and promote microbial growth.
Moisture regulation: The moisture content of cow manure should be controlled at around 50% -60%, as too high or too low can affect the fermentation effect. If there is insufficient moisture, it is necessary to spray an appropriate amount of water; If there is too much water, measures need to be taken to dehydrate.
Stacking fermentation: Pre treated cow manure is stacked into a pile of a certain height and width, and the turning machine is started for initial stacking. At this time, bacterial strains can be added to accelerate the fermentation speed.
Pile turning ventilation: Use an organic fertilizer turning machine to regularly turn over the compost pile, ensuring sufficient oxygen and dissipating the generated heat, maintaining the ideal fermentation temperature (usually 50 ° C-60 ° C), and accelerating water evaporation to promote microbial activity.
Secondary fermentation and maturation: After the first turning of the compost pile, continue to observe the temperature changes inside the pile, and if necessary, turn the pile again until the compost is completely mature, usually taking several weeks. During this period, cow manure will gradually turn dark brown and the odor will become lighter.
Post processing: Fermented and matured organic fertilizers need to be screened to remove undecomposed large chunks, further dried to achieve the desired moisture content (about 10% -15%), and then packaged for storage.
Quality testing: Finished organic fertilizers must undergo quality testing by professional institutions to confirm that pH value, nutrient content, pathogen and other indicators are qualified before they can be put on the market.
The cow manure organic fertilizer turning machine not only processes a large amount of agricultural production waste, reducing environmental pollution, but also produces organic fertilizers rich in beneficial microorganisms and organic matter, improving soil structure, increasing crop yield and quality, and is an important component of agricultural circular economy and sustainable development.
