Principle of making organic fertilizer composting
Organic manure compost turner is very important in the composting process, which has an important impact on the organic manure maturity and subsequent process. The composting principle of organic manure compost turner is to use the aerobic fermentation principle of organic manure composting, and use the organic manure compost turner to sprinkle the raw materials in the composting process, so that the raw materials can fully contact the oxygen in the air, so that the composting process can be fully fermented.
This is also the reason why organic fertilizer enterprises cannot process organic fertilizer without organic fertilizer compost turner. Judging from the maturity of organic fertilizer, the composted organic fertilizer is dumped by the compost turner to achieve harmless treatment, and the yield of organic fertilizer is higher.
1. Mixing function in raw material conditioning. In order to adjust the ratio of carbon to nitrogen, pH and water content of raw materials, some auxiliary materials should be added. The main raw materials and various auxiliary materials roughly piled together in proportion can be stirred by the compost turner to achieve the purpose of quenching and tempering.
2. Adjust the temperature of raw material stack. During the operation of the compost turner, the raw material aggregates are fully contacted and mixed with the air, and a large amount of fresh air can be contained in the material pile, which is conducive to the active production of fermentation heat by aerobic microorganisms.
3. Improve the permeability of the feedstock stack. The dumping system can process the material into small lumps, making the thick and dense material pile fluffy and elastic, forming appropriate porosity.
4. Adjust the moisture content of the raw material stack. The suitable moisture content of raw material fermentation is above or below 55%, and the moisture standard of finished organic fertilizer is below 20%.
5. Realize the special requirements of composting process. For example, the crushing of raw materials, giving a certain shape to the raw material pile or realizing the quantitative displacement of raw materials, etc.
