Organic fertilizer composter is the core equipment of aerobic dynamic composting. As a new type of machinery, it is unknown in the national product catalog, but it has rapidly multiplied in the fertilizer machinery and equipment family, becoming a tool to replace manual and forklift dumping, and is the mainstream product that affects the development trend of the composting industry. The importance of organic fertilizer composter stems from its role in composting production:
- Mixing effect in raw material conditioning
In order to adjust the carbon nitrogen ratio, pH and water content of raw materials, some auxiliary materials must be added to the compost. The main raw materials and various auxiliary materials are roughly stacked together in proportion, which can be evenly mixed by the dumper to achieve the purpose of tempering.
- Adjust the temperature of the raw material pile
During the operation of the stacker, the raw material particles fully contact and mix with the air, so that a large amount of fresh air can be stored in the material stack, which is conducive to the active production of fermentation heat by aerobic microorganisms and the improvement of the stack temperature; When the temperature is high, adding fresh air can reduce the chimney temperature. The state of medium temperature high temperature medium temperature high temperature alternation is formed, and various beneficial microorganisms are rapidly growing and reproducing in the temperature range suitable for beneficial microorganisms.
- Improve the permeability of raw material pile
The turnover system can process the materials into small pieces, making the thick and dense raw material pile fluffy and elastic, forming appropriate pores.
- Adjust the water content of the raw material pile
The suitable water content of raw material fermentation is above 55%, and the water content of finished organic fertilizer is below 20%. In the process of fermentation, new water will be produced by biochemical reaction, and the consumption of raw materials by microorganisms will cause the water to lose its carrier and become free. Therefore, the water content will decrease in time with the fertilizer making process. In addition to the evaporation caused by heat conduction, the turning of raw materials by the organic fertilizer composter will also cause forced water vapor emission.
- Special requirements for composting process
For example, crushing raw materials, giving a certain shape to the raw material pile or realizing quantitative replacement of raw materials.
