As a new type of machinery, the organic fertilizer composter is still unknown in the national product catalogue, but it has rapidly multiplied in the fertilizer machinery and equipment family, becoming a tool to replace the manual and forklift tipping, and is the mainstream product affecting the development trend of the compost industry. Organic fertilizer composter is the core equipment of aerobic dynamic composting, and its importance stems from its role in composting production:
- Mixing effect in raw material conditioning
In order to adjust the C/N ratio, pH and water content of raw materials, some auxiliary materials must be added into the compost. The main raw materials and various auxiliary materials are roughly stacked together in proportion, and can be mixed evenly through the stacker to achieve the purpose of tempering.
- Adjust the temperature of raw material pile
During the operation of the organic fertilizer composter, the raw material particles are fully mixed with the air, so that a large amount of fresh air can be stored in the material pile, which is conducive to the active generation of fermentation heat by aerobic microorganisms and the increase of the pile temperature; When the temperature is high, adding fresh air can reduce the chimney temperature. It forms a state of medium-high temperature-medium temperature-high temperature alternation, and various beneficial microorganisms grow and multiply rapidly in the temperature range suitable for beneficial microorganisms.
- Improve the permeability of raw material pile
The tipping system can process the materials into small pieces, making the thick and dense raw materials bulky and elastic, and forming appropriate pores.
- Adjust the water content of raw material pile
The suitable water content of raw material fermentation is above 55%, and the water content standard of finished organic fertilizer is below 20%. In the fermentation process, biochemical reaction will produce new water, and the consumption of raw materials by microorganisms will lead to the loss of carrier and dissociation of water. Therefore, the water content will decrease in time with the fertilizer making process. In addition to the evaporation formed by heat conduction, the overturning of raw materials by the tipper will also form forced water vapor discharge.
- Special requirements for composting process
For example, crushing raw materials, giving raw materials a certain shape or realizing quantitative replacement of raw materials.
The organic fertilizer composter is mainly applicable to farms of various scales, and its application value is worthy of affirmation. The production of organic fertilizer in the fermentation tank mode is to place raw materials in the fermentation tank, and the materials will be overturned, stirred and broken in the tank, so that the materials can be fermented, matured and degraded. It is easier to obtain stable product performance than static compost, and the odor control effect is better.
