The Secrets of Bio-Organic Fertilizer Production Lines

The bio-organic fertilizer production line is the core vehicle for transforming agricultural waste into high-quality fertilizer. Its production process requires scientific proportioning and precise processing to ensure the fertilizer is both nutritious and active.

The first step in production is raw material pretreatment. Workers transport raw materials such as livestock and poultry manure, straw, and mushroom residue to the workshop, where they are sorted to remove impurities. A crusher then pulverizes the straw and other coarse fiber materials to 2-5 mm. An automatic batching system then automatically mixes the various raw materials according to the optimal carbon-nitrogen ratio of 30:1 and adds composting agents, laying the foundation for subsequent fermentation.

The second step is the high-temperature aerobic fermentation stage. The mixed raw materials are fed into a fermentation tank or vat, where the fermentation system continuously controls temperature, humidity, and oxygen content. The temperature initially rises to above 55°C to kill insect eggs and pathogens; in the middle, it is maintained at 60-70°C to promote microbial decomposition of organic matter; and in the later stages, the temperature gradually decreases to form stable humus. The entire process takes approximately 7-15 days, during which time a compost turning machine turns the fertilizer every 2-3 days to ensure even fermentation.

After fermentation is complete, the material enters the advanced processing stage. A drum screener separates the uncomposted coarse material (which returns to the fermentation stage). Qualified material is then fed into a granulator (such as a rotary drum granulator or a new type organic fertilizer granulator). Depending on market demand, it can be produced in various forms, such as granules or powders. The granular fertilizer needs to go through a drum fertilizer dryer to reduce the moisture content to below 15%, and then pass through a drum cooler to cool it to room temperature to prevent clumping.

Finally, the finished product is processed and tested. After cooling, the fertilizer is coated with a probiotic agent in a film coating machine to improve its effectiveness and stability. It is then weighed and packaged. Quality inspection departments will sample and test the fertilizer for indicators such as organic matter content and effective viable bacterial count. Only products that meet national standards are labeled and shipped to farmland, providing green energy for crop growth.
