5. Dryer and Cooler

After granulation, the fertilizer granules are still moist and warm. The dryer reduces moisture content to 10–12%, while the cooler brings granules to ambient temperature for safe storage.

6. Screening Machine

A screening machine separates fine powder and oversized granules from the final product. This ensures that only uniform, high-quality granules are packaged.

7. Packing Machine

Finally, the packing machine automatically fills bags with the finished organic fertilizer and seals them for transportation. Advanced systems can also label, weigh, and palletize the product.

How an Organic Fertilizer Production Line Works

The production process can be divided into several key steps:

1. Raw Material Collection and Composting
   Organic waste is collected and fermented to create nutrient-rich compost. Microbial activity during composting breaks down organic matter while eliminating pathogens.

2. Crushing and Mixing
   Compost is crushed into smaller particles and blended evenly to ensure a balanced nutrient composition.

3. Granulation
   The mixed material is granulated into uniform pellets using a granulator. Granules are easier to store, transport, and apply.

4. Drying and Cooling
   Granules are dried to reduce moisture content, preventing spoilage, and then cooled to room temperature.

5. Screening and Packaging
   Oversized or undersized particles are removed, and high-quality granules are packed into bags for distribution.
