The simplest small-scale organic fertilizer production line usually includes the following types of equipment:

Fermentation equipment: used for composting and stacking, effectively mixing viscous stored feces with microbial agents and straw powder. This equipment not only has a fast fermentation rate, but also effectively prevents the generation of harmful odorous gases during the fermentation process, which meets environmental protection requirements.

Organic fertilizer crusher: used to better crush fermented materials and lay a solid foundation for the next process.

Organic fertilizer mixer: used for mixing formula fertilizers and adding various substances such as nitrogen, phosphorus, potassium, humic acid, etc.

Granulator: mainly used for granulation, mixed materials are uniformly fed into the granulator through a conveyor for deep granulation.

Drying machine: mainly plays a role in volatile material moisture. Due to the large amount of water in the granulation process of the granulator, the particles cannot be immediately packaged after production and require drying equipment to evaporate water.

Cooling machine: Due to the high temperature of the dry material, the particles cannot be immediately packaged, and the material temperature needs to be quickly reduced to a constant temperature through the cooler.

Screening machine: mainly used for separation, distinguishing finished particles from inferior products, and returning defective products for granulation.

Automatic packaging machine: mainly plays the role of automatic packaging, weighing, and sewing.

The above equipment may vary depending on the configuration and scale of the production line, but they are all basic components of small-scale organic fertilizer production lines. When selecting equipment, factors such as raw material characteristics, production needs, and budget should be considered.
