The process flow of organic fertilizer production line mainly includes steps such as raw material preparation, fermentation, post-treatment (such as granulation, drying, cooling, screening, etc.), and packaging. Below is a detailed description of this process:

1. Raw material preparation and pretreatment

Collection and classification: Firstly, collect various organic wastes such as livestock and poultry manure, crop straw, food processing residues, etc., and conduct preliminary classification.

Crushing and mixing: Use a crusher to crush large pieces of raw materials to a particle size suitable for fermentation, and then mix the raw materials in a certain proportion to optimize the carbon nitrogen ratio and promote fermentation.

2. Fermentation

Composting fermentation: The pre treated raw materials are sent to the composting fermentation area, and through a natural or artificially controlled high-temperature fermentation process, microorganisms are used to degrade organic matter while killing pathogens and weed seeds. During the fermentation process, it is necessary to regularly flip the pile to provide sufficient oxygen and control the temperature.

Fermentation control: By monitoring temperature, humidity, and oxygen levels, adjust fermentation conditions to ensure an efficient and stable fermentation process.

3. Post processing

Screening and crushing: After fermentation, organic matter may need to be screened and crushed again to remove undecomposed impurities and ensure the uniformity of the raw materials.

Granulation: Use an organic fertilizer granulator to turn fermented organic matter into granules, improving the storage and usability of fertilizers.

Drying: Granular organic fertilizers need to be dried to remove excess moisture and prevent clumping during storage.

Cooling: The dried fertilizer needs to be cooled to room temperature to prevent high temperatures from affecting the quality of the fertilizer.

Screening: Re screen fertilizer particles to ensure consistency in product particle size.

Coating (optional): Apply a thin film on the surface of fertilizer particles to improve moisture resistance and control nutrient release rate.

4. Packaging

Automatic packaging: Use an automatic packaging machine to weigh and package finished organic fertilizers, forming packaging bags that are easy to transport and sell.

5. Quality inspection and storage

Quality testing: Conduct quality testing on finished organic fertilizers to ensure compliance with relevant standards and regulations.

Storage and transportation: Qualified organic fertilizers are stored in dry and ventilated warehouses, waiting for further sales or transportation.

Through the above process flow, the organic fertilizer production line can convert various organic wastes into high-quality organic fertilizers, not only solving the problem of waste disposal, but also providing sustainable fertilizer resources for agriculture and promoting the green development of agriculture.
