The production of bio organic fertilizers usually includes several main steps: raw material processing, fermentation, mixing, granulation, drying, and packaging. The following is a detailed process description:

1. Raw material pretreatment

Before producing bio organic fertilizers, the raw materials need to be crushed, crushed, and screened to achieve a particle size suitable for fermentation. Raw materials usually include organic substances such as animal manure, crop straw, and sludge.

2. Fermentation

Fermentation is the core step of the entire process. Send the preprocessed raw materials into a fermentation tank or perform aerobic fermentation through a turnstile. During the fermentation process, microorganisms decompose and transform organic matter to improve fertilizer efficiency. The commonly used fermentation equipment includes trough fermentation turners, crawler turners, and fermentation tanks, which ensure the uniformity and adequacy of the fermentation process through * * stirring and flipping.

3. Mixing

After fermentation, the raw materials need to be mixed with other fertilizer components to ensure uniform nutrient distribution. Common mixing equipment includes horizontal mixers and double shaft mixers, which can uniformly mix different ingredients to ensure the nutritional value of fertilizers.

4. Granulation

Granulation is a crucial step in turning fermented organic fertilizers into granules. The commonly used equipment includes flat die extrusion granulators, rotary drum granulators, and disc granulators, which are suitable for fertilizer production of different scales and types. The shape and size of the particles can be adjusted according to different needs.

5. Drying

After granulation, particles with high humidity still need to be dried by a dryer to ensure that the fertilizer is suitable for long-term storage and transportation. Drum dryer is commonly used in large-scale production and has the advantages of large processing capacity and low energy consumption.

6. Screening and packaging

After drying, the particles need to be screened out by a drum screening machine to obtain qualified particles, and the screened finished particles can be packaged by an automatic packaging machine. The packaging process ensures the quality and convenience of the product.
