Automated organic fertilizer granulation lines, as integrated production systems that integrate multiple processes, have become the core equipment for organic fertilizer enterprises, realizing full-process automation from raw material pretreatment to finished product packaging. The factory direct supply model of these production lines eliminates intermediate links, bringing higher cost-effectiveness and more reliable quality assurance to users. This article provides a detailed introduction to automated organic fertilizer granulation lines, including their overall overview, core process flow, key equipment configuration, advantages of factory direct supply, application scope, operation and maintenance, helping users fully understand the value and application of this integrated production line.

Overview of Automated Organic Fertilizer Granulation Line

An automated organic fertilizer granulation line is a complete set of integrated production equipment designed specifically for the large-scale production of organic fertilizer. Different from single granulation equipment, it integrates multiple functional links such as raw material crushing, fermentation, mixing, granulation, drying, cooling, screening, and packaging, realizing full-process automated operation with minimal manual intervention.

The core positioning of this production line is "automation" and "factory direct supply". Automation is reflected in the intelligent control of the entire production process, which can accurately control parameters such as fermentation temperature, granulation size, and drying moisture, ensuring stable product quality and high production efficiency. Factory direct supply means that the production line is produced and supplied directly by the manufacturer, eliminating intermediate distributors and agents, which not only reduces the purchase cost for users but also ensures the consistency of equipment quality and provides direct after-sales support. It is widely used in organic fertilizer production enterprises, large-scale agricultural cooperatives, and environmental protection projects that realize organic waste resource utilization.

Core Process Flow of Automated Organic Fertilizer Granulation Line

The automated organic fertilizer granulation line follows a scientific and standardized production process, with each link closely connected and fully automated, ensuring the efficiency and quality of organic fertilizer production. The specific process flow is as follows:

1. Raw Material Pretreatment

Raw material pretreatment is the foundation of organic fertilizer production, mainly to process raw materials such as livestock and poultry manure, crop straw, food processing waste, and garden waste into a state suitable for fermentation and granulation. The pretreatment link includes crushing, sorting, and dehydrating. The automated crusher crushes large-volume raw materials into fine particles, increasing the contact area between raw materials and beneficial microorganisms; the sorting device removes impurities such as stones and plastic; the dehydrator adjusts the moisture content of raw materials to 50%-60%, avoiding anaerobic fermentation and odor pollution.

2. Automated Fermentation

Fermentation is the core link of organic fertilizer production, which converts raw organic materials into stable, non-toxic organic matter through the decomposition of beneficial microorganisms. The automated fermentation system is equipped with a trough-type or closed fermentation tank, with automatic temperature control, oxygen supply, and stirring functions. The system can accurately control the fermentation temperature between 55-70℃, ensuring the full decomposition of organic matter and killing pathogens, insect eggs, and weed seeds. The fermentation process is fully automated, and the system automatically adjusts the stirring frequency and oxygen supply according to the temperature change, shortening the fermentation cycle to 15-30 days.

3. Automated Batching and Mixing

After fermentation, the organic material is transported to the batching and mixing system. The automated batching system uses high-precision electronic scales to accurately weigh the fermented base material, trace elements, and beneficial microbial agents according to the preset formula, with small measurement errors. The weighed materials are automatically transported to the mixer, which fully mixes the materials to ensure that trace elements and beneficial microorganisms are evenly distributed, laying the foundation for high-quality granulation.

4. Automated Granulation

The mixed materials are transported to the automated granulation equipment, which converts the powdery materials into spherical granules with uniform size and high strength. The common granulation equipment in the production line includes disc granulators and drum granulators, which are linked with the control system to automatically adjust the granulation speed and binder spray amount according to the material characteristics. The particle size can be flexibly adjusted between 2-8mm to meet different application needs.

5. Drying and Cooling

The granular products after granulation contain a lot of moisture, which needs to be dried and cooled to ensure storage stability. The automated drying equipment adopts low-temperature hot air drying technology to avoid the loss of organic nutrients and beneficial microorganisms. The drying temperature and time are automatically controlled by the system, reducing the moisture content of the particles to ≤15%. The cooled particles are then transported to the cooler, which quickly cools the particles to room temperature, preventing caking and improving particle hardness.

6. Automated Screening and Packaging

The cooled particles are screened by the automated screening equipment to separate qualified particles from unqualified ones. The unqualified particles are returned to the granulator for reprocessing, reducing raw material waste. The qualified particles are transported to the automated packaging system, which completes quantitative packaging, labeling, and coding automatically. The packaging specifications can be adjusted according to needs, and the system can also realize automatic stacking, further improving production efficiency.
