The stable operation and product quality of an organic fertilizer production line depend on strict control of each production stage. The following are key precautions to pay attention to during production, crucial for improving production efficiency and ensuring product safety.
In the raw material processing stage, raw materials must be strictly screened. Impurities such as plastics, metals, and stones should be avoided. These impurities can damage equipment such as crushers and granulators, and also affect the purity of the organic fertilizer. Simultaneously, the moisture content of the raw materials must be controlled, typically adjusted to 50%-60%. Excessive moisture content can lead to fermentation sticking, while insufficient moisture content will affect microbial activity and reduce fermentation efficiency.
Regarding equipment operation, a comprehensive inspection of the organic fertilizer production line equipment should be conducted before startup. Check the sharpness of the crusher blades, the integrity of the granulator molds, the appropriate tension of the conveyor belt, and the normal operation of the electrical and hydraulic systems of each piece of equipment to prevent production interruptions due to equipment failure. During operation, the equipment's running status must be monitored in real time, paying attention to any abnormalities in motor temperature and noise. If any problems such as equipment jamming or unusual noises are detected, the machine should be stopped immediately for repair to prevent further damage. Regular maintenance is also essential, including adding lubricating oil and cleaning residual materials from inside the equipment, to extend its lifespan.
The fermentation process is the core of organic fertilizer production, requiring precise control of environmental conditions. The temperature in the fermentation workshop should be maintained between 55℃ and 65℃. This temperature range effectively kills pathogens and insect eggs in the raw materials while promoting the decomposition of organic matter by microorganisms. The fermentation pile needs to be turned daily, with the frequency adjusted according to the fermentation progress, generally 1-2 times, to ensure ventilation, oxygen supply, and prevent anaerobic fermentation that produces odors. Furthermore, the pH value of the fermentation pile should be monitored. By adding an appropriate amount of regulator, the pH value should be controlled within the neutral range of 7-8 to provide a suitable environment for microbial growth and reproduction.
Quality testing and safety precautions are also crucial. Each batch of products must undergo sampling and testing, with indicators including organic matter content, total nitrogen, phosphorus, and potassium content, pH value, and heavy metal content, to ensure compliance with national organic fertilizer standards. Substandard products are strictly prohibited from leaving the factory. During production, operators must take necessary safety precautions, including wearing safety helmets, dust masks, and protective gloves to avoid dust inhalation and mechanical injuries. Simultaneously, the workshop must be equipped with fire-fighting equipment and have emergency plans in place to prevent accidents such as fires and equipment leaks.
In short, organic fertilizer production lines require meticulous attention to detail and standardized procedures. Comprehensive control from raw materials to finished products, and from equipment to personnel, is essential to achieving efficient, safe, and high-quality production, providing strong support for green agricultural development.
