During the production process, bio-organic fertilizer production lines often face various problems that affect product quality and production efficiency, requiring precise identification and proper resolution.

Two major issues are common in the raw material processing phase. First, an imbalance in the raw material ratio. If the ratio of livestock and poultry manure to straw is inappropriate, the carbon-nitrogen ratio will deviate from the optimal range (25:1-30:1), thereby affecting fermentation efficiency. For example, excessive straw will slow fermentation, while excessive manure will easily produce a foul odor. The solution is to strictly adjust the ratio according to test data and regularly test the raw material composition. Second, excessive raw material impurities. Impurities such as soil and gravel can damage subsequent equipment and reduce the purity of the organic fertilizer. A vibrating screen should be installed at the raw material inlet to preemptively remove impurities.

The fermentation stage of a bio-organic fertilizer production line is crucial. Common problems include abnormal fermentation temperatures and incomplete composting. Excessively high temperatures (over 70°C) kill beneficial microorganisms, while temperatures that are too low cannot effectively kill harmful bacteria and insect eggs. Temperature control requires adjusting ventilation and the frequency of the compost turning machine. For example, increase ventilation when the temperature is too high, reduce ventilation when it is too low, and cover with insulation film. Incompletely composted organic fertilizer, when applied to the soil, will ferment again, potentially burning crop roots. This can be addressed by extending the fermentation time until the material turns dark brown and has no noticeable odor before proceeding to the next step.

Common equipment operation issues include conveyor blockage and reduced grinder efficiency. Conveyor blockage is often caused by excessive moisture content or excessive feed rate. The moisture content of the raw materials should be controlled between 50% and 60%, and the feed rate should be adjusted according to the equipment’s capacity. Reduced grinder efficiency is often caused by blade wear or screen blockage. Blade wear should be regularly inspected and replaced, and the screen should be cleaned of impurities.

Product quality issues primarily arise from excessive moisture content and uneven nutrient distribution. Excessive moisture content can lead to clumping and mold in the finished product. Drying parameters should be optimized to ensure the moisture content is below 15%. Uneven nutrient distribution is related to insufficient mixing of raw materials. High-efficiency mixing equipment should be used in the mixing process to extend the mixing time and ensure uniform mixing of materials.

The core value of bio-organic fertilizer lies in the activity of its functional microorganisms, and every step in the bio-organic fertilizer production line can affect microbial survival. Effective protection requires scientific management and control throughout the entire process, from raw material processing to finished product packaging.

During the raw material pretreatment stage, the carbon-nitrogen ratio and moisture content must be precisely controlled. Microbial growth depends on an appropriate nutrient ratio. The raw material carbon-nitrogen ratio should be adjusted to between 25:1 and 30:1. Excessively high or low carbon-nitrogen ratios will inhibit microbial metabolism. Moisture content should also be controlled between 50% and 60%, with real-time monitoring using an intelligent moisture meter to prevent excessive moisture from leading to anaerobic fermentation, or excessive moisture from affecting microbial activity.

The fermentation stage is crucial for microbial propagation. When using a compost turning machine for fermentation, the turning frequency must be controlled to ensure that the oxygen content in the fermentation pile remains between 8% and 15% to prevent localized hypoxia that can lead to the death of beneficial bacteria. The fermentation temperature should be strictly controlled between 55°C and 65°C. This range effectively kills pathogens while ensuring the survival of functional bacteria. Precise adjustment can be achieved through temperature sensors linked to the temperature control system. The drying process must avoid high-temperature damage. Traditional high-temperature drying can easily lead to significant microbial inactivation. Low-temperature, negative-pressure drying technology is recommended. Keep the drying temperature between 35°C and 45°C, while maintaining appropriate wind speeds. Reduce moisture to below 15% within 4-6 hours to maximize microbial activity. After drying, the product must be quickly cooled to room temperature to prevent residual heat from affecting the stability of the inoculum.

Product handling and storage are equally important. Before packaging, the product must be screened in a sterile workshop to remove impurities and prevent contamination from external bacteria. Light-proof, breathable inner film packaging bags should be used to prevent direct ultraviolet radiation from damaging microbial cells, and a one-way exhaust valve should be installed to balance the air pressure within the bag. Storage warehouses should be ventilated and dry, with a temperature of 20°C to 25°C and a relative humidity below 60%. Regular microbial counts should be tested to ensure that the product meets the required activity standards before shipment.

Protecting microbial activity throughout the entire bio-organic fertilizer production line requires a combination of process optimization and intelligent management and control. By precisely controlling environmental parameters, bio-organic fertilizers can truly realize their ecological and agricultural value.

The bio-organic fertilizer production line is the core vehicle for transforming agricultural waste into high-quality fertilizer. Its production process requires scientific proportioning and precise processing to ensure the fertilizer is both nutritious and active.

The first step in production is raw material pretreatment. Workers transport raw materials such as livestock and poultry manure, straw, and mushroom residue to the workshop, where they are sorted to remove impurities. A crusher then pulverizes the straw and other coarse fiber materials to 2-5 mm. An automatic batching system then automatically mixes the various raw materials according to the optimal carbon-nitrogen ratio of 30:1 and adds composting agents, laying the foundation for subsequent fermentation.

The second step is the high-temperature aerobic fermentation stage. The mixed raw materials are fed into a fermentation tank or vat, where the fermentation system continuously controls temperature, humidity, and oxygen content. The temperature initially rises to above 55°C to kill insect eggs and pathogens; in the middle, it is maintained at 60-70°C to promote microbial decomposition of organic matter; and in the later stages, the temperature gradually decreases to form stable humus. The entire process takes approximately 7-15 days, during which time a compost turning machine turns the fertilizer every 2-3 days to ensure even fermentation.

After fermentation is complete, the material enters the advanced processing stage. A drum screener separates the uncomposted coarse material (which returns to the fermentation stage). Qualified material is then fed into a granulator (such as a rotary drum granulator or a new type organic fertilizer granulator). Depending on market demand, it can be produced in various forms, such as granules or powders. The granular fertilizer needs to go through a drum fertilizer dryer to reduce the moisture content to below 15%, and then pass through a drum cooler to cool it to room temperature to prevent clumping.

Finally, the finished product is processed and tested. After cooling, the fertilizer is coated with a probiotic agent in a film coating machine to improve its effectiveness and stability. It is then weighed and packaged. Quality inspection departments will sample and test the fertilizer for indicators such as organic matter content and effective viable bacterial count. Only products that meet national standards are labeled and shipped to farmland, providing green energy for crop growth.

With the trend toward green agricultural development, investing in a bio-organic fertilizer production line is becoming a highly promising option, offering numerous significant benefits.

From a market perspective, demand for bio-organic fertilizer is growing rapidly. With consumers’ increasing interest in healthy food and organic produce, organic agriculture is booming, directly driving strong demand for bio-organic fertilizer. More and more farmers are choosing to use bio-organic fertilizer to reduce chemical residues, leading to continued market expansion. Furthermore, bio-organic fertilizer offers a competitive price compared to chemical fertilizers, which have higher production costs, making it more readily accepted by the market and providing investors with ample profit potential.

Environmental benefits are also a major drawback of investing in a bio-organic fertilizer production line. Currently, the disposal of organic waste, such as livestock and poultry waste and crop straw, is a major challenge. Improper disposal can cause serious environmental pollution. A bio-organic fertilizer production line can transform this waste into high-quality fertilizer through a series of processes. This not only solves the problem of waste pollution but also enables resource recycling, reduces negative environmental impacts, and contributes to ecological improvements. Regarding soil improvement, bio-organic fertilizers are rich in nutrients and beneficial microorganisms, effectively improving soil structure, increasing water and fertilizer retention, and boosting soil fertility. Long-term use of bio-organic fertilizers can make the soil more fertile and loose, promoting the growth and development of crops, increasing crop yields and quality, and promoting sustainable agricultural development.

In addition, investing in a bio-organic fertilizer production line offers policy support. To promote green agricultural development, the government strongly encourages the production and use of organic fertilizers and has introduced numerous preferential policies and subsidies, reducing investment risks and increasing returns for investors.

In summary, investing in a bio-organic fertilizer production line can bring significant economic benefits, as well as positive environmental and social benefits. It aligns with the direction of sustainable agricultural development and is a highly valuable investment option.
