To reduce energy consumption in biology organic fertilizer dryers, a comprehensive management approach is required—encompassing raw material pretreatment, hot air utilization, equipment operation, and process optimization—to achieve energy savings and cost reductions while simultaneously ensuring effective drying results and fertilizer potency.

Effective raw material pretreatment is the key to energy conservation. Before entering the dryer, the moisture content of raw materials should be reduced through methods such as fermentation, composting, and mechanical dewatering to prevent high-moisture materials from increasing the drying load. Additionally, any agglomerated materials should be crushed and broken up to ensure uniform particle size, thereby increasing the contact surface area with the hot air, enhancing heat exchange efficiency, and minimizing heat loss.

Optimizing the hot air system is crucial for improving thermal energy utilization. Selecting high-efficiency hot air furnaces or burners ensures complete fuel combustion, thereby preventing energy losses caused by incomplete combustion. Furthermore, properly balancing hot air temperature and airflow—specifically by adopting a "low-temperature, high-airflow" process—serves to both preserve the viability of beneficial microbial strains and reduce energy consumption.

Standardizing the operation of fertilizer production machine is essential for boosting drying efficiency. The rotational speed of the drying drum should be adjusted according to the specific characteristics of the material to ensure uniform scattering and prevent material accumulation; this avoids increased energy consumption resulting from excessively long or short residence times. Regular inspection and maintenance of the lifting flights (lifters) are also necessary to prevent deformation or damage that could lead to uneven material distribution. Maintaining a continuous and stable feed rate helps prevent frequent fluctuations in furnace temperature, thereby reducing wasteful energy consumption.

Strengthening equipment insulation and daily operational management is also vital. Installing an insulation layer on the exterior of the drying drum minimizes heat dissipation from the drum's surface, while promptly cleaning any material adhering to the interior of the drum prevents increased equipment load. The implementation of automated temperature control and variable-frequency drive systems allows for the precise regulation of temperature and airflow, thereby minimizing errors associated with manual operation. Through the application of these measures, the overall energy consumption of the dryer can be effectively reduced, leading to enhanced economic benefits for the production line.
