To effectively reduce the waste of resources in organic fertilizer equipment, we can start from the links of "raw material management-process optimization-equipment upgrade-digital management" to form a closed-loop control system. The specific measures are as follows:

1. Raw material management: Use closed transport vehicles to collect perishable organic waste to reduce odor volatilization and leachate leakage during transportation. Set up independent unloading areas for dry auxiliary materials such as straw and rice husks, and configure spray dust suppression devices to reduce dust emissions in unloading and crushing. Pre-sorting removes non-fermentable impurities such as stones and metals to avoid ineffective energy consumption and equipment wear.

2. Process optimization: The organic fertilizer production line can use mechanically enhanced high-temperature aerobic fermentation technology to shorten the fermentation cycle by more than 30%, reduce energy consumption and site occupation. Set up local closed and negative pressure collection systems at dust-producing points such as crushing, mixing, and screening, and cooperate with bag or wet dust removal to reduce dust emission concentration.

3. Equipment upgrade: Use variable frequency speed control motors and high-efficiency reducers; at the same time, use energy feedback devices to recover braking energy. Introduce intelligent control systems to monitor key parameters such as temperature, humidity, current, vibration, etc. in real time, automatically adjust the frequency of turning the compost, ventilation volume and granulation moisture, and reduce energy and raw material waste caused by excessive processing.

4. Digital management: data-driven, continuous improvement, optimize formula and process parameters through big data algorithms, achieve precise ingredients, precise fermentation, precise granulation, and reduce excessive feeding and rework.

Through the above comprehensive measures, organic fertilizer equipment can significantly reduce resource waste and improve economic benefits and environmental friendliness.
