The following are various methods for improving drying equipment in organic fertilizer production lines:

1. Optimize the Hot Air System: Use high-efficiency, energy-saving hot air furnaces, such as biomass hot air furnaces or natural gas hot air furnaces, to increase hot air temperature and thermal efficiency, reducing energy consumption. Install a hot air circulation system to reintroduce some of the exhausted hot air into the drying system, improving thermal energy utilization.

2. Improve the Drying Process: Use a multi-stage drying process, dividing the drying process into three stages: pre-drying, main drying, and final drying, to gradually reduce the moisture content of the material. Use a low-temperature, high-volume drying method to lower the drying temperature, extend the drying time, and minimize nutrient loss in the material at high temperatures.

3. Optimize Equipment Structure: Add agitation devices, such as stirring blades or flaps, to the drying chamber to continuously stir the material during drying, improving drying uniformity.

4. Apply an Intelligent Control System: Install temperature and humidity sensors to monitor the temperature and humidity in the drying chamber in real time, and automatically adjust the hot air furnace power and air volume through an intelligent control system. Equip a fault warning system to promptly issue an alarm and shut down the organic fertilizer equipment when an abnormality occurs, preventing equipment damage.

5. Strengthen environmental protection measures: Install high-efficiency dust and odor removal equipment, such as cyclone dust collector, water film dust collectors, or biological deodorizers, at the drying equipment's exhaust outlet to reduce dust and odor emissions.

These improvements can effectively improve the efficiency and quality of drying equipment in organic fertilizer production lines, reducing production costs and environmental pollution.
