The energy-saving design of organic fertilizer coating machines is mainly reflected in the following aspects:

1. Optimization of hot air system: Some organic fertilizer coating machines adopt waste heat recovery technology to recover and utilize the heat generated during the fermentation process for preheating the feed or heating other production stages, reducing energy waste. Through the hot air circulation system, hot air is recycled within the equipment to enhance the efficiency of thermal energy utilization and reduce energy consumption.

2. Automation and intelligent control: Modern organic fertilizer coating machines are equipped with PLC control systems, which can automatically adjust parameters such as rotational speed, spray volume, and temperature according to the production requirements of the organic fertilizer production line, achieving precise control and optimized management. Organic fertilizer equipment can automatically switch to energy-saving mode according to actual production needs, reducing energy consumption.

3. High-efficiency spraying system: Advanced spraying technology is adopted to ensure that the coating material is evenly covered on the surface of the fertilizer particles, reducing material waste. The coating liquid is atomized and sprayed onto the particle surface by using high-pressure nozzles to improve the spraying efficiency and reduce energy consumption.

4. Material selection and equipment design: The main unit is lined with polypropylene or acid-resistant stainless steel to enhance the equipment's corrosion resistance and service life. According to the process requirements, a special design was made in the internal structure to improve the operational efficiency of the equipment.

5. Drying and curing assistance: Some equipment is equipped with a hot air system to accelerate the drying or curing of the coating material, reduce drying time, and enhance production efficiency. It adopts a double-layer cylinder design, with the inner layer being coated and the outer layer being dried, which improves the drying efficiency.

Through the above energy-saving design, the organic fertilizer coating machine can not only improve production efficiency but also significantly reduce energy consumption, achieving a win-win situation of environmental protection and economic benefits.
