Application of energy-saving refrigeration dehumidifiers in the production of NPK high-tower high-nitrogen high-concentration compound fertilizers: The principle behind using energy-saving refrigeration dehumidification units in compound fertilizer production is to utilize cold air that has been dehumidified and dried; this cold air is forced to flow in counterflow direction, with a blower being used to draw cold air from the inlet end of the equipment and bring it into contact with the material from the opposite direction, thereby forcing rapid cooling of the material. This allows the material to be cooled to near-room temperature quickly, enabling timely packaging and preventing caking during storage and transportation. The cooling effect is excellent – the outlet temperature of the dehumidification unit can be adjusted between 20–25°C, while the relative humidity can be adjusted between 40–60%. These units offer high production capacity, are easy to install and operate, and constitute an ideal cooling and dehumidification solution for the production of urea-based, sulfur-based, and nitro-based high-tower high-nitrogen high-concentration compound fertilizers. They are particularly suitable for use in high-temperature and high-humidity conditions during the production of high-nitrogen compound fertilizers.
