The drying process is the crucial final step in determining the quality of organic fertilizer. Common quality problems such as excessive moisture, nutrient loss, and particle damage are often related to inadequate drying. As a core piece of equipment in the subsequent processing, the drum fertilizer dryer, through its core functions of scientific temperature control and uniform drying, can precisely address these quality issues.

Addressing the problem of "excessive moisture leading to mold": The dryer uses layered temperature control technology to precisely reduce the material moisture content to a safe standard of 12%-14%. It employs a hot air circulation drying mode, allowing the hot, humid airflow to fully contact the material, quickly removing excess moisture and preventing mold and clumping caused by incomplete drying in certain areas. This extends the shelf life of the organic fertilizer and ensures stability during storage and transportation.

Solving the problem of "high temperatures causing nutrient loss": High-quality dryers have the capability of low-temperature, high-airflow drying, controlling the drying temperature within a reasonable range of 60-80℃. This temperature efficiently removes water while preventing the decomposition and loss of core nutrients such as organic matter, nitrogen, phosphorus, and potassium in the organic fertilizer due to high temperatures, ensuring that the finished product's fertilizer efficiency is not compromised.

Addressing the problem of "uneven drying leading to particle damage": The internal baffle structure of the dryer ensures uniform turning of the material, allowing every particle to come into contact with the hot air, preventing particle deformation and damage caused by local overheating or incomplete drying. At the same time, the dried material is rapidly cooled by a matching drum fertilizer cooler, further improving particle strength and reducing powdering loss during subsequent screening and packaging.

It should be noted that the effectiveness of the dryer depends on proper operation. As a key piece of equipment in the organic fertilizer production line, the precise drying function of the dryer not only improves the finished product's qualification rate but also enhances the market competitiveness of the organic fertilizer.
