Furuixue Solves Indonesian NPK Fertilizer Caking Problem

For compound fertilizer manufacturers across Southeast Asia, high temperature and heavy rainfall bring constant challenges to finished‑product storage. Indonesia’s tropical climate features high humidity all year round. NPK compound fertilizer produced by roller granulation has porous particle structure and large specific surface area. Such fertilizer easily absorbs moisture from ambient air during transportation and long‑term warehouse stacking, resulting in particle agglomeration, hard caking and powder generation. Severe caking will affect bag‑opening, spreading and mechanical fertilization, bringing extra losses to fertilizer factories.

Many local producers try different anti‑caking materials, yet ordinary liquid anti‑caking oil may face troubles such as oil stickiness, particle surface over‑coating and dust‑residue problems under Indonesia’s humid working conditions. In some production lines, customers prefer dry powder‑based anti‑caking additives to match their existing coating process.

We have developed a professional powder‑type anti‑caking agent specially adapted to roller granulation NPK compound fertilizer. This powder anti‑caking agent can be used alone or combined with anti‑caking oil according to actual production requirements. It coats evenly on fertilizer particle surfaces after powder coating equipment. It suppresses crystal‑bridge formation caused by moisture absorption, keeps NPK granules loose during long‑term storage, and will not negatively interfere with fertilizer nutrient indexes. No large‑scale reconstruction of existing roller granulation and coating facilities is needed.

One of our long‑term cooperative customers in Indonesia is engaged in roller granulation compound fertilizer production. Faced with local high‑humidity storage conditions, the customer tested our powder anti‑caking agent in formal mass production. After continuous warehouse observation under real Indonesian tropical environment, the compound fertilizer maintained good loose state. The customer recognized the practical anti‑caking effect and placed repeated orders for stable supply.

Different fertilizer formulas bring different caking risks. Sulfur‑based, chlorine‑based and high‑nitrogen NPK show different hygroscopic characteristics. Our team can adjust powder anti‑caking agent formula according to customers’ raw material ratio, granulation process, local climate and storage cycle, providing matched fertilizer anti‑caking solutions.

At present, our fertilizer anti‑caking series including powder anti‑caking agent, anti‑caking oil and oil‑powder combined system have been supplied to multiple Southeast Asian markets. We keep optimizing additive products for tropical working scenarios, helping more fertilizer factories reduce caking‑related waste and improve finished‑fertilizer market competitiveness.
