Production technology of organic-inorganic compound fertilizer by high tower melting process

The current production process of organic-inorganic fertilizer and the production process of organic-inorganic compound fertilizer by tower melting process are introduced. The effects of pH value, water content and temperature influence on Maillard reaction of slurry are studied, the technology indexes are determined to provide basic data and research direction for the process of industrial production. The results show: under the conditions of temperature≤113 ℃, pH 6-7, w(H2O) 0.5%-0.7%, the Maillard reaction in granulation slurry is placid, the quality of organic-inorganic compound fertilizer is stable, which can meet the needs of industrial production.
