Organic fertilizer production is a systematic project that converts organic waste such as livestock manure, straw, and bacterial residue into high-quality fertilizers. Among them, "fermentation and maturation" and "granulation and shaping" are the two core links that determine product quality. Many investors have purchased complete sets of equipment, but due to a lack of understanding of the process flow and improper connection of links, the qualified rate of finished products is low and the production capacity does not meet the standards. This article will take the "annual production of 10000 tons of organic fertilizer production line" as a reference, starting from the entire process of "raw material pretreatment → fermentation and maturation → granulation and molding → drying and cooling → screening and packaging", explaining in detail the operating standards, key parameters, and common problem solutions of each link, to help enterprises achieve efficient and stable production.

The organic fertilizer production line, from fermentation to granulation, is not a simple superposition of isolated links, but a systematic engineering of "pretreatment fermentation granulation subsequent treatment" - inadequate pretreatment can lead to low fermentation efficiency, incomplete fermentation can affect granulation molding rate, and improper granulation parameters can reduce product quality. In actual production, enterprises need to establish a "full process parameter record table" to record the operating parameters, testing results, and problem handling plans of each link, and optimize the process through data accumulation (such as adjusting the fermentation flipping frequency according to the characteristics of raw materials and optimizing the granulation mold aperture according to the requirements of finished products). Only by strictly controlling the standards of each link can we achieve the goal of "efficient conversion of raw materials, stable quality of finished products, and environmentally compliant production", and make the organic fertilizer production line truly a profitable carrier for "turning waste into treasure".
