Description

Technical Field

[0001] This utility model relates to the field of liquid water-soluble fertilizer production technology, and in particular to an organic water-soluble fertilizer production device. Background Technology

[0002] The organic water-soluble fertilizer market is booming. In 2022, the Chinese water-soluble fertilizer market reached 69.75 billion yuan, with organic water-soluble fertilizer accounting for only about 2%, but demand is on the rise. It is projected that the market size will expand to 86.048 billion yuan by 2025. Production is concentrated in agriculturally developed regions or areas with good fertigation practices, such as Liaoning and Shandong. Production processes are constantly improving; companies are using advanced equipment and automated systems to ensure precise ingredient mixing and uniform blending, meticulous processing of organic raw materials, strict quality control, and the use of environmentally friendly processes and materials, along with standardized labeling. Numerous companies have entered the market, leading to fierce competition; however, high-quality products remain relatively scarce, and some companies are breaking through by leveraging technological innovation and collaboration.

[0003] Organic water-soluble fertilizers provide timely and efficient nutrient supply, which can increase crop yields and improve quality, resulting in plump fruits and nutritious vegetables, thereby increasing farmers' income. They also facilitate resource recycling, allowing industrial and agricultural organic waste to be converted into fertilizer, reducing pollution and broadening raw material channels. Furthermore, they better meet ecological and environmental protection needs, improving soil structure, preventing compaction and acidification, and reducing agricultural non-point source pollution.

[0004] Currently, there are very few domestic manufacturers of organic liquid water-soluble fertilizers, and their production efficiency is low, nutrient concentration is difficult to guarantee, and market share is low. This seriously hinders the development of integrated water and fertilizer management in agriculture and does not improve fertilizer utilization efficiency. Therefore, developing a high-quality, high-efficiency liquid water-soluble fertilizer production device is of great significance for promoting agricultural production. Summary of the Invention
