Small-scale organic fertilizer production lines can be either powdered organic fertilizer production processes or granular organic fertilizer production processes. Among them, the powdered organic fertilizer process is a component of the granular organic fertilizer production process. Typically, an annual production capacity of 20,000 tons (inclusive) or less qualifies as a small-scale organic fertilizer production line. Based on the plans of most clients, small-scale organic fertilizer production lines primarily include process lines with capacities of 5,000 tons, 10,000 tons, 15,000 tons, and 20,000 tons. Since the powdered organic fertilizer production line is a component of the granular organic fertilizer production line, we will now focus on the granular organic fertilizer production process to detail the small-scale organic fertilizer production line process. The powdered organic fertilizer production process will then become clear.

According to the production process, the granular organic fertilizer production line is divided into the following stages:  ① Crushing process;  ② Fermentation process;  ③ Mixing process;  ④ Granulation process;  ⑤ Drying process;  ⑥ Screening process;  ⑦ Coating process;  ⑧ Packaging process.  The production process of powdered organic fertilizer includes the above stages:  ① Crushing process;  ② Fermentation process;  ⑧ Packaging process.  So, what conditions are required to build a small-scale organic fertilizer production line?  ① The construction of a small-scale organic fertilizer production line must comply with environmental protection policies. Environmental protection is not only a public demand but also a policy requirement for maintaining the environment in agricultural and livestock development.  ② Raw material sourcing: The radius of raw material supply determines the factory location, land investment, transportation investment, and other factors.  ③ Raw material types: The type of raw materials determines the specific equipment used in each production stage, affecting equipment investment costs.  ④ Production scale: The output of a small-scale organic fertilizer production line ranges from 3,000 to 20,000 tons annually, which defines the production capacity requirements for equipment and thus impacts costs.  ⑤ Resource recycling: This primarily relies on the recovery and utilization of various agricultural waste materials, such as using them as fuel or electrical energy sources, with the resulting biogas residue serving as raw material for organic fertilizers.  ⑥ Other uses of the small-scale organic fertilizer production line process: It can also be used for feed production.  ⑦ Factory site: The size of the production area and land investment must be determined based on the planned production scale.
