Planning a small-scale organic fertilizer produciton line requires detailed planning from multiple perspectives. The following are specific steps and recommendations:

1. Site Selection and Site Planning: Choose a location close to raw material sources and sales markets to reduce transportation costs and enhance market competitiveness. The plant should be located on flat terrain with good drainage and a low groundwater level to avoid flooding during the rainy season. Ensure that the selected site complies with local environmental regulations and avoid building in environmentally sensitive areas. The site should include areas such as a drying yard, fermentation area, organic fertilizer production and processing area, packaging area, and product warehouse.

2. Equipment Configuration: Select affordable organic fertilizer euqipment with appropriate production capacity based on your development needs.

3. Personnel Requirements and Training Plan: Based on the production process and equipment requirements, determine the required positions for production management, operators, quality control, and sales personnel. Provide employees with necessary operational, safety, and quality management training to ensure efficient, safe, and consistent production quality.

4. Production Process Planning: For raw material pretreatment, livestock and poultry manure is mixed with straw and other materials for fermentation. The fermented material is crushed in a pulverizer, and nitrogen, phosphorus, and potassium are added according to the formula. A fertilizer granualtor is used for granulation, followed by cooling. The finished product is packaged and stored in a dry, well-ventilated warehouse.

5. Environmental and Safety Design: Environmental protection measures for exhaust gas, wastewater, and noise emissions are planned to ensure compliance with local environmental regulations. Safety features such as fire protection, explosion prevention, and emergency exits are considered to ensure the safety of personnel and equipment during production.

Through the above planning, an efficient and environmentally friendly small-scale organic fertilizer production line can be established, contributing to the development of sustainable agriculture.
