Organic Fertilizer Production Line
The organic fertilizer production line is an industrial process specifically designed to convert organic waste (such as livestock manure, agricultural waste, urban sludge, etc.) into organic fertilizers. This production line uses a series of biochemical and physical processes to stabilize the nutrients in organic waste and produce organic fertilizers that are beneficial for crop growth. It not only solves the problem of waste disposal, but also promotes the sustainable development of agriculture.
Equipment Composition
The equipment composition of the organic fertilizer production line mainly includes the following parts:
Raw material pretreatment equipment: including crusher and screening machine, used to crush and screen large organic waste, remove impurities, and facilitate subsequent processing.
Fermentation equipment, such as compost fermentation turntables and fermentation tanks, converts organic waste into stable organic matter through the action of microorganisms, while killing pathogens and weed seeds.
Composting machine: During the composting process, the compost pile is periodically flipped to provide sufficient oxygen, promote microbial activity, and accelerate the fermentation process.
Granulation equipment: The fermented organic matter is processed into granular fertilizers through granulators such as disc granulators and drum granulators, which are convenient for storage and use.
Drying equipment: such as a rotary drum dryer, used to remove excess moisture from fertilizer particles after granulation and improve storage stability.
Cooling equipment: Cool and dry fertilizer particles to prevent high temperatures from affecting fertilizer performance.
Screening equipment: used to screen out fertilizer particles of appropriate size to ensure product consistency.
Coating equipment (optional): Apply a thin film on the surface of fertilizer particles to improve moisture resistance and control nutrient release rate.
Packaging equipment: Automatic packaging machine, used to weigh and package finished fertilizers.
Control system: including PLC control system and automation instruments, used to monitor and adjust key parameters in the production process, ensuring the efficient operation of the production line.
Granulation process
1. Raw material preparation and pretreatment
Collection and classification: Firstly, collect various organic wastes such as livestock and poultry manure, crop straw, food processing residues, etc., and conduct preliminary classification.
Crushing and mixing: Use a crusher to crush large pieces of raw materials to a particle size suitable for fermentation, and then mix the raw materials in a certain proportion to optimize the carbon nitrogen ratio and promote fermentation.
2. Fermentation
Composting fermentation: The pre treated raw materials are sent to the composting fermentation area, and through a natural or artificially controlled high-temperature fermentation process, microorganisms are used to degrade organic matter while killing pathogens and weed seeds. During the fermentation process, it is necessary to regularly flip the pile to provide sufficient oxygen and control the temperature.
Fermentation control: By monitoring temperature, humidity, and oxygen levels, adjust fermentation conditions to ensure an efficient and stable fermentation process.
3. Post processing
Screening and crushing: After fermentation, organic matter may need to be screened and crushed again to remove undecomposed impurities and ensure the uniformity of the raw materials.
Granulation: Use a granulator to turn fermented organic matter into granules, improving the storage and ease of use of fertilizers.
Drying: Granular organic fertilizers need to be dried to remove excess moisture and prevent clumping during storage.
Cooling: The dried fertilizer needs to be cooled to room temperature to prevent high temperatures from affecting the quality of the fertilizer.
Screening: Re screen fertilizer particles to ensure consistency in product particle size.
Coating (optional): Apply a thin film on the surface of fertilizer particles to improve moisture resistance and control nutrient release rate.
4. Packaging
Automatic packaging: Use an automatic packaging machine to weigh and package finished organic fertilizers, forming packaging bags that are easy to transport and sell.
5. Quality inspection and storage
Quality testing: Conduct quality testing on finished organic fertilizers to ensure compliance with relevant standards and regulations.
Storage and transportation: Qualified organic fertilizers are stored in dry and ventilated warehouses, waiting for further sales or transportation.
Process characteristics
- Environmental protection and energy conservation: Organic fertilizer production lines can effectively treat organic waste, reduce environmental pollution, and optimize processes and equipment to reduce energy consumption.
- Resource recycling: By converting waste into resources, the recycling of agricultural and livestock waste has been achieved, promoting the sustainable use of resources.
- Stable product quality: Through precise fermentation control and granulation technology, the organic fertilizers produced are ensured to maintain consistency in nutritional composition, particle size, and moisture content, thereby improving the effectiveness of fertilizer use.
- Flexibility: The production line can adjust the production formula and process parameters according to the type and quality of raw materials, as well as the needs of the target market, to produce different types of organic fertilizers.
- High degree of automation: By adopting an automated control system, from raw material processing to finished product packaging, the entire process of automated production is achieved, improving production efficiency and reducing manual operation errors.
