Introduction to the Principle of Organic Fertilizer Production Line and the Advantages of Chinese Equipment

Introduction to the Principle of Organic Fertilizer Production Line

The core principle of the organic fertilizer production line is aerobic fermentation, and the main process is as follows:

• Raw Material Pretreatment

  Collect various organic wastes, such as livestock and poultry manure, crop straws, urban sludge, etc. as raw materials. First, perform sorting to remove impurities, and then conduct crushing treatment to adjust the particle size of the raw materials. Generally, the appropriate particle size range is 12 - 60mm to increase the surface area of the raw materials, facilitate the reproduction of microorganisms and the entry of oxygen during the fermentation process, and improve the fermentation speed. At the same time, it is also necessary to adjust the moisture content and carbon - nitrogen ratio according to the composition of the raw materials. The appropriate organic matter content is 20% - 80%, and the optimal carbon - nitrogen ratio is 25:1. The moisture content is usually controlled at about 55% - 65%.

  
  

• Fermentation Stage

• Heat Production Stage (Mesophilic Stage, Temperature Rising Stage)

  In the early stage of fermentation, the mesophilic microorganisms in the compost pile use the soluble and easily degradable organic matter in the raw materials as nutrients and energy sources, multiply rapidly, and release heat energy, causing the compost pile temperature to rise continuously. In this stage, the temperature ranges from room temperature to 50°C, and the microorganisms are mainly mesophilic and aerobic, usually some non - spore - forming bacteria, including bacteria, fungi, and actinomycetes. Among them, bacteria mainly utilize water - soluble monosaccharides, etc., while actinomycetes and fungi have special functions in decomposing cellulose and hemicellulose substances.

• High - Temperature Stage

  When the compost pile temperature rises above 50°C, it enters the high - temperature stage. The mesophilic microorganisms are inhibited, and the thermophilic microorganisms gradually replace them. In addition to the continuous decomposition and transformation of the residual and newly formed soluble organic matter in the previous stage, complex organic substances such as hemicellulose, cellulose, and protein also begin to decompose strongly. At around 50°C, mainly thermophilic fungi and actinomycetes are active; when the temperature rises to 60°C, fungi almost completely stop activities, and only thermophilic actinomycetes and bacteria are active; when the temperature rises above 70°C, most thermophilic microorganisms are no longer suitable, and a large number of microorganisms die or enter a dormant state. At this time, the heat generated decreases, and the compost pile temperature automatically drops. When the compost pile temperature drops below 70°C, the dormant thermophilic microorganisms become active again, continue to decompose the difficult - to - decompose organic matter, the heat increases again, and the compost pile temperature is in a naturally regulated and prolonged high - temperature period. Through high temperature, the pathogens in the organic waste can be effectively killed to achieve the purpose of harmless treatment.

• Maturity Stage

  At the end of the high - temperature stage, only some difficult - to - decompose organic matter and newly formed humus remain. At this time, the microbial activity decreases, the heat generation decreases, and the temperature drops. The mesophilic microorganisms become dominant again and further decompose the remaining difficult - to - decompose organic matter. The humus continuously increases and tends to be stable. At this time, the fermentation enters the maturity stage. After the temperature drops, the oxygen demand is greatly reduced, the voids in the compost pile increase, and the oxygen diffusion ability is enhanced. At this time, only natural ventilation is required.

• Post - treatment Stage

  The materials after fermentation need to be post - treated, including removing impurities, further crushing, etc., to obtain an organic fertilizer product with uniform and fine texture. Then, according to needs, the powdered organic fertilizer can be processed into spherical granules or columnar granules through granulation equipment, and then go through processes such as drying and dehydration by a dryer, cooling by a cooler, screening by a sieving machine, coating by a coating machine, and finally packaged by an automatic quantitative packaging machine to produce the finished organic fertilizer for shipment.

Advantages of Chinese Organic Fertilizer Equipment

• High Cost - Performance Ratio

  Chinese organic fertilizer equipment has a high cost - performance ratio under the premise of ensuring quality and performance. Compared with similar foreign equipment, the price is more affordable, which can reduce the investment cost for enterprises, especially suitable for small and medium - sized organic fertilizer production enterprises. This enables more enterprises to enter the field of organic fertilizer production and promotes the development of the organic fertilizer industry.

• Strong Technological Innovation and Adaptability

  Domestic scientific research institutions and enterprises have continuously increased investment in research and development of organic fertilizer equipment and have achieved remarkable results in technological innovation. For example, a variety of equipment suitable for different raw materials, production scales, and process requirements has been developed, which can better meet the diverse needs of domestic organic fertilizer production. At the same time, Chinese organic fertilizer equipment can also be flexibly adjusted and optimized according to different environmental conditions and raw material characteristics in different regions of China, with strong adaptability.

• Energy Conservation and Environmental Protection

  With the improvement of environmental awareness and the requirements of relevant policies, Chinese organic fertilizer equipment pays more and more attention to energy conservation and environmental protection in the design and manufacturing process. For example, advanced energy - saving motors are adopted, and the process flow and equipment structure are optimized to reduce the energy consumption of the equipment; at the same time, through the installation of effective waste gas treatment, dust collection and other environmental protection facilities, pollutant emissions during the production process are reduced, achieving a win - win situation of economic and environmental benefits.

• Perfect After - sales Service

  Chinese organic fertilizer equipment manufacturers have established a relatively perfect after - sales service network in China, which can provide users with comprehensive after - sales services such as technical support, equipment maintenance, and spare parts supply in a timely manner. This helps users reduce equipment maintenance costs and downtime, improve production efficiency, and ensure the normal production and operation of enterprises.

• Customized Service

  Many Chinese equipment manufacturers provide customized services and can design and manufacture organic fertilizer production lines that meet the personalized needs of customers according to specific requirements such as production scale, raw material characteristics, and site conditions. This customized service model can better meet the special needs of different customers and improve the applicability and production efficiency of the equipment.
