What equipment is used in biofertilizer production?

Bio-organic fertilizer uses livestock and poultry manure, straw, food scraps, and other organic waste as raw materials. Through harmless treatment and functional bacteria enhancement, it is a green agricultural input that improves soil and enhances the quality of agricultural products. A complete bio-organic fertilizer production line is configured with equipment in four main stages: raw material pretreatment, fermentation and maturation, deep processing and shaping, and finished product packaging. This ensures that the fertilizer meets standards and achieves efficient and stable production.

Raw material pretreatment is the foundation of production. Core equipment includes a solid-liquid separator, a half-wet material crusher, and a horizontal mixer. The solid-liquid separator quickly reduces the moisture content of high-moisture raw materials such as manure, preventing anaerobic fermentation and foul odors. The semi-wet material crusher breaks down lumpy materials and coarse fibers, increasing the fermentation contact area. The horizontal mixer evenly mixes the main materials, auxiliary materials, and fermentation agents, adjusting the carbon-nitrogen ratio and moisture content to create conditions for rapid fermentation. A belt conveyor and silo are provided to ensure continuous raw material feeding and improve pretreatment efficiency.

Fermentation and maturation are the key processes in bio-organic fertilizer production, determining the fertilizer's harmlessness and effectiveness. Commonly used equipment includes trough-type compost turners or high-temperature aerobic fermentation tanks. Trough-type compost turners are suitable for large-scale open-air fermentation tanks, regularly turning the compost to supply oxygen and controlling the temperature at 55-65℃. Pathogens and insect eggs are killed within 7-15 days, completing the composting process. High-temperature aerobic fermentation tanks are closed designs, occupy little space, are highly automated, and have no odor leakage, making them suitable for areas with strict environmental regulations and small- to medium-scale production. Precise temperature and humidity control is required during fermentation to ensure complete decomposition of organic matter and avoid root burn or seedling damage.

The fermented material requires further processing, resulting in two production routes: powder and granules. Powder production requires a secondary pulverizer and a drum screen to refine the composted material to 80-100 mesh, removing impurities and obtaining a fine and uniform powder. Granulation production requires the addition of granulators, dryers, and coolers. Disc granulators are suitable for small to medium-scale production, extrusion granulators are suitable for high-fiber materials, and drum granulators meet the needs of large-scale production. Dryers use low-temperature drying to protect the activity of beneficial microorganisms, while coolers rapidly cool the granules to prevent clumping and extend shelf life.

The final step is an automatic packaging scale, which can quantitatively bag, seal, and print batch numbers according to specifications, enabling rapid warehousing of finished products. The entire production line is equipped with dust removal and deodorization systems, meeting environmental protection requirements.

Properly selected equipment can not only process organic waste and turn it into valuable resources, but also produce bio-organic fertilizers that meet national standards and have stable fertilizer effects, contributing to the green and sustainable development of agriculture.

Cake and meal materials are a type of nutrient rich organic fertilizer granulation raw material

图片
  Cake and meal materials are a type of nutrient rich organic fertilizer granulation raw material that plays an important role in improving the quality of organic fertilizers. Bean cake is one of the most common raw materials for cake and meal. The soybean cake left after pressing and extracting oil contains a large amount of protein, amino acids, as well as nutrients such as nitrogen, phosphorus, and potassium. These rich nutrients make soybean cake a high-quality raw material for organic fertilizers. After fermentation treatment, the high molecular weight organic matter in soybean cake is decomposed into small molecules, which are more easily absorbed and utilized by crops. Using an  organic fertilizer granulator  to turn fermented soybean cake into granular fertilizer can accurately control the nutrient content and release rate of the fertilizer, providing comprehensive and lasting nutritional support for crop growth. Rapeseed cake also has high nutritional value. It c...

The difference between rotary drum granulator and counter roll extrusion granulator

图片
  Both   rotary drum granulators   and roller extrusion granulators have their own advantages in fertilizer production, and they have significant differences in multiple dimensions. In terms of working principle, the  rotary drum granulator  uses a rotating drum to lift up the material internally. Under the action of centrifugal force, friction force, and gravity, the material circulates and the binder is sprayed to form the particles. The counter roll extrusion granulator uses a pair of rotating rollers to squeeze the material into the concave mold on the surface of the rollers, without the need for adhesive (which can be added in some cases). In terms of particle characteristics, the shape of the particles produced by the rotary drum granulator is relatively regular, mostly approximately spherical or elliptical, and the surface of the particles is relatively smooth. Due to the sufficient rolling of the material inside the drum, the internal structure of the pa...
