Do you know what is what is the main process in making biofertilizer? Fermentation, granulation, drying and cooling, and the addition of microbial agents are essential. You need to strictly control the process flow to obtain high-quality bio fertilizers.
How to make high-quailty bio compost for biofertilizer production?
Advanced fermentation technology is the first step in making high-quality biofertilizers. Strip composting is the most common composting process.
Mix different types of organic raw materials (such as feces, kitchen waste, crop straw, etc.) evenly and compost them into a triangle or trapezoid with a height of 1.5 meters to 2 meters, a width of 2-3 meters, and a length of more than 3 meters. The suitable organic microbial carbon-nitrogen ratio (C/N) is 20~35/1. At the same time, the moisture should keep in 60-65% during the fermentation process. You can use windrow type composting machine to control the temperature, humidity, and moisture in the compost.
Key step for converting powder compost biofertilizer into granules:
Granulation is the most critical process in making biofertilizer. Common granulation processes include wet granulation and dry granulation. You can choose according to the moisture content of the raw materials. Wet granulation requires the feed moisture to be around 30%, while dry granulation requires the material to be 10%, which is mostly used to produce bio compound fertilizers.
The needed granulation machine in YUSHUNXIN has the dry roller extrusion granulator. wet disc granulator, and drum pelletizer. Please note: Before granulation, it is most appropriate to crush the raw material into a particle size of about 50 mesh.
After granulation process, what should i do to make bio fertilizer?
In order to maintain the stability of the biological fertilizer, you need to dry and cool it. The hot air furnace sends hot air into the drum dryer in a downstream manner, the biofertilizers temperature continues to rise, the surface moisture gradually evaporates, and the moisture decreases. Producing compound biofertilizer should pay attentation to its heat-sensitive. When it has a high moisture content, the only way to speed up the drying speed is to open the hot air door and increase the amount of hot water.
