Bio-organic fertilizer production process and equipment

Bio-organic fertilizer is a new type of fertilizer. It contains a lot of nutrients, which can reduce the incidence of plants, enhance the immunity of crops, and improve soil agglomeration. Why does it have so many advantages? It is closely related to its production method. There are several common methods for making bio-organic fertilizer. Either way, it is inseparable from the processing capacity of bio-organic fertilizer equipment.

Bio-organic fertilizer production method:

There are two common production methods for bio-organic fertilizer, which are mixed fermentation of manure straw and fermentation of livestock and poultry manure. The equipment for making bio-organic fertilizer includes fermentation equipment, crushing equipment, mixing equipment, granular equipment, and so on.
1. Use wastes such as livestock manure and crop straw to ferment organic fertilizer. When using crop straw and other raw materials for fermentation, about 20% of livestock manure can be added, and when using livestock and poultry manure as the main raw material, about 20% of straw powder can be added.
If fermented with more acidic raw materials, 1-3% lime powder should be added during fermentation to adjust the pH to neutral.
2. Fermentation of organic fertilizer using animal manure. Use chicken manure, pig manure, sheep manure, and other animal manure as raw materials. The water content is controlled at about 40%, and about 1.6 tons of raw materials, 5 kilograms of probiotic liquid, and 2-3 kilograms of cornflour are crushed.

Production process of bio-organic fertilizer:

1. The ratio of raw materials per ton. 500 kg of cow manure + 300 kg of duck manure + 200 kg of bacterial residue + 100 g of RW bacterial agent.　(The above cow dung and duck dung are taken as examples, and other livestock and poultry dung can also be used)
2. Strip piles. According to the above raw material ratio, the pile is carried out according to the needs. The length of the pile is not limited, the width is 2 meters, and the height is 1 meter.
3. Add a bacteria agent. Increase the volume of the fungus residue with a ratio of 1:5, mix it evenly, and sprinkle it on the surface of the pile according to the number of piles.
4. Stir and ferment. Use a compost pile turner to stir the pile evenly. After the temperature rises above 60 degrees, turn the pile every 4-5 days. After the temperature is above 60 degrees, the pile can be put away after 15 days of fermentation.
5. Secondary fermentation. According to the above steps to produce organic fertilizer, the organic fertilizer for secondary stacking fermentation, stacking 15-20 days of temperature to 40 degrees or so, will have phosphorus solubilization, potassium solubilization, nitrogen fixation, underground pest control function of bacteria according to the ratio of 1:500 evenly added to the organic fertilizer has been fermented.
6. Add functional bacteria and stir evenly. The functional bacteria and fermented organic fertilizer are evenly added to the organic fertilizer in proportion to the pile and fermented for 7 days to reach the standard of bio-organic fertilizer.
7. Sieving and processing. The fermented bio-organic fertilizer is screened and stored.
8. Granulation. The processed functional pure bio-organic fertilizer is granulated.
9. Drying, cooling, and packaging. The moisture content of the freshly manufactured granules is relatively large, and the moisture needs to be dried to less than 20% of the organic fertilizer standard. When choosing a dryer for bio-organic fertilizer, choose a low temperature (temperature lower than 80 degrees) to dry the granular organic fertilizer. After being cooled by the cooler, it is directly packaged.

Note: If the drying temperature is too high, you need to add a coating machine, and add biological bacteria to the coating machine. If the drying temperature is too high, most of the biological bacteria will be killed, so you need to add biological bacteria after drying.
