Bio-organic fertilizer equipment technology

Bio-organic fertilizer is a new type of fertilizer. It contains a lot of nutrients, which can reduce the incidence of plant diseases, enhance the immunity of crops, improve soil agglomeration and so on. Why does it have so many advantages? It is closely related to its production method. There are several common methods of making bio-organic fertilizers. No matter which method, it is inseparable from the processing capacity of bio-organic fertilizer equipment.

Two methods and production technology of using bio-organic fertilizer equipment to make bio-organic fertilizer
There are two common production methods for bio-organic fertilizers, namely, the mixed fermentation of manure and straw and the fermentation of livestock and poultry manure. The production of biological organic fertilizer equipment includes fermentation equipment, crushing equipment, mixing equipment, particle equipment and so on.
1. Use wastes such as livestock and poultry manure and crop straw to ferment organic fertilizers. When fermenting raw materials such as crop straw, about 20% of livestock and poultry manure can be added. When using livestock and poultry manure as the main raw material, about 20% of straw powder can be added. The fermentation method is the same as above.

If fermented with more acidic raw materials, about 1-3% lime powder should be added during fermentation to adjust the pH to neutral. The organic fertilizer fermented by this method is suitable for various crops and various soils.

2. Use livestock manure to ferment organic fertilizer. Use chicken manure, pig manure, sheep manure and other livestock and poultry manure as raw materials. The moisture is controlled at about 40%, and it contains about 1.6 tons of raw materials + 5 kg of probiotic bacteria liquid + 2-3 kg of corn flour mixed and crushed.

With stomping or trough composting, the composting temperature can be raised to about 50°C. Within 48 hours, the heap temperature can rise to above 60°C, or even as high as 70°C. Such a temperature in spring, summer and autumn usually takes 5-7 days to make all the raw materials in the heap decomposed, the stench disappears, and the pathogenic bacteria in the raw materials can be decomposed. , insect eggs, grass seeds, etc. are all killed. Fertilizers fermented in this way can be called ecological organic fertilizers or pollution-free organic fertilizers, which can be directly used in crops.

The production process of 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 introduced as examples, and other livestock and poultry dung can also be used)

2. Bar stack. According to the above ratio of raw materials, the strips are piled according to the needs. The length of the strips is not limited, the width is 2 meters, and the height is 1 meter. When stacking, the materials need to be stacked evenly layer by layer.

3. Add bacterial agent. Expand the volume of the fungus residue for the fungus agent at a ratio of 1:5, mix it evenly, and sprinkle it on the surface of the bar stack according to the number of bar stacks.

4. Stir and ferment. Stir the piles with a mixer evenly. After the temperature rises to above 60 degrees, turn the piles every 4-5 days. After fermenting for 15 days above 60 degrees, the piles can be put away.

5. Screening and processing. After fermentation according to the above steps, it becomes pure organic fertilizer after sieving and deep processing.

6. Granulation. The fermented pure organic fertilizer is granulated. According to different raw materials, choose granulator, disc granulator, extrusion granulator, extrusion granulator, etc.

7. Drying, cooling and packaging. The moisture content of the newly made granules is relatively large, and the moisture needs to be dried to less than 20% of the organic fertilizer standard.

Bio-organic fertilizer production process and bio-organic fertilizer equipment

1. Secondary fermentation. After the organic fertilizer is produced according to the above steps, the organic fertilizer is subjected to secondary stacking and fermentation, and the temperature is lowered to about 40 degrees after stacking for 15-20 days. The proportion of 500 is evenly added to the fermented organic fertilizer.

2. Add functional bacteria and stir well. The functional bacterial agent and the fermented organic fertilizer are evenly added to the organic fertilizer in proportion to reach the standard of bio-organic fertilizer after 7 days of composting and fermentation.

3. Screening and processing. The fermented bio-organic fertilizer is screened and put into storage.

4. Granulation. The processed functional pure bio-organic fertilizer is granulated. According to different raw materials, choose granulator, disc granulator, extrusion granulator, extrusion granulator, etc.

5. Drying, cooling and packaging. The moisture content of the newly made granules is relatively large, and the moisture needs to be dried to less than 20% of the organic fertilizer standard. When selecting a dryer for bio-organic fertilizer, a low temperature (temperature below 80 degrees) should be selected. After being cooled down by the cooler, it is directly packaged.
