The organic fertilizer project has a short construction period, high investment return, low risk, and short payback period. Generally, the investment is recovered within one year and profits are generated that year.
Generally, the production process design of pig manure organic fertilizer includes: 1. High-efficiency compound bacteria and their multiplication technology; 2. Advanced raw material blending technology and biological fermentation system; 3. The best special fertilizer Formula technology (can flexibly design the best combination of product formulas based on local soil and crop characteristics); 4. Reasonable secondary pollution (exhaust gas and waste gas) control technology; 5. Design and manufacturing technology of complete sets of fertilizer making process equipment.
Process flow: raw material selection (pig manure, etc.)—gt; drying and sterilization—gt; ingredient mixing—gt; granulation—gt; cooling and screening—gt; metering and sealing—gt; finished product storage .
The complete set of equipment is mainly composed of fermentation system, drying system, deodorization and dust removal system, crushing system, batching system, mixing system, granulation system and finished product packaging system; (harmless treatment of livestock and poultry manure, etc.) The fermentation system includes: feed conveyor, biological deodorizer, mixer, proprietary turning machine, oxygen supply system and automatic control system.
The construction scale is generally 30,000-250,000 tons per year. Local resources, market capacity, and market coverage radius must be comprehensively considered. Generally, small new plants have an annual output of 10,000 tons (1.5 tons/hour), 20,000 tons (3 tons/hour), and 30,000 tons (4.5 tons/hour). Medium-sized plants have an annual output of 50,000 to 100,000 tons. , large-scale factories have an annual output of 100,000-300,000 tons. The investment scale and product plan design need to be formulated based on the following conditions: raw material resource characteristics, local soil conditions, local planting structure and main crop varieties, factory site conditions, degree of automation of production, etc.
Recommend a top domestic expert network, which is also the first to research and develop bio-organic fertilizers in China. I have come into contact with their Ph.D.-level professionals, who are very professional in the process design, equipment, fermentation strains, fertilizer formulas, secondary pollution control and other complete bio-organic fertilizer factory construction of bio-organic fertilizers.

The pig manure organic fertilizer fertilizer production process consists of three parts:
[Mixing and kneading process]
1) For various materials, the reinforcing agent plays the role of efficient dispersion.
2) The reaction between the reinforcing agent and the material is strong.
3) Modify organic materials, reduce plasticity, increase density, facilitate granulation, and reduce mechanical wear.
[Granulating and rounding process]
This is the core of this process. It is a patented technology. The kneaded materials are rolled into balls at one time, with no material return and high efficiency. High, good strength.
1) Beautiful appearance, reasonable structure, safe and reliable, and easy to operate.
2) The machined granules have a strong anti-super capability, and the machine will not be stuck even when fully loaded, and there is no need to set up a separate feeding device.
3) It has small power and high output, and can be widely used for granulation in organic fertilizer, feed, agriculture, animal husbandry, sewage treatment and other industries.
[Intensifier technology]
1) The fertilizer grains can be strengthened and densified early, reducing drying costs, and are suitable for machine sowing.
2) The main ingredients of the enhancer come from 16 elements required for plant growth. The country says that the enhancer can increase fertilizer efficiency without side effects.
3) It is adaptable to different raw material enhancer formulas, so it can be widely used in the manufacture of organic and organic-inorganic compound fertilizers such as livestock manure, straw, peat, and weathered coal.
4) It has a coating effect on fertilizer granules, avoids the adhesion of urea in the formula to machinery, and reduces nitrogen loss.
5) The reaction between the enhancer and the material should be at room temperature. The reaction speed increases as the temperature increases.
To sum up, the new organic fertilizer manufacturing process of this project is the overall process of the above three new distribution sets. If one part is missing, the satisfactory effect will not be achieved. Therefore, the establishment of new enterprises and the transformation of old enterprises must be based on the overall design of the new process and the overall installation and commissioning.
