China is a large agricultural country, with an effective land planting area of more than 3.1 billion mu, and a large demand for fertilizer. With the rapid development of social economy, people’s awareness and requirements for organic and green food are gradually increasing, and the development of organic agriculture and ecological agriculture is also gradually increasing. The application of chemical fertilizer in agricultural production has led to soil hardening and degradation of agricultural product quality, resulting in low crop yield. Therefore, the State encourages the use of organic fertilizer and has issued relevant subsidies and preferential policies, which has promoted the development of the organic fertilizer industry, and also brought good development opportunities and good market prospects to the organic fertilizer industry.
The factories that set up an organic fertilizer equipment production line to process fertilizer in the countryside are generally privately built, so a small organic fertilizer equipment production line with an annual output of about 10000 tons is sufficient to meet the sales demand. The primary focus of the organic fertilizer processing is the purchase of raw materials, and the most simple and small production line of organic fertilizer is raw and auxiliary materials:
- Organic main raw materials: livestock manure, domestic sludge, domestic garbage and other solid wastes account for about 50-80% of the formula;
- Inorganic main raw materials: urea, ammonium phosphate, superphosphate, calcium carbonate, potassium chloride, potassium sulfate, etc. account for about 10 to 30% of the formula;
- Medium and trace element additives account for about 10% of the formula;
- The bio-organic compound fertilizer also needs to add biological bacteria powder: 5 ‰ – 10%;
- Other raw materials that may be used as required: peat, oil residue, fly ash, etc;
- Auxiliary energy: water, electricity and coal.
Purchase organic fertilizer processing raw materials, chicken manure, pig manure, sheep manure, cow manure. These raw materials are not expensive, and the purchase price can be cheaper.
The investment of small organic fertilizer production line is between 80000 yuan and 120000 yuan. The main equipment of the small-scale organic fertilizer equipment production line includes fermentation tipping machine, pulverizer, granulator, screening machine, automatic weighing and packaging machine, etc. This series of small organic fertilizer production line has not only high cost performance, but also high efficiency, good energy saving and simple operation for workers. Equipment for small organic fertilizer production line:
- Fermentation tipping machine: ferment the materials in the fermentation process to turn over (flip);
- Pulverizer: pulverization of raw materials such as high humidity materials in the production process;
- Granulator: granulate the mixed materials; Convenient for sorting and packaging;
- Organic fertilizer screening machine: screen and classify the finished fertilizer;
- Automatic weighing and packaging machine: quantitative bagging and packaging of finished products.
