Organic fertilizer production line with an annual output of 10,000 tons
In recent years, the livestock and poultry breeding industry has developed rapidly, and has gradually formed serialized and specialized production. At the same time, it has also brought a series of environmental problems. , the waste water discharge is large. If it is discharged without treatment, it will cause serious non-point source pollution around the city. Handling farm manure well is a requirement to ensure a reasonable environment for farms, as well as a legal requirement to avoid polluting the surrounding environment and causing public hazards. At the same time, rational use of manure can also turn waste into treasure and generate certain economic benefits.Livestock and poultry manure contains a large amount of organic matter and abundant nutrients such as nitrogen, phosphorus, and potassium, and is a valuable resource for sustainable agricultural development. Therefore, aerobic composting of manure is currently a widely used treatment method. According to the characteristics of the raw materials and auxiliary materials of the feces, according to the carbon-nitrogen ratio and water content required by the compost, the feces and the auxiliary materials are mixed in a certain proportion, and the oxygen and temperature in the compost are properly controlled, so that the feces can be quickly fermented to produce organic fertilizers. The advantage of this method for manure treatment is that the final product has less odor, is dry, is easy to package and apply, and can be used in agricultural production as a soil conditioner or organic fertilizer.
Bio-organic fertilizer production equipment, before introducing bio-organic fertilizer equipment, let's talk about the characteristics and production methods of bio-organic fertilizer. The so-called national standard of bio-organic fertilizer is that each gram of fertilizer must reach 20 million beneficial microorganisms, which poses a problem for producers, that is, it cannot be produced at high temperature, otherwise the beneficial microorganisms will be killed, and the product will not meet the standard. If you want the product to meet the standard, and you have to reach a certain temperature during drying, the traditional solution is to lengthen the drying equipment of the bio-organic fertilizer production line and use low temperature and large air volume for production, which not only increases the cost of the equipment, but also increases the production plant. It also has to be increased, a lot of investment has been increased, and production is still not good. In order to solve this problem, the company's engineers cooperated with many customers to analyze, based on years of practical experience, the engineers have boldly explored and innovated, and finally developed a simple and easy-to-operate multi-functional granulation process. The pellet speed is fast, the ball formation rate and the finished product rate are high.

Production process and process:
1. Harmless treatment of raw materials:
Primary aerobic fermentation - secondary anaerobic fermentation
Livestock and poultry manure is mixed with an appropriate amount of straw powder. The amount of mixing depends on the moisture content of cow and sheep manure. Generally, the moisture content of 45% is required for fermentation. that is scattered. Then add cornmeal or rice bran and bacteria. The function of cornmeal is to increase the sugar content for the fermentation of bacteria, so that the multi-dimensional complex enzyme bacteria will soon take an absolute advantage. Add the prepared mixture to the blender for stirring, and the stirring must be even and thorough, without leaving any lumps. The stirred ingredients are piled into strips with a width of 1.5m-2m, a height of 0.8m-1.2m and a length of not less than 3m. During the fermentation process, pay attention to proper oxygen supply and turning over (the temperature should be turned over when the temperature rises to 75°C or above several times,) the temperature rise is controlled at about 65 ℃, and the temperature is too high, which will affect the nutrients. The moisture content of the fermentation material should be controlled at 60-65%. Too high or too low is not conducive to fermentation, too little water, slow fermentation; too much water will lead to poor ventilation, slow heating, and produce odor. After composting, it will heat up in 2 days, become odorless in 3 days, loosen in 7 days, become fragrant in 9 days, and become fertilizer in 10 days. On the second day of composting, the temperature can reach 60℃-80℃, killing diseases and insect pests such as Escherichia coli and eggs; on the fourth day, the odor of cow and sheep dung is eliminated; on the seventh day, the compost becomes loose and dry, covered with white mycelium ; On the 9th day, a wine koji fragrance was emitted; on the 10th day, the bacterial fertilizer was fermented and matured.
The second itch-weary fermentation is the so-called post-aging stage, also known as the second fermentation. After 7 days, the material can be decomposed and enter the post-aging stage. Before entering the post-aging stage, when the moisture content of the material drops to 30%, the granulation workshop can be used to pre-process the raw materials before granulation.
2. Raw material pretreatment: raw material crushing - sorting and screening

4. Raw material granulation
5. Particle moisture drying and dehumidification
6. Cool down and solidify
7. Particle classification and screening
8. Finished granule coating film
9. Finished Packaging
