With the stable development of the economy, the damage and impact of various negative factors on the environment are also becoming increasingly apparent. Air pollution, soil compaction, soil alkalization, and livestock manure pollution, among other negative factors associated with economic development, directly affect the development of agricultural production and the improvement of people’s quality of life. Starting from the strategic height of long-term economic development, the country has formulated policies for energy conservation and environmental protection economic development, encouraging and holding back the development and growth of related industries, so as to steadily put the national economy on a new and healthy path of energy conservation and environmental protection development.

1. High yield: An organic fertilizer production line has an annual production capacity of 30000 tons and an annual fecal treatment capacity of 80000 cubic meters,

2. Large market demand: An organic fertilizer production line can not only meet the local fertilizer demand, but also meet the demand of surrounding markets. Bioorganic fertilizers are widely used in various fields such as farmland, fruit trees, flowers, landscaping, high-end lawns, and soil improvement, with good results.

3. Rich resources: Biological excrement, like oil, coal, and ore, is a wealth and resource of society. China has a vast territory and abundant raw material resources for organic fertilizer production lines.

4. High quality fertilizer: Taking livestock manure as an example, the final urine produced by a pig in a year can be combined with bedding to produce 2000-2500kg of high-quality organic fertilizer, which contains 11% -12% organic matter, 0.45% nitrogen, 0.19% phosphorus pentoxide, and 0.6% potassium oxide, which is sufficient for the annual fertilizer consumption of one acre of land. These organic fertilizers are rich in various nutrients such as nitrogen, phosphorus, and potassium, with a content of over 6% and an organic matter content of over 35%, all exceeding national standards.

5. Policy support: The government provides subsidies for agriculture, which greatly supports this industry, so making choices is a very good choice.

The products produced by small organic fertilizer production lines are made from fresh chicken and pig manure as raw materials, without any chemical components. However, the digestion ability of chickens and pigs is poor, and only 25% of the nutritional components can be consumed. The other 75% of the nutritional components in the feed are excreted with the manure, resulting in dry products containing nitrogen, phosphorus, potassium, organic matter, amino acids, proteins, and other components. Organic fertilizer granulation machines are helping to establish a resource-saving society in China, seizing every detail and preventing investment pollution. The development space of organic fertilizer production lines is enormous, while improving economic benefits and protecting the environment. In terms of crop production, solving environmental pollution is the top priority, promoting circular economy and developing organic agriculture, laying a solid foundation.

High temperature treatment method of organic fertilizer production line: it is mainly applicable to composting, which uses the energy released by organic matter differentiation to raise the temperature, so as to kill the pests and diseases predicted by fertilizer. High temperature composting should master the following skills:
(1) The required moisture content of composting is 60% – 75% of the dry data, that is, water droplets can be squeezed out when holding the data by hand, indicating that the moisture content is moderate.
(2) In the early stage of composting in the organic fertilizer production line, good ventilation conditions should be maintained. If necessary, ventilation tower and ventilation ditch can be set. In the later stage, the anaerobic condition should be adhered to. The aeration tower can be removed and the ventilation ditch can be blocked. It can be compacted and sealed to retain nutrition and promote the accumulation of humus.

(3) The internal temperature of compost can be controlled between 50 ℃ and 60 ℃. When the temperature is higher than 65 ℃, the fertilizer production machine can turn over the heap or add water to cool down, so as to facilitate the retention of nitrogen.
(4) The C / N ratio of composting data is 25 ∶ 1, which is conducive to the differentiation of organic matter by microorganisms.
(5) Control the appropriate pH value. During composting, 1-1.5 kg lime and other alkaline substances were added into 50 kg straw to adjust the pH value of compost at 7.5. The hygienic standard of high temperature composting is that the mortality rate of Ascaris lumbricoides eggs reaches 95% – 100%. Flies can be controlled effectively. There are no live maggots, pupae or newly emerged adult flies around the compost.

As a new type of mechanical equipment, the organic fertilizer production line is currently very popular. Its development in recent years has been recognized and favored by everyone. The reason is that it conforms to the trend of the times, responds to national policies, and has received strong subsidies and promotion from the country. Therefore, it is well-known to the people of the whole country. The future development of organic fertilizer production lines is still relatively optimistic. This has greatly stimulated the rapid rise of organic fertilizer production line manufacturers and can also bring high economic benefits to our country. So what are the characteristics of organic fertilizer production lines that can make the market demand so high? Where is its value reflected?

1. The organic fertilizer production line is committed to tracking the hot areas of international fertilizer technology innovation and the development direction of the fertilizer industry. It has collaborated with the Chinese Academy of Agricultural Sciences and the Chinese Institute of Agricultural Mechanization to conduct research on the industrialization technology of organic fertilizers and analyze the social benefits. How to fully utilize the resources of organic waste is an important issue for China to establish a resource-saving society, promote circular economy, and develop organic agriculture;

2. Some small organic fertilizer equipment or supporting equipment can be purchased by farmers through joint ventures, so that they can save time, materials, and use waste straw to make organic fertilizer. This not only saves energy and environmental protection, but also increases farmers’ income;

3. China is a major agricultural production country with rich experience in agricultural production. Therefore, organic fertilizer production lines can bring rich experience and excellent equipment to foreign countries, promoting the exchange of technical experience in organic fertilizer equipment at home and abroad;

4. China is a major consumer of fertilizers, and the production of fertilizers requires a large amount of non renewable resources such as coal, electricity, and natural gas. The development of this project utilizes solid organic waste through microbial fermentation to produce organic fertilizers, achieving the goal of saving non renewable resources and protecting the environment. The social benefits are enormous, which is in line with China’s energy conservation and emission reduction industrial policies.

In addition, organic fertilizer production lines also have many benefits, such as driving the development of the industry chain as you can see. Organic fertilizer equipment has developed to the present day, with a variety of equipment, such as organic fertilizer production lines, fermentation and pile flippers, organic fertilizer granulators, semi wet material crushers, roller extrusion granulators, organic fertilizer granulators, and so on. A series of complete organic fertilizer production lines drive the development of the entire fertilizer equipment industry.

In the early 1990s, China introduced foreign tank fermentation technology from foreign countries. On the basis of integrating various treatment methods, combined with the characteristics of China’s agricultural and animal husbandry business model, it adopted a comprehensive treatment of solar aerobic fermentation technology.

From the perspective of practicality and cost control, the trough fermentation system is the preferred process for organic fertilizer production line. Here we make a comparison and find that the self-propelled compost turning machine is flexible but has a large area; the fermentation cycle of the fermentation tank is short, but the cost is not suitable for popular demand. At present, the more widely used are the groove type compost turning machine, and the high-grade ones include the double-spiral stacker and the chain plate stacker, etc. There are many types of products, which can be ordered according to their own needs.

The use of solar energy for aerobic fermentation is a very important part of the organic fertilizer production line. During this period, the treatment of organic solid waste must solve the problems of drying, fermentation, sterilization, deodorization, etc., and finally obtain higher economic benefits at a lower cost. Before fermentation, various raw materials to be fermented are mixed in a certain proportion to meet the fermentation conditions such as moisture and carbon-nitrogen ratio, and the purpose of shortening the fermentation cycle is finally achieved to achieve the optimal fermentation effect.

In order to make organic solid waste into efficient organic fertilizer, it must be fully fermented and matured. The application of organic solid waste without fermentation or incomplete fermentation to the land is extremely harmful to crops. It can decompose in the soil to generate heat and carbon dioxide gas and other harmful substances, which seriously affects crop germination and crop root growth. The organic solid waste can achieve the purpose of eliminating harmful substances, germs, and reducing odor after full fermentation. At the same time, it occupies less space, increases the humus uniformly, and is more convenient to use when fertilizing. Fully fermented and decomposed is a necessary process to increase the effective ingredient humic acid in organic fertilizers. Organic raw materials made from organic fertilizers directly added to inorganic fertilizers without being processed in this step are organic-inorganic compound fertilizers. Low phytic acid is not good for crops and soil.

The entire production process of biofertilizer project is divided into ten steps, each of which will directly affect the quality of bio-organic fertilizer production line, which cannot be reduced in production.

The following is the process of producing biological organic fertilizer:
1. The raw materials such as animal manure must be fermented and rotted. During the entire fermentation process, harmful bacteria inside can be killed, which is also the most important in the entire organic fertilizer manufacturing process.

2. Secondly, the semi-wet material crusher of organic fertilizer crushing equipment is used to preliminarily decompose the raw materials.

3. Ingredients are a key step in fertilizer production. Its main function is to add appropriate ingredients in proportion to make the organic fertilizer rich in organic matter and improve its quality.

4. Granulation is required after the materials are evenly mixed, which is also the most important part of the whole process.

5. The material gets high temperature during the drying process, and then it needs to be cooled. Because water cannot be used for cooling, a cooling device is needed here.

6. Screening is the need to screen out the unqualified fertilizer, and the unqualified materials will return to the production line for qualified processing and processing again. The screening equipment here has the advantage of being efficient and easy to operate.

7. the stirred material into the required particles, especially suitable for high viscosity materials.

8. The material of the stirring container must meet the requirements of the production process, such as pressure resistance, temperature resistance, medium corrosion resistance, and product cleanness. Due to different materials, the manufacturing process and structure of the stirring container are also different.

9. Conveying is to transport the finished fertilizer to a higher place, and it is prepared for convenient storage.

10. Packaging is the last link in fertilizer equipment. In order to protect the product during circulation, facilitate storage and transportation, and promote sales, the overall name of the container, material, and auxiliary materials used in accordance with certain technical methods; also refers to the above to achieve the above. Objective To apply certain technical methods and other operating activities in the process of using containers, materials and auxiliary materials.

The equipment required for the production of bio-organic fertilizers are fermentation stackers, shredders, mixers, fertilizer granulator machine, dryers, sieving machines, and packaging machines.

Bio-organic fertilizer equipment has always been the star product of our factory. There are many production processes for producing bio-organic fertilizer, and each production process has its own characteristics. The key to the production process of biofertilizer project is the choice of granulation method. According to the production process requirements, the current granulation methods commonly used in bio-organic fertilizer are mainly disc granulation and stirring granulation. Due to different requirements of raw materials for different granulation methods, there are differences in the production process of biological organic fertilizer. At present, our organic fertilizer equipment has the following production processes.

Using the disk granulation production process, the raw materials need to be dried to remove a certain amount of water (when drying, the raw materials are sterilized), and then crushed, and then a certain amount of acid and alkali is added to adjust the PH of the carrier and mixed with the inorganic fertilizer part, and sent into The disc granulator sprays a certain amount of bacteria during the granulation process, and the granulated product is dried and sieved at low temperature to obtain the finished product.

The tooth-granulation granulation process is to use the high-speed rotating mechanical stirring force and the aerodynamic force generated thereby to continuously realize the process of mixing, granulating, spheroidizing and densifying the fine powder in the machine, thereby achieving the purpose of granulation. The shape of the particles is spherical, the sphericity is ≥0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is ≥90%. The size of the particle diameter can be appropriately adjusted by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the rotation speed the higher, the smaller the particles, and vice versa.

From the process flow, the two processes have the same equipment before granulation and the area is about the same, so the difference in investment mainly depends on the fertilizer granulator machine. The same is the case of a 10,000 t / a scale production capacity. 4000 ～ 5000 yuan / set, while the stirring granulator is generally 50,000 yuan / set (the specific price is determined by the specific specifications and the manufacturer’s price is for reference only), and the low temperature dryer is 12-15 thousand yuan / set. Therefore, from the perspective of investment, the disc granulation production process is relatively higher than the extrusion granulation process, and the specific production process needs to be tailored by a professional technical team.

The future development potential of organic fertilizer production lines is enormous. Due to the current agricultural situation in China, organic fertilizer raw materials are abundant and of high quality, and the market demand for organic fertilizer is also large. The scale of use of organic fertilizer is also very wide, whether it is farmland or vegetable cultivation greenhouses, or the beautification of fruit trees, flower gardens, and soil improvement, organic fertilizer is widely used. It also conforms to the national agricultural development policy, indicating that the prospect of organic fertilizer production lines is very broad.

The organic fertilizer production line is composed of many small machinery and equipment, each of which affects, restricts, and complements each other. After a certain process flow, high-quality organic fertilizer can be processed. The production process of the organic fertilizer production line is as follows:

1. The raw materials, auxiliary materials, and fermentation agents are pre mixed evenly through the equipment in proportion, with a moisture content of about 60. They are transported by conveyor belts and distributed to the fermentation tank through shuttle belt distribution machines.

2. In order to fully ferment the materials in the fermentation tank, a chain plate tipping machine is used to flip and shift the materials. At the same time, the aeration system is used to aerate the bottom of the tank, allowing the materials to undergo aerobic fermentation.

3. The fermentation of the material is basically completed in the fermentation tank for about 7 to 10 days. Under the flipping displacement of the flipping machine, the material is flipped to the discharge end, and then transported to the aging tank through the pool changing discharge machine, discharge belt machine, and shuttle type distribution machine for secondary fermentation of aging, so that the material is thoroughly decomposed.

4. The decomposed materials are transported to the granulation workshop through conveyor belts, and are screened and processed by drum screening machines and vertical crushers to remove large pieces of material;

5. The screened materials and other inorganic nutrients are proportionally transported to a dual shaft paddle mixer using a batching belt scale for mixing. Uniformly mixed materials can be packaged as powder products, and can also be granulated by adjusting the moisture content to around 40.

6. Materials with a moisture content of about 40% are produced into columnar semi-finished products through a granulator, which are then shaped into spherical granular semi-finished products through a shaping machine. They are transported by a conveyor belt to a tubular dryer for low-temperature drying, and then screened and cooled by a cooling screening machine to reduce the moisture content to between 15 and 30. They can also be coated and packaged as needed;

7. The finished particles are transported to the packaging workshop through bucket elevators and finished product conveyor belts, and are packaged using automatic measuring packaging scales and manually stacked.

The construction of an organic fertilizer production line has a market opportunity. Nowadays, people are pursuing a high-quality life, and their pursuit of food quality is also increasing. Under the strong call of national policies, more and more farmers are applying organic fertilizer, which has a long-lasting effect and contains various nutrients that crops need. Maintaining fertilizer and water can also prevent and control diseases and pests. The small organic fertilizer production line has a very broad profit margin and is an ideal project.
