organic fertilizer production line

At present, organic food has entered ordinary people’s homes in the market. With the strengthening of people’s health awareness, organic agriculture will usher in rapid development. As an important component of organic agriculture, the organic fertilizer market definitely has unlimited prospects. Because the investment in organic fertilizer processing plants is not significant and there is no technical threshold, as long as the quality is excellent, there is no need to worry about sales. Therefore, in current rural areas, running a small organic fertilizer processing plant is a good entrepreneurial project. Of course, before investing, it is important to consider the local sources of raw materials. In areas with more farmers, setting up such small factories would have lower costs and better prospects.

A complete organic fertilizer production line includes equipment such as fermentation tipping machine, grinder, feeding machine, horizontal mixer, organic fertilizer granulator, dryer, cooler, screening machine, weighing and packaging machine. This organic fertilizer production line can be used to produce granular and powdered organic fertilizers. Firstly, it is necessary to determine the product requirements for production. Currently, there are many types of organic fertilizers, organic inorganic compound fertilizers, bio organic fertilizers, granular organic fertilizers, and powdered organic fertilizers circulating in the market. Different products require different production line equipment, and small cow manure organic fertilizer production lines can be used to produce ordinary organic fertilizers. Whether the raw materials for organic fertilizer processing are chicken manure, cow manure, pig manure, or sheep manure, they can be used.

The machine equipment for making organic manure from cow dung can not only make organic manure from cow dung and sheep dung, but also the production line of general organic manure equipment is suitable for chicken dung, pig dung, cow dung, sheep dung, straw, medicine residue, furfural residue, humic acid, pond mud, domestic sludge of urban sewage treatment plant, etc. The selection of organic fertilizer production equipment varies slightly due to different raw materials.

Choosing the correct configuration of organic fertilizer production lines is also important for improving the efficiency of organic fertilizer production lines. Organic fertilizer production line manufacturers can achieve good sales in the fierce market competition, not only because of the excellent quality and unique design of the equipment, but also because our factory has professional technical personnel to guide the installation of the equipment and teach operating skills hand in hand. We also impart experience in daily maintenance of the equipment, so that the organic fertilizer production line can serve users to the maximum extent and bring considerable economic benefits.

Compared with similar products, the trough compost windrow turner has unique advantages in price and performance. The organic fertilizer plants in our country can not only save the cost, but also produce more environmentally friendly organic fertilizer, and have the capital to develop a larger market.

Trough type compost windrow turner is widely used in organic fertilizer plant, compound fertilizer plant, sludge waste plant, horticultural field and Agaricus bisporus planting plant. By using modern technology, livestock manure, agricultural and animal husbandry waste, urban domestic waste, filter mud, sludge, waste residue, distiller’s grains, etc. are harmlessly and synergistically treated to make them safe fertilizers for improving soil and improving crop quality. The organic fertilizer machine is an ideal equipment for transforming part of pollution sources and organic wastes into bio organic fertilizer.

Trough type compost windrow turner is suitable for aerobic fermentation. It can be used with solar energy fermentation chamber, fermentation tank and transfer machine. The function of one machine with multiple slots can be realized by matching with the mobile machine. The matching fermentation trough can not only discharge material continuously, but also batch discharge. High efficiency, stable operation, strong and durable, even flip. Control cabinet centralized control, can realize manual or automatic control function.  

1. Fermentation
The raw materials are collected and mixed with straw and chicken manure to make compost and ferment. In the process of fermentation and seed production, the use of a compost windrow turner can make the material fully ferment. Only by turning the pile in time and evenly can this be achieved. Some places are very dry, some places are very wet, which will affect the fermentation quality, so it is recommended to use a stacker.
2. Crushing and mixing of ingredients
The composted materials, inorganic fertilizers such as N, P, K and other additives are crushed, proportioned and mixed through a material crusher and a horizontal mixer in a certain proportion. The function of this system is to crush, mix and mix the composted materials, nitrogen, phosphorus, potassium, inorganic fertilizers and other additives in a certain proportion. According to many years of experience, the following suggestions are put forward for the equipment: the vertical crusher is used to crush the compost of cow manure, which is not easy to stick to the wall and block; the multi-layer turbulent chain hammer structure is used to improve the crushing performance; the continuous automatic batching system is suitable for the dynamic measurement and batching control of organic fertilizer raw materials; the mixing industry is equipped with a double shaft continuous mixer, which has good sealing performance, and the sticky and wet materials are not easy to be at the root of the mixing shaft adhere.

3. Granulation
A new type of organic fertilizer granulator was used to granulate the materials. The function of this system is to make particles from the materials which have been mixed completely. The advantages of the granulator are: wide adaptability of raw materials, wide requirements for raw material density and moisture content of raw materials, stable granulation, high forming rate of granules, uniform appearance of finished products, and no easy breakage;
Important steps in the production process of chicken manure organic fertilizer granulation.
4. Drying
Using the dryer, the granulated particles can be further removed to meet the standard requirements of moisture content of organic fertilizer.
5. Cooling
Cooling the granular materials with a cooler helps to store the particles with good quality. The hot particles from the dryer enter into the counter flow cooler from the top. The dry air enters from the lower part of the cooler under the action of the cooling fan, and carries out full cold and heat exchange with the hot and humid particles under the upper part. After cooling, the difference between particle temperature and ambient temperature is less than 5 ℃.
6. Screening
The unqualified particles are separated by drum screening machine, and transported to the crusher by belt conveyor, and then crushed and stirred for granulation again. The qualified particles are carried out in the next process.
7. Packaging
The qualified granules are packed by automatic quantitative packaging machine.
The whole organic fertilizer production process is connected by belt conveyor, bucket elevator or screw conveyor to realize the automatic production of organic fertilizer. The whole set of equipment only needs two or three workers to operate. 

The drum dryer is one of the important equipment in the compound fertilizer production line. The main function of the drum dryer is to remove excess moisture from the raw materials. The entire equipment is installed on a horizontal plane, with the feeding and discharging ends forming an inclined angle. By rotating the internal lifting plate, the material is transported from one end to the other end. The internal lifting plate evenly sprays the material inside the dryer, making it better in contact with hot air, Accelerate the evaporation of water.

The processed organic fertilizer particles to be dried are transported by a belt conveyor to the feed inlet of the feeder, and the particle material flows into the drum dryer barrel along the feeder chute. The feeder is embedded on the outer side of the drying cylinder. As the deceleration drive system drives the overall rotation, the granular material moves backwards with the rotation of the drying cylinder, and the feeder end is filled with heated hot air. Directly contact the material in the drying cylinder to evaporate its water vapor and dry it. During the drying process, the deceleration drive system is adjusted by a frequency converter to adjust the speed of rotation based on the degree of material drying. The material is dried dry, accelerating the value of the frequency converter to quickly pass through the integrated device of drying, cooling, and screening. If the drying effect is not good, lower the value of the frequency converter to make the drying, cooling, and screening integrated device rotate slowly, and the material stays inside for a longer time. The middle induced draft hood draws the dried water vapor out of the drying cylinder. Then, the dried material enters the cooling drum as it rotates. Under the action of the middle induced draft hood, natural air enters the cooling drum from the unclosed end of the cooling machine. As the cooling drum rotates, it picks up the material and directly lowers the temperature of the material to the natural temperature. Afterwards, the granular materials enter the drum screen, and the unqualified materials are screened out from the drum screen. The qualified materials directly enter the next packaging section.

The heat source of the dryer can be coal, electricity, natural gas, biomass particles, biomass oil, etc. The use cost of coal is lower, and the use cost of electricity is higher.

The current drum dryer is well made and has mature manufacturing technology. It not only has high output and lower energy consumption, but also uses high-temperature air generated by a hot air stove to evenly dry materials and is equipped with dust removal technology, which can better meet environmental requirements.

Adding non-toxic and harmless sawdust or coarse rice bran and other auxiliary materials (accounting for 10% – 15% of the total amount of fermented pig manure) in fresh pig manure, or try to mix chicken manure to regulate water content, ventilation and carbon nitrogen ratio, so as to control the water content of pig manure at about 60%. The C / N ratio is between 30 and 40.

The second is to add superphosphate, which accounts for 5% of the total fermentation material, to adjust the pH of pig manure to about 7.5. The additives must be mixed evenly with pig manure, stirred by organic fertilizer machine, and then stacked in a ladder shape in the pretreatment plant. The stacking trapezoid is 2m in width at the top and 3M in the bottom. The stacking strip is in the same direction as the gradient of the ground, so that the exudate can flow into the small ditch on the low side. The stacking time in the pretreatment plant was 7 days in summer and autumn, 10 days in winter and spring, and then it was fermented in fermentation trough.

The pretreatment process of pig manure organic fertilizer production process is as follows: fresh pig manure – adding fermentation bacteria – adding sawdust, rice bran, chicken manure – adding calcium superphosphate – uniform mixing – trapezoidal stacking for 7-10 days – sent to the fermentation workshop 

The conditions for pig manure fermentation and fermentation products

1. There should be some suitable microorganism.

2. To ensure or control the various conditions of microbial metabolism (medium composition, temperature, solubility, pH, etc.).

3. There should be equipment for microbial fermentation.

4. There should be methods and equipment for extracting strains or metabolites and refining them into products.

The organic fertilizer granulator machine is a key equipment for producing granular organic fertilizer. After granulation, powdered organic fertilizer can not only flexibly adjust the fertilizer formula, but also increase the price per ton by 1-2 times, making the profit of organic fertilizer greater.

Organic fertilizer granulator machines are divided into various types:

1. Agitator granulator: Utilizing the high-speed rotating mechanical stirring force and the resulting aerodynamic force, the fine powder material is continuously mixed, granulated, spheroidized, and compacted in the machine to achieve the purpose of granulation. The particle shape is spherical, with a sphericity of ≥ 0.7, a particle size generally between 0.3 and 5 millimeters, and a particle formation rate of ≥ 95%. The size of the particle diameter can be adjusted appropriately by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the higher the rotation speed, and the smaller the particle, and vice versa. Suitable for various organic fertilizer raw materials such as animal manure, sludge, clay, etc. Stirring teeth granulator

2. Disc granulator: The disc granulator has a novel and reasonable structure, with reduced weight and height. The process layout is flexible and convenient, suitable for the renovation of old factories. The inclination angle of the large plate can be adjusted. Adopting angle washers for flexible and convenient adjustment. The use of a unique unpowered combination scraper integration reduces auxiliary power consumption. The large plate is composed of a plate body and a plate section. Reduce the power of the main motor. The disc section can be adjusted up and down along the disc body. The end of the disc joint is an edge flange, which ensures that the material ball is not pulled or torn when it is discharged from the disc. A brand new desilting design, consisting of a combination of unpowered scraper for edge and bottom cleaning, angle cleaning scraper for corner cleaning, and unique disc processing technology. The desilting and ball forming effects are good, without large mud balls. The diameter of the feed ball is 90% between 3-5mm.

3. Roller extrusion granulator: Produced using a non drying room temperature process, this equipment has low investment and good economic benefits. The complete set of equipment has a compact layout, scientific and reasonable design, energy conservation and consumption reduction, no discharge of three wastes, stable operation, reliable operation, and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of various raw materials such as compound fertilizers, chemicals, feed, etc., with high product granulation rate. It can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.). Its advantage is that there is no need for drying treatment, and equipment investment is greatly reduced.

4. Organic fertilizer drum granulator: It is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation as well as large-scale production of high, medium, and low concentration compound fertilizers. The new generation rotary drum granulator has been developed by our company’s technical personnel, who have accumulated years of experience in the production of compound fertilizers. This machine has the advantages of high ball forming strength, corrosion resistance, wear resistance, simple operation, low energy consumption, long service life, and convenient maintenance. It is currently a relatively advanced granulation equipment in China.

Organic fertilizer is a good project for many people, but they don’t know much about this industry. Therefore, it needs to be investigated for a long time before it can be put into the production of organic fertilizer. The investment in the production of organic fertilizer can be large or small. If you only consider the treatment of livestock and poultry manure, a fermentation compost windrow turner can be used, Many small-scale organic fertilizer plants only need fermentation equipment, crusher, mixer, organic fertilizer granulator, screening machine and quantitative packaging scale to put into production. However, this mode of production requires a lot of human operation, such as the fermentation of raw materials in the early stage and the drying after granulation, which needs manual turning and drying.
The complete set of organic fertilizer plant production line only needs five or six people. It doesn’t need too much investment in human resources, but it needs to expand the investment in organic fertilizer machine. Investment in organic fertilizer is not only in equipment, but also in site and infrastructure. Therefore, the investment in organic fertilizer ranges from tens of thousands to hundreds of thousands.

The simple configuration of organic fertilizer machine includes: fermentation compost windrow turner, organic fertilizer crusher, horizontal mixer, organic fertilizer granulator, drum screening machine and quantitative packaging scale. These five equipment can make organic fertilizer put into production. If it is necessary to reduce the input of labor cost, several belt conveyors can be added. In this set of equipment, it is necessary to manually turn over the organic fertilizer fermentation and dry the organic fertilizer after granulation. This simple configuration of organic fertilizer machine is suitable for small organic fertilizer processing plants or farms. Under the premise of small equipment cost, the production of organic fertilizer can run normally.

Those who use simple and low configuration organic fertilizer machines are mostly farms, or those preparing to invest in small-scale organic fertilizer processing. Low configuration organic fertilizer machines are the most suitable for them, with less investment, smaller production scale and faster return on income.

In order to meet the requirements of environmental protection, the quality requirements of organic fertilizer products are not high, so low configuration organic fertilizer machine is used. The coating machine, round throwing machine, drying machine and cooling machine in the whole equipment can not be used. The round throwing machine and coating machine are used to improve the appearance quality of organic fertilizer particles. The drying machine and cooling machine are used to quickly remove the moisture in the organic fertilizer particles. If not, the manual air drying method can be adopted.
If the investment is less than 100000 yuan, the organic fertilizer production lines configured for each customer are different.

The low configuration of pig manure organic fertilizer production line only needs fertilizer crusher, fertilizer mixer, organic fertilizer granulator, screening machine and packaging machine. This belongs to the basic configuration, according to the actual needs and requirements of customers to add equipment. Therefore, the price of the whole pig manure organic fertilizer production line and chicken manure organic fertilizer production line ranges from tens of thousands to hundreds of thousands. At present, most of the automatic quantitative packaging machines in the domestic market are semi-automatic production, which requires manual bagging and personnel care when packaging. Generally, one automatic quantitative packaging scale needs two people to operate, which improves the interest of human resources in enterprise production.

The role of cow manure organic fertilizer production line equipment in the utilization of agricultural waste resources is well-known, and the achievements made are also evident to all. This processing mode of transforming agricultural waste into resource utilization not only solves the pollution problem of agricultural waste, but also realizes the recycling of agricultural resources, promotes the rapid growth of crops, and promotes the development of green agriculture.

The machine for processing cow manure into organic fertilizer refers to the equipment of the cow manure organic fertilizer production line, mainly including crushing machines, fermentation and deodorization machines, mixing machines, ingredient machines, drying and cooling machines, organic fertilizer granulation machines, screening machines, and finished product packaging machines.

The production process of granulation for cow manure organic fertilizer production line:

1. Add straw and rice bran materials in proportion to cow manure, sprinkle with fermentation bacteria, and then use an organic fertilizer flipping machine to flip and stir the raw materials to start heating and fermentation. Afterwards, flip and toss the raw materials every 1-2 days, usually around 15-20 days before fermentation and maturation.

2. By using a grinder and screening machine, fermented cow manure can be evenly crushed and impurities inside can be removed to obtain the finished powdered organic fertilizer.

3. Use an automatic batching system and mixer to pre mix the raw materials into a suitable granulation state. Generally, the water content is adjusted to about 40%, and corresponding auxiliary materials are added for uniform mixing.

4. The stirred raw materials are transported to the organic fertilizer granulator, which rotates and compresses the raw materials at high speed to form granular cow manure organic fertilizer. Then, a drying and cooling system is used to remove excess water from the particles to ensure sufficient strength.

5. The processed granular cow manure organic fertilizer is screened through a screening machine to obtain predetermined sized granular organic fertilizer. Small particles are returned to the granulator for remaking, while larger particles are returned to the feed crusher for crushing. Qualified particles flow into the automatic packaging machine and are packaged into bags.

Ecological agriculture, protecting and improving the ecological environment, preventing and controlling pollution, maintaining ecological balance, improving the safety and sustainable development of agricultural products. The normal development of agriculture and rural economy, as well as the close integration of environmental construction and economic development, meet the increasing demand for agricultural products by the people to the maximum extent, improve the stability of the system and the sustainable development of the ecosystem, and enhance the resilience of agricultural development.
