Is there dust pollution in the chicken Organic fertilizer production line? How to solve the problem of dust removal? When Organic fertilizer production line equipment is used to make Organic fertilizer, a small amount of dust will also appear on individual sites, which requires that these dust be removed.

1. In the whole Organic fertilizer production line, when the materials are dried, a certain amount of fine dust will be produced. We can extract these dust for precipitation and filtration through the cyclone dust collector or water curtain dust collector, which solves the problem of dust. Because of limited funds, friends can build a small dust chamber next to the dryer, and pump the dust into the dust chamber through the fan for static setting.

2. During the construction of Organic fertilizer equipment, most of them use organic wastes and perishable substances. So the storage and unloading of raw materials will generate odor. In addition, the storage sites for raw materials, auxiliary materials and compost, as well as the platform between fermentation facilities accessed by Cart, etc. It can produce dust and unpleasant gases. Although auxiliary materials such as rice husks and sawdust do not produce unpleasant gases, they produce a large amount of dust when unloaded.

3. When the shredder in the Organic fertilizer equipment is used to crush rice husks, dust and water vapor will also be generated when the crushed rice husks are transported. When crushing and pruning, if a shear crusher is used, there is basically no dust generated. However, if high-speed rotary crushing and air conveying are used to crush and prune, a considerable amount of dust and noise will be generated.

4. In the mixing equipment, various raw materials are fed into the mixer, especially during the discharge of low moisture content compost returns and mixed raw materials, which can also generate odor and dust.

5. In the fermentation process, the decomposition of organic matter produces ammonia gas. Through the input of raw materials into the fermentation facility and the discharge of compost through the fermentation facility, odor and dust are generated during repeated operations in the secondary fermentation tank. The decomposition of organic matter will cause the temperature of raw materials to rise and generate a large amount of water. In the process of repeated operation, water vapor, dust and gas will be mixed together, resulting in white fog in the fermentation room of Organic fertilizer equipment. The odor and water vapor generated during the fermentation process will significantly decrease with the end of the first fermentation, and will basically disappear upon the completion of the second fermentation. The decrease in moisture in compost is accompanied by a decrease in moisture, which in turn generates dust. During the repeated use of secondary fermentation facilities, water vapor and dust will be generated simultaneously.

6. After the chicken organic fertilizer Organic fertilizer production line is used for a long time, some dust will accumulate. If the dust is not cleaned in time, the use effect of the equipment will be affected. The dust pollution on the chicken organic fertilizer Organic fertilizer production line may be caused by high potential energy difference.

Utilize transportation equipment with good sealing performance to reduce the height difference and inclination of the unloading logistics, and set up flow separation facilities as much as possible. Not only can it enhance the flexibility and efficiency of the configuration between various operations, but it can also reduce scattering and dust. Utilize exhaust systems. In order to prevent dust from causing more pollution, indoor dust can also be removed through the exhaust system, which means removing indoor exhaust gas.

The chicken organic fertilizer Organic fertilizer production line will send all kinds of high humidity and high viscosity organic wastes (such as livestock organic fertilizer, chemical, paper making, brewing, food organic waste residue) that need to be dried into the high humidity material dryer through the conveying system, which will be lifted by the special board on the inner wall of the cylinder. The rapidly rotating mixing wing in the middle of the cylinder repeatedly crushes the wet material, allowing for sufficient heat exchange between the material and the high-temperature hot air with slight negative pressure. Due to the combined effect of the cylinder inclination angle and introduction, the material slowly moves forward and flows out from the tail; The exhaust gas is discharged up to standard through cyclone dust removal and water bath dust removal.

Some farms use water to clean up feces, so the water content is relatively large, and some farms use manure cleaning machine, the water content is less.
If the moisture content in raw materials is too high, dry and wet separators can be used to reduce water content, or straw can be added to control water content. When the moisture content is about 55%, fermentation can be started. The simplest way to check the moisture content is to hold it by hand. If the water flows along the finger joint, it means that the moisture content is too high. If it is kneaded into a ball, it means that the moisture content is low. The best way to check the moisture content is to hold it by hand without overflowing.
Fertilizer production process according to the product to add organic fertilizer microbial agent, no requirement can be added. If you want to speed up the fermentation of raw materials, you can add organic fertilizer starter. During the fermentation process, the fermentation temperature should be controlled at all times to reach about 70 degrees, and the compost windrow turner should be used to flip until the fermentation is completed.

After fermented and decomposed, pig manure can be crushed by organic fertilizer grinder. If it is to produce powdered organic fertilizer, it can be directly packaged and stored. If the production of granular organic fertilizer, organic fertilizer granulator should be used for granulation, and then through the organic fertilizer screening machine, organic fertilizer dryer and other equipment to better process, improve the finished product quality of pig manure organic fertilizer. 

The production of organic fertilizer mainly includes: 1. Raw material preparation; 2 fermentation and ripening; 3. Granulation and molding; 4 quality control. In raw material preparation: chemical analysis and crushing of raw materials are required. When mixing raw materials, it is also necessary to adjust water content, carbon nitrogen ratio and pH. In the process of fermentation and decomposition: it is necessary to inoculate fermentation bacteria, aerate to ensure that the reactor contains appropriate oxygen, and flip to control the reactor temperature and promote the emission of water. Fermented and decomposed organic fertilizer can be directly applied to field crops or granulated. In the granulation and molding process: it needs to go through 7 steps: crushing, batching, mixing, granulation, drying, functional bacteria (sometimes added) and cooling. The granular organic fertilizer is generally used for flowers, fruits and vegetables and greenhouse crops. In order to ensure the quality of organic fertilizer, it is necessary to carry out quality control, detect the relevant indicators of organic fertilizer, and then judge whether it is qualified according to the standard of organic fertilizer.

In the trend of modern agriculture,the small-scale disc granulator is becoming more and more important.The application of organic fertilizer is no longer limited to a small expermental field.Now many agricultural users are proving that the small-scale disc granulator is more productive in colleges and universites.We can know that the modern organic fertilizer has the characteristics of pollution-free and pollution-free through the comparsion of organic fertilizer,inorganic fertilizer and other fertilizers.It can be optimized the physical and chemical structure of land can also enhance biological activity.Organic fertilizer machine is to be designed for the production of organic fertilizer.
Organic fertilizer itself is formed by the remains of animals and plants or their metabolites.For example,feces and urine metabolites.It is rich in nitrogen,phosphorus and potassium.It can provide nutrients for the farmers very well.Mover,most of these ingredients can be well absorbed and help the crops grow more well.Now organic fertilizer has the characteristics of pollution-free and pollution-free.Don’t worry about polluting the land.Better the sutainable production of agriculture has been realized.
In order to better understand the small-scale disc granulator,let’s talk about the advantages of organic fertilizer and its precautions.Organic fertilizer can effectively improve the physical and chemical structure of the land,which we have mentioned before.There are also achievements in improving the output of crops.Moreover,organic fertilizer can be applied together with other fertilizers,which can greatly improve the benefits of fertilizer.It is better than the previous farmyard manure.It can evenly distributed on the crops to promote the uniform absorption of the crops.It is also more convenient to use.When the organic fertilizer granulator,which it is to be made by using the fertilizer granulation machine to finish the granulation process,releases the organic fertilizer,it should also pay attention to the amount.It should be put in accordance with the actual situation.In addition,in the growth process of the agricultural crops,it must be paid attention to processing the organic fertilizer and then using it.In this way,it can be used.It can get rid of the germs brought by itself,so that it will not pollute the land and can get rid of these germs more scientifically.
So how do cow dung make organic fertilizer?
There are many raw materials for the production of bio organic fertilizer,which can be divided into the following categories:
1.Agricultural wastes,such as straw, soybean meal, cotton meal, etc. 2. Animal manure: such as chicken manure, cattle, sheep, horse manure, rabbit manure; 3. Industrial wastes: such as distiller’s grains, vinegar grains, cassava dregs, sugar dregs, furfural dregs, etc.; 4. Domestic wastes: such as kitchen garbage, etc.; 5. Urban sludge: such as river sludge, sewage sludge, etc.

Characteristics of bio organic fertilizer

The ecological organic fertilizer has complete nutrient elements, which can improve the soil and improve the soil hardening caused by the use of chemical fertilizer. Improve the physical and chemical properties of soil, and enhance the ability of soil water conservation, fertilizer conservation and fertilizer supply. The beneficial microorganisms in bio organic fertilizer enter into the soil and form a symbiotic and proliferative relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, play a collaborative role in the community, beneficial bacteria produce a large number of metabolites in the growth and reproduction process, promote the decomposition and transformation of organic matters, and directly or indirectly provide more for crops Plant nutrients and irritants to promote and control crop growth. Improve soil porosity, permeability and exchange, plant survival rate, increase beneficial bacteria, soil microorganisms and population. By the way,the flat die granulator machine is usually to be used to make bioorganic fertilizer granulator,besides these granulator machine,the rotary drum granulator machine also can be used to produce the fertilizer granulator.At the same time, the advantage of beneficial bacteria in the formation of crop root system can inhibit the propagation of harmful pathogens, enhance the ability of crop resistance to stress and disease, reduce the disease index of continuous crops, and the continuous application can greatly alleviate the continuous cropping obstacles. Reducing environmental pollution is a kind of environmental protection fertilizer, which is safe and nontoxic to human, animal and environment.

Why are fertilizers being used less and less? In the early days, farmers had a lack of understanding of fertilizers. The use of fertilizers has a significant effect, resulting in dependency. But later it was discovered that the soil environment was getting worse and worse, and the effect of chemical fertilizers was brief and obvious, but the damage to the sudden later stage was relatively large. Later, farmers generally realized the benefits of Manure.

Pig manure itself is a good farmyard manure, which is good for making Manure and green ecological planting. Pig manure contains 15% organic matter, low total nutrient content, 0.5~0.6% nitrogen, 0.45~0.5% phosphorus and 0.35~0.45% potassium. Pig manure is fine in texture and complex in composition, including protein, fat, organic acid, cellulose, Hemicellulose and inorganic salt. Pig manure contains a large amount of nitrogen, with a small carbon to nitrogen ratio (14:1), and is generally easily decomposed by microorganisms, releasing nutrients that can be absorbed and utilized by crops. If you directly come out of the pigsty and land on crops, it will have negative effects such as root damage, diseases, and grass damage.

Process flow of pig manure Organic fertilizer production line:

1. After mixing pig manure raw materials with plant straw for fermentation, it is recommended to use a ground tipping machine for ground stacking, or a trough tipping machine for feeding materials in the fermentation tank. During fermentation, the raw materials need to be flipped at irregular times.

2. The fermentation time varies depending on the temperature in different regions. Generally, the fermentation time is 7-15 days, and after complete fermentation and maturation, it is directly collected by forklift.

3. Forklifts are used to transport fermented pig manure raw materials to the silo, where the raw materials are sent to the Organic fertilizer grinder by belt conveyor for crushing.

4. The crushed raw materials are sent to the Organic fertilizer mixer through the belt conveyor for uniform mixing, and then sent to the Organic fertilizer granulator.

5. The raw materials are made into granules by the Organic fertilizer granulator, and then directly sent to the Organic fertilizer dryer. The granules are dried to facilitate transportation and storage.

6. In order to prevent Manure particles from caking, dried particles need to be sent to Organic fertilizer cooler for cooling to increase their particle strength.

7. The cooled particles are sent to the Organic fertilizer screening machine for screening, the unqualified particles are sent to the granulator for re granulation, and the qualified particles enter the next process.

8. After screening, the qualified particles are packaged into bags using an automatic packaging machine or manually, and placed in a dry and ventilated place to complete the entire production process.

Pig manure water is the most difficult to deal with in pig farms. The organic content of pig manure water is high and the concentration is high. If no effective measures are taken, it will lead to persistent stench and bring serious impact on the environment.
The cattle farming industry in China is growing with the increasing consumption of beef cattle, and processing cow manure into organic fertilizer is also the main means for the cattle farming industry to treat cow manure. The quality of the cow manure organic fertilizer production line also determines the quality of the finished cow manure organic fertilizer. High quality cow manure organic fertilizer has higher nutritional components, and higher prices and profits. Therefore, when choosing equipment for the cow manure organic fertilizer production line, we should not only pay attention to the price of the equipment, but also pay more attention to the manufacturing process and good operation performance of the organic fertilizer equipment to avoid causing problems during the production process and affecting production efficiency.With the strict supervision of environmental protection, the illegal consequences of illegal discharge are very serious; however, if we want to build facilities to meet the discharge standards, the investment is huge, and the operation cost is high, most of our current situation is impossible to complete.

Technology of rapid fermentation of pig manure into organic fertilizer
For the first fermentation of pig manure, pig manure with water content over 80% should be simply mixed with some forage (rotten grass is the best, crushed straw and dry cow dung can also be used), or one layer of pig manure and one layer of forage can make the water content of pig manure be about 60%, which can be stacked into strips about 1 m high and 1.2-1.5 m wide. During the mixing process of pig manure and forage, the activated bacteria should be sprinkled and the film should be covered in low temperature season. 
Generally, the temperature will rise to 70-75 ℃ in about 24 hours, and the organic fertilizer machine will turn and ventilate properly. After 72 hours, the temperature will drop. At this time, the odor will be basically eliminated, and the fermentation will be completed in 10-15 days. If the compost was turned once on the fifth day of fermentation, the effect would be better. The pig manure after fermentation becomes organic fertilizer with water content below 40%.
Through the above-mentioned treatment technology, the environmental protection problems of pig farms and the recycling problems of manure can be easily solved without increasing the investment of facilities, and the allowable cost is low.

Two in one NPK fertilizer granulator is a special granulator for fertilizer production. It is also known as an internal rotating agitator because its internal structure is made up of many helical mixing teeth. The granulator adopts wet granulation, so it is suitable for granulation of raw materials with high water content and is widely used for granulation of organic fertilizer chemical raw materials.

Due to its high granulation rate, stable operation, strong and durable equipment and long service life, it has been selected as the ideal product by the majority of users. Our company has developed and produced more than 60,80,100 specifications of spiral tooth granulator, and can develop and produce other types of stirring tooth pelletizer according to user requirements. The shell of the granulator is made of thick seamless steel pipe, which is sturdy and durable without deformation. In addition, the stable base design makes its operation more stable. In the fertilizer production line processing, the efficiency is very high.

Working principle of two in one NPK fertilizer granulator

Two in one NPK fertilizer pelletizer uses high-speed rotating mechanical stirring force and generated aerodynamic force to continuously realize the mixing, granulation, spheroidization and densification of fine powder materials in the machine, so as to achieve the purpose of granulation. The particle shape is spherical, the sphericity is 0.7, the particle size is generally between 1-83mm, and the granulation rate is 90%. The particle diameter can be adjusted according to the material mixing amount and spindle speed. The lower the mixing amount is, the higher the rotational speed is, the smaller the particle is, and vice versa.
Scope of application

This new type of fertilizer granulator is especially suitable for the granulation of light and fine powder materials. The finer the basic particles of the fine powder material, the higher the sphericity of the particles, and the better the quality of the particles. And the strength of the granules is higher than that of the disc granulator. Typical application materials for this machine: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc.

Manure, commonly known as farmyard manure, consists of various animal and plant residues or metabolites, such as human and animal dung, straw, animal residues, slaughterhouse waste, etc. Carbon containing materials mainly derived from plants and/or animals, applied to the soil to provide plant nutrition as their main function. It is processed from Biogenic substance, animal and plant wastes, and plant residues, eliminating toxic and harmful substances, and rich in beneficial substances, including a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. It can not only provide comprehensive nutrition for crops, but also has a long fertilizer effect. It can increase and renew Soil organic matter, promote microbial reproduction, improve the physical and chemical properties and biological activity of soil, and is the main nutrient for green food production.

With the continuous strictness and strengthening of environmental protection in various regions, many areas have blocked the external discharge ports of breeding farms and are not allowed to discharge from them. Farming continues, and the septic tanks are becoming increasingly full. Even increasing the number of septic tanks is still a drop in the bucket.

The technological process of Organic fertilizer production line to process farm manure into fertilizer:

1、 Raw material and ingredient ratio

Mixing manure with crop straw depends on the moisture content of sheep manure. According to the fermentation process, the moisture content is required to be within 45%, which means that when the material is kneaded into a ball, water can be seen, but water will not drip down. If the ball is loosened, it will disperse. Then, add corn flour and determine the required bacterial strains. The reason for corn flour is to increase its sugar content for promoting rapid fermentation of bacterial strains.

2、 Material mixing

Add the configured materials to the material mixer for mixing, ensuring that the mixture is uniform, transparent, and does not leave any lumps.

3、 Material fermentation

Then, the mixed materials are stacked in a fermentation tank or tank with a width of 2-6 meters and a height of 1.0-1.5 meters. Every other day, the flipper and stacker flip and flip repeatedly. Usually, in a fermentation tank, the temperature will increase after 2 days of stacking, there will be no odor after 2 days, it will become fluffy and loose after 3 days, compost will emit a fragrance after 2 days, and it can become fertilizer after 15 days.

4、 Fermentation process

1. In the fermentation tank for 2 days, the temperature will rise to 60 ℃ -80 ℃, which will sterilize and eliminate pests.

2. On the the fourth day in the fermentation tank, eliminate the odor; Then on the seventh day, the material in the tank will become loose, dry, and covered with white hyphae.

3. On the ninth day of fermentation in the tank, Jiu will emit a fragrance that is basically similar to the aroma of koji.

4. On the tenth day of fermentation in the tank, the material will be fully fermented and matured.

5. It represents the end of the fermentation stage, and materials can be removed to the next process using a forklift or other means.

5、 Granulation and drying process

The materials moved by the forklift to the crushing process are crushed by a semi wet and high wet material grinder, and then mixed by a mixing mixer. They are transported by a conveyor to the Organic fertilizer granulator for granulation. The particles made are sent by a belt conveyor to a dryer for drying, and then cooled by a cooler, and then sent by a conveyor to a screening machine for screening

6、 Screening and packaging

More than 95% of the particles that meet the requirements will enter the next process, while about 5% of the particles will be transported to the Organic fertilizer crusher for further crushing and granulation. The particles that meet the standards will enter the coating machine for coating, which can maintain nutrients. After coating, the automatic packaging machine will be used for packaging. In this way, the fecal Manure is processed and packaged, and can be put into storage for sale.

The profit of processing chicken manure organic fertilizer is different according to the type of chicken manure organic fertilizer processed (classification of various auxiliary materials added). The profit of large probability is between 120 yuan and 400 yuan per ton. Of course, if it is powdery organic fertilizer, the profit margin will be lower, and the profit margin of higher quality organic fertilizer will increase greatly.

The profit of a ton of chicken manure organic fertilizer is inseparable from cost and revenue. The cost of one ton of chicken manure organic fertilizer includes organic fertilizer machine, plant construction, labor and other expenses. As mentioned above, affected by the performance of organic fertilizer, the price of organic fertilizer per ton is different.
Small organic fertilizer production line processing plant is divided into two types: powder line and particle line. Compared with powder line, granular organic fertilizer equipment needs more equipment and more investment. Therefore, the powder organic fertilizer on the market is usually cheaper than the granular organic fertilizer, which can be sold for 400-600 yuan / ton, the granular organic fertilizer can be sold for 600-1000 yuan / ton, and the price of special organic fertilizer is about 2000-3500 yuan / ton. Some high-quality organic fertilizers cost thousands of yuan per ton. 

Simple organic fertilizer processing can be completed using organic fertilizer composting machines and organic fertilizer granulators, suitable for small processing plants with low production process requirements that can be sold with simple processing. The characteristic is small production and sales, low investment cost, and low risk. If more raw materials need to be processed, more organic fertilizer equipment needs to be invested. However, the quality of the produced organic fertilizer will also be better, and the profits will also be considerable. Those without experience can start from small organic fertilizer processing plants, accumulate some experience, and then expand the production scale according to the situation.

As a fertilizer machine enterprise which has been operating for many years, our NPK fertilizer production line and organic fertilizer equipment have been sold all over the world, and now they are loved and supported by customers in various countries.

Generally, trough compost turner machine is recommended for the fermentation process of feces. Materials can be stacked in the tank to a higher height, which can save space and turn the pile efficiently. The overturning and throwing machine can move from one fermentation tank to another through a shift truck, and the tank type tipping machine can be used for multiple fermentation tanks. The equipment can be used in the environment temperature of – 20 ℃ ~ 50 ℃. It has strong adaptability to the characteristics of fermentation materials.

According to the particularity of fermentation materials, compost turning machine is made of corrosion-resistant materials, so it is more durable. It is a popular model with reasonable structure, high efficiency, low energy consumption, high automation, easy to use and low cost. Of course, users can also consider the relatively flexible bar and stack fermentation, which has no special requirements for the site, but occupies a much larger area than the tank fermentation.
Organic fertilizer equipment can effectively solve the environmental pollution caused by organic waste in industries such as livestock and poultry breeding, reduce the eutrophication of surface water caused by pollution, improve the safety and quality of agricultural products, and lay a good foundation for human comprehensive consumption of green and organic food. The ecological and environmental benefits are quite significant. The pig manure organic fertilizer production line has a high degree of automation and smooth production rhythm, which not only improves work efficiency but also saves a lot of manual labor. Pig manure organic fertilizer can improve the chemical and biological characteristics of soil, improve soil water retention, fertilizer retention, and permeability, and the profit per ton ranges from 300 to 500 yuan.
