Process flow of organic fertilizer production line for manure treatment in livestock and poultry farms

In livestock and poultry farms, manure treatment is a crucial step, and the production of organic fertilizer is one of the important methods for converting these manure into valuable resources. The process flow is mainly divided into four steps: collection, separation, composting, and fermentation.

The first stage is the collection phase, where livestock and poultry manure is effectively collected and preliminarily separated. It is possible to separate livestock and poultry manure from urine through a centralized collection and separation system to reduce the generation of ammonia and odor, and improve subsequent treatment efficiency.

Then comes the composting stage, where the separated animal manure is sealed and stored, and organic waste is properly organized and stacked, supplemented by ventilation equipment to control temperature, humidity, and oxygen supply, accelerating the decomposition process of organic matter. During this process, it is important to maintain appropriate humidity and ventilation to avoid the generation of odors and harmful gases.

Finally, in the fermentation stage, after the completion of composting, the compost is subjected to secondary composting fermentation to further enhance the stability and efficiency of the fertilizer. This process requires attention to reasonable moisture control and temperature regulation to ensure the full decomposition of organic matter and the killing of harmful microorganisms.

Organic fertilizer provides organic matter to the soil, thereby providing the necessary nutrients for plants and helping to establish a healthy soil system, rather than destroying it. Therefore, organic fertilizers contain huge business opportunities, and with the gradual restrictions and prohibitions on the use of fertilizers by most countries and relevant departments, the production of organic fertilizers will become a huge business opportunity.

Most organic raw materials can be fermented into organic compost. In fact, after crushing and screening, organic fertilizer compost becomes high-quality and saleable powdered organic fertilizer.

What are the benefits of processing fertilizers on pig manure organic fertilizer production lines?

Pig manure organic fertilizer not only adds a lot of organic binders, but also decomposes many organic matter into organic binders with the help of microorganisms, which greatly increases the adsorption surface of the soil, produces many binders, and binds soil particles into organic binders. The stable particle structure improves the water retention of the soil. The ability to maintain fertilizer and breathability, regulate soil temperature.

The pig manure processing organic fertilizer granule production line is mainly composed of eight parts: quantitative conveying, crushing, screening, double roller granulator, drying, cooling, finished product screening and packaging. The configuration of the small pig manure organic fertilizer equipment only needs a pulverizer, a mixer, a pair of rotary drum granulator, a screening machine and a packaging machine to complete the production.

The production benefits of pig manure organic fertilizer include ecological and social benefits. The cost (complete cost) of organic fertilizer per ton is about 250-400 yuan, and the average ex-factory price is 700-1200 yuan / ton. According to the average price of the organic fertilizer industry and Profit calculation. The project has strong post-production profitability.

Ecological benefits: The organic fertilizers produced are rich in organic matter and plant active ingredients. Active ingredients can improve the biological, physical and chemical properties of the soil, reasonably improve and enhance the use rate of chemical fertilizers, improve the disease resistance of crops, and reduce pesticides. .The application amount of chemical fertilizer is beneficial to improve the groundwater pollution of crops caused by excessive application of chemical fertilizer, and the quality declines. It is good for the sustainable development trend and ecological benefits of environmental protection and agriculture.

Social benefits: The production and construction of organic fertilizers is conducive to improving soil, improving soil fertility and utilization of nutrient resources; making full use of the local rich agricultural and animal husbandry organic waste resources to promote local economic development; using products can reduce farmers’ production costs. Increase crop production, increase farmers’ income, promote the industrialization of fertilizer production, and promote the development of related industries.

How is the organic fertilizer production line made into granules?

fertilizer granulator May 11, 2024

The organic hypertrophy obtained by biological fermentation is mostly coarse powder or irregular small pieces, which is inconvenient to use, especially to machine seeding in large area. Making these organic fertilizers into spherical granular organic fertilizers is the key to promote the use of organic hypertrophy areas.

The coarse powder or irregular small pieces of organic fertilizer after biological fermentation are characterized by high moisture, loose and many fibers. The existing technologies for preparing spherical granular organic fertilizer from coarse powder or irregular small pieces of organic fertilizer after biological fermentation are mainly as follows:

1. Some manufacturers use the traditional disc fertilizer granulator or rotary drum granulator, need to dry and crush the coarse powder or irregular small pieces of organic fertilizer into very fine (more than 100 mesh) powder, and then add binder and inorganic fertilizer, and the amount of binder and inorganic fertilizer in organic fertilizer can not be more than 30%. Although this method can make spherical particles, due to processing The organic fertilizer in the process will be first crushed by sufficient precipitation, then granulated with water and then dried, repeated for many times, so the processing cost is quite high. Moreover, due to the low density of organic fertilizer, the particle strength is low, which is not conducive to storage, transportation and machine seeding;

2. Some manufacturers first dry the organic fertilizer until the moisture content is only 20-25%, and then use the flat die extrusion granulator or the double roller granulator to extrude the dried organic fertilizer into columnar or flat spherical particles. Although this method is more convenient to use, it is not suitable for machine sowing, and it has poor appearance and poor sales;

3. Some manufacturers will first use the flat die extrusion granulator to extrude into short cylindrical particles (due to high moisture content and high fiber content, the columnar particles also have certain plasticity), then polish and shape them into spherical particles, and then dry, cool and screen the spherical particles to obtain qualified particles. In this method, raw materials do not need to be treated, the moisture sequence is reduced step by step, and the production cost is greatly reduced, However, there are some fatal weaknesses in this method, that is, organic fertilizer is easy to arch, block and bond, with small output and high power consumption in extrusion process. 

The process and price of producing organic fertilizer from livestock and poultry manure

fertilizer granulator May 11, 2024

Powdered organic fertilizer is commonly used to improve soil and provide the nutritional value components required for crop growth. When they enter the soil, they can also be quickly decomposed and release nutrients quickly. Due to the slower absorption rate of powdered solid organic fertilizers, powdered organic fertilizers have a longer storage time than liquid organic fertilizers. The use of organic fertilizers greatly reduces damage to plants themselves and soil environment.

The process flow of producing organic fertilizer from livestock and poultry manure:

1. Raw material ratio: Various animal feces such as chicken manure, pig manure, cow manure, biogas residue, or fermentable and fertilizer effective raw materials are prepared in a certain proportion;

2. Raw material mixing: Mix the prepared raw materials evenly to improve the overall uniform fertilizer efficiency of the fertilizer particles;

3. Raw material granulation: The evenly mixed raw materials are fed into a fertilizer granulator for granulation;

4. Particle drying: Feed the particles made by the granulator into the fertilizer dryer to dry the moisture inside the particles, increase their strength, and facilitate storage;

5. Particle cooling: The temperature of the dried fertilizer particles is too high, making them prone to clumping. After cooling, they are easy to pack, store, and transport;

6. Particle classification: The cooled particles are classified, and the unqualified particles are crushed and re granulated to screen out the qualified products;

7. Finished product coating: Coating qualified products to increase the brightness and roundness of particles;

8. Finished product packaging: Bag the finished product particles and store them in a ventilated place.

The above are the process steps of the organic fertilizer production line for the treatment of livestock and poultry manure. Of course, the specific operation also involves different processes and equipment choices, which need to be adjusted according to the specific site and actual situation. Because the production capacity requirements of each project, the ground processing site, and the configuration of the entire set of organic fertilizer production equipment are not fixed, there are often many different situations, so the specific price depends on the situation. You need to consider factors such as equipment power, production capacity, automation level, and additional functions. For some special equipment or high-end large-scale production lines, the price may be higher. It is recommended that you conduct market research and communicate with multiple suppliers before making a purchase to ensure that you can obtain the most suitable production line for your needs and budget.

The difference between granular organic fertilizer and powdered organic fertilizer production lines

fertilizer granulator May 11, 2024

Organic fertilizer production lines are generally divided into two categories, one is powder organic fertilizer production line, and the other is granular organic fertilizer production line, which is powder organic fertilizer production line.

1. Granular organic fertilizer is generally better than powdered organic fertilizer. Fertilizers with low water solubility should be crushed into small particles to ensure that they dissolve quickly and efficiently in the soil and are absorbed by plants. The control of organic fertilizer particle size is very important for the storage and transportation of fertilizers. Good granulation can make organic fertilizer not easy to agglomerate and have better transport performance. The organic fertilizer production line can add some inorganic ingredients, and the npk production line can also be used to improve the fertility of the organic fertilizer, while the powdery fertilizer can easily absorb moisture and agglomerate if inorganic ingredients are added.

2. The production of powdered organic fertilizer mainly includes livestock and poultry manure or domestic waste, sludge, wine tank, biogas residue and other alcohol and decomposed. The basic process of powdered organic fertilizer is dehydration, drying, fermentation, crushing, mixing and packaging. After these steps, the processing and production of powdered organic fertilizer is completed.

3. Granular organic fertilizer is not as simple as powdered organic fertilizer, and its production process requires further processing. Organic fertilizer granular fertilizer needs to go through the steps of alcohol growth, dehydration, drying, deodorization, crushing, mixing, mixing, double roller granulator, high temperature, cooling, packaging, etc. High temperature is required in the granulation process. In the process of producing granular bio-organic fertilizer at high temperature, powdered organic matter should be granulated first, and then microbial inoculants should be sprayed on the surface of the granules, which can not only ensure the granulation of organic fertilizer, but also ensure the survival rate of bacteria.

How to form a set of production technology for powdery organic fertilizer equipment

The advantages of powdery organic fertilizer

Powdery organic fertilizer is the organic fertilizer without granulation and drying, which occupies the absolute main market share. Compared with granular bio organic fertilizer, powdered organic fertilizer has the advantages of small investment, low production cost, less nutrient loss in the process of processing, low price and less ecological pollution, which is generally accepted by planting parks and fruit and vegetable bases. However, the powdered organic fertilizer has not been treated by disc granulator, and its shape is not beautiful enough, so it is not suitable for machine seeding and application.

Powder organic fertilizer production equipment

The production of powdery organic fertilizer is relatively simple. The main production machines are the following five parts: organic fertilizer turner, forklift, ration feeder, pulverizer, and screening machine (drum screener machine or vibrating screener).

Equipment and equipment need to be connected by belt conveyor to form a complete organic fertilizer production line

1. A belt conveyor above the crusher is connected to the large pieces of raw materials that have been screened.

2. A belt conveyor above the screening machine connects the fermentation raw materials.

3. A belt conveyor below the sieving machine connects the sieved finished material, and sends the finished material to the processing site for weighing and packaging.

4. The warehouse needs a conveyor for loading.

How much does the complete set of equipment for producing organic fertilizers cost?

fertilizer granulator May 11, 2024

The price of a set of organic fertilizer production equipment generally ranges from 200000 to 10 million yuan, and the specific price depends on factors such as the type, scale, technology, equipment quality, and brand of the fertilizer. At the same time, it is also necessary to consider transportation costs, installation costs, after-sales service costs, etc. Therefore, when purchasing organic fertilizer production equipment, one should choose appropriate equipment based on their own needs and budget, and comprehensively consider various factors to achieve the best economic and usage benefits.

1. The type of fertilizer is an important factor affecting the price of organic fertilizer production equipment.

Different types of fertilizers require different raw materials and production processes, so equipment prices may also vary. For example, the production equipment prices for organic fertilizers and bio organic fertilizers are generally higher because they require more raw materials and more complex production processes. The production equipment price of organic-inorganic compound fertilizer is relatively low because its production process is relatively simple, only requiring the mixing of organic and inorganic materials for granulation.

2. Scale is also one of the factors affecting the price of organic fertilizer production equipment.

Larger scale equipment requires larger venues, more workers, and more equipment, so prices are usually higher. Smaller devices are relatively cheaper, but their production is also relatively low.

3. The quality of technology and equipment is also a factor that affects prices.

Powder organic fertilizer processing equipment: flipping machine (used for composting process) – vertical crusher (crushing larger blocks in organic fertilizer) – screening machine (screening out non compliant organic fertilizers and returning them) – batching machine (adding other required nutrients to organic fertilizer in a certain proportion, which is an optional device) – horizontal mixer (mixing different materials evenly and using it in combination with batching machine) – single bucket packaging machine (used for quantitative packaging of finished organic fertilizer)

Granular organic fertilizer processing equipment: tipping machine – vertical crusher – drum screening machine (optional here) – batching machine and horizontal mixer (used in combination, belonging to optional equipment) – disc granulator – dryer and cooling machine – drum screening machine – round throwing machine (optional) – wrapping machine (optional) – single bucket packaging machine.

Different processes and equipment quality can lead to differences in production efficiency, product quality, and equipment lifespan. Therefore, equipment with higher prices usually adopts more advanced processes and high-quality materials to ensure production efficiency and product quality.
