With the development of animal husbandry, the scale of breeding farms has gradually expanded, which has also led to an increase in the amount of manure discharge. How to properly handle these feces and reduce their impact on the environment has become an urgent issue for the sustainable development of the aquaculture industry. The organic fertilizer processing equipment includes fermentation equipment, organic fertilizer granulation equipment, crushing equipment, organic fertilizer mixing equipment, screening equipment, cooling equipment, drying equipment, coating equipment, automatic packaging equipment and other process flows.

Solid manure treatment

For solid manure, composting technology can be used for treatment. By high-temperature composting, the organic matter in the manure is decomposed to kill pathogens and reduce odor. After a period of fermentation, compost products can be used as organic fertilizers for farmland fertilization, achieving resource recycling.

Liquid manure treatment

Liquid manure can be treated using anaerobic fermentation technology. By the decomposition of anaerobic microorganisms, the organic matter in liquid manure is converted into biogas. Biogas can be used as a clean energy source for power generation or heating, reducing the consumption of fossil fuels. Meanwhile, the fermented biogas slurry can be used for irrigation in farmland to improve soil fertility.

Ecological aquaculture model

Promote ecological aquaculture models and reduce the generation of manure through improvements in feeding methods. For example, using a dry manure cleaning method to reduce the amount of wastewater from washing the ground; Reasonably mix feed, improve animal utilization of feed, and reduce feed residue. In addition, the aquaculture and planting industries can be combined to form a circular agriculture model, which converts manure into organic fertilizer and is used for fertilization in farmland to achieve nutrient recycling.

With the increase of large-scale livestock and poultry farms, the total amount of manure put on farmland exceeds the capacity of farmland, and the random accumulation of manure that cannot find a way out has caused serious environmental pollution, which has attracted the attention of the government. The regulations stipulate that large-scale livestock and poultry farms must have facilities for the storage, treatment and utilization of manure and sewage.

The treatment of livestock and poultry manure is mainly carried out in accordance with the principle of “resource utilization”, and the comprehensive utilization of livestock and poultry manure is carried out by using the organic fertilizer npk manufacturing process. Livestock and poultry manure has resource attributes and can be returned to the field to make organic fertilizers. The fertilizer utilization of livestock and poultry manure organic fertilizer equipment can further increase the content of soil organic matter, improve the quality of agricultural products, and ensure the sustainable production capacity of farmland.

In the organic fertilizer npk fertilizer production line, after the pretreated livestock and poultry manure enters the organic fertilizer stirring and fermenting device for fermentation, an appropriate amount of nitrogen, phosphorus, potassium and other elements are added in a certain proportion to make the trace elements contained in the organic fertilizer production standard. And then go through the processing technology of stirring, pulverizing, forming, granulating, drying, packaging and so on. Granulation is an important link in the production of granular organic fertilizer. Extrusion granulation is simple and practical. After the compost after fermentation is adjusted to a moisture content of 20% to 30%, it can be directly entered into the granulator and extruded into cylindrical granules. The press granulator, the double roller granulator and the disc granulator are relatively small, with low production capacity and relatively cheap price, generally 30,000 to 50,000 yuan; the drum granulator is large in size and generally has a length of At about 10m, the production capacity is large, the smallest can reach 3t•h-1, and the price is relatively expensive, generally around 100,000 yuan.

The npk manufacturing process basically includes batching machine, pulverizer, mixer, double roller granulator, dryer, cooler, screening machine, automatic packaging machine, belt conveyor, etc. The computer control of the whole set of equipment of the organic fertilizer production line is programmable through the program controller (PLC). The organic fertilizer processing production line uses programmable memory to perform logical operations, sequence control, timing, counting and arithmetic operations on its internal stored programs. and other user-oriented instructions and control different types of machines or production processes through digital or analog input/output.

Programmable logic controllers have the following characteristics:

1. The whole set of organic fertilizer npk fertilizer production line equipment is easy to use and simple to program: using simple programming languages ​​such as ladder diagram, logic diagram or statement list, the system development cycle is short and on-site debugging is simple. In addition, the program can be modified online to change the control scheme without disassembling the hardware.

2. Powerful and cost-effective: There are hundreds of software elements in the computer for users to use, with powerful functions, which can realize very complex management functions. Compared with the relay system with the same function, it has a higher cost performance. PLC can be networked through communication to realize decentralized control and centralized management.

3. Complete hardware, easy for users to use and strong adaptability: computer and PLC products are standardized, serialized and modularized, and equipped with a complete set of different hardware equipment for users to choose. Users can configure the system flexibly and conveniently to form systems with different functions and scales. PLC installation and wiring are also very convenient. Typically, connection terminals are used to connect external wiring. The PLC has a large load capacity and can directly drive general solenoid valves and small AC contactors. Once the hardware configuration of the organic fertilizer processing production line is determined, the user program can be modified to easily and quickly adapt to changes in process conditions.

Pig manure has a fine texture and contains a lot of organic matter and nitrogen, phosphorus, and potassium nutrients. It decomposes slowly and is suitable as a base fertilizer. Pig manure is a treasure all over, with no waste. Even pig manure is an excellent fertilizer for agriculture.

A complete set of pig manure organic fertilizer production equipment and process flow: composting fermentation crusher, organic fertilizer crusher, mixing mixer, granulator, dryer, cooling machine, screening machine, coating machine, automatic packaging machine.

How much does a complete set of pig manure organic fertilizer production equipment cost? The price of equipment for producing 2000-5000 tons of organic fertilizer annually is about 150000 to 200000 yuan, and the price of equipment for producing 10000 tons of organic fertilizer annually is about 200000 to 350000 yuan

Many customers who are not familiar with organic fertilizer production ask this question. The equipment configuration of organic fertilizer production lines varies according to the different raw materials, and suitable plans can be made based on investment budgets. The prices of organic fertilizer production lines with different yields also vary. It is recommended that customers consider the amount of organic fertilizer production they want to invest in before making further inquiries, and then inform the manufacturer of the raw materials used for processing and production. This will provide an approximate price range for everyone, and then choose the appropriate production line configuration based on the expected investment.

The organic fertilizer production line has three configurations: high, medium, and low. Large fertilizer factories need to adopt a complete set of production configurations to produce finished products that meet market requirements in terms of appearance and nutrient content. They have a significant advantage in promoting finished organic fertilizers. Low to medium configuration organic fertilizer production lines are suitable for small and medium-sized fertilizer factories. The sales range of finished organic fertilizers is in nearby areas, and some processes in the organic fertilizer production process require manual completion.

The investment for the annual production line of 50000 tons of granular organic fertilizer using biogas and biogas residue is around 400000-5 million yuan. The main price difference lies in the production process of organic fertilizer. The production process of powdered organic fertilizer is simple, requiring less equipment compared to the granular organic fertilizer production line, and the price is lower.

The production line of biogas and sludge with an annual output of 50000 tons of granular organic fertilizer covers an area of:

Factory planning: 12000 square meters, including warehouse, office space, and factory area; The fermentation workshop covers an area of approximately 2400 square meters, and the warehouse covers an area of 4000 square meters.

The process flow of the annual production line of 50000 tons of granular organic fertilizer using biogas and sludge is as follows:

1. Fermentation:

Collect biogas residue raw materials, mix them with straw and other auxiliary materials to make compost, let it ferment, and use a composting machine to fully ferment the feces. Only by timely and evenly flipping can this be achieved. Some places are very dry now, while others are very humid, which will affect the quality of fermentation.

2. Crush and mix ingredients

Crush, mix, and mix the fermented materials with nitrogen, phosphorus, potassium, and other additives in a certain proportion through a material crusher and a horizontal mixer.

3. Raw material granulation

The crushed and mixed raw materials are granulated using a new organic fertilizer granulator.

4. Screening and return system

There are certain differences in the particle size of the granular materials output from the granulation and forming systems, which require screening and grading. The selected rotary screen requires low vibration, low noise, convenient screen replacement, and is equipped with a screen cleaning device.

It is recommended to equip an automatic material return system to screen out unqualified large and small particles, transport them out by a belt conveyor, crush them again, and send them to a granulator for continuous granulation, which helps to improve the continuous operation capacity of the production line.

5. Particle drying and cooling

The organic fertilizer dryer and cooler are used to further remove excess moisture from particles to meet the standard requirements for organic fertilizer moisture content.

6. Finished product packaging

The cooled granular material is transported to the finished product warehouse by a bucket elevator. Granular materials are quantitatively weighed and packaged through automatic packaging and weighing.

In recent years, with the rapid development of animal husbandry production and the continuous expansion of breeding scale, the amount of livestock manure, sewage and other breeding waste has also increased rapidly, leading to an increase in environmental carrying pressure and increasingly prominent pollution problems in livestock and poultry breeding. How to develop the animal husbandry industry in the context of environmental protection is one of the urgent problems that needs to be solved at present.

Large scale aquaculture plants perform solid-liquid separation on manure, ferment and return the treated manure to the field or make organic fertilizer. A new organic fertilizer plant will be built and put into operation, which will soon solve the problem of manure treatment for most nearby farmers.

The cow manure organic fertilizer processing equipment adopts advanced biological fermentation technology, which mixes cow manure with other organic matter such as straw, soybean meal, etc. in a certain proportion, and converts cow manure into organic fertilizer through the action of microorganisms. The emergence of this device not only solves the problem of cow manure treatment, but also turns waste into treasure and improves agricultural economic benefits.

High configuration: dehydrator, fermentation turner, semi wet material crusher, horizontal mixer, granulator, dryer, cooling machine, drum screening machine, wrapping machine, packaging equipment, belt conveyor, etc.

The use of cow manure organic fertilizer production lines can comprehensively recycle and reuse cow manure and breeding residues, improve the pollution of cattle farms, and provide fertilizer nutrients for the development of green agriculture. In addition, the production line technology and equipment functions of cow manure organic fertilizer are becoming increasingly perfect, which can effectively maintain the long-term development of organic fertilizer processing plants. The encouragement policies for the organic fertilizer industry in various regions provide direction for the development of the organic fertilizer industry. Therefore, the production line of cow manure organic fertilizer in large-scale breeding farms or independent organic fertilizer processing plants is a promising, green and environmentally friendly project with policy support.

The use of livestock manure to produce organic fertilizer is a more effective way of harmless treatment and resource utilization for large-scale pig farms. The organic fertilizer npk fertilizer production line is fermentation, crushing, stirring, granulation, drying, cooling, coating and packaging. If there is no organic fertilizer dryer or organic fertilizer coating machine, it can be packaged and stored or sold after cooling after granulation. In addition to the unnecessary granulation process of powder fertilizer, other processes are similar.

In the organic fertilizer npk manufacturing process, the organic fertilizer equipment for producing granular fertilizers requires organic fertilizer granulation equipment. The granulation of mixed fertilizers is an important process in the dry powder granulation process, which is not only related to the internal and external quality of the product, At the same time, it is related to the size of the output and the level of cost, and the granulation production process is not only related to the physical and chemical properties of the material itself, but also closely related to the form and mechanical properties of the granulation equipment. The main types of granulation equipment are disc granulator machine, drum granulator, twin-shaft granulator, double roller granulator and spray granulator dryer. Usually, drying is also required to make the fertilizer water and reach the national fertilizer standard, so as to meet the requirements of storage, transportation and application. At the same time, cooling equipment must be set up in actual production, and ventilation measures must be taken to force cooling.

The investment in organic fertilizer is not only in equipment, but also in site and infrastructure. Therefore, the investment in organic fertilizers ranges from tens of thousands to hundreds of thousands. The simple configuration of organic fertilizer equipment includes: fermentation equipment, organic fertilizer pulverizer, horizontal mixer, organic fertilizer granulator, drum screening machine and quantitative packaging scale.

The annual production line of 50000 tons of granular organic fertilizer mainly includes fermentation equipment, granulation equipment, and screening equipment.

Fermentation equipment

Fermentation is one of the key links in the production of granular organic fertilizers, and the main equipment includes a fermentation tank and a tipping machine. The fermentation tank is used to store materials for aerobic fermentation. The tipping machine is used to flip materials during the fermentation process, allowing them to come into full contact with air and accelerate the fermentation process.

Granulation equipment

Granulation equipment is the core equipment for the production of granular organic fertilizers, mainly divided into two types: disc granulator and agitator toothed granulator. The disc granulator uses a high-speed rotating disc to knead the fermented material into granules. The stirring teeth granulator uses the stirring teeth to force the material into particles, which has higher production efficiency.

Screening equipment

The screening equipment is used to screen the particles after granulation, and the main equipment includes a vibrating screen and a flat screen. The vibrating screen separates materials with different particle sizes through vibration, while the flat screen separates particles from unqualified products by swinging back and forth.

The main process flow of the granular organic fertilizer production line includes three stages: fermentation, granulation, and screening.

Fermentation process

The quality of the fermentation process directly affects the quality of the granular organic fertilizer. In this process, the raw materials are added to the fermentation tank, and through the irregular flipping of the stacker, the raw materials are fully in contact with oxygen for rapid fermentation. The fermentation time is generally 7-10 days.

Granulation process

The fermented material is fed into the granulation equipment and made into granules through a disc granulator or a toothed granulator. In this process, the size and shape of particles can be controlled by adjusting device parameters. After the granulation process is completed, the embryonic form of granular organic fertilizer has been formed.

Screening process

The screening process is the final and crucial step in the production process. The vibrating screen and flat screen will screen the particles after granulation, separating qualified particles from unqualified particles and impurities. In this process, it is necessary to select the appropriate mesh size according to the product requirements to ensure product quality.

The pollution generated by animal husbandry has become the main source of pollution in rural areas of China. The huge amount of data on livestock and poultry production cannot be ignored. If not handled properly, it will cause serious pollution to the environment. For example, if animal manure is not treated in a timely manner, it can cause serious pollution to surface water, groundwater, soil, and air.

The production equipment for cow manure organic fertilizer has a compact process layout, scientific rationality, advanced technology, energy conservation and consumption reduction, no three emissions, stable operation, reliable operation, convenient maintenance, and wide adaptability to raw materials. Adapting to various ratios of organic compound fertilizers, bio organic fertilizers, urban sludge, household waste organic fertilizers, etc., is a promotion project of practical environmental protection technology in the country.

The small-scale cow manure organic fertilizer production line has simple and complete configurations, which only require crushing, stirring, granulation, screening, and packaging processes. The entire set of equipment only costs tens of thousands of yuan, which is suitable for customers who do not have sufficient funds in the early stage. When there is sufficient funds in the later stage, they can add a flipper, dryer, cooler, and coating machine to form a complete organic fertilizer production line.

The price of organic fertilizer production lines varies depending on the equipment you need, ranging from tens of thousands to hundreds of thousands of yuan. This is mainly determined by the type of finished product and production volume you need. For example, if only one flipping machine is needed for aerobic fermentation treatment of livestock and poultry manure, it only requires tens of thousands of yuan to purchase a flipping machine. However, if you want to equip a complete set of equipment, the cost may start at tens of thousands of yuan.

With the rapid development of animal husbandry and planting, a large amount of livestock and poultry manure produced by large-scale farming has become a source of pollution if it is not disposed of in time. How to control these pollution sources from the source and utilize them rationally as soon as possible? Combining various factors, the ideal way is to use various organic fertilizer npk fertilizer production line and their processing equipment to recycle and ecologically utilize these wastes.

Composting is mainly divided into aerobic composting and anaerobic composting. At present, aerobic composting is mainly used. The composted manure has more stable nutrients, is more conducive to crop absorption, and can improve soil conditions. Therefore, farmers, small and medium-sized farms or farms mostly use this organic fertilizer equipment treatment mode.

The most common types of granulation are double roller granulator, disc granulator, tooth stirring granulator and drum granulator. The granules produced by each granulator are different, and the applicable materials have certain requirements. , the type of granulator can be determined according to the selection of raw materials.

In the organic fertilizer npk manufacturing process, the dryer dries the excess water in the organic fertilizer particles, which is convenient for material storage and not easy to deteriorate. In the production process of biological fertilizers, not only the water content of the granules after forming generally exceeds the index and needs to be dried at low temperature, but also the water content of the organic raw materials after fermentation is about 30% to 40%, and the water content of the granules after granulation is generally 15%between % and 20%, the fertilizer quality index requires that the moisture content is less than 14%, and it needs to be dried. The drying section is an indispensable and important process in the production process of biological fertilizers, which directly affects the output, quality and energy consumption. It is very important to choose the model and specification of the dryer reasonably and control the process conditions.
