In addition to producing meat, poultry, eggs and other products, the livestock industry also produces fecal pollution. In the early agricultural system, manure was a source of fertilizer for agriculture. With the rapid development of animal husbandry towards intensification and scale, a large breeding area has a huge amount of manure production, and the local land cannot be digested, which will have an impact on the environment. Nowadays, the constraints of land and environmental capacity are becoming increasingly apparent, and the treatment of livestock and poultry manure has become a key issue affecting the sustainable development of the breeding industry.

Composting is an important technical means for achieving harmless disposal and resource utilization of organic waste, and it is also the main way to fertilize manure. During the composting process, under artificially controllable conditions, aquaculture manure is decomposed and synthesized by microorganisms to form stable humic substances (organic fertilizers), achieving the goal of harmless and resource utilization, which is in line with ecological benefits and economically effective.

The fermentation section requires the application of various effective equipment to regulate fermentation parameters. The application of organic fertilizer turner to operate the fermentation pile is the most common and effective method. The role of organic fertilizer turner in composting production includes stirring materials, adjusting the temperature of the material pile, improving the permeability of the material pile, adjusting the moisture content of the raw material pile, and implementing special requirements for composting technology.

After adopting a chain plate flipper, the fermentation workshop can be divided into a feeding area, a fermentation area, and a discharge area because the flipper moves the materials backwards at a fixed distance during the flipping process. The fermentation raw materials only need to be transported to the feeding area, and can be moved to the discharge area during the flipping process through a stacker. This is different from the all in and all out fermentation mode, which requires the use of a forklift to carry out material distribution and discharge work throughout the entire fermentation area.

Experiments show that bio-organic fertilizer can reduce the nitrate content of vegetables by 48.3–87.7% on average, increase the content of nitrogen, phosphorus and potassium by 5–20%, increase the content of vitamin C, and reduce the existing content. The increase in total acid, reducing sugar and sugar-acid ratio, especially in tomatoes, lettuce, cucumber, etc, can significantly improve the taste of raw food ingredients. The organic mixed fertilizer has complete organic and inorganic nutrients, balanced nutrition and high nutrient utilization rate, which can effectively improve the soil. This is the fertility trend in our country.

Organic fertilizer npk fertilizer production line: crushing->mixing->granulating->drying->cooling->coating->filtering->drinking sealing->finished product storage.

Organic fertilizer npk manufacturing process: The binder raw materials and other ingredients that must be proportioned are metered according to the proportioning requirements, and discharged into the high-efficiency multi-stage mixer with integrated elevator. Soon, the fully mixed material comes out of the mixer. In the silo, the feeding plate is uniformly and continuously fed and use the double roller granulator to obtain columnar particles; the particle polishing machine shapes the cylindrical particles into round particles, and sends them to the machine through the conveyor belt for drying, cooling and Inspection (three-in-one model), the parts are dried, cooled and tested at low temperature and large air volume (≤65°C) before the dryer, and then enter the cooling unit of the cooler, and the completely cooled material enters the end of the cylinder to place a centrifuge The screen machine and filter transport the filtered finished parts from the elevator to the finished product silo, and are measured by the packaging system and put into storage; the inspected large particles are crushed and returned to the granulation system; the filtered small particles can be made into small packages direct sales.

The combination of base fertilizer is the premise of soil cultivation. It is understood that the excessive use of organic fertilizer is only an individual phenomenon, and the amount of organic fertilizer in most shanties is generally insufficient. According to the data, the organic matter consumed by one mu of vegetables is about 2,000 kilograms, so applying a sufficient amount can make up for the consumed organic matter. It is generally recommended that the amount of organic fertilizer per mu should reach about 10,000 kilograms. You can choose high-quality livestock manure, rice husk manure, high-quality straw, etc. Of course, you can also use the npk manufacturing process to produce high-quality commercial organic fertilizer mixed fertilizer.

In order to ensure that the base fertilizer can adequately supply the nutrients for the growth of vegetables throughout the growth period, the method of mixing organic fertilizers with chemical fertilizers is often used in the base fertilizers. Use the npk fertilizer production line to mix 100% of the required phosphate fertilizer, 20%-50% of the potassium fertilizer, and 30%-50% of the nitrogen fertilizer into the organic fertilizer. The amount of chemical fertilizer should be adjusted according to the quality and quantity of the organic fertilizer used. On the one hand, adding biological bacterial fertilizer to the base fertilizer can better improve the soil and improve the absorption and utilization rate of nutrients; on the other hand, biological bacterial fertilizer can prevent root diseases and continuous cropping damage by bacteriostasis.

The production of high-quality organic fertilizer comes from excellent organic fertilizer raw materials and advanced production technology. The complete set of organic fertilizer production line equipment is generally: mixing mixer (various raw materials are crushed, proportioned and mixed in a certain proportion during the operation of the organic fertilizer production line), organic fertilizer production line. Granulators, tumblers, dryers, pulverizers, dust removal systems and other equipment, among which granulators are essential for the production of granular organic fertilizers, granulators include double roller granulator, disc granulators , drum granulator, roller granulator, etc.

Cow manure, as a high-quality organic fertilizer raw material, has broad application prospects. For the treatment of 10000 cow manure, it is necessary to use large-scale organic fertilizer production equipment to improve production efficiency and product quality.

There are various types of equipment for producing organic fertilizers, mainly including fermentation equipment, drying equipment, crushing equipment, screening equipment, and packaging equipment.

Organic fertilizer fermentation equipment is the core equipment for producing organic fertilizers, which converts organic matter in cow manure into stable humus through aerobic or anaerobic fermentation methods. The organic fertilizer drying equipment is used to reduce the moisture content of the fertilizer for subsequent treatment. The organic fertilizer crushing equipment and screening equipment are respectively used to crush the raw materials into appropriate particle sizes and screen out unqualified particles. Finally, the organic fertilizer packaging equipment packages the finished organic fertilizer for easy storage and transportation.

The required equipment output for the treatment of 10000 cow manure needs to be calculated based on specific production cycles, raw material moisture content, and other factors. Generally speaking, the annual output of large-scale organic fertilizer production equipment ranges from tens of thousands to hundreds of thousands of tons. When selecting equipment, factors such as equipment capacity, raw material processing capacity, floor area, and energy consumption need to be considered. Meanwhile, the selection and maintenance costs of equipment also need to be taken into consideration.

Compound fertilizers are divided according to their nutrient composition: fertilizers containing nitrogen, phosphorus and potassium are called binary compound fertilizers; fertilizers containing the three elements nitrogen, phosphorus and potassium are called ternary compound fertilizers; in addition to the three nutrients, they also contain Micronutrients are called multi-component fertilizers; in addition to nutrients, they also contain pesticides or auxins are called multifunctional multi-component fertilizers. Classification according to fertilizer composition: It is divided into solid multi-component fertilizer and liquid multi-component fertilizer, and solid multi-component fertilizer can be divided into granular, powder and crystalline forms.

Mixed fertilizer production line According to the production process, mixed fertilizer is a mixed fertilizer that is mechanically mixed into a certain proportion of several elemental fertilizers with relatively consistent granule shapes. Production can be completed using the npk organic fertilizer production line. The npk manufacturing process mainly includes feeder, disc mixer, chain crusher, double roller granulator, rotary drum dryer, rotary drum cooler, rotary drum screening machine, finished product warehouse, automatic packing machine, belt conveyor, dust settling chamber, heat exchanger.

Among them, the double roller granulator is the key equipment for compound fertilizer granulation. It has advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and is matched with the corresponding equipment to form a small production line that can form a certain continuous production ability, mechanized production, non-drying, room temperature production, product rolling and product quality meet the technical requirements of multi-component fertilizers.

In the npk fertilizer production line, various elemental fertilizers are processed into fertilizers by a certain process. During the mixing process, a small amount of liquid phase can be provided by heating and adding acid, and the economic liquid containing ammonia can be converted to water vapor and granulate each other under limited conditions. It can produce ternary compound fertilizer. Similarly, the addition of other nutrients or drugs can create a multi-functional compound fertilizer.

Firstly, there must be a workplace. The area of ​​organic fertilizer equipment is mainly related to the annual output, which is generally divided into the following categories:

An organic fertilizer processing plant with an annual output of 5,000 tons needs 1,000-1,500 square meters;

An organic fertilizer processing plant with an annual output of 10,000 tons requires 1500-2000 square meters;

An organic fertilizer processing plant with an annual output of 20,000 tons requires 2000-2500 square meters;

An organic fertilizer processing plant with an annual output of 30,000 tons requires 3,000-3,500 square meters;

An organic fertilizer processing plant with an annual output of 50,000 tons requires 5,000-6,000 square meters;

Secondly,choice of organic fertilizer equipment:

1. Determine the size of the organic fertilizer equipment: such as how many tons per year, or how many tons per hour, to determine the price.​​​​

2. Determine the shape of the particles, that is, what kind of granulator to choose: powder, column, oblate or standard circle. Commonly used organic fertilizer granulation equipment are: disc granulator, rotary drum granulator, wet granulator, double roller granulator, flat die granulator, ring film granulator. The choice of granulator should be determined according to the local fertilizer sales market.

3. Determine the configuration level of organic fertilizer equipment: the level of equipment configuration is different, the price of organic fertilizer equipment is different, the amount of labor is different, and the stable and high yield of organic fertilizer equipment is also different. Automatic packaging device, automatic dosing device, cyclone dust removal and water dust removal.​

4. Determine the type of fertilizer to be produced. Generally, there are 4 kinds of organic fertilizers, pure organic fertilizer, organic-inorganic compound fertilizer, bio-organic fertilizer, and microbial compound fertilizer. There are also subtle differences in organic fertilizer equipment, npk fertilizer production line, organic fertilizer production lines, and bio-organic fertilizer production lines. The lines are slightly different.

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.
