Author: organic fertilizer production line

The organic fertilizer production line that converts cow manure into fertilizer typically follows a standardized process aimed at ensuring safe and efficient conversion of cow manure into high-quality organic fertilizer. The following is a typical production process flow:

1. Raw material collection and pretreatment

Collect cow manure: Collect fresh or dry cow manure from cowsheds or pastures.

Solid liquid separation: If it is wet cow manure, perform solid-liquid separation first to reduce the liquid portion and facilitate subsequent processing.

2. Composting fermentation

Mix cow manure with appropriate amounts of organic materials such as straw, rice straw, sawdust, etc., adjust the carbon to nitrogen ratio (C/N ratio) to a suitable fermentation ratio (approximately 25:1-30:1) to promote microbial activity.

Form a compost pile and use an organic fertilizer turning machine to regularly turn it to ensure air circulation, accelerate fermentation speed, and control internal temperature to achieve the purpose of sterilization and deodorization.

3. Screening and crushing

After fermentation is complete, use a screening machine to remove non decomposable large particles or foreign objects. If necessary, use a grinder to grind the material to a finer state for subsequent granulation.

4. Adding auxiliary materials and mixing

Microbial agents, minerals, trace elements, etc. can be added at this stage to enhance fertilizer effectiveness, and the formula can be adjusted according to the needs of different crops.

5. Granulation

Using an organic fertilizer granulator to press the mixed raw materials into granules, common granulation methods include extrusion granulation, rotary disc granulation, extrusion crushing method, etc.

6. Drying and Cooling

The particles need to undergo a drying process to reduce the moisture content to an appropriate level to prevent decay or bacterial growth; After cooling to room temperature, prepare to proceed to the next step.

7. Packaging and Storage

Finally, weigh, package, and label the cooled organic fertilizer particles, store them in a cool and dry place, and wait for distribution.

Advanced technology application

Modern organic fertilizer production lines may also integrate automatic control systems, such as temperature and humidity monitoring and regulation, as well as clean production technologies, such as exhaust gas purification, wastewater treatment, etc., to ensure that the entire process is both efficient and environmentally friendly.

This entire process aims to maximize the utilization of nutrients in cow manure while eliminating potential pathogens and other harmful substances through scientific methods, ensuring that the produced organic fertilizer is both safe and effective.

Using straw as raw material to process fertilizers in organic fertilizer production lines not only effectively converts agricultural waste, but also has a series of significant advantages, making positive contributions to environmental, economic, and social sustainable development

Recycling resources: Straw is a rich source of organic matter, which is converted into fertilizer to achieve the recycling of agricultural waste, reduce environmental pollution caused by incineration or disposal, and reduce fertilizer dependence, promoting the healthy cycle of agricultural ecosystems.

Improving soil structure: Straw contains abundant cellulose, hemicellulose, and lignin, which are high-quality organic matter that can enhance soil water and fertilizer retention capacity, improve soil aggregate structure, and enhance soil biological activity. Long term use is beneficial for building a healthy soil ecosystem.

Supplementing nutrients: Straw also contains appropriate amounts of essential nutrients such as nitrogen, phosphorus, potassium, etc. Although the release is slow in the short term, long-term application can gradually supplement soil nutrients and promote crop growth.

Inhibition of weeds: The straw layer covering the ground can inhibit weed growth, reduce the use of herbicides, and further reduce the risk of chemical pollution in agricultural production.

Reducing greenhouse gas emissions: Compared to the large amount of carbon dioxide and harmful smoke generated by straw burning, converting it into fertilizer can greatly reduce the emission of air pollutants and have a positive effect on mitigating climate change.

Economic benefits: By collecting and selling organic fertilizers made from straw, farmers can not only save the cost of purchasing fertilizers, but also open up new income channels, achieving dual economic and environmental benefits.

Improving the quality of agricultural products: Crops produced using straw organic fertilizer often have higher quality, better taste, and are greener and healthier, in line with current consumers’ pursuit of food safety and nutritional value.

In short, the organic fertilizer production line utilizes straw to process fertilizers, which not only solves the problem of straw processing, but also promotes the green development of agriculture, demonstrating the huge potential of agricultural circular economy. Driven by both policy support and market demand, the utilization of straw fertilizers is becoming an important direction for the transformation of modern agriculture.

Sheep manure is rich in organic matter and nutrients, making it an ideal raw material for preparing organic fertilizers. Using an organic fertilizer compost machine for fermentation can effectively convert it into high-quality organic fertilizer. The following are the basic steps for fermenting sheep manure using an organic fertilizer turning machine:

preparation

Raw material collection: Collect enough sheep manure as the basic raw material. Depending on the actual situation, a small amount of other organic waste such as straw, sawdust, etc. can be mixed to adjust the carbon nitrogen ratio (C/N ratio). The recommended range is generally between 25:1 and 30:1.

Raw material pretreatment: If the humidity of sheep manure is too high, it needs to be preliminarily dehydrated through solid-liquid separation or natural drying, and the moisture content should be controlled between 40% and 60% to facilitate microbial activity.

fermentation process

Stacking: Stack the prepared raw materials into strips or piles, adjust the height, width, and length according to actual conditions, and maintain good ventilation.

Inoculation of fermentation bacteria: Spread specialized compost fermentation bacteria evenly in the raw materials to promote rapid and effective biodegradation process.

Start the compost turning machine: Use the organic fertilizer turning machine to regularly turn and mix materials, ensuring sufficient oxygen, balanced temperature, promoting microbial activity, and accelerating organic matter decomposition.

The frequency of flipping usually depends on temperature changes. When the central temperature rises to about 55 ℃ to 65 ℃, flipping is necessary to prevent beneficial bacteria from dying due to excessive temperature.

Monitoring and maintenance

During the fermentation process, it is necessary to monitor temperature, humidity, and odor, replenish water in a timely manner, and avoid being too dry or too wet.

Regularly check and record the fermentation progress until the material becomes soft, without obvious odor, and the color turns dark brown, indicating that the fermentation is basically completed.

Post processing

Post fermentation maintenance: After fermentation, let the compost stand for a period of time to further mature. This process is called “aging” or “secondary fermentation”, which helps to further decompose complex organic matter.

Crushing and sieving: Crushing mature compost to remove impurities, then sieving to obtain organic fertilizer with uniform texture.

Finished product application

The final product can be directly applied to farmland or gardens, or further processed, such as granulation and packaging, to increase the value of the product.

Using an organic fertilizer composting machine to ferment sheep manure not only effectively converts waste, but also produces environmentally friendly organic fertilizers, improves soil fertility, promotes crop growth, and is an effective way to achieve sustainable agricultural development. This method is particularly suitable for large-scale breeding farms and enterprises or individuals interested in developing circular agriculture.

The organic fertilizer production line converts cow manure into organic fertilizer, which not only effectively manages and recycles farm waste, but also creates a valuable byproduct for agricultural use or sale. Here is a basic production method and related investment budget overview:

summary

The total investment amount is influenced by multiple factors, such as production scale, automation level, geographical location, etc. Small organic fertilizer production lines may require tens of thousands of yuan to start, while large-scale industrial production lines may reach millions or even more. Therefore, before planning a project, it is necessary to conduct detailed market research, develop a reasonable business plan, and seek professional financial advice to ensure the feasibility of the project.

When selecting granulation equipment for NPK fertilizer production lines, multiple factors need to be considered comprehensively to determine the most suitable model. Here are a few key points that can help you make a reasonable choice:

Raw material characteristics: Understanding the characteristics of your raw materials is the top priority. The physical properties of raw materials (such as particle size, flowability, moisture content), chemical properties (such as corrosiveness, adhesiveness), and the presence of volatile or sensitive components can all affect the granulation process. For example, some raw materials may be more suitable for dry granulation, while others may require the addition of moisture or binders to form stable particles.

Particle requirements: Clearly define the characteristics such as size, shape, hardness, and dissolution rate of the target particles. Different crops and fertilization equipment may have specific requirements for fertilizer particles, such as some applications requiring small and uniform particles, while others prefer larger particles to reduce dust emissions.

Production capacity: Based on the expected output, select the equipment scale that can match your production needs. If large-scale production is planned, models with larger processing capacity should be selected; On the contrary, small-scale trial production is suitable for smaller experimental equipment.

Energy efficiency: Evaluate the energy consumption level and operating costs of different devices. Considering the cost-effectiveness of long-term operation, it is particularly important to choose energy-saving and efficient equipment.

Maintenance and operation difficulty: The ease of operation and maintenance of the equipment are also factors that cannot be ignored. Simple design and easy to clean structure can save a lot of time and labor costs.

Budget limitation: The investment cost and later operation and maintenance expenses of fertilizer granulator equipment should be within an acceptable range. Sometimes, high-performance equipment means higher initial investment, but it may also bring lower long-term total costs.

Supplier reputation and technical support: Choosing a manufacturer with a good market reputation and service system can provide more reliable technical support and after-sales service, which is very important for the normal operation and problem solving of equipment.

Compliance: Check whether the equipment complies with local environmental regulations and industry standards to avoid potential legal issues in the future.

Based on the above considerations and your specific production needs, you can consult professional equipment suppliers or industry experts for detailed scheme discussions, compare the advantages and disadvantages of different models, and select the most suitable NPK fertilizer production line granulation equipment for you.

The fermentation time of organic fertilizer compost machine is affected by various factors, mainly including the type of raw materials, initial conditions (such as temperature and humidity), microbial activity, and turnover frequency. The following is a general time frame for using an organic fertilizer compost turning machine to ferment fertilizers:

Raw material preparation stage: Firstly, organic raw materials (such as sheep manure, chicken manure, or other livestock manure) are mixed with other auxiliary materials (such as straw, rice straw, sawdust, etc.), and the appropriate carbon nitrogen ratio (C/N ratio) and moisture content are adjusted to create a favorable environment for microbial activity. The preparation time depends on the specific situation, mainly to ensure that the raw material is in a suitable state for fermentation.

Initial fermentation stage:

Temperature rise period: After the raw materials are stacked, as microorganisms become active, the temperature gradually rises, usually reaching a high temperature of 50-60 ℃ within 1-3 days. This is an important period for killing potential pathogens and seeds.

Continuous high temperature period: Once high temperature is reached, it is necessary to maintain this temperature for at least 5-7 days, sometimes up to two weeks, to ensure that all raw materials are fully decomposed and disinfected.

Flipping and cooling: Throughout the fermentation process, it is necessary to regularly use an organic fertilizer flipping machine to flip the compost, introduce new oxygen, adjust temperature and humidity, prevent local overheating, and help maintain optimal fermentation conditions. Generally, the pile is flipped every 3-5 days, and the specific interval can be flexibly adjusted according to the temperature monitoring results.

Maturity stage: When the temperature of compost begins to decrease, it indicates that most of the easily decomposable organic matter has been consumed and entered the maturity stage. At this point, the color of the compost becomes darker, the texture is looser, and there is no obvious odor. This usually occurs 2-4 weeks after fermentation begins, but full maturity may take several months to six months, depending on the composition of the raw materials and environmental conditions.

In general, the process of using an organic fertilizer turning machine to ferment fertilizers from raw material preparation to initial fermentation and final maturity takes approximately 4 weeks to several months. In order to achieve the most ideal fermentation effect, it is recommended to closely monitor the various parameters of compost, adjust strategies in a timely manner, and ensure a smooth transition at each stage. Note that different types of organic materials may have different fermentation characteristics, so adjustments should be made according to specific situations in practical operations.

The granulation equipment in the NPK fertilizer production line is the core part of the entire production process, used to process mixed powdered raw materials into granules for storage, transportation, and use. Here are some commonly used granulation equipment and their functions in NPK fertilizer production lines:

Disc granulator: This is a classic granulation equipment that works by utilizing the centrifugal force on a rotating disc to condense wet raw material powder into circular particles. It is suitable for granulation of most NPK fertilizers, with high yield and good forming rate.

Squeezing granulator: also known as a drum granulator, extrudes the mixed raw materials through a mold hole under high pressure to form cylindrical or tubular particles, which are then cut into specified sizes by a cutter. This granulation method is suitable for raw materials with good adhesion and is suitable for various industries such as fertilizers and feed.

Spray drying granulator: It is mainly used for direct granulation and drying of liquid or paste like raw materials. The solution is atomized into small droplets through spray devices, and then quickly dried and solidified into particles in hot air. This method is suitable for situations with high requirements for rapid drying, but the cost is relatively high.

Drum granulator: Similar to a disc granulator, but using a rolling cylinder instead of a disc, the raw material rolls and condenses into particles inside the cylinder due to heat. This design is suitable for large-scale continuous production.

Ring mold granulator: compresses the raw material through the pressure between the ring mold and the pressure roller, and extrudes it through the mold hole to form strip-shaped particles before cutting. It is suitable for processing hard and somewhat viscous materials, such as biomass fuels, fertilizers, etc.

Dry granulation machine: It can granulate without adding additional moisture and is suitable for materials that are easily hygroscopic. The material is compacted into blocks by mechanical force and then crushed into the desired particle shape.

The choice of granulation equipment mainly depends on the characteristics of the raw materials and factors such as expected particle shape, hardness, dissolution rate, etc. In actual production, it may be necessary to combine multiple devices to meet complex production needs. Proper matching of equipment specifications and maintenance are crucial for ensuring the efficient operation of NPK fertilizer production lines.
