The production principle of organic fertilizer is mainly to use organic fertilizer equipment to quickly ferment and mature into organic fertilizer. It is necessary to add biological fermentation equipment and use chicken manure fermentation equipment for aerobic fermentation. Biofertilizer fermentation agents can ferment the excrement of animals such as pigs, cows, sheep, chickens, ducks, quails, etc. to produce organic fertilizer, as well as ferment and mature various straw, fallen leaves, withered grass, etc. to produce bio organic fertilizer, making it very convenient to obtain materials.

Firstly, we need to carry out fermentation. The main purpose of fermentation is to allow the cow manure to undergo sufficient high-temperature decomposition, which will eliminate the bacteria and weed seeds in the manure. The addition of beneficial fermentation bacteria will breed a large number of beneficial microorganisms, improve the various beneficial trace elements of organic fertilizer. During fermentation, we need to adjust the carbon nitrogen ratio to around 25:1, water content to around 55%, and then add fermentation agents, Start a fermentation cycle of about 15-20 days, during which regular stirring and temperature control are required to better contact the raw materials with oxygen, in order to accelerate fermentation and ripening. If it is a small amount of operation, manual labor or small agricultural forklifts can be used for flipping and mixing. If the amount is large, a professional cow manure organic fertilizer flipping and throwing machine needs to be used. After the fermentation cycle is completed, our cow manure organic fertilizer will be fermented. However, the organic fertilizer fermented in this way is relatively crude and only suitable for self use or short distance sales, and the profit margin is also very low. If it can be made into commercial organic fertilizer, the profit per ton should also be at least 200-300 or more. To produce commercialized organic fertilizer, further processing is required. Powdered organic fertilizer needs to be crushed into powder using a cow manure crusher, and granular organic fertilizer needs to be made into cow manure granular fertilizer using an organic fertilizer granulator.

The equipment we can choose includes: organic fertilizer flipping equipment, organic fertilizer crusher, horizontal mixer, organic fertilizer granulator, dryer, cooler, screening machine, packaging machine, etc. Due to the different quality of equipment produced by different organic fertilizer equipment manufacturers, the service life of the sheep manure organic fertilizer processing production line we have built is different, which seriously affects the investment of the sheep manure organic fertilizer processing production line.

 In today’s society, with the increasing demand of consumers for intelligent production of organic fertilizer granulator, the multifunctional organic fertilizer equipment will receive more attention and love from customers.
Facing the huge market population, the demand for organic fertilizer granulator will naturally increase. In order to better serve customers and consumers, the organic fertilizer granulator manufacturers only think about the direction of intelligence and automation, in order to better improve the production technology of organic fertilizer production equipment. Therefore, in order to make the organic fertilizer equipment better serve customers, the enterprise only needs to carry out technological innovation on the equipment as soon as possible, so that the development of the equipment is closer to the production, so that the organic fertilizer machine will develop more healthily. Only with the continuous upgrading and rapid growth of organic fertilizer machinery, can we better promote the development of enterprise economy.

So far, almost 80% of the organic fertilizer machines have completed the progress of agricultural circular development. As we know, biogas is recyclable. This development model has played an environmental protection role, effectively prevent pollution, improve the utilization rate of waste, can be said to turn waste into treasure, now the organic fertilizer granulator has also realized the function of green environmental protection.
Organic fertilizer machine is actually to convert animal manure fertilizer into organic fertilizer, in which some crop straw can be added into animal manure. Now with the continuous improvement of technology, the technical level of organic fertilizer granulator manufacturers and organic fertilizer equipment has also reached a new level. Now, the power of organic fertilizer equipment manufacturers is growing. 

The fertilizers processed on the pig manure organic fertilizer production line mainly have the following advantages:

1. Pig manure organic fertilizer does not contain any chemical components.

The main raw material for pig manure organic fertilizer is organic matter, which increases the content of organic matter in the soil.

3. Pig manure organic fertilizer can also produce a large number of microorganisms in the soil, especially many beneficial microorganisms such as nitrogen fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, nitrifying bacteria, etc.

Process flow of pig manure organic fertilizer production line

Pre fermentation inspection: If the moisture content in the raw materials is too high, a dry wet separator can be used to reduce the moisture, or straw can be added to control the moisture. The moisture content can be controlled at around 55% before fermentation can begin. Check for the highest moisture content

The simple way is to grab it with your hands. If the water flows through your fingers, it indicates that the moisture content is too high. If it is squeezed into a ball, it indicates that the moisture content is low. It is best to hold it with your hands without spilling.

Fermentation process: Organic fertilizer bacterial agents can be added according to the product, and if there are no requirements, they may not be added. If you want to accelerate the fermentation speed of raw materials, you can add organic fertilizer fermentation agents. During the fermentation process, pay attention to controlling the fermentation temperature at all times. When it reaches around 70 degrees, use an organic fertilizer tipping machine to flip it until the fermentation is completed.

Organic fertilizer crushing: After the pig manure organic fertilizer raw material is fermented and matured, it is crushed using an organic fertilizer crusher. If it is produced as powdered organic fertilizer, it can be directly packaged and stored. If producing granular organic fertilizer, it is necessary to use a dedicated organic fertilizer granulator for granulation, and then use organic fertilizer screening machines, organic fertilizer drying machines, and other equipment to better process and improve the quality of pig manure organic fertilizer products.

Regarding the impact of environmental protection policies on the organic fertilizer production line industry, as the main raw materials are non renewable resources such as land, the policy orientation has begun to advocate environmental protection and energy conservation policies. The country has to make relevant adjustments in the development direction of related industries. The development speed of organic fertilizer production lines is rapid, and market demand is constantly expanding, thanks to the support and guidance of relevant national policies. Further understanding of the current organic fertilizer industry has begun to touch on the core part of industry policies. Production enterprises should actively face market challenges, focus on investment in high-tech, and further adjust their products according to market demand.

The pellet produced by disc fertilizer granulator machine is suitable for machine sowing, and the output is relatively high. The kneaded material is rolled into a round ball with no return material, high efficiency and good strength. Beautiful appearance, reasonable structure, safe and reliable, easy to operate.
Disc fertilizer granulator machine has a strong ability to prevent overload, even in the case of full load, there is no need to set up a separate feeding device.

The characteristics of disc bio organic fertilizer production technology are as follows:
1. It can directly produce spherical particles in one step, no size and no material return, and the rate of ball forming is more than 95%. Therefore, the production cost is low and it is suitable for machine seeding.
When the moisture content of raw material is about 40%, the drying and post-treatment are easy and the drying cost is low. Because it can be dried at low temperature or in the air, it will not affect the number of bacteria in the biological fertilizer.
3. Wet granulation has the advantages of low wear and low cost.
4. It has wide adaptability to all kinds of materials used in organic fertilizer granulation. 

There are two main types of organic fertilizers processed by organic fertilizer production equipment: powdered fertilizers and granular fertilizers. Granular fertilizers are more commonly used in daily processing. The main purpose of using organic fertilizer production equipment to produce granular organic fertilizers is to facilitate bagging and transportation to prevent secondary fermentation of organic fertilizers. In addition, in terms of sales level, granular organic fertilizers are better sold.

According to primary and secondary
(1) Main raw materials. The main raw material of organic fertilizer production process accounts for 30% – 80% of the whole material, which is composed of one or several raw materials. The main materials commonly used are animal manure, straw powder, mushroom residue and so on.
(2) Accessories. It is mainly used to adjust moisture, carbon nitrogen ratio, pH value and permeability of some raw materials, composed of one or several raw materials. Usually, this kind of raw material accounts for less than 40% of the whole material, and the proportion of single material is less than 20%. The commonly used auxiliary materials are wheat bran, soybean meal, peat, plant ash, quicklime, etc.
Classification by raw material properties
According to the properties of raw materials, it can be divided into carbon containing raw materials, nitrogen containing raw materials and conditioner raw materials.
(1) Carbonaceous materials. It refers to the raw materials with high organic carbon content, which are usually used as main composting materials, such as straw, rice husk, mushroom residue, etc. In addition to straw composting, most of the carbonaceous materials are used as auxiliary materials to adjust water content, carbon nitrogen ratio, bulk density and enhance the permeability of materials.
(2) Nitrogen containing raw materials. Generally refers to the raw materials with carbon nitrogen ratio below 30:1, such as livestock manure. There are also some high nitrogen raw materials used as auxiliary materials to adjust the carbon nitrogen ratio, such as soybean meal, fish meal, etc.
(3) Conditioner raw materials. It mainly refers to raw materials used to adjust pH value, such as quicklime to adjust acidity and gypsum to adjust alkalinity. Sometimes the raw materials used to adjust the C / N ratio are summarized as regulators, such as superphosphate, phosphate rock powder, etc. 

Small organic fertilizer equipment worth around 11000 yuan is highly welcomed by ordinary farmers. There are many raw materials for organic fertilizer, such as livestock and poultry manure, agricultural waste, plant ash, mushroom residue, etc. The majority of livestock and poultry manure is treated, many of which are owned by farmers. Small organic fertilizer production lines can meet this requirement, not only solving the problem of emission reduction and disposal of livestock and poultry manure, but also making money from livestock and poultry manure, bringing significant profits.

Organic fertilizer production lines are generally divided into two categories: powder organic fertilizer production lines and granular organic fertilizer production lines, taking powder organic fertilizer production lines as an example. The equipment required includes fermentation and tipping equipment, pulverizer equipment, and organic fertilizer screening equipment. The price is around tens of thousands of yuan, which needs to be determined based on annual production and equipment specifications.

1. Determine the scale of the small-scale organic fertilizer equipment production line, such as how many tons per year or how many tons per hour, before determining the price.

2. Determine the shape of particles in the production line of small organic fertilizer equipment, that is, choose what type of granulator: powder, column, flat ball, or standard park. Commonly used organic fertilizer granulator equipment includes: disc granulator, drum granulator, wet granulator, drum extrusion granulator, flat mold granulator, and stirring tooth granulator. The selection of granulators should be determined based on the local organic fertilizer sales market. If the shape requirements of the particles are different, then the processing process of organic fertilizer equipment is also different, and the price of organic fertilizer equipment is also different.

3. Determine the configuration of small organic fertilizer equipment production lines: The equipment configuration of organic fertilizer production lines varies, with varying prices and labor intensity. If the output is stable and high, the general configuration is relatively high. In addition to the basic equipment, automatic batching equipment, automatic packaging equipment, automatic quantitative feeding equipment, cyclone dust collector, solid-liquid separation equipment, etc. should also be added.

4. Determine the type of organic fertilizer production. Compound organic fertilizer equipment or organic fertilizer equipment, with the same yield, generally considers high moisture content, beneficial bacteria not resistant to high temperature, and the model is larger than the compound fertilizer model. There are four types of organic fertilizers: pure organic fertilizer, organic-inorganic composite fertilizer, bio organic fertilizer, and composite microbial fertilizer, with slightly different configurations of organic fertilizers.

5. Selection of organic fertilizer fermentation tipping machine: Common organic fertilizer fermentation methods include strip fermentation, tank fermentation, and the use of fermentation tanks. The fermentation methods and equipment for organic fertilizer fermentation are also different. In general, the tank fermentation tipping machine is more suitable for the principle of aerobic fermentation (advantages of tank fermentation: it is more in line with the principle of aerobic fermentation, less prone to the formation of anaerobic bacteria, complete fermentation, and fast fermentation speed).

6. Determine the environmental assessment to be achieved: select ordinary dust removal equipment in areas with low environmental assessment requirements, and invest less in organic fertilizer equipment; Areas with high environmental protection requirements require the use of high-performance dust removal equipment, which has good performance and can fully meet national environmental standards. Therefore, the investment will also be higher.

The non drying extrusion granulation process of double roller granulator has a wide range of applications in powder processing. Its characteristic is that it can process particles directly without humidifying or heating materials. It can be used for the processing of organic and inorganic fertilizer granules and feed granules.

No waste water or waste gas will be discharged in the production process by using the non drying extrusion granulation process, and the environment will not be polluted. Extrusion double roller granulation process is short, easy to operate, easy to realize production automation control and improve production efficiency. There are no special requirements for the properties and particle size distribution of raw materials, so the sources of raw materials are wide.

Five stages of the production process of organic fertilizer by double roller granulation
1. Add the qualified raw materials into the fertilizer mixer machine according to the proportion requirements and mix them evenly.
2. It is transported to the disc feeder, and the metallic substances in the material are removed during the conveying process.
3. The material in the disc feeder evenly enters into the double roller granulator, and the material is forced to pass between the two pressure rollers to be squeezed into thin plates. The thin plates are crushed into fragments by the coarse crusher under the pressure roller and then screened. The materials on the screen continue to be broken and sieved.
4. The semi-finished products are transported to the finished product screening machine. The screened fine particles are directly returned to the disc feeder. The large particles are crushed by the pulverizer and then returned to the disc feeder.
5. After screening, the qualified products are transported to the automatic packaging scale for weighing, packaging and warehousing. 

With the increasing attention of governments at all levels and the recognition of organic fertilizer by farmers, the production and market of organic fertilizer have entered a period of rapid development. In the process of organic fertilizer production by organic fertilizer machine, feed production equipment or general compound fertilizer production equipment is commonly used, but it is often not suitable for selection due to poor pertinence.

1: The results showed that the crawler type compost windrow turner should be used in the strip stack fermentation. This type of composting method has the advantages of flexibility, simplicity, large treatment capacity and good air permeability. When processing the same volume of organic materials, the area occupied by strip stack fermentation is 2-3 times of that of trough fermentation.

2: Trough fermentation: trough fermentation is generally a partition wall built on the cement floor, and the top of the partition wall is paved with guide rails. The compost windrow turner walks on the guide rail and is equipped with a rail changing mechanism. The tipper can move from one trough to another. Whether it is a self-propelled compost windrow turner or a trough tipper with multiple troughs or one trough with one machine, the operation of the tipper will be more flexible if it has the function of breaking and stirring during the turning process.

3: The main equipment of trough fermentation is chain plate compost windrow turner; the chain plate compost windrow turner can be equipped with bacterial liquid spraying device, which can well meet the process requirements and spray mixed bacterial liquid according to the working characteristics of the compost windrow turner, so as to reduce the mixing process in the early stage.
