Fermentation time of compost treatment in organic fertilizer production line

fertilizer granulator Jan 30, 2023

In the process of organic waste treatment in fertilizer production line, fermentation is needed for a certain period of time. Most organic fertilizer products are only composted and fermented for 15-20 days, which can only meet the harmless standard. So how long does it take to ferment to get high quality organic fertilizer?

The fermentation process of high quality organic fertilizer compost generally takes 45-60 days. This is because during the heating stage and high temperature stage of composting, harmful microorganisms such as plant pathogenic bacteria, insect eggs and weed seeds will be killed, but the main role of microorganisms in this process is metabolism and reproduction, and only a small amount of metabolites are produced, and these metabolites are unstable and not easy to be absorbed by plants.

Moreover, in order to make the fermentation of high quality, it is necessary to use the compost turning machine to process the materials. Moreover, it is more convenient to stir fermentation compost with organic fertilizer flipper and save manpower. When turning over and throwing, the materials stay on the pallet for a long time, disperse at high position, fully contact with air, and easy to drop moisture. A removable wear-resistant curved tooth blade is installed on the flip-flop support plate, which has strong crushing ability for materials when taking materials. Moreover, the materials in the trough are transported to a high position of 3m through the chain plate and then continuously dropped downward. The material movement track is long and fully contacted with the air in the process of overturning, which not only improves the oxygen supply time of materials, but also facilitates moisture volatilization, and promotes the rapid completion of aerobic fermentation. It is very suitable for occasions with large processing capacity, humid climate and continuous fermentation.

After the compost passes through the high temperature stage, the microorganisms will humusify the organic matter in the later cooling period, and in this process will produce a large number of metabolites beneficial to plant growth and absorption. So it needs post-corruption. The decomposed humus is used as a raw material to be mixed with other fertilizers, and then high-quality fertilizer products are made through rotary drum granulator.

The complete set of organic fertilizer equipment needs fermentation and turning machine, organic fertilizer grinder, drum screening machine, horizontal mixer, fertilizer granulator, rotary dryer, cooler, screening machine, coating machine, packaging machine, conveyor and other equipment.

Fermentation is the first step of pig manure organic fertilizer production. Composting fermentation is widely used in organic fertilizer production. So what are the complete steps of pig manure fermentation?
Treatment requirements of compost turning machine
1. Temperature requirements. The start-up temperature should be above 15 ℃ (it can be operated in four seasons and not affected by seasons. Fermentation should be conducted indoors or in Greenhouse in winter).

2. Materials are piled up. When doing heap, it should not be too small or too short. If it is too small, fermentation will be affected. The height is 1. The results showed that the fermentation effect was better when the length was more than 2-4 meters and 5-2 meters. Many organic fertilizer plants use fermentation tank for fermentation. The tipper can move flexibly on the track, with large treatment capacity and high efficiency.

3. Turn over the pile for ventilation. During the fermentation process, proper oxygen supply and composting should be paid attention to (overturn several times when the temperature rises to 75 ℃) and the temperature should be controlled at about 65 ℃. If the temperature is too high, the nutrients will be affected.

4. Fermentation is complete. Generally, the fermentation can be completed within a week, the material is dark brown, and the temperature begins to drop to room temperature, indicating that the fermentation is complete. If there are too many auxiliary materials such as sawdust, wood chips, and rice husks, the fermentation time should be prolonged until fully decomposed. After being decomposed, it is further processed by rotary drum granulator.

5. Material ratio. 1.5 tons of pig manure (about 2.5 tons of fresh manure) plus 1 kg of fertilizer starter, the starter must be mixed with rice bran (or bran, corn flour and other substitutes) in a ratio of 1:5, and then evenly sprinkled Put it into the pig manure pile and mix evenly.

In recent years, in order to further protect the ecological environment and reduce air pollution, the state advocates the use of chicken manure, cow manure, pig manure and other livestock manure to make organic fertilizer instead of chemical fertilizer. In addition, the state will have corresponding preferential policies and subsidies for the purchase of organic fertilizer or the purchase of organic fertilizer production equipment. With the policy support and subsidy amount, many large farm owners and farmers’ friends have purchased organic fertilizer in succession, greatly increasing the domestic market demand for organic fertilizer, thus increasing the purchase rate and demand for organic fertilizer equipment. The establishment of organic fertilizer equipment and fertilizer processing plant has paid off handsomely. Especially in the countryside, there is a huge shortage of organic fertilizer equipment. To set up an organic fertilizer processing plant in the countryside can collect livestock manure from farmers for processing. How much is it to set up a large organic fertilizer production line with an annual output of 10-20 million tons?

A complete set of large-scale livestock and poultry organic fertilizer production lines with an annual output of 10-20 million tons include: forklift feeder, trough stacker, vertical crusher, drum screening machine, dynamic batching machine, granulator, round throwing machine, dryer, cooler, coating machine, automatic quantitative packaging scale.

First, use the dehydrator to control the water content of poultry and livestock excrement to less than 85%, and then add straw powder, rice bran, corn flour and other auxiliary materials. After fully mixing with the mixer, use the forklift to shovel it into the fermentation tank, and use the organic fertilizer tipper to fully ferment and ripen; The conveyor belt between the equipment is used to transport the particles to the pulverizer for crushing, and then to the organic fertilizer granulator for granulation. The produced particles have high moisture content, and then enter the cooler after being dried by the dryer to cool the particles and improve the particle strength. Then it is sent to the drum screening machine to screen out unqualified particles for secondary granulation, and then it is packaged with a packaging machine to produce finished products.

Maintenance method of common equipment in NPK fertilizer production line

fertilizer granulator Jan 30, 2023

1. Dust is one of the factors that cause equipment wear on the NPK production line. Fertilizer production equipment generates dust during operation. If it is not cleaned and maintained in time, dust will enter various joints of the equipment. As time goes by, the friction at the joints of the equipment will increase, which will affect the performance of the equipment. Therefore, apart from using fertilizer equipment, we must conduct a comprehensive inspection and maintenance of the equipment.

2. During the operation of the NPK production line, staff also need to pay attention to the degree of lubrication of the equipment joints. The long-term use of equipment is a severe test of equipment lubrication. Once the jam occurs, the friction of the equipment will increase. Only with a high degree of lubrication can the operation of the equipment be supported by good power and be cleaned regularly.

3. We need to pay special attention to the motor friction of the fertilizer granulator and related equipment. Motor wear will affect the use of organic fertilizer equipment. The staff should pay attention to checking the operation of the motor at all times. Especially before the load is running, the circuit of the motor should be checked, and if it is damaged, it needs to be updated immediately.

During the operation of NPK production line, the fertilizer mixer and other equipment should be checked frequently. In case of abnormal noise, impact, vibration and sharp temperature rise, it should be checked immediately and the operation can be continued after troubleshooting.

1. Before commissioning the mixer, add gasoline or kerosene, clean the parts in the tank and oil pool after running, and then add gear oil and put it into operation.

2. Before commissioning, manually climb the belt pulley to make the main shaft idle for several weeks, and start it only after confirming that there are no obstacles and abnormal phenomena.

3. When starting the main engine, it is necessary to wait for the motor to reach the rated speed, and then make the clutch combine slowly. Do not use too much force to damage the parts and reduce the service life of the machine.

The major repair and maintenance of fertilizer mixer is carried out once a year, and the medium maintenance is carried out once a month. All mechanical sliding parts must be added with grease to ensure the flexibility of equipment operation. The normal treatment of the fertilizer mixer can make the raw material conform to the processing of the fertilizer granulator.

Aerobic compost fermentation is the foundation of processing fertilizer in organic fertilizer production line

fertilizer granulator Jan 16, 2023

Aerobic composting technology is an important technical means for the disposal of organic waste, especially suitable for the realization of fertilizer and substrate of agricultural solid waste. For industrialized processing of organic fertilizer, compost turning machine is usually used to ensure the smooth progress of aerobic fermentation.

Aerobic composting is the absorption, oxidation, and decomposition of waste by aerobic bacteria under aerobic conditions. Through their own life activities, microorganisms oxidize part of the absorbed organic matter into simple inorganic matter, and at the same time release the energy required for the growth of microorganisms, while the other part of the organic matter is synthesized into new cytoplasm, so that the microorganisms continue to grow and reproduce. The process of producing more organisms. Under artificial control, under certain moisture, C/N ratio and ventilation conditions, the waste organic matter is converted into fertilizer through the fermentation of microorganisms. This process is called aerobic composting.

The compost is granulated with fertilizer granulator. The raw materials mixed in organic matter are different, which can meet the needs of different regions and crops. After compost is processed into commercial organic fertilizer, the effect is better and the value is higher. In order to renew soil organic matter, organic fertilizer must be added. Obviously, it is very important to apply organic fertilizer to improve soil fertility.

Aerobic composting technology is the most effective industrial means to dispose agricultural solid waste, ferment it into organic fertilizer and realize resource utilization. NPK production line can not replace the processing of organic fertilizer. Countries all over the world attach great importance to the application of advanced engineering technology to improve the industrialization level of aerobic composting technology, so that the composting technology is developed towards mechanization, environmental protection, high efficiency and integration.

How to build a production line of small livestock manure processing organic fertilizer equipment

fertilizer granulator Jan 16, 2023

Organic environmental protection is the main body of the current society. About organic products, we are familiar with organic vegetables and organic fruits. These organic products are produced with the help of organic fertilizers. With the implementation of the new environmental protection law, the environmental protection threshold has been continuously raised. In order to deal with the farming manure, the farms have started to build their own or combine with fertilizer enterprises to use organic fertilizer production line equipment to process the manure.

Process flow of organic fertilizer equipment: the recovered livestock and poultry manure directly enters the fermentation zone. The odor of livestock and poultry excrement can be eliminated through primary fermentation and secondary aging. At this stage, fermentation can be added to decompose the crude fiber, so that the particle size after crushing meets the particle size requirements of granulation production. Crush the fermentation materials that have completed the secondary aging and stacking process and enter the mixing and mixing system. Before mixing and mixing, add N, P, K and other trace elements into the mixing and mixing system according to the formula and start mixing. The mixed materials are transported to the granulation system, and the granulation enters the cooling system after passing through the dryer. The materials are screened after reaching the normal temperature. The particles that meet the requirements enter the coating machine to wrap the film and start packaging. The particles that do not meet the requirements are crushed by the pulverizer and then returned to the granulation system to continue granulation.

The compost turner is a great investment to go along with your fertilizer plant. You can quickly make compost and you will be ready to sell it so much faster. The compost mixer turner makes it much easier to finish the compost. It saves you money and ensures you can start producing your fertilizer so much faster.

Process flow of sheep manure organic fertilizer production line

The sheep dung is mainly produced by tank aerobic fermentation, which is a common method to treat sheep dung at present. It is also suitable for the commercial production of sheep dung organic fertilizer, and is conducive to standardized production. Sheep dung urine is rich in nutrients, which can be easily decomposed into effective nutrients that can be absorbed and used by crops, as well as slow nutrients that are not easy to decompose. It is a good fertilizer combining fast and slow fertilizer efficiency. The content of organic matter in sheep manure is 24% – 27%, nitrogen content is 0.7% – 0.8%, phosphorus content is 0.45% – 0.6%, potassium content is 0.3% – 0.6%, organic matter content in sheep urine is 5%, nitrogen content is 1.3% – 1.4%, phosphorus content is low, potassium content is very rich, up to 2.1% – 2.3%.

Mix sheep dung with a proper amount of straw powder. The amount of mixing depends on the water content of sheep dung. Generally, 45% of the water content is required for fermentation. That is to say, knead it into a ball by hand, see water in the fingers, but do not drip, and release it to dissolve. Then add corn flour and bacteria. The role of corn flour is to increase sugar content for bacteria fermentation, so that multi-dimensional complex enzyme bacteria take advantage.
Add the prepared mixture into the mixer for mixing. The mixing must be uniform, transparent and free of raw blocks.
The mixed ingredients are stacked into strips with a width of 1.5 meters to 2 meters and a height of 0.8 meters to 1 meter, which are flipped once every 2 days with a tipping machine.
The compost is heated for 2 days, odorless for 4 days, loose for 7 days, fragrant for 9 days, and composted for 10 days (that is, the temperature on the second day of composting can reach 60℃- 80 ℃, killing diseases and insect pests such as Escherichia coli and insect eggs; the stink of sheep dung is eliminated on the fourth day; the compost becomes loose and dry on the seventh day, full of white hypha; a kind of liquor starter flavor is produced on the ninth day; the compost is fermented and matured on the tenth day).
After a little drying, it can be crushed by a semi-wet material crusher, granulated by an organic fertilizer granulator, dried and dehydrated by a dryer, and then screened by a screening machine. The finished organic fertilizer is ready for packaging and storage.

Organic fertilizer production line mainly crushes the previously fermented organic fertilizer raw materials, then sieved, and then measures the raw materials and other compatible components of the adhesive. After further drying to produce powder organic fertilizers), the materials that are fully mixed are evenly delivered to the granulator to make granules through the belt conveyor.

Treatment methods and advantages of manure organic fertilizer production line

fertilizer granulator Jan 16, 2023

Organic fertilizer fermentation equipment is widely used in organic fertilizer production, which can improve production efficiency and produce high-quality organic fertilizer. Before the production of organic fertilizer, manure should be treated to achieve the best effect.

Mode of manure treatment of organic fertilizer

1. Dry chicken manure mode

Its technological process is that chicken manure is directly through high temperature, heating, sterilization and drying, and finally dried chicken manure with water content of about 13% is sold directly as a product. Many manufacturers adopt this mode of production,

The advantages of this mode are: 1. Large production and fast speed; 2. Stable product quality and low moisture content.

But at the same time, there are also shortcomings: 1. The tail gas produced in the production process pollutes the environment. 2. The energy consumption in the production process is high, and the energy consumption per ton is about 200 yuan. 3. The quality of the product is not reliable because of its dry surface, bad smell and secondary fermentation after soaking in water. 4. The equipment investment is large and the utilization rate is not high. 5. The organic matter content in chicken manure is not up to the standard.

2. Direct drying mode

Its main technological process is to spread chicken manure directly in the air, after drying, crushing and packaging directly as a product for sale.

The advantages of this mode are: low cost and simple operation.

But it also has disadvantages: 1. It occupies a large area and pollutes the environment. 2. There is also a problem of seasonality and seasonality in air drying, so the fertilizer production line can not be produced continuously through factory. 3. It is difficult to guarantee the quality of the product due to its large volume, low nutrient content and secondary fermentation.

3. Compost fermentation mode

Manure compost fermentation is the main treatment method of organic fertilizer production line. The requirements of compost turning machine are not high. When tank fermentation is selected, the materials suitable for moisture adjustment are laid in the fermentation tank of solar composting workshop. After high temperature fermentation, the harmful substances in raw materials are killed to ensure the safety of fertilizer. At the same time, the decomposed compost is further made into high-quality fertilizer by the organic fertilizer granulator machine in the fertilizer production line.
