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?

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.

The complete set of granular fertilizer production line equipment includes: trough fermentation equipment – forklift silo – pulverizer – mixing mixer – disc granulator – dryer – cooler – screening machine – coating machine – packaging machine, and the equipment is connected by conveyor.

Fecal dehydrator, fermentation tipper, semi-wet material crusher, horizontal mixer, granulator, dryer, cooler, drum screening machine, coating machine, packaging equipment, belt conveyor, etc.

Introduction to the process of organic fertilizer production line with an annual output of 10000 tons

1. In the early stage, the organic fertilizer fermentation equipment uses 7.5kw-11KW motor power of a 3m or 4m fermentation tipping machine, which can be used in multiple tanks.
2. The organic fertilizer crushing equipment is a large semi-wet material crusher with a motor power of 21kw and an output of 3-5 tons per hour.

9. The automatic packaging machine realizes automatic weighing and sewing of 3-6 bags per minute.

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.

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%.

1. 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.
2. Add the prepared mixture into the mixer for mixing. The mixing must be uniform, transparent and free of raw blocks.
3. 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.
4. 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).
5. 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.

NPK production line can process different chemical fertilizers to obtain agricultural special crop compound fertilizer. NPK fertilizer granulation process can be generally divided into: raw material batching, NPK fertilizer mixing, compound fertilizer granulation, particle drying, particle cooling, particle grading, finished product coating and final product packaging.

Processing technology of NPK production line

Bio fertilizer granulator is used for granulation of various organic substances after fermentation, breaking through the traditional organic granulation process. Raw materials do not need to be dried and crushed before granulation. Spherical particles can be directly batched and processed, saving a lot of energy. The traditional fertilization and garbage fertilization methods not only cause some harm to the environment, but also do not give full play to their role. With the application of more and more organic fertilizer, compound fertilizer, microbial fertilizer and chemical fertilizer, granulating equipment such as biological fertilizer granulator has entered people’s life and production.

The double roll extruding granulator has the following advantages: 1. It operates circularly to realize continuous production and high output of finished products; 2. The material is forced to be compressed and shaped by mechanical pressure without any additives, so as to ensure the purity of the product. 3. The particle strength can be adjusted, and the finished product strength can be controlled by adjusting the pressure of the roller; 4. The extruding granulator is applicable to various raw materials, and the particle strength can be adjusted freely according to different materials. 5. Compact structure, convenient maintenance, simple operation, short process flow, low energy consumption, high efficiency and low failure rate.

The Double Roller Extrusion Granulator for Compound Fertilizer Making is a necessary tool for NPK fertilizer’s efficient and successful production. This strong machine can produce compound fertilizer granules with uniform size and shape and high accuracy and consistency. The process of making granules using this granulator is simple and straightforward, allowing for larger batches to be produced fast and economically. This granulator is designed to handle a wide range of raw materials, enabling for the production of a wide range of compound fertilizer types. It can also process solid and liquid raw materials, making it incredibly versatile.

Organic fertilizer can improve the utilization rate of fertilizer in the soil. The main raw material of organic fertilizer is animal manure. They include: pig, cow, chicken, sheep, etc. There are many advantages in using sheep manure to produce organic fertilizer.

Technology of sheep manure organic fertilizer production line

The organic fertilizer composting machine is mainly applicable to farms of various sizes, and its application value is worthy of affirmation. Generally, farmers are very familiar with this kind of animal husbandry machinery. However, because of this situation, many users will use it according to their own operating methods, so there will be some improper operations, resulting in many mechanical failures, inflexibility and inconvenience to use.

1. The main operation method of theorganic fertilizer compostercan be operated by adults. Workers should pay close attention to it and not chat with other workers. This method of operation is wrong.
2. The main function of theorganic fertilizer composteris to ferment animal manure on the farm and transform it into green and environment-friendly organic fertilizer through a series of operation methods. As this product is mainly used in farms, we must ensure the safety of cattle and other farmed animals during the use. Generally speaking, when using, try to avoid conflicts with the feeding time of animals, separate them from these times, or drive animals to other places for captive breeding, so as to avoid mechanical noise affecting cattle and causing adverse consequences.
3. In the process of using the organic fertilizer composter, some animal feces and other feces may stick to the drum. At this time, we will stop the machine, clean up the feces stuck on the drum, and then continue to work.
