In today’s society, with the strict investigation of environmental protection and the rapid development of organic agriculture, the use of organic waste in organic fertilizer through biological fermentation has developed rapidly in China. Therefore, the equipment for biological organic fertilizer has been highly praised, and the organic fertilizer production line has achieved the harmless and resourceful treatment of organic waste. However, the organic fertilizer produced by biological fermentation is mostly coarse powder or irregular small pieces. It is particularly inconvenient to use and is very detrimental to large-scale transmission. After years of experience in designing and producing compound fertilizer processing equipment, manure organic fertilizer granulators, bio organic fertilizer granulators, and organic fertilizer granulators have emerged. These devices are suitable for granulation of various organic substances after fermentation, breaking through traditional granulation processes. Before granulation, there is no need to dry and crush raw materials. Spherical, cylindrical and other particles can be directly processed, making the use of organic fertilizers more convenient and promoting the range of use of environmentally friendly organic fertilizers.

The roller extrusion granulator belongs to the extrusion sliding model, and its working principle is: the belt and pulley are driven by an electric motor, transmitted to the driving shaft through a reducer, and synchronized with the passive shaft through a split gear, working in opposite directions. The material is added from the feeding hopper, extruded into shape by rollers, demolded and pelletized, and transported through a pair of chains to the crushing screen studio. The finished particles (balls) are screened and separated, and then returned to be mixed with new materials before pelletizing. With the continuous rotation of the motor and the continuous entry of materials, mass production can be achieved.

Organic fertilizer stirring tooth granulator: It is a molding machine that can manufacture materials into specific shapes. The wet stirring tooth granulator utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, and compact fine powder materials in the machine, thus achieving the purpose of granulation. This granulation method results in a higher ball forming rate and more beautiful particles, while also saving energy and being efficient and energy-saving.

Organic fertilizer flat film granulator: This machine can produce granular feed, organic fertilizer, cylindrical particles, and can also connect polishing equipment to make cylindrical particles roll into balls in one go, without returning particles, with high ball forming rate and good strength. It is an ideal equipment for organic fertilizer granulation.

The successful development of manure fermentation organic fertilizer equipment has effectively solved the problem of manure resource utilization. It is achieved by mixing cow manure or sludge with organic waste such as straw and corn cob in a certain proportion to achieve a suitable moisture content, and then conducting high-temperature fermentation and ripening. During the fermentation process, continuous oxygen filling and stirring are carried out to naturally heat up the mixed materials, ferment and ripen, kill a large number of bacteria and pathogens, and do not produce odor. The fermentation process is completely closed, It will not cause secondary pollution, and the output will be in a crushed form, which can be directly used for agricultural topdressing. It can also be used as an organic fertilizer raw material for deep processing to become agricultural organic fertilizer with nitrogen, phosphorus, and potassium content meeting standards. On this basis, wheat straw and corn cob truly achieve pollution-free resource utilization.

The organic fertilizer production line for processing organic fertilizers is jointly completed by a series of equipment, including chain plate stacker tank fermentation equipment. Chain stacker is an efficient organic fertilizer production line, and the equipment characteristics of chain stacker are as follows:

1. Deep pool continuous aerobic fermentation, with a short fermentation cycle (7-8 days) and complete fermentation maturity;

2. The forced oxygen supply system adopts a high-pressure Roots blower for air burst, with strong penetration ability of oxygen supply in the material layer, which can ensure that oxygen is evenly supplied to the material from the bottom of the pool without dead corners, and the fermentation is even;

3. The lifting chain adopts a specially designed and dedicated chain, with a long service life, safety and reliability; The lifting mechanism is driven by hydraulic pressure, ensuring smooth operation;

4. Set up an intelligent automatic control system to achieve intelligent control of the working process of the front and rear, left and right, up and down running mechanisms of the tipping machine during the tipping process,;

5. Small footprint, low energy consumption, large production capacity, fast stacking speed, wide adaptability of raw materials, and stable product quality.

6. The use of pool type continuous fermentation technology provides the temperature and oxygen required for fermentation on the basis of beneficial microorganisms, allowing fermentation to be carried out under controllable conditions in the pool, reducing the impact of adverse factors in nature, ensuring year-round production, and adapting it to the characteristics of industries such as aquaculture.

The design of the organic fertilizer chain plate stacker is reasonable, the motor consumes less electricity, and the transmission adopts a hard faced gear reducer, which has low noise and high efficiency. Key parts such as the chain are made of imported components, which are durable. The lifting and lowering use an oil pressure device, and the stacker depth can reach 1.8-2.0 meters. The vertical lifting height of the material can reach 2 meters, and it stays in the air for a long time without aeration. Other forms of stacker can do what three fermentation tanks can do, using a chain plate stacker, One is enough

Ammonium bicarbonate and diammonium phosphate are commonly used fertilizers in agriculture, which are processed by fertilizer production line. So what are the key points of fertilization technology in use?

Ammonium bicarbonate

Ammonium bicarbonate, with about 17% nitrogen content, is the lowest nitrogen content in solid nitrogen fertilizer. Ammonium bicarbonate generally has a moisture content of 5% – 6%, which is easy to deliquescence and caking. When the temperature is lower than 20 ℃, the ammonium bicarbonate will decompose into ammonia and carbon dioxide when the temperature is slightly higher or the moisture content in the product exceeds a certain standard, which will cause the loss of nitrogen fertilizer efficiency. It is a physiological neutral available nitrogen fertilizer, which is suitable for all kinds of crops and soils, and can be used as base fertilizer and topdressing fertilizer. Therefore, it is also used as raw materials and other nutrients, and processed into other special fertilizer by disc granulator after batching.

It can be used as basal fertilizer in furrow. If it can be combined with deep application of cultivated land, its effect will be better. However, it should be noted that the depth of application should be greater than 6cm (sandy soil can be deeper), and the soil should be covered immediately after application, only in this way can the loss of nitrogen be reduced. When ammonium bicarbonate is used as topdressing, the dry land can be combined with intertillage. The depth of application should be less than 2 inches, and the soil should be covered immediately, and the water should be timely watered. The paddy field should keep a shallow water layer of about 1 inch, but not too shallow, otherwise it is easy to damage the root. After application, plough and rake in time to promote the fertilizer to be well absorbed by the soil.

When ammonium bicarbonate is used as topdressing, it is important to remember not to apply it after the rain or before the dew is dry. Ammonium bicarbonate should not be sprayed on the surface of soil no matter it is used as base fertilizer or topdressing, so as to prevent nitrogen volatilization, loss of nitrogen or damage to crops. At the same time, it is necessary to avoid high temperature season and high temperature period, and try to apply it in the season when the temperature is lower than 20 ℃.

Diammonium phosphate

Diammonium phosphate is a kind of quick acting fertilizer with high concentration, which is suitable for all kinds of crops and soils, especially for the crops that like ammonium and need phosphorus. It is suitable to be used as base fertilizer. If it is used as topdressing, it should be applied as early and deep as 10 cm before covering the soil. It should not be too close to the crops to avoid burning the crops. When it is used as seed fertilizer, it can not be directly contacted with the seed. Do not apply diammonium phosphate with water, otherwise most of the nitrogen in it will remain on the surface of the ground, and should not be mixed with alkaline fertilizers such as plant ash and lime to prevent nitrogen volatilization and reduce the availability of phosphorus. We can also use NPK fertilizer granulator to further process it into high-quality compound fertilizer.

The complete set of automated organic fertilizer production line includes: manure dewatering machine, fermentation tipping machine, organic fertilizer crusher, organic fertilizer mixer, organic fertilizer granulator, rotary dryer, cooling machine, drum screening machine, automatic packaging machine, belt conveyor, coating machine, etc.

1. Organic fertilizer tipping machine: Its function is to mix animal manure with crushed crop straw, undergo high-temperature fermentation and decomposition, deodorize and sterilize, completely eliminate harmful bacteria in the material, and prepare for the next process;

2. Organic fertilizer crusher: Crush fermented materials, the finer they are, the more rounded the particles produced, and the better their appearance;

3. Forklift feeding silo: plays a role in uniform feeding and does not cause material to accumulate at the feeding port;

4. Horizontal mixer: adding elements such as nitrogen, phosphorus, and potassium, bidirectional spiral stirring is more uniform, suitable for mixing various materials;

5. Organic fertilizer granulation machines: Organic fertilizer granulation machines are divided into three types of conventional granulation equipment: disc granulation machines, toothed granulation machines, and three-in-one composite granulation machines. The prices of the three types of granulation equipment are completely different, and customers need to customize them according to their own needs;

6. Organic fertilizer dryer and cooler: The hot air is introduced into the dryer through an induced draft fan to dry the raw materials. The moisture content of the dried raw materials does not exceed 30%. Due to the high temperature of the dried particles, a cooling machine is needed to cool them down;

7. Drum screening machine: The function of this equipment is to screen out particles that do not meet the standard size, and transport them to the crushing process through a belt conveyor for new crushing and granulation. The qualified particles will be transported to the encapsulation process through screening;

8. Organic fertilizer coating machine: Add a layer of coating agent outside the particles to make the appearance of the particles more round and beautiful, sell well, and facilitate long-term storage of materials;

9. Fully automatic quantitative packaging scale: This equipment is the last process in the organic fertilizer production line, and its function is to automatically package particles, with the advantages of saving labor and more accurate packaging.

The organic fertilizer production line can effectively solve the environmental pollution caused by organic waste in animal husbandry, reduce surface water eutrophication caused by pollution, and improve the safety and quality of agricultural products. Fully consuming human green and organic food has laid a good foundation, and the ecological and environmental benefits are extremely significant.

The nutrients contained in sheep manure and urine are relatively abundant, not only having highly soluble organic nutrients that can be digested and absorbed by crops, but also slow acting nutrients that are not easily soluble. They are good fertilizers that closely combine fertility and speed. Sheep manure organic fertilizer can improve soil layers, avoid land resource agglomeration, and enhance economic value.

The operating steps for fermenting sheep manure organic fertilizer production line to produce organic fertilizer:

1. Collect sheep manure and mix it with auxiliary materials such as sawdust, straw, and fungal residue in proportion. The amount of auxiliary materials added is determined by the moisture content of sheep manure, and the water content can be controlled to be around 45%. That is, hold it in a ball and see water between the fingers but do not seep, and it will disperse on the ground.

2. The mixed materials are invested in the fermentation tank and gradually aerobic fermentation is carried out. The fermentation temperature is controlled at 60-70 ℃, and the organic fertilizer tipping machine is used to flip it every two days. The function of flipping is to increase the oxygen content of the material, accelerate the fermentation process, adjust the material temperature, and the tipping machine also has crushing and moving functions, making the material more evenly mixed. The fermentation time is generally 5-10 days, and the fermentation materials should have a loose appearance, a dark brown color, and no foul odor.

3. After the fermentation of the material, it must be crushed by a biomass fuel crusher and ground into powder, which is beneficial for mid to late stage granulation. The biomass fuel crusher is mixed with materials containing very water and a certain viscosity. The particle size distribution of the crushed materials is classified broadly, and the feed particle size distribution is below 16 mesh.

4. After crushing the material, it can be granulated using an organic fertilizer granulator. The granulation methods include disc granulator, drum granulator, and roller to roller extrusion granulator. Generally speaking, the production capacity of roller to roller extrusion granulator is higher than that of disc granulator, and the production capacity of drum granulator is higher than that of roller to roller extrusion granulator. Therefore, the suitable granulation method can be selected based on the production capacity of the processing plant.

5. After granulation, it needs to undergo air drying and dehydration. According to our organic fertilizer regulations, the moisture content of the product’s organic fertilizer must be less than 20%.

6. After air drying, the organic fertilizer particles are screened by screening equipment and tested to meet the standards before being packaged and sold in the market.

The development of green agriculture and the control of fecal pollution ecological environment also need the assistance of organic fertilizer equipment. The organic matter microorganisms contained in the field soil need to be adjusted and improved through the organic fertilizer produced by the organic fertilizer equipment. Long term correct application of organic fertilizer can not only completely improve soil structure, but also make due contributions to the construction and development of green agriculture.
