The production equipment of biological fertilizer project mainly includes fermentation part and granulation part. Even if organic fertilizer raw materials are well fermented, granulation is difficult, because organic raw materials are characterized by rough raw materials, light weight and low binding rate.
The bio organic fertilizer production line includes main equipment:
1. New type organic fertilizer granulator: designed and manufactured by the new process of wet continuous granulation. The machine can not only granulate a variety of organic materials, especially coarse fiber materials that are difficult to granulate by conventional equipment.
2. Tipping machine: used for tipping and composting to improve fermentation speed and quality.
4. Conveyor: it is suitable for conveying loose materials or box items in coal, metallurgy, mining, chemical industry, building materials, wharf, warehouse and construction site, especially in chemical fertilizer plant, cement plant and other environments.
5. Packaging scale: the packaging scale is mainly composed of automatic quantitative packaging scale (composed of storage hopper, feeder, weighing bag hopper, pressing mechanism, computer control, pneumatic actuator, etc.) and optional items (conveyor, sewing machine, etc.)/ Heat sealing machine).
There are several key factors to pay attention to in the selection of equipment: fermentation mode, organic raw materials, degree of mechanization and annual output. The quality of organic fertilizer depends on the fermentation site and the formula of the product.
The key factors of fermentation are: microorganism, carbon nitrogen ratio, carbon phosphorus ratio, water, pH value and aeration control. If a factor is not well controlled, it will cause incomplete fermentation, incomplete fermentation or too long fermentation time.
The formula of organic-inorganic compound fertilizer is the same as that of inorganic fertilizer. It also depends on different soils and different crop formulations. If the fermentation is properly prepared, the effect is better than inorganic fertilizer and the cost is low. As a green fertilizer, it can also improve the environment of plant survival and soil granulation.
The technical content of biological fertilizer project is high. In addition to the biological agents that promote the maturation and decomposition of organic matter in the maturation process, in order to achieve targeted maturation and deodorization, microbial products with specific functions need to be added to enhance the effect of the products.
At present, bio organic fertilizer is included in the category of microbial fertilizer in China, and more strict management measures are implemented than organic fertilizer to promote the healthy development of organic fertilizer.
1. The production process of bio organic fertilizer production enterprises registered with the Ministry of agriculture is basically engaged in the production of microbial fertilizer. In the process of fermentation production, tank stacked fermentation is mostly used, and there are other fermentation methods, such as flat stacked fermentation and fermentor fermentation.
In the process of fermentation and maturation, the adjustment of material moisture, carbon nitrogen ratio and temperature and the use of curing agent are the production process. The key is that the application of fungicide directly affects the fermentation cycle and the maturity of materials. The ripening material basically achieves the harmlessness of the product and is also conducive to the survival of the functional bacteria added in the post-treatment process.
2. In terms of post-treatment of fermentation materials, most enterprises add functional bacteria for compound molding. The dosage form of the product is mainly powder, and some are granulated by rotary drum fertilizer granulator or roller granulator. Granular products prevail over powdered products. The disadvantages of poor appearance and low grade not only improve the commerciality of the product, but also increase the production cost of the enterprise, which has a certain impact on the survival of effective bacteria.
3. The utilization of strains and microbial strains is the core of bio organic fertilizer products. In the production process, there are generally two links related to the utilization of microorganisms:
First, add decomposition bactericide to promote material decomposition and decompose and deodorize in the decomposition process. It is mainly composed of complex strains.
Common strains include photosynthetic bacteria, lactic acid bacteria, yeasts, actinomycetes, Penicillium, wood fungi, etc; Second, the functional bacteria added after material decomposition, generally nitrogen fixing bacteria, phosphorus solubilizing bacteria, silicate bacteria, lactic acid bacteria, Pseudomonas, actinomycetes, etc., play a specific role as fertilizer in the product.
Therefore, the selection and use of microbial strains for the production of bio organic fertilizer is a core technology. Only by mastering this key technology can we accelerate the decomposition and maturity of materials, Ensure the application effect of the product.
Conditions for constructing small organic fertilizer production line
What conditions do we need to build a small organic fertilizer production line? Small organic fertilizer production line can be a powder organic fertilizer production line, or can be a granular organic fertilizer production line.
The production lines of organic fertilizer with an annual output of less than 20000 tons are small organic fertilizer production lines. According to the planning of most customers, the small organic fertilizer production line has 5000 tons, 10000 tons, 15000 tons and 20000 tons.
Because the production line of powdery organic fertilizer is the component of the production line of granular organic fertilizer, we will use the granular organic fertilizer production line to elaborate the technology of small organic fertilizer production line today. The technology of fertilizer production line will be clear.
Process flow of granular organic fertilizer production line:
So, what conditions do we need to build a small organic fertilizer production line?
(1) The construction of small-scale organic fertilizer production line meets the requirements of environmental protection policy. Environmental protection is not only the desire of the people, but also the policy demand for environmental protection for the development of agriculture and animal husbandry;
(2) Raw material source, radius of raw material source, determine your plant location, site investment, transportation investment, etc;
(3) The types of raw materials, the specific equipment types used in each stage of the process, and the investment price of the equipment are affected;
(4) The production scale, the production capacity of small organic fertilizer production line from 3000 tons to 20000 tons determines the equipment capacity requirements, thus affecting the price;
(5) The recycling of resources mainly depends on a variety of agricultural pollution waste recycling methods, such as fuel and electricity raw materials, and biogas residue is used as organic fertilizer raw material;
(6) Other small organic fertilizer production line technology, can be used as feed.
(7) Site: the size of production site and investment of site scale shall be determined according to the planned production scale.
1. The pre fermentation and turning equipment mainly plays the role of composting and material turning, and is more suitable for microbial fermentation to store manure into fertilizer. The technology requires that the viscous storage manure can be effectively mixed with microbial preparation and straw powder. It can not only ferment fast, but also prevent the production of harmful odor gas in fermentation process, which meets the environmental protection requirements.
2. The special pulverizer for organic fertilizer is mainly used for better crushing and fermentation materials, which lays a solid foundation for the next scheme provider. When choosing organic fertilizer pulverizer, we must choose the suitable ones for their own use, and do not blindly. If selected, otherwise, the crushing effect will not be reached, but the normal operation of the next process will be affected.
3. Organic fertilizer mixer is used for mixing formula fertilizer, adding various substances, mixing evenly, and carrying out the next process.
4. The granulator of organic fertilizer mainly plays a role in granulation. The mixed material is uniformly fed into the granulator by conveyor for deep granulation. It can be made into various sizes and shapes according to the local market. There are many kinds of granulator styles and models, and the appropriate granulator can be selected according to the production and requirements of customers.
5. The dryer mainly acts as evaporation material moisture. Because of the large water content in the granulation process of fertilizer granulator, it can not meet the national requirements. The granulation can not be packed immediately, and the moisture should be dried by drying equipment. Evaporation to the state of national standards for the next process.
6. cooling machine. Because the temperature of the dried material is high, it can not be packed immediately, and the woven bag is easy to be burned. The temperature of material needs to be reduced to constant temperature quickly through cooler to carry out the next process.
7. The screen separator mainly plays a role of grading. Because of the granulator granulation rate, the difference of dryer and cooling opportunity, and the particle damage, it is necessary to distinguish the finished particles from the inferior products. After the next procedure, the defective products will be re comminuted and the granulation cycle work will be carried out.
8. Automatic packaging machine mainly plays the role of finished product particles, automatic.
In the process of making a series of special fertilizers, inorganic nutrients and minerals should be added according to different soil conditions and different crops. These minerals are concentrated in organic matter and trace elements, so that the fertilizer contains various nutrients needed for plant growth, such as nitrogen, Phosphorus, potassium, sodium, manganese, zinc, copper, etc.
According to the formula, nitrogen, phosphorus, potassium and fermentation material are mixed by computer and transferred to granulator for granulation. We mix organic and inorganic materials according to different series of products, and mix them well in blender. Assume that the proportion of organic materials is 12%, about 12 tons.
The production process should not be exposed to high temperature and other characteristics due to the poor formation conditions of bio fertilizer mainly composed of organic matter and cellulose and the viable bacterial population with the function of making fertilizer.
Disc granulation and drum granulation are not suitable for building materials, because these two technologies require fine grinding of raw materials, high moisture content of granulation, and generally the moisture content is about 30%, so the load is relatively large. There are different types of fertilizer granulators for your fertilizer granulation process.
For drying, the loss of effective bacteria is great, and the pelleting rate is low (about 60% – 70%), the dust is heavy, and the operating environment in the production process is poor.
Therefore, through the extrusion environment, the requirements of raw material crushing are low, the molding rate is high (more than 95%), the water content of formed particles is low, the drying load is low, the environment is dry, and the production of organic biological functions should be better. Can reduce the loss of effective bacteria, less dust and good working environment.
70 tons of organic fertilizer raw materials, using organic fertilizer special granulator. After granulation, the material is sent to the dryer by belt conveyor for drying. The particle size is 3.0-4.0 mm, and the granulation rate is more than 70%.
The recommended pelletizer is a new type of pelletizer for organic fertilizer.
(4) Drying (fertilizer dryer)
In the production process of biological fertilizer, not only does the moisture content of granules generally exceed the index after molding and need low-temperature drying, but also the moisture content of organic matter after fermentation is about 30% – 40%, and the granule after granulation is generally between 15% – 20%, which needs drying treatment, because the moisture content of fertilizer quality index is less than 14%.
The drying stage is an essential and important process in the production of biological fertilizer, which directly affects the yield, quality and energy consumption. It is very important to choose the type and specification of dryer and control the process conditions.
In order to avoid the death of effective living bacteria due to the high temperature in the drying process, the drying temperature of materials should not be higher than 60 ℃ (usually about 50 ℃). Therefore, the temperature of hot air in contact with materials should be different.
For the moisture content of different materials, generally not more than 130 ℃, it is better to control the hot air temperature by stages, which can not only improve the thermal efficiency, but also effectively avoid the death of living bacteria.
According to these characteristics, the belt dryer is suitable, because it is suitable for low temperature and low humidity drying, and it can control the temperature of hot air in sections to ensure that the material temperature is not higher than the drying temperature, and maintain the highest temperature in the whole process.
The tail of the dryer can also add natural air cooling part, and cool the material immediately after drying, It can be used many times.
It is very suitable for granular biological fertilizer, with drying permeability, stable and uniform drying of materials, no damage to particles, adjustable residence time and feeding speed to achieve the best drying effect, because most of the thermal circulating air has high thermal efficiency, and the heat source can be used.
There is a secondary granulation area in front of the steam dryer provided by the biogas boiler, The material can be granulated there. Then, the material is lifted up through the plate to be completely dried. The exhaust machine exhausts the humid hot air through the pipe at the end of the dryer, and the air enters the precipitation chamber for precipitation.
After precipitation, the tail gas is removed by the washing tower, and the ejected water is pumped out for recycling. After secondary dust removal, the waste gas is discharged into the atmosphere through the chimney.
(5) Cooling (drum cooler)
The dry material is cooled by belt conveyor and sent to cooler. The cooling process mainly includes using fan to send natural air to cooler through pipe to cool the material.
The wind direction in the cooler is counter current. The waste gas pumped into the settling chamber by fans and pipes is treated and discharged into the atmosphere as dry waste gas
After cooling, the material is screened, the crushed large particle material and the screened powder are transported to the granulator through the return belt for granulation, and the final product is packaged in the automatic packaging system.
Crops are good organic fertilizers. But we often find that when using crops, fertilizer sometimes leads to a large number of soil diseases and insect pests, And it increases year by year. I have been doing tests for several years and achieved good results. Now I have become a common element in fertilizer treatment to be faithful to agriculture.
1. Flatten poultry feces, dry in the sun, mash fine powder, and mix 1 kg of thiophene per cubic meter. After the round table is piled up, mix evenly and smear with flat mud for 15-20 days.
2. Mix fresh cow dung and sheep ash with 30% ash, then spread to 10 cm thick and spray 1 kg liquid per square meter. Liquid preparation: water 1605, carbendazim ratio 100:0.2:0.3.
3. When exposed to the sun, half human manure should be piled into a truncated cone of 50cm in the shape of a high platform, with flat mud paste, and several drugs on the top of the cork should be used to penetrate the hole, with the depth of 40cm, and then filled with liquid.
Liquid preparation: the ratio of water to trichlorfon was 100:0.5.
