Organic fertilizer production line processing green organic fertilizer enhances agriculture

Application of traditional organic fertilizer Application of traditional organic fertilizer has a long history. Up to now, it is still the main method of applying base fertilizer in autumn and winter in most orchards. The common methods in production are compost, chicken manure, cow manure, pig manure, sheep manure and other animal manure and human manure. Among them, sheep dung is a natural green fertilizer, containing 4%~27% organic matter, more than other animal dung, rich in nitrogen, phosphorus and potassium nutrition, fine dung and thick fertilizer, belonging to thermal fertilizer. Chicken dung contains rich nutrients, especially the crude protein in chicken dung. The content of organic matter reaches 25.5%. Through proper processing and utilization of organic fertilizer production line, it can become a better green organic fertilizer.

Enhance crop resistance to disease, drought and waterlogging

Organic fertilizer contains vitamins and antibiotics, which can enhance crop resistance and reduce or prevent disease. After applying organic fertilizer into the soil, it can enhance the water storage and water retention capacity of the soil, and enhance the drought-resistant capacity of crops under drought conditions.

At the same time, the organic fertilizer processed by the organic fertilizer production line can also make the soil loose, improve the ecological environment of crop roots, promote the growth of roots, enhance root vitality, improve the waterlogging tolerance of crops, reduce plant mortality, and improve the survival rate of agricultural products.

Improve the safety and greenness of food

The state has clearly stipulated that the excessive use of inorganic fertilizers must be restricted in the agricultural production process, and organic fertilizers are the main source of fertilizer for the production of green food.

Due to the complete variety of nutrient elements in organic fertilizers and the fact that these substances are non-toxic, harmless and pollution-free natural substances, this provides the necessary conditions for the production of high-yield, high-quality and pollution-free green food. Humic acid substances mentioned above can reduce the harm of heavy metal ions to plants, which is equivalent to reducing the harm of heavy metals to human body.

Increase crop yield

The beneficial microorganisms in the organic fertilizer processed by the organic fertilizer production line utilize the organic matter in the soil to produce secondary metabolites, which contain a large number of growth-promoting substances.

For example, auxin can promote the elongation and growth of plants, abscisic acid can promote the ripening of fruits, gibberellin can promote the flowering and fruit setting, increase the number of flowering and fruit preservation rate, improve the yield, make the fruit plump, fresh and tender in color, and can be listed early to increase production and income.

Reduce nutrient loss and improve fertilizer utilization

The actual utilization rate of fertilizer is only 30%~45%. Some of the lost fertilizer is decomposed and released into the atmosphere, some is lost with the water and soil flow, and some is fixed in the soil and cannot be directly absorbed by plants.

When organic fertilizer is applied, the beneficial biological activities improve the soil structure, increase the soil water and fertilizer retention capacity, and reduce the loss of nutrients. In addition, the effective utilization rate of fertilizer can be increased to more than 50% by the effect of phosphorus and potassium hydrolysis by beneficial microorganisms.

To sum up, the benefits of organic fertilizer processed by organic fertilizer production line to agriculture illustrate its advantages. With the improvement of people’s pursuit of food safety and quality of life, the development of green agriculture will accelerate the application of organic fertilizer in the future, and also truly meet the requirements of sustainable development of modern agriculture.

Organic fertilizer production line processes domestic sludge to produce fertilizer

fertilizer granulator Feb 21, 2023

Organic fertilizer production line processes domestic sludge to produce fertilizer

1. Adjust the moisture content of raw materials: the water content of sludge from the water treatment plant is generally relatively high, about 75% – 80%. It is generally anaerobic fermented, and the content of harmful bacteria is not high. When it is transported back to the fermentation plant, the raw materials with low moisture content should be placed under the fermentation tank, and then the water-absorbing auxiliary materials, such as domestic garbage and crushed crop straw and branches, should be placed above to make full use of the liquid organic fertilizer, It can increase all kinds of nutrients in the raw material to be sufficient, and the water content of the material in the fermentation can be 50% – 55%.

2. Adding sludge starter (special starter for sludge reduction): adding special starter for sludge reduction to the sludge is generally added before fermentation, and the fermentation bacteria are evenly mixed with the sludge through the function of throwing and stirring by the tilting machine. The addition amount of composite starter is generally about 0.1% – 0.3%. Just put the sludge starter into the sludge.

3. Fermentation of organic fertilizer composter: after high-temperature fermentation, it can effectively kill pathogenic microorganisms and ascaris eggs in the sludge, fix heavy metals in the microorganisms, or turn them into insoluble carbonates, and prevent heavy metals from entering the food chain. There are two kinds of fermentation methods: ground strip fermentation using ground tipper; And trough-type tipping fermentation with trough-type tipping machine. The production process of sludge organic fertilizer introduced this time uses the tank type fermentation tipping machine.

4. Material crushing: because the fermented material contains small lumps, which is not conducive to the granulation of the finished product, the material can be crushed at this time, and the organic fertilizer crusher can be used.

5. Material mixing: the crushed materials are transported to the batching bin, then sent to the main conveyor through automatic batching, and then sent to the mixer for mixing.

6. Material granulation: small and medium-sized organic fertilizer plants generally use disc granulator to granulation, which can save investment costs and achieve a high pelletizing rate of more than 93%. There are three kinds of particles: large, medium and small. The angle of the granulation disk must be adjusted to a certain position. The angle depends on the size of the particles. The larger the angle, the smaller the particles. The smaller the angle, the larger the particles.

7. Drying and cooling of organic fertilizer: the granulated semi-finished organic fertilizer particles are sent to the dryer through the main conveyor for drying, and the dried finished organic fertilizer particles are sent to the primary screening machine through the conveyor to sort out large, medium and small particles. The larger particles are sent to the pulverizer through the return belt for crushing and re-granulation. The medium and finished materials are sent to the cooler through the conveyor for cooling, because the particles have a certain temperature, the particles are sent after cooling, The fine powder is separated by two sieves.

8. Finished product packaging: the screened finished organic fertilizer particles are sent to the organic fertilizer automatic packaging machine through the conveyor, and the finished bio-organic fertilizer can be produced by measuring and packaging.

Which manure in the organic fertilizer production line is suitable for fertilizer

fertilizer granulator Feb 21, 2023

Manure is rich in organic matter and various nutrients required by crops, which has a good effect on increasing crop yield and improving soil fertility, and has been widely used in agricultural production. However, in recent years, the irrational use of manure has also increased significantly. If manure is used in the wrong place, it will not only have a good effect, but also backfire. Let’s briefly introduce it today.

Main components of various livestock manure:

Pig dung

Pig manure contains 15% organic matter, 0.5% nitrogen, 0.5~0.6% phosphorus and 0.35~0.45% potassium. Pig dung has a fine texture and complex composition, including protein, fat, organic acid, cellulose, hemicellulose and inorganic salt. Due to the large amount of nitrogen, the proportion of carbon and nitrogen is small, about 14:1. Generally, it is easy to be decomposed by microorganisms and release nutrients that can be absorbed and utilized by crops. Pig manure has the highest humus content, the largest amount of cation exchange, and the strongest fertility retention, but it has more water content and less cellulosic decomposing bacteria. Mixing a small amount of horse manure to inoculate cellulosic decomposing bacteria can greatly increase fertilizer efficiency.

cow dung

Cow dung contains 14.5% organic matter, 0.30~0.45% nitrogen, 0.15~0.25% phosphorus and 0.10~0.15% potassium. The content of organic matter and nutrients is relatively low among all kinds of livestock, with fine texture, high water content, slow decomposition and low calorific value, which is a slow-acting fertilizer. Due to its high water content, poor aeration and difficult decomposition of organic matter, cow dung is a cold fertilizer.

Horse dung

Horse manure contains 21% organic matter, 0.4~0.5% nitrogen, 0.2~0.3% phosphorus and 0.35~0.45% potassium. The components of horse dung are mainly cellulose and hemicellulose. In addition, it also contains lignin, protein, fat, organic acid and various inorganic salts. The water in horse dung is easy to evaporate, and contains more cellulolytic bacteria. It is a thermal fertilizer. Applying horse dung can improve the properties of clay.

Sheep dung

Sheep dung contains 24-27% organic matter, 0.7-0.8% nitrogen, 0.45-0.6% phosphorus and 0.4-0.5% potassium. Sheep dung contains more organic matter than other animal dung, which is fine and rich in fertilizer. Sheep dung has a fever between horse dung and cow dung. It is also a thermal fertilizer, also known as thermal fertilizer. It can be applied on sandy soil and clayey soil with good effect.

Bird dung

The poultry manure contains 25.5% organic matter, 1.63% nitrogen, 1.54% phosphorus, 0.85% potassium, 11% carbohydrate, 7% fiber, and fresh poultry manure has a high water content. The nitrogen in poultry manure (chicken manure, duck manure, goose dung, pigeon dung, etc.) is mainly uric acid, which can not be directly absorbed by crops and is harmful to the growth of crop roots. At the same time, fresh poultry manure is easy to attract underground pests.

The organic fertilizer production line uses modern microbial technology, mainly livestock and poultry excrement, and bran, peanut shell powder, crop straw and other auxiliary materials as carriers. The bacteria and livestock and poultry excrement are fully mixed by mixing method, so that the microbial strains are connected to the livestock and poultry excrement, including dehydrator, fermentation turner, semi-wet material crusher, horizontal mixer, granulator, dryer, cooler, drum screening machine, coating machine, packaging equipment The bio-organic fertilizer produced by belt conveyor and other equipment after a series of harmless treatment such as rapid heating, fermentation, ripening and deodorization.

Organic fertilizer equipment plant turns domestic sludge into green organic fertilizer

fertilizer granulator Feb 21, 2023

In order to ensure that we all have clean domestic water, almost every city has a sewage treatment plant. However, the domestic sludge produced by the sewage treatment plant has always been a headache for the environmental protection department, because these sludge are rich in a large number of organic substances and pathogenic bacteria, insect eggs, weed species and heavy metal ions, which are easy to produce stench, mosquitoes and flies, and pollute the environment. At present, three treatment methods are mainly used: landfill, reclamation and incineration. The existing treatment methods are easy to cause secondary environmental pollution and waste a large amount of organic fertilizer resources.

Domestic sludge is produced after treatment of domestic sewage. Domestic sewage is produced in toilets, kitchens and bathrooms. Therefore, domestic sludge is “nutritious”. The content of organic matter in domestic sludge after bacterial fermentation is generally as high as 50%, and the indicators of nitrogen, phosphorus and potassium are between 5% and 7%, while the content of heavy metals is very low, which meets the basic standard of organic fertilizer and can be used as fertilizer.

After microbial fermentation treatment, domestic sludge can be turned into bio-organic fertilizer through the organic fertilizer production line, which is suitable for trees, flowers, lawns and used as a nursery substrate for tree containers. It has achieved good growth effects, and the physical, chemical and biological properties of the soil have been improved. Thus, the resource utilization of domestic sludge is completely realized.

For the address of the domestic sludge organic fertilizer plant, the overall planning principles are as follows: the raw materials are nearby, the site transportation is convenient, the infrastructure is good, the original buildings are used as much as possible, the investment scale is reduced, the capital use efficiency is improved, and the project demonstration function is fully played. Keep away from residential areas and choose downdraft; Adjust measures to local conditions, compact layout, and try to use the abandoned land: separate the living area from the plant site to maintain environmental sanitation.

The application of bio-organic fertilizer produced by sludge can improve the soil activity and effectively repair the hardening of soil caused by long-term application of inorganic fertilizer: it is conducive to the absorption of crops and the balance of nutrients, and the active bacteria group can greatly promote the effective release of residual nitrogen, phosphorus, potassium and other nutrients in the soil. Using biological fermentation to treat the sludge from urban sewage treatment plants can greatly reduce the pollution of domestic sludge to cities and land. At the same time, the organic fertilizer produced can reduce the application of chemical fertilizers and make agricultural products more environmentally friendly.

Select appropriate product configuration and construction scale of organic fertilizer production line

fertilizer granulator Feb 21, 2023

Select appropriate product configuration and construction scale of organic fertilizer production line

The equipment investment scale and product selection plan of the manure organic fertilizer production line need to be formulated according to the following conditions: characteristics of raw material resources, local soil conditions, local planting structure and main crop varieties, comprehensive consideration of local resources, market capacity, and market coverage radius. Generally, the annual output of small newly-built plants is 10000 tons (1.5-2.5 tons/hour), 20000 tons (2.5-3.5 tons/hour) and 30000 tons (4.5-6 tons/hour). The annual output of medium-sized plants is 30000 to 50000 tons, and that of large plants is 50000 to 100000 tons. The investment scale and production line scheme design shall be formulated according to the characteristics of raw material resources, local soil conditions, local planting structure and main crop varieties, plant site conditions, production automation degree and other conditions.

The construction scale of general organic fertilizer production line configuration is generally 5000 tons to 100000 tons per year. Local resources, market capacity and market coverage should be comprehensively considered.

The manure organic fertilizer production line has three configurations: high, middle and low. Large fertilizer plants need to adopt a complete set of production configurations, and the appearance and nutrient content of the finished products can meet the market requirements. It has a great advantage in the promotion of the finished organic fertilizer. The medium-low configuration organic fertilizer production line is suitable for small and medium-sized fertilizer plants. The sales scope of finished organic fertilizer is limited to nearby areas. Some processes in the organic fertilizer production process need to be completed manually.

If the daily output of animal excrement exceeds 5 cubic meters and the maximum output of animal excrement does not exceed 10 cubic meters, you can purchase simple facilities, mainly mobile tipping machines (tipping machines), shredders and other facilities, and the investment cost of the facilities will need 100000 to 300000 yuan. If the daily output of livestock and poultry excrement exceeds 10 cubic meters, it is recommended to provide more equipment, which generally requires an investment of 300000 to 600000 yuan, and a complete equipment may require more than 1 million yuan.

Site selection: general planning principles: raw materials are nearby, site transportation is convenient, infrastructure is good, original buildings should be used as much as possible, investment scale should be reduced, capital use efficiency should be improved, and project demonstration function should be given full play. Keep away from residential areas and choose downdraft; Adjust measures to local conditions, compact layout, and try to use the abandoned land: separate the living area from the plant site to maintain environmental sanitation.

Benefits of organic fertilizer equipment processing and production to sustainable agricultural development

fertilizer granulator Feb 21, 2023

Developing bio-organic fertilizer is one of the key ways to ensure the development of high-efficiency agriculture. Bio-organic fertilizer refers to a kind of special organic fertilizer that contains microbial strains with specific functions and has a secondary solid fermentation stage in the production process. After the bio-organic fertilizer processed by the organic fertilizer production line is applied to the soil, sufficient organic matter is used to provide sufficient energy materials for the exogenous functional microorganisms, so that these exogenous functional microorganisms are easy to colonize and reproduce in the soil, After the growth of crop roots, a large amount of root exudates will be secreted. These exogenous functional bacteria that have been colonized in the soil can converge to the root surface and rhizosphere, realize the regulation of rhizosphere microbial flora, and play the role of rhizosphere beneficial bacteria in activating nutrients, stimulating the growth of plant roots, and antagonizing soil-borne pathogens.

Improve soil fertility

95% of the trace elements in the soil exist in an insoluble form and cannot be absorbed and utilized by plants. The microbial metabolites contain a large number of organic acids. These substances, like hot water added in ice, can quickly dissolve the trace elements such as calcium, magnesium, sulfur, copper, zinc, iron, boron, molybdenum and other essential mineral elements of plants, and become nutrient elements that can be directly absorbed and utilized by plants, It has greatly increased the fertilizer supply capacity of the soil.

The organic matter in the organic fertilizer processed by the organic fertilizer production line increases the content of organic matter in the soil, reduces the soil cohesion, and strengthens the water and fertilizer retention performance of the sandy soil, so that the soil forms a stable granular structure, which can play a good role in the coordinated supply of fertility. After using organic fertilizer, the soil will become loose and fertile.

Improve soil quality and promote soil microbial reproduction

Organic fertilizer can make soil microorganisms multiply in large numbers, especially many beneficial microorganisms, such as nitrogen-fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, etc These beneficial microorganisms can decompose organic matter in soil, increase soil aggregate structure and improve soil composition.

Microorganisms reproduce very quickly in the soil. They are like an invisible net, and are complex. After the bacterial body of microorganism dies, a lot of tiny pipes are left in the soil. These tiny pipes not only increase the permeability of the soil, but also make the soil become fluffy and soft, and the nutrient water is not easy to lose, which increases the soil’s water and fertilizer storage capacity, and avoids and eliminates the soil’s hardening.

The beneficial microorganisms in the organic fertilizer processed by the organic fertilizer production line can also inhibit the propagation of harmful bacteria, so that less pesticide can be applied. If applied continuously for many years, it can effectively inhibit soil harmful organisms, save labor, money and no pollution.

At the same time, there are various active enzymes secreted by animal digestive tract and various enzymes produced by microorganisms in organic fertilizer. After these substances are applied to the soil, the enzyme activity of the soil can be greatly improved. Long-term and sustainable use of organic fertilizer can improve soil quality. If the quality of soil is fundamentally improved, we are not afraid of not producing high-quality fruit.

Provide comprehensive nutrition for crops and protect crop roots

Organic fertilizer contains a large number of nutrients, trace elements, sugars and fats required by plants. CO2 released from decomposition of organic fertilizer can be used as material for photosynthesis.

Organic fertilizer also contains 5% of nitrogen, phosphorus and potassium, and 45% of organic matter, which can provide comprehensive nutrition for crops.

At the same time, it has to be mentioned that organic fertilizer decomposes in the soil and can be transformed into various humic acids. It is a kind of macromolecular material with good complexing adsorption performance and has good complexing adsorption effect on heavy metal ions. It can effectively reduce the toxicity of heavy metal ions to crops, prevent them from entering the plant, and protect the roots of humic acid substances.
