Plant ash is the residue of firewood after combustion. It belongs to alkalinity. The main component is potassium carbonate (K2CO3) which can be used as fertilizer. Before the widespread use of chemical fertilizers, agricultural plant ash refers to the ash produced after burning and eating by mountain grass, straw and branches (excluding the ash produced by coal).
Plant ash shall not be mixed with other fertilizers during storage. Some farmers are used to putting ash in puddles and mixing it with organic fertilizer and straw, which is very wrong. Because the ash is alkaline, it will cause the volatilization of nitrogen in organic fertilizer and reduce fertilizer efficiency. Such treatment will not only waste fertilizer, but also pollute the environment.
Ashes must be applied separately. Plant ash cannot be mixed with organic farm manure and ammonium nitrogen fertilizer to avoid nitrogen volatilization loss, nor can it be mixed with phosphorus fertilizer to avoid phosphorus fixation and reduce the use efficiency of phosphorus fertilizer.
Therefore, when planning the fertilizer manufacturing process and using plant ash as organic raw material, the fertilizer plant should pay attention to the proportion of raw materials.
1. Soil application: since the ash is alkaline, cohesive soil, acidic or neutral soil should be used. Soil application can be used as base fertilizer, seed fertilizer and topdressing, as well as seedling raising and seedling covering (seed covering fertilizer).
When used as base fertilizer and seed fertilizer, the amount of fertilizer should not be too large, and should be isolated from seeds to prevent seed burning. Generally, 50-100kg per mu is appropriate.
It is suitable for centralized soil application, strip application or hole application, with a depth of 8-10cm, and covered with soil after construction. Mix the wet soil 2-3 times or spray a little water before application.
2. Topdressing outside the root: more than 90% of the potassium contained in plant ash is soluble in water, which is a quick acting potassium fertilizer. According to this characteristic, plant ash can be used as extraroot topdressing, that is, 1% concentration of plant ash extract can be used for foliar spraying.
3. Priority crops: plant ash is suitable for various crops, especially potassium free or potassium free and chlorine free crops, such as potato, sweet potato, tobacco, grape, sunflower, sugar beet, etc.
Plant ash can be used for potato, not only for soil application, but also for potato wounds. In this way, it can be used as seed fertilizer to prevent wound infection and decay.
How to improve the product output and output, the key lies in the organic fertilizer granulator.
1、 According to the moisture, fineness and cohesiveness of raw materials.
Powder raw materials form spherical particles through the attachment of water. Therefore, controlling water and making water uniform have become the key factors to improve yield. The lower the moisture content, the lower the granulation rate, the higher the moisture content, the more large particles, the uneven moisture, the smaller the particle size, and the lower the yield.
2. Material fineness
It is needless to say that the material fiber has natural coarse granulation effect, rough and brittle appearance and poor formability. The higher the fineness, the better the formability and the smoother the particles.
3. Is the material sticky
In particular, organic fertilizer granulation, general raw animal manure (chicken manure, pig manure, cow manure, sheep manure, pigeon manure, etc.), straw (corn straw, straw, leaves, etc.), fungus residue, sugar residue, drug residue, monosodium glutamate residue, etc. The viscosity of general materials is poor, so some viscous fillers such as bentonite need to be added.
2、 Fertilizer granulator is selected for organic fertilizer production line.
If columnar is produced, ring mold granulator and columnar extruder are selected.
For irregular and flat ball type, select the appropriate drum extrusion granulator (depending on the die).
All kinds of granulation equipment have their own advantages and disadvantages. Different equipment shall be selected according to raw materials, investment cost (drying or not) and the needs of farmers.
Let’s take a look at the process conditions and process settings of organic fertilizer production.
150000 tons of livestock manure and industrial waste are used, and the actual annual output of finished organic fertilizer is about 100000 tons. The production process is as follows:
1. Floor strip stacker, floor dumper or material fermentation tank, trough dumper.
2. Evenly sprinkle microbial agent, turn over and ferment to reach the temperature, smell, decompose and kill bacteria.
3. Fermentation for 7-12 days, with different times according to different temperatures.
4. Completely ferment and decompose, and then leave the pond (the ground type is directly stacked by forklift).
5. Sieve the thickness with a grading screen（ The filtered powdered fertilizer can be sold directly).
6. The screened large pieces are crushed by the crusher and returned to the grading screen.
7. Mix the required trace elements with a premixer.
8. Granulation with fertilizer granulator
9. Enter the dryer and cooler.
10. Automatic packaging machine for sale.
Fertilizer manufacturing process
1. Soil dumper, or trough type soil Dumper: the soil dumper does not need to build a trough, and directly piles the materials. The wheel soil dumper is used for straddle stacking fermentation. Trough fermentation is adopted. According to your production scale, six fermentation tanks with a length of 6 meters and 40-50 meters are built. The fermented materials are continuously put into the fermentation tank, and the turning machine is used for turning and polishing to control water and mixing. Unified purpose can save a lot of labor. Can achieve the goal of full maturity.
3. Screening machine: the fermented organic fertilizer is screened to separate the large blocks and impurities inside, which is convenient for crushing and packaging.
4. Crusher: separate and crush the large impurities and stones in the screened organic fertilizer to ensure the appearance of the product.
5. Premixer: premix the screened and crushed organic fertilizer to ensure the stability of product quality. At the same time, when adding fertilizer and trace elements, it plays the role of mixing and producing special fertilizer and various compound fertilizers.
6. Granulator. The material is granulated.
7. Dryer and cooler: dry and cool the particles.
8. Packaging machine: organic fertilizer granules are directly granulated and sold.
NPK compound fertilizer has comprehensive nutrition, high content and good physical properties. But how to use NPK compound fertilizer correctly? Three problems should be paid attention to in the application process.
First of all, NPK compound fertilizer should be selected according to different soil and crops. Only in this way can its fertilizer efficiency be exerted. Rice, wheat, corn and other food crops need more nitrogen fertilizer, nitrogen and phosphorus compound fertilizer can be used; Leguminous crops can fix free nitrogen in the air, and can apply phosphorus and potassium fertilizer. Some economic crops can choose ternary or multivariate compound fertilizer suitable for local soil and climate conditions.
The second is the combination of compound fertilizer and simple fertilizer. The nutrient composition of compound fertilizer is fixed. Only when combined with various element fertilizers can the nutrient requirements of crops in different periods be met.
Generally speaking, compound fertilizer should be used as base fertilizer, and simple fertilizer can be used as top fertilizer at peak and critical period. At the same time, organic fertilizer must be applied.
Third, the method should be appropriate. In various compound fertilizers, the proportion and form of various nutrients are different. In addition, soil and crop types are different, so fertilization methods should not be the same, should be treated differently.
Clay soil fertility should be applied deeply, sandy soil fertility can be removed easily, and a small amount of fertilizer can be applied. The compound fertilizer containing ammonium nitrogen should be covered deeply to reduce the loss. How to make npk fertilizer granules at large scale? Go here for more.
The compound fertilizer containing phosphorus and potassium should be applied in a centralized way and near the root system to avoid nutrient fixation and promote the absorption and utilization of crops. Generally speaking, expensive potassium dihydrogen phosphate should not be used as base fertilizer, but as external fertilizer or seed soaking.
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.
Secondly, it is necessary to use semi wet material crusher equipment of organic fertilizer to crush livestock manure and raw materials. Raw material matching is one of the important processes of organic fertilizer production line.
The complete organic fertilizer production line includes three processes
2. It is especially suitable for high viscosity materials. The material of fertilizer granulator should meet the production requirements of pressure, temperature and catalyst resistance, and keep the product clean. Due to the different materials of fertilizer granulator, the production process and structure of fertilizer granulator will be different, so it can be divided into steel, lining equipment, etc.
The complete organic fertilizer production line includes three processes
3. High temperature energy can be obtained after the raw materials are dried, and the next step is to cool them at low temperature. Since water cannot be used for cooling, it is necessary to separate the contact between material and water through cooler. The screening machine will screen unqualified organic fertilizer particles. The screening equipment has the advantages of high efficiency and easy operation. More details, go to https://organicfertilizerplants.com/organic-fertilizer-production-process/
A lot of garbage produced by residents every day can be used, and can be processed into organic fertilizer raw materials after secondary treatment. The market position and broad development prospect of organic fertilizer production equipment can be predicted. Automatic organic fertilizer production line is the most skilled equipment in the industry.
It can work independently without help, and has high precision, avoids the waste of resources, improves the qualified rate of products, and improves the qualified rate of products. Save a lot of unnecessary economic expenditure. It can not only save costs for the company, but also create greater economic benefits for the company, with higher output, so that the goods can enter the market at the fastest speed and the best time, and obtain a higher market share. sales volume.
Today, the development of organic fertilizer production equipment has expanded to high-speed, complete set, highly automated and diversified fields. The diversified development of organic fertilizer production equipment is inseparable from the efforts and struggle of enterprises, because in the face of such a development environment, if we want to further the development of enterprises, we must let the domestic market organic fertilizer production equipment is moving towards the road of automation.
The equipment needed for the production of biological fertilizer will make a difference in the limited market. Some technologically backward, smaller manufacturers will be driven out of the market and forced to shut down. Therefore, if you want to have a larger application group forever, you must do a good job in communication with customers, do a good job in market research, and finally make the organic fertilizer production equipment better meet the demand and serve the public.
So is organic fertilizer. In the past, farmers used accumulated organic fertilizer directly. Nowadays, with the improvement of living standards, high-tech equipment is also used for large-scale production of organic fertilizer. Is to make life more convenient production of production equipment.
Organic fertilizer production line is the production line of organic fertilizer particles and organic fertilizer powder. As we all know, if you want to granulate organic fertilizer, you must first make it into powder, and then granulation, so the powder production line is an important part of the particle production line.
Now, I will introduce the process of the organic fertilizer production line in detail together with the granular organic fertilizer production line. According to the process layout, the process flow of granular organic fertilizer production line is: Fermentation – crushing – mixing – granulation – drying – Screening – Coating – packaging. The technological process of powdered organic fertilizer includes the above four processes (fermentation, crushing, screening and packaging).
The preparations for the construction of the organic fertilizer processing plant are as follows:
1) The construction of organic fertilizer production line should meet the requirements of environmental protection policy. Environmental protection is not only the desire of the people, but also the policy requirement of the development of agriculture and animal husbandry for environmental protection.
2) The source of raw materials and its surrounding radius determine the location of the factory, site investment, transportation investment, etc.
China has a vast territory and rich raw material resources for organic compost equipment. It is understood that the final urine excreted by a pig in a year can be combined with bedding material to produce 2000-2500kg of high-quality organic compost, which is enough for one mu of land to use chemical compost throughout the year. The content of components is more than 6%, and the content of organic matter is more than 35%, which is higher than the national standard.
In the organic compost production line, we can use the drum granulator, or we can equip the drum granulator in the organic compost production line to complete the production process of NPK compost granulator. The granulation method completes the production process. This is different from rolling compost granulator, which usually uses dry granulation method to produce compost granulator.
In the bio organic compost production line, different types and series of compost equipment should be equipped to complete the production process. These machines play different roles in the compost manufacturing process.
In the production of compost granulator, the compost granulator should be designed and equipped on the production line to manufacture bio organic compost granulator. In the biological compost production line, we can use the flat mold granulator to manufacture the biological organic compost granulator, and we can also use the drum granulator. Complete the granulation process on the production line.
Organic fertilizer granulation production line is to use chicken, sheep, pig manure as the main raw materials, add a certain amount of nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, magnesium sulfate, ferrous sulfate and other substances, with rice bran, yeast fermentation, soybean meal and sugar in a certain period of time as a kind of biological bacteria, in the role of sulfuric acid, mixed fermentation equipment to make biological fertilizer.
Process flow of complete set of equipment for biological fertilizer production:
1. Fermentation: collect poultry feces and urine, mix with hay and rotten silage to make compost, and then ferment. In the fermentation process, the cow dung is completely fermented by the stacker, which can only be achieved by stacking in time and evenly.
2. Raw material comminution and mixing: use the raw material bin to mix composting materials, N, P, K and other inorganic fertilizers, other additives and other raw materials, and pass through the pulverizer and horizontal mixer in proportion. Mix.
3. Pelletizing: use a new type of organic fertilizer drum pelletizer to pelletize materials.
6. Cooling: cooler is used to cool granular materials, which is helpful for the storage and quality of particles.
7. Packaging: the granular materials cooled by the organic fertilizer equipment are transported to the finished product warehouse by bucket elevator. Granular materials can be weighed quantitatively and packed by automatic packing scale
A complete set of organic fertilizer granulation production line process: raw material selection, drying and sterilization, fermentation, crushing, stirring, granulation, drying, cooling, coating, screening, metering and sealing, product storage.
The complete set of fertilizer production equipment is mainly composed of fermentation system, drying system, deodorization and dust removal system, crushing system, batching system, mixing system, granulation system and finished product packaging system. The fermentation system includes: feed conveying, which is composed of machine, biological deodorant, mixer, special car polishing machine, oxygen supply system and automatic control system.
1. After the second fermentation to produce organic fertilizer according to the above steps, pile up the organic fertilizer for the second time for fermentation, and then reduce the temperature to 40 ℃ for about 15-20 days. When making organic fertilizer, we also need to use fermentation composting machine in the organic fertilizer production line. Bacterial agents with the functions of phosphorus, potassium, nitrogen fixation and underground pest control were evenly added to the fermented organic fertilizer in proportion of 1:500.
2. The standard of bio organic fertilizer can be reached within 7 days after adding functional bacteria and fermented organic fertilizer to the compost.
3. Screening and storing the fermented bio organic fertilizer.
4. After pelleting, the functional pure biological organic fertilizer will be pelleted successfully. According to the different raw materials, we choose granulator, disc granulator and roller granulator, which can also be used in the production process of NPK fertilizer to produce NPK and compound fertilizer.
5. The moisture content of the granules made only by drying, cooling and packaging is relatively high, so it is necessary to dry the moisture to less than 20% of the standard of organic fertilizer. When choosing dryer, bio organic fertilizer should be chosen. At low temperature (below 80 ℃), dry organic fertilizer particles should be packaged directly after cooling in cooler.
At present, the growth of agricultural production generally depends on chemical fertilizer. On the one hand, it will cause environmental pollution. In fact, the non-point source pollution in rural areas is very serious, which has become a problem. On the other hand, it will affect the quality of agricultural products.
Therefore, people gradually realize that when using chemical fertilizer, we must increase the proportion of organic fertilizer, especially for vegetables, fruits, tobacco and other economic crops. The use of biological fertilizer can not only increase yield, but also improve quality and protect crops. Ecological environment, extensive use of municipal waste, sludge, livestock manure, orange and other waste.
