Precautions for using fertilizer processed by organic fertilizer production line

fertilizer granulator Mar 4, 2023

Produced by the organic fertilizer granulator machine is comprehensive in nutrition, contains nitrogen, phosphorus, potassium and trace elements, has long-lasting fertilizer effect, can improve the soil environment, and the application of organic fertilizer has an important effect on crop yield and quality. However, improper selection and use of organic fertilizers can also cause crop damage and yield reduction. Please pay attention to the following points when selecting and using organic fertilizers:

1. Pay attention to choose high-quality organic fertilizer
 

High-quality organic fertilizers are the basis for high-quality and high-yield crops such as vegetables and fruit trees. The quality of organic fertilizers used by farmers is uneven, and some are even mixed with urban sludge and domestic garbage. Even some of the chicken manures bought were mixed with mud, or were mixed with caustic soda by some unscrupulous traders (to increase the volume). After applying these inferior organic fertilizers to the soil, the effect can be expected. Therefore, high-quality organic fertilizers must be used in production. It is best to use regular large-scale factories when choosing commercial organic fertilizers.

2.Make sure to rot before applying

The current composting process still lacks the necessary maturity judgment standards and detection methods. In addition, the sources of organic fertilizers are complex and diverse. Therefore, for chicken manure and cow dung, which often carry germs, insect eggs and weed seeds, they are directly applied or piled. Incompletely roasted rot will adversely affect crop growth.

3.Strictly control the amount of fertilization

In general, organic fertilizer has a large volume and low nutrient content. It needs a large amount of application to meet the needs of crops, but not as much as possible. For example, it is advisable to apply 15-20 cubic meters of pure chicken manure and 35-40 cubic meters of decomposed soil and mixed fertilizer per acre per season. For eggplants and vegetables, the amount of fertilizer required is large, and the upper limit may be used; for leafy vegetables, the amount of fertilizer required is slightly smaller, and the lower limit may be used.

4.Organic and inorganic application

Organic fertilizers are full of nutrients, slow to release, and have long fertilizer effects. When crops need high fertilizer growth, they are often in short supply; while inorganic fertilizers are generally relatively simple in content, easily decomposed and absorbed by crops, but have insufficient stamina. Therefore, organic fertilizer and inorganic fertilizer must complement each other to complement each other.

5.Mainly Shiji and Shenshi

Organic fertilizers have long-lasting effects and slow nutrient release, and are generally applied as base fertilizers. In deep ploughing, the application of organic fertilizer is beneficial to the integration of soil and fertilizer and promotes the formation of soil aggregate structure, which can effectively improve the physical and chemical properties of soil and increase soil permeability.

6.Good effect with the application of biological fertilizer

Whether organic fertilizer is applied basally or flushed, it is best to use bio-fertilizer. The biological bacteria in the biological fertilizer can accelerate the decomposition of the organic matter in the organic fertilizer, making it more conducive to crop absorption, and at the same time can decompose and transform some harmful substances in the organic fertilizer to avoid damage to the crop. Generally, when organic fertilizer is applied at the base, 150-200kg of bio-fertilizer can be applied per acre, and 20-25kg per acre can be applied for topdressing.

Technology and equipment of fertilizer production line using straw to process organic fertilizer

fertilizer granulator Mar 1, 2023

Process and equipment for processing commercial organic fertilizer using crop straw

(1) Production and processing of plant residues and refined organic fertilizer manufacturing process

Using plant residues to refine organic fertilizers is the simplest method for plant organic fertilizers manufacturing process. First, the plant residues are crushed into materials less than 3 cm with a semi-dry grinder, and then according to the nutritional requirements of fermenting microorganisms (generally inoculated with high temperature bacteria), a variety of plant residues are compounded into culture materials, inoculated with microorganisms, and passed through Auxiliary heating can produce a lot of heat within 4-5 days of fermentation, so that a large amount of water in the raw materials can be evaporated, quickly deodorized, quickly dehydrated, low energy consumption, low production cost and economic. However, this organic fertilizer has a low degree of fermentation and maturity, and once it is wet with water, it can easily cause rancidity or worms.

(2) Production and processing of bio-organic fertilizer after fermentation of plant residues

Bio-organic fertilizer refers to organic materials formed by specific functional micro-bovines (such as nitrogen-fixing bacteria, phosphate-solving bacteria, potassium-releasing bacteria, etc.) and harmlessly processed and decomposed animal and plant residues (such as livestock and poultry manure, crop straws, etc.) A compound type of fertilizer with microbial fertilizer and organic fertilizer effect. The essential feature of bio-organic fertilizer is that it contains higher organic matter and microorganisms with specific work and specific functions. The contained microorganisms exhibit certain fertilizer effects, such as improving soil fertility, fixing nitrogen in the air, assisting crops to absorb nutrients, activating insoluble plant nutrients in the soil for crop absorption, etc., or producing multiple active substances or resisting pathogenic bacteria Substances have a good stimulating and regulating effect on crop growth, reduce or reduce the occurrence of crop diseases and insect pests, and improve the quality of agricultural products.

Compared with ordinary organic fertilizers, the production technology content of bio-organic fertilizers is relatively high. In addition to the addition of biological fungi that promote the decomposition and decomposition of organic materials during the rot process, to achieve the purpose of directional rot and deodorization, it is also added to the product Microorganisms with specific functions to enhance the effect of products. To produce this type of organic fertilizer, the first thing is to have the technology and ability to produce specific functional microorganisms. After crushing a variety of plant residues, select a compound fermentation microorganism that is basically consistent with the biological characteristics of the existing specific microorganisms. According to the characteristics of the compound fermentation microorganisms, the crushed plant residues are compounded and a certain amount of inorganic compounds are added to make a fermentation culture material. , Adopting trough stacking fermentation method, flat-ground stacking fermentation method, fermentation tank fermentation method, closed warehouse fermentation method or tower fermentation method, etc., the decayed material basically achieves the harmlessness of the product, which is beneficial to the addition of functional bacteria during the post-processing Survive. In the post-processing of fermentation materials, it is usually added with functional bacterial agents for compounding and shaping; the product dosage form is mainly powder, and there are also granulation techniques. Most of them use disc granulation, drum granulation or extrusion granulation. less. : Granular products overcome the shortcomings of poor appearance and low level of powder products, improve the product’s commerciality, but also increase the production cost of the enterprise and have a certain impact on the survival of effective bacteria.

The characteristics of the roller granulator in the npk fertilizer production line

fertilizer granulator Mar 1, 2023

With the development of environmental protection and organic agriculture, the use of organic waste to produce organic fertilizer production line through bio-fermentation has been rapidly developed. And the disposal of organic waste has become harmless and resource-oriented. However, most of the biofertilizer project fermentation are a coarse powder or irregular small pieces, which is inconvenient to use and is particularly disadvantageous for large-area machine broadcasting. In this case, a new type organic fertilizer granulator machine came into being. It is used to granulate various organic substances after fermentation, breaking through the conventional organic granulation process.

The subject of the invention is method of PK and NPK fertilizer production line by feeding to the granulation process superphosphate slurry, so-called MSP slurry, together with MAP slurry or instead of MAP slurry, in amount to 100% by weight of P2O5 contained in fertilizer. Total participation of MAP and MSP slurry amounts from 5 to 80 % by weight of fertilizer. MSP slurry is a suspension containing mixture of mono- and dicalcium phosphates and calcium sulphate in saturated solution by above salts above mentioned and free phosphoric acid. MSP superphosphate slurry is obtained in the reaction between phosphate rock and mixture of phosphoric and sulfuric acids in mutual ratio: from 40 to 63% by weight of phosphate rock, from 37 to 60% by weight of mixture of phosphoric and sulfuric acids. The amounts of the acids are given as 100-percent acids.

Is it profitable to set up an organic fertilizer equipment and fertilizer processing plant in the countryside?

fertilizer granulator Mar 1, 2023

The demand for fertilizer is increasing, and the country is now focusing on the development of organic agriculture. Therefore, opening an organic fertilizer equipment factory is a good project.

In terms of production scale alone, the small-scale organic fertilizer processing plant is based on an annual output of 10000 tons to 30000 tons, which is also the most selected production line scale for investors who are new to the industry. As a production line, it is not composed of single equipment or 2-3 equipment. The complete set of equipment is composed of many kinds of equipment. Their type selection, specification and quantity directly affect the final price of the production line. That is to say, the price of the production line with the same output is not the same, even very different. Under the same output, the powdery production line is much cheaper than the granular production line, but the corresponding powdery finished organic fertilizer is not as expensive and profitable as the granular organic fertilizer.

Cost input of organic fertilizer equipment:

In the production process of organic fertilizer, raw material costs, transportation costs, labor costs, packaging costs, etc. need to be considered. If we cooperate with the farm, the farm will invest in the construction of greenhouses and fermentation tanks on the original site where the farm’s excrement is stacked, and the organic fertilizer manufacturer will invest in the organic fertilizer equipment to treat the excrement, which not only solves the problem that the farm owner’s excrement can not be treated, but also saves a part of the costs of the organic fertilizer production investor. The cooperation between the two parties through investment or compensation trade will reduce the investment or production costs.

Advantages and benefits of manure organic fertilizer production line

fertilizer granulator Mar 1, 2023

Considerations of organic fertilizer manufacturing process：

1. Determine the output of the organic fertilizer production line. For example, the number of tons produced per year, or the number of tons produced per hour, can determine the specifications of organic fertilizer production equipment.

2. Determine the shape of the particles. It is to choose what kind of granulator: powder, column, flat ball or standard garden. Commonly used granulation organic fertilizer equipment are: disc granulator, drum granulator, wet granulator, counter-roller extrusion granulator, flat die granulator, and ring film granulator. The selection of fertilizer granulator machine should be determined according to the preferences of the local fertilizer sales market. The particle shape is different, the production process of organic fertilizer is also different, and the price of organic fertilizer equipment is also different.


 

3. Determine the configuration level of the organic fertilizer equipment. The level of equipment configuration determines the price of the equipment, the amount of labor is different, and the ability of the equipment to operate stably is also different. Generally, those with high configuration should add some links, such as automatic batching device, automatic packaging device, automatic quantitative feeding device, cyclone dust removal and water dust removal.

4. Determine the type of fertilizer produced. It is a compound fertilizer equipment or an organic fertilizer equipment. For the same output, the organic fertilizer equipment generally takes into account the high moisture content and the strains are not resistant to high temperature. The model is generally larger than the compound fertilizer model. There are 4 types of general organic fertilizers, pure organic fertilizers, organic-inorganic compound fertilizers, biological organic fertilizers, and compound microbial fertilizers. Different types of organic fertilizers have different equipment.

5. Selection of fermentation turning and throwing machine: The general fermentation forms are: strip-stack fermentation, shallow-cao fermentation, deep-tank fermentation, tower fermentation and rotary drum fermentation. . Generally, it is more suitable to use shallow slot stacker. The advantages of the shallow tank stacker: it is more in line with the principle of aerobic fermentation, it is not easy to form anaerobic, the fermentation is full and complete, and the fermentation speed is fast.

6. Determining the level of environmental protection requirements: Where environmental protection requirements are low, heavy dedusting is generally sufficient, and investment in organic fertilizer equipment is low; where environmental protection requirements are high, heavy dedusting and water and ink dedusting are generally selected to meet national air emission quality standards.

Production line process of organic fertilizer fermentation using crop and animal manure

fertilizer granulator Mar 1, 2023

The organic fertilizer manufacturing process for crop straw and animal manure usually consists of pre-treatment, main fermentation, post-fermentation, post-treatment, compounding and other processes.

 
1. Pre-treatment

The main task is to remove non-fermented foreign matters such as sludge, metals, batteries, etc. in plant residues, crush plant residues, and adjust moisture and C / N value. Reasons for removing non-fermentation foreign bodies: reducing the volume of the fermentation chamber; removing the materials that affect the fermentation, such as metals and batteries, and reducing the chance of heavy metal pollution; removing the hard-to-crush materials such as plastic ropes, which is conducive to subsequent crushing and stirring Reasons for crushing to adjust the size of plant residues: usually crushing makes the moisture of the raw materials uniform to a certain extent, increases the specific surface area of ??the material, increases the area where the material contacts the microorganisms, 2 high 30 solution speed. Theoretically speaking, the finer the material, the better, but in order to ensure a certain gap of the material to ventilate to obtain oxygen, the range of 2 to 30 mm is generally better.

2. Main fermentation

It can be carried out in the open air or in the fermentation device, and oxygen can be supplied to the accumulation layer or the fermentation device by turning the pile or forced ventilation. The first is the decomposition of easily decomposable substances such as sugar and protein, producing CO2 and H20, and at the same time generating heat, which raises the fermentation temperature. In the initial stage of fermentation, the decomposition and fermentation of the substance relies on mesophilic bacteria (30-40 ℃ is the most suitable growth temperature). As the fermentation temperature rises, the high-temperature bacteria with the most suitable temperature of 45-65 ℃ replace the mesophilic bacteria. Various pathogens, insect eggs and weed seeds are killed. Generally, the period from when the temperature rises to when it starts to decrease is called the main fermentation stage, which is 3 to 10 days.

3. Post-processing

In the material after two fermentations, almost all of the organic matter has become finely crushed and deformed, and the amount has been reduced. Once again, a sorting process is performed to remove debris such as plastic, glass, ceramics, metal, small stones, etc. broken.

4. Deodorize

Some fermented products have an odor after the fermentation is finished, and deodorization treatment is necessary. Methods include chemical deodorant deodorization, alkali water and aqueous solution filtration, activated carbon, zeolite, special soil, etc. as adsorbent filtration.

5. Compound

According to the product formula requirements and the nutrient content of the material after fermentation, urea, phosphate fertilizer, and potassium fertilizer are added to the fermentation material to produce an organic-inorganic compound fertilizer, or microorganisms with specific functions are added to produce a biological organic fertilizer.

6. Inspection, packaging, storage

Test and analyze whether the nutrient content, maturity, moisture content, heavy metal content, pathogen content, organic matter content and other indicators meet the product requirements. Weighing, packaging and storage after meeting the requirements.

Is it expensive to process pig manure through organic fertilizer equipment?

fertilizer granulator Mar 1, 2023

Pig manure is a high-quality organic fertilizer processing material. How much pig manure can produce one ton of organic fertilizer depends on the water content in pig manure and the production method of pig manure organic fertilizer. The raw materials for processing pig manure and organic fertilizer in the organic fertilizer equipment processing plant are mostly purchased from the pig farm. The pig farm cleans up a large amount of pig manure, and generally uses water to flush the manure or a manure cleaner to clean the pig manure.

Cleaning up pig dung with water will lead to more water content in pig dung, and the water content will not increase with the dung cleaner. If the water content in pig dung reaches 50% – 60%, then about 2.5 tons of pig dung can produce one ton of finished organic fertilizer. The method to determine the water content in pig dung: knead it into a ball without dripping water, loosen it and disperse it, and loosen it with cracks. In this state, the following process steps can be performed.

Organic fertilizer equipment pig manure fermentation organic fertilizer method:

Prepare pig manure, straw and starter, and simply crush the straw. Then, mix the pig manure, straw and starter together, and use a mixer to fully stir evenly. The mixed pig dung is piled up, and the tank type tipping machine is used for tipping fermentation. Generally, it needs to be flipped once in the third and fourth days of fermentation. When the odor of the compost pile becomes small, grayish brown, covered with white hypha, and becomes loose, the pig manure organic fertilizer is successfully fermented.

Equipment required for processing cow manure organic fertilizer production line into fertilizer

fertilizer granulator Mar 1, 2023

Cow manure organic fertilizer production line is loved by many investors

The cow manure organic fertilizer manufacturing process is a complete set of organic fertilizer granulator machine for processing organic manure using cow manure as raw material. You can use a cow manure processor to first pump cow manure from the manure tank to the equipment through the mud pump, and the equipment can be dehydrated after treatment. Fertilizer granulator machine price is also very favorable.  About 90%, crops such as straw and rice bran (including N \ P \ K) can also be used as filler, and then sprinkled with biological strain agent, 1KG strain agent mixed with 20K and moved into the raw material, which can ferment 1 ton of raw material. Turn over once every 1-2 days, usually 7-10 days can be completely rotted.

 

The investment is small and the effect is fast. In recent years, the pollution of livestock and poultry manure and urine and the residues of livestock and poultry products have caused human health problems. Pollution from livestock farming has become a major source of pollution in rural areas of China. Such huge data of livestock production must be paid attention to, and if it is not handled well, it will cause serious pollution to the environment. For example, the lack of timely treatment of livestock and poultry manure can cause serious pollution to surface water, groundwater, soil and air. What’s more serious is that, for the convenience of transportation, the smaller households simply piled up the manure of the beef cattle next to the highway, and did not adopt a scientific storage method.

Due to negligence in management, wind and rain make the feces flow everywhere. Such a situation is not only unfavorable to animal epidemic prevention requirements, but will also have a certain impact on people’s living environment.

Equipment composition and operation principle of the whole set of organic fertilizer production line

fertilizer granulator Mar 1, 2023

The operation of a complete set of organic fertilizer manufacturing process is a little complicated. This equipment has many components, which have been improved a lot on the basis of traditional equipment. Now the scope of application is relatively wide.

What equipment is included in the complete organic fertilizer process? The first thing we need to know about this issue is the production process of organic fertilizer, which includes: fermentation → crushing → ingredients → stirring → granulation → shaping → drying → cooling → sieving → packaging. We take the most common organic fertilizer made from poultry manure as an example. The specific applications include fermentation stacker, semi-wet material crusher, double paddle mixer, organic fertilizer granulator, dryer, cooler, and screening Equipment, packaging scales.

 

The core equipment for making organic fertilizer is the organic fertilizer granulator and dryer. You need to choose the corresponding granulation equipment and drying equipment according to the different materials.
 

The organic fertilizer granulator is mainly composed of disc granulator and agitator granulator. The equipments chosen for the two are different due to different materials. The number of disc granulators is one type of spray granulation. The process and operation are very simple.

The compressed granules have a large water content, which increases part of the drying cost. The tooth stirring granulator is a new type of organic fertilizer granulation equipment developed by taking advantage of the shortcomings. It shields certain shortcomings, so that the materials are evenly distributed under the action of centrifugal force at the same time as the high-speed operation, the streamline is good and the density is high, and the molding rate of the difficult-to-bond materials is large, and the application range is wide.
