organic fertilizer production line

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.

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.

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.

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.

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.

Organic fertilizer manufacturing process has advantages in today’s national conditions, because the country advocates the concept of green environmental protection, so organic fertilizer manufacturing process still plays a relatively large role in production. Organic fertilizer is the use of waste that pollutes the environment to provide better organic fertilizer for agricultural production.

The material of organic fertilizer is manure or sludge. The application of organic fertilizer equipment and equipment generally needs to be dehydrated, dried, fermented, destroyed, and agitated. Then, according to the consequences of our requirements, stop the equipment. If it is required to make organic fertilizer powder, the basic technology of organic fertilizer equipment is dehydration, drying, fermentation, destruction, stirring, and packaging. After stirring, it can be packaged and stored.

If it is to make columnar granules, the basic process of organic fertilizer equipment is dehydration, drying, fermentation, destruction, mixing, granulation, cooling, packaging. Granulator, after granulation, the machine can be packaged or sold after cooling. It can also be bagged and stored after half an hour of artificial drying.

If spherical particles are required, the basic process of organic fertilizer equipment is dehydration, drying, fermentation, destruction, stirring, granulation, rolling, cooling, sieving, packaging, that is, to stop grinding and polishing of compressed columnar particles The pellets are rounded and then cooled and sieved to enter the packaging sequence.

Other material examples are based on practical materials combined with manure or sludge-type organic fertilizers. Equipped with fair and accurate organic fertilizer equipment, and then stopped according to the water content and fineness to stop the necessary treatment to properly suppress the formation of suitable particles.The goal of normalizing fertilizer efficiency. Fair and accurate selection of compound fertilizer equipment. In order to increase or decrease the reinvestment, when selecting organic fertilizer equipment, it is generally possible to make a conservative production estimate based on the model recommended by the manufacturer, so as to ensure that the intended purpose is completed under the customary form.

The equipment and equipment of organic fertilizer can effectively deal with the purification of inorganic wastes in livestock and poultry farming industries. He and inorganic food have laid the foundation of excellent quality, and the ecological situation has extremely obvious benefits. We have applied the process equipment and equipment of organic fertilizer and equipment, so that the organic fertilizer equipment and equipment can maximize the service for our production, work for our miracles, and add luster to our diligent chapter.
