fertilizer production line

The agricultural solid waste resource utilization project adopts a land use model, establishes an organic fertilizer factory, uses livestock and poultry manure such as chickens, pigs, cows, sheep, and crop straw process materials, applies biological fermentation technology, and scientifically processes (biological fermentation, high-temperature sterilization, deodorization, drying) to produce environmentally friendly and efficient organic fertilizers with excellent quality and stable fertilizer efficiency, in order to achieve efficient resource utilization of livestock and poultry waste, and achieve a win-win situation of livestock and poultry breeding benefits and environmental protection ecological benefits.

The granulation process flow of organic biological fertilizer production line

The entire process can be simply divided into three processes: pre-treatment, primary fermentation, and post-treatment.

Pre treatment: After the compost raw materials are transported to the yard, they are weighed by a scale and sent to the mixing and stirring device. Organic wastewater from production and domestic use cannot be mixed in the factory, and must be treated with clean water.

Then add organic biological fermentation compound bacteria (1-2 kg per ton of raw material), and roughly adjust the moisture content of organic fertilizer according to the raw material composition (chicken manure: cassava residue or mushroom residue: straw=6:2:2) to 60% -65%, with a carbon to nitrogen ratio of 20-30. After mixing, proceed to the next process.

When adding ingredients, the brown sugar must be dissolved in water first, and then organic fertilizer fermentation bacteria should be added and stirred thoroughly. Then, the diluent should be evenly sprinkled on the raw materials and thoroughly stirred with a fertilizer mixer.

Attention: The composting raw materials should be treated several hours in advance, soaked in water, and the water used to dilute the biological fermentation bacteria should be considered as drinking water without disinfectants (such as bleach powder).

Primary fermentation: The mixed raw materials are sent to the primary fermentation workshop using a loader to form a fermentation pile. At the same time, the pile is flipped for about 2 days and supplemented with water and nutrients. The fermentation temperature is controlled at 50 ℃ to 65 ℃ (hot to the touch) for aerobic fermentation. The fermentation cycle for this project is 8 days, with one tank of raw materials entering and one tank of semi-finished products exiting each day. After the fermented semi-finished products are discharged, they are ready to enter the next process.

Post processing: Further screen the compost product, and the screened material is processed according to the moisture content. After sieving and granulating, the material is sent to a fertilizer dryer for drying. Various additives are added in proportion, stirred and mixed to produce finished products, which are packaged and stored for sale. The screened material is returned to the crushing process for reuse.

Functional characteristics of pig manure tank type tipping machine:

The pig manure tank type dumping machine is a dumping equipment that operates on a pre laid track. Therefore, the pig manure tank type tipping machine must be used as a fermentation tank, and the fermentation tank must be laid with tracks.

It is mainly used for the fermentation and flipping of livestock and poultry manure, sludge waste, biogas residue cake, and organic waste. It is mainly used for the composting and fermentation of manure in organic fertilizer production plants, compound fertilizer plants, garbage sludge plants, horticultural fields, and mushroom plantations, as well as various breeding farms.

The difference between pig manure tank type tipping machine and self-propelled tipping machine is that it operates on a track and can flip the materials in the fermentation tank back and forth. Generally, when equipped with a displacement car, it can be used in multiple tanks for aerobic fermentation. It can be used in conjunction with solar fermentation chambers, fermentation tanks, and displacement cars. It has high efficiency, smooth operation, durability, and even flipping and throwing. Implement manual and semi-automatic control functions through the control cabinet.

The pig manure tank type tipping machine is used for flipping and throwing materials in the fermentation tank. Equipped with a displacement vehicle, it can achieve the function of one machine with multiple slots, which can greatly save equipment investment.

In general, the overturning depth should be 1.2 meters, the overturning width should be 6 meters, and the track should be equipped with angle iron below 2 meters and light rail runway above 2 meters.

The pig manure track type turner is suitable for zero emission projects in pig farms. Generally, the pig manure track type turner requires a groove depth of 1.2 meters and a material stacking of 1 meter for flipping and throwing. Standard equipment below 2 meters does not include a shifting car (customizable), and the equipment is equipped with a walking frequency converter and a winding device. There is currently no limit switch, and the equipment needs to be manually operated to move forward and backward. The advantage of pig manure tank stacker over self-propelled tipping machine is that it has a higher processing capacity, but it has requirements for the working environment.

From the perspective of a cattle farm, cow manure is a form of waste. Can cow manure be further developed and fully utilized? It has become a concern for people. But currently, this issue is no longer a difficult one. With the emergence of various advocacy and encouragement policies by the country and various regions to develop the organic fertilizer industry, the timing for the large-scale and industrialized development of cow manure commercial organic fertilizer has become more mature.

What organic fertilizer equipment is needed to make cow manure into organic fertilizer?

Step 1: Tank fermentation equipment

Collect cow manure and urine, mix them with hay and rotten silage to make compost, and let it ferment. Using an organic fertilizer composting machine to fully ferment cow manure during fermentation can only be achieved through timely and uniform composting. Some places are very dry now, while others are very wet, which can affect the quality of fermentation.

Step 2: Material crushing equipment

Wet material crusher is a crushing equipment that crushes high humidity, multi fiber substances. Utilizing high-speed rotating blades to crush fibers with good particle size and high energy. Semi wet material crushers are commonly used in the production and processing of organic fertilizers, and have good effects on crushing raw materials such as chicken manure and humic acid sodium.

Step 3: Mixing and stirring equipment

The organic fertilizer mixer has a fast mixing speed and good uniformity, and can mix viscous materials with 30% added liquid. During operation, there are two opposite rotating rotor blades stirred in the middle. Due to the multiple special angles of the blade, regardless of the shape of the material. What is the size and density. They can mix quickly and effectively. Adopting a lower door for fast unloading speed and minimal residue.

The harmless treatment of feces is achieved by using scientific methods to kill or remove pathogenic microorganisms and parasitic eggs in the organic fertilizer production line of cow manure in the breeding farm. At the same time, the fertilizer efficiency of the feces can be preserved, and the treated feces can meet the requirements of harmless hygiene standards.

Organic fertilizer production line or npk fertilizer production line, the main equipment of general processing technology includes fermentation equipment, mixer, overturning equipment, belt conveying equipment, cylindrical screen, pulverizer, granulator (roller granulator, rotary drum granulator, stirring tooth granulator, disc granulator), etc, in the early stage of granulation and after the granular fertilizer is screened, it needs to be pulverized and granulated again, so what should be paid attention to when purchasing an organic fertilizer pulverizer?

When buying an organic fertilizer grinder, pay attention to the following points.

1. Model and type of organic fertilizer grinder. Pay attention to the model size of the machine. The production capacity of different models and the size of the machine are different. According to your own needs, you must recognize the specifications of the machine when purchasing.

2. The quality of the organic fertilizer crusher must meet the specified standards.Choose a good organic fertilizer pulverizer to buy an organic fertilizer pulverizer. If it is not too far from the manufacturer or not too far from the manufacturer, check its processing capacity. General manufacturers can test the machine on the spot. You can also bring some of your own raw materials to the manufacturer to test the machine to see if it is the equipment you want, the processing capacity and the effect of use.

3. The price of organic fertilizer crusher. Many customers tend to ignore this problem when purchasing organic fertilizer grinders, so they can shop around. Of course, too cheap is not necessarily good equipment, too expensive also has a tendency to violence.

4. Professional manufacturer of organic fertilizer crusher. So how to choose a good manufacturer? Of course, it is a professional manufacturer of organic fertilizer pulverizers, with good quality and service system. Choosing a good manufacturer can not only allow you to process organic fertilizers smoothly, but also make you satisfied with the after-sales service of organic fertilizer pulverizers, and immediately solve some problems in your processing. 

During the production of powdered organic fertilizer, it mainly adsorbs dust and floating particles floating in the air. In the harmless treatment of livestock and poultry manure, aerobic stack fermentation is generally used. That is to say, in general stack fermentation, it is important to avoid wind and rain during fermentation to reduce organic matter. Therefore, before fermentation, it is necessary to build a rain shelter and stack the fermentation tank.

The following is the process flow of a small cow manure powder organic fertilizer production line:

1. Raw material ratio per ton: 500kg of cow manure+300kg of pig manure+200kg of bacterial residue+50g of bacterial species (cow manure and pig manure can also be replaced by other animal manure). Auxiliary materials: When the humidity of animal manure is high, appropriate materials with low moisture content such as straw, rice husk, and cake can be added to reduce the moisture content of fermentation materials.

2. Stacking: According to the above raw material ratio, stack as needed. The length of the stack is unlimited, with a width of 2 meters and a height of about 1 meter. When stacking materials, it is necessary to stack them layer by layer evenly. Select the appropriate width of the fertilizer flipper based on the amount of fecal treatment each time.

3. Adding bacterial strains: Expand the bacterial strains and residue in a 1:5 ratio (the purpose of doing this is to dilute the bacterial strains and spread them evenly. For example, using 1kg of bacterial strains with 5kg of wheat bran or rice husk powder is acceptable). Generally, 1kg of bacterial strains can ferment 10-20 tons of feces and straw. In cases of high fermentation capacity, a dual axis horizontal mixer can be used to evenly mix and sprinkle on the surface of the pile according to the number of piles.

4. Flipping fermentation: Use a slot type flipping machine to flip the stack. When the temperature rises to above 55 ℃, flip the stack every 1-2 days. After 10-15 days of fermentation at 55 ℃, fold the stack. (The purpose of flipping the pile is to evaporate water, allow oxygen to enter the interior of the pile, and allow bacteria to quickly reproduce and ferment inside the pile.)

5. Crushing: Fermented materials cannot be directly sold as commodities because long-term stacking can cause clumping and other phenomena. At this point, the remaining large pieces of material need to be finely crushed by a high humidity material crusher to obtain powdered organic fertilizer. (In the early stage of fermentation, in order to accelerate the fermentation process, auxiliary materials can be added to the fertilizer crusher for crushing.)

6. Screening: In order to improve the appearance, the powdered organic fertilizer is re screened to obtain a uniform and consistent powdered material before packaging. After following the above steps, the pure powdered organic fertilizer is sieved by the drum screening machine.

7. Packaging: The powdered organic fertilizer can only be directly stored and sold after being packaged on an automatic packaging scale.

1. The water-soluble fertilizer production line is divided into multiple system parts, namely: feeding system, batching system, crushing system, mixing system, packaging system, palletizing system, etc.

2. Technical solution one for water-soluble fertilizer production line:

The production line adopts a three-dimensional structure layout, with a total platform height of 5 meters. The raw material packages are lifted to the feeding platform through a freight elevator, and the materials are manually prepared before being put into the mixer. The mixer is configured with a volume of 1m3 and an effective volume of 0.7m3. Each mixing is about 400kg, and the general mixing time is about 3-4 minutes depending on the material situation.

3. Comparison of advantages and disadvantages of fully automatic production equipment for water-soluble fertilizers:

The mixing system adopts a double screw belt mixer, and 99% of the materials can be unloaded except for a small amount of material stored at the mixing bottom. The crusher is installed above the ingredient bin, and the platform is used for feeding. The granular urea is transported to the crusher through vacuum feeding, which saves time and effort.

Configuration of various water-soluble fertilizer production lines:

Powder water-soluble fertilizer production line: material elevator, feeding port, crusher, mixer, packaging machine, sealing machine;

Particle blending fertilizer production line: material elevator, feeding port, drum mixer, packaging machine, sealing machine;

Liquid water-soluble fertilizer production line: material elevator, feeding port, heating reaction kettle, emulsion filter, filling machine, capping machine.

For early-stage entrepreneurs or friends with low budgets, the target output is not high, and semi-automatic production lines are sufficient. First, open up the market and gradually expand later.

Common granulators include double roller granulator, npk granulator, disc granulator machine, tooth stirring granulator, rotary drum granulator, etc. How much do you know about roller granulator, it is suitable for What raw materials are used, what are the advantages, and what should be paid attention to when using them?

The granulation raw materials of the double roller granulator can be used for the granulation of organic fertilizers such as livestock manure, kitchen waste, industrial waste, straw leaves, trough residues, oil cakes, etc, compound fertilizer granulation such as npk manufacturing process, chemical industry , granulation of feed, etc.

Advantages of double roller granulator：

1. Low energy consumption and energy saving road roller extrusion granulation is a kind of material granulation at room temperature. Compared with other methods, no drying measures such as fuel and gas are required.

2. Steam granulation is a commonly used production method of binder-free compound fertilizer in my country. Dry granulation does not require another additive, and only needs to use the intermolecular force of the material itself, simplifying the process and reducing energy consumption.

3. The low investment is due to the saving of the drying process, the low rate of return (about 15% of the total feed of the extruder), the simple process flow and the low investment.

4. The consumption capacity of extrusion granulation is electricity, and the environmental protection has no three wastes discharge, which is in line with the national basic environmental protection policy and the environmental protection development strategy of Taiwan enterprises.

Precautions for operation of double roller granulator：

1. Before starting the roller granulator, please check whether there is any debris in the machine.

2. Check whether the machine on the roller granulator is normal.

3. It is strictly forbidden to start the roller granulator under load.

4. After the drum granulator is started, check whether the rotation direction is correct. If it is reverse rotation, please stop adjusting immediately to ensure stable rotation and no noise. Then start production.

Process flow of organic fertilizer production line for manure treatment in livestock and poultry farms

In livestock and poultry farms, manure treatment is a crucial step, and the production of organic fertilizer is one of the important methods for converting these manure into valuable resources. The process flow is mainly divided into four steps: collection, separation, composting, and fermentation.

The first stage is the collection phase, where livestock and poultry manure is effectively collected and preliminarily separated. It is possible to separate livestock and poultry manure from urine through a centralized collection and separation system to reduce the generation of ammonia and odor, and improve subsequent treatment efficiency.

Then comes the composting stage, where the separated animal manure is sealed and stored, and organic waste is properly organized and stacked, supplemented by ventilation equipment to control temperature, humidity, and oxygen supply, accelerating the decomposition process of organic matter. During this process, it is important to maintain appropriate humidity and ventilation to avoid the generation of odors and harmful gases.

Finally, in the fermentation stage, after the completion of composting, the compost is subjected to secondary composting fermentation to further enhance the stability and efficiency of the fertilizer. This process requires attention to reasonable moisture control and temperature regulation to ensure the full decomposition of organic matter and the killing of harmful microorganisms.

Organic fertilizer provides organic matter to the soil, thereby providing the necessary nutrients for plants and helping to establish a healthy soil system, rather than destroying it. Therefore, organic fertilizers contain huge business opportunities, and with the gradual restrictions and prohibitions on the use of fertilizers by most countries and relevant departments, the production of organic fertilizers will become a huge business opportunity.

Most organic raw materials can be fermented into organic compost. In fact, after crushing and screening, organic fertilizer compost becomes high-quality and saleable powdered organic fertilizer.
