In short, building an organic fertilizer production line requires many procedures and permits, and you also need to pay attention to issues and precautions in terms of technology, quality, environmental protection, and safety.

Only with comprehensive consideration and careful implementation can we build a high-quality, high-efficiency, environmentally friendly and safe organic fertilizer production line and contribute to sustainable agricultural development and environmental protection.

Generally speaking, for small-scale new organic fertilizer production lines, it is appropriate to have an annual output of 10,000 tons (1.5 tons/hour), 20,000 tons (3 tons/hour), or 30,000 tons (4.5 tons/hour). Medium-sized factories have an annual output is 50,000-100,000 tons, and large factories have an annual output of 100,000-300,000 tons.

There are many raw materials that can be used to process organic fertilizers, which can be divided into the following categories:

• Agricultural waste: such as straw, soybean meal, cotton meal, sugar cane, sawdust, etc.
• Livestock and poultry manure: such as chicken manure, cow manure, sheep manure, horse manure, rabbit manure, donkey manure, duck manure, etc.;
• Industrial waste: such as distiller’s grains, vinegar grains, mushroom residues, kelp residues, phosphorus citric acid residues, cassava residues, furfural residues, amino acid humic acid, oil residues, shell powder, peanut shell powder, etc.;
• Domestic waste: such as kitchen waste;
• Urban sludge: such as river sludge, sewer sludge, etc.
• Biogas slurry and biogas residue: The utilization of biogas slurry has many functions such as fertilizing fields and improving soil, preventing diseases and pests, and increasing yields.

1. Raw material:

The raw material is domestic waste, which mainly refers to solid waste generated from daily life or activities that provide services for daily life. Including discarded biological products, biological waste, spoiled food, solid particles, garbage, slag, etc.

Benefits of processing municipal solid waste bio-organic fertilizer:

Using municipal solid waste as raw material, it is fermented, turned and processed into bio-organic fertilizer particles. Microorganisms present in the garbage are used to cause biochemical reactions in organic matter to generate a substance similar to humus soil, which can be used as fertilizer and soil improvement. Treating garbage and sludge together or composting garbage and manure can not only reduce environmental pollution, but also improve fertilizer efficiency.

The following takes the design of a 5t/h municipal solid waste bio-organic fertilizer production line that RICHI has done as an example.

2. Process design

The 5T/H urban domestic waste bio-organic fertilizer production line refers to mixing domestic waste with some animal manure, straw and other organic matter, performing compost fermentation, drying and pre-treatment, and then enters the processing workshop for crushing, mixing, granulating, cooling, and packaging After processing in the section, bio-organic fertilizer is made.

Cow dung can be made into high-quality organic fertilizer products after fermentation. Cow manure contains 14.5% organic matter, 0.30-0.45% nitrogen, 0.15-0.25% phosphorus, and 0.10-0.15% potassium. Cow manure organic fertilizer is a cold fertilizer with lower organic matter and nutrient content among various livestock. It has fine texture, slow decomposition and low calorific value. It is a slow-acting fertilizer and is suitable for use as base fertilizer.

Pig manure contains 15% organic matter, 0.5% nitrogen, 0.5-0.6% phosphorus, and 0.35-0.45% potassium. Because it contains more nitrogen, the ratio of carbon to nitrogen is small, about 14:1. It is generally easily decomposed by microorganisms and releases nutrients that can be absorbed and utilized by crops. Pig manure contains the highest humus, the largest amount of cationic substitution, and the strongest fertility retention capacity.

However, it contains more water and has fewer cellulolytic bacteria. Mixing a small amount of horse manure and applying it to inoculate cellulolytic bacteria can greatly increase the fertilizer efficiency.

Below, RICHI will enumerate for you a design plan for a 6-ton pig manure organic fertilizer production line that we have made. We hope it will be helpful to you.

Sheep manure contains 24-27% organic matter, 0.7-0.8% nitrogen, 0.45-0.6% phosphorus, and 0.4-0.5% potassium.

Sheep are ruminants, but they rarely drink water, so their feces are dry and fine, and the amount of feces excreted is also very small. Sheep manure is relatively rich in nutrients. It contains both effective nutrients that are easily decomposed and can be absorbed and utilized by crops, and slow-acting nutrients that are not easily decomposed. It is a good fertilizer that combines fast and slow fertilizer effects.

Chicken manure bio-organic fertilizer refers to using chicken manure as the main raw material, mixed with some other organic matter, fermented, thrown, pre-treated, and finally granulated to become bio-organic fertilizer.

After fermentation, chicken manure is a relatively high-quality organic fertilizer. The nutrient content of chicken manure is very rich. It contains a large amount of organic matter and a high content of three elements of nutrients. The organic matter content is 25.5%, nitrogen is 1.63%, and phosphorus is 1.63%. It contains 1.54% potassium, 0.85% potassium, and 11% carbohydrates, so chicken manure is an important organic fertilizer.

Generally speaking, to process 5t/h chicken manure organic fertilizer, the process flow of the organic fertilizer production line is usually: fermentation and throwing section → pretreatment section → crushing section → mixing section → granulation and packaging section

1. Fermentation and turning section:
   For an aerobic fermentation, pile the mixed ingredients into a strip with a width of 1.5 meters to 2 meters and a height of 0.8 meters to 1.2 meters and a length of no less than 3 meters.
   During the fermentation process, pay attention to proper oxygen supply and turning the pile (the temperature rises to 75°C or above), the temperature should be controlled at around 65°C. Too high a temperature will affect nutrients. It takes 2 days to heat up, 3 days to become odorless, 7 days to become loose, 9 days to become fragrant, and 10 days to become fertilized.
   The secondary fermentation is the so-called post-aging stage, and can also be called secondary fermentation. After 7 days, the material can be decomposed and enter the post-aging stage. Then enter the pre-treatment and workshop granulation stage.
2. Pretreatment section:
   Chicken manure bio-organic fertilizer pre-treatment section: The fermented chicken manure is fermented and stored for 7 days before being crushed, and the fermented organic fertilizer raw materials are crushed, screened and dried.
3. Crushing section:
   In the crushing section of chicken manure bio-organic fertilizer, the dried materials must be sent to the crusher for crushing through conveying equipment. An iron removal device is equipped before entering the crusher.
4. Mixed processing section:
   Through the small material adding hopper, bacteria and raw materials can be added and mixed in the mixer. After mixing evenly, it enters the next section.
5. Granulation and packaging section:
   The chicken manure bio-organic fertilizer is evenly fed by the granulator feeding auger in the granulation section for continuous granulation by the granulator. The granulated granules enter the cooler for cooling. The cooled finished granules are automatically weighed and packaged, transported to the warehouse. Chicken manure bio-organic fertilizer uses a packaging scale in the packaging section.
   According to the customer’s local sales needs, a suitable packaging scale is selected to facilitate customers to sell the product. There are usually two specifications: small bags and ton bags.
   The packaging specifications of the small bag packaging scale are: 20-50kg/ Packaging specifications for bags and ton bags are: 500-1000kg/bag. The packaging scale has a high degree of automation and high packaging accuracy. The weighing system uses sensor measurement, which has high sensitivity and strong anti-interference ability.

The production of organic fertilizer is a project of recycling agricultural waste. Organic fertilizer production enterprises can be large or small, and there are no standardization requirements. Generally speaking, the planning layout of a 10-20 t/h large-scale organic fertilizer pellet plant includes the following partitions:

1) Factory gate and side door

The factory gate is the channel for company business transactions and finished product sales. The side door is the entrance channel for stinky raw materials such as feces. The side door is usually close to the fermentation workshop and raw material warehouse, in an inconspicuous location in the factory area.

2) Staff living area

The place where employees live, stay, relax and have fun. Staff living areas are generally far away from production areas. Vegetables, flowers, trees, etc. can be planted in the living area, which is pleasing to the eye.

3) Equipment storage area

Production workshop equipment layout

4) Raw material warehouse

5) Fermentation workshop

6) Semi-finished product storage area

Semi-finished products here refer to the area where the raw materials are temporarily accumulated and stored while waiting for processing after harmless fermentation.

7) Processing workshop

8) Finished product warehouse

What needs to be mentioned is that the raw material warehouse, fermentation workshop, semi-finished product storage area, and finished product warehouse in the processing workshop should be closely connected, which can greatly improve the work efficiency of the enterprise.

9) Office area

The office area should be set up near the living area to facilitate work and rest.

10) Planting demonstration area

The ecological formula fertilizer produced by the company itself can be tested in its own test field to understand the application effect of the fertilizer in real time.

Organic fertilizer is a kind of fertilizer made from natural organic matter as the main raw material. It has the advantages of environmental protection, safety and high efficiency. As people have higher and higher requirements for the quality of agricultural products, the demand for organic fertilizers is also increasing. In order to meet market demand, it is imperative to build a modern organic fertilizer production line.

Yes, we can provide the design and manufacturing of digestate organic fertilizer granule production line.

Biogas residue organic fertilizer is the residue after crop straw, grass, livestock and poultry manure, etc. are fermented by microorganisms to produce biogas in a biogas tank. Rich in organic matter and essential nutrients. Biogas ferments slowly, consumes less organic matter, and loses less nitrogen, phosphorus, and potassium. The nitrogen recovery rate reaches 95% and the potassium recovery rate is over 90%.

About 2Kg of functional bacteria are added to the biogas water and then used as flush fertilizer for dry land top dressing; the residue fertilizer is used as paddy field base fertilizer. If it is used as dry land base fertilizer, it should be re-soiled after application. After the biogas fertilizer leaves the pond, it should be fermented by microorganisms for about 12 days before use. Stirring tools, weighing equipment, conveying equipment, etc. required during production.

Processing process of organic fertilizer production line:

1. Preparation

• (1) Biogas residue: Because there are two biogas production methods in China, dry and wet, the moisture content of biogas residue is usually around 40%-70%.
• (2) Accessories: Accessories with a moisture content of no more than 10% (such as straw powder, rice bran, peanut shell powder, etc.) are mainly used to adjust the air permeability of the biogas residue during fermentation. If the air permeability of the biogas residue is good, it may not be added.
• (3) Biological fermentation bacteria: Use the weighed bacteria and auxiliary materials and mix them evenly in a ratio of 1:10 (the purpose is just to expand the volume of the bacteria so that it can be spread evenly on the biogas residue), and then add the required biological bacteria Weigh and increase the processing digestate at a ratio of 1:10,000 (one kilogram treats ten tons).

2.Production process design

• (1) If the moisture content of the biogas residue is above 70%, it can be mixed with the auxiliary materials in a weight ratio of 3:1, add 1% quicklime and stir, then add the expanded volume of microbial agent into the biogas residue, stir and stack evenly That’s it.
• (2) The moisture content of the stirred fermentation material should be controlled at about 60% (grip it gently with your hands to form a ball, and loosen it to make three or five cracks. At least make sure that you hold it firmly with your hands so that no water drips from between your fingers).
• (3) Stack the stirred fermentation materials with a height of about 1.2m, a width of about 2m, and no limit to the length. ​
• (4) After fermentation for 24-48 hours, the temperature can reach above 55℃, and the deodorizing effect can be achieved three days after the temperature rises.
• (5) After stacking and fermenting for 15-20 days, it can be used as bio-organic fertilizer.

At present, medicinal residue organic fertilizer is very suitable for countries such as China and South Korea that use traditional Chinese medicinal materials. Especially China. Because China is a big country in traditional Chinese medicine and produces more than a thousand varieties of traditional Chinese medicine. Tens of thousands of tons of dried Chinese herbal medicine are used in production every year, and the extracted Chinese medicine residue accounts for more than 80% of the total.

A large amount of Chinese medicine residue is almost poured into the garbage dump, which wastes resources, pollutes the environment, and occupies a large area. land. Most of the organic matter of traditional Chinese medicine residues is suitable for organic fertilizer production, so any traditional Chinese medicine residues can be used as raw materials for organic fertilizer production, turning waste into treasure.

The production method of medicinal residue organic fertilizer, the steps are as follows:

1. Crushing of raw materials: crush the dregs produced during production into 10 to 50 meshes through a pulverizer;

3. High-temperature equipment fermentation: Put the mixed materials in step 2 into the high-temperature fermentation tank, maintain the temperature at 60-90°C, and ferment for 2-15 hours to complete the fermentation;
4. Aging: Place the fermented material in step 3 in the aging room, keep the temperature at 60-70°C under ventilation, and age. Secondary fermentation will be performed during the aging process, which will last for 3 to 6 days;
5. Re-batching: Mix the aged materials in step 4 with nitrogen, phosphorus and potassium in a mixer according to 25~40:30~45:10~20:10~20, then put them into a grinder and grind them for 50~ 100 mesh;
6. Granulation: Put the raw materials crushed in step 5 into the fertilizer pellets processing machine, and granulate at a temperature of 50-60°C, keeping the moisture content of the material at 8-15%;
7. Drying: In the fertilizer dryer, maintain ventilation, control the temperature to 100-120°C, dry for 20-40 minutes, and the material moisture is 3-5%;
8. Cooling: Put the dried materials in step 7 into the cooling machine, and cool to room temperature under ventilation conditions;
9. Finished product: Screen the cooled material in step 8 through a screening machine to keep the particles between 1 and 4.5mm, and then package it.

The equipment required for the medicated residue organic fertilizer production line includes: fermentation compost turner, pulverizer, horizontal mixer, organic fertilizer granulator, drum dryer, cooler, screening machine, automatic quantitative packaging machine, belt conveyor, etc.

With the rapid development of social economy and the acceleration of urbanization, the discharge of industrial wastewater and domestic sewage is increasing, and the production of sewage sludge has also increased sharply.
