Equipment and technology for building a small organic fertilizer production line

fertilizer granulator Dec 27, 2024

The small-scale organic fertilizer production line is either a powdery organic fertilizer production process line or a granular organic fertilizer production process line. Among them, the powdery organic fertilizer process line is a component of the granular organic fertilizer process line. Generally speaking, organic fertilizer production lines with an annual output of 20,000 tons and organic fertilizer production lines with an annual output of less than 20,000 tons are small-scale organic fertilizer production lines. According to the plans of most customers, the small-scale organic fertilizer production line basically has several major production lines of 5,000 tons, 10,000 tons, 15,000 tons, and 20,000 tons.

Since the powdered organic fertilizer production line is a component of the granular organic fertilizer production line, today we will use the granular organic fertilizer production line to describe in detail which organic fertilizer machine is required for the small-scale organic fertilizer production line process.

The process of the powdery organic fertilizer production line is clear. According to the fertilizer production process, the granular organic fertilizer production line is divided into crushing process, fermentation process, stirring and mixing process, granulating process, drying process, screening process, coating process, and packaging process. The process flow of powdered organic fertilizer includes the above-mentioned crushing process, fermentation process, and packaging process.

The core stage of the granular fertilizer production line is the granulation process. In the granulation process, the roller press granulator is generally used more. The roller press granulator has low investment and long service life. It is an organic fertilizer equipment that investors are more satisfied with. If it is necessary to add some NPK to the organic fertilizer to produce organic and inorganic fertilizers, the fertilizer granulator needs to choose a fertilizer granulator that is practical for organic and inorganic granulation. The fertilizer granulator I recommend here is NPK and organic fertilizer granulator.

Fermentation process of hydraulic tank type organic fertilizer turning machine

fertilizer granulator Dec 27, 2024

The hydraulic tank type organic fertilizer turning machine is a commonly used organic fertilizer production equipment, suitable for large-scale organic fertilizer factories. Its fermentation process generally includes the following steps:

technological process

Raw material preparation: Firstly, collect organic materials such as livestock and poultry manure, crop straw, urban sludge, etc., and crush and mix them as needed to adjust the C/N ratio and moisture content to meet the requirements of suitable fermentation.

Entering the tank: Place the prepared raw materials into the fermentation tank of the pre designed hydraulic tank type organic fertilizer turning machine. The fermentation tank is generally long and rectangular, which facilitates subsequent turning operations.

Inoculate fermentation bacteria: In order to accelerate the fermentation process, specialized fermentation agents can be added to the raw materials, which can quickly initiate the fermentation reaction and improve efficiency.

Hydraulic flipping: Through a hydraulic driven flipping device, it moves back and forth in the fermentation tank, flipping the bottom of the raw materials to the top, and the surface of the raw materials moves down to ensure that all raw materials can receive sufficient aerobic fermentation. This process can effectively control the fermentation temperature, avoid local overheating, and also help to discharge carbon dioxide and moisture, and introduce fresh air.

Temperature control: During the fermentation process, it is necessary to maintain a certain temperature. The ideal fermentation temperature range is generally between 50 ° C-60 ° C. Overheating or undercooling is not conducive to the activity of microorganisms. Therefore, it is necessary to regularly check the internal temperature of the fermentation pile and take heating or cooling measures if necessary.

Regular testing: During the fermentation period, key parameters such as moisture content, pH value, and oxygen content of the raw materials should be regularly checked to ensure stable and controllable fermentation process.

Post fermentation maintenance: After the fermentation reaches the expected effect, the raw materials can be moved out of the fermentation tank, spread out and left to air for a period of time, allowing them to cool naturally and further age, making the fertilizer more stable.

Finished product processing: Finally, after screening, crushing, packaging and other processes, mature organic fertilizers can be obtained.

The characteristics of the hydraulic tank type organic fertilizer turning machine are its high efficiency, high degree of automation, and suitability for large-scale production. However, attention should also be paid to the maintenance of the machine during use to extend its service life and ensure fermentation quality. Through rational design and precise operation, the production efficiency and quality of organic fertilizers can be greatly improved, contributing to the sustainable development of agriculture.

Cow manure organic fertilizer turning machine fermentation processing organic fertilizer

fertilizer granulator Dec 27, 2024

The cow manure organic fertilizer turning machine is a key equipment that converts organic waste such as cow manure into high-quality organic fertilizer. Through biological fermentation technology, it decomposes organic matter and concentrates nutrients. The following are the specific working principles and processing steps:

working principle

The cow manure organic fertilizer turning machine is based on the principle of aerobic fermentation, using microorganisms to decompose organic matter under suitable temperature, humidity, and oxygen conditions, producing heat and carbon dioxide. This process is called “composting”. The machine regularly flips the compost pile to provide sufficient oxygen, accelerate microbial activity, and promote rapid degradation of organic matter.

Processing steps

Raw material collection and pretreatment: Collecting fresh or stored cow manure for a period of time generally requires crushing, screening, and removing large impurities. Sometimes, a certain amount of auxiliary materials such as straw, sawdust, and husks need to be added to adjust the carbon nitrogen ratio and promote microbial growth.

Moisture regulation: The moisture content of cow manure should be controlled at around 50% -60%, as too high or too low can affect the fermentation effect. If there is insufficient moisture, it is necessary to spray an appropriate amount of water; If there is too much water, measures need to be taken to dehydrate.

Stacking fermentation: Pre treated cow manure is stacked into a pile of a certain height and width, and the turning machine is started for initial stacking. At this time, bacterial strains can be added to accelerate the fermentation speed.

Pile turning ventilation: Use an organic fertilizer turning machine to regularly turn over the compost pile, ensuring sufficient oxygen and dissipating the generated heat, maintaining the ideal fermentation temperature (usually 50 ° C-60 ° C), and accelerating water evaporation to promote microbial activity.

Secondary fermentation and maturation: After the first turning of the compost pile, continue to observe the temperature changes inside the pile, and if necessary, turn the pile again until the compost is completely mature, usually taking several weeks. During this period, cow manure will gradually turn dark brown and the odor will become lighter.

Post processing: Fermented and matured organic fertilizers need to be screened to remove undecomposed large chunks, further dried to achieve the desired moisture content (about 10% -15%), and then packaged for storage.

Quality testing: Finished organic fertilizers must undergo quality testing by professional institutions to confirm that pH value, nutrient content, pathogen and other indicators are qualified before they can be put on the market.

The cow manure organic fertilizer turning machine not only processes a large amount of agricultural production waste, reducing environmental pollution, but also produces organic fertilizers rich in beneficial microorganisms and organic matter, improving soil structure, increasing crop yield and quality, and is an important component of agricultural circular economy and sustainable development.

What equipment does the chicken manure organic fertilizer production line need to process organic fertilizer

fertilizer granulator Dec 27, 2024

1. Prepare the manure that needs fermentation. Chicken manure contains a large number of Bacillus, which is aerobic fermentation bacteria. If natural reproduction is used, the heating time will be prolonged, so it is possible to consider adding fermentation bacteria or using reflux to speed up the heating.

2. Composting of chicken manure: when the prepared chicken manure is spread with bacteria, the pile height should not be too short and the volume should not be too small. The requirements: the pile height is 1.5-3m, and the width should be considered comprehensively according to the type of fertilizer manufacturing equipment, and the length should consider factors such as fermentation period, plant size and local climate. The larger the heap, the higher the fermentation in winter, especially in the cold areas.

3、 Adjust the moisture. The moisture content of fermented chicken manure should be controlled at 40 ≤ 65%. Water judgment: hold a pig dung tightly, finger to see watermark rather than dripping water, it is appropriate to fall on the ground. The slow fermentation of water and poor water ventilation will lead to the work of anaerobic bacteria and produce odor. Therefore, we must master the water content.

4. Start up temperature. The starting temperature shall be above 5-15 ℃ (it can be operated in four seasons, not affected by the fermentation in the seasons, winter or in the greenhouse), and the fermentation temperature shall be controlled below 70-75 ℃.

5. Mix well and breathe. The fermentation of chicken manure should be good (consuming) aerobic fermentation. Therefore, oxygen supply measures should be added during the operation to make mixing, frequent rotation and proper ventilation, otherwise it will produce anaerobic fermentation and produce foul smell, which will affect the effect of fertilizer. Good fermentation can ensure the effect of the organic fertilizer granulator.

6. Fermentation is complete. Generally speaking, after 48 hours of accumulation of chicken manure, the temperature rises to 50°C-60°C, and can reach 65°C on the third day. Turn over once at this high temperature. Generally, after more than 20 days of fermentation, the temperature drops to a certain extent. .

After the compost is completed, the fertilizer production line further processes the chicken manure to make commercial organic fertilizer.
