Technical adaptation strategies for organic fertilizer production lines in low-temperature environments

fertilizer granulator Oct 11, 2025

The impact of low temperatures in northern winter on organic fertilizer fermentation efficiency has necessitated low-temperature adaptation of organic fertilizer production lines. Key measures focus on maintaining fermentation temperature and raw material pretreatment.

In terms of bacterial strain selection, production lines must utilize low-temperature-tolerant composite inoculants to ensure viability at temperatures between 5-15°C (with a viable bacterial count retention rate exceeding 85%), shortening fermentation start-up time to within 24 hours.

In terms of workshop design, insulation and a photovoltaic-assisted heating system are required to maintain the fermentation room temperature above 10°C through solar heating. Some organic fertilizer production lines also utilize closed fermentation chambers, utilizing bioheat generated during the fermentation process to maintain a constant internal temperature (temperature fluctuations within ±3°C).

In raw material pretreatment, to address the difficulty of raw materials such as straw degrading at low temperatures, production lines incorporate a pre-crushing step (crushing the raw materials to 0.5-1 cm) and use hot water humidity control (controlled at 30-40°C) to raise the initial raw material temperature and ensure fermentation efficiency.

These adaptation measures have increased the capacity utilization rate of organic fertilizer production lines in northern winter from the original 50% to over 80%, and the organic matter content of finished fertilizers has stabilized at over 55%, effectively ensuring the supply of fertilizers for agricultural production in northern winter.

Moisture proofing adaptation techniques for organic fertilizer production lines

During the rainy season, humidity is high, and organic fertilizer raw materials easily absorb moisture and clump together. This can lead to production line blockages and slow fermentation if not carefully considered. In fact, smooth production can be achieved by making three moisture-proof adjustments to the organic fertilizer production line.
Include a moisture control step in the pretreatment process. Install a small drying device before the pulverizer to reduce the moisture content of raw materials such as straw and manure from over 65% to 55%-60%, preventing wet materials from sticking to the pulverizer blades.
Add a moisture detector to the mixer outlet. If the raw materials are too wet, it will automatically prompt the addition of dry sawdust, eliminating the need for empirical judgment and reducing the risk of subsequent granulation blockages.

The fermentation process requires both rain protection and ventilation. Build a simple canopy over the fermentation pile to prevent rain from directly falling on it. After each turning, place a layer of dry straw on the surface of the pile. This absorbs moisture and allows for ventilation inside the pile, preventing stagnation. If the humidity in your workshop exceeds 80%, install several industrial fans in the fermentation area to improve air circulation and prevent the fermentation cycle from being extended during the rainy season.
The pelletizing process requires timely cleaning. During the rainy season, raw materials are prone to sticking to the pelletizer’s ring die. Every two hours of production, stop the fertilizer granulator and use a special scraper to clean the sticky material from the die holes. Don’t wait until it accumulates.
The conveyor belt at the discharge port can be covered with an anti-stick mat to prevent pellets from sticking, reducing cleaning time. With these adjustments, your organic fertilizer production line can operate as efficiently as normal during the rainy season, eliminating the need to worry about wet raw materials and slow fermentation.

How can organic fertilizer production lines adapt to the needs of ecological agriculture?

fertilizer granulator Oct 11, 2025

Ecological agriculture’s requirements for “no chemical additives” and “full-cycle composting” of fertilizers are driving targeted adjustments to organic fertilizer production lines.

In ecological farming, the use of chemical regulators is prohibited. Organic fertilizer production lines must optimize the microbial community structure to achieve natural composting of raw materials. For example, complex microbial agents can be used instead of traditional chemical ripening agents to ensure that no exogenous pollutants are introduced during the fermentation process.

At the same time, ecological agriculture emphasizes the “cultivation-livestock cycle.” Organic fertilizer production lines must adapt to a variety of ecological raw materials, such as rice husks and mushroom residues, using precise pulverization and mixing processes to ensure balanced nutrient release.

Furthermore, to meet the demand for “light and simplified fertilization” in ecological farming, end-of-line production lines must enhance granulation and slow-release technologies to adapt fertilizers to various ecological farming scenarios, such as drip irrigation and broadcasting, thus achieving a closed loop of “fertilization-growth-soil maintenance.”

At present, the application rate of products of this type of organic fertilizer production line adapted to ecological agriculture in ecological fruit and vegetable planting has increased by 35% compared with ordinary production lines. After some ecological tea gardens adopted this type of fertilizer, the tea polyphenol content in tea increased by an average of 8%, and the pass rate of pesticide residue detection remained at 100%, further verifying the adaptability of the production line to ecological planting.

Key points for retrofitting organic fertilizer production lines under environmental compliance requirements

fertilizer granulator Oct 10, 2025

With increasingly stringent environmental protection policies, environmental retrofitting of organic fertilizer production lines has become an industry imperative, focusing on the treatment of “three wastes” and compliance upgrades.

For waste gas treatment, organic fertilizer production lines must be equipped with sealed fermentation chambers and ammonia collection systems. Biofilter technology is used to control ammonia concentrations generated during the fermentation process to within standards. Some areas also require VOC monitoring equipment to ensure real-time upload of emission data.

For wastewater treatment, production lines must establish a recycling system to sediment and filter wash water and condensate before reusing them for raw material moisture conditioning, achieving zero wastewater discharge.

For solid waste treatment, optimized screening processes are employed to re-crush fermentation residues before mixing them back into fermentation, achieving full solid waste utilization.

Furthermore, the environmental impact assessment process imposes stricter requirements on production line site selection and capacity planning, such as requiring them to be at least 500 meters away from residential areas and designing production capacity to match the regional environmental carrying capacity. Although these transformations increase initial investment (usually the transformation cost of a single production line accounts for about 15%-20% of the total investment), the energy consumption of the organic fertilizer production line can be reduced by 12%-18% after the transformation.

How to prevent blockages in new type organic fertilizer granulators?

fertilizer granulator Oct 10, 2025

Many people occasionally encounter blockages when using new type organic fertilizer granulators (raw material gets stuck in the granulation chamber, preventing pellets from coming out). However, if you take three steps in advance, this problem is virtually eliminated.

First, avoid any hard lumps in the raw material. Whether it’s manure or straw, lumps may form after fermentation. Before feeding, be sure to use a crusher to break up any lumps. Keep lumps no larger than 1 cm, otherwise they will get stuck in the die holes of the new organic fertilizer granulator. Accumulating these lumps will cause a blockage.

Second, control the moisture content of the raw material. Although new type organic fertilizer granulators are moisture-resistant, raw material that is too moist (over 65%) will stick to the granulation chamber, while too dry (less than 45%) will produce fine powder and clog the screen. Before each feeding, grab a handful of raw material and form a ball that breaks apart easily. This will ensure the raw material flows smoothly through the granulation chamber without blockage.

Third, perform a component inspection every day before starting the machine. Check the pressure roller of the new type organic fertilizer granulator to see if it’s stuck and the scraper at the discharge port to see if it’s blunt. If the roller can’t turn or the scraper is blunt, the pellets won’t come out and the machine will jam. Simply turn the roller manually and check the scraper to see if it’s sharp. If there’s any problem, adjust it immediately to avoid jams.

How do new type organic fertilizer granulators reduce dust and noise?

fertilizer granulator Oct 10, 2025

Organic fertilizer plants now have to meet environmental standards, and dust and noise are prone to complaints. New type organic fertilizer granulators offer more comprehensive dust and noise reduction measures than traditional models, eliminating the need for extensive additional environmental protection equipment.
Let’s first discuss dust reduction. Both the feed and discharge ports feature dust-proof designs. The feed port features a soft dust cover that fits over the conveyor belt outlet, preventing dust from escaping as the material falls. The discharge port incorporates a “deflector + atomizing nozzle” system. As the granules emerge, the deflector guides them in a direction, while the atomizing nozzle sprays a small amount of water (just enough to wet the dust without affecting the particles) to suppress any raised fines. This reduces dust concentration in the workshop by over 60%, eliminating the need for separate, large-scale dust removal equipment.

Next, consider noise reduction. The new type organic fertilizer granulator features a soundproofing pad between the motor and the granulation chamber, resulting in a 10-15 decibel reduction in operating noise compared to traditional machines. For example, while traditional machines typically make a tractor-like sound, the new type organic fertilizer granulator’s operation resembles a washing machine spinning, allowing for normal conversation in the workshop without earplugs. Furthermore, its rollers and ring die work together more smoothly, eliminating the sharp noises caused by friction and preventing disturbance to nearby residents.

Organic fertilizer production line was used to process chicken manure

fertilizer granulator Oct 10, 2025

Organic fertilizer is favored by agricultural production because of its ability to improve soil structure, increase organic matter content and enhance soil fertility. Among them, chicken manure as a high-quality organic fertilizer raw material, its processing has attracted much attention. This article will explore how to efficiently process organic manure from chicken manure through organic fertilizer production lines and ensure its quality and safety.
 

1. Raw material preparation and pretreatment

 
Chicken manure requires strict pretreatment before processing to eliminate pathogens and weed seeds in it. This usually involves composting treatment, which breaks down organic matter through the action of microorganisms while releasing heat to achieve bactericidal and deodorizing effects. The pre-treated chicken manure can enter the organic fertilizer production line for further processing.
 

2. Drying and sterilization of chicken manure

 
One of the key steps in an organic fertilizer production line is drying. By using professional drying equipment, such as Rotary Dryer Machine, the moisture content of chicken manure can be effectively reduced, its stability can be increased, and the subsequent granulation process can be facilitated. In addition, the high temperature during the drying process can further sterilize, ensuring the safe use of organic fertilizers.

3. Ingredient mix and nutrition balance

 
In the organic fertilizer production line, chicken manure is usually mixed with other auxiliary materials such as straw, shells, etc., to adjust the carbon nitrogen ratio and ensure the nutrient balance of organic fertilizer. This step is done through the Bulk Blending Fertilizer Production Line, ensuring that the final product can meet the needs of the different crops.

4. Granulation molding

 
The mixed raw materials will enter the granulator, such as the Fertilizer Granules Compaction Machine, for molding processing. This step forms the raw material into a uniform granular form that is easy to apply and store. Granulation can not only improve the appearance of organic fertilizer, but also improve its dispersion and absorption rate in the soil.

5. Screening and packaging

 
The organic fertilizer after granulation needs to be screened by Rotary Screening Machine to ensure uniform particle size and meet product quality standards. The qualified product is then packaged to become the final chicken manure organic fertilizer product.

6. Quality control

 
In the whole process of organic fertilizer production line, quality control is an indispensable link. By regularly testing the number and activity of microorganisms in organic fertilizers, the effectiveness and safety of the product can be assessed. For example, the application of bio-organic fertilizer can increase the capacity of soil microorganisms to utilize carbon sources, improve microbial nutrient conditions, maintain high microbial activity, and increase soil microbial diversity.
 
Through the above steps, the organic fertilizer production line can efficiently convert chicken manure into high-quality organic fertilizer products. This processing method not only improves the efficiency of resource utilization, but also helps to improve the quality and safety of agricultural products, and also contributes to the sustainable development of agriculture. With the advancement of technology and the growth of market demand, organic fertilizer production lines will continue to play an important role in modern agricultural production.

How do new type organic fertilizer granulators adapt to different organic fertilizer raw materials?

fertilizer granulator Oct 10, 2025

New type organic fertilizer granulators are more flexible than traditional models. Whether it’s straw, manure, mushroom residue, or distiller’s grains, they can be adapted with minimal adjustments without having to replace equipment.

If using fermented straw for granulation, this raw material is fibrous and somewhat loose, making it difficult to produce compact pellets. Add 5%-8% bentonite (a common binder) to the raw material, mix it thoroughly before feeding it into the new type organic fertilizer granulator, and increase the roller pressure. This will ensure compact pellets without breaking them up and damaging the organic matter in the straw.

For wet, sticky raw materials like chicken manure and pig manure, the biggest concern is clogging the granulator. Instead of adding too much binder, add about 10% dry mushroom residue to reduce moisture. Also, slow the new type organic fertilizer granulator’s feed rate to allow the raw material to fully form in the granulation chamber. The resulting pellets are smooth and less likely to stick to the machine.
When it comes to fine raw materials such as mushroom residue and wine lees, they have moderate viscosity and do not require additional adhesives, which saves materials and time.
