Straw, as a rich agricultural byproduct, can be transformed into organic fertilizer through scientific fermentation technology. This not only effectively solves the environmental pollution caused by straw burning, but also improves soil structure and increases soil fertility. The following are the main organic fertilizer equipment required for straw fermentation to produce fertilizers:
Firstly, straw needs to be crushed into smaller fragments to increase surface area and facilitate better microbial activity. This step can be completed using a straw crusher or a comprehensive crusher.
Mix the crushed straw evenly with animal manure, organic waste (such as chicken manure, cow manure), microbial agents, and other organic substances (such as mushroom residue, green manure, etc.) to prepare for the fermentation process. This device needs to have good mixing effect to ensure sufficient contact between various raw materials.
3. Fermentation facilities
a. Bar stack fermentation
This is one of the most common fermentation methods, which does not require special equipment and only requires laying a layer of straw mixture on the ground, providing oxygen and heat through natural fermentation and regular flipping.
b. Fermentation tank
For a more efficient and controllable fermentation environment, enclosed fermentation tanks equipped with heating, ventilation, and flipping machinery can be used to regulate temperature and humidity, accelerating the fermentation process.
4. Temperature and humidity sensors
Monitor and control the temperature and humidity inside the fermentation pile to ensure that the conditions are within the most suitable range for microbial activity (usually the temperature should be between 50 ° C and 60 ° C, and the humidity should be about 50% to 60%).
5. Organic fertilizer turning machine
Used to flip the mixture during fermentation to ensure oxygen supply and promote uniform fermentation. There are various types of stackers, such as tracked and self-propelled, which can be selected according to production scale.
6. Drying machine
After fermentation, the fertilizer needs to be dried to reduce its moisture content to a suitable level for storage. Drying can be done through natural air drying or using a hot air dryer.
7. Organic fertilizer screening machine
Used for screening and grading organic fertilizers after fermentation, removing incompletely decomposed residues to ensure consistency in fertilizer quality.
8. Packaging machine
Finally, pack the finished organic fertilizer into bags for easy sales and use.
auxiliary equipment
Conveyor: Used for transporting and conveying materials.
Control system: Automatically manage the operating parameters of the entire equipment to improve production efficiency and safety.
When establishing a straw fermentation fertilizer production line, environmental protection measures should also be considered, such as installing exhaust gas treatment systems to reduce emissions and protect the environment. In addition, reasonable planning of production processes and optimization of resource allocation can significantly reduce costs and improve output efficiency. Before selecting equipment, it is recommended to carefully evaluate specific requirements and determine the optimal configuration plan.
