Organic fertilizer trough type turner is a commonly used fermentation equipment in the production process of organic fertilizers, mainly used for composting solid organic waste. The fermentation principle and advantages are as follows:

Fermentation principle

The fermentation principle of the trough type flipping machine is mainly based on the aerobic fermentation process. In the fermentation tank, organic waste (such as livestock manure, crop straw, etc.) is piled up into a certain height of material pile. Under the action of microorganisms, organic matter is decomposed, releasing heat and raising the temperature of the pile. This process requires sufficient oxygen to maintain microbial activity and fermentation efficiency.

The trough type flipping machine flips the materials from the surface of the pile to the inside and from the inside to the surface, ensuring that the entire pile can come into contact with fresh air and provide sufficient oxygen for microorganisms to carry out aerobic fermentation. Flipping can also promote uniform temperature distribution inside the stack, avoid local overheating, and help remove odor gases produced during fermentation.

advantage

Improve fermentation efficiency: By regularly flipping and throwing, ensure sufficient oxygen supply inside the heap, accelerate the decomposition of organic matter, and shorten the fermentation cycle.

Uniform fermentation: The flipping process ensures that the entire pile of materials can participate in fermentation evenly, avoiding incomplete or excessive local fermentation.

Temperature control: Flipping helps to control the temperature of the pile, avoid local overheating that may lead to a decrease in microbial activity, and ensure the stability of the fermentation process.

Reduce odors: By flipping and throwing, odors such as ammonia and hydrogen sulfide generated during the fermentation process can be promptly eliminated, improving the working environment.

Improving fertilizer quality: A uniform fermentation process helps to increase the nutrient content of organic fertilizers, reduce harmful substances, and enhance fertilizer quality.

High degree of automation: The trough type flipping machine can achieve automated operation, reduce manual intervention, and improve production efficiency.

Strong adaptability: The trough type flipping machine is suitable for the fermentation treatment of various organic wastes, such as livestock manure, crop waste, etc., with a wide range of applications.

In summary, the trough type turner improves the efficiency and effectiveness of organic waste composting treatment by optimizing fermentation conditions, and is an indispensable key equipment in organic fertilizer production.

The granulation process of organic fertilizer production line is a key step in processing organic raw materials into granular fertilizers, which usually includes multiple stages to ensure the quality and stability of the final product. The following is a typical granulation process for processing fertilizers in an organic fertilizer production line:

1. Raw material pretreatment

Raw material collection and crushing: Collect fresh or dry organic materials, such as livestock manure, crop straw, etc., and use a crusher to crush them to a particle size suitable for granulation.

Raw material mixing: Mix the crushed raw materials with additives (such as microbial agents, nutrients, etc.) evenly to enhance the nutrient content and biological activity of the fertilizer.

2. Fermentation treatment

Raw material fermentation: The mixed raw materials are stacked in a fermentation tank or fermentation chamber, and through natural or controlled fermentation, organic matter is decomposed by microbial action to produce high-temperature sterilization, while converting the nutritional components in the raw materials.

3. Drying and cooling

Material drying: After fermentation, the material needs to be dried using a dryer (such as a drum dryer or belt dryer) to remove excess moisture for granulation and subsequent processing.

Material cooling: The dried material has a high temperature and needs to be cooled to near room temperature using a cooling machine (such as a cooling drum) to prevent material adhesion during subsequent granulation processes.

4. Granulation

Pre treatment before granulation: Depending on the type of organic fertilizer granulator, further crushing or pre wetting of the cooled material may be required to meet the feeding requirements of the granulator.

Granulation: The pre treated material is sent to a granulator (such as a disc granulator, a roller extrusion granulator, a drum granulator, etc.), where it forms particles with a certain shape and size under the action of the granulator.

5. Particle screening and crushing

Particle screening: Use vibrating screens and other equipment to screen out particles that do not meet the size requirements, and perform secondary granulation or crushing treatment.

Crushing large particles: For the selected oversized particles, use a crusher to crush them to the desired particle size.

6. Particle post-treatment

Particle drying: For particles with high moisture content, it may be necessary to dry them again to ensure the stability and storage conditions of the final product.

Particle cooling: The dried particles need to be cooled to avoid excessive dust generation during the packaging process.

7. Packaging and Storage

Quantitative packaging: Use an automatic packaging machine to quantitatively package cooled particles into bags or boxes for easy sales and transportation.

Finished product storage: Packaged organic fertilizer products should be stored in a dry and ventilated warehouse to avoid moisture and contamination.

The granulation process of organic fertilizer production line is a systematic engineering, with each link closely connected and interdependent. It needs to be reasonably configured and adjusted according to the characteristics of raw materials, production scale, and final product requirements to ensure the efficiency of the production process and the high quality of the products.
