Do you want to make organic fertilizer from high moisture waste? And how to make organic fertilizer after dehydration? The first step is to reduce water by means of dewatering machine. After dewatering, the moisture content of the solid manure is about 30%. Thus, you can produce organic fertilizer through a fermentation process. To initiate the fermentation, it is necessary to introduce fermentation strains, which play a key role in enhancing the production efficiency. Besides, the process involves the following steps.
Top 3 Key Steps to Make Manure into Organic Fertilizer
1. Dewatering
Firstly, you can utilize our screw press dewatering machine to remove excess water in the solid manure. Then, this will reduce the moisture content to around 30-40%. In addition, the dewatering machine efficiently separates the liquid and solid components, resulting in a more manageable material for further processing.
2. Fermentation
The second step is a fermentation process. During this stage, you should place the solid manure in advance in a suitable container (fermentation groove or tank) or composting piles. Addtionally, you should add special fermentation strains to aid decomposition and promote the breakdown of organic matter. Since, these strains help to hasten the transformation of nutrients, making them more readily available for plants.
3. Pelleting
Once the fermentation is complete and the moisture level has reached the desired percentage, you can make granules from the organic waste. Pelleting involves shaping the organic matter into compact pellets or granules, making it easier to handle, transport, and apply to fields or gardens. At this time, you can consider our organic fertilizer granulation machines with many models. Also, buying a coating machine is a good option. Then, in this machine, you can enrich additional nutrients or additives in the fertilizer pellets to further enhance their nutritional value.
Conclusion
By following this process, from dewatering to fermentation and pelleting, the solid manure can be transformed into high-quality organic fertilizer. To be honest, this organic fertilizer is rich in nutrients, improves soil fertility, and promotes sustainable agricultural practices.

When it comes to maintenance, you can simply clean the sieve mesh after work completion will keep the machine in top condition.
For optimal performance of our dewatering machines, it’s crucial that the input material begins with a moisture content of at least 50%. This initial moisture level is necessary to ensure efficient and effective dehydration. Once the material has undergone the dehydration process, you can anticipate a residual moisture content of approximately 30%. This significant reduction in moisture allows the material to be suitable for a wide range of uses, including further processing or safe storage, without the risk of spoilage.

The drum dryer is a heat conduction dryer. During the work of the rotary drum dryer, the drying drum is continuously rotated, so the material is heated in multiple directions.This can maximize the use of heat energy. The utilization rate of heat energy of the rotary drum dryer is more than 95%. It is an essential product under the situation of energy saving and environmental protection.The drying mechanism is that when the temperature at the bottom of the dryer equipment reaches 400°C-800°C, the material is sent from the feeding chute by the elevator.Due to the angle difference and rotational movement of the lifting plate, the material is thrown by the lifting plate to move vertically . The materials are evenly dispersed in the dryer and fully contacted with the hot air to speed up the drying heat transfer and mass transfer. The contact time between the materials and air is extremely short, and the drying time is generally 0.5~5 seconds. For heat-sensitive or low-melting point materials, it will not cause overheating or decomposition to affect its quality.
During the drying process,the hot gas is generated by the lower hot blast stove,and moves from bottom to top.It fully contacts with the materials, and transfers heat to the material through heat conduction, convection, radiation and other ways.Therefore, the temperature of the materials continues to rise and the water is continuously evaporated.Under the action of the inclined lifting plate and the hot air flow, the materials that finally meet the moisture requirement is discharged from the lower outlet, while the gas with water vapor is drawn out by the fan through the chimney. The whole process is carried out in a closed environment, thereby reducing environmental pollution during the drying process, preventing the spread of epidemic diseases, and having good economic and social benefits.
Airflow drying adopts parallel flow operation of material and gas, so the material temperature and air temperature can reach a reasonable state from the beginning to the end.The drying time is short, and the thermal efficiency is high, so a higher drying temperature can be used. Moreover, the rotary dryer also has the characteristics of wide application range, simple operation, stable operation, low energy consumption and high output. The use of this equipment can achieve the best economic benefits with the smallest investment, the lowest energy consumption, the fastest speed, the least manpower and space.
If there is something wrong with the rotary drum dryer in the drying process,it should stop working at once.The most important thing is that you are supposed to find the cause of breakdown and solve the problem timely.For example,if the dryer drum bearing makes some noise,you can add some lubricant to reduce friction;if the supporting parts are broken,you should replace the old supporting parts with new ones.If you are not reassured, we have prepared a video on installation, operation, replacement, repair and maintenance of parts.The video is animated and easy to understand.If you have any problems,you can e-mail or call us at any time.We will spare no efforts to provide you with help without delay.
