The production process of organic fertilizer powder is an important production technology, which can make organic fertilizers into powder form for easy storage, transportation, and application. This production process is generally divided into several processes, including raw material processing, proportioning, fermentation, dehydration, and powder making.
Pre processing; After the composting raw materials are transported to the yard, they are weighed by a scale and sent to a mixing and stirring device. They are mixed with organic wastewater from production and domestic use in the factory, and composite bacteria are added. The moisture and carbon nitrogen ratio of the composting fertilizer are roughly adjusted according to the raw material composition, and then mixed before entering the next process.
One fermentation; The mixed raw materials are fed into a fermentation tank using a loader and stacked into a fermentation pile. A fan is used to force ventilation from the bottom of the fermentation tank upwards for oxygen supply. At the same time, the pile is flipped for about 2 days and supplemented with water and nutrients. The fermentation temperature is controlled between 50 ℃ and 65 ℃ for aerobic fermentation. The fermentation cycle for this project is 8 days.
Post processing; After the fermented semi-finished product is discharged, it is ready to enter the next process.

Equipment and granulation process of powdered organic fertilizer production line
The process determines the equipment, and the equipment used in the production line of powdered organic fertilizer is generally relatively rare. Usually as follows:
Fertilizer equipment one, fermentation turner or organic fertilizer turner, which is a device used for both powdered and granular organic fertilizers;
Fertilizer equipment 2, material crusher, is one of the essential equipment for processing organic fertilizers;
Fertilizer equipment three, screening machine, screens out raw materials that exceed the powder requirements and returns them for further crushing;
Fertilizer equipment four, automatic weighing and packaging machine.
