Powdered organic fertilizer production lines are usually used to convert agricultural waste such as livestock manure, crop straw, etc. into powdered organic fertilizers. The following is the basic process flow of the powdered organic fertilizer production line:

Raw material pretreatment:

Collection: Firstly, collect agricultural waste such as livestock manure, crop straw, etc.

Crushing: Use an organic fertilizer crusher to crush raw materials into small particles to increase surface area, facilitate microbial action, and subsequent treatment.

Fermentation:

Mixing: Mix the crushed raw materials with microbial agents, excipients, etc. evenly to promote the fermentation process.

Composting: Stacking the mixed materials in a fermentation tank or fermenter for natural or forced fermentation. During the fermentation process, microorganisms will decompose organic matter, kill pathogens and weed seeds, and improve the nutritional value of fertilizers.

Drying and screening:

Drying: Fermented materials usually contain high moisture content and need to be dried by a dryer to reduce moisture content and facilitate storage and use.

Screening: The dried material is screened through a screening machine to remove large particles and impurities, resulting in a powdered organic fertilizer.

Packaging:

Measurement and packaging: The sieved powdered organic fertilizer is measured and then packaged using an automatic packaging machine for sale or use.

The process flow of the powdered organic fertilizer production line is relatively simple, and the equipment investment is low, making it suitable for small-scale production. This type of fertilizer is suitable for direct spraying or as a raw material for compound fertilizers. However, powdered organic fertilizers may generate dust during storage and transportation, which can have a certain impact on the environment. Therefore, in practical operation, appropriate measures need to be taken, such as increasing humidity, using dust covers, etc., to reduce dust pollution. With the advancement of technology and changes in market demand, the production line of powdered organic fertilizer is also constantly being optimized and upgraded to improve production efficiency and environmental performance.
