Organic fertilizer is the "nutritional cornerstone" of green agriculture. The scientific nature of its production process directly determines its effectiveness. The following details the standardized organic fertilizer production process to help you produce high-quality fertilizer.
Step 1: Raw Material Selection and Proportioning
Select organic raw materials such as livestock and poultry manure, straw, and mushroom residue, and sort them to remove impurities. A precise carbon-nitrogen ratio of 25-30:1 is precisely blended, for example, chicken manure and corn straw should be mixed at a ratio of 6:4. A composting agent is added to activate microbial activity.
Step 2: High-Temperature Fermentation
The mixed raw materials are fed into a fermentation tank and stirred 2-3 times daily using a compost turning machine, maintaining a temperature of 55-65°C. This temperature kills pathogens, insect eggs, and accelerates the decomposition of organic matter.
Step 3: Crushing and Screening
The composted material is crushed to an 80-mesh fineness using a chain crusher, then passed through a vibrating screen to remove impurities and ensure uniform particle size. Achieving the required fineness increases the fertilizer's contact area with the soil by 30%, improving crop absorption efficiency.
Step 4: Granulation and Drying
A disc granulator is used to granulate the powder into 3-5mm granules. The powder is then dried (60-70°C) to remove excess moisture to less than 15%. A cooling system is also included, increasing granule hardness by 25%, reducing transportation losses.
Step 5: Coating
The dried and cooled granules enter the coating machine, where a specialized coating agent is sprayed onto the granules to form a uniform protective coating. Coating not only reduces moisture absorption and clumping during storage and transportation, but also controls nutrient release, extending the fertilizer's effective life.
Step 6: Metering and Packaging
The coated product is automatically metered and packaged in 25kg bags. This fully mechanized process reduces manual contact and ensures product cleanliness.
Following this standardized process ensures that organic fertilizers meet national standards while achieving mass production and increased efficiency.
