Process of Cow Dung Fermentation Organic Fertilizer Production
It is a headache to mention cow dung in farms. Cow dung not only pollutes the environment, but also seriously affects the living environment of residents. In fact, cow dung contains a large amount of nutrients needed for crop growth. It is a new project of energy saving and environmental protection to make cow dung into organic fertilizer by adding biological strains. The production of organic fertilizer from cow dung is mainly by fermentation, crushing, The process of drying, cooling and pelletizing. The daily output of a cow dung is about 40 kilograms. It is very suitable for a 500-head cattle farm to establish a small organic fertilizer production line. How to deal with the cow dung in the cattle farm? How to make organic fertilizer from cow dung？
1. Sterilization and fermentation
When cow dung is fermented for organic fertilizer, it is necessary to sterilize and ferment cow dung. First, the collected cow dung needs to be mixed with straw, wheat bran, rice bran, sawdust and other absorbent wastes with good water absorption, and the other party is sterilized and fermented in the fermentation tank, waiting for the cow dung fermentation to be completed.

2. Mixing fertilizer
After the cow dung is fermented, it can be taken out and put into the batching bin, and inorganic fertilizers rich in nitrogen, phosphorus and potassium are added to it, and then the cow dung and the fertilizer are fully pulverized by a crusher, and then the Use a mixer to thoroughly mix the manure and fertilizer.
3. Making particles
After the mixing is completed, the cow dung can be directly put into the organic fertilizer granulator to make granular fertilizer. During the production process, it is necessary to constantly check the particle size of the fertilizer. If a larger granular fertilizer is found, it is necessary to return to the granulator and re-granulate it.
4. Drying and cooling
After the fertilizer is made, the cow manure fertilzier needs to be dried with a dryer. Further remove water to meet the standard requirements of organic fertilizer moisture content. After waiting for the moisture in the granular fertilizer to evaporate, you can put it in a cool and dry environment to dry, or use a cooler to cool it, which will help the pellets to be stored and kept in good quality.
5. Packaging
The cooled granular cow dung fertilizer is transported to the finished product warehouse through the fighter elevator, and the granular material is quantitatively weighed and packaged by the automatic packing scale.
