Because cow dung is rich in various nutrients, after being properly treated by the cow dung organic fertilizer production line processing technology and process, a variety of harmless, resource-based, and efficient value-added products can be produced, which can prevent and control environmental pollution while also obtaining good economic and social benefits.

How does the cow dung organic fertilizer production line treat cow dung? There are currently three methods for treating cow dung:

1. Decomposition method: also known as the insect method, it uses flies, snails, earthworms and other lower animals to decompose feces, so as to provide animal protein and treat feces. For example, using cow dung to raise earthworms, it is estimated that 15,000 to 20,000 fresh earthworms can be harvested per square meter of culture medium, about 30 to 40 kg. Earthworm manure is an efficient organic fertilizer and can be used as a high-quality organic fertilizer for plants. The earthworms produced are high-quality animal proteins, which are used in fishing bait, medicine and other industries, and do not cause secondary pollution to the environment.

2. Drying method: The drying method is divided into mechanical drying method and natural drying method. The mechanical drying method uses related equipment for drying, which can achieve the purpose of deodorization and sterilization. This method is low-cost and easy to operate, but it is greatly affected by the weather and is prone to environmental pollution.

3. Fermentation method: The fermentation method is to add certain microbial agents or enzyme preparations and other auxiliary materials to cow dung, and then ferment it at a suitable temperature, and use the resulting product to feed chickens, pigs, fish and other animals. For example, cow dung is fermented for silage. As long as there is enough water and soluble carbohydrates, cow dung can be silaged together with other poultry and livestock manure and crop straw, forage or other roughage. When silaging, the best ratio of manure to forage or other feed is 1:1. Dingli Machinery tells you that this method can not only improve palatability and absorption rate, prevent excessive loss of protein, but also convert part of non-protein nitrogen into protein and kill almost all harmful microorganisms.
