The organic fertilizer produced by cow manure contains a large amount of amino acids and organic matter, as well as nutrients such as nitrogen, phosphorus and potassium required for plant growth, which can improve the physical and chemical properties of the soil and improve the continuous production capacity of the soil. The use of manure waste from breeding cattle to produce biofertilizer and organic fertilizers for resource utilization has broad application prospects.
According to the difference of organic matter content, total nutrient, water content and pH value of organic fertilizer, organic fertilizer can be divided into refined organic fertilizer, organic compound fertilizer and biofertilizer. Organic fertilizer manufacturing process is different, the final commercial fertilizer products are different. So how to use cow dung to produce high value organic fertilizer products?
The dehydrated cow dung is spread out on the hardened ground of the cement. If the water is more than 60%, the cow dung should be air-dried until the moisture is reduced to about 55%, and the pH is adjusted by adding lime powder. Then, the cow dung is composted according to 70% of the cow dung and 30% of the auxiliary material, and the compost material is added to the fermenting strain and various auxiliary materials.
Organic Fertilizer Manufacturing Process Equipment
Fermented compost can be manufactured into different commercial fertilizers through organic fertilizer manufacturing process equipment. The main equipments of organic fertilizer production process are crusher, mixer, organic fertilizer granulator, rotary drum dryer, drum cooler and fertilizer packing machine.
Compared with the production of organic fertilizers, the production of biofertilizer should pay attention to the ratio of fertilizers. First, balance the amount of organic fertilizers added with various inorganic fertilizers such as nitrogen, phosphorus and potassium, and add biological bacteria. Then all crushed raw materials should be evenly added to the organic fertilizer granulator.
The granulation rate of organic fertilizer granulator is high, and the size of particle diameter can be adjusted properly by mixing amount of material and spindle speed. The fertilizer granulator is suitable for granulating chicken manure, pig manure, cow manure, peat and other materials.
