Method of fermenting organic fertilizer in sheep manure organic fertilizer production line

 Technology of sheep manure fermenting organic fertilizer
The key processing step of organic fertilizer production line is fermentation process. Due to the different temperature in different places, the temperature in some areas is not high even throughout the year, which has a great impact on the fermentation time of organic fertilizer. The normal fermentation time is about 10 days. With the influence of different temperature in different areas, the whole fermentation cycle can be from 7 to 20 days.
The common method of sheep dung fermentation is trough fermentation, of course there are other methods. Trough fermentation is to use civil engineering to build a cement tank with a width of 3 meters and a length of 50 meters, and then install tracks on both sides of the wall, and the trough-type turning and throwing machine walks on the track to turn and throw the materials regularly. Put the sheep dung raw materials into the tank, generally the stack height is about 70 cm.
Then adjust the moisture of the raw materials. When the moisture is too high, add straw powder, rice husk and other organic plant residues. When the moisture is too small, pour into water or livestock and poultry urine. Adjust the moisture to 60%. Add organic fertilizer and start fermentation. Generally, 1kg of starter can ferment about 10t of raw materials.
In the fermentation process, trough compost turning machine is used to turn the pile once every two days, or turn and discard according to the temperature of the raw materials. Until the fermentation is complete.

Other processing processes of sheep manure after fermentation
In fact, after the sheep manure fermentation is completed, it will be regarded as organic fertilizer, but if we want to reach the standard of commercial organic fertilizer, we have to carry out the next step of processing. For organic fertilizer, the content of N, P and K should be 5% respectively, while the content of NPK in fermented organic fertilizer is not up to the standard of organic fertilizer, although it is rich in nutrients. It is necessary to use compost for granulation and add inorganic fertilizer in the process of granulation. Similarly, adding decomposed sheep manure compost in NPK fertilizer manufacturing process can greatly improve the fertilizer efficiency of finished products.
