Sheep manure is a good raw material for organic fertilizer processing, and it contains high nutrient content and properties for crops and soil: sheep manure contains 65.5% water, 31.4% organic matter, 0.65% nitrogen, 0.47% phosphorus, and 0.23% potassium. Sheep manure has a fine and dry texture, rich in nutrients, and is a type of “hot fertilizer”. It is often mixed and piled up with pig and cow manure with high moisture content to improve the quality of pig and cow manure.
Fermentation granulation process of sheep manure organic fertilizer production line:
1. Mix sheep manure with an appropriate amount of straw powder, and the amount to be added depends on the moisture content of the sheep manure. Generally, fermentation requires a moisture content of 45%, which means kneading it into a ball with your hands, seeing water between your fingers, but not dripping. Release your hand and dissolve it immediately. Then add corn flour and bacterial strains. The function of corn flour is to increase sugar content for bacterial fermentation, allowing multi-dimensional complex enzyme bacteria to quickly gain an advantage.
2. Add the prepared mixture to the organic fertilizer mixer for stirring, making sure to mix evenly, thoroughly, and without leaving any clumps.
3. The mixed ingredients are stacked into long strips with a width of 1.5-2 meters and a height of 0.8-1 meters, and flipped with an organic fertilizer flipper every 2 days.
4. Piling takes 2 days to heat up, 4 days to have no odor, 7 days to loosen, 9 days to become fragrant, and 10 days to become fertilizer. On the second day of stacking, the temperature can reach 60 ℃ -80 ℃, killing diseases and pests such as Escherichia coli and insect eggs; On the fourth day, the odor of sheep manure was eliminated; On the 7th day, the compost became loose and dry, covered with white mycelium; On the 9th day, it emits a fragrance of koji; On the 10th day, the bacterial fertilizer will ferment and mature;
5. After slightly drying, it can be crushed by a semi wet material crusher, granulated by an organic fertilizer granulator, dried and dehydrated by a dryer, and then screened by a screening machine. The finished organic fertilizer is ready and can be packaged and stored
As one of the relatively large poultry industries in China, the utilization value of sheep manure is constantly being applied to crops, and the production of organic fertilizer is constantly increasing every year.
