1.Adjust the water content of cow manure materials: the moisture content of fermented cattle manure and other animal manure should be controlled in 40 ~ 65. The following content shows the detailed water jugement process.
Water judgment: grasp a handful of cow dung, finger watermark but no water, the ground is scattered. Less water fermentation is slow, more water ventilation is poor, therefore, we must grasp the moisture content. If the moisture is too high, straw, sawdust, mushroom residue, dry soil powder can be added.
Water is suitable or not to judge the method: grasp a material, finger watermark but no water, the ground is scattered. The whole fermentation process can be completed after 5-7 days, such as deodorization, fermentation and sterilization.
2.Starting temperature of cattle manure organic fertilizer production: The starting temperature should be better than 15℃ (four seasons can work, not affected by the season, in winter as far as possible in indoor or greenhouse fermentation), fermentation temperature control in 70-75℃ below the appropriate.
3.Mixing ventilation: cow manure fermentation production of organic fertilizer is the need for good (consumption) oxygen fermentation, therefore, in the process of operation should increase the oxygen supply measures, so that mixing, frequent turn, ventilation is appropriate. Otherwise it will lead to anaerobic fermentation and odor, affecting the effect of fertilizer.
4.The completion of fermentation: In general, after 48 hours of cow dung accumulation, the temperature rises to 50 ~ 60℃, the third day can reach 65℃ above, in this high temperature by turning over once, under normal circumstances, the fermentation process will appear twice above 65℃, turning over twice can complete fermentation, fermentation can be completed within a week normally. The material was black and brown, and the temperature began to drop to normal temperature, indicating the completion of fermentation.
5.Small simple cow manure organic fertilizer production line cost: Within 100,000 yuan, for each customer configuration of organic fertilizer production line are different. Cow manure organic fertilizer production line low configuration only need mill, blender, granulator, screening machine and packaging machine. This is a basic configuration. You can add devices based on customer requirements. Therefore, the price of the whole cow manure organic fertilizer production line varies from tens of thousands to hundreds of thousands.
