Bio organic fertilizer equipment for raw material pretreatment:
including separation, crushing, moisture content and carbon nitrogen ratio adjustment.
Fermentation of bio organic fertilizer raw materials: the cycle generally takes 15-20 days.
The first stage: refers to the aerobic fermentation in the middle temperature and high temperature two stages of microbial metabolism. It refers to the whole process from the initial stage of fermentation, through medium temperature and high temperature, and then to the temperature began to decline, which generally takes 10-12 days.
The first stage: after the first stage of fermentation, there are still a part of the material that is easy to decompose and a large number of difficult to decompose organic matter, so it needs to continue fermentation to make it mature. At this time, the temperature continues to drop, when the temperature is stable at about 35-40 ℃, it reaches maturity, generally takes 5-10 days.
Post treatment: the post-treatment includes the removal of impurities and the necessary crushing treatment.
Advantages of bio organic fertilizer equipment in high temperature aerobic fermentation of organic fertilizer:
Bio high temperature aerobic fermentation process is a stabilization process: organic materials are transformed into humus rich in plant nutrients through aerobic microbial metabolism.
Bio high temperature aerobic fermentation process is a harmless process: microbial metabolism produces heat, which can keep the material temperature above 70 ℃ for about 7 days. It can kill pathogenic bacteria, parasite eggs and weed seeds.
Bio high temperature aerobic fermentation process will not inhibit plant growth: the aerobic rate of fully fermented products is less than 0.1 (09% / min) and will not burn seedlings when used in land. The moisture content of fermentation product is less than 40%, without Austrian gas, and has good adsorption property
Bio high temperature aerobic fermentation process can reduce the harm of toxic and harmful substances: heavy metal content through further biological treatment passivation, fully in line with the national agricultural standards.
