What is the difference between aerobic fermentation and anaerobic fermentation of organic fertilizers? Organic fertilizer production includes two processes: fermentation and granulation. Fermentation is the most important process in the organic fertilizer production line, which is directly related to the final product quality of organic fertilizer. Organic fertilizers contain a lot of beneficial bacteria after being fermented and decomposed. What is the difference between aerobic fermentation and anaerobic fermentation of organic fertilizers?
Anaerobic fermentation
Anaerobic fermentation is a process in which organic fertilizers are decomposed in an anaerobic environment, and its main products are methane, carbon dioxide and many low molecular weight intermediates, such as organic acids. Compared with aerobic fermentation, anaerobic fermentation has less energy to degrade organic matter per unit mass, and anaerobic fermentation is generally prone to odor.For these reasons, current anaerobic fermentation is mainly used to support biogas projects. Anaerobic fermentation not only requires large investment in equipment, but also needs to deal with the use of biogas and biogas liquid. Therefore, most organic fertilizer manufacturers use aerobic fermentation process to prepare raw materials.
Aerobic fermentation
Aerobic fermentation is the process of decomposing organic matter in an aerobic environment, and its metabolites are mainly carbon dioxide and water. Aerobic fermentation is the process of mineralizing, decomposing and harmless fertilizers under the action of microorganisms. In the process of microbial decomposition of organic matter, not only a large amount of available nitrogen, phosphorus, potassium and other compounds that can be absorbed by plants are produced, but also a new polymer compound humus is produced, which is an important active substance that constitutes soil fertility. It is recommended to use a compost turning machine Improve quality and efficiency.
Compared with anaerobic fermentation, aerobic fermentation has the characteristics of low cost, strong biological activity, high fertility, and convenient promotion, which can achieve the purpose of deodorization and sterilization. Our organic fertilizer machine manufacturers, welcome to consult.
