Continuous aerobic dynamic composting is a dynamic secondary fermentation technology with shorter fermentation time. In the composting of organic fertilizer production line
, continuous feeding and continuous discharging are adopted. In a specially designed fermentation device, the materials are kept in a continuous dynamic state. It is easy to make the components mix evenly and form a gap, which is conducive to ventilation, rapid evaporation of water and shortening the fermentation cycle.
Overview of continuous aerobic dynamic composting process
Aerobic composting process includes three basic steps: pretreatment of solid waste, aerobic decomposition of organic components and preparation of compost products. Aerobic fermentation of organic fertilizer production process
is mainly divided into aerobic static composting and aerobic dynamic composting. Continuous aerobic dynamic composting is one of the methods of aerobic dynamic composting. Compared with other processes, continuous aerobic dynamic composting process is a dynamic secondary fermentation technology with shorter fermentation time. The continuous feeding and discharging mode is adopted in the process, which makes the fermentation cycle shorter.
Characteristics of continuous aerobic dynamic composting process
The characteristic of continuous aerobic dynamic composting process is that the materials are kept continuously, which makes the uniformity and acceleration of organic components, moisture, temperature and oxygen supply, etc. to a great extent. This directly creates conditions for mass transfer and heat transfer, improves the degradation rate of organic matter, shortens the fermentation cycle, and makes the whole process completed ahead of time. This is very important for saving engineering and processing capacity.
