Problems solved by technology

However, the agitation resistance of anaerobic dry fermentation is large, and the fluidity of the material is not good, so it is difficult to mix the fermentation raw material and the inoculum
Moreover, the viscosity of the material will also increase during the anaerobic dry fermentation process, resulting in poor fluidity and difficulty in discharging
Anaerobic fermentation needs to heat the material to a suitable temperature. Due to the low water content and poor thermal conductivity of the material, it is not easy to heat the material evenly during the anaerobic dry fermentation process.

Description

Technical field [0001] The present invention belongs to the field of agricultural organic waste resource technology, specifically relates to an agricultural organic waste fermentation system and method. Background [0002] China will produce a large number of agricultural organic waste every year, the use of agricultural waste anaerobic fermentation to produce biogas has the advantages of low cost, mature technology, high energy recovery rate, widely used in the resource utilization of agricultural waste. According to the total solids content of the fermentation substrate, anaerobic fermentation can be divided into anaerobic wet fermentation and anaerobic dry fermentation. However, the use of anaerobic wet fermentation technology to treat manure will produce a large amount of biogas slurry, which requires the consumption of a large amount of arable land, and improper application will also cause secondary pollution. [0003] Anaerobic dry fermentation makes up for the shortcoming...
