As a valuable resource, the storage and management of dried biogas residues have become an important link in the biogas production process. As a by-product of the development of biomass energy, the effective treatment and utilization of biogas residues are of great significance to reducing environmental pollution and promoting the circular economy. After the biogas residues are dried and dehydrated by the drying system, the moisture content of the biogas residues has dropped below 40%, becoming marketable green soil with sales conditions. However, due to the long duration of the production process, vehicles cannot always wait for loading, and the market demand is not continuous. In the absence of sales, a buffer warehouse is needed for storage, and when there is sales, the residues are exported and loaded by auger.
