Difficult to apply. Rural domestic waste is dominated by organic components, and the use of composting technology to treat rural domestic waste has a relatively obvious degree of harmlessness and reduction. At the same time, it can maximize the resource utilization of waste treatment. Composting and its products have been proven to have many benefits. It can increase soil nutrients, prevent soil erosion, increase soil moisture content, inhibit pests, improve soil fertilizer efficiency and biodiversity, and improve crop quality and yield.

The composting device is a necessary equipment for composting. At present, the composting device mostly adopts the intermittent composting method. The composting cycle is long, the processing capacity is small, and the composting temperature is difficult to maintain. This has become the reason why the composting device is difficult to be widely used.

In view of the problems existing in the composting temperature, cycle, and processing capacity of the existing devices, it is necessary to design a more efficient and reasonable composting device.
