[0028] It should be noted that the air supply system 6 can also be arranged outside the shell 2, and the air outlet of the air supply system 6 penetrates the shell 2 and communicates with the gap layer. Arranging the air supply system 6 inside the shell 2 can avoid the air supply system 6 hindering the circulation of the gas in the gap layer.

[0030] Reference Figure 1 As a preferred mode, the auxiliary heating coil 7 is arranged in a circumferential direction inside the shell 2, which can further ensure that the temperature in the composting bin 1 is uniform.
