The device can automatically cut the larger domestic garbage in the crushing barrel 16 through the crushing knife 20 and put it into the processing box 1 for fermentation. The liquid pump 4 extracts the biological fermentation solution to spray the domestic garbage repeatedly, which can greatly improve the fermentation speed. After the fermentation is completed, it is quickly squeezed and dehydrated through the squeezing plate 13, which is simple, fast, time-saving and labor-saving. ;
