The invention provides circulating production technology for processing an organic fertilizer from faeces and remains. The technology comprises a step 1 of loading, in which materials are put to a loading area in a hand-operated or automatic manner; a step 2 of fermentation and granulation, in which a rotary blade device is adopted and circularly operates along a fermenting tank while the materials operates in a direction opposite to the device along the fermenting tank, and the moisture of the materials is gradually reduced from 50-80% to 30% and forms a granular organic fertilizer in a production cycle of 5-30 days, thereby achieving fermentation and granulation of the materials; and a step 3 of discharging, in which the fermented and granulated organic fertilizer is output in a hand-operated or automatic manner. Circulating production technology and the fermenting tank are adopted, the service efficiency of the device is increased, and the processing capacity of the device is improved. The technology is simple in process, the operation cost is reduced, and the failure rate of the device is reduced.
