NOVELTY - Fermenting dry manure using a device comprises adopting atmospheric aerobic fermentation device for solid aerobic fermentation by using guillotine chopped dry straw, fermented dry organic fertilizer or other dry organic materials as moisture absorption material and mixing with excrement, or sprinkling them directly on livestock excrement or toilet pit to absorb too much moisture in excrement, and fermenting; stopping fermentation, removing the cooked material and stacking on a workshop, if the moisture content is 15%, directly using it as a fertilizer.    USE - The method is useful for fermenting dry manure using a device (claimed).    ADVANTAGE - The method not only ferments the manure, but also ferments high agro-processing residues, diseased fruit, rotten leaves, weeds and biomass waste (claimed).    DETAILED DESCRIPTION - Fermenting dry manure using a device comprises adopting atmospheric aerobic fermentation device for solid aerobic fermentation by (i) using guillotine chopped dry straw, fermented dry organic fertilizer or other dry organic materials as moisture absorption material and mixing with excrement in presence/absence of organic material decomposition agent, or sprinkling them directly on livestock excrement or toilet pit to absorb too much moisture in excrement, then adjusting the water content of the mixture to 30-50%, and placing the mixture in a fermentation device for fermenting; where the fermentation device includes moisture insulating screen frame box, moisture insulating screen frame box fleet, and fermentation chamber, and the fermentation device is placed in open air or fermentation room for fermenting; and the fermentation environment or fermentation room environmental conditions include temperature of 16 degrees C, humidity of below 60%, and easy ventilation; (ii) when the fermentation temperature increases to 55 degrees C, dropping to below 35 degrees C, then stopping fermentation, removing the cooked material and stacking on a workshop, if the moisture content is 15%, directly using it as a fertilizer; or using the fermented dry manure as absorbent material and sprinkling them directly on livestock excrement or toilet pit to adjust the moisture content in excrement; or sieving and screening to obtain powder and granular slag, and using as fertilizer and moisture absorbent material or as raw material for further processing.
