The invention relates to the field of manure recovery or treatment, in particular to a biological manure recovery device which comprises a crushing mechanism, a centrifugal mechanism, a drying mechanism, a pressing mechanism, a forming mechanism and a collecting mechanism. The centrifugal mechanism is used for centrifugal dewatering, dewatered materials are transferred to the centrifugal mechanism, the pressing mechanism comprises two matched extrusion rollers, the extrusion rollers are used for pressing the dried materials into strips and transferring the strip materials to the forming mechanism, the forming mechanism comprises two opposite forming rollers, the surface of each forming roller is provided with a die cavity, and the two forming rollers are mutually matched to extrude the materials. Manure is dried and solidified, so that the biological manure is recovered, pollution of the biological manure to rivers and water can be reduced, and manure recovery degradation speed is increased. The structure is convenient and simple, bio-fuels or feed can be rapidly manufactured, production can be facilitated, miniaturized manufacture can be realized, the biological manure recovery device is applicable to mini-plants or livestock farms, and cleanness and sanitation of workplaces can be ensured.
