1results about How to "Eliminate quality differences" patented technology

The present application relates to the related technical field of feed industry and livestock breeding, and discloses a combined solid-state fermentation device for postbiotic after solid-state fermentation, which comprises a combined fermentation tank including a first fermentation tank and a second fermentation tank, an inner tank body is arranged in the first fermentation tank, stirring blade devices, cleaning and crushing devices and air charging and extrusion assemblies are arranged in the inner tank body, driving motor assemblies are fixedly arranged above the stirring blade devices, and the driving motor assemblies provide rotating power for the stirring blade devices and the cleaning and crushing devices; the improved design of the present application realizes three-dimensional compound motion of rotation and up-down reciprocation by cooperation with bidirectional threaded rods, realizes synchronous motion by sharing a power source with the driving motor assemblies and the cleaning and crushing devices, and realizes the layout of X-shaped blades, inclined guide grooves and rough surface projections in the grooves, so that local fermentation dead angles of traditional equipment are completely eliminated, and product quality differences caused by uneven mixing are avoided.
