Edible mushroom culture medium pretreatment device

The invention discloses an edible mushroom culture medium pretreatment device, and particularly relates to the field of culture medium pretreatment equipment, the edible mushroom culture medium pretreatment device comprises a preliminary crushing mechanism, a material conveyor and a flocculent dispersion mechanism, and the material conveyor works to convey materials treated by the preliminary crushing mechanism into the flocculent dispersion mechanism. By means of the scattering type treatment mode of the split type scattering assembly, the transmission connecting rod is used for driving the scattering frame to rotate, crushed materials gathered in the separation disc are subjected to scattering type treatment, blocky materials are flapped and extruded through the scattering frame so that the blocky materials can be loosened and crushed, the non-edged scattering frame acts on the crushed materials at the position of the separation disc, and the crushing efficiency is improved. The whole looseness is improved
