Mixing, heating and drying machine for bone residue processing

The utility model discloses a mixed heating dryer for bone residue processing, and relates to the technical field of bone residue drying. In order to solve the problems that according to an existing bone residue dryer, bone residues need to be heated in a hot-blast stove before being dried and then enter the dryer, dust removal is conducted after drying is completed, work efficiency is low, and production efficiency cannot be improved easily. A mixing and heating dryer for bone residue processing comprises a drying roller, a feeding port is formed in the upper surface of the drying roller, a rotary heating mechanism is arranged in the drying roller, a frequency converter is installed on the outer wall of the drying roller, a discharging mechanism is arranged on the right side of the drying roller, and a dust suction mechanism is installed on the discharging mechanism. A grate plate is fixedly installed on the inner wall of the drying roller. According to the mixing and heating dryer for bone residue processin
