The overturning stirring can promote the convection movement of the solid raw materials in the stirring barrel 1, so that the solid raw materials at different levels can exchange positions with each other, further improving the mixing uniformity. Through the built-in hot air blowing heating mode, since the hot air blower directly acts on the interior of the stirring barrel 1, the heat can be transmitted to the solid raw materials more quickly, reducing the loss of heat in the transmission process, which helps to improve the heating efficiency, and the built-in hot air blower can more directly affect each corner in the stirring barrel 1, so that the temperature distribution is more uniform.
