Shell comprising a cylindrical shape, shell with upward opening, a plurality of annular heating strips which are uniformly distributed in the axis direction of the shell are arranged on the inner wall of the shell; a layering plate located below the heating strips is arranged in the shell. A roller which can rotate around the axis of the shell and is provided with an upward opening is coaxially arranged in the shell. The roller is slightly lower than the shell, a plurality of liquid leakage holes are formed in the inner wall of the roller, a connecting column with the upper end extending into the roller is coaxially and fixedly connected to the bottom of the shell, and a plurality of stirring blades which are arranged in the circumferential di
