[0024] Existing stirring and foaming equipment is usually designed with a central stirring paddle 5, which causes insufficient stirring of materials at the edge, and due to gravity, it is difficult to stir the materials at the bottom sufficiently. Considering these problems, a stirring and foaming equipment that can stir more sufficiently is designed.

[0025] The heating plate 2 includes two semicircular arc structures, one side of the semicircular arc structure located on the same side is hinged to the side wall of the mixing barrel 1, and the other side of the semicircular arc structure is provided with a connecting structure for fixing the two heating plates 2.

[0026] When the two heating plates 2 are closed, a ring structure can be formed, surrounding the outer wall of the mixing barrel 1. When rapid cooling is required or the heating plate 2 fails, the two heating plates 2 can be unfolded outward, so that the heating plates 2 and the mixing barrel 1 can dissipate heat quickly at the same time. The unfolded heating plate 2 makes it more convenient for the staff to access the internal components of the heating plate 2.

[0027] In this embodiment, the connection structure can adopt a snap-on connection structure to facilitate the fixation and deployment of the two heating plates 2. On the other side opposite to the connection structure, a rotating shaft is provided on the heating plate 2, and both ends of the rotating shaft are screwed to the outer wall of the mixing barrel 1.

[0028] A heat insulation layer 201 is built into the outwardly facing plate surface of the heating plate 2 .
