The invention discloses a stirring machine which includes a cooling water shell, and also includes a stainless steel cup, a cup base, a stirring paddle, a driving device, an upper shell assembly, a temperature control panel, and a temperature probe. The driving device is fixedly installed in the upper shell assembly. The stirring paddle, which rotates synchronously with the driving device, is connected to the lower end of the driving device. The stirring paddle includes a stirring shaft. An anchor-type stirring paddle is arranged on the lower end of the stirring shaft. A first axial-flow-type stirring paddle is disposed on the position, which is adjacent to the upper part of the anchor-type stirring paddle, of the stirring shaft. A second axial-flow-type stirring paddle is disposed on the position, which is adjacent to the upper part of the first axial-flow-type stirring paddle, of the stirring shaft. A round projection is formed on the lower end of the stainless steel cup. A round elastic groove, which is insertedly matched with the round projection, is disposed on the bottom of the cooling water shell. The cooling water shell is externally connected to a circulating cooling water system. The stirring machine has simple structure, is convenient and energy-saving, is safe and sanitary to use, and can improve the stirring and mixing efficiency of materials under the flow direction effects generated by the stirring paddles in different structures, thereby reducing energy consumption.
