[0003] When the reactor is processing raw materials, its temperature control is an important operating parameter. When the material inside the reactor is heated, the inside of the reactor is heated directly through a heat-conducting medium inside the temperature chamber outside the reactor.

Since the heating wire is arranged at a fixed point inside the temperature chamber, when heating, the heating wire can only heat the surrounding area first, and then slowly transfer the temperature to the entire temperature chamber. The whole process is relatively slow. Therefore, the temperature inside the temperature chamber is in an uneven condition for a long time, which will affect the heating of the material inside the reactor. It is necessary to improve the heating structure inside the temperature chamber. Summary of the invention
