when the temperature of the slurry is detected to be equal to the boiling point temperature Tf, the heating is stopped, and the pulping process is stopped.
In the exemplary embodiment of the invention, as the temperature of the slurry rises, the slurry foam rises rapidly in the process of approaching the boiling point, if the slurry is heated by adopting higher power, overflow is difficult to control under the action of thermal inertia, so the heating power is reduced by stepwise decreasing, the absorption of heat in unit time is reduced, the rising speed of the slurry foam is indirectly reduced, thereby reducing the risk of overflow, the temperature of the slurry is slowly and stably in the process of approaching the boiling point by combining with the intermittent working mode of the motor, and simultaneously, the pulping period is shortened to the greatest extent due to the stepwise decreasing of the heating power along with the rise of the temperature of the slurry.

2) judging whether the temperature of the slurry is higher than the boiling point temperature Tf-4 ℃ or not, and if so, exiting the process; and if not, performing fault alarm prompting.
In the exemplary embodiment of the invention, the problem that the pulping process cannot be finished due to the fact that the pulping process cannot be exited after being heated for a long time is prevented by limiting the working time of the pulping process, and meanwhile, the boiling degree can be fully ensured and the drinking safety of a user can be ensured by judging whether the temperature of the pulp reaches the boiling point temperature Tf-4 ℃ or not and only generally, if the temperature of the pulp is higher than the temperature.
