Since it is configured so that heat is exchanged by the reactor, the liquid to be treated coming through the inlet pipe recovers the heat of the liquid in the outlet pipe when it passes through the liquid heat exchanger and is heated. Since it enters the heating means, the driving energy of the heating means for performing heat sterilization can be reduced accordingly, and the running cost of the heat sterilizer can be reduced.
