If it does in this way, not only the warm water in the warm water disinfection tank 103 can be heated uniformly and quickly by the heat exchange method, but also a highly accurate heating adjustment by the proportional control valve becomes possible. In addition, in the present embodiment, as shown in FIG. 17, since the helical fins 110 a are formed in the heat exchange pipe 110, the surface area of the heat exchange pipe 110 can be increased and the heat exchange efficiency can be increased.

  Moreover, the hot water disinfection apparatus 101 is provided with a control panel 111 for controlling each part. The control panel 111 automatically detects the temperature of each of the tanks 103 and 104 and automatically controls the warm water heating means so that the temperature of each of the tanks 103 and 104 is maintained at a predetermined temperature. The control panel 111 includes temperature history storage means for storing the temperature of each of the tanks 103 and 104 every predetermined time. If it does in this way, when the germination defect arises in the seed potato which sterilized with warm water with this apparatus, the cause can be pinpointed with reference to temperature history.
