The ozone generator 8 and the negative ion generator 9 are conducive to the generation of ozone to sterilize the sweet potatoes and reduce the influence of sweet potato pathogens on the storage quality of the sweet potatoes. The double-layer box setting of the sterilization box 4 and the inner box 7 can enable the double-layer barrier curtain 11 to block ozone and thereby reduce the escape of ozone from the inner box 7.

[0021] like Figure 3As shown, the interior of the drying box 3 is provided with a heating and drying assembly 6, which includes a heating box 601, a heating layer 602 and a supply fan 603. The heating layer 602 is provided on the upper side of the interior of the heating box 601, and the supply fan 603 is evenly installed below the heating box 601; the heating and drying assembly 6 also includes an air inlet cavity 604 and a vent pipe 605, the outer sides of both sides of the heating box 601 are connected to the air inlet cavity 604, and the lower side of the air inlet cavity 604 is connected to the vent pipe 605; the vent pipe 605 is connected to the interior of the drying box 3, A filter is fixed at the pipe opening of the ventilation pipe 605 near the side of the drying box 3; the heating layer 602 is equipped with a heating wire to heat the gas entering the heating box 601 and control the heating temperature. The air supply fan 603 is used to send the hot air flow into the drying box 3 so as to properly dry the sweet potatoes in the drying box 3 to avoid the sweet potatoes carrying water droplets and causing rotting and deterioration during storage. The ventilation pipe 605 and the air inlet cavity 604 can return the airflow inside the drying box 3 to the inside of the drying box 3 for circulation heating.

[0022] like Figure 2 As shown, opening adjustment components 12 are installed on the inner sides of both sides of the sterilization box 4, and the opening adjustment components 12 include an electric telescopic rod 1201, a lifting plate 1202 and a baffle 1203.

In addition, the air curtain machine 1204 can generate airflow to block the inlet and outlet port 5 of the sterilization box 4, thereby further preventing ozone from escaping.

[0023] In summary, if Figure 1-Figure 3As shown, the sweet potato storage pretreatment equipment, when in use, can firstly feed the sweet potatoes through the feeding belt 2, so that the sweet potatoes pass through the drying box 3 and the sterilizing box 4 in turn and stay for a period of time. When the sweet potatoes are in the drying box 3, the heating layer 602 is equipped with a heating wire to heat the gas in the heating box 601 and control the heating temperature. Then, the hot air flow is sent into the drying box 3 by the supply fan 603, so as to properly dry the sweet potatoes in the drying box 3 to avoid the situation that the sweet potatoes carry water droplets and cause rot and deterioration during storage. In addition, the ventilation pipe 605 and the air inlet cavity 604 can return the air flow in the drying box 3 to the inside of the drying box 3 for circulation heating.
