Problems solved by technology

[0004] However, the traditional sweet potato storage room cannot accurately control the humidity, which makes the sweet potato easily moldy or even rotten during storage, making it inedible for humans or livestock, resulting in waste
Moreover, in the traditional sweet potato storage method, sweet potatoes are stacked together, which is not conducive to the discharge of carbon dioxide produced by sweet potato respiration, so it is prone to large areas of soft rot, which is not conducive to the preservation of sweet potatoes

Embodiment 2

[0044] On the basis of embodiment 1, in order to store the cleaned sweet potatoes more conveniently, the present embodiment is provided with a cleaning device 2 for cleaning sweet potatoes and a delivery device for transporting sweet potatoes after cleaning to sweet potato storage room 11; sweet potato storage room 11 is provided with the sweet potato inlet 14 that can be opened and closed toward cleaning device 2 side;

[0045] In this embodiment, the muddy sweet potatoes are placed in the cleaning device 2 for cleaning, and then transported by the conveying device 3 to the sweet potato storage room for storage. When the merchant needs to sell, it can be taken out without cleaning, which is more convenient.

Embodiment 3

[0047] The present embodiment uses the sweet potato storage room in Example 1 to provide a sweet potato storage method with simple operation, good fresh-keeping effect and low fresh-keeping cost, as follows:

[0048] Place mashed sweet potatoes in plastic baskets and store in a sweet potato storage room. Multiple plastic crates can be stacked on top of each other without damaging the sweet potato skin, and more sweet potatoes can be stored in the sweet potato storage room with better economic value. After placing the plastic basket filled with sweet potatoes in a good position, it can be treated at a temperature of 35°C to 38°C for 3 to 4 days. After the high-temperature healing is completed, the plastic basket filled with sweet potatoes must not be moved at will, so as not to damage the sweet potato skin and affect the storage time of sweet potatoes. After the sweet potato is treated with high temperature healing, the temperature in the sweet potato storage room can be contr...

Embodiment 4

[0050] On the basis of embodiment 1 and embodiment 3, the present embodiment provides a green and fresh-keeping sweet potato storage method, which sweet potato storage method comprises the following steps:

[0051] S01. In the sweet potato storage room, use mixed forage to smoke for 70 minutes. After the smoking is completed, spray potassium permanganate solution with a concentration of 0.1mol / L on the side wall, floor and top of the storage room. After spraying, close the sweet potato storage room. room for 110 minutes.

[0052] S02. After the sweet potato storage room is processed in step S01, technicians can coat the surrounding wall and the ground of the sweet potato storage room with photocatalyst, and turn on the light to continue to illuminate for 24 hours. At this time, the pretreatment of the sweet potato storage room is completed.

[0053] S03. Put the sweet potatoes with mud on the drying device to perform high-temperature healing treatment. During the high-temperat...
