[0044] The working process of the sweet potato post-harvest processing device provided in this embodiment is to place the sweet potatoes to be processed into the processing cabinet, and then input the control instructions of high-temperature saccharification and ozone preservation into the control system 300, and at the same time input the preset saccharification temperature value, preset saccharification time, preset ozone concentration value and preset ozone treatment time.

[0045] Then the control system 300 controls the hot air system 100 to heat the air in the processing cabinet. At the same time, the control system 300 collects the temperature value in the processing cabinet collected by the environmental monitoring system in real time. When the collected temperature value reaches the preset saccharification temperature value, the control system 300 starts timing. When the timing reaches the preset saccharification time, the control system 300 controls the hot air system 100 to stop working. At this time, high-temperature saccharification is completed.

[0046] When the temperature value collected by the control system 300 reaches room temperature, the ozone generating system 200 is controlled to release ozone into the processing cabinet. When the ozone concentration value detected by the environmental monitoring device and collected by the control system 300 reaches the preset ozone concentration value, the control system 300 starts timing. When the timing reaches the preset ozone treatment time, the control system 300 controls the ozone generating system 200 to stop working. At this time, the ozone preservation process is completed.

[0047] The sweet potato post-harvest processing device provided in the embodiment of the utility model can complete the high-temperature saccharification and ozone preservation processes of sweet potatoes through an integrated device, reducing the volume of the equipment, and also allowing the saccharified sweet potatoes to be stored for a longer period of time, avoiding the problem of sweet potatoes rotting due to long-term inability to be sold.
