[0027] The drying box 10 has a low-temperature drying cavity and a high-temperature drying cavity, two cabinet doors are hinged to the front wall of the drying box 10 for sealing the two cavities, in the drying process of squid, the squid needs to be heated first to remove moisture, and then the low-temperature drying method is used to retain the original characteristics and taste of the protein, the high-temperature drying cavity is fixedly provided with an electric heating rod and a temperature sensor, the low-temperature drying cavity is provided with a temperature sensor, and the electric heating rod and the temperature sensor are connected with a controller, so that the temperature of the cavity of the drying box 10 can be controlled and monitored to control the drying process.

[0028] As shown in Figure 3 , Figure 4 and Figure 5As shown, the air supply structure, located at the top of the drying chamber 10, supplies air to the low-temperature drying chamber and the high-temperature drying chamber. The air supply structure includes an air box 20, a first fan 21, a second fan 22, an insulation plate 23, and a cooling plate 24. The air box 20 is fixedly connected to the drying chamber 10, the insulation plate 23 is fixedly connected to the air box 20, and the cooling plate 24 is rotatably connected to the insulation plate 23. The cold end and hot end of the cooling plate 24 are located on opposite sides of the insulation plate 23. The first fan 21 and the second fan 22 are fixedly installed on opposite sides of the air box 20. The first fan 21 is connected to the low-temperature drying chamber of the drying chamber 10, and the second fan 22 is connected to... The high-temperature drying chamber of the drying oven 10 is connected, and the air box 20 forms a rectangular box. The insulation plate 23 is at the same height as the chamber of the air box 20. The insulation plate 23 divides the chamber of the air box 20 into two parts. The cooling plate 24 includes a circular partition and a cooling plate fixedly installed on one side of the partition. A circular window is opened at the center of the insulation plate 23. The cooling plate 24 is installed in the circular window. A motor 25 is fixedly installed on the outside of the air box 20.

[0029] In this scheme, the main operation is achieved through the cooling plate 24. The cooling element of the cooling plate 24 can be a semiconductor cooling element. The fins at the cold end of the cooling element are used to cool the gas and deliver low-temperature cold air to the low-temperature drying chamber, so that the squid dries in a low-temperature environment. The heat generated at the hot end of the cooling element is sent to the high-temperature drying chamber of the drying box 10 by the second fan 22 to preheat the squid with high humidity. This avoids the squid's protein denaturation caused by the heating rod heating up too quickly, which would affect the taste. The cooling plate 24 can be used for both cold and hot ends to reduce losses and lower energy consumption.
