[0023] Specific examples are given below.

[0024] See also Figure 1-5 As shown, a yam drying device includes a cabinet 11, a cabinet door 12 is installed on the side of the cabinet 11, and a hot air blower 14 is installed on the cabinet 11; a base 13 is provided inside the cabinet 11, a vertical shaft 22 is provided in the middle of the base 13, and a plurality of drying net frames are provided on the vertical shaft 22; an output end of the hot air blower 14 is fixedly connected to an air duct 15, and a plurality of drying tubes 16 are fixedly connected to the air duct 15, and the drying tubes 16 are arranged in an S shape, and the drying net frame is located between two drying tubes 16 close to each other, and the drying tubes 16 are provided with multiple groups of through holes; the drying net frame includes a frame 23, a bracket 24 and a porous net bag 25, the bracket 24 is fixedly connected to the vertical shaft 22, the bracket 24 and the frame 23 are fixedly connected, the porous net bag 25 is fixedly connected to the bottom of the frame 23, and a sleeve is fixedly connected to the middle of the porous net bag 25, and the vertical shaft 22 passes through the sleeve and is slidably connected thereto;

[0025] During use, the staff puts the yam slices into the frame 23, then closes the upper cabinet door 12, and then relies on the hot air blower 14 to inject hot air into the air guide duct 15, and then distributes it to multiple drying tubes 16. The hot air is ejected from the through holes on the drying tubes 16. The drying tubes 16 are located on the upper and lower sides of the frame 23 to blow hot air, so that the upper and lower sides of the yam slices can be dried, thereby improving the drying uniformity and drying effect of the yam slices.

[0026] Further, such as Figure 1-3 As shown, a pair of slide grooves 31 are provided at the bottom of the cabinet 11, and guide wheels 32 are rotatably connected to the bottom of the base 13 and the corresponding positions of the slide grooves 31. The bottom of the base 13 is fixedly connected to a motor 33, and the bottom end of the vertical shaft 22 is rotatably connected to the base 13, and the output end of the motor 33 is fixedly connected to the vertical shaft 22; when in use, the motor 33 can drive the vertical shaft 22 to rotate, and the vertical shaft 22 is connected to the frame 23 through the bracket 24, so that the frame 23 can be driven to rotate, and then the yam slices can be driven to rotate, thereby improving the uniformity of drying the yam slices, and the bottom drying guide wheels 32 of the base 13 slide inside the slide grooves 31 and can guide their movement. Relying on the above arrangement, the base 13 and the frame 23 can be pulled out from the inside of the cabinet 11, so that when taking and placing the yam slices, there is no hindrance from the drying tube 16, so it is convenient for the staff to take and place the yam slices.

[0027] Further, such as Figure 4-5 As shown, a fixing frame 41 is fixedly connected to the inner wall of the cabinet 11 and the corresponding position of the air duct 15, and a plurality of spring pieces 44 are fixedly connected to the inner wall of the bottom of the frame 23. The end of the spring piece 44 away from the frame 23 is fixed to the sleeve, and the bottom end of the sleeve is rotatably connected to a plurality of first pulleys 42, and the top of the fixing frame 41 is rotatably connected to the corresponding position of the first pulley 42 with a second pulley 43; when in use, the sleeve provided in the middle of the spring piece 44 will drive the sleeve to rotate during the rotation of the frame 23, and the first pulley 42 at the bottom of the sleeve will rotate during the rotation of the second pulley 43 above the fixing frame 41. , so as to squeeze the first pulley 42, and then the first pulley 42 and the sleeve can be moved downward, so that the center of the porous mesh bag 25 moves downward and becomes concave. After the first pulley 42 and the second pulley 43 are separated, the spring piece 44 is reset, so that the porous mesh bag 25 is shaken. Since the yam slices have a certain stickiness after ripening, they will adhere to the porous mesh bag 25 after drying. By shaking the porous mesh bag 25, the adhesion of the yam slices to the porous mesh bag 25 can be reduced. The motor 33 needs to be started after drying for half an hour to an hour to allow the surface of the yam slices to dry first, so as to reduce the shaking and adhesion of the porous mesh bag 25.

[0028] Further, such as Figure 5As shown, the end of the spring piece 44 away from the frame 23 is set in an upward curved shape, and the middle part of the porous mesh bag 25 is set in an upward convex shape; the fixing frame 41 is fixed with a support seat 51, and a support groove 52 is provided on the support seat 51 at a position corresponding to the vertical axis 22, and the vertical axis 22 is inserted into the support groove 52 and slidably cooperates with it; when in use, the spring piece 44 bends upward to support the upward protrusion of the porous mesh bag 25, thereby reducing the accumulation of yam slices in the middle, thereby reducing the adhesion of yam slices to the vertical axis 22. After the base 13 is pushed into the interior of the cabinet 11, its vertical axis 22 will be inserted into the support groove 52 of the support seat 51, thereby supporting the vertical axis 22, thereby improving the stability of the vertical axis 22.

[0029] Further, such as Figure 1 As shown, an extension plate 7 is fixedly connected to the bottom side wall of the cabinet 11.

[0030] Working principle: when in use, the staff puts the yam slices into the frame 23, then closes the upper cabinet door 12, and then relies on the hot air blower 14 to inject hot air into the air guide duct 15, and then distributes it to multiple drying tubes 16. The hot air is ejected from the through holes on the drying tubes 16. The drying tubes 16 are respectively located on the upper and lower sides of the frame 23 to blow hot air, so that the upper and lower sides of the yam slices can be dried, thereby improving the drying uniformity and drying effect of the yam slices. When in use, the motor 33 can drive the vertical shaft 22 to rotate, and the vertical shaft 22 is rotated through the bracket 24 and the frame 23. The drying guide wheel 32 at the bottom of the base 13 slides inside the slide groove 31 and can guide its movement. By relying on the above arrangement, the base 13 and the frame 23 can be pulled out from the inside of the cabinet 11. In this way, when taking and placing the yam slices, there is no hindrance from the drying tube 16. Therefore, it is convenient for the staff to take and place the yam slices. The sleeve provided in the middle of the spring 44 will drive the sleeve to rotate during the rotation of the frame 23. During the rotation of the first pulley 42 at the bottom of the sleeve, the second pulley 43 above the fixed frame 41 can squeeze the first pulley 42, and then the first pulley 42 and the sleeve can be moved downward, so that the center of the porous net bag 25 moves downward and is concave. After the first pulley 42 and the second pulley 43 are separated, the spring piece 44 is reset to make the porous net bag 25 shake. Since the yam slices have a certain stickiness after being ripened, they will adhere to the porous net bag 25 after drying. By relying on the shaking of the porous net bag 25, the adhesion of the yam slices to the porous net bag 25 can be reduced. On the porous mesh bag 25, the motor 33 needs to be started after drying for half an hour to an hour, so that the surface of the yam slices can be dried first, reducing the shaking and sticking of the porous mesh bag 25. When in use, the spring piece 44 is bent upward to support the upward protrusion of the porous mesh bag 25, thereby reducing the accumulation of yam slices in the middle, thereby reducing the adhesion of yam slices to the vertical axis 22. After the base 13 is pushed into the interior of the cabinet 11, its vertical axis 22 will be inserted into the support groove 52 of the support seat 51, so that the vertical axis 22 can be supported, thereby improving the stability of the vertical axis 22.
