[0018] Embodiment 1

[0019] like Figures 1 to 3 As shown, a hot air drying device proposed in the utility model includes a drying box 1 and a drying mechanism; a box door 103 is arranged above the front end of the drying box 1, and a material taking port 101 is arranged below the box door 103; the drying mechanism is arranged inside the drying box 1, and a waste box 4 and a material receiving box 6 are arranged in sequence below the drying mechanism, and the waste box 4 and the material receiving box 6 are both slidably connected to the inner wall of the drying box 1 and adapted to the material taking port 101.

[0020] The drying mechanism includes a drying cage 2, a transverse pipe 3 and a diverter pipe 301. The drying cage 2 is arranged inside the drying box 1 and is driven to rotate by a motor installed on the outer wall of the drying box 1. An electric door 201 is arranged on the drying cage 2; the transverse pipe 3 is installed on the top of the inner wall of the drying box 1 through a mounting piece, and an air inlet valve 302 is connected to the input end of the transverse pipe 3. The top of the air inlet valve 302 extends to the outside of the top of the drying box 1 and is connected to a hot air supply component; a plurality of groups of diverter pipes 301 are arranged, and the plurality of groups of diverter pipes 301 are evenly installed at the bottom of the transverse pipe 3, and a plurality of groups of air outlets 303 are arranged on the diverter pipe 301.

[0021] Further, the inner wall of the drying box 1 is provided with a limit rail 104, and the waste box 4 or the receiving box 6 is slidably connected to the limit rail 104. The waste box 4 and the receiving box 6 are provided with a handle, and the handle is convenient for sliding the waste box 4 or the receiving box 6 along the limit rail 104 to be pulled out or pushed in.

[0022] Furthermore, the shunt pipe 301 is set to be arc-shaped, and the shunt pipe 301 is adapted to the outer circumference of the drying cage 2, and the distances between the multiple groups of air outlets 303 and the outer circumference of the drying cage 2 are consistent. The hot air ejected from the air outlet 303 is lifted to be more uniform in the drying cage 2, so that the dried sweet potatoes inside the drying cage 2 are evenly heated.

[0023] Furthermore, the drying cage 2 is set to be cylindrical and sealed at both ends. The width of the waste box 4 and the receiving box 6 is greater than the width of the drying cage 2 to prevent impurities or dried sweet potatoes in the drying cage 2 from scattering, making it easier to accurately receive the materials.

[0024] In this embodiment, the box door 103 and the electric door 201 are opened, the sweet potato slices are placed in the drying cage 2 and the electric door 201 and the box door 103 are closed. The drying cage 2 is driven by a motor to rotate at a uniform speed, thereby driving the sweet potato slices inside the drying cage 2 to flip over. At the same time, hot air is transported to the air inlet valve 302 through an external hot air supply component, and the hot air enters each group of diversion pipes 301 through the horizontal pipe 3, and then sprayed toward the inside of the drying cage 2 through multiple groups of air outlets 303. As the sweet potato slices flip over, they can be evenly dried, and the drying exhaust gas is discharged from the heat dissipation holes at the top of the drying box 1. During the flipping process, impurities such as broken sweet potato chips will pass through the mesh holes on the drying cage 2 and fall into the waste box 4. The waste box 4 can be pulled out from the inside of the drying box 1 to clean up the impurities. After drying, the electric door 201 is opened to allow the sweet potato chips inside the drying cage 2 to fall into the receiving box 6, which can be pulled out for collection.

[0025] Embodiment 2

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, a hot air drying type drying device proposed by the utility model, compared with the first embodiment, a cleaning mechanism compatible with the drying cage 2 is arranged inside the drying box 1, and the cleaning mechanism includes a driving assembly, an electric push rod 502 and an arc brush 504; the driving assembly is arranged on the inner wall of the drying box 1; the electric push rod 502 is driven by the driving assembly to reciprocate along the width direction of the drying cage 2; an elastic rod 503 is installed at the output end of the electric push rod 502, and the elastic rod 503 is composed of a telescopic rod and a spring sleeved on the outside thereof, which is convenient for self-adjustment to avoid damage caused by a large abutment force between the arc brush 504 and the drying cage 2; the arc brush 504 is installed on the elastic rod 503, and a side wall of the arc brush 504 is provided with a brush and a plurality of water outlet holes, and the plurality of water outlet holes are distributed between the brushes, and the other side wall is connected to a water inlet valve 505 through a water pipe, and the other end of the water inlet valve 505 extends to the outside of the top of the drying box 1 and is connected to an external water supply assembly.

[0027] Furthermore, the driving assembly is composed of a screw 5 rotatably connected to the inner wall of the drying box 1 and a movable seat 501 threadedly sleeved on the outside of the screw 5. The screw 5 is driven to rotate by a motor installed on the outer wall of the drying box 1. A slide groove 102 is provided on the inner wall of the drying box 1. The top of the movable seat 501 is slidably connected to the slide groove 102. The setting of the slide groove 102 is convenient for limiting the movement trajectory of the movable seat 501, so that it can reciprocate in a stable horizontal direction along the screw 5 without rotating on its own.

[0028] In this embodiment, after the dried sweet potatoes are discharged, the waste box 4 is rinsed and pushed into the drying box 1. The motor drives the screw 5 to rotate and then drives the movable seat 501 to reciprocate horizontally. At the same time, the output end of the electric push rod 502 drives the arc brush 504 to approach the drying cage 2, and water is transported to the water inlet valve 505 through the external water supply component. The water enters the arc brush 504 along the water pipe and is discharged from multiple groups of water outlet holes. Then the arc brush 504 reciprocates horizontally along the outer circumference of the drying cage 2 to wash it. The outer circumference of the drying cage 2 can be fully cleaned by the rotation of the drying cage 2 to avoid interference with subsequent use. The cleaning waste water is received by the waste box 4 and can be discharged through the drain valve 401 on the side wall of the waste box 4. After the waste water is discharged, the waste box 4 is extracted again to clean the solid impurities.

[0029] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
