[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A saffron filament air-drying device comprises an air-drying box, wherein a rotating component is arranged in the air-drying box, a net box with ventilation holes on the surface is arranged on the rotating component, ventilation ducts are arranged on the top wall and the bottom wall inside the air-drying box, ventilation slots are arranged on the side of the two ventilation ducts facing the net box, an exhaust fan is arranged at one end of the ventilation duct on the top wall, a hot air blower is arranged at the top outside of the air-drying box, an air inlet pipe is connected to the output end of the hot air blower, the air inlet pipe passes through the side wall of the air-drying box and is conductively connected to the ventilation duct on the bottom wall, an exhaust pipe is passed through the side wall of the air-drying box and the exhaust pipe is connected to the exhaust fan, and the exhaust pipe is conductively connected to the air inlet pipe.

[0008] Working principle:

[0009] Before air-drying the saffron filaments, first spread a layer of mesh cloth in the drying rack, then sprinkle some saffron filaments on it, then cover it with another layer of mesh cloth, and then sprinkle some saffron filaments on it. After repeating the mesh cloth covering several layers, the drying rack is placed in the air drying box.

[0010] The net box is then rotated, and the hot air blower is started at the same time. The output end of the hot air blower blows the hot air from the lower part of the air drying box upward to the net box through the air inlet pipe and the ventilation slots on the ventilation duct on the bottom wall, and the saffron filaments are dried through the air holes. The exhaust fan is started, and the exhaust fan draws the hot air from the lower part of the air drying box, so that the hot air flows from the lower part of the air drying box through the net box upward to the ventilation slots on the top ventilation duct and flows into the exhaust pipe. The hot air in the exhaust pipe enters the air drying box through the air inlet pipe, and flows to the net box again with the hot air blown out by the hot air blower, and the cycle is repeated.

[0011] Finally, take out the drying rack.

[0012] Beneficial effects:

[0013] In this solution, by providing an air drying box, a rotating assembly, a vent hole and a mesh box, the hot air in the air drying box enters the mesh box through the vent hole, and the rotating mesh box can drive the drying rack to rotate, so that the saffron filaments are heated more evenly, further enhancing the drying efficiency;

[0014] By arranging ventilation ducts, exhaust fans, hot air blowers and air inlet pipes on the top and bottom walls, the hot air blower is started when in use, and the output end of the hot air blower blows the hot air out from the lower part of the air drying box through the air inlet pipe and the ventilation slots on the ventilation ducts on the bottom wall. At the same time, the exhaust fan operates to extract the hot air at the bottom of the air drying box. Therefore, the hot air flows from the bottom of the air drying box through the mesh box to the ventilation slots on the top ventilation ducts, and enters the exhaust pipe, and then flows to the inside of the air drying box through the air inlet pipe again, so that the hot air is circulated and utilized repeatedly, reducing the energy consumption of the hot air blower; and this method allows the hot air to circulate from bottom to top, resulting in a more uniform temperature inside the air drying box, a better drying effect, and further improved drying efficiency.

[0023] In this scheme, by setting an air drying box 1, a rotating component, a vent 5 and a net box 2, the hot air in the air drying box 1 enters the net box 2 through the vent 5, and the rotating net box 2 can drive the drying rack 29 to rotate, so that the saffron filaments are heated more evenly, and the drying efficiency is further enhanced; by setting the ventilation ducts 3, the exhaust fan 4, the hot air blower 6 and the air inlet pipe 7 on the top wall and the bottom wall, the hot air blower 6 is started when in use, and the output end of the hot air blower 6 passes the hot air through the air inlet pipe 7 and the ventilation slots 28 on the ventilation duct 3 on the bottom wall from the air drying rack 29. The bottom of the box 1 is blown out, and at the same time, the exhaust fan 4 operates to extract the hot air at the bottom of the air-drying box 1. Therefore, the hot air flows from the bottom of the air-drying box 1 through the mesh box 2 to the ventilation slots 28 on the ventilation duct 3 at the top, and enters the exhaust pipe 8, and then flows to the inside of the air-drying box 1 through the air inlet pipe 7 again, so that the hot air cycle is repeatedly utilized, reducing the energy consumption of the hot air blower 6; and this method makes the hot air circulate from bottom to top, resulting in a more uniform temperature distribution inside the air-drying box 1, a better drying effect, and further improved drying efficiency.

[0026] By setting the second motor 11, the first rotating shaft 12, the first slider 13, the slide bar 14, the second slider 15 and the second rotating shaft 16, the operator starts the second motor 11, the net box 2 is moved out of the air-drying box 1, and then the drying rack 29 is placed in the net box 2, and the second motor 11 is started again to drive the net box 2 into the air-drying box 1, and after the drying is completed, the second motor 11 is started to move the net box 2 out of the air-drying box 1. This mechanized operation does not require the operator to manually pull the net box 2, which is easy to operate and improves the operator's loading and unloading efficiency.

[0027] like Figure 1 to Figure 3As shown, the net box 2 includes a box body 201 and a detachable box cover 202 disposed on the top of the box body 201. A positioning hole 17 is provided at the bottom of the box body 201. The positioning hole 17 is used to position and clamp the four positioning blocks 30 at the bottom of the drying rack 29. By providing the box body 201, the box cover 202 and the positioning holes 17, the box cover 202 is removed, and the four positioning blocks 30 at the bottom of the drying rack 29 are aligned with the positioning holes 17 and placed inside the box body 201, so that the drying rack 29 is positioned and placed, and the drying rack 29 is fixed.

[0031] Working principle:

[0032] Before drying the saffron filaments, a layer of mesh is first laid in the drying rack 29, and then some saffron filaments are sprinkled on it, and then another layer of mesh is covered, and then some saffron filaments are sprinkled on it. After the mesh is repeatedly covered with several layers, the second motor 11 is started, and the output end of the second motor 11 drives the first rotating shaft 12 to rotate, and the rotation of the first rotating shaft 12 drives the first sliding block 13 to slide, thereby driving the first motor 9, the mesh box 2 and the second sliding block 15 to slide out of the air drying box 1;

[0033] Then the operator opens the box cover 202, aligns the four positioning blocks 30 at the bottom of the drying rack 29 with the positioning holes 17 inside the box body 201; then the box cover 202 is closed, and the elastic block 18 is squeezed to squeeze the drying rack 29, and then the operator pushes the locking block 20 downward, and the first spring 22 pushes the first plug-in block 23 to move toward the plug-in slot 24, so that the box cover 202 is relatively locked with the box body 201;

[0034] If there is still a gap between the elastic block 18 and the drying rack 29 when the elastic block 18 is squeezed, the locking block 20 is pushed further, and the second spring 26 pushes the second plug-in block 27 to move toward the plug-in slot 24, so that the box cover 202 and the box body 201 are relatively locked;

[0035] Then start the second motor 11 again to drive the net box 2 to move into the air drying box 1; then start the first motor 9, the hot air blower 6 and the exhaust fan 4 respectively, the output end of the first motor 9 drives the transmission shaft 10 to rotate, and the rotation of the transmission shaft 10 drives the net box 2 to rotate; the output end of the hot air blower 6 blows the hot air out from the lower part of the air drying box 1 through the air inlet pipe 7 and the ventilation slots 28 on the ventilation duct 3 on the bottom wall, and at the same time the exhaust fan 4 operates to extract the hot air at the bottom of the air drying box 1, so that the hot air flows from the bottom of the air drying box 1 through the net box 2 to the ventilation slots 28 on the ventilation duct 3 at the top, and enters the exhaust pipe 8, and then flows to the inside of the air drying box 1 through the air inlet pipe 7 again, so that the hot air cycle is repeatedly utilized, and the hot air dries the saffron filaments in the drying rack 29 in a bottom-up manner.

[0036] Finally, the operator starts the second motor 11 to drive the net box 2 to move out of the air drying box 1, then removes the box cover 202 and takes the drying rack 29 out of the net box 2, and the whole operation is completed.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
