[0035] like Figure 1 、 Figure 2 、 Figure 3and Figure 4 The embodiment of the present invention is shown in Figure 1. Provided is a constant temperature drying box for steamed rice production, comprising a box body 1 and a hot air blower 12. The interior of the box body 1 is arranged in an arc shape, and the box body 1 converges toward the lower interior. A flip assembly 2 is provided on the box body 1. A box cover 3 is threadedly connected to the upper surface of the box body 1. A vertical pipe 6 is passed through the box cover 3. The lower end of the vertical pipe 6 is connected to an air plate 16. There are two groups of air plates 16. A connecting pipe 15 is connected between the two groups of air plates 16. A plurality of groups of evenly distributed air holes are provided on the lower surface of the air plate 16. A discharge pipe 13 is connected to the middle position of the lower part of the box body 1. A valve 14 is provided on the discharge pipe 13. A feed pipe 4 is installed in the middle position of the upper surface of the box cover 3. A pipe cover 5 is movably engaged with the upper end of the feed pipe 4. The upper end of the vertical pipe 6 is connected to a telescopic hose 7. The telescopic hose 7 is connected to a connecting pipe 8. The other end of the connecting pipe 8 is connected to a filter box 9. The filter box 9 is movably equipped with a first filter screen 10 and a second filter screen 11, and the first filter screen 10 is close to the connecting pipe The hot air dries the rice inside the box 1 and the turning component 2 is started synchronously when the hot air blower 12 is started.

[0036] like Figures 1 to 5 As shown, the flipping component 2 includes a motor 201, which is fixedly installed in the middle position of the side of the box body 1, and a threaded hole 205 is provided at the output end of the motor 201. The flipping component 2 also includes a rotating rod 203, and multiple groups of stirring blades 204 are installed on the outside of the rotating rod 203. A threaded hole 205 is provided at one end of the rotating rod 203, and the threaded hole 205 is threaded with a bolt 206. The bolt 206 is threaded with a connecting piece 202, and the connecting piece 202 is semicircular. The connecting piece 202 connects the motor 201 and the rotating rod 203. Start the motor 201, the motor 201 starts to drive the connecting piece 202 and the bolt 206 to rotate, the connecting piece 202 and the bolt 206 rotate to drive the rotating rod 203 to rotate, the rotating rod 203 rotates to drive the stirring blade 204 to rotate, and the stirring blade 204 rotates to drive the rice to flip, so that the rice can be evenly contacted with the hot air.

[0037] The working principle of the technical solution provided by the utility model is as follows:

[0038] When the parboiled rice is actually dried, the parameters of the hot air blower 12 are adjusted, and after the steamed rice is preliminarily dried and cooled, it is passed into the interior of the box 1 through the feed pipe 4, and then the pipe cover 5 is covered. At this time, the hot air blower 12 is started, and the hot air blower 12 is started to draw air into the interior of the hot air blower 12, and the hot air blower 12 heats the air. The heated air enters the filter box 9, and is filtered under the action of the first filter screen 10 and the second filter screen 11 (the first filter screen 10 filters fine particles and absorbs water, that is, fine filtration, and the second filter screen 11 filters larger particles, that is, coarse filtration). The filtered hot air then enters the connecting pipe 8, the telescopic hose 7, and the vertical pipe 6, and then the hot air enters the wind plate 16 and the connecting pipe 15. Finally, the hot air dries the rice inside the box 1. The arrangement of the filter box 9, the first filter screen 10, and the second filter screen 11 achieves air filtration, thereby preventing dust and debris in the air from adhering to the surface of the rice and preventing the rice from being contaminated.

[0039] When the hot air blower 12 is started, the turning component 2 is started synchronously, specifically the motor 201 is started. The motor 201 starts to drive the connecting piece 202 and the bolt 206 to rotate. The connecting piece 202 and the bolt 206 rotate to drive the rotating rod 203 to rotate. The rotating rod 203 rotates to drive the stirring piece 204 to rotate. The stirring piece 204 rotates to drive the rice to turn, so that the rice can be evenly contacted with the hot air. Through the setting of the turning component 2, the turning of the rice is achieved, which can ensure the drying effect of the rice in the lower part of the box 1, so that the rice is fully dried, and the drying efficiency of the steamed rice is improved. In addition, through the setting of the connecting piece 202, if the stirring piece 204 falls after working for a long time, the rotating rod 203 is convenient to disassemble and replace.

[0040] When drying rice, when there is more water vapor, open the pipe cover 5 to allow the water vapor to enter the air upward. After the rice is dried, open the valve 14 to allow the rice to fall.

[0041] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
