Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice drying technology, specifically a device for drying the moisture content of rice. Background Technology
[0002] Rice drying is the process of reducing the moisture content of harvested rice to safe storage standards using specific drying equipment and techniques. This process is crucial for ensuring rice quality, extending storage time, and improving grain processing efficiency.
[0003] Current rice drying methods often employ dryers, which use hot air to dry the rice. However, in current dryers, hot air is only blown into the drying chamber from one side, and the rice inside the chamber cannot move. This results in uneven heating of the rice, which increases drying time and reduces efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a device for drying the moisture in rice, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A device for drying rice includes a drying chamber with a circulation mechanism inside for circulating and heating the rice. The drying chamber has a top cover, a heat inlet on one side of the drying chamber, a feed inlet on one side of the top cover, a baffle inside the feed inlet that extends and retracts on the feed inlet side, a wind box on the other side of the top cover, a fan inside the wind box, and an exhaust port on the top of the wind box.
[0007] In a preferred embodiment of this utility model, a baffle mesh is provided inside the heat inlet, and a support column is provided on the outer side of the bottom of the drying box.
[0008] In a preferred embodiment of this utility model, an electric push rod is provided on the outer side of the feed inlet, and the electric push rod is connected to a baffle.
[0009] In a preferred embodiment of this utility model, a filter screen is provided at the bottom of the inner side of the air box, and a first electric valve is provided on one side of the exhaust port.
[0010] In a preferred embodiment of this utility model, the circulation mechanism includes a rotating component, a circulation pipe is provided below the rotating component, a motor is provided on the inner side of the top of the drying box, the motor is connected to the rotating component, a rotating ring is provided on the outer side of the rotating component, the rotating ring is attached to the inner wall of the drying box, and push blocks are provided on both sides of the bottom of the rotating ring.
[0011] In a preferred embodiment of this utility model, circulation inlets are provided on both sides of the bottom of the circulation pipe, and circulation outlets are provided on both sides of the top of the circulation pipe.
[0012] In a preferred embodiment of the present invention, a rotating shaft is provided inside the circulation tube, and a spiral blade is provided on the outside of the rotating shaft. The top of the rotating shaft is connected to the bottom of the inner side of the rotating component.
[0013] In a preferred embodiment of this utility model, a discharge port is provided on the inner side of the bottom of the drying box, and a second electric valve is provided on one side of the discharge port.
[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
[0015] Beneficial effects: This equipment uses a fan to blow air outwards, allowing the water vapor inside the drying chamber to be quickly discharged. When there is little water vapor inside, the exhaust port is closed by the first electric valve, ensuring that heat is not lost from the drying chamber. When the rice inside is drying, the motor drives the rotating parts to rotate, causing the rotating ring and shaft to rotate. This, in turn, pushes the rice inside, making the rice move around. The rice at the bottom enters the circulation pipe through the circulation inlet and is transported to the circulation outlet by the spiral blades. This ensures that the rice inside is heated evenly, and the increased heating of the rice, through mutual heat transfer, achieves a rapid drying effect.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0024] Please refer to Figures 1-4 This utility model discloses a device for drying the moisture of rice, including a drying chamber 1, which is the main structure of the device and is similar to current dryers. It dries rice by means of hot air. A heat inlet 12 is provided on one side of the drying chamber 1, through which hot air enters the drying chamber 1. A baffle 13 is provided inside the heat inlet 12 to block the grain inside. A support column 14 is provided on the outer side of the bottom of the drying chamber 1 to support the drying chamber 1. A top cover 11 is provided on the top of the drying chamber 1, which closes the top of the drying chamber 1. A discharge port 44 is provided on the inner side of the bottom of the drying chamber 1. A second electric valve 45 is provided on one side of the discharge port 44. After drying is completed, the discharge port 44 is opened by the second electric valve 45 to discharge the rice through the discharge port 44.
[0025] A feed inlet 2 is provided on one side of the top cover 11, through which rice is fed into the drying chamber 1. A baffle 22 is provided inside the feed inlet 2, which extends and retracts on one side of the feed inlet 2. An electric push rod 21 is provided on the outside of the feed inlet 2, which is connected to the baffle 22. The electric push rod 21 drives the baffle 22 to extend and retract, thereby opening and closing the feed inlet 2. A wind box 3 is provided on the other side of the top cover 11, with a fan 31 inside the wind box 3. An exhaust port 32 is provided at the top of the wind box 3, and a filter screen 33 is provided at the bottom inside the wind box 3. A first electric valve 34 is provided on one side of the exhaust port 32, through which the fan 31 blows air outward, thereby quickly expelling the water vapor inside the drying chamber. When there is little water vapor inside, the first electric valve 34 closes the exhaust port 32, thereby ensuring that the heat inside the drying chamber 1 is not lost.
[0026] The drying chamber 1 is equipped with a circulation mechanism for circulating and heating the rice. The circulation mechanism includes a rotating component 4, with a circulation pipe 5 located below the rotating component 4. A motor 41 is located on the inner top of the drying chamber 1, connected to the rotating component 4. A rotating ring 42 is located on the outer side of the rotating component 4, adhering to the inner wall of the drying chamber 1 and rotating. Pushing blocks 43 are located on both sides of the bottom of the rotating ring 42. Circulation inlets 51 are located on both sides of the bottom of the circulation pipe 5, and circulation outlets 52 are located on both sides of the top of the circulation pipe 5. A rotating shaft 53 is located inside the circulation pipe 5, with the outer side of the rotating shaft 53... Equipped with spiral blades 54, the top of the rotating shaft 53 is connected to the bottom of the inner side of the rotating component 4. When the rice inside is being dried, the rotating component 4 is driven to rotate by the motor 41, which in turn causes the rotating ring 42 and the rotating shaft 53 to rotate. This, in turn, pushes the rice inside by the push block 43, causing the rice to move inside. The rice at the bottom enters the circulation pipe 5 through the circulation inlet 51 and is then transported to the circulation outlet 52 by the spiral blades 54 for discharge. This ensures that the rice inside is heated evenly, and the increased heating of the rice, through mutual heat transfer, achieves a rapid drying effect.
[0027] The working principle of this utility model is as follows: When the equipment is in use, the hot air pipe is connected to the heat inlet 12, and hot air enters the drying chamber 1 through the heat inlet 12. Rice is fed into the chamber through the feed inlet 2. The electric push rod 21 drives the baffle 22 to extend and retract, thereby closing the feed inlet 2. The fan 31 blows air outwards, allowing the internal drying steam to be quickly discharged. When there is little internal steam, the first electric valve 34 closes the exhaust port 32, ensuring that heat is not lost from the drying chamber 1. During the drying of the rice inside, the... Motor 41 drives rotating component 4 to rotate, thereby causing rotating ring 42 and rotating shaft 53 to rotate. This pushes the rice inside by pushing block 43, causing the rice to move inside. The rice at the bottom enters the circulation pipe 5 through circulation inlet 51 and is transported to circulation outlet 52 by spiral blades 54 for discharge. This allows the rice inside to be heated evenly, and the increased heating of the rice, through mutual heat transfer, achieves a rapid drying effect. After drying, the discharge port 44 is opened by the second electric valve 45, allowing the rice to be discharged through the discharge port 44.
[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
