[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] according to Figure 1-6 This utility model provides a low-temperature drying device for rice processing, including: a drying cabinet 1 and a hot air blower 2.

[0024] The drying cabinet 1 includes: a shell 11, a rack 12, and an air outlet 13; there are several racks 12; the racks 12 are arranged from top to bottom inside the shell 11; a hot air blower 2 extends into the shell 11; the hot air blower 2 is located at the bottom of the rack 12; the air outlet 13 is located on the side of the rack 12 away from the hot air blower 2; the rack 12 includes: a screen 121; the screen 121 is located on the side of the rack 12 close to the hot air blower 2.

[0025] When drying rice is required, the cabinet door can be opened, the rice placed on several racks 12, the cabinet door closed, and the hot air blower 2 turned on, allowing hot air of a certain temperature to enter the bottom of the drying cabinet 1. By directing the hot air outlet towards the racks 12, the hot air flows towards the racks 12 after entering. The bottom of the racks 12 is a screen 121, ensuring that the rice inside the racks 12 is in contact with the hot air and is thus dried. When drying rice, if the temperature is too high, such as above 60°C, it can easily damage the proteins, enzymes, and other substances in the rice. Conversely, if the temperature is too low, such as 35°C-45°C, the drying efficiency will be relatively low. This invention allows the hot air blower 2 to blow out lower-temperature hot air, and by setting multiple racks 12, the rice can be distributed in different layers, increasing the overall contact area of ​​the rice and thus improving the drying efficiency. It also prevents the rice from being piled up in large quantities, which would make the rice inside difficult to dry. The hot air passing through each rack 12 continues to rise and contact the rice on the rack above it, and so on, ensuring that the rice on multiple racks 12 is dried. Finally, the hot air carries away the moisture from the rice and exits through the air outlet 13 to prevent excessive humidity inside the drying cabinet 1. In short, the drying cabinet 1 and the hot air blower 2 enable the rice to be dried even in poor weather conditions, preventing disruption to rice production or mold growth due to prolonged waiting.

[0026] The screen 121 includes: horizontal bars 1211 and vertical bars 1212; there are several horizontal bars 1211 and several vertical bars 1212; the horizontal bars 1211 and vertical bars 1212 are perpendicular to each other. The drying cabinet 1 also includes: a support plate 14; the support plate 14 includes: a support groove 141 and support rods 142; several support rods 142 are arranged in the support groove 141; the support rods 142 are parallel to the horizontal bars 1211; the support rods 142 are movable relative to the horizontal bars 1211. The distance between adjacent horizontal bars 1211 is greater than the distance between adjacent vertical bars 1212; the distance between adjacent support rods 142 is the same as the distance between adjacent horizontal bars 1211. The inner wall of the housing 11 has a sliding groove 111; the two sides of the support plate 14 can slide into the sliding groove 111; the support plate 14 also includes: a connecting rod 143 and a screw 144; the connecting rod 143 is rotatably connected to the screw 144; the housing 11 has a screw groove that matches the screw 144; the screw 144 passes through the screw groove.

[0027] The screen 121 consists of horizontal bars 1211 and vertical bars 1212, as well as a support rod 142. By setting the distance between adjacent vertical bars 1212 to be smaller than the size of the rice grains, the rice grains are prevented from falling. Simultaneously, the distance between adjacent horizontal bars 1211 is larger than the size of the rice grains. The support rod 142 is positioned between adjacent horizontal bars 1211, with the distance between the support rod 142 and the nearest horizontal bar 1211 being smaller than the size of the rice grains, making it difficult for the rice grains to fall. In other words, through the combined constraint of the horizontal bars 1211, vertical bars 1212, and support rod 142, the rice grains are stably placed within the rack 12. The support rod 142 is movable relative to the horizontal bars 1211, meaning its position can be adjusted so that the rice grains between the horizontal bars 1211 are no longer obstructed by the support rod 142 and can fall naturally. This allows the rice grains to tumble during the fall, ensuring they are turned during hot air drying and preventing uneven heating that could affect the drying process. When the support rod 142 needs to be moved, the screw 144 can be rotated, so that the screw 144 is screwed in or out along the screw groove. The connecting rod 143 is connected to the screw 144, so that the connecting rod 143 will not rotate with the screw 144, but will move with the screw 144. At the same time, the connecting rod 143 drives the support plate 14 to slide along the slide groove 111, so that the support rod 142 moves to below the crossbar 1211, so that the support rod 142 and the crossbar 1211 are on the same vertical line, at which point the rice can fall.

[0028] The drying cabinet 1 also includes: a straight rod 15; the placement rack 12 includes: a connecting column 122 and a sliding block 123; the connecting column 122 extends and retracts through the housing 11; the straight rod 15 is located on the outside of the housing 11; the connecting column 122 is connected to the straight rod 15; a limiting groove 112 is opened on the inner wall of the housing 11; the sliding block 123 is slidably disposed in the limiting groove 112. The drying cabinet 1 also includes: a motor 16 and a drive rod 17; the motor 16 includes: a turntable 161 and an eccentric column 162; the eccentric column 162 is located on one side of the center of the turntable 161; the straight rod 15 includes: a drive column 151; one side of the drive rod 17 is rotatably sleeved on the eccentric column 162, and the other side is rotatably sleeved on the drive column 151. The drying cabinet 1 also includes: a storage rack 18; the storage rack 18 is located on the side of the placement rack 12 near the hot air blower 2; the bottom side of the storage rack 18 has filter holes. The inner wall of the housing 11 is provided with a support block so that the storage rack 18 can be placed on the support block.

[0029] However, simply moving the support rod 142 will cause some rice grains to remain inside the placement rack 12. This invention can activate the motor 16, causing the turntable 161 to rotate, which in turn drives the eccentric column 162 to rotate. The eccentric column 162, in turn, causes the driving rod 17 to move. The two ends of the driving rod 17 are rotatably fitted onto the eccentric column 162 and the driving column 151, respectively. The driving column 151 is mounted on a straight rod 15, which is connected to the connecting column 122 of the placement rack 12. The sliding block 123 of the placement rack 12 is located within the limiting groove 112, ensuring that the placement rack 12 can only move along the limiting groove 112. This also ensures that the driving column 151 can only move in a direction parallel to the limiting groove 112. Therefore, when the driving rod 17 is driven by the eccentric column 162, both ends will rotate around the eccentric column 162 and the driving column 151, respectively, causing the driving rod 17 to move... The eccentric column 162 rotates back and forth, causing the drive rod 17 to drive the drive column 151 to move away from the turntable 161 when the eccentric column 162 rotates to the position closest to the housing 11. When the eccentric column 162 rotates to the position furthest from the housing 11, the drive rod 17 drives the drive column 151 to move closer to the turntable 161. That is, as the eccentric column 162 rotates cyclically, the drive column 151 is driven back and forth, causing the placement rack 12 to move back and forth. This causes the rice on the placement rack 12 to be shaken off, making it difficult for the rice to remain in the placement rack 12. The back and forth movement of the placement rack 12 also makes the rice in the placement rack 12 more evenly distributed, avoiding accumulation. The straight rod 15 connects several placement racks 12 together, so that they can move together, making them more convenient to use. The rice grains falling from the placement rack 12 will land in the storage rack 18. The storage rack 18 has filter holes on its bottom side to allow hot air to pass through and dry the rice evenly. Because the rice grains in the placement rack 12 fall through the gaps between multiple adjacent horizontal bars 1211, the rice falls relatively evenly, preventing it from piling up in the storage rack 18. After drying, the cabinet door can be opened to remove the rice grains from the storage rack 18.

[0030] In summary, this utility model dries rice by placing it on a rack inside a drying cabinet and using a hot air blower. This process can be carried out indoors even in inclement weather to prevent the rice from becoming moldy due to waiting for better weather for an extended period.
