Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice drying technology, specifically a rice drying device for rice processing. Background Technology
[0002] Rice, also known as paddy rice, is the staple food of more than half of the world's population. It is made from paddy through cleaning, hulling, milling, and finishing processes. As a plant of the genus Oryza in the family Poaceae, rice is classified by grain shape into long grain, medium grain, and short grain; by variety into indica rice, japonica rice, and glutinous rice; and by processing depth into brown rice and polished rice.
[0003] The drying process is particularly crucial in rice processing, as it facilitates subsequent packaging and storage. However, traditional rice drying methods often involve conveyor belts transporting rice to a drying chamber. When rice is piled up, the heat flow within the drying chamber cannot effectively dry the rice inside, leading to high energy consumption and uneven drying. This not only affects the quality of the rice but also increases production costs. Therefore, a rice drying device for rice processing is proposed to address these issues. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology and solve at least one technical problem in the background technology, this utility model proposes a rice drying device for rice processing.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a rice drying device for rice processing, comprising a base frame, an adjustment mechanism and a drying cylinder, wherein the drying cylinder is installed on the base frame through the adjustment mechanism and is used for rice drying operation;
[0006] The motor is fixedly mounted on the surface of the drying drum, and the output shaft of the motor is rotatably connected through the side wall of the drying drum. The motor is a geared motor.
[0007] A drum is rotatably connected inside the drying cylinder, and the drum is driven by a motor;
[0008] The roller is driven by gear meshing with the output shaft of the motor;
[0009] A drying tube is fixedly connected inside the drying cylinder. Several air outlets are opened on the surface of the drying tube. An air inlet pipe is connected to the outside of the drying cylinder through the drying tube. The gas in the air inlet pipe is a hot air flow.
[0010] The surface of the drying cylinder is provided with a feed inlet and a discharge outlet.
[0011] Preferably, the surface of the drum is provided with mesh holes, and a slag outlet is provided on one side of the drying drum.

[0014] Preferably, at least three toggle blocks are provided, and they are evenly distributed.
[0015] Preferably, the adjusting mechanism includes a support, which is rotatably connected to the surface of the drying cylinder with a discharge port. A base plate is fixedly connected to the surface of the drying cylinder away from the support. A rotating frame is rotatably connected to the surface of the base plate. A threaded rod is rotatably connected to the surface of the base plate. The threaded rod passes through the rotating frame and is connected by threads.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Example 1
[0034] Please see Figure 1-7 As shown, a rice drying device for rice processing includes a base frame 1, an adjustment mechanism 5, and a drying cylinder 8. The drying cylinder 8 is installed on the base frame 1 through the adjustment mechanism 5 and is used for drying rice.
[0035] Motor 3 is fixedly installed on the surface of drying cylinder 8. The output shaft of motor 3 passes through the side wall of drying cylinder 8 and is rotatably connected. Motor 3 is a geared motor.
[0036] A drum 18 is rotatably connected inside the drying drum 8, and the drum 18 is driven by a motor 3.
[0037] The roller 18 is driven by gear meshing with the output shaft of the motor 3;
[0038] A drying tube 17 is fixedly connected inside the drying cylinder 8. Several air outlets are opened on the surface of the drying tube 17. The drying tube 17 passes through the side wall of the drying cylinder 8 and is connected to an air inlet pipe 6. The gas in the air inlet pipe 6 is a hot air flow.
[0039] The surface of the drying cylinder 8 is provided with a feed inlet 7 and a discharge outlet 16;
[0040] The adjusting mechanism 5 includes a bracket 11, which is rotatably connected to the surface of the drying cylinder 8 with the discharge port 16. A base plate 22 is fixedly connected to the surface of the drying cylinder 8 away from the bracket 11. A rotating frame 23 is rotatably connected to the surface of the base plate 22. A threaded rod 27 is rotatably connected to the surface of the base plate 1. The threaded rod 27 passes through the rotating frame 23 and is connected by threads. A fixing plate 25 is fixedly connected to the surface of the rotating frame 23. A insertion shaft 26 is slidably connected to the surface of the fixing plate 25 by a spring. Several insertion holes are opened on the surface of the threaded rod 27 relative to the insertion shaft 26.
[0041] During operation, motor 3 is first turned on, and the drying airflow is simultaneously delivered to the drying drum 8 through the air inlet pipe 6. Then, the rice to be dried is introduced into the drum 18 through the feed inlet 7. At this time, the drum 18, driven by motor 3, will repeatedly stir the rice, while air is blown onto the rice through the air outlet on the surface of the drying pipe 17, thereby achieving the drying effect. The drum 18 can stir and repeatedly turn the rice, thus preventing it from piling up. The heat flow inside the drying chamber cannot dry the rice inside, thus avoiding problems such as high drying energy consumption and uneven drying. Finally, the dried rice is discharged through the discharge outlet 16. By adjusting mechanism 5, when the internal moisture content of the rice is high, it is necessary to extend the residence time of the rice in the drying drum 8. At this time, the insertion shaft 26 can be slid away from the threaded rod 27 to release the restriction on the axial rotation of the threaded rod 27. Then the threaded rod 27 can be rotated, which drives the rotating frame 23 to rise and fall, thereby increasing or decreasing the angle of the drying drum 8. This is reflected in the drum 18 by making the drum 18 flat or steep, thereby adjusting the residence time of the rice in the drying drum 8, and thus achieving the purpose of drying rice with different moisture contents.
[0042] The surface of the drum 18 is provided with mesh holes, and the side of the drying drum 8 is provided with a slag outlet 15. During operation, the broken parts and fine sand in the rice can be filtered through the mesh holes on the surface of the drum 18 and finally discharged through the slag outlet 15, thereby improving the quality of the rice.
[0043] A guide plate 9 is provided on one side of the discharge port 16. The guide plate 9 is arc-shaped. During operation, the arc-shaped guide plate 9 will gather the rice in the middle, which makes it easier to receive the rice, or guide the rice to the conveyor belt for the next process.
[0044] A sliding rod 12 is slidably connected to the side wall of the drying drum 8 via a spring. An impact head 19 is fixedly connected to the surface of the sliding rod 12. A rubber pad is fixedly connected to the surface of the impact head 19. A lever 13 is fixedly connected to the surface of the drum 18. The surface of the lever 13 is provided with an angle. There are at least three levers 13, which are evenly distributed.
[0045] During operation, as the drum 18 rotates, it drives the paddle blocks 13 on its surface to move. When the paddle blocks 13 move to the position of the slide bar 12, the angled surface of the paddle blocks 13 will press the paddle bar upward, and at the same time drive the impact head 19 away from the drum 18. After the paddle blocks 13 pass the slide bar 12, the spring drives the slide bar 12, and the slide bar 12 drives the impact head 19 to reset, so that the impact head 19 impacts the drum 18. The resulting vibration can clean the rice in the mesh holes on the surface of the drum 18, so as to avoid affecting the screening efficiency of the drum 18. The design of multiple paddle blocks 13 can increase the impact frequency, thereby improving the cleaning effect.
[0046] Example 2
[0047] Please see Figure 8 As shown in the first embodiment, as another implementation of this utility model, a number of sieve plates 28 are fixedly connected to the inner wall of the drum 18, and a number of protrusions are fixedly connected to the surface of the sieve plates 28. When working, the drum 18 rotates, which drives the internal sieve plates 28 to rotate. The rice can be divided into several portions through the sieve plates 28. At the same time, due to gravity during rotation, and in conjunction with the protrusions on the surface of the sieve plates 28, the rice will be dispersed again, thereby further improving the drying efficiency.
