Description

Technical Field

[0001] This utility model relates to the field of rice drying technology, specifically a rice dryer for rice processing. Background Technology

[0002] Rice is a finished product made from paddy rice through processes such as cleaning, hulling, milling, and finishing.

[0003] A search revealed a utility model patent in China with patent publication number CN218993906U, which discloses a rice drying device for rice processing. The device generally includes a tank with a base fixedly connected to its bottom. A water filtration mechanism is located at the bottom of the tank. This mechanism includes a water inlet plate fixedly connected to the inner wall of the tank's bottom. During operation, by activating the cylinder and a telescopic rod, the water filtration mechanism causes the filter plate to vibrate, breaking up clumps of rice. Simultaneously, water passes through the filter plate and falls onto the water inlet plate, exiting through a drain pipe. This provides preliminary water filtration for the washed rice, accelerating the overall drying time. A stirring device continuously agitates the rice inside the tank during the drying process, ensuring even heating. However, this device has certain shortcomings. For example, it lacks a sieving function, making it impossible to separate rice particles of different sizes, thus reducing rice quality, inconvenience for users, and diminishing the dryer's practicality. Therefore, we propose a rice dryer for rice processing. Utility Model Content

[0025] Example

[0026] Please see Figure 1-Figure 4 A rice dryer for rice processing, comprising:

[0027] Box 1, with a feed hopper connected to it;

[0028] The screening mechanism is mounted on the housing 1 and includes a guide plate 2, a feeding cylinder 3, a collecting mesh trough 4, and four fixed blocks 5. The guide plate 2 is fixedly connected inside the housing 1. The feeding cylinder 3 is mounted on the housing 1 and connected to the housing 1 through an opening. The collecting mesh trough 4 is installed through the housing 1. All four fixed blocks 5 are fixedly connected to the housing 1. A telescopic rod 6 is fixedly connected to each fixed block 5. A second fixed block 7 is fixedly connected to each telescopic rod 6. A spring is fitted onto each telescopic rod 6. Fixed grooves 8 are fixedly connected to each of the four fixed blocks 7. A screen 9 is provided, and a vibrating motor 10 is installed on the fixed groove 8. The feeding cylinder 3 is connected to the feeding hopper through the discharge pipe 11. A spiral feeding shaft 12 is rotatably connected inside the feeding cylinder 3. A motor 13 is installed on the feeding cylinder 3. The output end of the motor 13 enters the feeding cylinder 3 and is fixedly connected to the spiral feeding shaft 12. The screen 9 is used to screen the rice, the vibrating motor 10 is used for vibration, and springs, telescopic rods 6, etc. are used to improve the vibration effect of screening. The spiral feeding shaft 12, the feeding cylinder 3, etc. are used to transport the rice at the bottom of the box 1 to the top of the box 1 to achieve circulation.

[0029] The drying mechanism includes a water filter 14, a mounting plate, a blower box 15, and a connecting block. The water filter 14 is mounted on the guide plate 2. The mounting plate is fixedly connected to the housing 1. The blower box 15 and the connecting block are both fixedly connected inside the housing 1. A blower box 2 16 is fixedly connected to the connecting block. Both the blower box 15 and the blower box 2 16 have multiple air outlets. A hot air blower 17 is mounted on the mounting plate. The air outlet of the hot air blower 17 is connected to a pipe 18. The pipe 18 passes through the housing 1 and enters the blower box 15. A pipe 2 19 is connected to the pipe 18. The pipe 2 19 passes through the housing 1 and enters the blower box 2 16. The hot air blower 17 is used to blow hot air. The blower box 15 and the blower box 2 16 are used for large-area air blowing to facilitate better drying of rice.

[0030] A shielding door 20 is rotatably connected to the feeding cylinder 3. A latch lock is installed between the shielding door 20 and the feeding cylinder 3 to facilitate people to take out the dried rice.

[0031] Two support plates 21 are fixedly connected inside the housing 1. The collection net trough 4 is located on the two support plates 21. A handle is fixedly connected to the collection net trough 4 to support it and improve its stability.

[0032] The box 1 has an exhaust vent, and an exhaust fan 22 is installed in the exhaust vent to remove the moisture generated during the drying of rice.

[0033] A water outlet pipe 23 is connected to the tank 1, and a valve is installed on the water outlet pipe 23 to discharge excess water.

[0034] It should be further explained that the hot air blower 17, exhaust fan 22, motor 13 and vibration motor 10 in this embodiment are conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. The hot air blower 17, exhaust fan 22, motor 13 and vibration motor 10 are equipped with matching control switches. The installation position of the control switches can be selected according to actual usage needs to facilitate operation and control by the operator.

[0035] In summary, the working principle and process of this rice dryer for rice processing are as follows: First, place the rice dryer at the desired location. Then, start the hot air blower 17, vibrating motor 10, motor 13, and exhaust fan 22. Next, add rice into the feed chamber 1 through the feed hopper. The rice will fall into the fixed inlet trough 8. Water from the rice will drip into the chamber 1 through the screen 9, collection trough 4, and filter screen 14. The water can be released by opening the valve. Water is discharged through pipe 23. The vibrating motor 10, spring, and telescopic rod 6 work together to vibrate the fixed trough 8. The rice in the fixed trough 8 is screened by the sieve 9, and smaller rice grains fall into the collection trough 4. Because the fixed trough 8 is inclined, the rice continues to fall onto the guide plate 2. At the same time, the activated hot air blower 17 blows out hot air, which is transported by pipes 18 and 29 to blower boxes 15 and 26, and then passes through blower boxes 15 and 26. The hot air is discharged from the air outlet on the top. The air blower 15 blows hot air into the fixed groove 8, where the dispersed rice is dried. The air blower 26 dries the falling rice and the rice on the guide plate 2 evenly. The exhaust fan 22 then discharges the moisture generated during drying. The rice is then guided by the guide plate 2 into the feeding cylinder 3. The motor 13 drives the screw feeding shaft 12 to rotate, feeding the rice back into the feed hopper. This achieves the effect of circulating screening and drying of rice, improving practicality. When it is necessary to remove the rice, people open the latch lock, turn the shield door 20, and then slowly drive the screw feeding shaft 12 to rotate. This prevents the rice from being carried to a high place by the screw feeding shaft 12, thus allowing the dried rice to be discharged. The rotating screw feeding shaft 12 also prevents rice from clogging the discharge. Smaller rice pieces can be removed directly by taking out the collection mesh trough 4 by hand. This device improves the quality of rice and enhances practicality.

[0036] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
