AI Technical Summary
In existing rice drying devices, the stirring mechanism cannot stir the rice sufficiently, resulting in rice near the drying fan being easily dried, while rice further away cannot fully contact the drying air, leading to uneven drying.
The drying chamber is divided into four compartments by a barrier net inside the rotating drum. Each compartment is equipped with a stirring mechanism. The rotation of the rotating drum drives the barrier net and the stirring component to ensure that the rice in each compartment is evenly exposed to the drying air. The stirring component also agitates the rice, thereby enhancing the drying efficiency.
This method achieves uniform drying of rice, improves drying efficiency, ensures that rice in each chamber is fully exposed to the drying air, and enhances the drying effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, and in particular to a rice processing and drying device. Background Technology
[0002] Rice, also known as paddy rice, is a food made from paddy rice through processes such as cleaning, hulling, milling, and finishing. Rice is a staple food for people in most parts of China.
[0003] The drying process in rice processing is crucial for ensuring the quality of the finished product. Scientific control of temperature and humidity is used to reduce the moisture content of the paddy rice. Traditional sun-drying methods are inefficient and subject to weather conditions. Modern drying technology uses a hot air circulation system to achieve uniform drying while preventing damage to the rice grains. Intelligent drying equipment can automatically adjust temperature and airflow, and some are even equipped with waste heat recovery functions, which improves efficiency, saves energy, and ensures that the rice maintains stable quality during storage and transportation.
[0004] Patent document CN209333796U discloses a rice drying device, which includes a drying chamber, with a feeding hopper and a discharge pipe respectively provided at the upper and side ends of the drying chamber; a screen is provided in the middle of the drying chamber, dividing the drying chamber into an upper drying chamber and a lower drying chamber; a rotating shaft is provided in the middle of the drying chamber, passing through the screen, and connected to a drive mechanism; a spiral stirring device is provided on the rotating shaft, and multiple bushings are movably arranged on the rotating shaft, with dust removal devices provided on the bushings. The dust removal device includes a support frame, with multiple cylinders arranged on the support frame, and springs are installed inside the cylinders. The springs are connected to brush balls through connecting plates; heating devices are provided on both sides of the drying chamber (2). This utility model provides a rice drying device with a simple structure and convenient use. It can not only dry rice but also remove dust, with high efficiency and strong practicality.
[0005] As in the prior art of the aforementioned patent, the amount of rice to be dried is generally large, and traditional drying chambers are generally large. In order to ensure that the rice can be fully dried, a stirring mechanism is needed to continuously stir the rice. However, a typical stirring mechanism cannot fully stir the rice. For example, the rice in the upper layer can only be stirred on the same horizontal plane and cannot fully come into contact with the drying air coming in from below. This results in the rice closer to the drying fan being easier to dry, while the rice further away cannot be fully stirred and moved to the drying fan, so it is more difficult to dry.

In addition, the stirring mechanism inside each chamber also agitates the rice in its respective chamber, increasing the drying efficiency.
[0027] As a preferred technical solution of this embodiment, the stirring mechanism includes four rotating shafts 15, which are rotatably connected to the rotating cylinder 4. The four rotating shafts 15 are respectively arranged between multiple barrier nets 14, and stirring components 16 are fixedly installed on the four rotating shafts 15.

A cover plate 5 is fixedly mounted on the drying chamber 3, and an end face gear ring 18 is fixedly mounted on the inner wall of the cover plate 5. The end face gear ring 18 meshes with the multiple gears 17. When the rotating cylinder 4 rotates, it drives the multiple rotating shafts 15 to rotate. The gear 17 at one end of the rotating shaft 15 can rotate under the action of the end face gear ring 18, further realizing the rotation and stirring of the stirring component 16.
[0029] As a preferred technical solution of this embodiment, a motor 2 is fixedly installed inside the housing 1. The output end of the motor 2 is connected to the rotating cylinder 4 for transmission. A sealing element 20 is provided at the connection between the rotating cylinder 4 and the drying chamber 3.
