Description

Technical Field

[0001] This utility model relates to the technical field of screening and drying devices, and more particularly to a screening and drying device. Background Technology

[0002] Rice is an important food crop, belonging to the Poaceae family. It typically grows in paddy fields and requires ample water for cultivation. The main food consumed is the rice seed, commonly known as rice grains. After processing, rice can be made into cooked rice, porridge, and other foods, and is a staple in the daily diet of people in many countries and regions.

[0003] Rice screening and drying refers to a series of meticulous screening and drying processes performed on harvested rice. The aim is to effectively remove various impurities mixed in with the rice and precisely adjust its moisture content, thereby ensuring the overall quality and safety of the rice during storage. Specifically, this process begins with a thorough screening of the rice. Using specialized screening equipment or manual methods, impurities such as weeds, mud, and rice husks are completely removed to ensure the purity of the rice. Subsequently, to further guarantee the quality of the rice, the screened rice undergoes a drying process. This step can be achieved through natural sun-drying, utilizing sunlight and wind to gradually reduce the moisture content, or by using modern drying machinery to quickly and evenly reduce the moisture content of the rice by controlling temperature and humidity, bringing it to a suitable storage standard. This series of screening and drying processes not only effectively prevents mold growth during storage but also significantly extends the storage time of the rice, ensuring its excellent quality during subsequent processing and use.

[0004] Existing devices cannot simultaneously dry and screen rice, and face problems such as incomplete drying and impurity removal during the drying and screening process. To overcome these disadvantages, this invention provides a screening and drying device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a screening and drying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a screening and drying device, comprising a box body, a feeding component provided at the top inlet of the box body, a cleaning component provided on the box body, a heating and drying component provided at the bottom of the box body, and a collection port provided at the front end of the box body, wherein a collection component is provided on the collection port.

[0007] Furthermore, the feeding assembly includes a funnel fixedly connected to the feeding port at the top of the box, a motor support frame fixedly connected to the top of the box and located on both sides of the funnel, a geared motor fixedly connected to the top of the motor support frame, a stirring component rotatably connected to the bottom of the motor support frame, and the output end of the geared motor fixedly connected to one end of the stirring component through the motor support frame.

[0008] Furthermore, the impurity removal component includes a first fan opening on the left side of the housing, a impurity removal fan fixedly connected to the first fan opening, several ventilation holes on the right side of the housing, an impurity removal chamber fixedly connected inside the housing and below the ventilation holes, a first collection box provided on the impurity removal chamber, and a first handle fixedly connected to one side of the first collection box.

[0009] Furthermore, the heating and drying assembly includes a heater fixedly connected to the bottom of the outer side of the chamber. The output end of the heater passes through the chamber and is fixedly connected to a spiral heating copper tube inside the chamber. A second fan opening is provided at the bottom of the outer side of the chamber and around the heater. A heating fan is fixedly connected to the second fan opening.

[0010] Furthermore, the collection assembly includes a second collection box disposed on the collection port, with slide rails fixedly connected to both the left and right sides of the collection port, and slide rods fixedly connected to both the left and right sides of the second collection box. The slide rods and slide rails are slidably connected. Several heating holes are provided at the bottom of the second collection box, and a second handle is fixedly connected to one side of the second collection box.

[0011] Furthermore, support frames are fixedly connected to the four corners of the bottom of the outer side of the box.

[0012] The beneficial effects of this utility model are:

[0013] In use, this screening and drying device uses a stirring component in the feeding assembly to stir the rice in the funnel that has not yet entered the box, preventing blockage at the feeding inlet and thus preventing the rice from entering the box. It also prevents the rice from concentrating in the box, which would result in poor impurity removal and drying effects. The impurity removal component blows empty rice husks and other impurities mixed in with the rice into the first collection box. The heater in the heating assembly heats the spiral heating copper tube. Then, the air blown out by the heating fan passes through the spiral heating copper tube and is heated. Finally, it passes through the heating hole in the second collection box, carrying away the moisture in the second collection box. Attached Figure Description

[0027] Working principle: When using the device, first check if the entire device is intact. After the check is completed, insert the first collection box 11 into the impurity removal chamber 10 and the second collection box 15 into the collection port 14. Then, start the impurity removal fan 3 and the heating fan 21. Then, start the heater 19 to heat the spiral heating copper tube 22. Then, add the rice to be screened and dried into the funnel 5. Then, start the reduction motor 7 to make the rice enter the box 1 in an orderly and small amount. The rice entering the box 1 is first blown by the impurity removal fan 3 into the impurity removal chamber 10, and then enters the first collection box 11 for collection. After the impurity removal is completed, the rice falls into the second collection box 15. Then, the air blown by the heating fan 21 is heated by the spiral heating copper tube 22. After heating, the hot air enters the second collection box 15 through the heating hole 17 at the bottom of the second collection box 15, taking away the moisture of the rice in the second collection box 15 and drying it.
