Description

Technical Field

[0001] The utility model relates to the technical field of rice production, in particular to a drying device for rice processing. Background Art

[0002] Rice production includes wheat ear harvesting, rice threshing, drying, screening and husking. Among them, the drying process mostly uses oven drying. Rice drying is an important link in the rice production process. It helps to remove moisture from rice and improve storage stability and quality.

[0003] Common rice drying methods include solar drying (the rice is spread on a flat ground or drying rack and exposed to the sun for drying. This method requires clear weather and sufficient sunlight resources), air drying (the rice is spread on a well-ventilated site, and the air is blown through the rice with the help of natural wind to take away the moisture. This method is suitable for areas with dry climate and good ventilation conditions), mechanical drying (the dryer usually uses a hot air circulation system to evaporate the moisture in the rice by heating the air and circulating it into the drying room. Mechanical drying can complete the drying process in a shorter time and has lower environmental requirements), oven drying (the rice is placed in an oven, and the temperature, humidity, ventilation and other parameters are controlled to gradually lose moisture. This method is suitable for smaller-scale production scenarios or situations where the drying process needs to be precisely controlled), etc.

[0004] In the existing rice drying device, such as the controlled amount filtering and drying device for rice processing disclosed in Patent Publication No. CN114017995B, rice grains will still accumulate during the drying process, resulting in different drying degrees of the rice in the upper and lower layers, leading to uneven drying. In order to solve the above-mentioned problem, a rice processing drying device is now provided. Utility Model Content

[0005] The utility model aims to provide a drying device for rice processing, so as to solve the problem that the rice grains of the existing rice drying device mentioned in the background art will still be piled up during the drying process, resulting in different drying degrees of the upper and lower layers of rice, resulting in uneven drying.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drying device for rice processing, comprising a frame of the drying device, a chamber for placing rice is opened at the upper end of the frame, a heating plate for drying grain is fixedly installed on the inner bottom surface of the chamber, a stirring mechanism for stirring rice is arranged in the chamber, the stirring mechanism comprises a sliding frame and stirring blades, two stirring blades are arranged, the stirring blades are rotatably installed in the interior of the sliding frame, and the two stirring blades are symmetrically arranged, the sliding frame is slidably installed in the chamber of the frame, the two stirring blades rotate to stir the rice placed in the chamber of the frame, the two stirring blades arranged oppositely make the rice collide and mix with each other during the stirring process, and then better stir the rice, so that the rice is contacted with the heating plate for drying, and the sliding frame slides so that the rice can be fully stirred.

[0007] As a preferred technical solution of the utility model, the heating plate is configured for electromagnetic heating, and the heating efficiency can be easily controlled by electromagnetic heating.

[0008] As a preferred technical solution of the utility model, a slide cylinder is fixedly connected to the upper end of the sliding frame, and a reciprocating screw rod for reciprocating the sliding frame is rotatably installed in the cavity of the frame. The slide cylinder is slidably sleeved on the outer wall of the reciprocating screw rod, and a slider for sliding in the threaded groove of the reciprocating screw rod is rotatably installed on the inner side of the slide cylinder. The rotation of the reciprocating screw rod drives the slide cylinder to slide back and forth on the outer wall of the reciprocating screw rod, thereby driving the sliding frame to slide back and forth in the cavity of the frame.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figure 1-5 This embodiment provides a drying device for rice processing, including a frame 1 of the drying device.

[0023] Specifically, Figure 1 As shown, the frame 1 is provided with a cavity, the opening of the cavity is upward, so that rice can be put into the cavity of the frame 1 conveniently.

[0024] like Figure 1 and Figure 2As shown, a cover 12 is rotatably mounted on the upper end of the frame 1. The cover 12 is made of transparent tempered glass, which facilitates sunlight to penetrate the cover 12 and irradiate into the chamber of the frame 1. There is a certain gap between the cover 12 and the frame 1, which facilitates the moisture of the rice to be discharged from the chamber of the frame 1.

[0025] like Figure 2 As shown, a heating plate 11 is fixedly installed at the bottom of the chamber of the frame 1. The heating plate 11 is configured for electromagnetic heating. The heating plate 11 heats the air in the chamber, thereby drying the rice placed in the chamber. The electromagnetically heated heating plate 11 is convenient for controlling the heating temperature, thereby facilitating the adjustment of the drying efficiency of the rice.

[0026] When the rice is dried in the frame 1 , the drying degrees of the upper and lower layers of the rice are different. Theoretically, the closer the rice is to the heating plate 11 , the faster it dries. In order to evenly dry the rice in the chamber of the frame 1 , a stirring mechanism 2 is provided in the chamber of the frame 1 .

[0027] Specifically, the stirring mechanism 2 includes a sliding frame 21 and a stirring blade 22 .

[0028] The sliding frame 21 is slidably mounted in the cavity of the frame 1. Figure 2 As shown, the upper end of the sliding frame 21 is fixedly connected to a slide cylinder 24, and a reciprocating screw 241 is rotatably installed in the chamber of the frame 1. A slider is rotatably installed inside the slide cylinder 24, and the reciprocating screw 241 is a reciprocating screw with a reference model of T30. The slide cylinder 24 is slidably sleeved on the outer side wall of the reciprocating screw 241, and the slider in the slide cylinder 24 is slidably installed in the thread groove of the reciprocating screw 241.

[0029] A first motor is fixedly installed inside the frame 1, and one end of the reciprocating screw 241 is fixedly connected to the output shaft of the first motor. When the first motor is started, the reciprocating screw 241 can be driven to rotate. The rotation of the reciprocating screw 241 can drive the slide 24 to slide back and forth on the outer wall of the reciprocating screw 241, that is, the sliding frame 21 moves back and forth in the chamber of the frame 1.

[0030] like Figure 5 As shown, the stirring blades 22 are provided in two, and the two stirring blades 22 are both rotatably mounted in the sliding frame 21, and the two stirring blades 22 are symmetrically arranged, as shown in FIG. Figure 4 As shown, a linkage mechanism 23 for synchronously rotating the stirring blade 22 is arranged in the side wall of the sliding frame 21 .

[0031] Specifically, the linkage mechanism 23 includes a control gear 231 and a linkage gear 232. Figure 5 As shown, the control gear 231 is fixedly connected to both ends of the stirring blade 22. Figure 4As shown, the control gear 231 and the linkage gear 232 are both rotatably mounted in the side wall of the sliding frame 21. Taking the side wall of the sliding frame 21 as an example, the control gears 231 at one end of the two stirring blades 22 are meshed with a linkage gear 232, and the two linkage gears 232 are meshed with each other. A second motor is fixedly installed in one side wall of the sliding frame 21, and a control gear 231 is fixedly connected to the output shaft of the second motor. When the second motor is started, it drives one control gear 231 to rotate, and the other control gear 231 can be driven to rotate through the two linkage gears 232, so that the two control gears 231 rotate synchronously. Figure 5 For example, the stirring blade 22 on the left side rotates counterclockwise, and the stirring blade 22 on the right side rotates clockwise.

[0032] The two stirring blades 22 rotate synchronously to shovel the rice in the chamber of the frame 1, so that the rice collides and mixes with each other. At the same time, the reciprocating movement of the sliding frame 21 further drives the stirring blades 22 to stir the rice comprehensively, so that the rice is evenly contacted with the heating plate 11 for even heating.

[0033] In order to stabilize the sliding of the sliding frame 21 , a rail 13 is fixedly connected in the chamber of the frame 1 . The sliding frame 21 is provided with a rail groove, which allows the sliding frame 21 to slide and snap onto the rail 13 . The rail 13 can stabilize the sliding of the sliding frame 21 .

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
