The water content of rice is very high after harvest. In order to ensure the safe storage of rice, the moisture content of rice must be reduced to a safe moisture content for storage. The drying of rice is different from that of other grains. Rice is a heat-sensitive crop. If the drying speed is too fast or the parameters are not properly selected, it is easy to cause rice to burst. The dryer is a commonly used rice drying equipment. By putting rice into the dryer, it goes through the steps of preheating, drying, slow thawing, cooling, etc., and finally obtains the dried rice, which can then be stored.

The semi-ring connector 4 is installed at the position of the air hole 3, the inner side of the semi-ring connector 4 is communicated with the air hole 3, the opening of the semi-ring connector 4 is downward, and the air-permeable net 5 is installed at the opening position of the semi-ring connector 4, which is convenient for drying. Dry and breathable, one end of the semi-ring connector 4 is installed with an inner cylinder 6 corresponding to the inner position of the outer cylinder 2, a drying chamber 7 is formed between the outer cylinder 2 and the inner cylinder 6, a rice inlet 8 is installed on the top of the outer cylinder 2, and the rice inlet 8 is an open trumpet-shaped structure. The bottoms of the outer cylinder 2 and the inner cylinder 6 are both placed on the top surface of the equipment bracket 1 to facilitate the input and output of rice. A top air cylinder 9 is installed on the top of the inner cylinder 6, an exhaust fan 10 is installed inside the top air cylinder 9, a support rod 11 is installed on the top of the top air cylinder 9, and a dustproof plate 12 is installed on the top of the support rod 11;

[0026] A vibration motor 13 is installed in the middle of the inner side of the inner cylinder 6. Two vibration motors 13 are symmetrically installed on the inner side of the inner cylinder 6 to facilitate the movement of rice in the drying chamber 7. Protective cylinders 14 are installed on the top and bottom of the inner side of the inner cylinder 6. A resistance heating wire 15 is installed between the protective cylinder 14 and the inner cylinder 6. The input ends of the vibration motor 13, the exhaust fan 10 and the resistance heating wire 15 are all electrically connected to the output end of the external power supply. A rice outlet frame 23 is installed at the bottom of the outer cylinder 2 and the inner cylinder 6. A sealing baffle 24 is slidably engaged in the middle of the rice outlet frame 23.

[0027] A fixed frame 16 is installed in the middle position of the outside of the inner cylinder 6, and a movable frame 17 is slidably connected to the inside of the outer cylinder 2. A connecting block 18 is symmetrically installed on the outside of the movable frame 17. A movable hole 19 is symmetrically opened on the outside of the outer cylinder 2. A fitting plate 20 is installed at the bottom of the connecting block 18. The fitting plate 20 slides and fits with the movable hole 19 on the outside of the outer cylinder 2. The connecting block 18 is connected to the inside of the movable hole 19 to facilitate the installation of the movable frame 17. A fixing seat 21 is symmetrically installed on the outside of the outer cylinder 2. An electric push rod 22 is installed on the top of the fixing seat 21.

The input end of the electric push rod 22 is electrically connected to the output end of the external power supply, which is convenient for driving the movable frame 17 to move.

[0028] The working principle and use process of the utility model are as follows: when drying rice, the power supply of the resistance heating wire 15 is turned on to start preheating, and the electric push rod 22 pushes the connecting block 18 and the movable frame 17 upward, so that the movable frame 17 contacts the fixed frame 16, and the drying chamber 7 is divided in the middle position;

[0029] The rice is then poured into the top of the drying chamber 7 from the rice inlet 8 and heated by the resistance heating wire 15 on the top, thereby drying the rice inside the drying chamber 7.

Since the contact area between the rice and the inner cylinder 6 and the outer cylinder 2 is large, the drying is more uniform.

[0030] After the rice at the top has been dried for a period of time, the electric push rod 22 drives the connecting block 18 and the movable frame 17 to move downward, separating the movable frame 17 from the fixed frame 16. The vibration motor 13 is powered on to vibrate the inner drum 6, thereby moving the rice at the top toward the bottom. During the movement, the position of the rice changes, thereby enabling the rice to be redistributed and evenly heated. The resistance heating wire 15 at the bottom continues to heat the rice. When the rice at the bottom is heated, the electric push rod 22 can be used to drive the connecting block 18 and the movable frame 17 to move upward to contact the fixed frame 16, and the rice can be poured into the rice inlet 8 again to achieve continuous and uninterrupted drying.

[0031] After drying, the sealing baffle 24 is pulled out from the rice outlet frame 23, and the rice is discharged from the rice outlet frame 23. After the drying equipment is used, the exhaust fan 10 is used to accelerate heat dissipation, so that the rice can be cooled quickly for subsequent use.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
