[0002] Fresh onions contain a high amount of water and are easily infected by microorganisms and spoil. Dehydration can reduce the moisture content of onions, thereby inhibiting the growth and reproduction of microorganisms and extending the shelf life of onions. This is very important for regulating market supply and demand, reducing losses, and long-distance transportation. The main method of dehydration is to dry the onion raw materials with hot air.

[0003] Most existing onion dehydration devices use a rotating drying drum structure for dehydration, but do not have a convenient discharging structure, or use a heavy mechanical structure to control the tilting of the drying drum as a whole for discharging. However, this discharging method takes a long time to operate, increases the number of motors used, is not conducive to equipment maintenance and repair, and is difficult to meet actual usage needs. Utility Model Content

The following describes the embodiments of the present invention based on its overall structure.

[0024] Reference Figures 1 to 3 In the embodiment of the utility model, an efficient onion dehydration device includes: a drying cylinder 1, one end of the drying cylinder 1 is fixedly connected to a rotating motor 2, the output end of the rotating motor 2 is provided with a rotating shaft 3, the end of the rotating shaft 3 is penetrated by a connecting hole 4, a screen cylinder 5 is mounted inside the drying cylinder 1, one end of the screen cylinder 5 is fixedly connected to a fixing component 6, a limiting column 7 is penetrated inside the fixing component 6, and a bearing ring 8 is fixedly sleeved on the other end of the screen cylinder 5. A screw hole seat 9 is fixedly embedded at one end of the bottom side of the drying cylinder 1, and an adjusting stud 10 is penetrated inside the screw hole seat 9.

[0025] Reference Figures 1 to 3 The limiting column 7 is limited and passes through the interior of the fixed component 6 and the connecting hole 4 at the end of the rotating shaft 3, so that the rotating shaft 3 and the screen cylinder 5 are rotatably connected to each other. The bearing ring 8 is fixedly sleeved on the outside of the open end of the screen cylinder 5. The arc-shaped side surface of the drying cylinder 1 corresponding to the bearing ring 8 is embedded with a screw hole seat 9 that is screwed into the adjusting stud 10, and there are two groups of screw hole seats 9 and adjusting studs 10, which are located at the open end of the drying cylinder 1 and are symmetrically arranged perpendicular to the barrel body of the screen cylinder 5.

[0026] Adopting the above scheme: when the screen drum 5 rotates, the adjusting studs 10 at the upper and lower ends are completely screwed into the screw hole seats 9 so that the two can stably press against the bearing ring 8 sleeved on one end of the outer side of the screen drum 5 to keep the screen drum 5 level. The supporting structure of the bearing ring 8 and the adjusting studs 10 can avoid affecting the stable rotation of the screen drum 5. At the same time, when discharging is required, the adjusting stud 10 at the bottom end is screwed out to tilt the screen drum 5 toward the discharging end, and the dehydrated onion raw materials can be discharged by tapping the drum body. The structure is simple and convenient, the number of motors used is reduced, and maintenance is easy.

[0027] Reference Figure 4 and Figure 5 The bottom end of the drying cylinder 1 is connected with a drying fan 11, and one end of the inner side of the drying cylinder 1 is fixedly connected with a slot part 12. A curved partition 13 is clamped inside the slot part 12, and a material-receiving dense mesh 14 is embedded in the curved partition 13. A limiting slot 15 is provided at one end of the curved partition 13. The air outlet direction of the drying fan 11 is perpendicular to the barrel body of the screen cylinder 5. There are two groups of slot parts 12, which are symmetrically arranged on the inside of the drying cylinder 1. The curved partition 13 is located between the two groups of slot parts 12 and is close to the inner bottom surface of the drying cylinder 1. The material-receiving dense mesh 14 is located in the curved partition 13 corresponding to the through-connection of the drying fan 11. The limiting slot 15 is an open slot and is adapted to the specifications of the screw hole seat 9.

[0028] The above scheme is adopted: the drying fan 11 is started to dry and dehydrate the material in the screen drum 5 with hot air. At the same time, the screen drum 5 rotates synchronously and uniformly under the action of the rotating motor 2 driving the rotating shaft 3 to rotate, and the drying fan 11 blows the raw materials upward from bottom to top, thereby improving the drying efficiency and speeding up the production speed.

[0029] Reference Figure 1 and Figure 5 A sealing door 16 is hinged at one end of the drying drum 1, and a transparent window 17 is embedded in the center of the sealing door 16. Two sets of support frames 18 are symmetrically fixedly connected to the bottom end of the outer side of the drying drum 1.

[0030] With the above solution, the sealed door 16 with the transparent window 17 prevents the material from leaking out and facilitates the operator to observe the drying status in real time.

[0031] The working principle of the utility model is as follows: when in use, the rotating shaft 3 is passed through the limiting column 7 in the fixing assembly 6 and penetrates the connecting hole 4 so that the end of the rotating shaft 3 is connected to one end of the screen drum 5 for relative rotation, the onion raw material to be dehydrated is placed in the screen drum 5, and the drying fan 11 is started to perform hot air drying and dehydration on the material in the screen drum 5. At the same time, the screen drum 5 rotates synchronously and uniformly under the action of the rotating motor 2 driving the rotating shaft 3 to rotate, and the drying fan 11 blows the raw material upward from the bottom to improve the drying efficiency and speed up the production speed. When the screen drum 5 rotates, the adjusting studs 10 at the upper and lower ends are completely screwed into the screw hole seat 9 so that the two can stably resist the bearing ring 8 sleeved on one end of the outer side of the screen drum 5. The screen cylinder 5 is kept level, and the supporting structure of the bearing ring 8 and the adjusting stud 10 can avoid affecting the stable rotation of the screen cylinder 5. At the same time, when discharging is required, the adjusting stud 10 at the bottom end is screwed out to tilt the screen cylinder 5 toward the discharging end, and the dehydrated onion raw materials can be discharged by tapping the cylinder body. The structure is simple and convenient, reduces the number of motors used, and is easy to maintain. Onion debris that leaks out of the screen cylinder 5 during the drying process can naturally fall on the surface of the curved partition 13 after the drying fan 11 stops discharging air. The material-receiving seal 14 does not hinder the air outlet effect while receiving the material. The curved partition 13 can be easily taken out as a whole for cleaning by screwing out the adjusting stud 10. The curved partition 13 is stably connected to the bottom inner side of the drying cylinder 1 through the slot part 12.
