Description

Technical Field

[0001] This utility model relates to the field of onion processing technology, and in particular to a drying line for onion processing. Background Technology

[0002] Onion processing drying line is a device used for dehydrating and drying onions. After washing, the onions are laid on the drying device and dried, which facilitates the dehydration and drying of the onions.

[0003] Patent document CN208129388U discloses a fine-grained drying device for processing onion powder, including a base and a screening device. A protective cover is fixedly connected to the top of the base. A limiting opening is formed on the left side of the protective cover, and a discharge port is formed on the top of the protective cover. A support frame is fixedly connected to the left side of the base, and a first motor is fixedly connected to the top of the support frame. A turntable is fixedly connected to the output shaft of the first motor, and a connecting rod is hinged to the outer ring of the turntable's front side. This fine-grained drying device for processing onion powder filters the onion powder through a filter screen in the screening device, removing larger particles and improving the texture of the onion powder. A controller controls a heating plate to heat the onion powder, drying it during transportation and making it easier to preserve, thus extending its shelf life.

[0004] The following problems generally exist in the existing technology for drilling holes in ceramic tiles: First, in the existing drying devices, the onions are completely laid flat on the surface of the conveyor belt and dried using a heating device. However, the position of the onions being conveyed is stable, which means that the surface of the onions facing the conveyor belt cannot be completely dried, resulting in poor drying effect. Second, when the onions are laid flat, their side walls are pressed against each other, causing some onions to stick together during drying. This makes the collected onions prone to forming lumps, which is inconvenient for subsequent use and reduces the efficiency of the drying device. Utility Model Content

[0005] This utility model discloses a drying line for onion processing, aiming to solve the technical problems in the prior art where the surface of the onion facing the conveyor belt cannot be completely dried, resulting in poor drying effect and some onions sticking together, causing the collected onions to easily form lumps, which is inconvenient for subsequent use and reduces the efficiency of the drying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drying line for onion processing includes a mesh conveyor and a blowing mechanism. The mesh conveyor is V-shaped with a horizontal bottom. Fixed plates are fixedly installed on the side walls at both ends of the mesh conveyor. Support frames are symmetrically fixedly installed at the bottom of the mesh conveyor, and support columns are symmetrically fixedly installed at the bottom of each support frame. The blowing mechanism is located at the bottom of the mesh conveyor, and a feeding mechanism and a receiving mechanism are fixedly installed at its left and right ends, respectively. Limiting mechanisms are fixedly installed on the side walls of the mesh conveyor belt of the mesh conveyor. A drying mechanism is fixedly installed between the two fixed plates. The blowing mechanism includes a second support plate fixedly installed between two support columns. A first support plate and a base are fixedly installed between adjacent support columns. The base is located below the first support plate, and the second support plate is located above the first support plate. A booster pump is fixedly installed at the upper end of the base. A connecting pipe is fixedly connected to the air outlet of the booster pump. Multiple air pipes are fixedly installed at equal intervals inside the upper end of the connecting pipe. The first support plate and the second support plate are respectively fixedly sleeved on the outside of the connecting pipe.

[0008] Furthermore, the feeding mechanism includes support rods symmetrically fixedly installed on both sides of the mesh conveyor device and located at the left end of the mesh conveyor device. A feeding pipe is fixedly installed between the two support rods, and a hopper is fixedly installed at the upper end of the feeding pipe. A first U-shaped frame is fixedly installed on the top of the hopper. A first rotary motor is fixedly installed at the upper end of the first U-shaped frame. A first rotating rod is rotatably connected inside the top surface of the first U-shaped frame. A spiral blade is fixedly sleeved on the rod wall of the first rotating rod, and the side wall of the spiral blade is in contact with the inner side wall of the feeding pipe. The bottom of the first rotating rod is horizontal with the bottom of the feeding pipe. The output shaft of the first rotary motor passes through the inside of the first U-shaped frame and is fixedly connected to the upper end of the first rotating rod, thereby facilitating the transfer of the onions to be dried into the mesh conveyor device.

[0009] Furthermore, the drying mechanism includes a second U-shaped frame fixedly installed between two fixed plates. Both ends of the second U-shaped frame are fixedly installed with mounting plates. Multiple first heating wires and second heating wires are fixedly installed at equal intervals on the bottom side wall of the mounting plate and the two side walls of the second U-shaped frame. The two mounting plates are parallel to the two ends of the mesh conveyor, thereby facilitating the drying of moving onions.

[0010] Furthermore, the receiving mechanism includes connecting columns symmetrically fixedly installed on both sides of the right end of the mesh conveyor. An arc-shaped block is fixedly installed at the lower end of each of the two connecting columns, and the arc-shaped block is inclined downwards. A protective tube is fixedly installed at the bottom of the protective tube. A third U-shaped frame is fixedly installed at the upper end of the third U-shaped frame. A second rotating rod is rotatably connected inside the top surface of the third U-shaped frame, and multiple connecting rods are fixedly installed at equal intervals at the bottom of the second rotating rod. The output shaft of the second rotating motor passes through the interior of the third U-shaped frame and is fixedly connected to the upper end of the second rotating rod. A cooling mechanism is fixedly installed inside the protective tube, so that the dried onions entering the protective tube can be broken up by the second rotating rod, preventing the onions from sticking together.

[0011] Furthermore, the cooling mechanism is fixedly installed inside the right side wall of the protective tube with a heat dissipation fan, and a filter screen is fixedly installed inside the left side wall of the protective tube. The filter screen and the central axis of the heat dissipation fan are on the same axis. Both sides of the protective tube have through holes, and the filter screen and the heat dissipation fan are respectively set inside the openings, so as to facilitate the cooling of the falling onions.

[0012] Furthermore, the limiting mechanism includes baffles that are fixedly installed at equal intervals on the side wall of the mesh conveyor belt in the mesh transmission device, thereby facilitating the movement of the onion along the mesh conveyor belt.

[0013] As can be seen from the above, the drying line for onion processing provided by this utility model has the following technical effects.

[0014] Firstly, in this invention, after the onions reach the horizontal position at the bottom of the mesh conveyor, a booster air pump can be used to easily blow the onions upwards, causing them to be tossed up and making it easier to flip them over. Then, they are conveyed and dried through the right side of the mesh conveyor, which can improve the uniformity of the onion drying process.

[0015] Secondly, in this invention, when collecting onions, they need to move downwards through the inside of the protective tube, while the second motor drives the second rotating rod to rotate, which facilitates the rotation of the internal connecting rod and disperses the falling onions, preventing them from sticking together and affecting subsequent use.

[0025] Reference Figure 1 and Figure 4A drying line for onion processing includes a mesh conveyor 1 and a blowing mechanism 6. The mesh conveyor 1 is V-shaped with a horizontal bottom. Fixed plates 2 are fixedly installed on the side walls at both ends of the mesh conveyor 1. Support frames 9 are symmetrically fixedly installed on the bottom of the mesh conveyor 1, and support columns 10 are symmetrically fixedly installed on the bottom of each support frame 9. The blowing mechanism 6 is located at the bottom of the mesh conveyor 1, and a feeding mechanism 3 and a receiving mechanism 7 are fixedly installed on its left and right ends, respectively. Limiting mechanisms 4 are fixedly installed on the side walls of the mesh conveyor belt of the mesh conveyor 1. A drying mechanism 5 is fixedly installed between the two fixed plates 2. The blowing mechanism 6 includes a second support plate 66 fixedly installed between the two support columns 10. Furthermore, a first support plate 62 and a base 61 are fixedly installed between adjacent support columns 10. The base 61 is located below the first support plate 62, and the second support plate 66 is located above the first support plate 62. A booster air pump 63 is fixedly installed at the upper end of the base 61. A connecting pipe 64 is fixedly connected to the air outlet of the booster air pump 63. Multiple air pipes 65 are fixedly installed at equal intervals inside the upper end of the connecting pipe 64. The first support plate 62 and the second support plate 66 are respectively fixedly sleeved on the outside of the connecting pipe 64. The upper ends of the air pipes 65 pass through the interior of the second support plate 66 and the first support plate 62, extending to the top of the first support plate 62, and are located below the mesh conveyor belt of the mesh conveyor device 1.

[0026] In this embodiment, when the onion moves to the bottom horizontal position with the mesh conveyor 1, the booster air pump 63 works, so that the blown gas enters the interior of the air pipe 65 through the connecting pipe 64, and blows the gas upward through the air pipe 65, which can blow the onion at this position upward and flip its position, increasing the uniformity of the onion drying.

[0027] In the above technical solution, to facilitate the feeding of onions that need to be dried, the specific operation is as follows:

[0028] Reference Figure 1 and Figure 2In a preferred embodiment, the feeding mechanism 3 includes support rods 32 symmetrically fixedly installed on both sides of the mesh conveying device 1 and located at the left end of the mesh conveying device 1. A feeding pipe 31 is fixedly installed between the two support rods 32, and a hopper 33 is fixedly installed at the upper end of the feeding pipe 31. A first U-shaped frame 34 is fixedly installed at the top of the hopper 33. A first rotary motor 37 is fixedly installed at the upper end of the first U-shaped frame 34. A first rotating rod 35 is rotatably connected inside the top surface of the first U-shaped frame 34. A spiral blade 36 is fixedly sleeved on the rod wall of the first rotating rod 35. The side wall of the spiral blade 36 is in contact with the inner side wall of the feeding pipe 31. The bottom of the first rotating rod 35 is horizontal with the bottom of the feeding pipe 31. The output shaft of the first rotary motor 37 passes through the inside of the first U-shaped frame 34 and is fixedly connected to the upper end of the first rotating rod 35.

[0029] In this embodiment, when feeding the onions, the onions that need to be dried are fed into the inside of the feeding pipe 31 through the hopper 33. At the same time, the first rotary motor 37 is turned on, so that the first rotating rod 35 drives the spiral blade 36 to rotate. This allows the onions placed inside to move downwards with the spiral blade 36, making it easier for them to be moved onto the mesh conveyor belt of the mesh conveyor device 1.

[0030] In the above technical solution, to facilitate the drying of onions, the specific operation is as follows:

[0031] Reference Figure 1 and Figure 3 In a preferred embodiment, the drying mechanism 5 includes a second U-shaped frame 51 fixedly installed between two fixed plates 2. Mounting plates 53 are fixedly installed at both ends of the second U-shaped frame 51. Multiple first heating wires 52 and second heating wires 54 are fixedly installed at equal intervals on the bottom side wall of the mounting plate 53 and the two side walls of the second U-shaped frame 51. The two mounting plates 53 are parallel to each other at both ends of the mesh transmission device 1.

[0032] In this embodiment, when the onions are conveyed onto the mesh conveyor 1, the first heating wire 52 and the second heating wire 54 are turned on, which can conveniently dry the onions that are moving along the mesh conveyor belt in the mesh conveyor 1. At the same time, the second heating wire 54 can dry the onions after they are blown upwards, thus improving the drying efficiency.

[0033] In the above technical solution, to facilitate the collection of dried onions, the specific operation is as follows:

[0034] Reference Figure 1 and Figure 5In a preferred embodiment, the receiving mechanism 7 includes connecting columns 72 symmetrically fixedly installed on both sides of the right end of the mesh conveyor 1. Arc-shaped blocks 71 are fixedly installed at the lower ends of the two connecting columns 72, and the arc-shaped blocks 71 are inclined downwards. A protective tube 76 is fixedly installed at the bottom. A third U-shaped frame 75 is fixedly installed at the upper end of the protective tube 76. A second rotary motor 73 is fixedly installed at the upper end of the third U-shaped frame 75. A second rotating rod 74 is rotatably connected inside the top surface of the third U-shaped frame 75. A plurality of connecting rods 77 are fixedly installed at equal intervals at the bottom of the second rotating rod 74. The output shaft of the second rotary motor 73 passes through the interior of the third U-shaped frame 75 and is fixedly connected to the upper end of the second rotating rod 74. A cooling mechanism 8 is fixedly installed inside the protective tube 76.

[0035] In this embodiment, the dried onions are discharged through the right end of the mesh conveyor 1. At the same time, the second rotary motor 73 is turned on, causing the second rotating rod 74 to drive the connecting rod 77 to rotate. The onions then move through the mesh conveyor to the inside of the inclined arc block 71, where they can easily slide into the inside of the protective tube 76. With the rotation of the connecting rod 77, the falling onions can be easily broken up and then discharged through the bottom of the protective tube 76 for easy collection, preventing the onions from sticking together and affecting subsequent use.

[0036] In the above technical solution, to facilitate the cooling of the dried onions, the specific operation is as follows:

[0037] Reference Figure 1 and Figure 5 In a preferred embodiment, the cooling mechanism 8 is fixedly installed inside the right side wall of the protective tube 76, and a filter 81 is fixedly installed inside the left side wall of the protective tube 76. The central axis of the filter 81 and the cooling fan 82 are on the same axis. Both sides of the protective tube 76 have through holes, and the filter 81 and the cooling fan 82 are respectively disposed inside the openings.

[0038] In this embodiment, when the onion enters the protective tube 76, the cooling fan 82 is turned on, which can conveniently cool the falling onion by blowing air, and the blown hot air can be discharged through the inside of the filter 81.

[0039] In the above technical solution, in order to facilitate the movement of the onion along the inclined mesh transmission device, the specific operation is as follows:

[0040] Reference Figure 1 and Figure 2 In a preferred embodiment, the limiting mechanism 4 includes baffles 41 that are fixedly installed at equal intervals on the side wall of the mesh conveyor belt in the mesh transmission device 1.

[0041] In this embodiment, since the mesh conveyor is V-shaped with both ends inclined, the onion is blocked by the baffle 41 when it is on the mesh conveyor belt to prevent it from slipping, which can effectively make the onion move with the mesh conveyor belt.

[0042] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
