Description

Technical Field

[0002] Oil-tea camellia seeds, also known as camellia seeds, are the fruits of the oil-tea camellia tree and are mainly used to produce camellia seed oil. During production, the oil-tea camellia seeds are pressed by a physical pressing method to extract the oil in the seeds.

[0003] Before pressing, the oil-tea camellia seeds need to be dried to reduce the moisture content in the seeds. At present, for drying the oil-tea camellia seeds, a dryer is often used. However, during drying, hot air dries the oil-tea camellia seeds from bottom to top, and the hot air drives the moisture in the seeds to transpire upward. At this time, the oil-tea camellia seeds located below are better dried, while the oil-tea camellia seeds located above not only receive less hot air but also are affected by the moisture transpiring from below, which affects the drying effect.

[0028] The following is combined with Figures 1-8 This application is described in further detail.

[0029] The present application embodiment discloses a tea seed drying machine. Figure 1 The dryer comprises a body 1, the outer wall of the body 1 is fixedly connected with a drying box 2, the drying boxes 2 are multiple and symmetrically arranged, a drying slot 21 is opened in the drying box 2, and the notch of the drying slot 21 is located at the top of the drying box 2. In the embodiment of the present application, there are two drying boxes 2.

[0030] See also Figure 1 and Figure 2, a blowing groove 11, a heating groove 12, a combustion groove 13 and a ventilation groove 14 are arranged in the machine body 1 from top to bottom, and the blowing groove 11, the heating groove 12, the combustion groove 13 and the ventilation groove 14 are interconnected. The machine body 1 is provided with a feeding port communicating with the combustion groove 13, and wood is put into the combustion groove 13 through the feeding port; a furnace door is hinged to the machine body 1, and the feeding port is closed by the furnace door when the wood is burning. The machine body 1 is fixedly connected with a heating plate 15, the heating plate 15 is in an arc plate structure, and the heating plate 15 is located between the heating groove 12 and the combustion groove 13. The machine body 1 is fixedly connected with a support net 16, and the support net 16 is located between the combustion groove 13 and the ventilation groove 14. The machine body 1 is fixedly connected with a smoke exhaust pipe 17, one side pipe orifice of the smoke exhaust pipe 17 communicates with the combustion groove 13, and the other side pipe orifice penetrates through the machine body 1 and extends upward.

[0031] During the drying work, the wood is placed on the top of the support net 16 and ignited. At this time, the air inlet of the ventilation groove 14 provides oxygen to assist combustion and heating for the wood. The smoke generated when the wood burns is discharged from the smoke exhaust pipe 17, and the heating plate 15 is heated when the wood burns, so that the air temperature in the heating groove 12 rises.

[0032] In the machine body 1 and the wall of the drying box 2, air delivery holes 18 which are interconnected are respectively arranged. One side orifice of the air delivery hole 18 communicates with the drying groove 21 and is located at the bottom of the drying groove 21, and the other side orifice of the air delivery hole 18 communicates with the heating groove 12 and is located at the bottom of the heating groove 12.

[0033] The dryer further includes a blower fan 19, the blower fan 19 is fixedly connected to the machine body 1 and is located in the blowing groove 11. The machine body 1 is provided with an air inlet 111, the air inlet 111 communicates with the blowing groove 11, and the air inlet 111 is located above the blower fan 19. When the blower fan 19 is started, external air enters the blowing groove 11 through the air inlet 111, and then the blower fan 19 drives the air to form an air flow blowing towards the heating plate 15. Then the air flow flows along the arc convex surface side of the heating plate 15 towards the air delivery hole 18; when the air flow flows in the heating groove 12, the temperature of the air flow rises; finally, the heated air flow flows into the drying groove 21 through the air delivery hole 18 for drying the oil tea seeds.

[0034] See Figure 2 And Figure 3 , the drying box 2 is fixedly connected with a support plate 22, and the support plate 22 is located in the drying groove 21 and is adjacent to the orifice of the air delivery hole 18. The drying box 2 is fixedly connected with a bearing plate 23, the bearing plate 23 is located in the drying groove 21 and is above the support plate 22, and there are multiple bearing plates 23 which are evenly spaced up and down. The bearing plate 23 is provided with air permeation holes 24, and there are multiple air permeation holes 24 which are evenly spaced. The bearing plate 23 is provided with a feeding port 231, and the feeding ports 231 of the upper and lower adjacent bearing plates 23 are aligned with each other.

[0035] See Figure 3 AndFigure 4 , a hinge shaft 237 is rotatably connected to the top of the support plate 22 and the top of the bearing plate 23. The hinge shaft 237 is located at a position away from the feed inlet 231. A toggle plate 238 is fixedly connected to the outer peripheral side of the hinge shaft 237. A communication hole 2381 is formed in the toggle plate 238. There are a plurality of communication holes 2381 which are evenly spaced. Power springs 239 are respectively installed and fixed on the support plate 22 and the bearing plate 23. The top of the power spring 239 abuts against the bottom of the toggle plate 238 and at a position away from the hinge shaft 237. When the power spring 239 elastically releases, it drives the toggle plate 238 to flip upwards. One end of the side of the toggle plate 238 away from the hinge shaft 237 is fixedly connected with a sealing plate 2382. The sealing plate 2382 extends vertically downwards. Sliding grooves are respectively formed in the tops of the support plate 22 and the bearing plate 23. The sealing plate 2382 slides up and down in the sliding grooves. The power spring 239 is located between the sealing plate 2382 and the hinge shaft 237.

[0036] A discharge pipe is fixedly connected to the outer wall of the drying box 3,232 and on the side away from the feed inlet 231. A discharge port 211 is formed in the wall of the drying box 2. The discharge port 211 covers the upper and lower bearing plates 23 and the support plate 22. The discharge port 211 is communicated with the discharge pipe. A closing plate 212 is slidably connected to the wall of the drying box 2 up and down. The closing plate 212 is used to control the opening and closing of the discharge port 211. A guiding surface 2383 is obliquely formed in the toggle plate 238. The guiding surface 2383 is adjacent to the discharge port 211 and faces the discharge port 211.

[0037] Before drying, the oil-tea seeds are put into the feed inlet 231, and then the oil-tea seeds fall onto the lowermost toggle plate 238 along the feed inlet 231. Then when the oil-tea seeds fill the lowermost toggle plate 238 and the adjacent upper bearing plate 23, the oil-tea seeds continue to enter the adjacent upper toggle plate 238, and so on. The oil-tea seeds continue to fill the toggle plate 238 and the adjacent upper bearing plate 23 until the oil-tea seeds cover the uppermost toggle plate 238. The toggle plate 238 flips downwards under the gravity of the oil-tea seeds. At this time, the power spring 239 enters a compressed state. After that, the air flow entering the drying tank 21 through the air injection holes 18 (the air injection holes 18 are marked in Figure 2 flows upwards, continuously drying the oil-tea seeds on the top of the toggle plate 238. When the drying of the oil-tea seeds is completed, the closing plate 212 is slid upwards to open the discharge port 211. At this time, the oil-tea seeds enter the discharge port 211 along the guiding surface 2383 and are discharged along the discharge pipe. At the same time, when the oil-tea seeds on the toggle plate 238 close to the discharge port 211 are discharged, the power spring 239 elastically releases, pushing the toggle plate 238 to flip upwards, so that the oil-tea seeds continuously approach the discharge port 211 and are discharged.

[0038] See Figure 2 And Figure 4, chute 221 is respectively formed in the support plate 22 and the bearing plate 23, and the chute 221 extends in the horizontal direction. A first communication hole 25 is formed in the side wall of the drying box 2, and the first communication hole 25 extends in the vertical direction. The two ends of the first communication hole 25 are respectively communicated with the adjacent upper and lower chutes 221, and the adjacent upper and lower first communication holes 25 are arranged oppositely. A second communication hole 26 is formed in the wall of the drying box 2, and the second communication hole 26 extends in the vertical direction. The second communication hole 26 communicates the uppermost chute 221 and the lowermost chute 221.

[0039] A filter cloth 4 is slidably penetrated through the wall of the drying box 2. The filter cloth 4 is connected end to end and is slidably penetrated through the chute 221, the first communication hole 25 and the second communication hole 26. When the air flow in the drying tank 21 moves upward, the air flow passes through the filter cloth 4. At this time, the filter cloth 4 absorbs the water vapor evaporated when the air flow dries the oil-tea camellia seeds, which is beneficial to reducing the water content in the upward flowing air flow and improving the drying effect of the oil-tea camellia seeds.

[0040] See Figure 5 , a plurality of rotating grooves 27 are formed in the wall of the drying box 2. The rotating grooves 27 are respectively communicated with the first communication hole 25 and the second communication hole 26, and the rotating grooves 27 are respectively located on the side of the first communication hole 25 and the second communication hole 26 close to the bearing plate 23. A rotating shaft 271 is rotatably connected to the drying box 2, and the rotating shaft 271 is located in the rotating groove 27. The filter cloth 4 is slidably connected to the outer peripheral side wall of the rotating shaft 271, which is convenient for the filter cloth 4 to slide and reduces the friction force when the filter cloth 4 slides.

[0041] See Figure 6 And Figure 7 , an installation groove 28 is formed in the wall of the drying box 2, and the installation groove 28 is communicated with the air outlet hole 18. A rotating shaft 281 is rotatably connected to the drying box 2, and the rotating shaft 281 extends into the installation groove 28. A power blade 282 is fixedly connected to the outer peripheral side of the rotating shaft 281. There are a plurality of power blades 282 and they are evenly spaced along the circumferential direction. The power blade 282 extends into the air outlet hole 18. When the air flow enters the drying tank 21 through the air outlet hole 18, the air flow impacts on the power blade 282, driving the rotating shaft 281 to rotate.

[0042] See Figure 6 And Figure 8 , the drying box 2 is provided with a driving assembly. When the rotating shaft 281 rotates, the driving assembly drives the filter cloth 4 to slide, so that the uppermost filter cloth 4 can move to the lowermost. At this time, when the air flow passes through the filter cloth 4, it can drive a small amount of water in the filter cloth 4 to evaporate and contact the oil-tea camellia seeds located below, reducing the possibility of filtration and drying of the oil-tea camellia seeds located below, which is beneficial to improving the drying uniformity of the oil-tea camellia seeds.

[0043] See Figure 6 AndFigure 7 , the driving assembly includes a driving roller 31 and a driving belt 32. The driving rollers 31 are symmetrically arranged up and down. A driving groove 29 is formed in the drying box 2. The driving groove 29 is adjacent to the support plate 22. The driving rollers 31 correspond to the driving grooves 29 one by one and are located in the driving grooves 29. The driving rollers 31 are rotatably connected to the drying box 2. The filter cloth 4 passes through between the driving rollers 31 that are opposite up and down, and the filter cloth 4 is slidably connected to the driving rollers 31. When the driving rollers 31 rotate, the filter cloth 4 is driven to slide through friction. A driving shaft 311 is coaxially fixed to the end of the driving roller 31. The driving belt 32 is connected end to end and sleeved between one of the driving shafts 311 of the lower driving roller 31 and the rotating shaft 281. When the rotating shaft 281 rotates, the driving belt 32 drives the driving roller 31 to rotate, so that the filter cloth 4 enters a sliding state.

[0044] See Figure 6 And Figure 8 , the driving roller 31 is provided with a hollow. Connecting gears 3 are respectively fixedly connected to one of the driving shafts 311 of the upper and lower driving rollers 31. The upper and lower connecting gears 3 are located on the same side, and the connecting gears 3 of the upper and lower driving rollers 31 are meshed with each other. When rotating, a part of the filter cloth 4 is squeezed into the driving roller 31 by the extrusion force between the upper and lower driving rollers 31, improving the ability of the driving roller 31 to drive the filter cloth 4 to slide.

[0045] See Figure 5 And Figure 6 , at the same time, in order to reduce the amount of moisture in the filter cloth 4, connecting rings 312 are respectively rotatably connected to the outer peripheral sides of the driving shafts 311 on both sides of the upper driving roller 31. The connecting rings 312 slide up and down in the drying box 2. The drying box 2 is fixedly connected with driving springs 313. The driving springs 313 correspond to the connecting rings 312 one by one, and the driving springs 313 are located above the connecting rings 312. The bottom of the driving spring 313 is fixedly connected to the top outer wall of the connecting ring 312, and the bottom of the driving spring 313 is fixedly connected to the drying box 2. When the driving spring 313 elastically releases, it drives the connecting ring 312 to move downward, increasing the extrusion force of the driving roller 31 on the filter cloth 4. At this time, the driving roller 31 squeezes out the moisture in the filter cloth 4, and the squeezed moisture flows downward; at the same time, when the filter cloth 4 passes through the first communication hole 25 and the second communication hole 26, the heat of the hot air in the drying groove 21 for drying the inner wall of the drying box 2 can heat the filter cloth 4, reducing the amount of moisture in the filter cloth 4.

[0046] See Figure 5 And Figure 6, the drying box 2 is fixedly connected with a wiper 314. The wiper 314 is located in the driving groove 29, and the wiper 314 is slidably connected to the outer peripheral side wall of the lower driving roller 31. The drying box 2 is provided with a drain hole 291. The bottom side hole of the drain hole 291 is located on the outer wall of the drying box 2, and the top side hole of the drain hole 291 is located on the bottom wall of the lower driving groove 29. The drain hole 291 is communicated with the driving groove 29. The drying box 2 is detachably fixed with a control board 292, and the control board 292 can control the opening and closing of the drain hole 291.

[0047] The filter cloth 4 is extruded to make water flow on the outer wall of the driving roller 31. At this time, the wiper 314 scrapes off the water adhering to the outer wall of the driving roller 31, and the scraped water condenses into water droplets and flows downward to gather on the control board 292. At this time, remove the control board 292 and open the drain hole 291 to drain the gathered water droplets.

[0048] The bearing plate 23 is rotatably connected with a power shaft 232, and the power shaft 232 is located below the sliding groove 221. The bearing plate 23 is slidably penetrated with a driving belt 233. The driving belt 233 is connected end to end, and the driving belt 233 is sleeved on the outer peripheral sides of the power shaft 232 and the driving shaft 311. When the power shaft 232 rotates, it drives the driving belt 233 to slide in a cycle. A plurality of ventilation holes 235 are evenly spaced on the driving belt 233, and hot air continuously flows upward through the ventilation holes 235. The inner wall of the lower driving belt 233 is slidably connected to the bottom outer wall of the bearing plate 23. The outer peripheral side of the driving belt 233 is fixedly connected with driving bristles 234, and there are a plurality of driving bristles 234 and they are evenly spaced. The box wall of the drying box 2 is slidably penetrated with a linkage belt 236 (the linkage belt 236 is marked in Figure 8 ), and the linkage belt 236 is connected end to end and sleeved on the adjacent rotating shaft 271 and the power shaft 232.

[0049] When the filter cloth 4 slides, it drives the rotating shaft 271 to rotate. At this time, the rotating shaft 271 drives the power shaft 232 to rotate through the linkage belt 236 (the linkage belt 236 is marked in Figure 8 ), so that the driving bristles 234 stir the oil tea seeds to stir the oil tea seeds and improve the drying effect of the oil tea seeds.

[0050] The implementation principle of an oil tea seed dryer in an embodiment of the present application is: Before drying, the oil-tea camellia seeds are sent into the drying tank 21, so that the oil-tea camellia seeds move to the top of the support plate 22 and the bearing plate 23 through the feed inlet 231. Then, the wood is placed into the combustion tank 13 and ignited. Then, the blower fan 19 is started, so that the air flow enters the heating tank 12. At this time, the air flow is heated and then flows into the drying tank 21 through the air delivery holes 18. Then, the air flow flows upward to dry the oil-tea camellia seeds. During drying, the hot air passes through the filter cloth 4, and the filter cloth 4 keeps sliding, which can reduce the amount of moisture in the air flow for drying the oil-tea camellia seeds located above, and improve the drying speed of the oil-tea camellia seeds.

[0051] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
