Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and more particularly to a drying device. Background Technology

[0002] Drying is an important process, mainly aimed at removing moisture from products, shaping them, and facilitating their preservation. There are various methods for drying products. Currently, drying equipment mainly uses hot air to dry products. First, the product is placed on multiple screens, spread evenly to a certain thickness, and then sent into the support frame of the drying equipment for drying.

[0003] Existing drying equipment is well-developed, using built-in heating components and exhaust systems to dry products. These exhaust systems are typically fixed at the top of the drying equipment, from which hot air is expelled. However, due to this fixed location, areas near the exhaust system experience air circulation and lower temperatures, while areas further away have less air circulation and relatively higher temperatures. This results in temperature variations within the drying equipment, ultimately affecting the quality of the dried product. Summary of the Invention

[0051] Please see Figures 1 to 6 This application provides a drying apparatus, comprising:

[0052] A drying chamber 10 is provided inside a drying cavity 13; the drying chamber 10 is provided with an exhaust port 14, which connects to multiple locations of the drying cavity 13;

[0053] The exhaust device 20 has an exhaust passage 21 that communicates with the outside. The exhaust device 20 is adjustablely mounted on the drying chamber 10 to adjust the communication state between the exhaust passage 21 and the exhaust hole 14 so that different positions of the drying chamber 13 can communicate with the outside.

[0054] The drying chamber 10 is used to hold items to be dried. In some embodiments, the drying chamber 10 may include a chamber body 11 and a door 12. The chamber body 11 has a hollow structure inside, and the hollow part of the chamber body 11 is a drying chamber 13. One side of the chamber body 11 has an opening for taking out and placing items to be dried. The door 12 is rotatably disposed on the opening side and is connected to the chamber body 11. Exemplarily, the door 12 is hinged to the chamber body 11.

[0055] Specifically, when products need to be placed or removed, the door 12 is rotated to open, allowing the products to enter and exit the drying chamber 13 through the opening; when drying operations are required, the door 12 is rotated to close, causing the drying chamber 13 to form a sealed cavity. In some embodiments, a sealing ring is provided on the door 12 and / or the chamber 11, and when the drying chamber 13 is sealed, the sealing ring is arranged around the opening. In this application, the product to be dried is tea, and the drying equipment is used to dry the tea; of course, the drying equipment of this application can also be used to dry other products that need to be dried.

[0056] The exhaust vent 14 can be configured as multiple, and the multiple exhaust vents 14 can be placed in one or more of the following locations: the top of the chamber 11, the side wall of the chamber 11, and the door 12; so that the gas in the drying chamber 13 can be discharged from multiple locations.

[0057] The exhaust device 20 has an exhaust channel 21. The exhaust device 20 is adjustablely installed on the drying chamber 10. By adjusting the exhaust channel 21 through the exhaust device 20, the exhaust channel 21 is connected to the exhaust holes 14 at different positions, thereby allowing the gas in the drying chamber 13 to be discharged from the outside through the exhaust holes 14 and the exhaust channel 21 at different positions of the drying chamber 13.

[0058] The exhaust device 20 can adjust the position of the exhaust passage 21 or adjust the opening and closing state of the exhaust passage 21 by means of rotation, translation, etc., thereby adjusting the communication state between the exhaust port 14 and the outside. The specific adjustment methods of the exhaust device will be described in detail below through different embodiments.

[0059] The exhaust channel 21 and the exhaust port 14 work together to expel the gas from the drying chamber 13. During the drying operation, fresh, dry hot air needs to be continuously injected into the drying chamber 13. Since the material to be dried contains a lot of moisture, the moisture will evaporate from the material into the drying chamber 13 during the drying process. When the gas is discharged from the drying chamber 13 through the exhaust channel 21 and the exhaust port 14, the moisture is also discharged, thereby reducing the humidity in the drying chamber 13. This keeps the drying chamber 13 in a relatively low humidity drying condition, which is conducive to the drying of the material and thus improves the quality of the finished product.

[0060] Unlike existing technologies where the drying chamber can only exhaust from a fixed position, in the above technical solution, the position of the exhaust channel 21 is adjusted by the exhaust device 20 so that the exhaust channel 21 is connected to the exhaust holes 14 at different positions. Thus, the gas in different areas of the drying chamber 13 can be discharged through the exhaust holes 14 and the exhaust channel 21, thereby ensuring that the temperature in the drying chamber 13 is close to uniform, so as to improve the drying efficiency and the quality of the items to be dried.

[0061] According to some embodiments of this application, please refer to Figure 3 , Figure 4 The exhaust device 20 is positioned relative to the drying chamber 10 to adjust the connection between the exhaust channel 21 and the exhaust port 14.

[0062] In this embodiment, the exhaust device 20 moves on the drying chamber 10. The exhaust device 20 moves to adjust the position of the gas discharged in the drying chamber 13. That is, the exhaust device 20 blocks the exhaust hole 14 in a certain area, so that the gas in the drying chamber 13 can only be discharged from the exhaust hole 14 that is connected to the exhaust channel 21, thereby achieving exhaust at different positions and ensuring that the temperature in the drying chamber 13 is close to uniform.

[0063] According to some embodiments of this application, please refer to Figures 1 to 4 The exhaust port 14 includes: a plurality of first through holes 141;

[0064] The exhaust device 20 includes an exhaust plate 23 and a first power source 22. The exhaust channel 21 is placed on the exhaust plate 23. The exhaust plate 23 is relatively movable with the drying chamber 10. The first power source 22 is connected to the exhaust plate 23 in a transmission manner. The first power source 22 is used to drive the exhaust plate 23 to move, so that the exhaust channel 21 is connected to different first through holes 141.

[0065] Multiple first through holes 141 are arranged in an array on the chamber body 11, and all of the multiple first through holes 141 penetrate the wall of the chamber body 11 and are connected to the drying chamber 13. An exhaust plate 23 is movably arranged on the chamber body 11. The exhaust plate 23 has an exhaust channel 21, and the area of ​​the exhaust plate 23 without the exhaust channel 21 is used to block the first through holes 141 to prevent gas from escaping from the first through holes 141.

[0066] The exhaust channel 21 passes through the exhaust plate 23, and there is only one exhaust channel 21. By moving the exhaust plate 23, the exhaust channel 21 is aligned with the first through hole 141, so that the gas inside the drying chamber 13 is discharged through the exhaust hole 14 and the exhaust channel 21. Furthermore, when one of the first through holes 141 is aligned with the exhaust channel 21, the exhaust plate 23 blocks the other first through holes 141, so that the internal gas is discharged only from the connection between the exhaust hole 14 and the exhaust channel 21.

[0067] Of course, in other embodiments, there may be multiple exhaust channels 21, and the number of exhaust channels 21 is less than the number of first through holes 141. Multiple exhaust channels 21 may be connected to multiple first through holes 141.

[0068] According to some embodiments of this application, please refer to Figure 1 , Figure 2 as well as Figure 4 The exhaust plate 23 is circular, and the exhaust plate 23 rotates around its center. The plurality of first through holes 141 are arranged in a ring array around the center of the exhaust plate 23.

[0069] The first power source 22 is used to drive the exhaust plate 23 to rotate, so that the exhaust channel 21 on the exhaust plate 23 is connected to the first through hole 141 at different positions.

[0070] In this embodiment, the exhaust plate 23 is circular, and a plurality of first through holes 141 are arranged in a ring on the drying chamber 10. The center of the exhaust plate 23 coincides with the circle of the ring array of first through holes 141, and the distance from the center of the exhaust plate 23 to the exhaust channel 21 is equal to the distance from the center of the ring array to the first through hole 141. The center of the exhaust plate 23 is rotatably connected to the top of the chamber body 11, and the exhaust plate 23 rotates around the center, while the exhaust channel 21 located on the exhaust plate 23 rotates synchronously.

[0071] To improve exhaust efficiency, the diameter of the exhaust channel 21 is equal to the diameter of the first through hole 141. The gas exhaust efficiency is optimal when the first through hole 141 is aligned with the exhaust channel 21.

[0072] Of course, in some embodiments not shown, the first through hole 141 can also be arranged in a straight line, the exhaust plate 23 is strip-shaped, the exhaust plate 23 is slidably disposed on the drying chamber 10, and the exhaust channel 21 is disposed through the strip-shaped exhaust plate 23; by driving the exhaust plate 23 to translate, the exhaust channel 21 located on the exhaust plate 23 is connected to the first through hole 141 on the drying chamber 10, thereby causing one of the first through holes 141 to open for exhaust.

[0073] According to some embodiments of this application, please refer to Figures 1 to 2 The outer edge of the circular exhaust plate 23 has teeth 231, and the output end of the first power source 22 is fitted with a gear 221, which meshes with the teeth 231 on the outer edge of the exhaust plate 23.

[0074] The exhaust plate 23 has teeth 231 on its outer edge, and a gear 221 is fitted onto the output end of the first power source 22, meshing with the exhaust plate 23. When the first power source 22 drives the gear 221 to rotate, the gear 221 drives the exhaust plate 23 to rotate around the center, thereby connecting the exhaust channel 21 with the first through hole 141 at different positions. The first power source 22 is a driving component used to provide power for rotation or movement.

[0075] In other implementations, the output end of the first power source 22 can be directly connected to the center of the exhaust plate 23, that is, the first power source 22 directly drives the exhaust plate 23 to rotate.

[0076] According to other embodiments of this application, please refer to Figures 5 to 6 The exhaust device and the drying chamber have another relative movement and cooperation mode. Specifically, the exhaust device 20 is movably embedded in the exhaust hole 14 and the exhaust device 20 covers the exhaust hole 14.

[0077] The movement of the exhaust device 20 in the exhaust port 14 causes the exhaust channel 21 to change position and connect different positions of the drying chamber 13.

[0078] In this embodiment, the exhaust device 20 is embedded in the exhaust hole 14. The position of the exhaust channel 21 is adjusted by the exhaust device 20 to change the specific exhaust position of the exhaust hole 14. That is, the exhaust channel passes through the exhaust hole and directly connects the drying chamber to the outside. By adjusting the position of the exhaust channel by the exhaust device 20, different positions of the drying chamber 13 are connected to the outside.

[0079] According to some embodiments of this application, please refer to Figures 5 to 6 The drying chamber 10 has a first plate 25 and a second plate 26 spaced apart from each other. The exhaust port 14 passes through the first plate 25 and the second plate 26. The exhaust device 20 includes a movable plate 24 and the exhaust channel 21 is placed on the movable plate 24.

[0080] A hollow interlayer 27 for accommodating the movable plate 24 is provided between the first plate 25 and the second plate 26, and the movable plate 24 is movably disposed in the hollow interlayer 27; when the movable plate 24 moves in the hollow interlayer 27, it drives the exhaust channel 21 to move in the exhaust hole 14.

[0081] Furthermore, in some embodiments, the thickness of the movable plate 24 is less than or equal to the distance between the first plate 25 and the second plate 26.

[0082] The first plate 25 and the second plate 26 have the same shape and structure, and the vent 14 passes through the first plate 25 and the second plate 26. The first plate 25 and the second plate 26 are spaced apart, that is, the space between the first plate 25 and the second plate 26 is a hollow interlayer 27, and the vent 14 on the first plate 25 and the vent 14 on the second plate 26 are directly opposite each other.

[0083] The height of the hollow interlayer 27 is greater than or equal to the thickness of the movable plate 24. The movable plate 24 is placed within the hollow interlayer 27. The length of the movable plate 24 is less than the length of the hollow interlayer 27, and / or the width of the movable plate 24 is less than the width of the hollow interlayer 27. Preferably, the height of the hollow interlayer 27 is equal to the distance between the first plate 25 and the second plate 26 to prevent the gas in the drying chamber 13 from pushing up the movable plate 24, thereby preventing air leakage in the drying chamber 13. The length and width of the movable plate 24 are both greater than the diameter of the exhaust hole 14, thereby enabling the movable plate 24 to move within the hollow interlayer 27.

[0084] According to some embodiments of this application, the exhaust device includes: a second power source; the second power source is connected to the movable plate in a transmission manner, and the second power source is used to drive the movable plate to move.

[0085] The second power source is used to drive the movable plate 24 to move, so that the exhaust channel 21 on the movable plate 24 moves together with the movable plate 24, so that different positions of the drying chamber 13 are connected to the outside and the gas is discharged.

[0086] According to some embodiments of this application, please refer to Figure 5 The movable plate 24 rotates around the center of the exhaust hole 14, and the exhaust channel 21 is positioned between the center of rotation and the edge of the exhaust hole 14. That is, the exhaust channel 21 is eccentrically positioned on the movable plate 24, so the position of the exhaust channel 21 can be changed when the movable plate 24 rotates.

[0087] Specifically, the movable plate 24 is circular, and the diameter of the movable plate 24 is larger than the diameter of the exhaust hole 14; the center of the circular movable plate 24 coincides with the center of the exhaust hole 14, and the exhaust channel 21 is eccentrically set on the circular exhaust plate 23; that is, when the movable plate 24 rotates around the center, the movement trajectory of the exhaust channel 21 is circular.

[0088] In some embodiments, the movable plate 24 is circular, and the rotation center of the movable plate 24 is located on one side of the center of the circle of the movable plate 24, and the movable plate 24 rotates around the rotation center.

[0089] Of course, in other embodiments, the movable plate 24 can be of any shape, as long as it continuously covers the exhaust hole 14 during rotation. Alternatively, the exhaust plate 23 can move in any direction, as long as the edge of the movable plate 24 does not intersect with the edge of the exhaust hole 14 during movement.

[0090] It should also be noted that the exhaust channel can be a tubular structure or a through hole. When the exhaust channel is a tubular structure, it is open at both ends and hollow in the middle, allowing gas to move from one end to the other. Of course, in some embodiments, the tubular structure can be a straight pipe (e.g., Figures 5 to 6 As shown in the figure, it can also be an L-shaped tube (not shown in the figure). The bent end of the L-shaped tube is placed in the drying chamber to expand the exhaust area.

[0091] In the above embodiments, the adjustment of the exhaust device is achieved through the relative movement between the exhaust device and the drying chamber. However, according to some embodiments of this application (not shown), the exhaust device itself can also be adjusted through changes in its state, thereby adjusting the connection between the exhaust channel and the exhaust port.

[0092] Specifically, the exhaust port 14 includes a plurality of second through holes, which are located at multiple positions in the drying chamber 10; the exhaust device 20 includes a plurality of valves, which correspond one-to-one with the plurality of second through holes, and the valves are used to adjust the connection state of the second through holes.

[0093] The second through-hole can be located at one or more of the following positions: the top of the drying chamber 10, the bottom of the drying chamber 10, and the side wall of the drying chamber 10; the opening and closing states of multiple second through-holes can be controlled by setting valves in the second through-holes. Specifically, when the temperature value and / or pressure value in a certain area is greater than a preset pressure value, the valve in the corresponding area is opened; of course, in some embodiments, the valves can also be opened sequentially at preset intervals.

[0094] The valve includes a valve body and a valve core. The valve body's channel forms an exhaust channel 21, and the valve body is placed in the exhaust port. The valve core controls the opening and closing of the exhaust channel 21, thereby controlling the opening and closing state of the exhaust port 14. In this embodiment, the opening and closing state of the exhaust port 14 can be controlled by adjusting the valve core to change the valve's opening and closing state. By adjusting the valves at different positions of the second through-hole, exhaust can be achieved in different areas of the drying chamber 13, thereby making the temperature in the drying chamber 13 more uniform.

[0095] According to some embodiments of this application, the exhaust device 20 adjusts the connection between the exhaust channel 21 and the exhaust hole 14 at preset time intervals, so that different positions of the drying chamber 13 are connected to the outside at preset time intervals. For example, in the embodiment described above that uses a first power source to drive the movable plate 24 to rotate, the first power source can be controlled to open at preset time intervals and drive the movable plate 24 to rotate; in the embodiment that uses a valve, the valve core can be controlled to open at preset time intervals, so that the exhaust channel 21 is open, thereby discharging the gas in the drying chamber 13.

[0096] In existing drying equipment, there is only one exhaust port 14, which is fixedly located at the top of the drying equipment. When the drying operation begins, the gas is discharged from the exhaust port 14 at the top. However, since some gas is located in the dry chamber 13 where the gas flow is not smooth, the gas in that area is not easily discharged, which affects the drying efficiency and the quality of the dried product. In this application, the exhaust port 14 connects multiple locations in the dry chamber 13, so that gas from different areas can be discharged from the dry chamber 13.

[0097] In practical use, since the exhaust channel 21 is connected to the exhaust port 14 at preset intervals, when the exhaust port 14 is not connected to the exhaust channel 21, the air supply equipment continues to operate, and the internal temperature of the drying chamber 13 is higher than the outside temperature. When the exhaust port 14 is connected to the exhaust channel 21, the gas in the drying chamber 13 can be quickly discharged from the connection between the exhaust channel 21 and the exhaust port 14; the hot air entering the drying chamber 13 can quickly move to all parts of the drying chamber 13, thereby making the temperature uniform throughout the drying chamber 13. When the exhaust port 14 closes again, the air supply equipment can quickly replenish the drying chamber 13 with dry hot air after the gas is discharged.

[0098] It should also be noted that the air supply equipment can be an air pump or a blower. After the gas in the drying chamber 13 is discharged through the air supply hole and the exhaust channel, the air supply equipment can quickly deliver hot air to various locations in the drying chamber 13.

[0099] After a preset time interval, the exhaust channels 21 at different positions can be sequentially connected to the exhaust holes 14 to discharge gas from different positions, thereby ensuring a uniform temperature in the drying chamber 13. Alternatively, in other embodiments, multiple pressure, humidity, and / or temperature sensors can be installed in the drying chamber 13. When a sensor detects an excessively high value, the exhaust device 20 at the corresponding position can be adjusted.

[0100] According to some embodiments of this application, the exhaust port 14 is located at the top of the drying chamber 10. That is, the exhaust port 14 is disposed through the top of the drying chamber 10.
