Description
Technical Field
[0001] The utility model relates to the technical field of tea production and processing, and more specifically, to a tea drying oven. Background Art
[0002] The tea making process includes picking, withering, rolling, drying and other steps. The drying process is to stop the oxidation process inside the tea leaves, so as to better maintain the quality and characteristics of the tea leaves. In addition, drying the tea leaves also helps to remove remaining moisture, making it easier to transport and store the tea leaves.
[0003] In the process of drying tea leaves, a tea drying oven is often used. The tea drying oven usually includes a box body, a box door, a hot air blower, a tray and a control switch. There are usually multiple trays, and the trays are usually provided with air holes. In the prior art, people open the box door, then pull out the tray, and then evenly place the tea leaves on the tray, and finally close the box door to dry the tea leaves.
[0004] Since tea is generally processed in large quantities and the space in the tea drying oven is limited, people need to dry the tea in batches. After the previous batch of tea is dried, people need to pull out the tray, then take out the tea in the tray, and then put the undried tea into the tray. In this process, since people need to take out the tea and then put the undried tea in, the operation time is relatively long, and the box body is always kept in contact with the outside air, resulting in more heat loss in the box body, which makes the secondary preheating time of the tea drying oven longer.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model aims to provide a tea drying oven.
[0007] The above technical purpose of the utility model is achieved through the following technical scheme: a tea drying oven comprises a box body, a cavity is formed in the box body, a plurality of square openings connected to the cavity are opened on the box body, a plurality of trays are arranged on the box body, the plurality of trays all pass through the square openings and are slidably connected in the cavity, air holes are opened on the bottom surface of the tray, and insulation plates for covering the square openings are arranged on both end surfaces of the tray, and the insulation plates include a plate 1 and a plate 2 located at the tail of the tray.
[0008] By adopting the above technical solution, when people pull the tray out of the square opening, the plate 2 located at the rear of the tray can better seal the square opening, and the plate 1 on other trays that have not been pulled out can also better seal the square opening, so that all the square openings can be better sealed by the insulation board, and then people take the dried tea leaves out of the tray. During the process of taking the tea leaves, the square opening is always well shielded by the insulation board, so that the time when the inside of the box is connected to the outside air is only the process of people pulling the tray. The process time is short, so that the heat loss inside the box is less.
[0009] The utility model is further configured as follows: the tray comprises a tray frame and a tea tray detachably connected to the tray frame, the air holes are arranged on the bottom surface of the tea tray, the tea tray is used for holding tea leaves, and the first plate and the second plate are both fixedly connected to the tray frame.
[0010] By adopting the above technical solution, after people pull out the tray, they can take the tea tray off the tray rack and take out the tea leaves in the tea tray by dumping, which greatly improves the efficiency of people collecting tea leaves.
[0011] The utility model is further configured as follows: the tray rack is arranged in a rectangular body, the top surface of the tray rack is provided with a square groove for accommodating the tea tray, the inner wall of the tea tray is provided with a drawer groove, and the bottom wall of the square groove is provided with a through groove for exposing the air hole.
[0012] By adopting the above technical solution, after people pull out the tray, they can put their hands into the draw groove. The setting of the draw groove provides people with a better force point when taking the tea tray out of the square groove, making it convenient for people to remove the tea tray from the tray rack. In the subsequent process of drying the tea leaves, the opening of the through groove ensures that the tray rack will not affect the air passing through the pores in the box.
[0013] The utility model is further configured as follows: an embedding groove is opened on the inner wall of the square opening, and a convex block for embedding in the embedding groove is provided at the tail of the disk rack. When the convex block is embedded in the embedding groove, the square opening is covered by the second plate.
[0014] By adopting the above technical solution, when people pull out the tray, the protrusion is embedded in the embedding groove, and the protrusion contacts the inner wall of the embedding groove, so that the tray rack can be better limited and it is not easy for people to completely pull the tray rack out of the square opening. At this time, the second plate can better seal the square opening, so that the heat in the box is not easily dissipated.
[0015] The utility model is further configured as follows: a limiter is arranged in the box body, and when the second plate covers the square opening, the limiter contacts the second plate and provides a force for the rack to move away from the square opening.
[0016] By adopting the above technical solution, when people pull out the tray rack, the tray rack tends to return to the square opening. The setting of the limiter allows the tray rack to be better kept in place, so that the second plate can better seal the square opening, making it difficult for the heat in the box to dissipate, and the subsequent shaking caused by people installing the tea tray will not easily cause the tray rack to return to the square opening.
[0017] The utility model is further configured as follows: the limiter includes two fixing frames and a stop plate located between the two fixing frames, the stop plate is used to interfere with plate 2, a rotating shaft passes through the two fixing frames, the stop plate is rotatably connected to the rotating shaft, and a torsion spring is provided on the rotating shaft.
[0018] By adopting the above technical solution, the setting of the fixed frame and the rotating shaft allows the stop plate to rotate along the rotating shaft, and the torsion spring mounted on the rotating shaft can provide a force for the stop plate to rotate toward plate one. When the stop plate conflicts with plate two, a part of the force applied to the stop plate by the torsion spring is converted into a force to prevent the disc rack from retreating into the square opening, so that plate two can better close the square opening.
[0019] The utility model is further configured as follows: rubber pads are provided on the first plate and the second plate.
[0020] By adopting the above technical solution and setting the rubber pad, the gap between the insulation board and the inner wall of the square opening can be better sealed, so that the air inside and outside the box is not easy to circulate, and the heat inside the box is not easy to dissipate.
[0021] In summary, the utility model has the following beneficial effects: the plate 1 arranged on the tray rack can better seal the square opening, and when people pull the tray out of the square opening, the plate 2 on the pulled out tray rack can better seal the square opening, so that all the square openings can be closed by the insulation plate, and then people take the dried tea leaves out of the tray. In the process of taking the tea leaves, the square opening is always well shielded by the insulation plate, so that the time when the inside of the box is connected to the outside air is only the process when people pull the tray. The process time is short, so that the heat loss inside the box is less, and the tea tray and the tray rack are set to be detachable, so that people can take out the tea leaves in the tea tray by tipping, so that people can collect the dried tea leaves quickly, and the setting of the limiter makes it difficult for the pulled out tray to return to the square opening, so that the plate 2 can better fit the inner wall of the square opening.

DETAILED DESCRIPTION
[0026] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] The tea drying oven comprises a box body and a door rotatably connected to the box body, such as Figure 1 and Figure 2 As shown, a cavity is formed in the box body, and a plurality of square openings 1 connected to the cavity are provided on the box body. The plurality of square openings 1 are distributed in a linear array along the height direction of the box body, and a pallet passes through the plurality of square openings 1. Insulation plates for covering the square openings 1 are fixedly connected to the two end surfaces of the pallet along the depth direction of the square openings 1. The insulation plates are divided into a plate 1 2 and a plate 2 3 located at the tail of the pallet. When the box door is closed, the box door contacts the plate 1 2. The plate 1 2 is provided with a buckle groove for people to pull out the pallet, and the buckle groove is arranged close to the top surface of the plate 1 2.
[0028] like Figure 3 As shown, the tray includes a tray frame 4 and a tea tray 5 detachably connected to the tray frame 4, the tea tray 5 is used to hold tea leaves, a plurality of air holes 16 are provided on the bottom surface of the tea tray 5, the plate 1 2 and the plate 2 3 are fixedly connected to the tray frame 4 by bolts, a draw groove 15 for taking the tea tray 5 out of the tray frame 4 is provided on the inner wall of the tea tray 5, the draw groove 15 is arranged on the two inner walls of the tea tray 5 in the length direction, and a through groove 7 for exposing the air holes 16 is provided on the bottom surface of the tray frame 4.
[0029] like Figure 1 and Figure 2 As shown, an embedding groove 8 is provided on the inner wall of the square opening 1, and a protrusion 9 for embedding in the embedding groove 8 is integrally formed at the tail of the disc rack 4. When the protrusion 9 is embedded in the embedding groove 8, the plate 2 3 covers the square opening 1. A limiter is provided in the box body. When the plate 2 3 covers the square opening 1, the limiter contacts with the plate 2 3 and provides a force for the disc rack 4 to move away from the square opening 1. The limiter includes two fixing frames 10 and a stop plate 11 located between the two fixing frames 10. The stop plate 11 is used to contact with the plate 2 3. The same rotating shaft 12 passes through the two fixing frames 10. The stop plate 11 is rotatably connected to the rotating shaft 12. The rotating shaft 12 is sleeved with a torsion spring 13. The plates 1 2 and 2 3 are provided with rubber pads 14. The rubber pads 14 are used to cover the gap between the insulation board and the square opening 1.
[0030] Working process: when the tea leaves in the tea drying oven are dried, people need to replace the tea leaves in the box. People first wear heat-insulating gloves, then open the box door, and then put their hands into the buckle grooves to pull the tray out of the square opening 1. The setting of the buckle grooves allows people's hands to have a better force point to pull the tray out of the square opening 1. In the process of the tray being pulled out, when the protrusions 9 integrally formed on the tray rack 4 are embedded in the embedded grooves 8, the protrusions 9 collide with the inner walls of the embedded grooves 8, so that the tray rack 4 can be better limited, making it difficult for people to completely pull the tray rack 4 out of the square opening 1. People can more clearly feel the increase in resistance on their hands, which can better remind people that the tray has been pulled out. At this time, the plate 2 3 on the pulled out tray seals the square opening 1 better. The square opening 1 is closed, and the plates 1 2 on other trays that have not been pulled out will better seal the square opening 1, so that all the square openings 1 can be sealed by the heat preservation plate. Then people take the dried tea leaves out of the tray. In the process of taking the tea leaves, the square opening 1 is always well shielded by the heat preservation plate, so that the time when the inside of the box is connected to the outside air is only the process when people pull the tray. This process is short, so that the heat loss inside the box is less. At this time, the twisted torsion spring 13 is released, so that the torsion spring 13 provides a force for the stop plate 11 to rotate toward the tray. The stop plate 11 conflicts with the plate 2 3 under this force, so that the shaking generated when people subsequently install the tea tray 5 is not easy to cause the tray rack 4 to return to the square opening 1, so that the plate 2 3 can better seal the square opening 1.
[0031] Then people put their hands into the extraction groove 15, and then lift the tea tray 5 upwards. The setting of the extraction groove 15 allows people to have a better force application point to remove the tea tray 5 from the tray rack 4. Then people take out the tea leaves in the tea tray 5 by pouring. The tea tray 5 detachably arranged with the tray rack 4 allows people to take out the tea leaves quickly. After pouring out the tea leaves in the tea tray 5, people align the tea tray 5 with the square groove 6 and put it on the tray rack 4. Then people evenly spread the next batch of tea leaves that need to be dried on the tea tray 5. During the subsequent heating process, the hot air can pass through the air holes 16 of the through groove 7 opened on the tray rack 4. Then, the tray is pushed back into the square mouth 1 by hand. The force applied by people on the tray causes the stop plate 11 to rotate away from the tray, and the torsion spring 13 is The stop plate 11 twists, and part of the force people apply to the tray is converted into the stop plate 11 to overcome the rotation force of the torsion spring 13. After the tray is pushed into the square opening 1, the stop plate 11 conflicts with the bottom surface of the tea tray 5, and the plate 1 2 better closes the square opening 1, so that the heat in the box is not easily lost. The rubber pad 14 arranged on the plate 1 2 and the plate 2 3 can better cover the gap between the insulation plate and the inner wall of the square opening 1, so that the air inside and outside the box is not easily connected, further ensuring that the heat in the box is not easily lost. Then people close the box door, and the box door conflicts with the plate 1 2, so that the tray can be better fixed by the box door. Finally, people reopen the tea drying oven. Since the heat loss in the box is less and the temperature is higher, the re-preheating time of the tea drying oven is shorter.
