Description

Technical Field

[0001] The invention relates to the technical field of tea drying, in particular to a uniform heating control device for drying tea. Background Art

[0002] The uniform heating control device for tea drying is an important device to ensure that the tea is heated evenly during the drying process and to avoid local overheating or uneven drying. This device usually combines a heating system, a ventilation system, and a control system to achieve precise control of the temperature and humidity in the drying room, thereby ensuring the quality and taste of the tea.

[0003] However, compared with the prior art, there are still the following defects in specific use:

[0004] 1. In the prior art, a hot air blower is usually installed above the drying box to directly deliver hot air to the tea leaves. First, the drying method of delivering hot air from top to bottom will cause a temperature gradient to form inside the drying box. The hot air gradually cools down during the descent process, so that the upper layer of tea leaves receive more heat than the lower layer, resulting in different drying degrees of tea leaves in different layers. This uneven temperature distribution directly affects the final quality of the tea leaves, causing some tea leaves to be over-dried and lose their flavor, while other parts will not be able to achieve ideal storage conditions due to insufficient drying;

[0005] 2. In order to effectively terminate the residual heat effect of tea leaves caused by high-temperature drying, the existing technology uses two main ways to achieve the cooling of tea leaves: natural cooling and mechanical assisted cooling. First, the natural cooling method uses the air convection and heat exchange mechanism naturally formed in the room to gradually release the heat accumulated inside the tea leaves. Although this method does not require additional energy consumption, it has significant disadvantages in that the cooling time is long and the efficiency is low. The slow heat loss rate prolongs the overall production cycle, affecting production efficiency and capacity. Special cooling mechanical equipment, such as high-efficiency fans or cooling fan systems, is used. These devices accelerate the heat convection and heat radiation process on the surface of the tea leaves by forcing air flow, which not only increases the initial purchase cost, but also generates additional expenses in subsequent operation and maintenance, which puts economic pressure on some producers with limited resources.

[0006] In view of this, the present invention proposes a uniform heating control device for drying tea leaves to compensate for and improve the deficiencies of the prior art. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a uniform heating control device for drying tea leaves to solve the technical problems raised in the above background technology.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is: a uniform heating control device for drying tea leaves, comprising a drying box body, a compressor is installed on the upper surface of the drying box body, a controller is installed on the front side of the compressor, a processing rack is installed inside the drying box body, uniform drying mechanisms are arranged on the left and right sides of the drying box body, and a processing oscillation mechanism is arranged inside the drying box body;

[0009] The uniform drying mechanism is used to uniformly dry the tea leaves in the drying box body and to cool them in time;

[0010] The processing vibration mechanism is used to irregularly vibrate the tea raw materials, thereby cooperating with the drying process of the tea raw materials.

[0011] Furthermore, the uniform drying mechanism includes an air pipe connected to both sides of the compressor, the end of the air pipe away from the compressor is connected to a limiting bin, the inner wall of the limiting bin is fixedly connected with a sealing ring, the side of the sealing ring close to the drying box body is fixedly connected with a swirl plate, the surface of the swirl plate is connected to a vortex tube, and the inner wall of the vortex tube is fixedly connected with a diverter plate.

[0012] Furthermore, the side of the limit bin away from the drying box body is connected to a recovery curved pipe, the lower end of the recovery curved pipe is connected to a storage cylinder, a check valve is installed inside the storage cylinder close to the drying box body, and the end of the storage cylinder away from the recovery curved pipe is connected to a nozzle.

[0013] Furthermore, the sealing ring is composed of two components, a disc and a cylinder, and the overall size of the disc is equal to the inner diameter of the limiting bin, while the overall size of the cylinder is equal to the size of the swirl sheet.

[0014] Furthermore, the vortex tube is distributed in three sections as a whole, and the middle connecting part of the vortex tube is funnel-shaped as a whole.

[0015] Furthermore, the splitter plate is in the shape of a three-dimensional isosceles triangle as a whole, and exhaust holes are evenly penetrated through the surface of the vortex tube at positions corresponding to the inclined surface of the splitter plate.

[0016] Furthermore, the processing oscillation mechanism includes a positioning frame fixedly connected to the inside of the drying box body, the positioning frame is rotatably connected to the processing rack, the surface of the positioning frame is evenly and symmetrically fixedly connected with a fixed shell, the inner wall of the fixed shell is evenly provided with curved grooves, the outer wall of the processing rack is evenly and fixedly connected with a double-layer sleeve plate, and the outer wall of the double-layer sleeve plate is evenly and fixedly connected with a spring.

[0017] Furthermore, the fixed shell is in an incomplete arc shape as a whole, cylindrical protrusions are fixedly connected to the outer wall of the processing frame at positions corresponding to the curved grooves, and the spring is rotationally connected to the processing frame through the cylindrical protrusions and the curved grooves.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) In order to solve the problem of uneven drying caused by temperature gradient inside the traditional drying box, the present device transforms the flow mode of compressed air into high-speed rotating vortex through the structural design of the swirl plate, so that the air molecules rely on friction and collision to generate energy separation and thus increase their temperature. In combination with the structural position of the subsequent splitter plate and vortex tube, it ensures that the hot air flow can directly and efficiently act on each layer of tea raw materials on the processing rack. The structural characteristics of the vortex tube itself also achieve uniform diffusion and vertical penetration of the hot air flow. Compared with the one-way transmission method of the traditional hot air blower from top to bottom, the vortex tube technology effectively avoids the heat attenuation and uneven distribution of the hot air flow during the descending process, so that each layer of tea can receive similar drying conditions, thereby ensuring the uniformity and stability of the drying effect;

[0020] (2) At the same time, during the drying stage, the vortex tube divides the input compressed air into two parts with completely different temperatures: the high-temperature airflow on the outside is used to dry the tea leaves, while the low-temperature airflow in the center is collected into the storage cylinder through the recovery curved tube. This process not only realizes the efficient supply of heat required for drying, but also stores the originally lost low-temperature energy, providing a cold source for subsequent cooling treatment. When the drying process is successfully completed, the cold airflow in the storage cylinder can be introduced into the tea processing area by simply operating the check valve, and the tea leaves can be quickly cooled. This design of heat energy recycling not only reduces heat emissions to the external environment, but also significantly improves the overall energy utilization efficiency;

[0021] Compared with the natural cooling method, this device significantly shortens the cooling time, improves production efficiency and capacity, and the cold air flow can promote the rapid dissipation of heat inside the tea leaves, thereby avoiding the problem of tea quality degradation caused by local overheating. In addition, this device also avoids the high energy consumption and high cost problems in the mechanical assisted cooling method, and reduces the overall energy consumption and operating costs by recycling heat energy;

[0022] (3) Through the coordinated action of the fixed shell, curved groove and spring, the tea leaves are fully turned and dispersed during the drying process. This dynamic adjustment not only increases the contact area between the tea leaves and the hot air, thus improving the heat transfer efficiency, but also promotes the rapid evaporation and discharge of the water inside the tea leaves. Compared with the traditional mechanical stirring method, the device can significantly shorten the drying time and improve the drying efficiency, thereby reducing production costs and energy consumption. The device effectively avoids the accumulation and overheating of the tea leaves during the drying process by adjusting the position and distribution of the tea leaves in real time, thus ensuring that the tea leaves are evenly heated and properly dried during the drying process.

[0035] Embodiments of the present invention

[0036] Please refer to Figure 1 - Figure 2 As shown, a uniform heating control device for drying tea leaves comprises a drying box body 1, a compressor 11 is installed on the upper surface of the drying box body 1, a controller 12 is installed on the front side of the compressor 11, a processing rack 13 is installed inside the drying box body 1, uniform drying mechanisms 2 are arranged on the left and right sides of the drying box body 1, and a processing oscillation mechanism 3 is arranged inside the drying box body 1;

[0037] Please refer to Figure 3 - Figure 7 As shown, the uniform drying mechanism 2 includes an air delivery pipe 21 connected to both sides of the compressor 11, and the end of the air delivery pipe 21 away from the compressor 11 is connected to the limit bin 22, the inner side wall of the limit bin 22 is fixedly connected with a sealing collar 23, the side of the sealing collar 23 close to the drying box body 1 is fixedly connected with a swirl sheet 24, the surface of the swirl sheet 24 is connected with a vortex tube 25, the inner side wall of the vortex tube 25 is fixedly connected with a splitter plate 26, the side of the limit bin 22 away from the drying box body 1 is connected with a recovery curved pipe 27, the lower end of the recovery curved pipe 27 is connected with a storage cylinder 28, and the storage cylinder 28 is connected to the storage cylinder 28. A check valve 29 is installed inside the cylinder 28 near the drying box body 1, and a nozzle 210 is connected to the end of the storage cylinder 28 away from the recovery curved pipe 27. The sealing ring 23 is composed of two parts, a disc and a cylinder, and the overall size of the disc is equal to the inner diameter of the limit bin 22, and the overall size of the cylinder is equal to the size of the swirl sheet 24. The vortex tube 25 is distributed in three sections as a whole, and the middle connection part of the vortex tube 25 is funnel-shaped as a whole. The diverter plate 26 is a three-dimensional isosceles triangle as a whole, and the surface of the vortex tube 25 corresponds to the inclined surface of the diverter plate 26. Exhaust holes are evenly penetrated and opened;

[0038] Specifically, the device transforms the flow mode of compressed air into a high-speed rotating vortex through the structural design of the swirl plate 24, so that the air molecules generate energy separation through friction and collision, thereby increasing their temperature, and cooperates with the structural position of the subsequent splitter plate 26 and the vortex tube 25 to ensure that the hot air flow can directly and efficiently act on each layer of tea raw materials on the processing rack 13. The structural characteristics of the vortex tube 25 itself also achieve uniform diffusion and vertical penetration of the hot air flow, thereby effectively avoiding the heat attenuation and uneven distribution of the hot air flow during the descending process;

[0039] Please refer to Figure 8 - Fig.10 As shown, the processing oscillation mechanism 3 includes a positioning frame 31 fixedly connected to the inside of the drying box body 1, the positioning frame 31 is rotatably connected to the processing frame 13, the surface of the positioning frame 31 is evenly and symmetrically fixedly connected with a fixed shell 32, the inner side wall of the fixed shell 32 is evenly opened with a curved groove 35, the outer wall of the processing frame 13 is evenly and fixedly connected with a double-layer sleeve 33, the outer wall of the double-layer sleeve 33 is evenly and fixedly connected with a spring 34, the fixed shell 32 is in an incomplete arc shape as a whole, the outer wall of the processing frame 13 corresponding to the position of the curved groove 35 is fixedly connected with a cylindrical protrusion, and the spring 34 is rotatably connected to the processing frame 13 through the cylindrical protrusion and the curved groove 35;

[0040] Specifically, the device enables the tea leaves to be fully turned and dispersed during the drying process. This dynamic adjustment not only increases the contact area between the tea leaves and the hot air, improves the heat transfer efficiency, but also promotes the rapid evaporation and discharge of the water inside the tea leaves, while effectively avoiding the accumulation and overheating of the tea leaves during the drying process, ensuring that the tea leaves are evenly heated and properly dried during the drying process.

[0041] The following are the complete usage steps and working principles of the above embodiment:

[0042] The use process of the device is as follows: before use, first ensure that the drying box body 1 has been correctly installed and powered on, then mix the prepared tea raw materials according to a certain amount and proportion, and put them in layers on the surface of the processing rack 13 inside the drying box body 1, and finally start the drying box body 1 to start drying the tea leaves;

[0043] The uniform drying mechanism 2 is used for uniformly drying the tea leaves inside the drying box body 1 and timely cooling the tea leaves.

[0044] like Figure 1 and Figure 2 As shown, when the device is started, the compressor 11 continuously inputs compressed air into the air pipes 21 on both sides. When the compressed air enters the limit bin 22 along the air pipes 21, as shown in FIG. Figure 4 and Figure 5As shown, since the sealing ring 23 is composed of two parts, a disc and a cylinder, and the overall size of the disc is equal to the inner diameter of the limiting bin 22, and the overall size of the cylinder is equal to the size of the swirl sheet 24, the flowing compressed air can only flow along the arc groove on the surface of the swirl sheet 24. Under the limiting effect of the swirl sheet 24, a high-speed rotating vortex will be formed in the vortex tube 25. In this process, due to the action of centrifugal force, the gas will be divided into two parts, the heavier gas molecules will be pushed to the outside of the vortex, and the lighter gas molecules will gather toward the center. The air molecules will generate energy separation due to friction and collision, resulting in a sharp drop in the temperature of the air flow in the center. The low-temperature gas in the center will move in the opposite direction through the recovery curved tube 27 into the storage tube 28, while the temperature of the outer layer of air flow will increase and the speed will decrease, and it will be pushed to the outer wall and flow out of the vortex tube 25.

[0045] like Figure 6 and Figure 7 As shown, since the splitter plate 26 is a three-dimensional isosceles triangle as a whole, and exhaust holes are evenly opened on the surface of the vortex tube 25 corresponding to the inclined surface of the splitter plate 26, when the hot air flows into the vortex tube 25 in the form of a vortex and contacts the splitter plate 26, the hot air flow will continue to flow along the inclined surface walls on both sides of the splitter plate 26, and then flow from the position of the exhaust holes on the surface of the vortex tube 25 to the inside of the drying box body 1. According to the structural position of the vortex tube 25, it is ensured that the hot air flow can directly and efficiently act on each layer of tea raw materials on the processing rack 13, achieving uniform diffusion and vertical penetration of the hot air flow, and effectively avoiding the heat attenuation and uneven distribution problems of the hot air flow during the descending process;

[0046] In addition, if Figure 4 , Figure 5 as well as Figure 6 As shown, when the low-temperature gas in the center of the vortex tube 25 mentioned above moves in the reverse direction through the recovery curved tube 27 and enters the storage tube 28, as the cold air flow continues to flow, the cold air flow will gradually accumulate in the storage tube 28. When the drying process in the drying box body 1 is completed, the staff opens the check valve 29, so that the cold air flow in the storage tube 28 can flow into the interior of the drying box body 1 through the nozzle 210. By simply operating the check valve 29, the cold air flow in the storage tube 28 can be introduced into the tea processing area to quickly cool the tea. This design of heat energy recycling not only reduces heat emissions to the external environment, but also significantly improves the overall energy utilization efficiency.

[0047] The processing vibration mechanism 3 is used for irregularly vibrating the tea raw materials, thereby coordinating with the drying process of the tea raw materials. When used specifically:

[0048] like Figure 8 and Fig. 9As shown, since the outer wall of the processing frame 13 corresponding to the curved groove 35 is fixedly connected with a cylindrical protrusion, and the spring 34 is rotationally connected to the processing frame 13 through the cylindrical protrusion and the curved groove 35, when the processing frame 13 is in a normal rotation process as a whole, when the cylindrical protrusion passes the position of the curved groove 35 on the inner side wall of the fixed shell 32, the cylindrical protrusion will continue to slide along the inner wall of the curved groove 35, and then swing up and down under the action of the shape of the curved groove 35 itself, and as shown in FIG. Fig.10 As shown, since the processing rack 13 and the double-layer sleeve 33 are movably connected by the spring 34, when the processing rack 13 is separated from the curved groove 35, the swing force of the processing rack 13 itself will act on the spring 34. At this time, the spring 34 will react on the processing rack 13 again according to its own elasticity, thereby driving the processing rack 13 to oscillate within a certain range. Through the coordinated cooperation between these structures, the tea leaves on the processing rack 13 are continuously subjected to the force of swinging and vibrating, and then the placement position is continuously adjusted in an irregular form to prevent the tea leaves from piling up and affecting the drying. This dynamic adjustment not only increases the contact area between the tea leaves and the hot air, and improves the heat transfer efficiency, but also promotes the rapid evaporation and discharge of the moisture inside the tea leaves, while effectively avoiding the accumulation and overheating of the tea leaves during the drying process, ensuring that the tea leaves are evenly heated and moderately dried during the drying process.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
