Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying device for tea processing. Background Technology
[0002] In the tea processing industry, drying is a crucial step affecting tea quality. Existing tea drying methods are diverse, with some traditional drying equipment employing a static drying mode. During the drying process, the tea leaves remain relatively still, leading to uneven heating and potentially causing localized over- or under-drying, which in turn affects the tea's color, aroma, and taste.
[0003] Some drying devices have introduced a turning mechanism, but the structure is complex and the operation is cumbersome. During the turning process, the intervention of the turning mechanism can easily damage the tea leaves. At the same time, some drying equipment based on this often cannot achieve the classification and drying of different types or sizes of tea leaves. If multiple types of tea leaves are mixed and dried, it is difficult to control the drying time of each type of tea leaves, which cannot meet the diverse production needs. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a drying device for tea processing, which has the advantages of improving the uniformity of tea drying, enabling categorized drying, and being easy to operate, thus solving some of the problems mentioned in the background technology.
[0005] This utility model provides the following technical solution: a drying device for tea processing, including a drying box and a processing table. Inside the drying box, two sets of symmetrical semi-cylinders are fixedly installed in the middle. A drive shaft is installed in the middle of the interior of each semi-cylinder. A conical cylinder is fixedly sleeved on the outside of the drive shaft. Evenly distributed partitions are fixedly installed on the conical cylinder. Ventilation plates are fixedly installed at both ends of the conical cylinder between the semi-cylinders. An annular dehumidification disc is provided in the middle of the left end of the drying box. A sealing plate is rotatably installed at the lower end of each semi-cylinder. The edge of the partition is in contact with the inner wall of the semi-cylinder, ventilation plate, and sealing plate. A discharge port is provided at the lower end of the sealing plate between the semi-cylinders. An electric push rod is fixedly installed in the middle of the left and right inner walls of the discharge port. A clamping plate is fixedly connected to the upper end of each electric push rod, and the clamping plate presses against the connection between the two sets of sealing plates.
[0006] Furthermore, a hot air blower is installed on the upper part of the processing table near the middle of the right side. The drying box is fixedly installed on the upper left side of the processing table. An air supply duct is fixedly installed at the right end opening of the drying box. The right end of the air supply duct is connected to the air outlet of the hot air blower. The hot air blown out by the hot air blower exchanges heat with the tea leaves to achieve the drying effect. The air supply duct can prevent heat loss.
[0007] Furthermore, the left end of the drive shaft passes through and is rotatably connected to the middle of the left end of the drying box, the right end of the drive shaft is fixedly sleeved with a fixing frame, the lower end of the fixing frame is fixedly connected to the inner bottom of the drying box, and the left end of the drive shaft is fixedly sleeved with a pulley, ensuring the rationality of the structure.
[0008] Furthermore, a geared motor is fixedly installed on the upper end of the processing table near the left side. A main pulley is fixedly sleeved on the right output end of the geared motor. A transmission belt is provided between the main pulley and the driven pulley. The main pulley is connected to the driven pulley through the transmission belt to realize the transmission between the structures.
[0009] Furthermore, a cover plate is slidably installed at the middle of the upper end of the drying box, and a leak-proof funnel is fixedly installed at the middle of the inner top wall of the drying box. The lower end of the leak-proof funnel is fixedly connected to two sets of semi-cylinders to prevent side leakage when tea leaves are poured in.
[0010] The advantages of this utility model are as follows:
[0011] 1. Hot air is blown out by a hot air blower and enters the semi-cylinder through the air supply duct and ventilation plate to dry the tea leaves. At the same time, the geared motor drives the conical cylinder to rotate, causing the partition and the tea leaves inside to rotate. When the tea leaves rotate to the upper and lower sides, they are evenly turned over due to gravity. The hot air also causes some tea leaves to move to the left, and the rotation of the conical cylinder guides the tea leaves to gather to the right. This process is repeated, which greatly improves the uniformity of tea drying, effectively avoids local high temperature, shortens the distance between the tea leaves and the hot air, improves the utilization rate of hot air, and thus improves the drying efficiency.
[0012] 2. The partition divides the space into multiple drying compartments. Adjacent compartments are separated by a middle partition and do not affect each other. Users can put tea leaves of different sizes or even different types and qualities into the drying compartment together. When taking them out, simply rotate the corresponding tea compartment to the bottom, open the electric push rod to release the limit on the sealing plate and open the feeding port. This allows for targeted control of the drying time of various types of tea without interrupting the drying process of other teas, making it flexible and versatile. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-3A drying device for tea processing includes a drying chamber 1 and a processing table 20. Inside the drying chamber 1, two sets of symmetrical semi-cylinders 2 are fixedly installed in the middle. A drive shaft 3 is installed in the middle of the interior of each semi-cylinder 2. A conical cylinder 4 is fixedly sleeved on the outside of the drive shaft 3. Evenly distributed partitions 5 are fixedly installed on the conical cylinder 4. Ventilation plates 6 are fixedly installed at both ends of the conical cylinder 4 between the semi-cylinders 2. An annular dehumidification disc 13 is provided in the middle of the left end of the drying chamber 1. Sealing plates 17 are rotatably installed at the lower ends of each semi-cylinder 2. The edges of the partitions 5 are connected to the semi-cylinders... The inner walls of cylinder 2, ventilation plate 6, and sealing plate 17 are fitted together. A discharge port is provided at the lower end of sealing plate 17 between the semi-cylinders 2. Electric push rods 19 are fixedly installed at the middle of the left and right inner walls of each discharge port. A clamping plate 18 is fixedly connected to the upper end of each electric push rod 19, pressing against the connection between the two sets of sealing plates 17. A cover plate 15 is slidably installed at the middle of the upper end of the drying chamber 1. A leak-proof funnel 16 is fixedly installed at the middle of the inner top wall of the drying chamber 1. The lower end of the leak-proof funnel 16 is fixedly connected to the two sets of semi-cylinders 2. The tea leaves are rotated to the upper side and... During the drying process on the lower side, gravity causes the tea leaves to tumble evenly, improving the uniformity of drying and effectively preventing localized high temperatures. Furthermore, the hot air blows some of the falling tea leaves to the left, while the conical cylinder 4 guides the tea leaves to gather on the right during rotation. This continuous cycle further improves the uniformity of drying, increasing efficiency and shortening the distance between the tea leaves and the hot air, thus improving the utilization rate of the hot air blown by the hot air blower 7. Moreover, the partition 5 can further divide the drying space into multiple groups. The two adjacent groups are separated by a partition 5 in the middle, so they do not affect each other. Therefore, users can put tea leaves of different sizes or even different tea varieties and qualities into the drying process together. When taking them out, simply rotate the same tea compartment to the bottom, and then open the electric push rod 19 to make it lower the clamping plate 18 to release the limiting clamping effect on the sealing plate 17. The sealing plate 17 will then flip down to open the feeding port, and the tea leaves can be received using a tool. At the same time, the drying time of the tea leaves can be controlled in a targeted manner without interrupting the drying process of other tea leaves, making it more flexible and versatile.
[0019] Please see Figures 1-3A hot air blower 7 is installed on the upper part of the processing table 20 near the middle of the right side. The drying box 1 is fixedly installed on the upper left side of the processing table 20. An air supply duct 8 is fixedly installed at the right end opening of the drying box 1. The right end of the air supply duct 8 is connected to the air outlet of the hot air blower 7. The left end of the drive shaft 3 passes through and is rotatably connected to the middle of the left end of the drying box 1. A fixing bracket 14 is fixedly sleeved on the right end of the drive shaft 3. The lower end of the fixing bracket 14 is fixedly connected to the inner bottom of the drying box 1. A driven pulley 9 is fixedly sleeved on the left end of the drive shaft 3. A geared motor 10 is fixedly installed on the upper part of the processing table 20 near the left side. A main pulley 11 is fixedly sleeved on the right output end of the geared motor 10. A drive belt 12 is provided between the main pulley 11 and the driven pulley 9. The main pulley 11 is connected to the driven pulley 9 via the transmission belt 12. The drying chamber 1 is opened by the sliding cover 15 and the tea leaves are poured in. Under the guidance of the anti-leakage funnel 16, the tea leaves fall between the two sets of partitions 5 on the conical cylinder 4. During drying, hot air is blown out by the hot air blower 7 and enters the interior of the semi-cylinder 2 through the ventilation plate 6 under the protection of the air supply duct 8, thereby drying the tea leaves on the conical cylinder 4. At the same time, the output end of the reduction motor 10 is turned on to drive the main pulley 11 to rotate. The rotation of the main pulley 11 drives the transmission belt 12 to rotate the driven pulley 9. The rotation of the driven pulley 9 drives the transmission shaft 3 to rotate the conical cylinder 4. Thus, the conical cylinder 4 drives the partitions 5 and the tea leaves inside to rotate.
[0020] Working Principle: During operation, the drying chamber 1 is opened via the sliding cover 15, and tea leaves are poured in. Guided by the anti-leakage hopper 16, the tea leaves fall between the two sets of partitions 5 on the conical cylinder 4. During drying, hot air is blown out by the hot air blower 7 and, under the protection of the air supply duct 8, enters the interior of the semi-cylinder 2 through the ventilation plate 6, thus drying the tea leaves on the conical cylinder 4. Simultaneously, the reduction motor 10 is turned on, causing its output end to drive the main pulley 11 to rotate. The rotation of the main pulley 11 drives the transmission belt 12, which in turn drives the driven pulley 9. The rotation of the driven pulley 9 drives the transmission shaft 3, causing the conical cylinder 4 to rotate. This, in turn, causes the partitions 5 and the tea leaves inside to rotate. As the tea leaves rotate to the upper and lower sides, they are evenly turned due to gravity, improving the uniformity of drying and effectively preventing localized high temperatures. Furthermore, the hot air blows some of the falling tea leaves away. The cone-shaped cylinder 4, when rotating, guides the tea leaves to gather on the right, continuously improving the uniformity of the tea leaves during drying and increasing drying efficiency. It also shortens the distance between the tea leaves and the hot air, thus increasing the utilization rate of the hot air blown by the hot air blower 7, making it more efficient. Furthermore, the partition 5 can divide the drying space into multiple groups, with adjacent groups separated by the middle partition 5 so they do not interfere with each other. Therefore, users can put tea leaves of different sizes or even different tea varieties and qualities together for drying. When removing the tea leaves, simply rotate the same tea compartment to the bottom, and then open the electric push rod 19 to lower the clamping plate 18, releasing the limiting clamping effect on the sealing plate 17. The sealing plate 17 will then flip downwards to open the feeding port, allowing the tea leaves to be received using a tool. Simultaneously, the drying time of the tea leaves can be controlled specifically without interrupting the drying of other tea leaves, making it more flexible and versatile.
