Description

Technical Field

[0001] This utility model relates to the technical field of tea withering machines, specifically an energy-saving tea withering machine. Background Technology

[0002] Most existing tea withering machines use a method of loading the tea leaves as a whole into the equipment for processing. This traditional method often results in the tea leaves not being able to make sufficient and even contact with the hot air, irradiation lamps, and other equipment, thus affecting the withering effect and the quality of the tea. Because the tea leaves are piled loosely or unevenly in the equipment, some leaves may not receive enough heat or irradiation, leading to incomplete withering or uneven processing, which affects the final quality of the tea. In addition, since the withering process of tea leaves requires the removal of moisture, the heat in traditional equipment is often not effectively distributed or recycled. The hot air entering the equipment is directly discharged after drying the tea leaves, resulting in a large waste of heat energy. This inefficient use of heat not only makes the equipment's energy consumption high, but also makes the tea processing process lack energy-saving effects.

[0003] Therefore, there is still considerable room for improvement in the withering efficiency, uniformity of tea quality, and recycling of heat in existing withering machines. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide an energy-saving tea withering machine, which improves the withering quality of tea, achieves significant energy-saving effect, and has strong market competitiveness and application prospects.

[0005] The technical solution adopted by this utility model to achieve the above objectives is: an energy-saving tea withering machine, including a processing box, a hanging bracket, and a tea storage tray. The hanging bracket is rotatably installed in the processing box and rotates around a horizontal axis. The tea storage tray is evenly hung on the hanging bracket and is used to support the tea leaves to be withered. Ventilation holes are evenly opened at the bottom of the tea storage tray.

[0006] It also includes an irradiation assembly, a wind distribution plate, and a wind collection hood. The irradiation assembly is fixedly installed in the processing box and arranged at the axial position of the hanging bracket. The wind distribution plate is fixedly installed at the bottom of the processing box, and the wind collection hood is fixedly installed at the top of the processing box.

[0007] It also includes a heat exchanger, a blower, and an air heater. The blower is connected to the air distribution plate through an air supply pipe, and the air supply pipe is connected to the refrigerant interface of the heat exchanger. The air heater is mounted on the air supply pipe and arranged on the downstream side of the heat exchanger. The air collector is connected to an exhaust pipe, and the exhaust pipe is connected to the heat medium interface of the heat exchanger.

[0008] Based on the above technical solutions, in order to ensure the sealing effect of the processing box and facilitate the handling of the tea storage tray, and to ensure the stable installation of the heat exchanger, blower, and air heater, the following technical solutions are provided.

[0009] The processing box is provided with a loading and unloading port, and a sealing cover is hinged to the loading and unloading port to maintain a nested seal with the loading and unloading port. An installation box is fixedly connected to the bottom of the processing box, and the heat exchanger, blower and air heater are all fixedly installed in the installation box.

[0010] Based on the above technical solutions, in order to ensure that the blower can introduce clean air from the outside and effectively output the exhaust gas through the heat exchanger, the following technical solutions are provided.

[0011] The mounting box has an air inlet and an air outlet. The blower is connected to the air inlet. A dust cover is installed at the air inlet. An exhaust hood is connected to the end of the exhaust pipe. The exhaust hood is located on the downstream side of the heat exchanger and is connected to the exhaust outlet.

[0012] Based on the above technical solutions, in order to ensure that the hanging bracket can be stably installed in the treatment box by relative rotation, and to ensure that the irradiation component can be stably installed at the axial position of the hanging bracket, the following technical solutions are provided.

[0013] The hanging bracket includes two sets of coaxially arranged rotating ring seats and hanging rods arranged in a ring array and fixed between the two sets of rotating ring seats. The processing box has assembly grooves at both ends, and assembly covers arranged around the assembly grooves are fixed at both ends of the processing box. The rotating ring seats are rotatably installed in the assembly grooves, and the hanging rods are arranged in the processing box.

[0014] The irradiation assembly includes two sets of coaxially arranged mounting disks and irradiation lamps arranged in a ring array and connected between the two sets of mounting disks. The mounting disks are fixedly installed in the assembly cover, and the irradiation lamps are arranged inside the rotating ring seat.

[0015] Based on the above technical solutions, the following technical solutions are provided to ensure that the hanging bracket can operate stably in a relative rotation manner.

[0016] The rotating ring seat is powered by a drive motor, which is fixedly installed on the outer wall of the processing box and arranged inside the assembly cover. A drive bevel gear is fixedly connected to the output shaft of the drive motor, and a transmission bevel gear that meshes with the drive bevel gear is fixedly connected to one of the rotating ring seats.

[0017] Based on the above technical solutions, in order to ensure that the tea storage tray can be stably hung on the hanging rod and move with the hanging bracket, the following technical solutions are provided.

[0018] A connecting bracket is fixed to the tea storage tray, and a hook is fitted at the top of the connecting bracket. An annular positioning groove is provided on the hanging rod, and the hook is hung in the annular positioning groove.

[0019] The beneficial effects of this utility model are:

[0020] 1. Uniform Tea Processing: A hanging rack is used to evenly suspend the tea storage trays, and rotation ensures the tea leaves circulate freely. This even distribution of tea leaves on the trays guarantees sufficient interaction with the hot air and irradiation lamps, thus improving the uniformity and effectiveness of withering and avoiding uneven withering and quality variations caused by uneven tea stacking in traditional methods.

[0021] 2.* Improved Withering Efficiency: By combining the irradiation unit and the air distribution plate, the surface of the tea leaves can be evenly irradiated and heated. Simultaneously, hot air flows effectively through the air distribution plate to the tea storage tray, and through the ventilation holes, it removes moisture and ventilates the tea leaves, promoting rapid evaporation of moisture and withering. This design effectively improves withering efficiency and shortens processing time.

[0022] 3. Significant Energy Saving: Heat can be recycled. Through the combined use of a heat exchanger and an air heater, the hot air removed from the tea leaves is collected by a hood and transported to the heat exchanger. The heat exchanger preheats the incoming air by reusing the heat medium. The blower draws in outside air, preheats it, and then delivers it to the processing chamber, thus achieving efficient heat recovery and reuse, greatly reducing energy consumption and demonstrating excellent energy-saving effects.

[0023] In summary, the tea withering machine proposed in this solution not only improves the withering quality of tea by optimizing hot air flow, increasing heat recovery efficiency, and processing tea evenly, but also achieves significant energy-saving effects, demonstrating strong market competitiveness and application prospects.

[0032] 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.

[0033] Please see Figure 1-7 An energy-saving tea withering machine includes a processing box 1, a hanging bracket 2, and a tea storage tray 3. The hanging bracket 2 is rotatably installed in the processing box 1 and rotates around a horizontal axis. The tea storage tray 3 is evenly hung on the hanging bracket 2 and is used to support the tea leaves to be withered. Ventilation holes 31 are evenly opened at the bottom of the tea storage tray 3.

[0034] It also includes an irradiation assembly 4, a wind distribution plate 5, and a wind collection hood 6. The irradiation assembly 4 is fixedly installed in the treatment box 1 and arranged at the axis position of the hanging bracket 2. The wind distribution plate 5 is fixedly installed at the bottom of the treatment box 1, and the wind collection hood 6 is fixedly installed at the top of the treatment box 1.

[0035] It also includes a heat exchanger 7, a blower 8, and an air heater 9. The blower 8 is connected to the air distribution plate 5 via an air supply pipe 51. The air supply pipe 51 is connected to the refrigerant interface of the heat exchanger 7. The air heater 9 is mounted on the air supply pipe 51 and arranged on the downstream side of the heat exchanger 7. The air collector hood 6 is connected to an exhaust pipe 61, which is connected to the heat medium interface of the heat exchanger 7.

[0036] When withering tea leaves using this tea withering machine, the tea leaves are evenly spread on each tea storage tray 3 and hung on the hanging bracket 2. As the hanging bracket 2 operates stably, it drives the tea storage trays 3 to circulate. Then, with the help of the irradiation component 4 and the air distribution plate 5, the hot air transported by the air distribution component 4 removes some moisture from the fresh tea leaves, making the leaves soft and tender, thus improving the quality of the tea.

[0037] The irradiation component 4 can irradiate and dehydrate the fresh tea leaves on the tea storage tray 3. The air distribution plate 5 can blow the hot air upwards onto the tea storage tray 3, and then ventilate and dehydrate the tea leaves in the tea storage tray 3 through the ventilation holes 31. The hot air after the tea leaves are treated is collected by the air collector 6, and then transported to the heat medium passage of the heat exchanger 7 through the exhaust pipe 61. The blower 8 draws in the outside air and transports it to the refrigerant passage of the heat exchanger 7 along the air supply pipe 51. The exhaust air transported to the heat exchanger 7 by the exhaust pipe 61 preheats the air transported by the air supply pipe 51, realizing the recycling of heat. The air output from the heat exchanger 7 and after being preheated is transported to the air heater 9. After the air is heated to a certain stable temperature, it is transported to the processing box 1 by the air distribution plate 5, realizing the energy-saving effect of tea leaf withering treatment.

[0038] To ensure the sealing effect of the processing box 1 and facilitate the removal of the tea storage tray 3, as well as to ensure the stable installation of the heat exchanger 7, blower 8, and air heater 9, the following technical solutions are provided.

[0039] The processing box 1 is provided with a loading and unloading port 11. A sealing cover 12 is hinged to the loading and unloading port 11 to maintain a nested seal with the loading and unloading port 11. An installation box 13 is fixedly connected to the bottom of the processing box 1. The heat exchanger 7, the blower 8, and the air heater 9 are all fixedly installed in the installation box 13.

[0040] The loading and unloading port 11 allows the tea storage tray 3 containing tea leaves to easily enter and exit the processing box 1, and makes it easy to hang the tea storage tray 3 on the hanging bracket 2 or remove it from the hanging bracket 2. When the sealing cover 12 is closed, it can ensure the sealing effect of the processing box 1, prevent the hot air from leaking out from the loading and unloading port 11, affect the withering effect, and achieve energy saving.

[0041] To ensure that the blower 8 can introduce clean air from outside and effectively output the exhaust gas flow through the heat exchanger 7, the following technical solution is provided.

An exhaust hood 62 is connected to the end of the exhaust pipe 61. The exhaust hood 62 is located on the downstream side of the heat exchanger 7 and is connected to the exhaust outlet 132.

[0043] The air inlet is designed to ensure that outside air enters the blower 8 through the mounting box 13, and the dust cover 133 intercepts the dust carried in the air, thus ensuring the cleanliness of the air entering the processing box 1. The exhaust outlet is designed to ensure that the exhaust air collected by the air collection hood 6 is discharged to the outside of the mounting box 13 after heat exchange through the heat exchanger 7.

The rotating ring seats 21 are rotatably installed in the assembly grooves 14, and the hanging rods 22 are arranged in the processing box 1.

[0046] The irradiation assembly 4 includes two sets of coaxially arranged mounting disks 41 and irradiation lamps 42 arranged in a ring array and connected between the two sets of mounting disks 41. The mounting disks 41 are fixedly installed in the assembly cover 15, and the irradiation lamps 42 are arranged inside the rotating ring seat 21.

[0047] The hanging bracket 2, through the matching combination of the rotating ring seat 21 and the assembly groove 14, can ensure stable installation in the processing box 1 in a relative rotation manner, thereby driving the hanging rod 22 on it to ensure synchronous rotation, and the tea storage tray 3 can be stably hung on the hanging rod 22.

[0048] The assembly cover 15 can seal the assembly groove 14 to prevent internal hot air from leaking out from here, and at the same time, it can fix the mounting plate 41 in the irradiation assembly 4 on it, so as to achieve stable installation of the irradiation lamp tube 42 at the axis position of the hanging bracket 2.
