Description

Technical Field

[0001] This utility model relates to the field of tea production technology, and in particular to a drying device for tea production. Background Technology

[0002] Drying is a crucial step in tea production. The purpose of drying tea leaves is to remove excess moisture, stop fermentation, and simultaneously fix the shape and enhance aroma. Proper drying helps maintain good quality, extends shelf life, and plays a decisive role in shaping the unique flavor and taste of tea.

[0003] Currently, in the tea production and drying process, common drying equipment has a simple internal structure and uneven distribution of hot air, resulting in inconsistent drying levels of tea. Some drying devices rely on only a single heat source, making it difficult to achieve all-round and uniform drying of tea. Moreover, during the drying process, tea is often placed statically or simply turned over, resulting in insufficient contact with hot air, which slows down the drying speed and affects the quality of the tea. Therefore, we propose a drying device for tea production to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and to propose a drying device for tea production.

Multiple drying holes are opened on the outer side wall of the feeding plates. A cover box communicating with the multiple drying holes is fixedly installed at the bottom of the feeding plates. An air inlet pipe communicating with the cover box is fixedly installed on the inner side wall of the drying chamber. A drying fan is fixedly installed on the outer side wall of the drying chamber. The air outlet of the drying fan and the multiple air inlet pipes are fixedly connected through the same air distribution pipe.

[0006] Preferably, the top of the drying box has a feed inlet and an air outlet, the top of the drying box has a feed funnel connected to the feed inlet, and the bottom of the drying box has a discharge outlet.

[0007] Preferably, the distance between any two adjacent drying holes is the same.

[0008] Preferably, two adjacent feed plates with opposite orientations and spaced apart are arranged in parallel.

[0009] Preferably, the air distribution duct consists of a main duct and multiple branch ducts, wherein the air inlet of the main duct and the air outlet of the drying fan are connected, and the main duct and the multiple branch ducts are connected.

[0010] Preferably, the inner wall of the drying oven is provided with multiple fixing holes, and the air inlet pipe on the same side is fixedly connected to the inner wall of the fixing hole.

[0011] The beneficial effects of this utility model are as follows: Through the interaction of the drying chamber, drying mechanism, feeding funnel, discharge port, and air outlet, the inclined and cleverly arranged feeding plate in the drying mechanism increases the contact time and area between the tea leaves and hot air. Combined with the evenly distributed drying holes, it ensures that the hot air acts on the tea leaves from all directions without dead angles, achieving efficient and uniform drying.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5A drying device for tea production includes a drying chamber 1, which is equipped with a drying mechanism. The drying mechanism includes multiple inclined feeding plates 2 fixedly installed on the inner wall of the drying chamber 1. Multiple drying holes 3 are opened on the outer wall of the feeding plates 2. A cover box 4 communicating with the multiple drying holes 3 is fixedly installed at the bottom of the feeding plates 2. An air inlet pipe 5 communicating with the cover box 4 is fixedly installed on the inner wall of the drying chamber 1. A drying fan 6 is fixedly installed on the outer wall of the drying chamber 1. The air outlet of the drying fan 6 and the multiple air inlet pipes 5 are fixedly connected through the same air distribution pipe 7.

[0016] To further explain, the multiple inclined feeding plates 2 increase the contact area and contact time between the tea leaves and the hot air. The hot air is blown out from the drying holes 3 and acts directly on the tea leaves to achieve efficient drying and ensure the drying effect. Through the connection design of the air inlet pipe 5, the cover box 4 and the drying holes 3, and the air distribution pipe 7 connecting the air outlet of the drying fan 6 to multiple air inlet pipes 5, the hot air can be blown out evenly from each drying hole 3, ensuring that the tea leaves in each place can be dried evenly and improving the consistency of drying.

[0017] like Figure 1 As shown, the top of the drying box 1 is provided with a feed inlet 8 and an air outlet 9. A feed funnel 10 connected to the feed inlet 8 is fixedly installed on the top of the drying box 1, and an outlet 11 is provided at the bottom of the drying box 1.

[0018] To further explain, the feed funnel 10 is connected to the feed inlet 8, which facilitates the pouring of tea leaves to be dried into the drying chamber 1, reducing tea leaf spillage and improving feeding efficiency. The air outlet 9 ensures that hot air can be smoothly discharged during the drying process, maintaining air circulation inside the drying chamber 1, which is beneficial for continuous drying operations. The discharge outlet 11 facilitates the discharge of dried tea leaves, making the entire drying process smooth and continuous.

[0019] like Figure 2 As shown, the distance between any two adjacent drying holes 3 is the same.

[0020] To further explain, this design ensures that the hot air is evenly distributed at all locations when it is blown out from the drying hole 3, avoiding uneven drying of the tea leaves due to inconsistent spacing of the drying holes 3, thereby improving the stability of the tea drying quality.

[0021] like Figure 1 As shown, two adjacent feed plates 2 are arranged in parallel with opposite orientations and spaced apart.

[0022] To further explain, this design causes the tea leaves to fall in an "S" shaped path during the feeding process. This setting prolongs the residence time of the tea leaves in the drying chamber 1 and increases the contact time between the tea leaves and the hot air, which is beneficial to improving drying efficiency and drying effect.

[0023] like Figure 1 and Figure 5 As shown, the air distribution duct 7 consists of a main duct and multiple branch ducts. The air inlet of the main duct and the air outlet of the drying fan 6 are connected. The main duct and the multiple branch ducts are also connected.

[0024] To further explain, this design enables the hot air generated by the drying fan 6 to be accurately distributed to each air inlet pipe 5, and then delivered to the drying hole 3 of each material discharge plate 2, ensuring the stability and accuracy of the hot air supply and providing a guarantee for efficient and uniform drying.

[0025] like Figure 1 As shown, multiple fixing holes are provided on the inner wall of the drying oven 1, and the air inlet pipe 5 on the same side is fixedly connected to the inner wall of the fixing hole.

[0026] To further explain, this design ensures the secure installation of the air inlet pipe 5, preventing it from loosening during the drying process due to vibration or other reasons, thus affecting the delivery of hot air and ensuring the stable operation of the drying device.

[0027] The functional principle of this utility model can be explained through the following operation methods: Feeding: The tea leaves to be dried are poured into the drying chamber 1 through the feeding funnel 10, which is connected to the feeding port 8 at the top of the drying chamber 1. Due to the design of the feeding funnel 10, the tea leaves can be effectively reduced from spilling, making the feeding operation convenient and quick.

[0028] Start the drying fan 6: Turn on the drying fan 6 installed on the outer wall of the drying chamber 1. The drying fan 6 generates hot air, which enters the air inlet pipe 5 through the air distribution pipe 7. The air distribution pipe 7 consists of a main pipe and multiple branch pipes. The air inlet end of the main pipe is connected to the air outlet of the drying fan 6, which can evenly distribute the hot air to each branch pipe, and then deliver it to the cover box 4 through the air inlet pipe 5.

[0029] Drying process: Hot air is blown out from the covering box 4 through the drying holes 3 and acts on the tea leaves on the feeding plate 2. Since the multiple feeding plates 2 are set at an angle, and the orientation of two adjacent feeding plates 2 is opposite and the two feeding plates 2 with intervals are set in parallel, the tea leaves will fall along an "S" shaped path. During this process, hot air is continuously blown out from the drying holes 3 to fully dry the tea leaves. At the same time, the distance between adjacent drying holes 3 is the same to ensure that the hot air acts evenly on the tea leaves and ensures the consistency of the drying effect.

[0030] Discharging the dried tea leaves: After drying is completed, the dried tea leaves are discharged from the discharge port 11 at the bottom of the drying chamber 1. At the same time, the air outlet 9 at the top of the drying chamber 1 ensures that hot air is discharged smoothly during the drying process, maintains air circulation inside the chamber, and is conducive to the continuous operation of the entire drying process.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
