Description

Technical Field

[0001] This utility model relates to the field of tea production technology, specifically to a device for withering wolfberry leaf black tea. Background Technology

[0002] Made from Ningxia wolfberry buds and tender leaves using a unique process, this tea perfectly preserves the effective components and benefits of wolfberry leaves. To further enhance the quality, the processing typically involves washing the fresh leaves and stir-frying them to improve their aroma. The resulting wolfberry leaf tea has a delicate and mellow taste, is beneficial for health, and contains vitamins A, C, B1, B2, and various amino acids, making it an excellent choice for improving eyesight.

[0003] The withering trough is a piece of equipment used in black tea processing. It has advantages such as large leaf spreading capacity, uniform withering, and no weather influence. It can significantly improve the level of mechanization in processing, save labor, and improve the quality of black tea. The working principle of the withering trough is that hot air is sent into the trough by a fan, passing through the spread fresh leaves. The leaves are heated and the moisture evaporates, causing them to gradually soften. In order to prevent the temperature from being too high and destroying the enzyme activity, thus affecting the quality of the finished tea, the withering trough is equipped with a cold air damper to regulate and limit the temperature. However, because the withering trough is rectangular, the air pressure drops and the air flow is significantly insufficient when the air reaches the end, resulting in poor withering effect at the end. Therefore, the existing technology has been improved to give it a pressure balancing function and solve the problem of uneven airflow distribution. Utility Model Content

[0004] The purpose of this invention is to provide a device for withering wolfberry leaves for black tea, so as to solve the problems mentioned in the background art.

Vertically distributed wave baffles are arranged inside the tank. The wave baffles are arranged at equal intervals, and adjacent wave baffles are installed in opposite directions.

[0007] As a further embodiment of this utility model: the wave baffles arranged in two opposite directions form a narrow flow zone and a wide flow zone, with the width of the narrow flow zone being consistent and the width of the wide flow zone being consistent.

[0008] As a further improvement of this utility model: fluid inlets and fluid outlets are respectively arranged at the bottom and top of two adjacent wave baffles, and the widths of the fluid inlets and fluid outlets are the same.

[0009] As a further embodiment of this utility model: the narrow flow region of the wave deflector is the wide flow region of the adjacent wave deflector, and the wide flow region of the wave deflector is the narrow flow region of the adjacent wave deflector.

[0010] As a further improvement of this utility model: the tank body is provided with a sandwich plate and a sieve plate located above the wave baffle plate, and a rectifier cavity is provided between the sandwich plate and the sieve plate. Both the sandwich plate and the sieve plate are breathable mesh, and the airflow enters the rectifier cavity for secondary rectification and is blown out from the sieve plate.

[0011] As a further improvement of this utility model: a motor, fan blades and a grille are installed inside the air box, and the output end of the motor is connected to the fan blades to drive the fan blades to rotate and push the airflow.

[0012] As a further improvement of this utility model, a heater is also provided inside the air box, and the heating temperature of the heater is controlled by a control terminal.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This equipment for withering wolfberry leaf black tea uses a wave-shaped baffle plate to limit the flow, creating air pressure at the bottom and balancing the airflow at the front and rear ends of the tank. The airflow enters the rectifier chamber for a second balancing before being blown out, ensuring uniform air pressure and consistent withering effect at both ends of the equipment.

[0020] Please see Figures 1-4In this embodiment of the utility model, a device for withering wolfberry leaf black tea includes a tank 1, a bellows 2, and a control terminal 3. The tank 1 and the bellows 2 are interconnected. Vertically distributed wave baffles 9 are arranged inside the tank 1. The wave baffles 9 are arranged at equal intervals, and adjacent wave baffles 9 are installed in opposite directions. The function of the wave baffles 9 is to reduce the outflow of air and to create a certain air pressure in the space at the bottom of the wave baffles 9. The air pressure flows to the top through the gap between adjacent wave baffles 9, so that the outflowing air pressure is the same, thereby achieving uniform airflow output and consistent withering effect.

[0021] In a preferred embodiment, two adjacent, oppositely arranged corrugated baffles 9 form a narrow flow zone 13 and a wide flow zone 12. The width of the narrow flow zone 13 is consistent, and the width of the wide flow zone 12 is consistent. The wide flow zone 12 restricts the space for airflow, so that the airflow forms a certain air pressure in the space at the bottom of the corrugated baffles 9, thereby balancing the air pressure in the bottom space and avoiding the problem of inconsistent withering effect due to insufficient airflow at the end.

[0022] In a preferred embodiment, fluid inlet 14 and fluid outlet 15 are respectively arranged at the bottom and top of two adjacent wave baffles 9. The width of fluid inlet 14 and fluid outlet 15 is the same, which is also to maintain the spatial consistency of the output airflow and balance the output airflow.

[0023] In a preferred embodiment, the narrow flow region 13 of the wave deflector 9 is the wide flow region 12 of the adjacent wave deflector 9, and the wide flow region 12 of the wave deflector 9 is the narrow flow region 13 of the adjacent wave deflector 9. The wave deflector 9 forms the narrow flow region 13 and the wide flow region 12 by bending. The wave-shaped design of the wave deflector 9 can meet the requirements of the narrow flow region 13 and the wide flow region 12, reducing the modification cost.

[0024] In a preferred embodiment, the tank 1 is provided with a sandwich plate 10 and a sieve plate 11 located above the corrugated baffle 9. A flow-rectifying cavity is provided between the sandwich plate 10 and the sieve plate 11. Both the sandwich plate 10 and the sieve plate 11 are breathable mesh. The airflow enters the flow-rectifying cavity and is rectified twice before being blown out from the sieve plate 11. Because of the flow restriction caused by the corrugated baffle 9, there is air pressure at the bottom. Therefore, the airflow output from the corrugated baffle 9 is bundled and has a high speed. In order to prevent the airflow from blowing up the tender leaves, the sandwich plate 10 is required to further cut and block the airflow and integrate the airflow.

[0025] In a preferred embodiment, a motor 5, a fan blade 6, and a grille 4 are installed inside the air box 2. The output end of the motor 5 is connected to the fan blade 6, which drives the fan blade 6 to rotate and push the airflow. A heater 7 is also provided inside the air box 2. The heating temperature of the heater 7 is controlled by the control terminal 3. The heater 7 generates heat through an electric heating wire and uses a reflector to convert the heat energy into infrared radiation for heat transfer, thereby achieving the effect of heating the airflow.

[0026] It should be noted that all the above embodiments belong to the same utility model concept, and the descriptions of each embodiment have different focuses. Where the description in a particular embodiment is not detailed, please refer to the description in other embodiments.

[0027] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
