Description

Technical Field

[0001] This application relates to the field of tea production equipment, and in particular to an intelligent tea drying chamber. Background Technology

[0002] The tea preparation process usually includes a series of processes such as picking, primary processing, rolling, drying, and packaging. The primary processing process varies for different varieties of tea, but it can be roughly divided into processes such as fixation, air drying, or withering. Although these three methods all involve the primary processing of tea, they differ significantly in purpose, method, and impact on tea quality.

[0003] Among them, the initial processing of oolong tea uses the withering process, which involves spreading fresh tea leaves out in a ventilated environment so that the leaves can slowly lose moisture through natural evaporation or slight fermentation, while promoting the transformation of internal substances.

[0004] In actual production, the withering time for tea leaves is typically 1-2 hours, meaning fresh tea leaves need to remain in the withering equipment for 1-2 hours. Therefore, withering equipment is usually a single machine, where operators manually spread the tea leaves on a carrier surface before placing them in the withering equipment. However, with the development of industrial technology, to achieve automated tea production, the withering process needs to be carried out on an assembly line. To ensure that fresh tea leaves remain on the assembly line for a sufficient time, existing withering equipment assembly lines are often very long, resulting in a large amount of space being occupied in the production workshop, leading to a serious waste of space resources, which needs to be improved. Utility Model Content

[0005] Based on this, this application provides a smart tea drying chamber that can reduce the production space occupied by the overall equipment and facilitate its widespread use.

[0006] The intelligent tea drying chamber provided in this application adopts the following technical solution: A smart tea drying chamber includes a container body. The top of the container body has an inlet for tea leaves to enter. Inside the container body are multiple sets of drying conveyor lines for receiving and transporting tea leaves. Each set of drying conveyor lines is arranged at intervals along the vertical direction, and each drying conveyor line has a discharge area between itself and the side wall of the container body, through which the tea leaves can enter the next set of drying conveyor lines. Inside the container body are an environmental control system and a monitoring system for controlling the drying environment.

[0007] Optionally, the two adjacent material dropping areas of each pair of adjacent drying conveyor lines are located on both sides of the extension direction of the container body.

[0008] Optionally, the belt speed of each set of greening conveyor lines can be adjusted individually.

[0009] Optionally, the environmental control system includes ventilation ducts and multiple sets of atomizing humidification ducts. The ventilation ducts are connected to an air conditioning unit for temperature control. The number of atomizing humidification ducts is adapted to the number of the drying conveyor lines. Each set of atomizing humidification ducts is set above each set of drying conveyor lines, and all atomizing humidification ducts are connected to an atomizer.

[0010] Optionally, the monitoring system includes multiple multi-functional sensors installed inside the container body, with all multi-functional sensors evenly distributed on the inner wall of the container body; the multi-functional sensors integrate temperature and humidity detection and carbon dioxide detection functions.

[0011] Optionally, the monitoring system also includes wide-angle cameras installed on the inner wall of the modular housing.

[0012] Optionally, the intelligent tea drying chamber also includes a storage bin located on the outside of the main body of the chamber. A conveying mechanism is provided between the storage bin and the main body of the chamber to convey the tea to the inlet.

[0013] Optionally, the conveying mechanism includes a conveying line and a motor assembly for driving the conveying line to operate. One end of the conveying line is partially located in the storage bin, and the other end extends above the feed inlet. Multiple scrapers are evenly distributed on the surface of the conveying line.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up multiple sets of withering conveyor lines and arranging them at intervals along the vertical direction, the tea leaves can pass through each set of withering conveyor lines from top to bottom after entering the container body through the feed inlet. This greatly extends the movement path of the tea leaves within a limited space, ensuring that the tea leaves stay in the withering chamber for a sufficient amount of time and achieve a good withering effect.

[0015] 2. By making the belt speed of each group of withering conveyor lines individually adjustable, the conveying speed of each group of withering conveyor lines can be adjusted during the actual withering operation, so that the speed of different withering conveyor lines is different. This can change the spreading thickness of the tea leaves, so as to make all the tea leaves wither evenly and improve the withering quality of the tea leaves.

[0016] 3. By setting up an environmental control system, the ventilation ducts deliver fresh air to the interior of the container through an external air conditioning unit, which can keep the temperature inside the container within a constant and suitable range; the atomizing humidification ducts deliver humidified air to the interior of the container through an external atomizer, which can keep the humidity inside the container within a constant and suitable range.

[0017] 4. By setting up a monitoring system, the multi-functional sensors installed inside the container can simultaneously detect the temperature, humidity, and carbon dioxide content inside the container. They can also transmit the data to the central control processor to control the environmental regulation system, so as to achieve dynamic and precise adjustment of the internal environment of the container, ensuring that all parameters are always stable within the optimal range, and providing scientific guarantee for the benign transformation of the internal substances of tea.

[0018] 5. By setting up a wide-angle camera, the real-time status of tea leaves on the drying conveyor line can be continuously captured. The captured images can be displayed on the screen through the central control system, thereby realizing the full-process visual monitoring of tea drying operations.

[0019] 6. By setting up a conveying mechanism, the operator places the fresh tea leaves in the storage bin and controls the operation of the motor assembly to force the conveying line to move. The scraper on the conveying line can drive the tea leaves to move, thereby conveying the tea leaves to the feed inlet and causing them to fall through the feed inlet onto the top drying conveyor line, thus realizing automatic feeding of tea leaves.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0023] This application discloses an intelligent tea drying chamber.

[0024] Reference Figure 1A smart tea drying chamber includes a container body 1 and a storage bin 2 located outside the container body 1. The storage bin 2 is fixedly installed on the ground foundation and includes two side support plates 21 and a side end baffle 22 fixed between the two side support plates 21. The side end baffle 22 and the two side support plates 21 together form a storage space 23 for storing tea leaves, allowing workers to place freshly picked tea leaves into the storage space 23. The top of the container body 1 is provided with a feed inlet 11, which is hopper-shaped. A conveying mechanism 3 is provided between the storage bin 2 and the feed inlet 11 to transport the tea leaves to the feed inlet 11.

[0025] Specifically, the conveying mechanism 3 includes a conveying line 31 and a motor assembly for driving the conveying line 31. One end of the conveying line 31 is partially located in the storage space 23, and the other end of the conveying line 31 extends directly above the feed inlet 11. Multiple scrapers 32 are evenly distributed on the surface of the conveying line 31. In this embodiment, each scraper 32 is toothed and can scrape the tea leaves inside the storage space 23 when the conveying line 31 is moving, and gradually move the tea leaves to directly above the feed inlet 11. Finally, the tea leaves can enter the container body 1 through the feed inlet 11.

[0026] The container body 1 is equipped with multiple sets of withering conveyor lines 12, which are arranged equidistantly in a vertical direction. The feed inlet 11 is located directly above the front end of the withering conveyor line 12, so that the tea leaves can fall onto the uppermost withering conveyor line 12 after passing through the feed inlet 11. A discharge outlet 14 is opened on one inner wall of the container body 1, and the end of the lowermost withering conveyor line 12 is directly opposite the discharge outlet 14, so that the tea leaves can leave the container body 1 through the discharge outlet 14.

[0027] Simultaneously refer to Figure 2 In this embodiment, the conveying directions of every two adjacent sets of withering conveyor lines 12 are reversed. The front end of each set of withering conveyor lines 12 abuts against one inner wall of the container body 1, while the rear end of the other set of withering conveyor lines 12 maintains a distance from the other inner wall of the container body 1, thus forming a material drop area 13. The tea leaves can pass through the material drop area 13 and enter the next set of withering conveyor lines 12 as they are conveyed by the withering conveyor lines 12. Therefore, the two adjacent material drop areas 13 located on each pair of adjacent withering conveyor lines 12 can be located on both sides of the extension direction of the container body 1, thereby maximizing the movement path of the tea leaves inside the container body 1 and ensuring that the tea leaves stay in the withering chamber for a sufficient time to achieve a good withering effect.

[0028] Furthermore, in this embodiment, the belt conveyor speed of each set of withering conveyor lines 12 is individually adjustable. During the actual withering operation, by adjusting the conveyor speed of each set of withering conveyor lines 12, a speed difference can be created between two adjacent sets of withering conveyor lines 12. If the conveyor speed of the lower withering conveyor line 12 is greater than that of the upper withering conveyor line 12, when the tea leaves leave from the upper withering conveyor line 12 and fall through the dropping area 13 onto the lower withering conveyor line 12, the thickness of the spread tea leaves can gradually decrease. That is, the local stacking of tea leaves is improved, which is conducive to the uniform withering of all tea leaves and improves the withering quality of the tea leaves.

[0029] Reference Figure 3 The container body 1 is also equipped with an environmental control system 4 and a monitoring system 5. Through the environmental control system 4 and the monitoring system 5, the curing environment inside the container body 1 can be monitored and controlled in real time, realizing intelligent operation. Specifically, the environmental control system 4 includes a ventilation duct 41 and a misting humidification duct 42. The ventilation duct 41 passes through the container body 1 and is located at the top of the container body 1, and the surface of the ventilation duct 41 is provided with multiple ventilation holes. One end of the ventilation duct 41 is connected to an air conditioning unit 6. When the air conditioning unit 6 is operating, it can heat the airflow to a set temperature and send the airflow into the container body 1 to achieve temperature control and regulation inside the container body 1.

[0030] Multiple atomizing humidification pipes 42 are provided. In this embodiment, the specific number of atomizing humidification pipes 42 is equal to the number of drying conveyor lines 12. Each set of atomizing humidification pipes 42 is respectively installed above each set of drying conveyor lines 12. Each atomizing humidification pipe 42 is equipped with multiple atomizing nozzles (not shown in the figure), and each atomizing nozzle is equidistantly arranged along the extension direction of the atomizing humidification pipe 42. All atomizing humidification pipes 42 are connected to an atomizer. Based on this, by controlling the operation of the atomizer, the atomizer can generate and supply moisture to the interior of the container body 1, so as to achieve control and regulation of the humidity inside the container body 1.

[0031] Back Figure 2 The monitoring system 5 includes a multi-functional sensor 51 and a wide-angle camera 52. Multiple multi-functional sensors 51 are provided, and all multi-functional sensors 51 are evenly distributed on the inner wall of the container body 1. Specifically, all multi-functional sensors 51 are divided into multiple groups, with each group corresponding to a specific set of drying conveyor lines 12. Furthermore, each group of multi-functional sensors 51 includes multiple multi-functional sensors 51, and these sensors are equidistantly distributed along the conveying direction of the drying conveyor line 12. In this embodiment, the multi-functional sensor 51 is a three-in-one sensor integrating temperature, humidity, and carbon dioxide, capable of integrating temperature detection, humidity detection, and carbon dioxide concentration detection functions.

[0032] Based on this, this embodiment uses a multi-functional sensor 51 to continuously collect and monitor the internal conditions of the container body 1, collecting multiple key environmental parameters including temperature, humidity, and carbon dioxide concentration, and feeding these parameters back to the central control processor of the container body 1 to control the environmental regulation system 4. This enables dynamic and precise adjustment of the internal environment of the container body, ensuring that all parameters remain stable within the optimal range, and providing a scientific guarantee for the benign transformation of the internal substances of tea.

[0033] The wide-angle camera 52 is fixed to the inner wall of the container body 1 and close to the top of the container body 1. It can continuously collect images of the tea leaves on the withering conveyor line 12 in real time, so as to observe the degree of withering, color change and uniformity of withering in real time. Multiple wide-angle cameras 52 can also be arranged to achieve the purpose of collecting real-time images of all the tea leaves on the withering conveyor line 12.

[0034] The main body of the container is equipped with a display screen 7, which is electrically connected to the central control processor. The images captured by the wide-angle camera 52 can be processed by the central control processor and displayed on the display screen 7, thereby realizing the full-process visual monitoring of tea drying operations.

[0035] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
