Description

Technical Field

[0001] This application relates to the field of tea processing technology, specifically to a tea drying oven. Background Technology

[0002] The main processing steps in tea production generally include withering, fixation, rolling, shaping, and drying. Drying is an important step in tea production, primarily aimed at removing moisture from the tea leaves while also shaping and resisting oxidation.

[0003] Existing drying equipment still has some problems, such as: low thermal efficiency: when the tea leaves pile up during static drying, the hot air is difficult to penetrate evenly, resulting in incomplete drying or local over-drying; Debris contamination: Dust and particulate matter that fall off the surface of tea leaves cannot be effectively separated and will mix into the finished product, reducing its quality; The process is cumbersome: the tea leaves need to be manually turned over during the drying process to prevent them from sticking together, which is inefficient.

[0004] Therefore, there is an urgent need for a highly efficient and integrated drying device to solve the above problems. Utility Model Content

[0005] Therefore, this application provides a tea drying oven to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this application provides the following technical solution: A tea drying oven, comprising: The insulation shell has a dust collection mechanism installed on its upper side. A sealing mechanism is bolted to the upper side of the dust collection mechanism. The dust collection mechanism and the sealing mechanism seal the upper side of the insulation shell. The upper end of the sealing mechanism has a vent for water vapor to be discharged. A hot air blower is installed on the inner side of the heat-insulating shell, and the air outlet of the hot air blower is connected to an air guide mechanism. A mesh plate is provided on the upper side of the air guide mechanism, and a pot body is installed on the outer side of the mesh plate. The sealing mechanism includes a cover body, an installation rod is slidably connected to the inner side of the cover body, and a filter screen cover is fixed to one end of the installation rod facing the pot body; The lower end of the pot body is also equipped with a drive rotation mechanism to drive the pot body to rotate.

[0007] Optionally, the outer side of the pot body is provided with a mounting shell installed inside the heat-insulating shell, and a heating tube is installed on the inner side of the mounting shell.

[0008] Optionally, the filter cover is elastically connected to the cover body via a spring.

[0009] Optionally, the dust collection mechanism includes a connecting ring, and a guide ring is fixed to the inner side of the connecting ring. The longitudinal section of the guide ring is "J" shaped.

[0010] Optionally, the air guiding mechanism includes an air guiding pipe, and a plurality of air outlet pipes are installed on the side of the air guiding pipe facing the pot body. The cross-section of the air guiding pipe is spiral.

[0011] Optionally, the drive rotation mechanism includes a mounting base, a driven wheel rotatably connected to the inner side of the mounting base, the upper end of the driven wheel being fixed to the pot body, a drive wheel meshing with one side of the driven wheel, and the lower side of the mounting base being fixedly connected to the lower end of the drive motor.

[0012] Compared with the prior art, this application has at least the following beneficial effects: 1. Hot air suspension: The spiral air guide mechanism expands the hot air coverage area and evenly blows the tea leaves through the mesh plate, causing them to suspend and separate, avoiding sticking. The heating tube installed in the outer shell directly heats the pot body. When the tea leaves fall and come into contact with the pot, they continue to dehydrate, preventing a sudden drop in temperature. The drive rotation mechanism also drives the pot body to rotate through gear meshing, extending the suspension path of the tea leaves and improving heat exchange efficiency.

[0013] 2. The guide ring of the dust collection mechanism uses airflow to guide debris into the connecting ring groove to avoid secondary pollution. The filter cover is elastically connected to the cover body by a spring, adaptively fitting the edge of the pot body to ensure sealing while allowing water vapor to be discharged through the vent.

[0017] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] The present invention provides a tea drying oven, including an insulated outer shell 1, a dust collection mechanism 2 installed on the upper side of the insulated outer shell 1, and a sealing mechanism 3 bolted to the upper side of the dust collection mechanism 2. The upper side of the insulated outer shell 1 is sealed by the dust collection mechanism 2 and the sealing mechanism 3. The upper end of the sealing mechanism 3 is provided with a steam vent 5 for water vapor to be discharged, so as to avoid excessive humidity inside the insulated outer shell 1 from affecting the drying of tea. A hot air blower 4 is installed inside the heat-insulating shell 1. The air outlet of the hot air blower 4 is connected to a guide mechanism 7. A mesh plate 8 is provided on the upper side of the guide mechanism 7. A pot body 9 is installed on the outer side of the mesh plate 8, so that the tea leaves inside the pot body 9 can be exposed to the hot air vented by the guide mechanism 7 and thus float upward, avoiding the tea leaves from sticking together and affecting the water evaporation efficiency. The outer side of the pot body 9 is provided with a mounting shell 10 installed inside the heat insulation shell 1. A heating tube 11 is installed on the inner side of the mounting shell 10. The heating tube 11 can heat the pot body 9, so that the pot body 9 has a high temperature, and the fallen tea leaves are still dried while in contact with the pot body 9, thus preventing the tea leaves from cooling down. The sealing mechanism 3 includes a cover body 301, and an installation rod 302 is slidably connected to the inner side of the cover body 301. A filter screen cover 303 is fixed to one end of the installation rod 302 facing the pot body 9. The filter screen cover 303 facilitates the discharge of water vapor from the steam outlet 5. The filter cover 303 is elastically connected to the cover body 301 by a spring, so that after the connecting ring 201 is installed with the heat preservation shell 1, the filter cover 303 can keep in close contact with the upper edge of the pot body 9.

[0019] The dust collection mechanism 2 includes a connecting ring 201, and a guide ring 202 is fixed on the inner side of the connecting ring 201. The longitudinal section of the guide ring 202 is "J" shaped. During the hot air drying process of tea, the dust and some particulate matter attached to the surface of the tea due to humidity gradually detach from the surface of the tea as the moisture decreases, and float upward due to the airflow. After being filtered by the filter screen cover 303, it is guided by the shape of the guide ring 202 and enters the groove structure between the connecting ring 201 and the guide ring 202. The air guiding mechanism 7 includes an air guiding pipe 701. Several air outlet pipes 702 are installed on the side of the air guiding pipe 701 facing the pot body 9. The cross-section of the air guiding pipe 701 is spiral, so that the lower side of the mesh plate 8 has a large blowing area, ensuring that the tea leaves on the upper side of the mesh plate 8 can be blown by the airflow. A drive rotation mechanism 6 is also installed at the lower end of the pot body 9 to drive the pot body 9 to rotate. The drive rotation mechanism 6 includes a mounting base 601, and a driven wheel 602 is rotatably connected to the inner side of the mounting base 601. The upper end of the driven wheel 602 is fixed to the pot body 9. A drive wheel 603 is meshed with one side of the driven wheel 602. The lower end of the drive motor 604 is fixedly connected to the mounting base 601 installed on the outside of the heat preservation shell 1. After the drive motor 604 is started, it drives the drive wheel 603 to rotate. The meshing connection between the drive wheel 603 and the driven wheel 602 causes the driven wheel 602 to drive the pot body 9 to rotate, so that the tea leaves in the pot body 9 can rotate. This increases the upward blowing action of the tea leaves, causing them to rise in a spiral shape, further increasing the upward and downward stroke of the tea leaves and improving the drying efficiency.

[0020] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
