Description

Technical Field

[0001] This utility model relates to an automatic drying device for gardenia flower compound substitute tea. Background Technology

[0002] Patent CN221172848U discloses a high-quality gardenia tea drying device, including a main body with bases on all four sides of its bottom. An exhaust fan is embedded in the top of the main body, and the exhaust fan is connected to the main body. A movable door is located on the front of the main body. Three drying plates arranged longitudinally at equal intervals are fixedly connected inside the main body. A scraper is fixedly connected to a rotating shaft on one side above the drying plates. When the motor is started, it drives the rotating shaft to rotate, which in turn drives the scraper. The scraper's rotation agitates the gardenia flowers placed on the drying plates. The angled scraper easily flips the gardenia flowers, increasing drying efficiency.

[0003] The above structure is more suitable for drying flower tea. However, the main raw material of gardenia flower compound substitute tea is gardenia flower, which is relatively fragile and its aroma is not as long-lasting as tea leaves. If the drying box with the above structure is used to dry the raw material of gardenia flower compound substitute tea, the scraper will easily cause the raw material to break. Moreover, the aroma of the raw material will be continuously lost during the drying process, resulting in a weak aroma in the final product. Utility Model Content

[0019] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] Combination Figure 1-3As shown, an automatic drying device for gardenia compound substitute tea includes a drying box 1 and multi-layer drying trays 2 arranged at the same height inside the drying box 1.

[0021] Each of the drying trays 2 has a hot air output pipe assembly 3 installed in the drying chamber 1 below it. The air outlet 4 of each hot air output pipe assembly 3 is set downwards. One end of each hot air output pipe assembly 3 is connected to a hot air blower installed outside the drying chamber 1.

[0022] The top of the drying chamber 1 is provided with an exhaust port 5, and the exhaust port 5 is provided with a three-way valve 6. The three-way valve 6 is also connected to a desiccant box 7. The desiccant box 7 is connected to a circulating pump 8 through a connecting pipe. The circulating pump 8 is connected to the other end of each group of hot gas output pipe groups 3 through a connecting pipe.

[0023] The working principle of the above structure is as follows: The raw materials of the gardenia compound substitute tea are evenly spread on each drying tray 2, then each drying tray 2 is placed inside the drying chamber 1, the chamber door is closed, and the hot air blower is turned on. The hot air blower outputs hot air at 35℃-65℃ for 50 minutes. The hot air is blown downwards onto the drying trays 2 through the air outlets 4 of each hot air output pipe group 3, and then discharged from the exhaust port 5 at the top of the drying chamber 1, drying the raw materials on each drying tray 2. The raw materials on each drying tray 2 gradually dehydrate, and during the dehydration process, water vapor is discharged from the drying chamber 1 with the hot air. Afterwards, the hot air blower outputs hot air to quickly raise the temperature inside the drying chamber 1 to 85-95℃. After reaching a certain temperature, the gas supply is stopped, and the raw materials are rapidly heated to ensure thorough drying and enhance aroma. During this process, the three-way valve 6 closes the exhaust port 5, and the circulation pump 8 is turned on. The air in the drying chamber 1 circulates within the drying chamber 1 through the desiccant box 7 and the circulation pump 8. During the circulation, a small amount of moisture in the air is absorbed by the desiccant box 7, ensuring the drying effect on the raw materials. Meanwhile, the aroma generated by the raw materials during heating is not released, maximizing the preservation of the flavor of the gardenia compound substitute tea. After the hot air circulates in the drying chamber 1 for 10 minutes, the circulation pump 8 is turned off. After cooling for 15 minutes, the chamber door is opened, and the dried gardenia compound substitute tea is removed.

[0024] The beneficial effects of the above structure are: it is simple in construction, can thoroughly dry gardenia compound substitute tea, and can maximize the preservation of the flavor of gardenia compound substitute tea; in particular, each hot air output pipe group 3 exhausts downward, so that the hot air has a downward and then upward flow process, which can make the temperature distribution in the drying box 1 more uniform, thereby making the raw materials on each drying tray 2 evenly dehydrated and dried, so as to ensure the quality of the final product.

[0025] In another embodiment, such as Figure 3 As shown, the drying tray 2 consists of a frame 9 and a mesh plate 10 disposed inside the frame 9 to facilitate the passage of hot air.

[0026] In another embodiment, combined Figure 1 and Figure 2 As shown, the drying oven 1 is provided with brackets 11 on both inner sides, and the drying tray 2 is placed on the corresponding brackets 11 on both sides.

[0027] In another embodiment, combined Figure 1 and Figure 2 As shown, the drying oven 1 is provided with a double layer 12 on both sides. The two ends of each hot air output pipe group 3 are connected to the two double layers 12 respectively. The hot air blower and the circulating pump 8 are also connected to the two double layers 12 through connecting pipes. The two double layers 12 form air transmission channels respectively. The two double layers 12 also play a role in heat preservation.

[0028] In another embodiment, such as Figure 2 As shown, the drying oven 1 is also provided with a heat insulation layer 13 on the outside.

[0029] In another embodiment, combined Figure 1 and Figure 2 As shown, the hot air output pipe group 3 consists of a main pipe 14 at both ends and multiple branch pipes 15 connected between the main pipes 14. The two main pipes 14 are connected to the two interlayers 12 through multiple interfaces, and multiple air outlets 4 are provided at the bottom of each branch pipe 15.

[0030] In another embodiment, the drying oven 1 is also provided with a door on the front.

[0031] In another embodiment, the air inlet of the hot air blower is also equipped with a filter to prevent external dust from entering the drying chamber 1.
