Description

Technical Field

[0001] This utility model relates to the field of tea processing, and in particular to a tea sterilization device. Background Technology

[0002] Sterilization is a crucial step in tea production, directly impacting the quality and taste of the tea. Traditional tea sterilization methods primarily involve high-temperature drying or ultraviolet (UV) irradiation. Many tea sterilization devices exist on the market; for example, CN219537348U discloses a UV sterilization device for tea processing, which uses a combination of a UV lamp fixed inside an outer casing and a rotating storage box. However, relying solely on UV lamps inside the outer casing and through the sliding door can easily create blind spots when tea is piled up, resulting in uneven sterilization. Utility Model Content

[0004] Therefore, the technical solution of this utility model is: a tea sterilization device, including a box body, the box body having a cavity; the cavity having a rotating shaft and a drive motor for driving the rotating shaft to rotate; the rotating shaft having multiple fixing blocks, each fixing block having a tray inserted thereon; the side wall of the cavity having multiple ultraviolet lamp columns facing the center of the rotating shaft and located above each tray.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the tray has a hollow structure with a U-shaped opening in the middle; the U-shaped opening has a protruding retaining strip, and the fixing block of the rotating shaft has retaining grooves on both sides, with the retaining strip inserted into the retaining grooves, and the two are interference fit.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the cavity is provided with multiple lamp post interfaces, and the ultraviolet lamp posts are installed on the lamp bead interfaces; the outside of the cavity is provided with a circuit control board, which is electrically connected to the lamp post interfaces.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: a partition is provided below the cavity, the drive motor is located below the partition, and the partition is provided with an opening for the rotating shaft to pass through.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: a fan is provided below the partition, an air intake is provided on the partition, and a filter is provided on the air intake; the inlet end of the fan is connected to the air intake, and the outlet end is connected to the exhaust pipe; an air inlet is provided above the cavity, and a HEPA filter is provided at the air inlet.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. The rotating shaft drives the tray to rotate, and combined with the ultraviolet lamp column above each tray, the tea can be exposed to ultraviolet light from all directions, avoiding sterilization dead spots; the hollow tray design further enhances light penetration, greatly improving the uniformity and efficiency of sterilization. At the same time, ultraviolet sterilization will not damage the nutritional components and flavor of the tea, thus better preserving the original quality of the tea.

[0011] 2. The pallet is secured by a U-shaped opening with a locking strip on the top and a slot on the rotating shaft, making loading and unloading convenient and secure, thus improving operational convenience and stability.

[0012] 3. The ultraviolet lamp column is installed through the lamp column interface, which is convenient for replacement and maintenance. The circuit control board is electrically connected to the lamp column interface, which can flexibly control the switching on and off of the ultraviolet lamp column and the working time. The cavity and the drive motor are separated by a partition, which is compact and reasonable in layout, reducing the impact of motor operation on the internal environment of the cavity.

[0013] 4. The air inlet at the top of the chamber is equipped with a HEPA filter to filter the incoming air and prevent external pollutants from entering; the fan below the partition, together with the air intake, can promptly expel odors and moisture generated by ultraviolet sterilization, keeping the chamber dry and clean and preventing secondary contamination of the tea during the sterilization process.

[0023] See the attached drawings. The tea sterilization device described in this embodiment includes a box 1, which is a rectangular structure with an operating door 11 on the front side; the box 1 has a cavity 2 inside, and the inner side of the cavity 2 is an arc-shaped sidewall 21; the cavity 2 has a partition 3 inside, which divides the cavity 2 into upper and lower parts; the cavity 2 has a rotating shaft 4 inside, and the partition 3 has a mounting hole for the lower end of the rotating shaft 4 to pass through, the lower end of the rotating shaft 4 passes through the mounting hole (a bearing is installed in the mounting hole), and is connected to a drive motor 5 (which can be connected via a gear set) below the partition.

[0024] The rotating shaft 4 is provided with multiple fixing blocks 41, and the fixing blocks 41 have slots 42 on both sides. Rubber gaskets are provided in the slots 42. Each fixing block 41 can be fitted with a tray 6. The tray 6 has a hollow structure with a U-shaped opening 61 in the middle and a protruding retaining strip 62 on the U-shaped opening 61. When installing the tray 6, the U-shaped opening 61 is aligned with the fixing block 41 and inserted, so that the retaining strip 62 is inserted into the slot 42. The two are interference-fitted, and the rubber gasket of the slot 42 can also increase the friction to prevent the tray 6 from slipping.

[0025] The cavity 2 has multiple lamp post interfaces 22 on its arc-shaped sidewall 21, and ultraviolet lamp posts 7 are installed on the lamp bead interfaces 22. One end of the ultraviolet lamp post 7 is fixed to the lamp post interface 22, and the other end extends into the center of the tray 6. At least one ultraviolet lamp post 7 is provided above each layer of tray 6. A circuit control board 8 is provided on the outside of the cavity 2, which is electrically connected to the lamp post interface 22. The circuit control board 8 can be used to control the brightness of the ultraviolet lamp posts 7.

[0026] A fan 9 is located below the partition 3, and the fan 9 is controlled by the circuit control board 8. An air intake 91 is located on the partition 3, and a filter screen is located on the air intake 91. The inlet end of the fan 9 is connected to the air intake 91, and the outlet end is connected to the exhaust pipe 92. An air inlet is located above the cavity 2, and a filter 10 with a HEPA filter screen is installed at the air inlet.

[0027] The usage process is as follows:

[0028] 1) Check the status of each component of the device to ensure that the ultraviolet lamp column 7 is installed securely, the circuit control board 8 is normal, and the fan 9 and filter are not blocked;

[0029] 2) Spread the tea leaves to be sterilized evenly on the perforated tray 6, taking care to avoid piling the tea leaves too thickly and affecting the light exposure;

[0030] 3) Install the tray 6 containing tea leaves into the slot 62 of the corresponding fixing block 61 through the U-shaped opening 61;

[0031] 4) After confirming that all trays 6 are installed in place, close the operating door 11.

[0032] 5) Start the device via the circuit control board, drive the motor to start working, and drive the rotating shaft and tray to rotate at a constant speed; at the same time, the circuit control board controls the ultraviolet lamp column to turn on, and sterilize the rotating tea leaves with ultraviolet light.

[0033] 6) During the sterilization process, the fan 9 starts simultaneously; outside air enters the cavity through the air inlet (filtered by HEPA filter) above the cavity 2 to maintain internal air circulation; the air inside the cavity 2 (containing odors and a small amount of water vapor) is drawn in by the fan 9 through the air inlet 91 (filtered by filter) on the partition 3, and then discharged through the exhaust pipe 92 to achieve air circulation and purification.

[0034] 7) After the preset sterilization time is reached, the circuit control board 8 automatically shuts off the ultraviolet lamp column 7, drive motor 5, and fan 9. After the device has completely stopped running, open the operating door 11, remove the tray 6, and the tea sterilization operation is completed.
