Description

Technical Field

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

[0002] Withering is a crucial step in tea processing, directly impacting tea quality. Traditional withering methods primarily rely on natural spreading or simple withering troughs, which have the following drawbacks:

[0003] Uneven turning: Manually turning the tea leaves can easily lead to damage or insufficient uniformity, affecting the fermentation effect;

[0004] Impurities remain: Dust in the tea leaves cannot be effectively separated, reducing the cleanliness of the finished product.

[0005] Although some withering equipment incorporates heating and ventilation functions, problems still exist, such as strong mechanical impact from the tea-turning action and excessive tea leaf dispersion due to overly continuous airflow. Therefore, there is an urgent need for withering equipment that can precisely control temperature, gently turn the tea leaves, and automatically remove dust. Utility Model Content

[0006] Therefore, this application provides a tea withering machine to solve the problems existing in the prior art.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A tea withering machine, comprising:

[0009] The insulation shell has a door panel installed at its opening to seal the inside of the insulation shell. An air pump is installed on the lower side of the insulation shell, and the air outlet of the air pump is connected to several air guide pipes. Several withering and turning mechanisms are installed on the inside of the insulation shell. The air outlet of the air guide pipes is used to turn the tea leaves inside the withering and turning mechanisms. A heating mechanism is provided on one side of the air pump, and part of the air guide pipes is inserted into the heating mechanism. The heating mechanism heats the gas discharged from the air guide pipes.

[0010] The wilting and turning mechanism includes a fixed frame, one end of which is fixedly installed inside the heat-insulating shell. A mesh plate is provided on the upper side of the fixed frame, and side baffles are fixed on both sides of the mesh plate. A cover plate is fixedly installed on the upper end of the fixed frame, and the longitudinal section of the cover plate is wavy.

[0011] Optionally, the inner wall of the withering and turning mechanism is fixed with a mounting frame, and a dust collection trough located on the lower side of the withering and turning mechanism is provided on the upper side of the mounting frame.

[0012] Optionally, a baffle plate is slidably installed on the lower side of the fixing frame. The inner side of the baffle plate has several hole-like structures corresponding to the air outlet of the air duct. A connecting frame is installed at the lower end of the baffle plate. The connecting frame is elastically connected to the heat insulation shell by a spring. A drive plate located on the outside of the heat insulation shell is fixed at one end of the connecting frame. A water droplet wheel is provided in the gap between the drive plate and the heat insulation shell. One end of the water droplet wheel is connected to the output end of the drive motor installed on the outside of the heat insulation shell.

[0013] Optionally, the air pump is further provided with a mounting frame located outside the heat insulation shell, and a filter screen is installed on the inner side of the mounting frame.

[0014] Optionally, the cover plate is mesh-like.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] 1. Airflow is introduced into the withering and turning mechanism through an air pump and air pipe. The airflow gently blows the tea leaves through the mesh plate. Combined with the curved guide of the corrugated cover plate, the tea leaves are automatically turned over, avoiding leaf breakage caused by mechanical squeezing.

[0017] 2. The drive motor drives the water droplet wheel to rotate, which in turn drives the drive plate to reciprocate. This causes the baffle plate to periodically open and close the air outlet of the air duct, and the airflow is sprayed out intermittently. After the tea leaves are blown up, they have enough time to fall back down, which avoids the accumulation or scattering of tea leaves due to continuous airflow and ensures that the withering layer is heated evenly.

Detailed Implementation

[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This utility model provides a tea withering machine, including an insulated outer shell 1, a door panel 2 installed at the opening of the insulated outer shell 1 to close the inner side of the insulated outer shell 1, an air pump 3 installed on the lower side of the insulated outer shell 1, an air outlet of the air pump 3 connected to a plurality of air guide pipes 8, a plurality of withering turning mechanisms 6 installed on the inner side of the insulated outer shell 1, the tea leaves in the withering turning mechanism 6 are turned over by the air outlet of the air guide pipes 8, a heating mechanism 4 is provided on one side of the air pump 3, part of the air guide pipes 8 is inserted into the heating mechanism 4, the heating mechanism 4 heats the gas discharged from the air guide pipes 8 so that it can heat the air blown out by the air guide pipes 8, thereby raising the ambient temperature inside the insulated outer shell 1 and providing a suitable withering environment;

[0028] The wilting and turning mechanism 6 includes a fixed frame 601. One end of the fixed frame 601 is fixedly installed inside the heat insulation shell 1. A mesh plate 602 is provided on the upper side of the fixed frame 601. Side baffles 603 are fixed on both sides of the mesh plate 602. A cover plate 604 is fixedly installed on the upper end of the fixed frame 601. The longitudinal section of the cover plate 604 is wavy.

[0029] When gas is discharged from the outlet of the air duct 8, it blows up the tea leaves on the upper side of the mesh plate 602 through the mesh plate 602. When the tea leaves come into contact with the cover plate 604, the wavy surface of the cover plate 604 makes it very easy to flip the tea leaves.

[0030] The inner wall of the withering and turning mechanism 6 is fixed with a mounting frame 5. The upper side of the mounting frame 5 is provided with a dust collection trough 7 located on the lower side of the withering and turning mechanism 6. After being filtered by the mesh plate 602, it receives the dust present in the tea leaves.

[0031] A baffle plate 11 is slidably installed on the lower side of the fixed frame 601. The inner side of the baffle plate 11 has several hole-like structures corresponding to the air outlet of the air duct 8. A connecting frame 12 is installed at the lower end of the baffle plate 11. The connecting frame 12 is elastically connected to the heat insulation shell 1 by a spring. A drive plate 14 located on the outside of the heat insulation shell 1 is fixed at one end of the connecting frame 12. A water drop wheel 15 is provided in the gap between the drive plate 14 and the heat insulation shell 1. One end of the water drop wheel 15 is connected to the output end of the drive motor 13 installed on the outside of the heat insulation shell 1.

[0032] Specifically, after the drive motor 13 is started, the drive plate 14 rotates. Using the teardrop shape of the water droplet wheel 15, the drive plate 14 is driven to reciprocate. This causes the drive plate 14 to drive the baffle plate 11 to slide back and forth in the fixed frame 601. This causes the perforated structure on the inner side of the baffle plate 11 to intersect with the air outlet of the air duct 8 and perform corresponding reciprocating operations. This allows the air duct 8 to intermittently exhaust air into the withering and turning mechanism 6, providing time for the tea leaves to fall.

[0033] An installation frame 9 is also provided on the outside of the air inlet of the air pump 3, located on the outside of the heat insulation shell 1. A filter screen 10 is installed on the inside of the installation frame 9 to filter the air entering the air pump 3.

[0034] The cover plate 604 is mesh-like, allowing some dust to escape from the cover plate 604.

[0035] 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.
