Description

Technical Field

[0001] This utility model belongs to the field of tea drying technology, specifically relating to a filter device for uniformly dispersing tea leaves in Dongbai cold brew tea. Background Technology

[0002] Dongbai cold-brewed tea is a type of tea produced in Dongbai Mountain. Cold-brewed tea is typically made by steeping tea leaves in cold water for an extended period of time. Spreading and drying is a crucial step in the tea production process. Spreading and drying fresh tea leaves allows the moisture in the leaves to evaporate naturally, softens the leaves, makes them less prone to breakage during the initial processing (kill-green), and removes any grassy odor.

[0003] The existing tea-drying process generally involves manually spreading the tea leaves on a drying net, which results in poor uniformity of distribution, low distribution efficiency, and high labor intensity. Utility Model Content

[0004] The purpose of this invention is to provide a filter device for uniformly dispersing Dongbai cold-brewed tea leaves, thereby solving the problems mentioned in the background art. The filter device for uniformly dispersing Dongbai cold-brewed tea leaves provided by this invention features good tea leaf dispersion uniformity, high dispersion efficiency, and low labor intensity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter screen device for uniformly dispersing tea leaves in Dongbai cold brew tea, including a conveyor belt, a dispersing mesh frame placed above the conveyor belt, a hopper located above the middle of the conveyor belt, a feeding roller installed at the discharge end of the hopper, and a reduction motor for driving the feeding roller installed on the hopper.

[0006] To further guide the movement of the dispersed mesh frame, guide plates are installed on both sides above the conveyor belt.

[0007] To limit the distribution mesh frame conveyed to the end of the conveyor belt and prevent it from falling off due to failure of staff to remove it in time, a limit baffle is further installed above the discharge end of the conveyor belt, with the bottom surface of the limit baffle being higher than the upper surface of the conveyor belt.

[0008] In order to push the tea leaves downwards from the hopper, prevent the tea leaves from clogging the discharge end of the hopper, and ensure the uniformity of the tea leaf drop, the pushing roller further includes a shaft body, and several pushing rods are provided on the circumference of the shaft body.

[0009] To ensure a flexible contact between the lever and the tea leaves and avoid damage to the tea, the lever is made of rubber.

[0010] To increase air circulation and thus shorten the drying time, the dispersing frame further includes a frame body, inside which alternately arranged first and second filters are installed, with the installation height of the first filter being higher than that of the second filter.

[0011] To prevent tea leaves from piling up on the frame, the upper part of the frame is further provided with an inward slope.

[0012] In order to collect small tea leaves or impurities that fall onto the conveyor belt after passing through the filter, a collection box is further placed below the discharge end of the conveyor belt.

[0013] To ensure the smooth support of the conveyor belt and allow the dispersed mesh frame to move horizontally, several support shafts located on the bottom surface of the upper conveyor belt are further installed inside the conveyor belt.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a conveyor belt to drive the dispersing mesh frame to move at a uniform speed, and the action of the feeding roller to evenly push the tea leaves in the hopper onto the dispersing mesh frame, thereby achieving uniform dispersion of the tea leaves in the dispersing mesh frame. Compared with manually dispersing the tea leaves, it has the effects of good dispersion uniformity, high dispersion efficiency and low labor intensity.

[0016] 2. This utility model uses a lever to push the tea leaves in the hopper downwards, which can prevent the tea leaves from clogging the discharge end of the hopper and ensure the uniformity of the tea leaves falling.

[0017] 3. The lever of this utility model is made of rubber, which makes flexible contact between the lever and the tea leaves, thus avoiding damage to the tea leaves.

[0018] 4. This utility model alternates between the height of the first and second filters, which can increase air circulation and thus shorten the drying time. Attached Figure Description

[0029] By adopting the above technical solution, the movement of the distributed grid frame 2 is guided.

[0030] Specifically, a limit baffle 5 is installed above the discharge end of conveyor belt 1.

[0031] By adopting the above technical solution, the dispersed mesh frame 2 conveyed to the end of the conveyor belt 1 is limited to prevent it from falling off due to the staff not taking it away in time.

[0032] Specifically, the feeding roller 8 includes a shaft 81, and a number of levers 82 are provided on the circumference of the shaft 81. The diameter of the levers 82 is 2-3mm.

[0033] By adopting the above technical solution, the tea leaves in the hopper 3 are pushed downward by the lever 82, which can prevent the tea leaves from clogging the discharge end of the hopper 3 and ensure the uniformity of the tea leaf discharge.

[0034] Specifically, lever 82 is made of rubber.

[0035] By adopting the above technical solution, the lever 82 makes flexible contact with the tea leaves, thus avoiding damage to the tea leaves.

[0046] By adopting the above technical solution, the smoothness of the support of the conveyor belt 1 is ensured, so that the distributed mesh frame 2 can move horizontally.

[0047] In summary, this invention uses a conveyor belt 1 to drive the dispersing frame 2 at a uniform speed, and the action of the feeding roller 8 to evenly distribute the tea leaves from the hopper 3 onto the dispersing frame 2, thus achieving uniform dispersion of the tea leaves within the dispersing frame 2. Compared to manual dispersion, this invention offers advantages such as better dispersion uniformity, higher dispersion efficiency, and lower labor intensity. The invention also uses a lever 82 to push the tea leaves downwards from the hopper 3, preventing clogging at the outlet and ensuring uniform distribution. The lever 82 is made of rubber, providing flexible contact between the lever and the tea leaves and preventing damage. Furthermore, the alternating heights of the first filter screen 22 and the second filter screen 23 increase airflow, thereby shortening the drying time.
