Description

Technical Field

[0001] The utility model relates to the technical field of tea production, and more specifically to a cooling device for clean tea production. Background Art

[0002] The existing clean production steps of tea are: turning and rinsing, spraying and washing, rotary drying, cold air drying, spreading, grading, withering, preliminary air selection, spreading and airing, preliminary rolling, electric constant temperature flat frying, spreading, rolling, air selection, blending, piling, sufficient drying, finished product, inspection, and warehousing. Among them, withering of tea is a tea-making step in which the oxidase activity in fresh tea leaves is destroyed and passivated by high temperature, the enzymatic oxidation of tea polyphenols in the fresh leaves is inhibited, part of the moisture in the fresh leaves is evaporated, the tea leaves are softened, and it is easy to roll and shape, while emitting a green smell and promoting the formation of a good aroma. However, withering is carried out at high temperature. If the fresh leaves are not cooled in time after withering, the fresh leaves will undergo secondary fermentation, which will affect the color and taste of the tea.

[0003] The existing Chinese patent publication number CN217089388U is a cooling device for clean tea production, which includes a frame, a rotating rod is rotatably connected in the frame, and multiple groups of stirring paddles are fixed on the rotating rod. The left end of the rotating rod passes through the frame and is fixedly connected to a first bevel gear. A second bevel gear is provided on the left side of the first bevel gear, and the first bevel gear is meshed with the second bevel gear. A first motor is axially fixed to the bottom of the second bevel gear. Multiple groups of buffer plates are provided below the rotating rod. The buffer plates are respectively connected to both sides of the frame, and the buffer plates are staggered and matched with each other. A rotating shaft is fixed at the bottom of the buffer plate, and an electromagnet is connected to the left end of the rotating shaft. Ventilation holes are respectively opened on the left and right sides of the frame, and a mounting frame is fixed to the outward extending end of the ventilation hole. A fan is rotatably connected to the mounting frame, and the fan is externally connected to the second motor. A conveying plate is provided below the buffer plate, and the conveying plate is fixed to the inner wall of the frame. A discharge port is provided on the right side of the frame, and a material receiving box is provided on the right side of the discharge port. A cooling pipe is provided in the frame, and the cooling pipe is fixed to the front end of the back facade of the frame.

[0004] During the use of the above device, when tea leaves fall from one set of buffer plates to another set of buffer plates, they pile up and fall together due to their own gravity and the inclination angle of the buffer plates, resulting in the airflow being unable to effectively contact the piled tea leaves, thereby reducing the cooling effect.

When the output end of the motor 2 16 rotates, the worm 2 36 outside its output end drives the rotating shaft 17 to rotate through the worm gear 2 35. The rear end of the rotating shaft 17 drives the connecting plate 18 to move back and forth inside the rectangular groove 1 21 through the protrusion. The other end of the connecting plate 18 drives the inclined plate 23 to move up and down along the rotating shaft 2 22, so that the tea leaves are shaken off the inclined plate 1 23. In the process of the tea leaves falling from the inclined plate 2 29 to the inclined plate 1 23 and shaking from the inclined plate 1 23, the tea leaves will be fully in contact with the external air, thereby improving the cooling efficiency of the tea leaves.
