[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea tree. Tea ingredients include catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are good for health. Tea can be divided into primary processing (primary processing), refined (fine processing), reprocessing and deep processing according to different processing processes. Tea leaves are formed into different types of tea due to different processing techniques. The formation of the quality of each type of tea depends on the coordination of the processing procedures; only under excellent processing conditions can high-quality fresh leaf raw materials produce various types of high-quality tea leaves. Usually, the processing of tea leaves includes withering, making green, frying green, rolling, drying, etc. The artificial rolling makes the water in the tea leaves evaporate quickly, blocking the fermentation process of the tea leaves and fully retaining the essence of the tea juice.

DETAILED DESCRIPTION Example
[0021] like Figure 1-Figure 5 As shown, a tea screening and drying machine proposed in this embodiment includes a frame 1, a baking frame 3, a sliding plate 4, a heater 5, a closed door 7, a mounting frame 9, a driving rod 10, a screening cylinder 11 and a motor 13.
[0022] The frame 1 has a baking chamber 101, a material discharge chute 102, a conveying channel 103 and a screening chamber 105. The baking rack 3 is slidably arranged at the baking chamber 101. The sliding plate 4 is slidably arranged on the baking rack 3. A plurality of heaters 5 are arranged at the top of the baking chamber 101. The baking chamber 101, the material discharge chute 102, the conveying channel 103 and the screening chamber 105 are connected in sequence. The closed door 7 is rotatably sealed and arranged at the screening chamber 105. The mounting frame 9 is arranged in the screening cylinder 11, and the mounting frame 9 is connected to the conveying channel 103. The motor 13 is arranged on the frame 1, and the motor 13 is connected to the driving rod 10 for driving. The screening cylinder 11 is rotatably and detachably arranged on the mounting frame 9, and the end of the driving rod 10 away from the motor 13 is connected to the screening cylinder 11.
[0023] The frame 1 also has a storage chamber 104, which is detachably provided with a storage box 6. The storage chamber 104 is connected to the conveying channel 103 at the top of the storage chamber 104. When the tea leaves are put into the baking chamber 101 for baking, some soil and wood blocks remain in the tea leaves. After the tea leaves are baked, the tea leaves are transported in the conveying channel 103 and enter the mounting frame 9 and the screening cylinder 11 in turn, and the soil and wood blocks in the tea leaves will fall into the storage chamber 104, reducing the probability of the tea leaves being contaminated by the taste of the soil and wood blocks, thereby improving the baking quality of the tea leaves.
[0024] When this embodiment is used, the worker puts the tea leaves on the sliding plate 4 of the baking rack 3, then pushes the baking rack 3 into the baking chamber 101, turns on the heater 5 to dry the tea leaves, and then after the tea leaves are baked and hardened, the sliding plate 4 is moved, and the tea leaves on the sliding plate 4 fall into the discharge chute 102, and the tea leaves fall into the screening cylinder 11 along the discharge chute, the conveying channel 103 and the mounting frame 9, and the heated air also enters the screening chamber 105 along the tea leaves, and then the motor 13 drives the driving rod 10 to rotate, and the driving rod 10 drives the screening cylinder 11 to rotate, and then the tea leaves are fully contacted with the heated air during the rotation process, thereby performing secondary drying and improving the drying quality of the tea leaves. After the drying is completed, the closed door 7 is opened, and the worker takes out the screening cylinder 11 from the closed door 7 and pours the tea leaves out of the screening cylinder 11. Example
[0025] like Figure 2-Figure 5 As shown, a tea screening and drying machine proposed in this embodiment, compared with the first embodiment, in this embodiment, the mounting frame 9 has a mounting frame main body 91, a feed port 92 and a fixed frame portion 93, the feed port 92 is arranged at one end of the mounting frame main body 91 close to the motor 13, the frame 1 has a supporting platform portion 106, two supporting platforms 106 are arranged opposite to each other in the screening chamber 105, the mounting frame main body 91 is arranged on the two supporting platforms 106, the mounting frame main body 91 is cylindrical, and a plurality of fixed frame portions 93 are arranged along a ring on the inner surface of the mounting frame main body 91, and a fixed block 12 is rotatably arranged on each of the plurality of fixed frame portions 93, and the fixed block 12 is cylindrical.
[0026] A fan 14 is provided in the conveying channel 103, and the fan 14 faces the feed inlet 92. When the tea leaves move to the fan 14, the fan 14 will blow the tea leaves toward the feed inlet 92, and the soil and wood blocks in the tea leaves will fall into the storage box 6 due to their own high weight and are difficult to blow away, thereby performing preliminary screening of the tea leaves, thereby ensuring the quality of the tea leaves.
[0027] In this embodiment, the tea leaves move to the feed inlet 92 through the conveying channel 103, and then move from the feed inlet 92 to the screening cylinder 11. The screening cylinder 11 rotates on the mounting frame body 91, and the fixing blocks 12 on the multiple fixing frame parts 93 clamp the screening cylinder 11, so that the screening cylinder 11 can rotate stably. The fine broken leaves or dust flying out of the screening cylinder 11 will be blocked by the mounting frame body 91, and then fall under the mounting frame body 91, thereby improving the drying quality of the tea leaves. Example
[0028] like Figure 2 , Figure 3 and Figure 5As shown, a tea screening and drying machine proposed in this embodiment, compared with the first embodiment, in this embodiment, the screening cylinder 11 includes a fixed plate 111, a feed ring 112 and a filter screen 113, the filter screen 113 is in a circular shape, and the two ends of the filter screen 113 are respectively connected to the fixed plate 111 and the feed ring 112, the driving rod 10 is connected to the fixed plate 111, and a plurality of fixed blocks 12 are in sliding contact with the outer peripheral surface of the screening cylinder 11 along the ring shape, and a discharging rack 8 is slidably and detachably provided at the bottom of the screening cavity 105, and the discharging rack 8 is located below the mounting frame 9, and the tea leaves are tumbled in the screening cylinder 11. During the tumbling process, the fine dust and fine tea leaves in the tea leaves fall out with the mesh holes of the filter screen 113, and then the dust and tea leaves are blocked by the mounting frame main body 91, and thus fall into the discharging rack 8 at the bottom of the mounting frame main body 91, and the worker can take out the discharging rack 8 to pour out the debris, reduce the contact between the tea leaves and the dust, and thus ensure the quality of the tea leaves.
[0029] In this embodiment, the tea leaves pass through the feed ring 112 along the feed opening 92 and enter the filter screen 113, and then the driving rod 10 drives the fixed disk 111 to rotate. The feed ring 112 and the fixed disk 111 are connected by a connecting rod, thereby ensuring the stability of the screening cylinder 11 structure. Smaller tea debris will be discharged from the screening cylinder 11 through the mesh of the filter screen 113, avoiding secondary screening by workers and reducing the workers' work intensity. Example
[0030] like Figure 1-Figure 4 As shown, a tea screening and drying machine proposed in this embodiment is compared with the first embodiment. In this embodiment, a control panel 2 is provided on the frame 1, and the control panel 2 is electrically connected to the heater 5, the motor 13 and the fan 14 respectively.
[0031] In this embodiment, after the worker pours the tea leaves onto the sliding plate 4, the worker controls the heater 5 and the fan 14 through the control panel. After the preliminary drying of the tea leaves is completed, the fan 14 will blow the tea leaves into the screening cylinder 11, and then dry the tea leaves with the cooperation of the heater 5 and the motor 13, so that the tea leaves are dried more evenly, thereby improving the quality of the tea leaves.
[0032] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
