The solid plate on the stirring device 204 is in contact with the inner wall of the drying cylinder 203, and an opening and closing plate 202 is contactingly installed on the drying cylinder 203. An opening and closing cylinder 201 is fixedly installed on the inner wall of the heating box 103, and the opening and closing plate 202 is fixedly installed on the movable end of the opening and closing cylinder 201. A switch plate 104 is also rotatably installed on the heating box 103, and the switch plate 104 is used to facilitate the addition of tea raw materials. A side metal dense mesh 205 is also fixedly installed on the drying cylinder 203, and the installation position of the side metal dense mesh 205 on the drying cylinder 203 is set corresponding to the air inlet duct 106. The drying cylinder 203 is also fixedly installed with an auxiliary filter plate 206, and the auxiliary filter plate 206 is provided with multiple A main filter plate 207 is fixedly installed outside the drying cylinder 203, and the main filter plate 207 is fixedly connected to the heating box 103.

A heating wire 105 for heating the air flow is also fixedly installed in the heating box 103. The heating wire 105 is arranged between the main filter plate 207 and the air inlet pipe 106 to heat the passing air flow. In this way, the air flow is driven into the air inlet pipe 106 by the front air flow driving module 107, and the air flow is heated by the heating wire 105 from the air inlet pipe 106. Then, the air flow enters the drying cylinder 203 from the main filter plate 207, the auxiliary filter plate 206, and the side metal dense mesh 205. At this time, the stirring device 204 can also rotate, so that the stirring device 204 can stir the material in the drying cylinder 203, thereby accelerating the drying process.

[0024] like Figures 2 to 6As shown, the inner wall of the heating box 103 is also rotatably mounted with a side metal mesh 209, the side metal mesh 209 is in contact with the drying cylinder 203, a rotation torsion spring is fixedly mounted on the side metal mesh 209, and the other end of the rotation torsion spring is fixedly mounted on the inner wall of the heating box 103, the side metal mesh 209 away from the axis of the drying cylinder 203 is fixedly mounted with an outer branch groove 210, the outer branch groove 210 is in the shape of a slide groove, the drying cylinder 203 is also fixedly mounted with a leakage metal mesh 208 for releasing liquid in the raw material, the inner wall of the drying cylinder 203 is connected with the side metal mesh 209, the opening and closing plate 202, the side metal dense mesh 205, and the leakage metal mesh 2 08 together form a drying chamber, which is circular, the opening and closing plate 202 in the chamber is the material inlet, the side metal mesh 205 is the airflow inlet, the side metal mesh 209 is the material outlet and the airflow outlet, the leakage metal mesh 208 is the leakage point of the liquid carried by the raw material, and the angle between the side metal mesh 209 and the side metal mesh 205 in the drying chamber is one hundred and thirty degrees. When the material is stirred in the drying cylinder 203, the airflow passes through the side metal mesh 205 and enters the drying cylinder 203 to dry the raw materials. After passing through the drying cylinder 203, the airflow flows out of the device from the side metal mesh 209, and the airflow leaves from the air outlet pipe 102 at this time.

[0025] like Figure 2 and Figures 4 to 6 As shown, a conveying device 213 is arranged in the heating box 103, and the conveying device 213 is composed of a transmission belt and two sets of pulleys. A rotating rod 211 is also rotatably installed on the inner wall of the heating box 103. One end of the rotating rod 211 is arranged in the outer branch groove 210, and the other end of the rotating rod 211 is frictionally connected with the pulley in the conveying device 213. The purpose of this is to allow the conveying device 213 to drive the rotating rod 211 to rotate after starting, and the rotation axis of the rotating rod 211 is the axis of a pulley on the conveying device 213 close to the air outlet pipe 102.

[0027] Working principle: This device drives the airflow in the device to circulate through the front airflow drive module 107 and the rear airflow drive module 110, and the rotating screw 108 can adjust the position of the front airflow drive module 107 relative to the air inlet pipe 106. The purpose of this is to adjust the airflow flow rate. After the airflow enters the air inlet pipe 106, it is heated by the heating wire 105 and filtered by the main filter plate 207 and the auxiliary filter plate 206. Then, the airflow passes through the side metal mesh 205 and enters the drying cylinder 203. At this time, the tea leaves in the drying cylinder 203 will be dried by the hot air flow, and the turning device 204 will rotate to continuously turn the tea leaves through the stirring claws and the solid plate to accelerate the drying of the tea leaves.

[0028] The liquid in the tea material in the drying drum 203 will be continuously sent to the bottom of the drying drum 203, and the liquid leakage metal mesh 208 on the drying drum 203 will allow the liquid to leave the drying drum 203, so that the tea material in the drying drum 203 can be quickly dried. After the tea material is dried, the conveying device 213 can be started, and the transmission belt on the conveying device 213 can start working. When the pulley on the conveying device 213 rotates, the pulley will drive the rotating rod 211 to rotate, so that the rotating rod 211 can rotate. Figure 4 The rotating rod 211 rotates counterclockwise, and the rotating rod 211 drives the side metal mesh 209 to rotate, allowing the side metal mesh 209 to open the space in the drying cylinder 203, allowing the dried tea raw materials to fall out of the drying cylinder 203, and the tea leaves will fall into the finished product chamber. In this case, the stirring device 204 also needs to continue to rotate, and its purpose is to allow the solid plate on the stirring device 204 to drive the tea raw materials in the drying cylinder 203 out, and then the dried tea raw materials placed in the raw material chamber will be transported by the conveying device 213, and the conveying device 213 will drive them into the storage box 109 for storage. It is worth mentioning here that when the rotating rod 211 rotates, it will also slide in the outer branch groove 210 when squeezing the outer branch groove 210, so as to prevent the rotating rod 211 from being stuck.

[0029] After all the dried tea leaves in the drying cylinder 203 are driven out, the side metal mesh 209 can be closed, and then the opening and closing cylinder 201 can be started to open the opening and closing plate 202, so that the tea leaves in the raw material chamber can enter the drying cylinder 203, and then the cycle can be carried out. The blocking net 111 is used to prevent the tea leaves in the finished product chamber from escaping from the finished product chamber.
