[0002] Tea refers to the leaves and buds of the tea tree, which can be used to make tea. Tea contains a variety of ingredients that are beneficial to health, such as catechins, caffeine, folic acid, etc. It needs to be withered during the tea making process. It is mainly through high temperature destruction and passivation of the oxidase activity in the fresh leaves, inhibiting the enzymatic oxidation of tea polyphenols in the fresh leaves, preventing discoloration during the drying process, and emitting a green smell, promoting the formation of a good aroma. Withering is the first key step in tea making, and the quality of withering determines the quality of the tea.

[0003] Most existing methods of withering tea leaves involve putting new tea leaves into a hot pot. The sudden increase in temperature may result in uneven withering of the tea leaves. Some tea leaves may be over-withered, while others may be under-withered, which may cause the tea leaves to have a smoky smell. Since the temperature cannot be controlled, it may take longer to complete the withering process, thus affecting production efficiency.

[0004] Therefore, in view of the above-mentioned existing withering methods, most of them are to put the new tea leaves into a hot pot. Since the temperature is uncontrollable, it may cause uneven withering of the tea leaves, making the tea leaves have a smoky smell, thereby affecting production efficiency. A digital electromagnetic superheated steam tea drum withering machine can be designed, which uses electromagnetic superheated steam drum type withering to make the temperature of the tea leaves uniform and controllable during withering.

The heat coil 204 and the operation panel 201 are provided with a battery pack 209 connected to the electromagnetic heating coil 204 on one side, a rectangular sealing cover 207 is provided above the outer box body 2, and an outlet pipe 210 is installed on the upper end of the rectangular sealing cover 207. The outlet pipe 210 passes through the outer shell 1 and extends into the interior thereof at one end away from the rectangular sealing cover 207. A first telescopic valve 211 is provided at the connection between the outlet pipe 210 and the rectangular sealing cover 207, and an air intake pipe 213 fixedly connected to the rectangular sealing cover 207 is provided on one side of the outlet pipe 210. A second telescopic valve 214 is provided at the connection between the air intake pipe 213 and the rectangular sealing cover 207. The air intake pipe 213 passes through the outer shell 1 and extends into the interior thereof at one end away from the rectangular sealing cover 207. An air pump 216 is provided at the connection between the air intake pipe 213 and the outer shell 1.

[0023] See also Figure 2-Figure 3 In this embodiment, a connecting shaft 104 is installed on the side of the outer shell 1 away from the outer box body 2, and the opening and closing plate 101 is rotatably connected to the outer shell 1 through the connecting shaft 104. By pulling the handle 103, the opening and closing plate 101 is opened, and the tea leaves are placed in the inner cylinder 105, which is convenient for drum-type withering. A return rubber ring 102 is installed on the edge of the opening and closing plate 101 close to the outer shell 1, and a handle 103 is installed on the side of the opening and closing plate 101 away from the outer shell 1. When all the tea leaves are placed, the handle 103 is pushed, and the opening and closing plate 101 is rotated and closed with the outer shell 1 through the connecting shaft 104. At the same time, the return rubber ring 102 drives the opening and closing plate 101 to fit along the inner wall of the outer shell 1 and connects with it, increasing the sealing and preventing steam leakage during withering.

[0024] See also Figure 4In this embodiment, a circular groove is formed between the inner box body 203 and the outer box body 2. A temperature sensor 202 (model of the temperature sensor 202 is JASUN-M12) fixedly connected to the outer box body 2 is provided on the side of the operation panel 201 away from the battery pack 209. Through the control of the operation panel 201 and the drive of the battery pack 209, the electromagnetic heating coil 204 begins to emit heat, heating the water source to generate steam. At the same time, the steam temperature is detected by the temperature sensor 202 and then reflected to the operation panel 201. On the side of the outer box body 2 away from the outer box body 1, a water inlet pipe 205 is installed that passes through the outer box body 2 and extends into the inner box body 203. A circular sealing cover 206 is provided on the outer side of the water inlet pipe 205 away from the outer box body 2. First, loosen the circular sealing cover 206, pour the water source into the inner box body 203 through the water inlet pipe 205, and then tighten the circular sealing cover 206. A circular clipping plate 208 is installed at the lower edge of the rectangular sealing cover 207 corresponding to the circular groove. The circular clipping plate 208 drives the rectangular sealing cover 207 to fit along the circular groove with the inner box body 203 and the outer box body 2 When the inner box body 203 needs to be cleaned or repaired, the rectangular sealing cover 207 is opened. After the cleaning or repair is completed, the return-shaped clamping plate 208 drives the rectangular sealing cover 207 to fit the inner box body 203 and the outer box body 2 along the return-shaped groove. A first electromagnetic control valve 212 (the model of the first electromagnetic control valve 212 is AD-8A-N-G1) is installed on the outer side of the first telescopic valve 211, and a second electromagnetic control valve 215 is installed on the outer side of the second telescopic valve 214. When the appropriate temperature is reached, the first electromagnetic control valve 212 is connected to the outer box body 203. Under the control of the valve control valve 212, the first telescopic valve 211 is opened, and the steam enters the outer shell 1 through the outlet pipe 210. When the tea leaves are withered, the battery pack 209 is turned off, the heating to generate steam is stopped, and the first telescopic valve 211 is closed. Then, under the control of the second electromagnetic control valve 215, the second telescopic valve 214 is opened. At the same time, driven by the vacuum pump 216, the steam in the outer shell 1 returns to the inner box 203 through the air inlet pipe 213, which makes it convenient to take out the tea leaves, reduces steam overflow, and realizes secondary heat recovery.

[0025] During operation, the handle 103 is pulled to open the opening and closing plate 101, and the tea leaves are placed in the inner cylinder 105. When all the tea leaves are placed, the handle 103 is pushed, and the opening and closing plate 101 rotates and closes with the outer shell 1 through the connecting shaft 104. At the same time, the return rubber ring 102 drives the opening and closing plate 101 to fit along the inner wall of the outer shell 1 to increase the sealing and prevent steam from leaking during the fixing process. Then, the circular sealing cover 206 is loosened, and water is poured into the inner box 203 through the water inlet pipe 205, and the circular sealing cover 206 is tightened.

[0026] When all preparations are completed, the electromagnetic heating coil 204 starts to emit heat through the control of the operation panel 201 and the drive of the battery pack 209, heating the water source to generate steam. At the same time, the steam temperature is detected by the temperature sensor 202 and then reflected on the operation panel 201. When the appropriate temperature is reached, the first telescopic valve 211 is opened through the control of the first electromagnetic control valve 212, and the steam enters the outer shell 1 through the outlet pipe 210. During this process, the rotating column 106 drives the inner cylinder 105 to rotate through the drive of the motor 107. At the same time, the steam enters the inner cylinder 105 through the air holes on the inner cylinder 105, thereby evenly heating the tea leaves.

[0027] When the tea leaves are finished withering, the battery pack 209 is turned off, the heating and steam generation are stopped, the first telescopic valve 211 is closed, and then the second telescopic valve 214 is opened by the control of the second electromagnetic control valve 215. At the same time, the steam in the outer shell 1 is driven by the air pump 216 to return to the inner box 203 through the air inlet pipe 213, making it easier to take out the tea leaves, reducing steam overflow, and realizing secondary heat recovery.

[0028] When the interior of the inner box body 203 needs to be cleaned or repaired, the rectangular sealing cover 207 is opened. After the cleaning or repair is completed, the circular snap-on plate 208 drives the rectangular sealing cover 207 along the circular groove to fit and connect with the inner box body 203 and the outer box body 2.

[0029] Through the above steps, the tea leaves are placed in the inner cylinder 105 in the outer shell 1, and then water is poured into the inner box 203 in the outer box 2 for heating, so that the water generates steam to wither the tea leaves. During this process, the inner cylinder 105 drives the tea leaves to rotate. By adopting the electromagnetic superheated steam drum method, uniform heating can be achieved, avoiding the problem of local overheating or overcooling, which helps to maintain the quality and taste of the tea leaves. In addition, the heating speed is fast, which greatly shortens the withering time and helps to improve production efficiency, so as to solve the problem that most of the existing withering methods are to put new tea leaves into a hot pot. Since the temperature is uncontrollable, it may cause uneven withering of the tea leaves, causing the tea leaves to have a smoky smell, thereby affecting production efficiency.
