Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea processing drying device. Background Technology

[0002] Tea drying is an indispensable part of the tea-making process. Its main purpose is to reduce the moisture content of the tea leaves to prevent them from becoming moldy and deteriorating.

[0003] The existing tea drying method involves first placing the picked tea leaves into a heated boiler, and then constantly turning the tea leaves with a shovel to ensure that the surface of the heated boiler can heat the tea leaves evenly. Although this heating method can dry the tea leaves quickly, it requires constant turning during the heating process, and impurities such as leaf stems in the tea leaves cannot be screened out during this process.

[0004] To address the problem that existing equipment cannot screen out impurities during the tea drying process, a device is designed that can simultaneously remove impurities during the drying process to overcome this issue. Utility Model Content

[0005] To overcome the problem that existing equipment cannot screen out impurities during the tea drying process.

[0006] The technical solution of this utility model is as follows: a tea processing and drying device, including a hot air blower, an outer shell and an air outlet, as well as a baffle and a ventilation pipe. A ventilation pipe is fixedly installed on one side of the hot air blower, and an air outlet is fixedly connected to one end of the ventilation pipe. The outer shell is fixedly installed on the upper end of the air outlet. A baffle is fixedly installed on one side of the air outlet by a positioning pin. A screening mechanism is provided inside the outer shell, and a discharge mechanism is provided on one side of the outer shell.

[0007] Preferably, the screening mechanism can complete the screening while drying, and can screen out heavier impurities such as leaf stems from the picked tea leaves. The discharge mechanism can quickly discharge the tea leaves after screening, and leave the impurities in the air outlet during the discharge process.

[0008] Preferably, the screening mechanism includes a motor, a connecting rod, filter plate one, a support frame, filter plate two, a positioning plate, and a rotating ring. A motor is fixedly installed on one side of the outer casing, and a connecting rod is fixedly installed at the motor's output end. A support frame is located inside the outer casing, with filter plate one fixedly connected to one side. Filter plate two is fixedly installed on the support frame via a positioning plate. A rotating ring is fixedly installed on the inner wall of the outer casing, and the support frame rotates on the rotating ring. The positioning plate on filter plate two is installed on the support frame using bolts. After all filter plates two are installed, the cylinder consisting of the support frame and filter plates two is inserted into the outer casing. The notch on one side of filter plate one matches and engages with the protrusion at one end of the connecting rod. Tea leaves are poured into the cylinder consisting of the support frame and filter plates two. Then, filter plate three is connected to the other side of the support frame. The motor and hot air blower are started. The motor drives the connecting rod to rotate. During rotation, the protrusion on the support frame continuously turns the tea leaves. The hot air blown by the hot air blows dry the tea leaves and blows the lighter tea leaves to the top, leaving heavier impurities such as stems at the bottom.

[0009] Preferably, one end of the connecting rod is provided with a protrusion, and one side of the filter plate is provided with a notch that fits and engages with the protrusion of the connecting rod. A rubber ring is provided on the inner wall of the rotating ring. When the motor starts, the cylinder composed of the support frame and the filter plate rotates on the rotating ring. The rubber ring ensures that the cylinder composed of the support frame and the filter plate can be securely connected to the rotating ring.

[0010] Preferably, the inner wall of the support frame is provided with protrusions. When the motor drives the support frame to rotate, the protrusions on the support frame will turn the tea leaves over, thereby increasing the contact area with the hot air and thus improving the drying rate.

[0011] Preferably, the discharge mechanism includes a connecting pipe, an electronic valve, an air outlet 2, a filter plate 3, and a handle. The upper end of the ventilation pipe is fixedly connected to the connecting pipe, and the electronic valve is fixedly installed on the connecting pipe. The upper end of the connecting pipe is fixedly connected to the air outlet 2. The support frame is threadedly connected to the filter plate 3, and the filter plate 3 is fixedly connected to the side of the handle. After drying, the motor is turned off and the electronic valve is turned on. The hot air from the hot air blows through the ventilation pipe and the connecting pipe to the air outlet 2, thereby blowing the tea leaves located above to one side. Then, the handle is turned to open the filter plate 3, and the selected tea leaves are discharged. Impurities such as leaf stems remain in the air outlet 1. After the tea leaves are discharged, the positioning pin on the baffle is removed, and the hot air blower is turned on again. The impurities in the air outlet 1 can then be blown out, thus completing the removal of impurities.

[0012] As a preferred option, the second air outlet is fixedly installed on the upper side of the outer casing. When the hot air blower is started, the tea leaves located above are blown out by the airflow. Taking advantage of the principle that impurities such as leaf stems are heavier and have a smaller airflow area, they are separated from the tea leaves. After separation, the airflow blows out the screened tea leaves.

[0013] Preferably, the electronic valve is used to control the opening and closing of the connecting pipe passage. When screening tea leaves, the electronic valve is closed; when discharging tea leaves, the electronic valve is opened. When the electronic valve is closed, the tea leaves are dried by the hot air blown out by the hot air blower. When the electronic valve is open, the motor is turned off, and the airflow of the hot air blows out from the other side, thus discharging the tea leaves.

[0014] The beneficial effects of this utility model are:

[0015] 1. The screening mechanism can complete the screening while drying, and can remove heavier impurities such as leaf stems from the picked tea leaves. In addition, the device can automatically turn the leaves over, making the drying more uniform.

[0016] 2. The discharge mechanism can quickly discharge the tea leaves after screening, and leave impurities in the air outlet during the discharge process. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 - Figure 5This utility model provides an embodiment of a tea processing and drying device, which includes a hot air blower 1, an outer shell 2, and an air outlet 3. It also includes a baffle 4 and a ventilation pipe 5. The ventilation pipe 5 is fixedly installed on one side of the hot air blower 1, and one end of the ventilation pipe 5 is fixedly connected to the air outlet 3. The outer shell 2 is fixedly installed on the upper end of the air outlet 3. The baffle 4 is fixedly installed on one side of the air outlet 3 by a positioning pin. A screening mechanism is provided inside the outer shell 2, and a discharge mechanism is provided on one side of the outer shell 2.

[0025] Please see Figure 2 , Figure 4 and Figure 5 In this embodiment, the screening mechanism includes a motor 9, a connecting rod 10, a first filter plate 11, a support frame 12, a second filter plate 13, a positioning plate 14, and a rotating ring 17. The motor 9 is fixedly installed on one side of the outer casing 2, and the connecting rod 10 is fixedly installed at the output end of the motor 9. The support frame 12 is located inside the outer casing 2, and the first filter plate 11 is fixedly connected to one side of the support frame 12. The second filter plate 13 is fixedly installed on the support frame 12 via the positioning plate 14. The rotating ring 17 is fixedly installed on the inner wall of the outer casing 2, and the support frame 12 rotates on the rotating ring 17. One end of the connecting rod 10 has a protrusion, and one side of the first filter plate 11 has a notch that matches and engages with the protrusion of the connecting rod 10. A rubber ring is provided on the inner wall of the rotating ring 17, and a protrusion is provided on the inner wall of the support frame 12. When the motor 9 drives the support frame 12 to rotate, the protrusion on the support frame 12 flips the tea leaves. The positioning plate 14 on the second filter plate 13 is installed on the support frame 12 using bolts. After all the filter plates 13 are installed, insert the cylinder composed of the support frame 12 and the filter plates 13 into the outer shell 2. The notch on one side of the filter plate 11 matches and engages with the protrusion at one end of the connecting rod 10. Pour the tea leaves into the cylinder composed of the support frame 12 and the filter plates 13. Then connect the filter plate 15 to the other side of the support frame 12. Start the motor 9 and the hot air blower 1. The motor 9 drives the connecting rod 10 to rotate. During the rotation, the protrusion on the support frame 12 continuously turns the tea leaves. The hot air blown out by the hot air blower 1 dries the tea leaves and blows the lighter tea leaves to the top, leaving the heavier impurities such as stems at the bottom. When the motor 9 starts, the cylinder composed of the support frame 12 and the filter plates 13 rotates on the rotating ring 17. The rubber ring ensures that the cylinder composed of the support frame 12 and the filter plates 13 can be firmly connected to the rotating ring 17, turning the tea leaves over. This increases the contact area with the hot air, thereby improving the drying rate.

[0026] Please see Figure 1 and Figure 2In this embodiment, the discharge mechanism includes a connecting pipe 6, an electronic valve 7, a second air outlet 8, a third filter plate 15, and a handle 16. The upper end of the ventilation pipe 5 is fixedly connected to the connecting pipe 6, and the electronic valve 7 is fixedly installed on the connecting pipe 6. The upper end of the connecting pipe 6 is fixedly connected to the second air outlet 8. The third filter plate 15 is threadedly connected to one side of the support frame 12, and the handle 16 is fixedly connected to one side of the third filter plate 15. The second air outlet 8 is fixedly installed on the upper side of the outer casing 2. When the hot air blower 1 is started, the tea leaves located above are blown out by the airflow. The electronic valve 7 is used to control the opening and closing of the passage of the connecting pipe 6. When screening tea leaves, the electronic valve 7 is closed; when discharging tea leaves, the electronic valve 7 is opened. After drying is completed, the motor 9 is turned off, the electronic valve 7 is opened, and the hot air blower... The hot air from 1 flows through the ventilation pipe 5 and connecting pipe 6 to the air outlet 2 8, blowing the tea leaves above to one side. Then, the handle 16 is turned to open the filter plate 3 15, and the selected tea leaves are discharged. Impurities such as leaf stems remain in the air outlet 3. Utilizing the principle that the leaf stems and other impurities are heavier and have a smaller air-receiving area, they are separated from the tea leaves. After separation, the airflow blows out the selected tea leaves. When the electronic valve 7 is closed, the tea leaves are dried by the hot air blown out by the hot air blown out by the hot air blower 1. When the electronic valve 7 is open, the motor 9 is closed, and the airflow from the hot air blower 1 blows out from the other side, thus discharging the tea leaves. After the tea leaves are discharged, the positioning pin on the baffle 4 is removed, and the hot air blower 1 is restarted. The impurities in the air outlet 3 can then be blown out, thus completing the removal of impurities.

[0027] During use, the positioning plate 14 on the filter plate 13 is installed on the support frame 12 using bolts. The cylinder composed of the support frame 12 and the filter plate 13 is inserted into the outer shell 2. Tea leaves are poured into the cylinder composed of the support frame 12 and the filter plate 13. Then, the filter plate 15 is connected to the other side of the support frame 12. The motor 9 and the hot air blower 1 are started. During the rotation, the protrusions on the support frame 12 continuously turn the tea leaves. The hot air blown out by the hot air blower 1 dries the tea leaves and blows the lighter tea leaves to the top, leaving the heavier impurities such as stems at the bottom. After drying, the motor 9 is turned off and the electronic valve 7 is opened, thereby blowing the tea leaves at the top to one side. Then, the handle 16 is turned to open the filter plate 15, and the screened tea leaves are discharged. Impurities such as stems are left in the air outlet 3. After the tea leaves are discharged, the positioning pin on the baffle 4 is removed, and the hot air blower 1 is started again. The impurities in the air outlet 3 can then be blown out.

[0028] Through the above steps, the screening mechanism can complete the screening while drying, and can screen out heavier impurities such as leaf stems from the picked tea leaves. The device can also automatically turn the leaves over, making the drying more uniform. The discharge mechanism can quickly discharge the tea leaves after screening, and in the process of discharge, impurities are left in the air outlet 3.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
