Description

Technical Field

[0001] The utility model belongs to the technical field of tea stir-frying, and particularly relates to a tea stir-frying device for Pu-erh tea production. Background Art

[0002] Tea frying, also known as stir-frying tea, is a common process for making tea. By continuously stir-frying tea leaves at high temperatures, the moisture in the tea leaves is volatilized, and at the same time, the chemical components in the tea leaves are activated, improving the aroma and taste of the tea.

[0003] However, there are still certain defects in the current Pu-erh tea fixation machines on the market. For example, when using a Pu-erh tea fixation machine, since the Pu-erh tea leaves are not dry enough before fixation and there is too much moisture on the surface of the tea leaves, it affects the fixation effect of Pu-erh tea. At the same time, when stir-frying the tea leaves, the temperature of the tea leaves at the bottom is too high, resulting in over-fixation of Pu-erh tea and affecting the quality of Pu-erh tea.

Specific embodiments

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] As Figures 1 to 4 shown, a tea frying device for Pu-erh tea production in this embodiment includes a support frame 1. A placement table 2 is installed on the side of the support frame 1, and a cylinder body 3 is installed on the front of the support frame 1. A transmission shaft 4 is rotatably installed on a fixed axis at an eccentric position on the inner wall of the cylinder body 3. One end of the transmission shaft 4 extending outside the cylinder body 3 is installed with a transmission gear 5. Since there is a placement table 2, there is space to install power equipment such as a motor. Thus, power is output by the motor to drive the transmission gear 5 to rotate, and the transmission gear 5 drives the transmission shaft 4 to rotate. A plurality of frying frames 6 are installed on the outer surface of one end of the transmission shaft 4 located inside the cylinder body 3. The cross-section of the frying frame 6 is fan-shaped and the distance between the bottom surface of the frying frame 6 and the inner wall of the cylinder body 3 is not greater than 3 mm. Due to the limitation of the distance, the special-shaped roller 7 can come into contact with the tea leaves. Thus, combined with the movement of the special-shaped roller 7, the effect of kneading the tea leaves is achieved. A plurality of special-shaped rollers 7 are rotatably installed on the inner side surface of the frying frame 6. Raised portions are provided on the outer surface of the special-shaped roller 7. The provision of the raised portions can enhance the kneading effect of the special-shaped roller 7. Springs 8 are symmetrically installed at both ends of the side surface of the special-shaped roller 7. One end of the spring 8 away from the special-shaped roller 7 is connected to the inner side wall of the frying frame 6. Combined with Figure 3As can be seen, the protruding position of the special-shaped roller 7 faces the bottom end of the inner wall of the cylinder body 3. Therefore, the protruding position of the special-shaped roller 7 can be reset by the elastic force of the spring 8, ensuring that when the frying frame 6 swings within the range of 0° to 10°, the protrusion can correctly contact the tea leaves. An exhaust device 9 is installed at the top of the inner wall of the cylinder body 3. The setting of the exhaust device 9 ensures the air circulation inside the cylinder body 3, preventing the tea leaves from being contaminated with abnormal odors during frying or static withering. A humidifier 10 is installed on one side of the inner wall of the cylinder body 3 through a bracket. A temperature and humidity sensor 20 is installed on the side of the humidifier 10. A first linear guide rail 11 is installed on the side of the inner wall of the cylinder body 3 away from the humidifier 10. A second linear guide rail 12 is installed on the moving end of the first linear guide rail 11. A storage cylinder 13 is installed on the moving end of the second linear guide rail 12. A guiding plate 14 is installed at the top inside the storage cylinder 13. A conveying mechanism 15 is arranged inside the storage cylinder 13. The conveying mechanism 15 is composed of two groups of rollers and baffles placed between the two groups of rollers. Combining Figure 4 with the content shown, it can be seen that the rollers are arranged in such a way that there are six rollers in total, divided into two groups. The two rollers in each group are connected by belt drive. Thus, a motor can be installed to drive one of the rollers to provide power. Therefore, the tea leaves are guided by the rollers and sent out of the storage cylinder 13 leaf by leaf along the guiding of the baffle. And the first linear guide rail 11 and the second linear guide rail 12 are provided. Also refer to Figure 3 shown, the first linear guide rail 11 and the second linear guide rail 12 are arranged perpendicularly, enabling the storage cylinder 13 to move horizontally and vertically, so as to evenly lay the tea leaves on the drying plate 18. The top of the storage cylinder 13 is connected to an inclined input port 16. An opening adapted to the position of the input port 16 is provided on the outer wall of the cylinder body 3. A lead-out plate 17 is installed at the bottom of the storage cylinder 13. An opening adapted to the lead-out plate 17 is provided at the bottom of the storage cylinder 13. A drying plate 18 is installed on the inner wall of the cylinder body 3. The position of the drying plate 18 on the inner wall of the cylinder body 3 is located below the storage cylinder 13. The drying plate 18 is filled with heat storage material inside. The heat storage material can store and release heat, providing temperature for the statically withered tea leaves to promote the evaporation of the moisture in the tea leaves. An electric control device 19 is installed on the outer wall of the cylinder body 3. Two assembly grooves 22 with electric heaters 21 installed inside are symmetrically provided at the bottom of the inner wall of the cylinder body 3. The electric control device 19 is electrically connected to the electric heaters 21, the humidifier 10, the first linear guide rail 11, the second linear guide rail 12, and the temperature and humidity sensor 20.

[0019] The working principle of this embodiment is as follows. When stir-frying tea, the tea leaves are put into the interior of the cylinder 3, and the driving gear 5 is rotated by an external power device, driving the transmission shaft 4 to rotate, and then the action of the stir-frying frame 6 is driven to achieve the stir-frying of the tea leaves. Therefore, before stir-frying, the electric heater 21 needs to be started to control the temperature of frying. When stir-frying, when the rotation angle range of the stir-frying frame 6 is between 10° and 90°, the rotation of the stir-frying frame 6 lifts the tea leaves to achieve the stir-frying effect. When the rotation range of the stir-frying frame 6 is between 10° and 0°, at this time, after the stir-frying frame 6 rotates, the special-shaped roller 7 will contact the surface of the tea leaves to achieve the kneading of the tea leaves. As the special-shaped roller 7 rotates, it will compress the spring 8 on one side and stretch the spring 8 on the other side. Thus, under the action of the elastic force, the special-shaped roller 7 rotates in the direction opposite to the movement direction of the stir-frying frame 6 to knead the tea leaves. And during the frying process, the ventilation inside the cylinder 3 is maintained through the exhaust device 9, and through the monitoring of the temperature and humidity sensor, the humidity inside the cylinder 3 is maintained in a suitable range by the humidifier. Thus, while stir-frying the tea, the tea leaves to be de-enzymed can be put into the storage cylinder 13 through the input port 16, and the tea leaves are singly conveyed out through the conveying structure in the storage cylinder 13, and with the cooperation of the first linear guide rail 11 and the second linear guide rail 12, the tea leaves are laid on the drying plate 18 piece by piece. Due to the existence of the humidifier, the storage of heat in the drying plate 18, and the existence of the exhaust device 9, the tea leaves are in an environment of ventilation and stable temperature and humidity, which helps the tea leaves to stand and wither.

[0020] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
