[0002] The automatic stir-frying machine in tea processing is a kind of equipment used for stir-frying tea leaves. It can automatically carry out the stir-frying process, improve production efficiency and ensure the quality of tea leaves. This machine is usually used in tea processing factories or tea gardens to replace the traditional manual stir-frying method.

[0003] The working principle of the automatic stir frying machine usually includes the following steps:

[0004] Put the tea leaves in: put the freshly picked tea leaves into the tea frying chamber of the automatic tea frying machine.

[0005] Frying process: The automatic stir-frying machine controls heating, stirring, ventilation and other operations through set programs and parameters, so that the tea leaves are heated evenly and achieve the ideal stir-frying effect.

[0006] End of frying: Once frying is completed, the automatic stir-frying machine will stop operating or issue a prompt to notify the operator to take out the fried tea leaves.

[0007] Existing tea frying machines generally use a drum frying method. The drum has a large volume. During the rolling process, the tea leaves will be tumbled inside the drum. The structural advantages of this drum frying tea are large volume and uniform heating. However, during the rolling process of the tea leaves inside the drum, many tea leaves are squeezed to a large extent during the tumbling process, and the tea leaves are squeezed to cause more breakage. The more broken tea leaves are, the greater the selling quality will be. Therefore, those skilled in the art provide an automatic frying machine for tea processing to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] The present application embodiment discloses an automatic stir-frying machine for tea processing. Figure 1-4 An automatic stir-frying machine for tea processing comprises a heating furnace 1, a pot cover 6 and a soft pad 9. An electric lifting frame 2 and a stir-frying pan 3 are arranged above the heating furnace 1. The electric lifting frame 2 is located on one side of the stir-frying pan 3. A motor 4 is arranged above the electric lifting frame 2. A rotating assembly 5 is arranged at an output end of one side of the motor 4. A fixed platform 7 is arranged below the rotating assembly 5. A scraper 8 is arranged on the surface of the fixed platform 7. The scraper 8 is arranged in three groups at equal intervals. The soft pad 9 is arranged on one side surface of the scraper 8. One side outer wall of the soft pad 9 is in contact with the inner wall of the stir-frying pan 3. The pot cover 6 is sleeved on the rotating assembly 5 and is located above the stir-frying pan 3.

[0028] In this way, during the implementation process, when the worker wants to fry the tea leaves, the worker puts the tea leaves that have just been picked into the frying pan 3. The arc-shaped material of the frying pan 3 allows the tea leaves to fall in the middle. The worker controls the lifting and lowering of the electric lifting frame 2 to control the height of the motor 4. The motor 4 drives the rotating assembly 5, the pot cover 6, the fixed platform 7, the scraper 8 and the soft pad 9 to descend. The scraper 8 and the soft pad 9 will fit with the inner wall of the frying pan 3 during the descent process. The soft pad 9 protects the outer surface of the scraper 8. The motor 4 starts to drive the multiple scrapers 8 to rotate. The scrapers 8 will contact the tea leaves during the rotation process. The tea leaves follow the scrapers 8 to roll and fry inside the frying pan 3. This parallel rolling and frying method greatly reduces the frying curvature of the tea leaves, reduces the collision between the tea leaves, and increases the integrity of the tea leaves during the frying process.

[0029] When the pot cover 6 descends, it will fit with the frying pan 3, and a relatively sealed environment is formed between the frying pan 3 and the pot cover 6, which can keep the internal heat of the frying pan 3 for a longer time, improve the stability of the internal temperature of the frying pan 3, reduce the entry of dust during the tea frying process, and improve the quality of the tea.

[0030] Among them, a limit card block 61 is fixedly connected to the bottom of the pot cover 6, and a plurality of limit card blocks 61 are provided. A limit card slot 31 is provided above the frying pan 3. The number of the limit card slots 31 is the same as that of the limit card blocks 61, and the limit card block 61 is perpendicular to the top of the limit card slot 31;

[0031] During the process of fitting the outer wall of the pot cover 6 with the inner wall of the frying pan 3, the pot cover 6 does not rotate with the rotating component 5. The multiple limit blocks 61 under the pot cover 6 will be embedded in the inside of the limit slot 31, so that the fitting stability between the pot cover 6 and the frying pan 3 is increased, and the connection stability between the frying pan 3 and the pot cover 6 is increased.

[0032] Preferably, a spherical pressure relief valve 62 is fixedly connected to the top of the pot cover 6, and the bottom of the spherical pressure relief valve 62 is interconnected with the inside of the frying pan 3. The spherical pressure relief valve 62 is located above the frying pan 3. When the frying pan 3 and the pot cover 6 are sealed, the internal temperature of the frying pan 3 will increase the air pressure. When the air pressure increases to a certain level, the air pressure will push open the spherical pressure relief valve 62. The spherical pressure relief valve 62 is used to discharge the internal air pressure of the frying pan 3, so as to improve the safety between the frying pan 3 and the pot cover 6.

[0033] Specifically, the rotating assembly 5 includes a rotating rod 51 fixedly connected to the output end of one side of the motor 4, a sliding rod 52 is slidably arranged below the rotating rod 51, the lower part of the sliding rod 52 is fixedly connected to the fixed platform 7, a return spring 53 is arranged inside the sliding rod 52, and the upper part of the return spring 53 is in contact with the lower part of the sliding rod 52;

[0034] The outer wall of the rotating rod 51 is a polygonal structure. The outer wall of the rotating rod 51 is slidably engaged with the inner wall of the sliding rod 52, so that the rotating rod 51 and the sliding rod 52 rotate with the motor 4. The pot cover 6 is located on the surface of the rotating rod 51. When the rotating rod 51 is pressed down, the return spring 53 is squeezed, so that there is a certain travel distance between the rotating rod 51 and the sliding rod 52. When the scraper 8 and the soft pad 9 are in contact with the inner wall of the frying pan 3 for frying, a certain margin is left in the sliding distance between the rotating rod 51 and the sliding rod 52, so that the scraper 8 is not easy to break the frying pan 3.

[0035] More specifically, a limiting slider 511 is fixedly connected to the lower part of the rotating rod 51, and a limiting slot 521 is provided inside the sliding rod 52. The limiting slider 511 is located inside the limiting slot 521 and slides against the inner wall of the sliding rod 52. The limiting slider 511 is used to limit the sliding distance of the rotating rod 51 inside the sliding rod 52, thereby improving the limiting effect of the sliding rod 52 on the rotating rod 51 and improving the sliding stability of the rotating rod 51 inside the sliding rod 52.

[0036] Furthermore, during the implementation process, the scraper 8 is set in a semi-arc shape, and the soft pad 9 is detachable and tightly attached to the outer wall surface of the scraper 8. The soft pad 9 is made of a high temperature resistant material with a certain plastic effect. The scraper 8 is made of a hard material. The outer surface of the scraper 8 is protected by the soft pad 9 to reduce wear. The soft pad 9 reduces the gap between the scraper 8 and the frying pan 3, so that the scraper 8 is located inside the frying pan 3 to push the tea leaves better and improve the frying efficiency.

[0037] The implementation principle of an automatic stir-frying machine in tea processing in an embodiment of the present application is as follows: when a worker wants to stir-fry tea leaves during use, the worker puts the freshly picked tea leaves into the stir-frying pan 3. The arc-shaped material of the stir-frying pan 3 allows the tea leaves to fall in the middle. The worker controls the lifting and lowering of the electric lifting frame 2 to control the height of the motor 4. The motor 4 drives the rotating assembly 5, the pot cover 6, the fixed platform 7, the scraper 8 and the soft pad 9 to descend. The scraper 8 and the soft pad 9 will fit with the inner wall of the stir-frying pan 3 during the descent process. The soft pad 9 protects the outer surface of the scraper 8. The motor 4 starts to drive multiple scrapers 8 to rotate. The scraper 8 will contact the tea leaves during the rotation process. The tea leaves follow the scraper 8 to roll and stir-fry inside the stir-frying pan 3. This parallel rolling and stir-frying method greatly reduces the stir-frying curvature of the tea leaves, reduces the collision between the tea leaves, and increases the integrity of the tea leaves during the frying process.
