Description

Technical Field

[0001] This utility model relates to the field of tea roasting technology, specifically a tea roasting stirring device. Background Technology

[0002] Roasting tea is a method of processing tea leaves by heating, primarily used for black tea, dark tea, and oolong tea. The roasting process mainly includes spreading out the tea leaves, turning them over, and heating. Spreading out the tea leaves involves laying them flat on a bamboo mat to allow them to cool naturally. Turning them over is done manually or mechanically to ensure even heating. Heating involves using charcoal or electric heating equipment to gradually reduce the moisture content of the tea leaves, thereby enhancing their aroma and flavor.

[0003] In the prior art, patent publication number CN209185602U discloses a tea roasting machine, including a main body, a heating device disposed within the main body, a roasting rack, and a sieve tray placed on the roasting rack. The main body has a movable frame, the bottom of which is equipped with casters. The roasting rack is disposed within the movable frame, and the movable frame is equipped with a drive device for rotating the roasting rack.

[0004] The above-mentioned roasting machine has some problems in actual use. For example, after the tea has been roasted for a specified time, it needs to be turned over. If the above-mentioned roasting machine is used, after the roasting machine has been roasting for a period of time, it is necessary to open the door and manually turn over the tea on the rack. At this time, the temperature inside the roasting machine is high, making it difficult to turn over. Improper operation can easily burn the operator. Therefore, we propose a tea roasting turning device. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This embodiment provides a technical solution: a tea roasting and turning device, including a roasting box 1 and a turning mechanism 3;

[0025] Baking oven 1: It has an internal rack 2, with a storage basket 5 placed on the upper surface of the middle shelf of the rack 2. A controller 6 is located on the front of the baking oven 1, with its input connected to an external power source. Evenly distributed air inlet pipes 7 are located on the lower right side of the baking oven 1, and an air outlet pipe 8 is located on the upper side. The right end of the air inlet pipes 7 is connected to an external air supply device, and the upper end of the air outlet pipe 8 is connected to an external suction device. Heating tubes 9 are located on the left and right sides of the baking oven 1, and a temperature sensor 10 is located on the left side of the baking oven 1. The side section of the temperature sensor 10 extends into the interior of the baking oven 1. The input end of the heating tube 9 is electrically connected to the output end of the controller 6. The temperature sensor 10 and the controller 6 are bidirectionally electrically connected. The front of the baking oven 1 is hinged with a door 11. When the stir-frying device is needed, the tea leaves to be roasted can be placed on the storage basket 5 and spread out. Then, the door 11 can be opened, and the storage basket 5 can be placed on the rack 2 in sequence. Then, the controller 6, the heating tube 9 and the temperature sensor 10 can be activated, and current flows through the interior of the heating tube 9. The resistance wire generates heat, which is then conducted through the air to continuously heat the tea leaves. At this time, the temperature sensor 10 operates. When the temperature rises, the two different metals inside the temperature sensor 10 come into contact with each other, and a thermoelectric potential difference will be generated at the contact part. As the temperature changes, the thermoelectric potential difference will also change. Based on this change, the temperature of the object being measured can be calculated. The temperature sensor 10 returns the resistance information to the inside of the controller 6. The temperature sensor 10 returns the resistance information to the inside of the controller 6 to measure the temperature inside the baking oven 1 in real time, so that the internal temperature is maintained between 100℃ and 110℃ and heated continuously for half an hour. At the same time, the external air supply device supplies cold air to the baking oven 1 through the air inlet pipe 7, and the external air suction device draws out the hot steam generated by baking through the air outlet pipe 8. The storage basket 5 is a metal wire woven basket with a breathable effect. There are holes on the lower surface of each layer of the storage rack 2. The cold air passes through the holes and the storage basket 5 from bottom to top, and steam is generated when the tea leaves are heated. The steam gradually flows upward with the cold air from bottom to top and is finally drawn out by the air outlet pipe 8.

[0026] The material turning mechanism 3 includes a handle 31, a turning frame 32, rotating cylinders 35, and rubber dials 39. The handle 31 is located on the outside of the baking oven 1. The turning frame 32 is located on the right side of the handle 31. The turning frame 32 has evenly distributed rotating cylinders 35 inside. The leftmost rotating cylinder 35 is rotatably connected to the left side wall of the turning frame 32, and the rightmost rotating cylinder 35 is rotatably connected to the right side wall of the turning frame 32. There are twenty rotating cylinders 35, and every two horizontally adjacent rotating cylinders 35 are rotatably connected. The outer arc surface of the rotating cylinders 35 is fixedly connected with evenly distributed rubber dials 39. From left to right, the opening direction of the rubber dials 39 on the outer surface of the odd-numbered rotating cylinders 35 is backward, and the opening direction of the rubber dials 39 on the outer surface of the even-numbered rotating cylinders 35 is backward. The opening of the rubber tweezers 39 faces forward, and there is a gap between every two horizontally adjacent rubber tweezers 39. The turning mechanism 3 includes a rotating rod 33, a sealing cylinder 34, a gear ring 36, a first gear 37, and a second gear 38. The rotating rods 33 are symmetrically connected to the left and right inner walls of the turning frame 32. The outer arc surfaces of the two rotating rods 33 are respectively fixedly connected to evenly distributed first gears 37. The inner arc surfaces of the rotating cylinder 35 are respectively fixedly connected to gear rings 36. The gear rings 36 mesh with the first gears 37 corresponding to the vertical position. The row of first gears 37 on the front side and the row of first gears 37 on the rear side are staggered. The right side of the turning frame 32 is provided with a sealing cylinder 34. The right ends of the two rotating rods 33 are respectively fixedly connected to second gears 38. The second gears 38 are all located inside the sealed cylinder 34, and the two second gears 38 are meshed together. A motor 4 is located on the right side inside the handle 31. The output shaft of the motor 4 is fixedly connected to the left end of the rear rotating rod 33. The input end of the motor 4 is electrically connected to the output end of the controller 6. Heating can then be stopped, and the cabinet door 11 can be opened. The controller 6 can then be adjusted, and the motor 4 will operate. The output shaft of the motor 4 will rotate, thereby driving the rear rotating rod 33 to rotate. This, in turn, drives the front rotating rod 33 to rotate in the opposite direction via the two second gears 38. At this time, the rotation direction of the front row of first gears 37 is opposite to that of the rear row of first gears 37. The meshing effect of 37 and toothed ring 36 causes the rotation direction of each pair of horizontally adjacent rotating drums 35 to be opposite. At this time, you can manually pick up handle 31 and extend the turning rack 32 into the upper side of the storage basket 5. Then, manually move the turning rack 32 from left to right. At this time, the rotating drum 35 will drive the rubber dial 39 to rotate. At this time, each pair of horizontally adjacent rubber dials 39 will turn the half-roasted tea leaves. After the tea leaves are turned by the rubber dials 39, they will not fly to either side, but will pass through the gaps between the rubber dials 39 and be turned over. Then, you can turn over the tea leaves in multiple sets of storage baskets 5 to complete the stir-frying. At this time, you can close the box door 11. After another half hour of roasting, the tea roasting operation will be completed.

[0027] The working principle of the tea roasting stirring device provided by this utility model is as follows: When the stirring device is needed, the tea to be roasted can be placed on the storage basket 5 and spread out. Then, the box door 11 can be opened, and the storage basket 5 can be placed on the storage rack 2 in sequence. Then, the controller 6, heating tube 9 and temperature sensor 10 can be activated. Current flows through the resistance wire inside the heating tube 9 to generate heat, which is then conducted through the air to continuously heat the tea. At this time, the temperature sensor 10 is activated. When the temperature rises, when the two different metals inside the temperature sensor 10 come into contact with each other, a thermoelectric potential difference will be generated at the contact part. As the temperature changes, the thermoelectric potential difference will also change. Based on this change, the temperature of the measured object can be calculated. The temperature sensor 10 returns the resistance information to the controller 6 to measure the temperature inside the roasting box 1 in real time, so that the internal temperature is maintained between 100℃ and 110℃ and heated continuously for half an hour. At the same time, the external air supply device supplies cold air to the roasting box 1 through the air inlet pipe 7, and the external air suction device sucks out the hot steam generated by roasting through the air outlet pipe 8. At this time, heating can be stopped. Open the box door 11, then control the controller 6, and the motor 4 will start running. The output shaft of the motor 4 will rotate, which will drive the rear rotating rod 33 to rotate. This, in turn, will drive the front rotating rod 33 to rotate in the opposite direction through the two second gears 38. At this time, the rotation direction of the front row of first gears 37 is opposite to that of the rear row of first gears 37. Due to the meshing effect of the first gears 37 and the gear ring 36, the rotation direction of each pair of horizontally adjacent rotating drums 35 will be opposite. At this time, you can manually pick up the handle 31 and extend the tipping rack 32 into the box. On the upper side of the storage basket 5, manually move the turning rack 32 from left to right. At this time, the rotating drum 35 will drive the rubber dial 39 to rotate. At this time, every two horizontally adjacent rubber dials 39 will turn half of the roasted tea leaves. After the tea leaves are turned by the rubber dials 39, they will not fly to any side, but will pass through the gaps between the rubber dials 39 and be turned over. Then the tea leaves inside multiple sets of storage baskets 5 can be turned over to complete the stir-frying. At this time, the box door 11 can be closed. After another half hour of roasting, the tea roasting operation will be completed.

[0028] It is worth noting that the core chip of the controller 6 disclosed in the above embodiments is a PLC microcontroller, specifically the STM32. The motor 4, heating tube 9, and temperature sensor 10 can be freely configured according to the actual application scenario. It is recommended that the motor 4 be a 42CM02-1A stepper motor, the heating tube 9 be a conventional stainless steel dry-burning heating tube, and the temperature sensor 10 be a PT-100 temperature sensor. The controller 6 controls the operation of the motor 4, heating tube 9, and temperature sensor 10 using methods commonly used in the prior art.
