Description

Technical Field

[0001] This utility model relates to the field of tea production technology, and in particular to a tea stir-frying machine. Background Technology

[0002] Tea leaves typically contain high levels of moisture after picking. If this moisture is not removed promptly, it can easily lead to spoilage and mold, affecting the quality and shelf life of the tea. The high temperature during the tea-frying process can quickly evaporate the moisture in the tea leaves, reducing the moisture content to a suitable range, generally around 3% to 5%, which is beneficial for the long-term preservation of the tea.

[0003] The prior art discloses a tea stir-frying machine, including a wok and a fixed ring. The left and right ends of the fixed ring are fixedly connected to a bracket. A heating plate is installed inside the bottom side of the wok. The top of the wok is rotatably connected to the bottom of the fixed ring. A drive mechanism for driving the wok to rotate is installed on the bracket. The bottom of the wok is provided with a discharge port. A sealing plug is inserted into the discharge port. A conical column is fixedly connected to the bottom of the sealing plug. Two limiting holes are provided on the conical column. Limiting rods are slidably installed inside the two limiting holes. The two limiting rods are fixedly installed at the bottom of the wok. A sealing plate is fixedly connected to the top of the fixed ring by screws. Four electric cylinders are fixedly connected to the top of the sealing plate.

[0004] When the above device is working, the tea leaves enter the gap between the wok and the stirring plate. After being heated and dehydrated, the tea leaves are brittle and easily break when squeezed.

[0005] Therefore, it is necessary to provide a tea stir-frying machine to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0026] First embodiment:

[0027] like Figure 1-6 As shown, the tea stir-frying machine provided by this utility model includes: a support 101, which can be supported by welding square tubing to support parts mounted thereon. Four supports 102 are provided on the upper end of the support 101, located at the four corners of the support 101. A first rotating shaft 104 is rotatably mounted on two supports 102 on the same side. One end of the first rotating shaft 104 is connected to a first motor 103. A drive wheel 105 is mounted around the first rotating shaft 104. The first rotating shaft 104 is a transmission shaft. After the first motor 103 drives the first rotating shaft 104 to rotate, the first rotating shaft 104... The drive wheel 105 rotates, and a stir-frying assembly is placed on the drive wheel 105. The stir-frying assembly includes a drum mesh 106, which is a cylindrical metal mesh with several holes on its surface. Annular tracks 107 are provided at both ends of the drum mesh 106, and a groove is provided in the middle of the annular track 107. The groove width is adapted to the drive wheel 105. Both the drive wheel 105 and the annular track 107 are made of iron, and the surface of the drive wheel is rough. The entire stir-frying assembly is supported by four drive wheels 105. Several stir-frying plates 111 are fixedly installed along the axial direction on the inner wall of the annular track 107. The shape of the stir-frying plates 111 is as follows: Figure 6As shown, a second rotating shaft 109 is rotatably mounted on the support 101. The second rotating shaft 109 passes through the drum mesh 106 and has several buffer plates 110 mounted on it. One end of the second rotating shaft 109 is connected to a second motor 108, which drives the second rotating shaft 109 to rotate. The second rotating shaft 109 then drives the buffer plates 110 to rotate. A heat-insulating shell 201 is mounted on the upper end of the support 101. The heat-insulating shell 201 is a C-shaped shell with openings at both ends and the bottom. The heat-insulating shell 201 covers the drum mesh 106, and the heating wire inside the heat-insulating shell 201 is located at the top of the shell. In use, fresh tea leaves are first placed into the drum mesh 106 through the openings of the drive wheels 105 at both ends. Then, the first motor 103 and the second motor 108 are started respectively. The first motor 103 drives the first rotating shaft 104 to rotate, and then the first rotating shaft 104 drives the drive wheel 105 to rotate. The drive wheel 105 drives the tea leaves on it to rotate. The circular track 107 and the drum mesh 106 rotate. Finally, the fresh tea leaves are tumbled and tossed by the stirring plate 111 inside the drum mesh 106. The second motor 108 rotates, driving the second rotating shaft 109 to rotate. Finally, the second rotating shaft 109 drives the buffer plate 110 to rotate. The rotation speed of the drum mesh 106 is in the same direction as the rotation of the second rotating shaft 109 and the buffer plate 110, but the rotation speed is different. The rotation speed of the second rotating shaft 109 and the buffer plate 110 is slower. When the tea leaves fall from the stirring plate 111, they will fall onto the buffer plate 110 located at the lower end of the stirring plate 111. Because the rotation speed of the buffer plate 110 is slower, the tea leaves that are tumbled down are received by multiple stirring plates 111 and separated into multiple portions. As the buffer plate 110 rotates, the tea leaves on it fall downwards and fall back onto the drum mesh 106. This cycle repeats. After the heating wire is energized, the temperature inside the heat preservation shell 201 continuously rises. The fresh tea leaves are tumbled and heated at the same time, evaporating the moisture in them.

[0028] By setting a buffer plate 110 as an intermediate platform when the tea leaves are tossed and fall, the impact speed when the tea leaves come into contact with the device is reduced. At the same time, the rotation of multiple buffer plates 110 and the stirring plate 111 divides the fresh tea leaves in the drum mesh 106 into several parts for stirring, reducing the stacking of tea leaves and helping to maintain the integrity of the tea leaves.

[0029] Second embodiment:

[0030] like Figure 1 As shown, a fan 113 is provided on the bracket 101. The fan 113 is located at one end of the roller mesh 106. When the fan 113 is started, it pushes the air to flow, so the air in the roller mesh 106 can be drawn out by the fan 113.

[0031] Fresh tea leaves contain a high moisture content. As the moisture evaporates into the air, the water vapor in the drum screen 106 can be discharged along with the air by setting up the fan 113.

[0032] Third embodiment:

[0033] As shown in the figure, a circular ring is provided inside the circular track 107. The circular ring has a certain height. When tea is fried, it is tumbled and tossed in the drum mesh 106. Its movement trajectory is irregular. By setting the circular ring, the tea can be prevented from spilling out from the openings at both ends of the drum mesh 106.

[0034] Fourth embodiment:

[0035] like Figure 4 As shown, the roller screen 106 is provided with a discharge port 114, and a sealing door with the same curvature as the roller screen 106 is provided at the discharge port 114. The sealing door is provided with a locking component, such as bolts, to fix the sealing door to the discharge port 114. The lower end of the roller screen 106 is provided with a collection port 115, and the shape of the collection port 115 is as shown. Figure 4 As shown, the collection port 115 has openings at both the top and bottom, with the top opening being larger and the bottom opening being smaller. After the tea leaves are fried, the sealing door is opened, and the tea leaves fall from the sealing door into the collection port 115 during the turning process, and leave the device through the opening at the bottom of the collection port 115. A container can be placed at the bottom of the collection port 115 beforehand to hold the tea leaves.

[0036] By setting the discharge port 114, the tea leaves that have been roasted are automatically discharged.

[0037] Fifth embodiment:

[0038] like Figure 6 As shown, a baffle 112 is provided at the end of the stir-frying plate 111. The baffle 112 is perpendicular to the stir-frying plate 111. When tea leaves fall onto the baffle 112, which is in a horizontal position, during the stir-frying process, the tea leaves rotate together with the baffle 112. As the baffle 112 rotates and tilts to a vertical position, the tea leaves first slide down on the baffle 112 and then fall onto the baffle 112. Due to the blocking effect of the baffle 112, the tea leaves stay on the baffle 112 for a longer period of time. This helps the tea leaves to be more evenly sprinkled on the drum screen 106 and evenly distributed by the stir-frying plate 111 on the drum screen 106.

[0039] Working principle: Fresh tea leaves are tumbled and tossed by the stirring plates 111 inside the drum mesh 106. The second motor 108 rotates, driving the second rotating shaft 109 to rotate. Finally, the second rotating shaft 109 drives the buffer plate 110 to rotate. The rotation speed of the drum mesh 106 is in the same direction as the rotation of the second rotating shaft 109 and the buffer plate 110, but at different speeds. The rotation speed of the second rotating shaft 109 and the buffer plate 110 is slower. When the tea leaves fall from the stirring plates 111, they will fall onto the buffer plate 110 located at the lower end of the stirring plates 111. Because the rotation speed of the buffer plate 110 is slower, the tea leaves that are tumbled down are caught by multiple stirring plates 111 and separated into multiple portions. As the buffer plate 110 rotates, the tea leaves on it fall downwards and fall back onto the drum mesh 106.

[0040] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
