Description

Technical Field

[0001] This utility model relates to the field of tea machinery and equipment, and in particular to a photothermal intelligent shaking machine for Da Hong Pao tea. Background Technology

[0002] In the production process of Da Hong Pao tea, shaking is a crucial step. Its purpose is to break down the cell structure at the leaf edges, softening the leaves under the action of polyphenol oxidase, causing the leaf edges to turn red, and inducing the volatilization of aromatic substances to achieve the characteristic "green leaves with red edges and floral fragrance." Production practice shows that polyphenol oxidase is more effectively activated in a shaking environment with suitable light, temperature, and humidity, which is beneficial for the formation of Da Hong Pao tea's superior quality and flavor. However, existing shaking devices rely solely on blowing hot air, with a blower continuously pumping hot air into the shaking machine. The shaking effect depends entirely on the operator's experience, lacking visual temperature and humidity control. Therefore, it demands exceptionally high tea-making skills from the operators, and also increases production costs. Summary of the Invention

[0003] The purpose of this invention is to provide a photothermal intelligent shaking machine for Da Hong Pao tea, which solves the problem that the temperature and humidity control and regulation of existing shaking machines are inconvenient and affect the shaking quality.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a photothermal intelligent shaking machine for Da Hong Pao tea, including a weighing conveyor, a frame, a shaking drum, a drive device, infrared electric heating lamps and spotlights, a blower, a temperature sensor, a humidity sensor, a timing device, a control display screen and other components.

[0005] To achieve quantitative feeding and conveying for impurity removal, the screen conveyor belt is set at an angle so that insect eggs, mud, sand, dust and other impurities carried in the tea leaves can be removed by sieving through the screen. A weighing conveyor trough is also configured at the feed end of the screen conveyor belt to carry out integrated weighing and impurity removal by tilting the conveyor belt, and send the clean buds and leaves into the shaking drum for quantitative light and heat shaking.

[0006] To achieve uniform light and heat shaking and automatic material turning, infrared electric heating tubes and infrared bulbs are respectively installed at the feed inlet, central shaft, and discharge end of the drum. A set of leaf-turning claws is also installed on the central shaft to turn the buds and leaves for light-transmitting shaking, ensuring uniform shaking. To prevent damage to the infrared electric heating tubes and infrared bulbs, a quartz cover is wrapped around them to ensure normal light emission and heat generation.

[0007] To achieve efficient light and heat shaking, the inner wall of the shaking drum is made of bamboo strips, while the outer wall is made of laser-microporous stainless steel. This allows for efficient shaking by utilizing the "shaking cage" of the bamboo inner wall to disrupt the cell structure of the leaf margins, while also allowing the laser-microporous stainless steel outer wall to dissipate moisture. In particular, it solves the technical problem that the drum is prone to deformation due to light and heat at high temperatures.

[0008] In order to regulate the light and heat shaking environment in a timely manner and promote intelligent light and heat shaking of tea buds and leaves with controlled temperature and humidity, wind speed sensors, temperature sensors, and humidity sensors are also installed in the shaking drum. The technical parameters such as shaking temperature, shaking humidity, dehumidification air volume, and shaking time can be set by adjusting the display screen.

[0009] The beneficial effects of this invention are as follows: By installing infrared electric heating lamps and illumination lamps inside the shaking drum, this invention achieves photothermal shaking, thereby improving the quality of the shaking process. Simultaneously, by combining various sensors to control the temperature and humidity inside the shaking drum, intelligent shaking is achieved, and the shaking time can be precisely controlled, enabling automated control. A weighing conveyor is installed at the feeding end of the shaking drum to weigh and remove impurities from the tea leaves, ensuring consistent weight for each shaking cycle and facilitating the setting of various shaking parameters. Furthermore, the cleaned tea leaves effectively prevent unpleasant odors emitted during shaking from foreign objects from affecting the aroma of the tea.

[0010] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0015] Examples, such as Figures 1 to 4 As shown, a photothermal intelligent shaking machine for Da Hong Pao tea includes a weighing conveyor 12, a frame 1, a shaking drum 2 rotatably mounted on the frame 1, a drive device 13 that drives the shaking drum 2 to rotate, an infrared electric heating lamp 3 and a light lamp 4 installed inside the shaking drum 2, a temperature sensor 7, a humidity sensor 8, a control display screen 9, and a timing device 10.

[0016] The weighing conveyor 12 is arranged at the feed end 25 of the shaking drum 2, and feeds the tea leaves into the shaking drum 2. The weighing conveyor 12 includes a screen conveyor belt 121, which is a 10-12 mesh stainless steel screen conveyor belt. The screen conveyor belt 121 tilts upward at an angle of 30-32 degrees to convey the tea leaves. A vibrator 122 is installed below the screen conveyor belt 121. The screen conveyor belt 121 vibrates while conveying upward, using the stainless steel screen to remove impurities such as mud, dust, and insects from the tea leaves, and feeds the clean, dry buds into the shaking drum. The feed end of the screen conveyor belt 121 is provided with a weighing conveyor trough 123, and a weighing device 124 is provided at the bottom of the weighing conveyor trough 123. A weighing conveyor belt 125 is provided inside the weighing conveyor trough 123, and a feed hopper 126 is also provided above the weighing conveyor trough 123. The tea leaves on the feed hopper 126 fall onto the weighing conveyor belt 125. When the weighing device 124 obtains that the weight of the tea leaves on the weighing conveyor belt 125 reaches the set requirement, the feed hopper 126 stops discharging material, and then the weighing conveyor trough 123 rotates, and the tea leaves fall from the outlet of the weighing conveyor trough 123 onto the screen conveyor belt 121 below.

[0017] The shaking roller 2 is 2.8 meters long and 0.8 meters in diameter. One end of the shaking roller 2 is the feed end 25, and the other end is the discharge end 26. The shaking roller 2 has a two-layer structure: an inner layer of bamboo strips 21 and an outer layer of stainless steel material 22. The stainless steel material layer 22 has uniformly distributed laser micropores 221 with a 100-mesh aperture. The roller body, which uses bamboo strips and laser microporous stainless steel material, can not only utilize the "shaking cage" of the bamboo inner wall to destroy the cell structure of the leaf edge for efficient shaking, but also utilize the laser microporous stainless steel outer wall to dissipate the moisture of the green leaves. It can also solve the technical problem that the roller is easily deformed by light, heat and high temperature.

[0018] The shaking drum 2 is equipped with a central shaft 23, with both ends of the central shaft 23 fixedly supported on the frame 1. To ensure that the tea buds receive even sunlight, three finger-shaped leaf-turning claws 24 are installed at intervals on the central shaft to turn the buds and leaves for uniform light transmission during shaking. To facilitate smooth tea discharge from the shaking drum, the frame 1 includes a front support leg 101 and a rear support leg 102. An adjusting cylinder 103 is located at the middle of the front support leg 101 to adjust its height. The tilt angle of the shaking drum 2 can be adjusted by adjusting the cylinder 103, thereby facilitating the discharge of tea.

[0019] The drive device 13 includes a continuously variable speed motor 131, with a drive gear 132 at its output end. A driven gear 133 is mounted on the shaking drum 2. The continuously variable speed motor 131 drives the drive gear 132 to rotate, and the driven gear 133, in turn, drives the shaking drum 2 to rotate. The continuously variable speed motor 131 allows for easy speed adjustment to enable shaking at different speeds.

[0020] The infrared electric heating lamp 3 is a far-infrared carbon fiber electric heating lamp, embedded in the middle of the central shaft 23. The illumination lamp 4 is a GE infrared bulb, with two lamps installed on either side of the infrared electric heating lamp 3, one 50cm from the inlet and the other 60cm from the outlet, forming a three-dimensional light and heat space to provide light and heat for the tea leaves during the light-heat shaking process. To prevent damage to the bulbs of the infrared electric heating lamp 3 and illumination lamp 4 from impacts, a quartz cover 14 is wrapped around them for protection, ensuring normal light and heat generation. To facilitate adjustment of the functions of the infrared electric heating lamp 3 and illumination lamp 4, thereby achieving different temperatures and light intensities, an adjustment switch 5 is connected to the infrared electric heating lamp 3 and illumination lamp 4 to adjust their power, adapting to the different light intensities and temperatures required for shaking various buds and leaves.

[0021] To promptly remove the hot and humid air from the shaking drum 2, a blower 6 is installed at the feed end 25 to blow air into the shaking drum 2. The blower 6 is a frequency converter type, with its flared outlet installed 15-20 cm below the feed inlet below the central axis 23 of the shaking drum 2. It blows air into the shaking drum 2 at a flow rate of 100-125 cubic meters per minute, both to dissipate heat from the buds and leaves and to remove the dampness generated during the light and heat shaking process. A wind speed sensor 11 is also installed in the center of the flared outlet. Its function is to detect the wind speed and transmit the detected wind speed signal to the control display screen 9, which then adjusts the airflow by controlling the fan speed.

[0022] The temperature sensor 7 is an STT-R type temperature sensor, which is installed in the middle of the shaking drum and connected to the control display screen 9 to adjust the temperature inside the shaking drum and provide a suitable shaking temperature for the buds and leaves.

[0023] The humidity sensor 8 is an MH-8823L type humidity sensor, which is installed in the middle of the shaking drum, corresponding to the temperature sensor, and connected to the control display screen 9 to adjust the humidity inside the shaking drum and provide suitable humidity for the shaking buds and leaves.

[0024] The timing device 10 is an OHR-B200-AX / 1 / X / XA type intelligent digital display timer. This timer has timing and alarm functions. It can set and increase or decrease the photothermal shaking time. Once the set photothermal shaking time is completed, the alarm will emit sound and light to facilitate the timed shaking operation.

[0025] The control display screen 9 is an LED display screen controller, which is connected to the weighing device 124, the drive device 13, the wind speed sensor 11, the temperature sensor 7, the humidity sensor 8, and the timer 10. It sets technical parameters such as the weight of the tea leaves, the rotation speed of the shaking drum, the shaking time, the temperature, humidity, and dehumidification air volume inside the shaking drum, so as to carry out intelligent photothermal shaking. It is also used to receive signals from the temperature sensor 7, the humidity sensor 8, and the wind speed sensor 11 to control the operation of the adjustment switch 5 and the blower 6.

[0026] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
