Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a continuous cooling conveyor line for tea processing. Background Technology

[0002] In the traditional tea production and processing industry, the general production process for tea varieties that require rolling is as follows: withering, fixation, rolling, drying and packaging. In the fixation process, the roasted tea leaves are transported to the rolling process by a transport device. The temperature of the tea leaves after fixation is very high and needs to be cooled quickly, which requires the use of a cooling conveyor device.

[0003] Currently, the cooling method for tea leaves after processing mostly involves spreading the tea leaves directly on a conveyor and using a fan to cool them. However, this method is inefficient and does not effectively cool the tea leaves at the bottom. Therefore, we urgently need a continuous cooling conveyor line for tea processing. Utility Model Content

[0004] This utility model provides a continuous cooling conveyor line for tea processing, which can solve the problem that in the existing technology, the cooling method after tea is fixed is mostly to spread the tea directly on the conveyor and use a fan to blow air to cool it. The fan blowing cooling method is inefficient and does not have a good cooling effect on the tea at the bottom.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a continuous cooling conveyor line for tea processing, comprising a support frame and a conveyor belt, wherein a cooling mechanism is provided on the outside of the support frame and a cleaning mechanism is provided on the inside of the support frame;

[0006] The cooling mechanism includes a feeding frame, an air-cooled shell, and a water-cooled frame. Multiple inclined plates are fixedly connected inside the feeding frame. A through hole is opened at the top of each inclined plate. Cooling branch pipes are installed inside the inclined plates. One end of each cooling branch pipe is fixedly connected to a main cooling pipe. The bottom of the main cooling pipe is fixedly connected to an air outlet. A spiral cooling pipe is installed inside the water-cooled frame. A circulating pump is installed at one end of each spiral cooling pipe, and a heat exchanger is flanged to the other end of each spiral cooling pipe. A water tank is installed at one end of the heat exchanger.

[0007] Preferably, the feed frame and the air-cooled shell are both fixedly connected to the top of the support frame, and the water-cooled frame is fixedly connected to the inside of the support frame.

[0008] Preferably, one end of the cooling main pipe is connected to a fan, and one end of the cooling main pipe penetrates through the air-cooled shell and extends into the interior of the air-cooled shell.

[0009] Preferably, the cooling branch pipe is configured as a forked branch pipe, and an air outlet is provided on the outside of the cooling branch pipe.

[0010] Preferably, multiple air outlet hoppers are provided, and the multiple air outlet hoppers are arranged in a linear array.

[0011] Preferably, the outer wall of the spiral cooling pipe is in contact with the outer wall of the conveyor belt, and both ends of the spiral cooling pipe penetrate the water-cooling frame and extend to the outside of the support frame.

[0012] Preferably, a dehumidifier is provided on the outside of the air-cooled shell, and a dehumidification pipe is installed at one end of the dehumidifier.

[0013] Preferably, the cleaning mechanism includes a cleaning frame, a rotating roller is rotatably connected to the inner side of the cleaning frame, and a cleaning brush is installed on the outer side of the rotating roller.

[0014] Preferably, the cleaning frame is fixedly connected to the inner side of the support frame, and one end of the cleaning brush is attached to one end of the conveyor belt.

[0015] Preferably, a motor is mounted on one end of the rotating roller, and one end of the motor is fixedly connected to one end of the support frame.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] I. This utility model involves feeding tea leaves into a feed frame. Multiple inclined plates within the feed frame, arranged in a staggered pattern, slow the falling speed of the tea leaves. Simultaneously, a fan is activated, directing air from the cooling branch pipes to the interior of the inclined plates. The air is then blown out through external vents and through through-holes at the top of the inclined plates, allowing the air to directly cool the tea leaves and reduce their weight as they fall onto the inclined plates, preventing breakage. The tea leaves then slowly fall onto a conveyor belt, avoiding excessive accumulation and improving cooling efficiency. Finally, the conveyor belt carries the tea leaves towards the air-cooled housing. The fan blows air through the cooling main pipe to the air outlet, where it cools the tea leaves. Simultaneously, the conveyor belt contacts the spiral cooling pipes inside the water-cooled frame, drawing cooling water from the tank into the spiral cooling pipes. This heats the tea leaves at the bottom. The cooled water then enters a heat exchanger for further cooling before returning to the tank, allowing for water recycling. A dehumidifier and dehumidification pipe remove moisture, thus achieving a dual cooling system of water and air, improving cooling efficiency and uniformity.

[0018] Second, this utility model uses a conveyor belt to transport tea leaves. When the conveyor belt rotates to the bottom, the motor is started to drive the rotating roller to rotate, which in turn drives the external cleaning brush to rotate, thereby cleaning the tea leaves adhering to the surface of the conveyor belt and preventing the tea leaves from flowing back and mixing with other batches of tea leaves, thus affecting the quality of the tea leaves.

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0025] Example 1:

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A continuous cooling conveyor line for tea processing includes a support frame 1 and a conveyor belt 11. A cooling mechanism 2 is provided on the outside of the support frame 1, and a cleaning mechanism 3 is provided on the inside of the support frame 1.

[0028] The cooling mechanism 2 includes a feed frame 21, an air-cooled shell 22, and a water-cooled frame 23. Multiple inclined plates 24 are fixedly connected inside the feed frame 21. The top of the inclined plate 24 has a through hole. Cooling branch pipes 25 are installed inside the inclined plate 24. One end of the cooling branch pipe 25 is fixedly connected to a cooling main pipe 26. The bottom of the cooling main pipe 26 is fixedly connected to an air outlet duct 27. A spiral cooling pipe 28 is installed on the inner side of the water-cooled frame 23. A circulating pump 29 is installed at one end of the spiral cooling pipe 28. A heat exchanger 201 is flanged to the other end of the spiral cooling pipe 28. A water tank 202 is installed at one end of the heat exchanger 201.

[0029] Tea leaves are fed into the feed frame 21 and pass through multiple inclined plates 24 arranged in a staggered pattern within the feed frame 21, slowing down the falling speed of the tea leaves. Simultaneously, a fan is activated, directing air from the cooling branch pipe 25 to the interior of the inclined plates 24. The air is then blown out through external vents and through through-holes at the top of the inclined plates 24, allowing the air to reach the tea leaves for initial cooling and reducing the weight of the falling tea leaves on the inclined plates 24, preventing breakage. The tea leaves then slowly fall onto the conveyor belt 11, preventing them from accumulating too thickly at once, thus improving the cooling effect. The conveyor belt 11 then moves the tea leaves towards the air-cooled housing 22. The air flows through the cooling main pipe 26 to the air outlet 27, where it blows air to cool the tea leaves. Simultaneously, as the conveyor belt 11 moves, it comes into contact with the spiral cooling pipe 28 inside the water-cooled frame 23. The circulating pump 29 draws cooling water from the water tank 202 into the spiral cooling pipe 28, thus exchanging heat with the tea leaves at the bottom. The cooled water then enters the heat exchanger 201, where it is cooled before returning to the water tank 202. This allows the cooling water to be recycled. Meanwhile, a dehumidifier and a dehumidification pipe remove moisture, thus completing the cooling operation of the tea leaves through a dual cooling method of water cooling and air cooling, achieving the effect of improving cooling efficiency and the uniformity of tea leaf cooling.

[0030] Specifically, the feed frame 21 and the air-cooled shell 22 are both fixedly connected to the top of the support frame 1, and the water-cooled frame 23 is fixedly connected to the inside of the support frame 1.

[0031] The above technical solution enables the support frame 1 to support the feed frame 21, the air-cooled shell 22 and the water-cooled frame 23, thereby improving stability.

[0032] Specifically, one end of the cooling manifold 26 is connected to a fan, and the other end of the cooling manifold 26 passes through the air-cooled shell 22 and extends into the interior of the air-cooled shell 22.

[0033] The above technical solution enables air cooling via a fan.

[0034] Specifically, the cooling branch pipe 25 is designed in a forked shape, and an air outlet is provided on the outside of the cooling branch pipe 25.

[0035] The above technical solution uses a branched cooling pipe 25 to cool the tea leaves at multiple inclined plates 24.

[0036] Specifically, there are multiple air outlet hoppers 27, and the multiple air outlet hoppers 27 are arranged in a linear array.

[0037] By using the above technical solution and setting up multiple air outlets 27, the range and efficiency of air cooling can be improved.

[0038] Specifically, the outer wall of the spiral cooling pipe 28 is attached to the outer wall of the conveyor belt 11, and both ends of the spiral cooling pipe 28 penetrate the water-cooling frame 23 and extend to the outside of the support frame 1.

[0039] Through the above technical solution, the outer wall of the spiral cooling pipe 28 is attached to the outer wall of the conveyor belt 11, so that the conveyor belt 11 can exchange heat with the tea leaves when it carries the tea leaves through the spiral cooling pipe 28.

[0040] Specifically, a dehumidifier is installed on the outside of the air-cooled shell 22, and a dehumidification pipe is installed at one end of the dehumidifier.

[0041] The above technical solution removes the generated moisture through the dehumidifier and dehumidification pipe. The dehumidifier is existing technology, and its working principle is well known to those skilled in the art, so it will not be described in detail.

[0042] Example 2:

[0043] Please see Figure 3-4 Furthermore, in conjunction with Embodiment 1, it is further found that the cleaning mechanism 3 includes a cleaning frame 31, a rotating roller 32 is rotatably connected to the inner side of the cleaning frame 31, and a cleaning brush 33 is installed on the outer side of the rotating roller 32.

[0044] The cleaning frame 31 is fixedly connected to the inside of the support frame 1, and one end of the cleaning brush 33 is attached to one end of the conveyor belt 11.

[0045] A motor is installed at one end of the rotating roller 32, and one end of the motor is fixedly connected to one end of the support frame 1.

[0046] Through the above technical solution, tea leaves are transported by the conveyor belt 11. When the conveyor belt 11 rotates to the bottom, the motor is started to drive the rotating roller 32 to rotate, thereby driving the external cleaning brush 33 to rotate, thereby cleaning the tea leaves adhering to the surface of the conveyor belt 11, preventing the tea leaves from flowing back and mixing with other batches of tea leaves, which would affect the quality of the tea leaves.

[0047] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
