Abstract
Description
Technical Field
[0001] This utility model relates to the field of bitter tea processing technology, and in particular to a bitter tea processing and drying device. Background Technology
[0002] Buckwheat tea is a beverage made from buckwheat. Drying is a key step in its processing. Buckwheat tea drying equipment is designed to reduce the moisture content of buckwheat to a suitable level through specific technical means, while ensuring that the quality and nutritional components of buckwheat are not damaged, so as to meet the production requirements of buckwheat tea.
[0003] In the field of buckwheat tea processing, the traditional drying process generally adopts a static drying method in which buckwheat is placed directly on a drying plate. In this method, the buckwheat is in a static state and is dried by natural convection of hot air. The heat conduction efficiency is low and the buckwheat is not heated evenly, resulting in the surface being over-dried while the internal moisture remains, which seriously affects the quality of buckwheat tea. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying device for processing bitter tea.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for processing bitter tea, comprising a drying box, a fan fixedly connected to the drying box, a heating box fixedly connected to the drying box, a heating tube fixedly connected to the heating box, an input end of the fan connected to a heating element, an output end of the fan fixedly connected to an air outlet pipe, a plurality of nozzles provided on the air outlet pipe, a high-efficiency structure provided on the drying box, the high-efficiency structure mainly consisting of two sliders, the two sliders respectively disposed on the inner walls of the two sides of the drying box, a rotating shaft rotatably connected to the sliders via bearings, the rotating shaft being fixedly connected to a rotating cylinder, a door panel hinged to the rotating cylinder, a feed hopper fixedly connected to the drying box, and a collection box slidably inserted into the drying box.
[0006] The effects achieved by the above components are as follows: The fan is started, pumping outside air through the heating chamber to the outlet pipe. As the air passes through the heating chamber, the heating element heats it, and the air is then blown onto the buckwheat through several nozzles for drying. The door is opened, and the rotating drum is rotated so that the high-efficiency structure faces upwards. Buckwheat is fed through the feeding hopper into the drying chamber and then into the rotating drum. The drum is then rotated to prevent the buckwheat from sitting still, thus improving the uniformity and effectiveness of the drying process. After drying, the door is opened, allowing the buckwheat to fall into the collection box for collection. The right end of the rotating drum is slightly lower than the left end for easy unloading. This avoids the situation where the buckwheat is left to stand, relying solely on natural convection of hot air for drying, resulting in low heat transfer efficiency, poor heating uniformity, and over-drying of the surface while leaving residual moisture inside, which severely affects the quality of the buckwheat tea.
[0007] Preferably, the inner walls on both sides of the drying oven are provided with sliding grooves, and the sliding grooves are slidably connected to the slider.
[0008] The effect achieved by the above components is that the sliding slider can move back and forth to drive the rotating drum to move back and forth, so that the buckwheat in each position is blown more evenly by the wind.
[0009] Preferably, a slide rail is fixedly connected to one of the sliders, a turntable is rotatably connected to one side inner wall of the drying box via a bearing, a limit rod is fixedly connected to the turntable, a drive motor is fixedly connected to the drying box, and the turntable is driven to rotate by the drive motor.
[0010] The effect achieved by the above components is as follows: the output end of the drive motor is connected to the limit rod through the reducer and coupling. The model of the drive motor is 17HS4401. First, the power is turned on to power the control system of the drive motor. Then, the drive motor is started to drive the turntable to rotate. The rotation of the turntable can drive the limit rod to make a circular motion. Since the limit rod slides in the slide rail, it can drive the slider to slide back and forth through the slide rail, making the operation more convenient.
[0011] Preferably, a gear is fixedly connected to one of the rotating shafts, and a rack is meshed with the gear, the rack being fixedly connected to the inner wall of the drying oven.
[0012] The effect achieved by the above components is that when the slider slides, it drives the gear to move, and due to the limit of the rack, the rotating shaft will drive the rotating drum to rotate. Moreover, the direction of the slider's sliding can make the rotating shaft rotate in different directions.
[0013] Preferably, the drying box is provided with a recycling structure, which mainly consists of an exhaust fan. The exhaust fan is fixedly connected to the drying box, and an exhaust pipe is fixedly connected to the drying box.
[0014] The effect achieved by the above components is that the exhaust fan can be activated during the drying process to expel the hot and humid air from the drying chamber.
[0015] Preferably, a heat exchange box is fixedly connected to the drying box, the heat exchange box is connected to the heating box, a heat exchange tube is fixedly connected in the heat exchange box, and the heat exchange tube is connected to the exhaust pipe.
[0016] The effect achieved by the above components is that the exhaust hot air enters the heat exchange tube, and the outside air enters the heat exchange box and transfers heat with the hot air in the heat exchange tube, which can preliminarily heat the outside air to reduce energy consumption.
[0017] Preferably, an air inlet pipe is fixedly connected to the heat exchange box, and a filter plate is fixedly connected to the air inlet pipe.
[0018] The effect achieved by the above components is that outside air enters the heat exchange box through the air inlet pipe, and the filter plate can filter the air.
[0019] Preferably, an insulation sleeve is fixedly connected to the pipe connecting the heat exchange tube and the exhaust pipe, and several heat-conducting fins are fixedly connected to the heat exchange tube.
[0020] The effects achieved by the above components are as follows: the insulation jacket is made of polyurethane foam, and the heat-conducting sheet can increase the contact area and improve the heat exchange effect.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting up a high-efficiency structure, the fan is started, and the fan pumps the outside air through the heating box to the air outlet pipe. When passing through the heating box, the heating tube is activated to heat the air, and the air is blown onto the buckwheat through several nozzles to dry it. The door panel is opened, and the rotating drum is rotated so that the high-efficiency structure faces upward. The buckwheat is fed through the feeding hopper and put into the drying box and into the rotating drum. Then the rotating drum is rotated to prevent the buckwheat from sitting still, so as to improve the uniformity and effect of drying the buckwheat. After drying, the door panel is opened so that the buckwheat falls into the collection box for collection. The right end of the rotating drum is slightly lower than the left end for easy unloading. This avoids the situation where the buckwheat is in a static state and is dried by natural convection of hot air, which has low heat conduction efficiency and poor heating uniformity, resulting in over-drying of the surface while the internal moisture remains, which seriously affects the quality of buckwheat tea.

[0027] Example 1, such as Figure 1 and Figure 2 As shown, a bitter tea processing and drying device includes a drying box 1, a fan 2 fixedly connected to the drying box 1, a heating box 7 fixedly connected to the drying box 1, a heating tube 8 fixedly connected in the heating box 7, the input end of the fan 2 is connected to the heating box 1, and the output end of the fan 2 is fixedly connected to the air outlet pipe 3, with a plurality of nozzles 4 provided on the air outlet pipe 3.
[0028] Reference Figures 1 to 3The drying chamber 1 is equipped with a high-efficiency structure 5, which mainly consists of two sliders 51. The two sliders 51 are respectively set on the inner walls of both sides of the drying chamber 1. A rotating shaft 52 is rotatably connected to the slider 51 through a bearing. The rotating shaft 52 is fixedly connected to the rotating drum 53. A door panel 54 is hinged to the rotating drum 53. A feed hopper 55 is fixedly connected to the drying chamber 1. A collection box 513 is slidably inserted into the drying chamber 1. The blower 2 is started, and the blower 2 pumps the outside air through the heating box 7 to the air outlet pipe 3. When passing through the heating box 7, the heating pipe 8 is activated to heat the air and blow it onto the buckwheat through several nozzles 4 to dry it. The door panel 54 is opened and the rotating drum 53 is rotated. With the high-efficiency structure 5 facing upwards, the buckwheat is fed into the drying chamber 1 through the feed hopper 55 and then into the rotating drum 53. The rotating drum 53 is then rotated to prevent the buckwheat from sitting still, thereby improving the uniformity and effect of drying. After drying, the door panel 54 is opened, allowing the buckwheat to fall into the collection box 513 for collection. The right end of the rotating drum 53 is slightly lower than the left end for easy unloading. This avoids the situation where the buckwheat is left to sit and is dried solely by natural convection of hot air, resulting in low heat transfer efficiency, poor heat uniformity, and over-drying of the surface while leaving residual moisture inside, which seriously affects the quality of the buckwheat tea. The drying chamber 1 has openings on both inner walls. A chute 56 is provided, which is slidably connected to a slider 51. The slider 51 can slide back and forth, driving the rotating drum 53 to move reciprocally, so that the buckwheat in each position is blown more evenly by the air. A slide rail 57 is fixedly connected to one slider 51. A turntable 58 is rotatably connected to one side of the inner wall of the drying chamber 1 via a bearing. A limit rod 59 is fixedly connected to the turntable 58. A drive motor 510 is fixedly connected to the drying chamber 1. The turntable 58 is driven to rotate by the drive motor 510. The output end of the drive motor 510 is connected to the limit rod 59 through a reducer and a coupling. The model of the drive motor 510 is 17HS4401. First, the power is connected to the control system of the drive motor 510. When the power is turned on, the drive motor 510 can drive the turntable 58 to rotate. Rotating the turntable 58 can drive the limit rod 59 to make a circular motion. Since the limit rod 59 is limited to slide in the slide rail 57, the slider 51 can be driven to slide back and forth through the slide rail 57, making the operation more convenient. A gear 511 is fixedly connected to a rotating shaft 52. A rack 512 is meshed on the gear 511. The rack 512 is fixedly connected to the inner wall of the drying box 1. When the slider 51 slides, it will drive the gear 511 to move. Since the rack 512 is limited, the rotating shaft 52 will drive the rotating drum 53 to rotate. The direction of the slider 51's sliding will make the rotation direction of the rotating shaft 52 different.
[0029] Reference Figures 1 to 4The drying chamber 1 is equipped with a recovery structure 6, which mainly consists of an exhaust fan 61. The exhaust fan 61 is fixedly connected to the drying chamber 1, and an exhaust pipe 62 is fixedly connected to the drying chamber 1. During the drying process, the exhaust fan 61 can be activated to exhaust the hot and humid air in the drying chamber 1. A heat exchange box 63 is fixedly connected to the drying chamber 1 and is connected to the heating box 7. A heat exchange tube 64 is fixedly connected to the heat exchange box 63 and is connected to the exhaust pipe 62. The exhaust hot air enters the heat exchange tube 64, and the outside air enters the heat exchange box 63 and reacts with the heat exchange tube 64. The hot air in the heat pipe 64 transfers heat, which can preheat the outside air to reduce energy consumption. An air inlet pipe 65 is fixedly connected to the heat exchange box 63, and a filter plate 66 is fixedly connected to the air inlet pipe 65. Outside air enters the heat exchange box 63 through the air inlet pipe 65, and the filter plate 66 can filter the air. An insulation sleeve 67 is fixedly connected to the pipe connecting the heat exchange pipe 64 and the exhaust pipe 62. Several heat-conducting plates 68 are fixedly connected to the heat exchange pipe 64. The insulation sleeve 67 is made of polyurethane foam, and the heat-conducting plates 68 can increase the contact area and improve the heat exchange effect.
[0030] Working principle: The blower 2 is started, pumping outside air through the heating box 7 to the outlet pipe 3. As the air passes through the heating box 7, the heating pipe 8 heats it, and the air is then blown onto the buckwheat through several nozzles 4 for drying. The door panel 54 is opened, and the rotating drum 53 is rotated so that the high-efficiency structure 5 faces upwards. Buckwheat is fed through the feed hopper 55 into the drying chamber 1 and into the rotating drum 53. The rotating drum 53 is then rotated to prevent the buckwheat from remaining still, thus improving the uniformity and effectiveness of the drying process. After drying, the door panel 54 is opened, allowing the buckwheat to fall into the collection tray. The buckwheat is collected in the collection box 513. The right end of the rotating drum 53 is slightly lower than the left end for easy unloading. This avoids the situation where the buckwheat is left to stand and is dried solely by natural convection of hot air, resulting in low heat transfer efficiency and poor heat uniformity. This can lead to over-drying of the surface while leaving residual moisture inside, severely affecting the quality of the buckwheat tea. The sliding slider 51 moves the rotating drum 53 back and forth, ensuring more even airflow to all parts of the buckwheat. The output of the drive motor 510 is connected to the limit rod 59 via a reducer and coupling. Model 10 is 17HS4401. First, connect the power supply to power the control system of drive motor 510. Then, start drive motor 510 to drive turntable 58 to rotate. Rotating turntable 58 drives limit rod 59 to make circular motion. Since limit rod 59 slides in slide rail 57, it can drive slider 51 to slide back and forth through slide rail 57, making operation more convenient. When slider 51 slides, it drives gear 511 to move. Due to the limit of rack 512, rotating shaft 52 will drive rotating cylinder 53 to rotate. And the direction of slider 51 sliding... Different directions can cause the rotating shaft 52 to rotate in different directions. During the drying process, the exhaust fan 61 can be started to exhaust the hot and humid air in the drying chamber 1. The exhaust hot air enters the heat exchange tube 64. After the outside air enters the heat exchange chamber 63, it transfers heat with the hot air in the heat exchange tube 64, which can preliminarily heat the outside air to reduce energy consumption. The outside air enters the heat exchange chamber 63 through the air inlet pipe 65. The filter plate 66 can filter the air. The insulation jacket 67 is made of polyurethane foam. The heat-conducting plate 68 can increase the contact area and improve the heat exchange effect.
