Description

Technical Field

[0001] The invention relates to the technical field of tea seed processing, in particular to a tea seed drying and processing device. Background Art

[0002] Tea seeds are a raw material for extracting high-quality edible oil. The tea oil extracted from tea seeds has an unsaturated fatty acid content of more than 90%, and does not contain erucic acid. It is more resistant to storage than other edible oils and is not easy to become rancid. Edible tea oil not only does not increase human cholesterol, but is also suitable for patients with hypertension. It also has health benefits such as weight loss, lowering blood lipids, and preventing vascular sclerosis. During the oil tea refining process, the tea seeds need to be dried. The existing tea seed drying device generally places the tea seeds in a static oven, which makes it difficult to dissipate heat between the tea seeds, resulting in uneven heating of the tea seeds during the heating process, resulting in uneven drying, which can easily cause some tea seeds to burn, while others are not fully dried, which will affect the subsequent pressing quality. Summary of the invention

[0003] The invention provides a tea seed drying and processing device to solve the deficiencies in the prior art.

[0004] The technical implementation scheme of the present invention is: a tea seed drying and processing device, including a drying bin, an air outlet plate fixedly connected in the drying bin, air outlet holes equidistantly distributed in the circumferential direction are opened on the air outlet plate, a collecting trough is fixedly connected to the inner side of the air outlet plate, a discharge pipe connected to the collecting trough is fixedly connected to the bottom of the drying bin, the combination of the discharge pipe, the collecting trough and the air outlet plate separates the interior of the drying bin into cavity one and cavity two, a detachable cover is installed in the discharge pipe, a feed pipe connected to the drying bin is connected to the top of the drying bin, a conveying cylinder is fixedly connected in the collecting trough, a rotating shaft penetrating the conveying cylinder, the collecting trough and the discharge pipe is rotatably connected to the top of the drying bin, and a spiral conveying blade contacting and cooperating with the inner wall of the conveying cylinder is fixedly connected to the rotating shaft.

[0005] Furthermore, the top surface of the air outlet plate is an inclined conical arc surface.

[0006] Furthermore, an installation box is installed on the top of the drying bin, a motor is installed in the installation box, a gear one is installed on the output shaft of the motor, and a gear two meshing with the gear two is installed at the end of the rotating shaft.

[0007] Furthermore, a heating bin is installed on the drying bin, a filter plate 1 is installed in the heating bin, a fan is installed at the bottom of the filter plate 1, a guide plate 2 is fixed in the heating bin and is located below the fan and is designed to be alternately spaced at equal intervals, heating plates are installed between adjacent guide plates 2, an air inlet pipe is connected to the top of the heating bin, and an exhaust pipe is connected between the bottom of the heating bin and the drying bin.

[0008] Furthermore, a rotating drum is rotatably connected to the conveying drum, a transmission rod is fixedly connected between the top of the rotating drum and the rotating shaft, a plurality of material receiving plates are fixedly connected to the rotating drum, and material guide plates designed alternately with the plurality of material receiving plates are fixedly connected to the two inner walls of the cavity, and each material guide plate is provided with air holes distributed at equal intervals in the circumferential direction.

[0009] Furthermore, each receiving plate is fixedly connected to the top with dividing plates which are circumferentially evenly spaced.

[0010] Furthermore, a guide plate 1 is fixedly connected to the bottom of each guide plate.

[0011] Furthermore, the guide plate is a hollow cone with a top diameter larger than a bottom diameter, and the guide plate 1 is a hollow cone with a top diameter smaller than a bottom diameter.

[0012] Furthermore, a recovery pipe is connected between the air inlet pipe and the top of the drying bin, and two filter plates are installed in the air inlet pipe with equal intervals. A water inlet is opened near the bottom of each filter plate in the air inlet pipe, and a guide groove connected to each water inlet is opened in the air inlet pipe. A water outlet connected to the guide groove is opened outside the air inlet pipe, and a liquid collecting tank located at the water outlet is fixedly connected to the air inlet pipe.

[0013] Furthermore, the second filter plate is a flow-guiding curved filter plate.

[0014] The present invention has the following advantages: 1. The present invention lifts the tea seeds upwards by means of rotating spiral conveying blades, allowing the tea seeds to be repeatedly scattered and dropped from a high place until the tea seeds are completely dried, so that the heat is evenly dispersed among the tea seeds, thereby facilitating the tea seeds to be evenly heated and dried;

[0015] 2. The tea seeds fall on the rotating receiving plate. Under the spacing effect of the dividing plate, the tea seeds are dispersed and piled. Then, under the action of centrifugation, the tea seeds roll outward to be dispersed circumferentially and fall downward. At the same time, the hot air flows upward through the air holes on the guide plate, thereby generating convection with the tea seeds falling downward, so that the two are fully in contact. At the same time, part of the hot air flows to the receiving plate under the guidance of the guide plate 1 to dry the tea seeds.

[0016] 3. After passing through the drying chamber, the hot air re-enters the air intake pipe through the recovery pipe. The second filter plate in the air intake pipe filters and separates the water vapor in the hot air. Since the second filter plate is an arc-shaped filter plate, the water vapor condenses into water droplets and flows into the guide groove through the water inlet, and then flows into the collecting tank through the water outlet. The hot air with water vapor removed re-enters the heating chamber for waste heat recovery, thereby accelerating the temperature rise of the air entering the heating chamber and improving work efficiency.

Each heating bin 21 is fixed with a guide plate 24 located below the fan 23 and designed to be alternately spaced at equal intervals, and heating plates 25 distributed at equal intervals are installed between two adjacent guide plates 24. The top of each heating bin 21 is connected to an air inlet pipe 26, and the bottom of each heating bin 21 is connected to the drying bin 1 with an exhaust pipe 27.

[0029] Preferably, the top of each receiving plate 16 is fixedly connected with a dividing plate 17 which is distributed at equal intervals in the circumferential direction.

[0030] Preferably, a guide plate 20 is fixedly connected to the bottom of each guide plate 19 .

[0031] Preferably, the guide plate 19 is a hollow cone with a top diameter larger than the bottom diameter, and the guide plate 20 is a hollow cone with a top diameter smaller than the bottom diameter.

[0032] Preferably, the two air inlet pipes 26 are connected to the top of the drying chamber 1 via a recovery pipe 31, three vertically arranged filter plates 28 are installed in the two air inlet pipes 26, a water inlet 32 ​​is provided in each air inlet pipe 26 near the bottom of each filter plate 28, a guide groove 30 connected to each water inlet 32 ​​is provided in the air inlet pipe 26, a water outlet 33 connected to the guide groove 30 is provided outside the air inlet pipe 26, and a liquid collecting tank 29 located at the water outlet 33 is fixedly connected to the air inlet pipe 26.

[0033] Preferably, the second filter plate 28 is a flow-guiding arc-shaped filter plate.

[0034] Working principle: When in use, start the motor 6, the motor 6 drives the shaft 8 to rotate through the transmission of gear 1 7 and gear 2 9, the shaft 8 drives the transmission rod 18 to rotate, the transmission rod 18 drives the drum 15 to rotate, the drum 15 drives the receiving plate 16 to rotate, and the shaft 8 drives the spiral conveying blade 10 to rotate. When the tea seeds are loaded into the drying bin 1 through the feed pipe 5, the tea seeds fall on the rotating receiving plate 16, and under the spacing effect of the dividing plate 17, the tea seeds are dispersed and accumulated, and then under the action of centrifugation, the tea seeds roll outward to be dispersed circumferentially and fall downward to the guide plate 19. Since the guide plate 19 is a hollow cone with a top diameter larger than the bottom diameter, the tea seeds continue to roll downward in the center and fall onto the next receiving plate 16 for repeated movement. In this way, each tea seed can be evenly heated during the rolling, dispersion and falling process. When the tea seeds fall into the discharge port and the collecting trough 13, the rotating spiral conveying blades 10 lift the tea seeds upward, and the above operation is repeated until the tea seeds are completely dried. Since the top surface of the air outlet plate 14 is an inclined conical arc surface, when the tea seeds fall on the air outlet plate 14, they can roll into the collecting trough 13.

[0035] Start the fan 23. The fan 23 rotates to draw outside air into the heating chamber 21 through the air inlet pipe 26. The outside air is filtered by the filter plate 28 in the air inlet pipe 26 and the filter plate 1 22 in the heating chamber 21. Then, the time of the outside air in the heating chamber 21 is prolonged by the guide plate 24, so that the heating plate 25 can fully heat it. Then, the outside air enters the cavity 101 of the drying chamber 1 through the exhaust pipe 27. The hot air enters the cavity 202 through the air outlet hole of the air outlet plate 14, thereby drying the tea seeds in the cavity 202. Since the guide plate 19 is provided with air holes, the hot air flows upward through the air holes on the guide plate 19, thereby producing tea seeds falling downward. Convection phenomenon occurs, so that the two are in full contact. At the same time, part of the hot air flows to the receiving plate 16 under the guiding effect of the guide plate 20, so that the moving tea seeds can be in full contact with the hot air. After passing through the drying chamber 1, the hot air re-enters the air inlet pipe 26 through the recovery pipe 31. The filter plate 28 in the air inlet pipe 26 filters and separates the water vapor in the hot air. Since the filter plate 28 is an arc-shaped filter plate, the water vapor condenses into water droplets and flows into the guide groove 30 through the water inlet 32, and then flows into the collecting tank 29 through the water outlet 33. The hot air with water vapor removed re-enters the heating chamber 21 for waste heat recovery, thereby accelerating the temperature rise of the air entering the heating chamber 21 and improving work efficiency.
