The drying head 43 is located inside the screening chamber 1. One side of the drying head 43 is connected to the conveying pipe 42, and one end of the conveying pipe 42 is connected to the drying chamber 41. The heating wire 47 is located inside the drying chamber 41. The second air pump 44 is located on one side of the drying chamber 41. A filter head 46 is located at the air inlet of the second air pump 44, and a connecting seat 45 is located at one end of the filter head 46.
[0035] By adopting the above technical solution, the filter head 46 is installed at the air inlet of the second air pump 44 through the connecting seat 45, so that the extracted air can be filtered. When the black tea is being sieved, the second air pump 44 is turned on to draw outside air into the drying box 41. The drying box 41 is equipped with a heating wire 47, which can heat the incoming air. After the air is heated, the conveying pipe 42 will deliver it into the drying head 43, and then spray it out from the drying head 43, thereby drying the black tea during sieving and removing its internal moisture.
[0036] Specifically, the heating wire 47 is provided with fixing seats at both ends, and the heating wire 47 is installed inside the drying oven 41 through the fixing seats.
[0037] By adopting the above technical solution, the heating wire 47 is provided with fixing seats at both ends, and the heating wire 47 is installed inside the drying oven 41 through the fixing seats, thereby preventing the heating wire 47 from falling off.
[0038] In this embodiment, the heating wire 47 is fixed at both ends and is installed inside the drying chamber 41 through the fixed base to prevent it from falling off. The filter head 46 is installed at the air inlet of the second air pump 44 through the connecting base 45 to filter the drawn air. When the black tea is being sieved, the second air pump 44 is turned on to draw outside air into the drying chamber 41. The heating wire 47 is installed inside the drying chamber 41 to heat the incoming air. After being heated, the air is conveyed into the drying head 43 through the conveying pipe 42 and then sprayed out from the drying head 43 to dry the black tea during sieving and remove its internal moisture.
[0039] In this utility model, the heating wire 47 is a previously disclosed technology, and the selected model is XT8685.
[0040] The structure and operating principle of the feed inlet 5, vibration motor 6, multi-stage screening component 7, and cleaning component 8 of this utility model have been disclosed in a tea sieving machine with grading function published in Chinese Patent Publication No. CN221246030U.
[0041] The working principle and usage process of this utility model: This utility model is used for dust handling in a refined black tea powder separation device. During operation, it is necessary to suck up the raised dust. When the black tea leaves are sieved, the air pump 37 is turned on, and the dust is sucked up through the suction head 33 below the dust suction cover 31 to prevent the dust from spreading and polluting the surrounding environment. After being sucked up, the dust is conveyed by the suction pipe 34 into the filter box 35. The filter box 35 is equipped with a filter plate 38, which can filter out the dust in the air. After being filtered out, the dust falls onto the guide plate 39. Then, guided by the guide plate 39, it falls into the collection drawer 310. Since the spring rod 362 is installed on the surface of the filter plate 38 through the fixing bracket 361, and the top of the spring rod 362 is provided with a striking head 364, when the filter plate 38 needs to be cleaned, the motor 363 is turned on to drive the eccentric wheel 365 to rotate. The rotation of the eccentric wheel 365 will hit the spring rod 362. After the spring rod 362 is hit, the striking head 364 will knock the filter plate 38, causing the dust attached to the surface of the filter plate 38 to fall off. After the striking head 364 knocks the filter plate 38, it will be reset by the rebound of the spring rod 362.
[0042] In use, the tea drying process of the refined black tea powder separation device involves drying the sifted black tea leaves. The heating wire 47 has fixed bases at both ends, and is installed inside the drying chamber 41 via these bases to prevent it from falling off. The filter head 46 is installed at the air inlet of the second suction pump 44 via a connecting base 45, thus filtering the extracted air. When the black tea leaves are sifted, the second suction pump 44 is turned on to draw outside air into the drying chamber 41. The heating wire 47 is installed inside the drying chamber 41 to heat the incoming air. After heating, the air is conveyed through the conveying pipe 42 into the drying head 43, and then sprayed out from the drying head 43, thereby drying the sifted black tea leaves and removing their internal moisture.
