With the improvement of people's living standards, the demand for tea is increasing, and consumers' requirements for tea quality are also increasing. Wind separation is one of the key processes to improve tea quality. In the tea processing process, wind separation is usually used to separate the non-tea substances such as yellow flakes, stems, and broken powder adsorbed in the tea production process from the finished tea, so as to achieve the goal of tea grading and improve tea quality. The most commonly used machine for tea sorting is the tea wind sorter.
[0003] After searching, the patent announcement number CN216728265U discloses a tea air selection device, including a tea air selection box, a feeding port for feeding tea into the tea air selection box, a blower for blowing air into the tea air selection box and an air inlet channel connected to the blower; a filter plate for filtering tea leaves is fixed at the end of the tea air selection box away from the blower; a plurality of dividing plates for dividing the tea air selection box into sections are fixed in the tea air selection box; a plurality of discharge ports for discharging air-selected tea leaves are fixed at the lower end of the tea air selection box, and a wind shelter is provided at the discharge port to prevent wind from being discharged from the discharge port; but the dust and dirt treatment is not satisfactory, and some dust, fine sand, etc. will enter the next process with the tea leaves.
