The tea processing technology is mainly divided into five steps: picking, drying, screening, coarse frying and fine frying. Black tea is a widely planted and consumed tea. Its quality and taste vary due to its growing conditions, picking time and production process. In the process of tea picking, in order to ensure the quality and taste of black tea, the picked tea leaves need to be screened and classified. The traditional screening method usually adopts manual screening, which is not only inefficient, but also the quality of the screened tea leaves is unstable. Therefore, the development of a device that can automatically, efficiently and accurately screen black tea is an urgent need in the process of tea picking.
