Problems solved by technology

However, now tea companies are influenced by the traditional concept of famous and high-quality tea, excessively pursuing the appearance quality of tea, and ignoring the requirements of tea as a traditional hobby drink in terms of flavor quality
Generally speaking, in recent years, green tea production enterprises have focused on highlighting the color and shape of the finished tea. The fresh leaf raw materials used are too young and the processing technology is relatively simple, resulting in internal quality defects such as relatively thin taste and low aroma. It also brings about the high cost of fresh leaf raw materials and the high price of finished tea, which is unbearable for ordinary consumers.
