Invention patents CN103349117A and CN106260296A also describe a similar intermittent rolling method. The main feature is that the fresh leaves of the first grade are kneaded every 10 minutes and shut down for 5 minutes, and kneaded for 90 minutes. The second and third grades of fresh leaves are kneaded every 10 minutes. Describe in detail the light-heavy-light pressurization principle
Studies have shown that fermenting at a low temperature below 28°C will easily decompose and produce dark brown polyphenolic compounds, resulting in sour and astringent taste, which will affect the quality of tea products
