Problems solved by technology

Once dried, the appearance is dark green, the pekoe is more exposed but dull, the inner aroma is more obvious, the soup is dark yellow, and the taste is more mellow but weak.
[0005] The publication number is CN102018063A, and the Chinese invention patent published on April 20, 2011 discloses a white tea processing technology. Fresh tea leaves are picked, spread evenly on the withering tank, withered for 15-20 hours, and rolled for 3-5 minutes. , dried until the water content of raw tea is 6±0.5%. The invention adds a "rolling" process to enhance the taste of the product. The product has a tight appearance and is conducive to enhancing the concentration and thickness of the taste, but the aroma of the produced white tea is not strong enough. , the duration is not long enough; and the withering time is long, and the withering is too heavy, so the taste of white tea is not strong enough, and the mellowness is not high enough.
