Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a clean production process of tea. Background technique [0002] Tea is a necessity in our life. The first procedure we usually drink tea is "washing tea". Impurities wash away. However, in order to show the quality of the tea leaves, part of the nutrients in the fresh tea leaves are spilled and exposed on the surface of the tea sticks during processing. When the tea leaves are dried, the spilled nutrients such as proteins, amino acids, and tea polyphenols are attached in a crystalline state. On the surface of tea sticks, these substances are water-soluble substances. Once they come into contact with hot water, they will dissolve in large quantities in water within a few seconds. Therefore, although washing tea washes away impurities, it also washes out a lot of nutrients. Therefore, the clean production of tea is very necessary. Contents of the invention [0003] Th...
